Title: Driving device
Inventor: OKAMOTO YASUHIRO
IPC: H01L41/09
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To make constant the fluctuation of friction force between a fixed friction member and a drive friction member by mounting a plate member with a spring property to the side surface of a gap member with a slightly smaller width than the width of the drive friction member. SOLUTION: In a driving device 28, a drive unit 40 is fitted between two leaf springs 32 of a pinching unit 30, a body part 46a of a drive friction member 46 slides on the leaf springs 32, and the pinching unit 30 consists of a gap member 34, the leaf springs, and a mounting screw 38. Also, the distance between the side surfaces of the gap member 34 is set smaller than the width of a body 46a of the drive friction member 46 by a specific dimension, and friction force is generated between the device part 46a and the leaf springs 32 due to the deflection of the leaf springs 32.  Then, with a dimension for entering the traveling path of the leaf springs 32, friction force can be made nearly constant by making constant the distance between the side surfaces of the gap member 34, thus making constant the fluctuation between the fixed friction member and the drive friction member with a simple configuration.

Inventor: HAYASHI ASAO
IPC: G02B26/12
Filed: 1978-07-10
Abstract: PURPOSE:To achieve higher processing efficiency by a mirror which is a regular polyhedral pyramid having three reflecting faces or a triangular column having two reflecting faces and which rotates about the perpendicular running downward from the vertex down to the base. CONSTITUTION:In the case of recording information, a main body 11 is displaced with respect to two recording media 20a, 20b, whereby auxiliary scanning is accomplished. At the same time, while main scanning is being accomplished by rotating a ratator 15, the parallel luminous flux from a laser light source 21 is modulated with a light modulator 22 and is bisected by a semi-transparent mirror 13. The luminous fluxes are then entered respectively at a scanning angle 60 deg., etc. to a rotary mirror 16 composed of a right triangular pyramid and the reflected luminous fluxes are focussed by objective lenses 18 via reflecting mirrors 17. Next, in the case of reading the recorded information and if the media are of transmission type, the transmitted rays having been focussed on the media 20a, 20b by the lenses 18 are received in  photo detectors 23a, 23b. In the case of reflection type, a beam splitter is disposed  in the optical path between the light source 21 and semi-transparent mirror 13,  whereby the light is processed. Thereby, the recording and reproducing of information may be processed in real time and the efficiency improved.

Title: Sample and hold circuit
Inventor: KOYASU TAKAHISA
IPC: H03M1/12
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To switch sample/hold without using an analog switch and to retain output without being affected by the change in an input signal on holding securely by cutting off the output stage of an operational amplifier by a holding command and by fixing the potential of a capacitor for compensating phase being provided in the operational amplifier. SOLUTION: An operational amplifier OP 3 outputs a signal Vo with the same voltage as an input voltage to a holding capacitor when the switching signal S/H of sample/hold is a high-level sampling. In the case of a holding where the switching signal S/H is at a log level, transistors Tr71 and 72 of a push/pull output circuit 70 are cut off, an output is open-circuited, and the impedance of the side of a differential amplifier 50 of a capacitor C61 for compensating phase is increased by a transistor Tr3, thus preventing the output signal Vo from being changed even if an input voltage is rapidly changed on holding and surely retaining the potential of the holding capacitor.
