Title: Disk shaped recording medium
Inventor: YAMAGAMI TAMOTSU
IPC: G11B7/24082
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent a broadwise displacement of a groove from giving adverse effect on reproduction of recording data by displacing a track of a recording medium in the broadwise direction for a period of an integer multiple of a period of a channel clock. SOLUTION: Each groove 1 of a magneto-optical disk is in advance displaced in the broadwise direction for a frame period of (22T×2+17T×32), where T is a channel clock period. The period 22T is used for a frame synchronizing signal and the period 17T is used for clock generating and synchronizing signal locking information. In the case of recording data to the groove 1, a frame synchronizing signal, a sub code and connection bits before and after of it are recorded and data are recorded so that an edge 1a of the groove 1 and an edge 1b of the connection bit are in matching with each other in a data and parity recording area. Thus, the circuit configuration of an equipment is simplified and the frame synchronizing signal is surely detected.

Title: Semiconductor relay
Inventor: SATSUTE TOYOFUMI
IPC: H03K17/08
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To interrupt drain current for not less than prescribed current with high reliability by setting a thyristor in a state where drain current exceeds prescribed current and current flows from an anode to a cathode. SOLUTION: The optical trigger thyristor 4 is set in the state where drain current exceeds prescribed current, it flows and therefore current can flow from the anode to the cathode. A charge charged between the gate and the source of MOSFET 3 flows from the anode to the cathode and the drain and the source of MOSFET 3 become the interrupted state. Since current which once flows from the anode to the cathode continuously flows as long as photovoltaic power is applied between the anode and the cathode even if drain current of MOSFET 3 exceeds prescribed current and it does not flow, the gate and the source of MOSFET 3 are not charged. Thus, the interruption state and the conduction state of MOSFET 3 are prevented from repeating.

Abstract: PROBLEM TO BE SOLVED: To correct the non-uniformity of luminance distribution caused by the deviation of a converging position in a projecting lens on a relay optical path by strengthening the aberration out of an optical axis while using a specified first relay lens, and moving the real converging position of illumination light flux from a calculated focal position corresponding to the aberration. SOLUTION: The light flux in the respective colors of R, G and B is respectively transmitted through a video display device composed of two ordinary optical paths and one relay optical path 2c, and images on a video display device are synthesized as a full color image by a cross dischroic prism 1. The difference of optical path lengths between the ordinary optical path and the relay optical path is corrected by relay lenses 4 and 5 arranged on the relay optical path. Between these lenses, the low refraction factor material having refraction factor of about 1.5 to 1.65, the focal distance of about 40 to 60 mm and the double convex form where the ratio of curvature radius between front and rear surfaces is about 1:2 to 1:3 are adopted as the first relay lens 4 so that the aberration out of the optical axis can be reinforced.  Corresponding to that aberration, the practical converging position of illumination light flux is moved from the calculated focal position.

IPC: F27D21/00
Filed: 1990-01-26
Abstract: PURPOSE:To highly accurately execute temperature control by setting up the set heating temperature of a black body as the objective heating temperature of the surface of an object and controlling an object heating means so that the detecting temperature of a radiation thermometer coincides with the set heating temperature. CONSTITUTION:A base 1 on which a thin film 2 to be an object whose temperature is to be controlled is to be formed is arranged on the upper part of a vapor deposition source 5 consisting of a crucible 3 a material for vapor deposition 4 and heated by the object heating means 6 such as an electric heater at the prescribed temperature. When the temperature T'o of the vapor deposited thin film 2 of the base 1 is less than the objective heating temperature To, radiation energy Ein made incident upon the radiation thermometer 7 is smaller than the radiation energy E(To) of the black body 8 of To, i.e. T'o<To. When the temperature T'o is higher than the temperature To, the energy Ein is larger than the energy E(To), i.e. T'o>To. Thereby, the necessity of heating of the thin film 2 can be judged by comparing both the values T'o, To and the output of the means 6 is controlled so that T'o = To, so that the temperature To of the thin film 2 can be controlled independently of a change in the radiation rate of the thin film 2.

Title: Electric laminated board provided with ultraviolet ray absorptive capability
Inventor: TAKE MORIO
IPC: H05K1/03
Filed: 1989-01-27
Abstract: PURPOSE:To effectively absorb an ultraviolet ray by mixing a specific amount of an optical initiation assistant used for ultraviolet ray curable resin with thermosetting resin. CONSTITUTION:0.1-6.0wt.% of optical initiation assistant to be used for ultraviolet ray curable resin is mixed with thermosetting resin. If the optical polymerization initiation additive of the ultraviolet ray curable resin contains both optical initiation assistant and optical initiator, it is most efficient to employ entirely the same optical initiation assistant and optical initiator as those used for the resist to prevent an unexposed part from photosensing due to optical transmission. Thus, in both the case that an ultraviolet ray of long wavelength is used to be exposed and the case that a long exposure time is provided with large exposure light amount of a photoresist, there is no fear that the unexposed part is photosensed, thereby particularly efficiently absorbing the light of the wavelength for the resist-exposure.

Abstract: PURPOSE:To enable even high frequency signal whose distances from transponders are discrete and whose level widely changes to be received without saturation or missing by providing as many low noise amplifiers as the number of the transponders that perform transmission and reception. CONSTITUTION:A receiver is composed of an antenna 1, changeover units 2 and 5, low noise amplifiers 3-1, 3-2,...3-N, AGC circuits 4-1, 4-2,...4-N, a mixer 6, a local oscillator 7, an intermediate frequency amplifier 8 and a demodulator 10. High frequency signals inputted to the antenna 1 are selected by the changeover unit 2 so as to be inputted to the low noise amplifiers 3-1, 3-2,...3-N corresponding to transmitting transponders, controlled with gains and amplified in the corresponding AGC circuits 4-1, 4-2,...4-N, transmitted through the changeover unit 5, frequency-converted, intermediate-frequency-amplified and demodulated. Thus, since the input levels of the low noise amplifiers do not widely change, the receiver has function capable of normally receiving even when the time constants of AGC circuits 4-1, 4-2,...4-N are large.
