Patent JP-S57168516-A (JP)
Title: Surface acoustic wave filter
Inventor: KOJIMA YUUJI
IPC: H03H9/145
Filed: 1981-04-10
Abstract: PURPOSE:To eliminate the mismatching of the cross impedance which is caused when matching two patterns forming a transducer, by adding a cut area to a comb-shaped electrode at a junction part. CONSTITUTION:The patterns A and B forming a transducer are formed on a substrate made of a piezoelectric crystal with the standardization of the maximum cross width. To eliminate in this case, the mismatching caused to the cross impedance, the pattern B is shifted in accordance with a comb-shaped electrode 5 of the pattern A to match the envelope curves of both patterns. As a result, a conventional cut area 6' is shifted to form new cut areas 6'' and 8'. The original cut area 6' of the inner side corresponds to a cut area 5' of pattern A and is accordingly kept as it is. Then the weighting is newly caused at the center part by a shift of pattern B. In this connection, the position 5'' of an electrode 5 corresponding to the area 6'' is newly cut. Thus the mismatching of impedance can be eliminated.

Abstract: PURPOSE:To obtain a mirror optical device provided with structure contributing to the lightweight of the whole device, high vibration resistance and high impact resistance by constituting a main mirror and a sub-mirror which are arranged to be faced and a column of an identical material. CONSTITUTION:As for the mirror optical device constituted so that the main mirror 1 and the sub-mirror 5 which are arranged to be faced are coupled by the plural column 2, the mirrors 1 and 5 and the columns 2 are constituted of the identical material. Then, the mirror 5 is held by a sub-mirror holding part 4 and the holding part 4 is supported by a sub-mirror base plate 3 connected to the columns 2. When these members are slightly deformed after vibration, acceleration and impact are added, positional relation between the mirrors 1 and 5 is changed and optical performance is deteriorated. Therefore, it is preferable that the material showing brittleness according to environmental change such as the using temperature or the carrying temperature of the device is used as the respective members. When the brittle material is used, the strength is low in comparison with a metallic material but there is hardly residual distortion after stress acts and it is eliminated. As a result, high accurate assembly is realized.

IPC: B30B13/00
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To efficiently and accurately punch product portions to form credit cards and the like, which are arranged and formed on a seat. SOLUTION: A seat 6 is intermittently transferred by a roller type transferring device 15 and the like, and product portions are sequentially punched from the seat 6. Before the punching, the position of a reference mark formed on the seat in correspondent to each product portion is detected by a camera 51 or the like. Thus, the feed volume by the roller type transferring device 15 is adjusted so as to position the seat 6 at the time of punching. When the punching is carried out to the seat 6, the position of a reference mark corresponding to the unpunched product portions of the same seat 6 is detected, resulting in the improvement of efficiency. Since the feed volume of the seat 6 from the reference mark position detecting to punching is shortened, punching accuracy is also improved.
