Title: Optical pickup device
Inventor: SUMI TAKESHI
IPC: G11B7/09
Filed: 1988-06-03
Abstract: PURPOSE:To enable tracking servo without having an actuator by providing an objective lens array and optical path parallel moving member arranged in the direction orthogonal with tracks between a polarized beams splitter and an optical recording medium. CONSTITUTION:The spot position by which the tracks of a magneto-optical disk 5 is irradiated is assumed to deviate from the normal O point to the Q point on the left side and a servo optical system is assumed to detect this devia tion as a track error signal. A track control circuit receives this signal and converts the same to an electric signal for obtaining a desired track position. Parallel flat plates 16 are then rotated theta  deg. by a rotating means. The light entering from an incident face 17 moves in parallel to the right, is emitted from an exit face 18 and is focused by a microlens 15 on the right side of the objective lens array 14, by which the light is focused to the normal O point. The device is reduced in cost, size and weight in this way without having the need of objecting the objective lens for tracking servo.

Title: Solid-state image pickup device
Inventor: ARAKAWA KENICHI
IPC: H04N5/335
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption while lowering the power supply voltage by forming the depletion impurity layer of a depletion MOS transistor in the same process as the depletion impurity layer at a reset part thereby decreasing the width of an input pulse to a reset gate. SOLUTION: A D(depletion) transistor T1 and a reset transistor 3 are fabricated in the same process by implanting the same impurities. When the resistance is varied in a region beneath a reset gate electrode due to fluctuation of impurity concentration, the resistance of the D transistor T1 in a voltage divider circuit 17 is varied similarly. Consequently, a potential fluctuation beneath the reset gate electrode is also fed back to the voltage divider circuit 17. According to the arrangement, current flow of the transistor T1 in the voltage divider circuit 17 is varied such that a reset voltage VRS is varied in the direction for canceling the potential fluctuation beneath the reset gate when the impurity concentration beneath the reset gate is varied.

Filed: 1981-09-01
Abstract: PURPOSE:To prevent shifts of position of a track caused in heat treatment, by providing a laser welding part through the irradiation of a laser light to a part  of a pair of core block halves. CONSTITUTION:A small rigid part 6 consisting of projections 6a, 6b is formed at one end of core block halves 1a' and 1b'. The halves 1a' and 1b' are brought into abutment on each other via a gap restricting spacer 4 at the upper part of both ends of the halves and via low-melting point oxide glass 5 as a bonding member at the lower part. A welding part 7 is formed by radiating a laser light to the center near the tip of the part 6 and the projections 6a, 6b are welded. Next, heat treatment is performed by applying a pressure to the arrows F, F' vertical to both sides of the core blocks. Thus, the glass 5 is welded and track width restricting grooves 3a, 3b are bent to the arrows B, B'. No track position shift is caused in the direction of the arrows A, A', because the rigidity of the part 6 is large.

Title: Charging circuit system and charger
Inventor: MITSUOKA TERUYOSHI
IPC: H02J7/10
Filed: 1992-04-30
Abstract: PURPOSE:To improve charging efficiency, and to reduce heat generation by controlling the input voltage of a current control circuit or a charging circuit according to the cell charging voltage and preventing the generation of voltage difference more than required. CONSTITUTION:When the terminal voltage of a cell 104 is constant voltage or lower, supply voltage to a charging circuit 102 is kept constant by a conventional method. When the cell voltage rises and the input/output potential difference of a constant-current generation circuit 103 monitored in a potential difference detector 106 reaches a value lower than a fixed value, a voltage detector 12 is controlled by a voltage control signal, and the output from a switching type constant-voltage generation circuit 1 is controlled so that the input/output potential difference of the constant-current generation circuit 103 is kept at the fixed value. When the output from the switching type constant-voltage generation circuit 1 is controlled in this manner, the input/output potential difference of the constant-current generation circuit 103 of the charging circuit 102 can be reduced at all times while supply currents to the battery are kept constant. Accordingly, power consumption in the circuit is curtailed, and a calorific value can be lowered.

IPC: G03C5/31
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a silver halide photographic sensitive material having superior aptitude to detection of an infrared sensor without lowering aptitude to low replenishing processing and rapid processing, without occurrence of image detects such as haze by controlling an amount of total coated silver and light transmittance and reflectance each into a specified range. SOLUTION: An emulsion layer formed on a transparent support contains flat silver halide grains having an aspect ratio of 2-20 and occupying >=50% of the projection areas of the total silver halide grains and a total silver coated amount is 1.0-3.3 g/m<2> and a light transmittance is 10-35% and a light reflectance of 40-60% in the wavelength region of 950 nm. If the silver amount is >3.3 g/m<2> , an aptitude to detection of the infrared sensor is lost, and if <1.0 g/m<2> , a maximum density is too low to be used for the detector. If the transmittance of the 950 nm light is >35%, or the reflectance is <40%, the aptitude of the sensor is lost and if the transmittance is <10%, or the reflectance is >60%, it is difficult to design the photosensitive material.
