Title: Charge subtracting device
Inventor: KONDO KAZUO
IPC: H01L29/76
Filed: 1986-07-29
Abstract: PURPOSE:To obtain the result of subtraction of a 1st signal charge from a 2nd signal charge on a 3rd charge transfer channel by feeding back a comparator output to a gate electrode. CONSTITUTION:In impressing a voltage v1 to a noninverting input of a comparator 17 and a voltage v2 to an inverting input, an output of the comparator 17 goes to a high level and the level of the gate arranged on the 3rd transfer channel 21 adjacent to a 2nd diffusion layer goes to a high level. In impressing a high voltage to the gate, a channel potential beneath the gate electrode goes to a high level and electrons in a 1st diffusion layer override the channel potential and goes to adjacent potential well. Since the entire system forms a negative feedback, the stable point is obtained when the potential v1 of the 1st diffusion layer is equal to the potential v2 of the 2nd diffusion layer. The residual electric charge in the 2nd diffusion layer is equal to the electric charge QB in the 1st diffusion layer with v2=v1. Thus, the electric charge flowing from the 2nd diffusion layer to the adjacent potential well is expressed as (QA-QB) and the subtraction between the transferred charges is executed.

Title: Molding method
Inventor: YAMAKAWA KAZUHIKO
IPC: B60R21/20
Filed: 1992-07-03
Abstract: PURPOSE:To enhance production efficiency at the time of the molding of a module cover or lid. CONSTITUTION:First split molds 34, 36 and a second split mold 38 are combined and an inner layer 30 is formed between both of them by injection molding. At this time, a protruding part 40 is provided to the core surface of the base end side of the attaching piece 20 of the first split mold 34. Since the inner layer 30 is restricted by the protruding part 40 when the second split mold 38 is separated from the first split molds 34, 36 after the inner layer 30 is molded, the shift of the inner layer 30 is prevented. Even when the inner layer 30 is bonded to the second split mold 38 to be ready to separate from the first split molds 34, 36, the stress at this time is eliminated by the engagement of the protruding part 40 with a recessed hole 28 and force is not almost applied to the part of a tear line 26. Therefore, it is certainly prevented that the attaching piece 20 is divided at the part of the tear line 26. By this constitution, the production of a module cover or lid made of a synthetic resin is markedly enhanced.

Title: Optical head
Inventor: HIGASHIURA KAZUO
IPC: G11B7/135
Filed: 1992-07-03
Abstract: PURPOSE:To realize a novel optical head for optical tape in which focusing or tracking control is not susceptible to centrifugal force and information can be reproduced and/or written at high rate. CONSTITUTION:An optical tape T is wound spirally around the outer peripheral face of a hollow cylindrical optical tape guide 22 and guided and the light from a light source 10 is condensed through a condenser lens no to a position p close to the mirror race or a rotary mirror 18. Light flux reflected on the rotary mirror 18 is condensed on the optical tape T by means of an objective lens 20 rotating together with the rotary mirror 18 through the optical tape guide 22. Returning light flux reflected on the optical tape T is separated through a light flux separating means 14 into light receiving section 24, 26, 28 sides thus producing a signal containing a focusing error signal and a tracking error signal. Based on these error signals, a servo mechanism 30 shifts the condenser lens 16 in the direction of optical axis and the direction perpendicular thereto thus performing focusing control and tracking control.

Title: Semiconductor laser for integrated optical heterodyne
Inventor: FUJITA TOSHIHIRO
IPC: H01S5/00
Filed: 1982-10-07
Abstract: PURPOSE:To obtain a semiconductor laser capable of reducing the coupling loss to a transmission line or detector without necessity of independently preparing two types of lasers with hardly receiving the effect of frequency variation due to temperature change by providing a frequency modulating semiconductor laser and a local oscillator semiconductor laser on the same substrate and substantially equalizing the oscillating wavelengths to each other. CONSTITUTION:The oscillating frequencies of laser lights 12, 13 from semiconductor lasers 10, 11 grown on the same substrate are similar to each other. When a current source 14 is used as a modulation signal source and a current source 15 is used as a local oscillator, a light source for optical heterodyne can be prepared. The adjustments of the frequencies can be performed by the injected current amounts from the sources 14, 15, and the oscillating frequency change due to variation in the resonator length can be, for example, cancelled due to the same place. In addition, the coupling loss at the detector is not necessarily considered by combining the signal light and the local oscillation light by the semiconductor laser at the transmitter side.

Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To access precisely a target position without being affected by an adverse effect due to displacement of an objective lens by widening a response band of a thread servo in an access mode. SOLUTION: When the instruction of the access mode is imparted to a CPU 38 from a host, the CPU 38 imparts the instruction widening the response band of a transfer servo (thread servo) than the time at a reproducing mode time to a control circuit 40. That is, the control circuit 40 controls a gain adjustment circuit 32 according to the instruction from the CPU 38, and enlarges an output gain of a thread control circuit 30 than the time at the reproducing mode time. Thus, the response band of the thread servo is widened, and following ability of a thread is enhanced. Then, when a pickup arrives at a track that a target position exists, the access mode is ended according to the instruction of the CPU 38, and tracking is applied.

Abstract: PURPOSE:To inform a timing to which an abnormal operation is produced to the outside without providing any special circuit, by utilizing some of the address signals transmitted from a CPU as a trigger signal for the start of investigation of the abnormality when the abnormal operation occurs. CONSTITUTION:The highest order bit ADR15 of an address bus 12 consisting of address signal lines ADR0-15 of 16 bits is sent to a trigger signal buffer 23. Then the output of the buffer 23 can be taken to outside directly as a trigger signal. While the program of a working abnormality detecting part 20 is executed by a CPU 10. The control is shifted to a restoring part 22 by a trigger generating part 21 when the abnormality is detected. The part 22 delivers an instruction for the reset to an original program area. Here the highest order bit of the bus 12 is changed by the address signal transmitted from the CPU 10 for the fetching of the instruction. Thus the trigger signal is delivered from the buffer 23.
