Title: Moving object detecting device
Inventor: HASHIMOTO NORIYOSHI
IPC: G01B11/00
Filed: 1979-04-21
Abstract: PURPOSE: To detect the timing of passing of the optical image over the measuring point easily, by detecting the address by scanning just before and after the optical image passes over the measuring point, from the address of the element in which the optical image is positioned on every scanning and the measuring point address.  
     CONSTITUTION: On every scanning of a photoelectric element array sensor 4, the address of a photoelectric element in which the optical image of a moving object is positioned is detected, and the first and second detection addresses by scanning just before and after the optical image passes over the measuring point are obtained from said detection address and measuring point address. From these first and second detection addresses, the time when the optical image passes over the measuring point is calculated. For example, the edges of the front curtain 3b and a rear curtain 3d of the focal plane shutter 3 are detected in circuits 8W12 through the sensor 4, and the number of times of scanning is calculated in a counter 17, and said calculations are performed in calculation means 26W28 through shift registers 14, 15, memories 18, 19, etc., so that the shutter speed is measured.

Title: Method for measuring noise index
Inventor: AIDA KAZUO
IPC: H04B10/40
Filed: 1995-03-08
Abstract: PURPOSE: To make it possible to easily measure the characteristic of an optical amplifier for optical communication with high accuracy by separating and detecting the output photoelectric power of a passive optical element and calculating a leakage characteristic. CONSTITUTION: A modulation signal generating section 4 of 1MHz executes modulation by outputs Q and -Q varying in phase by 180 deg. and an electro-optical converter 2 executes modulation by the output Q to obtain input light (3). This input light (3) is inputted to the passive optical element 11 and its output is inputted to an optical switch 3. The optical switch 3 is driven by the output -Q from the modulation signal generating section 4. The output photoelectric power (Pout) of the passive optical element 11 synchronized with certain time region of the light pulse signal from this optical switch 3 and the output photoelectric power (Pleakage) of the passive optical element 11 synchronized with the time region having no light pulse signals are separated and detected. The leakage characteristic (ISO) is calculated by equation IOS=Pleakage/Pout.

Title: Magneto-optical head
Inventor: TAKEKOSHI TARO
IPC: G11B11/105
Filed: 1995-03-08
Abstract: PURPOSE: To prevent the offset of a track error signal by mounting a laser beam source, objective lens, photodetector, optical branching element and polarization beam splitter on the moving part of an actuator. CONSTITUTION: A hologram optical head 20, the polarization beam splitter 40 and the objective lens 60 are mounted in the moving part 10 of the actuator and are integrally driven. As the result, optical axis misalignment occurs less than in the conventional method of driving only the objective lens and particularly the offset of a track error signal does not occur. The aberration deterioration and power loss of the optical system by the optical axis misalignment are averted. Consequently, the quality of the error signal is stabilized and the quality of the light emitted from the objective lens 60 is stabilized.

Filed: 1986-03-06
Abstract: PURPOSE:To enable sealing without unevenness to be performed, by cutting an indium inner plate one side by one side to be used in a symmetrical shape so that a cut surface without unevenness can be made. CONSTITUTION:Indium 7 in an indium ring is cut one side by one side. Thus, scraps cut 7a are extruded in the side-plane direction, automatically removed without adhering to a cut plane. Without requiring to draw out the scraps cut 7a therefore, the cutting becomes easy, without skillfulness in doing. And, because a blade part 30a of a cutting tool 30 is made not in a hollow shape but in a simple one in which one side is opened, manufacture of the cutting tool 30 becomes easy, available for processing with high precision. Therefore, a cut plane without unevenness can be made. Besides, without the scraps cut 7a being extruded separate in two directions, the amount of cutting the indium 7 by the cutting tool 30 becomes decreased to make the cut surface without unevenness. Therefore, sealing without unevenness can be performed.

Title: Semiconductor device
Inventor: HAGINO HIROYASU
IPC: H01L29/78
Filed: 1987-03-03
Abstract: PURPOSE:To lower fraction defective due to a short circuit between a gate and a source by dividing a source-electrode connecting section into several or several dozen small groups. CONSTITUTION:A source electrode 28 is divided into ten MOS unit groups. Separate MOS unit group consists of ten thousand unit cells. The source electrodes 28 in each MOS unit group are partitioned individually, and the source electrodes 28 in separate MOS unit group are connected to the outside through a method such as wire bonding. Wires 30 for wire honding represent wires extracted to external electrode terminals from respective MOS unit group and Au and Al are used as the wires 30, but an Al wire is employed generally from the aspect of cost because phi300-phi400mum are required on large currents. It is preferable that the scale of the MOS unit groups is divided to the scale of the wire capacity of the Al wires from the point of view of simplification at the time of assembly. An allowable current value at every one of the Al wires takes approximately 12A when the Al wires having phi400mum are used, thus resulting in 12A in one MOS unit group.

Abstract: PURPOSE:To realize compact structure by disengaging a clutch for coupling between a parking brake and drive means through a release spring made of shape memory alloy while controlling heating of said spring. CONSTITUTION:A pulley 23 to be wound with a wire 14b coupled to a parking brake and a rotary motor 21 for functioning/disabling the parking brake are coupled/interrupted through clutch members 22d, 23a. Upon fault of motor 21 under operating condition of parking brake through coupling of clutch members 22d, 23a, the parking brake is never released automatically. Here, power is fed to release spring 25 to heat it. Since said spring 25 is made of shape memory alloy, spring force is increased upon heating to setting temperature. Consequently, the clutch member 23a is pushed up through the shaft 22a to be uncoupled thus to release braking.

Abstract: PROBLEM TO BE SOLVED: To reduce a bit length jitter by incorporating tricyanovinyl compound represented by a specific formula in an organic coloring matter layer, thereby forming an infinitesimal recorded part having almost no rim. SOLUTION: A polycarbonate board having a diameter of 120mm and a thickness of 1.2mm and a tracking groove is coated with organic dye solution by a spin coating method. Then, gold is film formed on the dye layer so that mean thickness becomes 100nm by a DC magnetron sputtering method to form a light reflecting layer. Here, tricyanovinyl compound represented by a formula (where R<1> , R<2> indicate alkyl group, alkenyl group, cycloalkyl group or aryl group which may be independently substituted or R<1> and R<2> are bonded, or R<1> and R<3> are bonded to form a heterocycle) is incorporated in the dye layer. Thus, bit length jitter can be reduced, and it can be applied to a short wave recording of a wavelength of 620 to 690nm.
