Title: Optical card
Inventor: MAEDA SHUICHI
IPC: G11B7/24012
Filed: 1988-06-28
Abstract: PURPOSE:To obtain a DRAW type optical card having a single plate structure and good recording sensitivity even when recording is performed by pitting or deforming the recording layer by laminating successively the recording layer comprising an organic coloring compd., middle layer of specific conditions and surface protective layer of specific conditions on a substrate. CONSTITUTION:The optical card in which informations are recorded by forming pits or deformation part with laser beam irradiation has layers of the recording layer comprising an organic coloring compd., the middle layer having <=100kgf/ cm<2> 100% tensile stress specified by JIS K 6301, and the surface protective layer having hardness of H or above by the pencil scratch test specified by JIS K 5400, deposited on the substrate in this order. Namely, by providing the middle layer of low elastic modulus, the DRAW type optical card of a single plate structure having good recording sensitivity can be obtained. By introducing this middle layer, the influence of the surface protective layer on the recording sensitivity can be ignored, so that a material of high hardness can be used for the surface protective layer. Thereby, recording sensitivity is largely improved and an optical card with high sensitivity and single plate structure can be obtained.

Abstract: PURPOSE: To retrieve desirable information at a high speed with high precision from information recorded at high density, by detecting a relative moving amount between a recording disk and pickup and its direction and by performing the arithmetic process of the moving amount and the address on the recording track on the disk.  
     CONSTITUTION: Picture information recorded on recording disk 3 is detected by pickup unit 4 with reflected light of beam 2 from light source 1 such as a laser, and unit 4 generates a pulse equivalent to the moving amount relative to disc 3. The output of unit 4 is inputted to movement detection circuit 11 which detects the moving amount and direction and address reader 13 which reads out the address of information under regeneration. The address of the desirable information is inputted to input unit 12 and output signal A of unit 12 and the output of unit 13 are processed by arithmetic unit 14 to obtain a preset value, which is inputted to up-down counter 15. The value counted from signals relating the moving amount and the direction from circuit 11 and the preset value in counter 15 is D/A-converted 16 and pickup driving element 18 is driven to retrieve the desirable information.

Title: Semiconductor memory
Inventor: ISHIKAWA TORU
IPC: G11C11/409
Filed: 1991-07-02
Abstract: PURPOSE:To reduce the size of a memory control circuit by changing a timing signal into a one-shot precharge system through a delay circuit. CONSTITUTION:In a one-shot precharge system, a switch signal SW is set at a high level and a delayed memory activation signal EN is selected by a selector 2 as an internal signal IEN. An AND gate G1 of a timing signal changing circuit 4 is kept at a low level when the signal EN is kept at a high level. Meanwhile the prescharge signal PE applied to a memory cell array part 1 and a sense amplifier activation signal SA are fixed at a low level and a high level respectively. Then the fixed levels of both signals PE and SA are released when the signal EN is set at a low level and then synchronized with a precharge signal PEn and a sense amplifier activation signal SAn respectively. Thus no through current flows in a precharging state and therefore the size of a memory control circuit is reduced.

Title: Vane pump or motor
Inventor: ICHII YOUICHI
IPC: F04C2/344
Filed: 1980-11-15
Abstract: PURPOSE:To reduce power loss or wear out by forming an apporoximately oval- shaped cylinder chamber so that an arc-shaped vane may make a sliding motion to the inside wall surface of the cylinder chamber by a contact pressure balance irrespective of a rotary angle position of a rotor. CONSTITUTION:A cylinder chamber 2 is approximately oval-shaped in outside appearance so that the end of an arc vane 6 may come into constant contact with the inside wall surface of the cylinder chamber 2 in no matter where a rotary angle a rotor 4 is located. With this construction, a sliding motion of the arc vane 6 is accomplished by a contact pressure balance which allows the ends of the vane 6 to come into relative contact with the inside wall surface of the cylinder chamber 2. As a result, the contact pressure exerted to the wall surface inside a cylinder 1 at the ends of the arc vane 6 and the air-tightness produced by the contact pressure can be equally maintained and are not subjected by the cahnges in rotary angle position of the rotor 4 or the rotary speed, thereby reducing power loss or wear out. Therefore, a high capacity can be exerted as a vacuum pump or fluid pump.
