Title: Optical head guide mechanism
Inventor: SUGIYAMA SUNAO
IPC: G11B21/02
Filed: 1990-11-21
Abstract: PURPOSE:To reduce the frictional resistance and the weight of a head guide mechanism by laying belt-like resilient material sheets on one another to make them flat and sandwiching the guide portion of an optical head between the contact surfaces of a guide belt inserted between guide surfaces opposed to each other in parallel. CONSTITUTION:Two sets in each of which a pair of guide belts 103a and 103b made of belt-like resilient material sheets are assembled into between opposed guide surfaces as deformed flat are symmetrically arranged on both sides of an optical head 101. The optical head 101 is supported such that it is sandwiched between two sets of the guide belts by flat-plate-like guide portions 102a and 102b provided on both sides of the optical head 101. Thus, when the optical head receives a force, the guide belts are deformed and the optical head moves in parallel. Since there is no sliding portion in a movement described before, no sliding resistance is generated and a resistance is only an internal loss due to the deflection of the belts. Thus, a movement load, a size and a weight can be reduced.

Title: Switched capacitor filter
Inventor: MASUDA SHINJI
IPC: H03H19/00
Filed: 1987-12-16
Abstract: PURPOSE:To realize a highly accurate filter by using an output or an adder means as the final output so as to attain low sensitivity. CONSTITUTION:Voltages (V2<1>, V2<2>, V1<3>, V1<4>) at the output side of an SC filter circuit are added sequentially to form a final filter output and the addition including the delay for each period is applied. Thus, the approximation in an input section of the SC filter circuit is compensated and the tight design based on the twin linear conversion as the entire circuit is attained. That is, the input and output sides are replaced in time division to generate two states, the outputs of both the states are added to form the final output of the SC filter circuit. Thus, the worst sensitivity at the zero frequency of the SC filter is made zero to form low sensitivity thereby realizing the highly accurate filter.
