Title: Magneto-optical recording method
Inventor: OSATO YOICHI
IPC: G11B11/10
Filed: 1987-03-10
Abstract: PURPOSE:To realize overwrite, by using a magnetic layer of double construction as a magneto-optical recording medium, and performing recording with a binary laser power by specifying relation between the coercive force of first magnetic layer and a magnetic field. CONSTITUTION:A device is constituted in such a way that the first magnetic layer 2 and second magnetic layer 3 are laminated on a transmissive substrate 1. The relation such as (HH>HL>sigmaw/2Msh) is required among the coercive forces HH and HL of both magnetic layers, the saturation magnetization Ms and the film thickness (h) of the second magnetic layer 3, and magnetic wall energy sigmaw between two magnetic layers. When a laser beam having two kinds of laser power is projected on a disk plane, a magneto-optical effect supplied from the first magnetic layer 2 is used mainly in reproduction, and the second magnetic layer 3 plays an important role in recording. In such a way, it is possible not only to obtain a recording method capable of performing the overwrite, but to reproduce a recorded signal extending over a long period.

Title: Semiconductor radiation detecting device
IPC: H01L31/09
Filed: 1992-03-12
Abstract: PURPOSE:To reduce IR drop at a boron film part by lowering resistivity of the boron film through doping of impurities. CONSTITUTION:A boron film 4 contains a high-concentrated 10B of low resistivity obtained from doping of impurities. Since, by that, electric resistance in the thickness direction of the boron film containing B can be lowered, the IR drop at the boron film part caused by the leakage current occurring at a joint part can be reduced, so, required voltage can be applied to the joint part. <10>B concentration of 80% or higher is enough for practical use. Further, a boron film 41 having been formed into an N-type one by doping with impurities is coated on a P-type silicon substrate 11 to form a heterojunction between the substrate 11 and a P-type substrate 1. As a result, neither a P layer 2 nor N<+> layer is required to be formed, and therefore occurrence of non-sensitive layer is prevented.

Title: Color recognizing device
Inventor: FUJIMOTO JIYOUJI
IPC: G01J3/00
Filed: 1984-03-19
Abstract: PURPOSE:To obtain the effect of the judgment of discoloration of medicine, which is useful in manufacturing lines, accurately and quickly, by judging the difference in phase times of a carrier color signal and subcarrier signals, which are photographed by a color TV camera, with a color judging trigger pulse signal. CONSTITUTION:A reference trigger signal, which is formed by a carrier-wave phase trigger circuit 3, is delayed by a preset time, and a trigger pulse signal from a color-judging trigger pulse circuit 4 is sent to a gate circuit 6. Thus a gate is opened. When a carrier color signal, whose phase difference is the same as that of a preset time, is present, the carrier color signal is transmitted to a color-recognition output circuit 7 through the gate circuit 6. A signal is sent out of the color-recognition output circuit 7. When the color of a body to be examined is changed, the timing of the trigger pulse signal of the carrier-color signal trigger pulse circuit 4 is deviated. Therefore, the signal is not transmitted to the color-recognition output circuit 7, and the signal is not outputted to the outside.

Abstract: PURPOSE:To achieve improved reliability by using polyisobutylene denatured polyethylene whose major infrared ray characteristic absorption bands are about 720cm<-1>, 730cm<-1>, 924cm<-1>, etc., as a sealing material. CONSTITUTION:Polyisobutylene denatured polyethylene whose major infrared ray characteristic absorption bands are about 720cm<-1>, 730cm<-1>, 924cm<-1>, 951cm<-1>, 1231cm<-1>, 1367cm<-1>, 1390cm<-1>, 1463cm<-1>, 1794cm<-1>, 2019cm<-1>, 2346cm<-1>, 2850cm<-1> and 2922cm<-1> is used as a sealing material. For example, polyisobutylene denatured polyethylene is thermally deposited on a peripheral portion of one side of a positive-pole terminal plate 5 and a negative-pole terminal plate 1, both made from stainless steel plate. Then, after a sheet-like lithium negative pole 2, a separator 3 and a sheet-like positive pole depolarizing mix 4 are stacked up in layers on the face of the negative-pole terminal plate 1, the positive-pole terminal plate 5 is placed on top of them and the sealing material is thermally deposited by applying heat and pressure to its peripheral portion. In this manner, it is possible to ensure no deterioration in air-tightness of the battery even under high-temperature storing condition with stabilized battery performance.

IPC: H02P6/06
Filed: 1995-02-17
Abstract: PURPOSE: To detect the rotor position accurately regardless of the load and to realize optimal conduction switching of the armature winding. CONSTITUTION: When a DC power supply is switched at an inverter section 4 in order to apply a voltage to the armature winding of a brushless motor 3, the inverter section 4 is driven based on the detected rotor position of the brushless motor 3 to switch conduction of the armature winding. In such a control method for the brushless motor, a comparison circuit 10a compares the terminal voltage (induced voltage) of the armature winding with a reference voltage and delivers a position signal (e) variable at an intersection determined by the comparison results to a control circuit 11. The control circuit 11 calculates the times corresponding to predetermined phase angles ((300-α) deg., (90-α) deg., (150-α) deg. or a table data) from the variation point of the position signal (e).  Furthermore, the calculation times (the times corresponding to ((30-α) deg., (90-α) deg., (150-α) deg.) are measured and conduction of the armature winding of the brushless motor 3 is switched at the end of time measurement.

Abstract: PURPOSE:To indicate contactlessly, reduce a driving motor at its size and perform the display of an indicator and recording independently by making heat sensitive and optical sensors on heat generating and light emitting element groups sensitive to the operation of the elements and moving the sensors. CONSTITUTION:A multielement bar graph 7 is driven by a micro-processor 1 and a positional element 7a corresponding to the process input value of an AD converter 61 is selected to perform heat generation and light emitting. Simultaneously with said operation, a processor drives a motor 2 to change the position of a sensor 8, retrieves a heat sensitive point and a photodetective point from the sensor output values obtained from an AD converter 62 and positions the sensor 8 on a peak point of the sensor output. An indicator is fitted to the sensor 8, and if necessary, the indicator is directly connected or followed. Since the sensor 8 and the indicator are only guided by the bar graph 7 and are contactless with it, the driving force of the motor 2 can be reduced and the size can be also reduced.
