Title: Optical information recording and reproducing device
Inventor: TANI NAOAKI
IPC: G11B7/0033
Filed: 1992-08-19
Abstract: PURPOSE:To quickly check the propriety of recording even when the moving direction of a medium is reversed by lighting a position before and after a recording light beam spot with a reproduction light beam spot. CONSTITUTION:A track guide 35 for tracking control is formed in parallel between plural tracks 33 on the recording face of an optical card 8 and data recording pits 34 are formed on the tracks 33. The distance among the recording light spot 30, a zero-th order light slit spot 31 and a 1st diffraction light slit spot 32 by a reproduced light is adjusted by giving a very small angular difference between the optical axis of a recording light and the optical axis of a reproducing light so that a distance L0 between the spot 30 and the spot 31 having a large luminous quantity is made shorter than a distance L1 between the spot 30 and the spot 32. Thus, the propriety of recording is immediately checked even when an optical recording medium is moved reverse by lighting the position before and after the recording light beam spot with the reproduction light beam spot to reduce the effect of the recording light beam spot.

Title: Bellows pump
Inventor: NAKAO YORITO
IPC: F02M37/06
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent generation of twist stress on a bellows so as to prevent reduction of fatigue strength by forming a projection surface part on at least one side of the inner end surface of a guide or a bellows crest part, and abutting them on each other by point contact. SOLUTION: A disk shim 31 is interposed between a bellows crest part 21 and a guide 18. A spherical projection surface part 31a is formed on only one surface of the shim 31, and abuts on a guide inner end surface 18a. The back surface part 31b of the shim 31 is brought into contact with the crest surface of the crest part 21 at a flat surface. Since the guide inner end surface 18a and the shim projection surface part 31a are brought into point contact with each other, rotation of the guide 18 is not transmitted to the bellows crest part 21 even if the guide 18 is rotated by eccentric force from reciprocation driving means by a cam, a wash plate, and the like. Since twist stress is not generated on a bellows main body 20, it is possible to prevent reduction of fatigue strength of the bellows main body 20.

Title: Surface acoustic wave device and lithium niobate monocrystal from which substrate to be used in the same is segmented
Inventor: SAKIYAMA KAZUYUKI
IPC: H03H3/08
Filed: 1988-09-07
Abstract: PURPOSE:To suppress deviation in the frequency amplitude characteristic of a surface acoustic wave device and to improve manufacturing yield by setting the propagation speed of a surface acoustic wave on a free surface at a time when it is propagated on the surface of a substrate within a prescribed range. CONSTITUTION:Assuming the propagation speed of the surface acoustic wave 3 propagating on a rotary Y-cut lithium niobate monocrystal substrate 1 as Vo and distance between electrodes i.e., wavelength 5 as lambda in the surface acoustic wave device using the substrate 1 whose angle of rotation around the X-axis of a crystal axis is set between 125 deg. and 135 deg., it goes to fo=Vo/1. The fo fluctuates by changing Vo or lambda, and Vo receives the influence of dispersion in the width or thickness of a formed electrode or that in the propagation speed Vf proper to the substrate. Especially, since it receives the influence of the propagation speed, the propagation speed is set in a range of 3974.7m/sec-3985.3m/sec by using a photomask, thereby, the deviation in the frequency amplitude characteristic can be suppressed. Thereby, the manufacturing method of the surface acoustic wave device can be simplified and the manufacturing yield can be heightened.

Title: Magnetic recorder
Inventor: SAITOU SHIYUNJI
IPC: G11B5/09
Filed: 1983-11-26
Abstract: PURPOSE:To attain the connection with another controller without changing a control program by actuating an erasion head before conversion by the time larger than the eraser delay time even though a side selection signal is converted after the end of record of a single side. CONSTITUTION:The data is fed to a record input terminal 41 of a recording/reproducing circuit 40 between time points t0 and t2 when the data is recorded with recording/reproducing heads 26a and 26b. Then the data is recorded to a side B by the head 26b. While the data is recorded to a side A when the data is supplied between time points t4 and t6. The side selection (SS) signal (b) given from a CPU which is inverted synchronously with discontinuation of a recordable state of a recordable signal WG' is delayed by a latch circuit 20 by the erasion delay time T of a magnetic head. As a result, erasion heads 18a and 18b work extra by the time T after the recording is over by heads 26a and 26b and at time points t6 and t2. Therefore an unerased track edge never remains. In this way, the interchangeability between magnetic recorders is improved.

Filed: 1986-09-19
Abstract: PURPOSE:To facilitate discrimination, and to reduce cost by the omission of a switch by discriminating 50Hz or 60Hz in a printed substrate from frequency display displayed near a position where components for changing over 50Hz or 60Hz are mounted. CONSTITUTION:In a printed substrate capable of being used in either of 50Hz or 60Hz by exchanging components for a control circuit, a phase-angle determining resistor RA for object frequency 50Hz is fitted at a predetermined position (a lower section lying a little toward the left of the substrate) in the control circuit. The frequency display 1 of 50Hz and 60Hz is set up on a substrate surface, and a resistor RB determining a phase angle for 60Hz is held near 50Hz display in an extractable manner. Accordingly, the printed substrate for 50Hz can be discriminated, thus reducing cost by the omission of a switch.
