A capacitance micrometer on the wafer chuck and those on the mask chuck are used in this method. The mask and wafer surfaces are positioned parallel to the travel plane of the wafer x-y stage so that the gap does not vary with the step and repeat motion of the wafer stage. Therefore, gap setting is required only once for each wafer, and the throughput becomes better. This method has the following two additional merits. A complex gap measurement optics is not required and the setting value of the gap is variable. The gap setting error caused by mask unflatness, wafer unflatness and travel error of the wafer x-y stage was analyzed. Experiments were carried out using mask and wafer stages both with 6-axes. A gap setting accuracy better than •}1.5 pm at the exposure positions of 5 wafers has been achieved for 30 pm and 20 pm","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"69 1","pages":"56-61"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81355370","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}

As a result of the experiments, the actuator is capable of generating enough force up to attain saturation of a movement of a piano's action, and of controlling a wide range of hammer struck string velocity down to the smallest tone volume. Also, the optimum signal wave form is found by analyzing the motion of the key and the hammer.

Design decisions are made so that smaller design sensitivity coefficients of the characteristics are given for areas that have been estimated to have a great potential for variation in the design variables. First, fundamental design principles are established for minimizing variations of the characteristics. Then, the practical procedures are presented for decreasing the variations of the product performance. The proposed method in which the minimization of variations of the product performance is the main objective corresponds to a maximization of the product performance and also brings about a decrease of the manufacturing cost. Finally, the effectiveness of the design decision making methods are demonstrated for designing a machine tool structure.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"105 1","pages":"1215-1220"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81284777","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}

Around the entrance and exit part of each grinding pass, the local thermal bending deformation occurs.
