A new mouse type device named active mouse is developed. It consists of one omni-traveling mechanism, force sensor, position sensor and communication and control system. The omni-traveling mechanism consists of one sphere ball, two differential mechanisms, and two motors. This mechanism realizes rotation of one motor that will not affect the other motor. Therefore, output of the two motors can be composed as output to the ball. As a result, this omni-traveling mechanism can achieve 4.8[N] force at 5[V] and 500 [mAJ in compact size. The two motors of omni-traveling mechanism, force sensor and position sensor are controlled with communication and control modules developed in this research. The communication system for Active Mouse equips with USB interface. The USB interface supplies DC voltage and support communication with PC. Therefore this device can be used for general PC just connecting USB interface. To confirm function ability of the Active Mouse, a graphical program is developed. Using this program, Active Mouse can input user's force and position data to PC, and output force to user. From here, Active Mouse realizes functions of general mouse and also works as haptic device.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122062162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This anomalous fluctuation can be evidence that there exists some cooperativity among the motors in action because fluctuation should be averaged out if the action of each motor is independent. In order to understand the nature of the cooperativity in existing models of molecular motors, we perform numerical simulations and analyze velocity correlation on three models that are known to show some kind of cooperativity and/or large diffusion coefficient in the long filament limit. It is shown that Prost model (1994) and Duke model (1999) do not give a finite diffusion in the long filament limit in spite of collective action of motors. Quenched randomness in Sekimoto-Tawada model (1995) has been shown to give constant diffusion coefficient independent of filament length because of long time correlation proportional to filament length, but such a long correlation time is found to conflict with the experimental time scales. We conclude that none of the three models represent experimental findings, and a mechanism to be understood should allow both the amplitude and the time scale of the velocity correlation to be independent of the filament length.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127105515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Towards the final goal, we designed and developed a disposable-type three-compartment micro-cell culture using polydimethylsiloxane (PDMS)-based microfabrication and small magnetic stirrer-based internal pumping system (for disposability and space-saving). The developed device was able to be operated in two different perfusion modes, that is, an each compartment perfusion mode and an entire device perfusion mode, so that cells derived from different tissue/organ can be grown or maintained in different culture protocols and finally they are connected for toxicokinetic studies over the entire device. To evaluate the chemical distribution and biological metabolic processes, we incorporated fat and liver-tissue derived cells in the device because they control the distribution and biotransformation of hydrophobic and carcinogenic chemicals. Liver-derived cells, human hepatocarcinoma Hep G2, were inoculated and cultured in the liver compartment in addition to the fat tissue compartment where mature rat adipocytes were immobilized in a 3D scaffold. Both cells remained attached to the surface in monolayers on the bottom surfaces of each compartment without detachment or forming floating aggregates during perfusion. Rat primary hepatocytes were also stably cultured in the liver tissue compartment. We are now trying fluorescent-based visualization of toxicokinetic processes in the liver compartment in the present and absence of rat tissue compartment in the devices administered with fluorescent and carcinogenic chemicals.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123283657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A coupled Fluid-Structure analytical model, which can predict the friction force and the distribution of the material removal rate, is developed. Oxide CMP experiments are conducted using a fabricated CMP system, and measured friction force and distribution of the material removal rate are compared with the analytical results. As a result, it is confirmed that the wafer's rotational speed affects the friction force and the distribution of the material removal rate. Additionally, the results determined by the developed analytical model agree with the measurements. The magnitude of the friction force under a condition in which the wafer does not rotate becomes smaller than when the wafer rotates at the same speed as the polishing pad. The direction of the friction force inclines against the rotational center of the polishing pad. The material removal rate when the wafer does not rotate is high around the edge of the wafer as compared with that at other areas. In particular, it becomes high around the leading edge and the area where the rotational radius of the polishing pad is large. These specific characteristics of the friction force and the distribution of the material removal rate are explained using the analytical results.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123019792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
