Title: Dc/dc converter
Inventor: HONDA SHIGERU
IPC: G05F1/573
Filed: 1994-03-11
Abstract: PURPOSE:To protect a switching means from excessive current caused by a short-circuited load by switching the supply source of a power supply voltage to a control means from the input side to the output side with a time limit device and a change-over means after a DC/DC converter starts up. CONSTITUTION:The supply source of a power supply voltage to a control means 103 is changed from the input side to the output side of a DC/DC converter after the specified time from the start of the supply of an input voltage by the operations of a time limit means 112 and a change-over means 111. Therefore, when a load or the like, which is connected to the output side, is short- circuited and the output voltage is decreased, the supply of the power supply voltage to the control means 103 is stopped. Thus, the control signal to a switching means 101 becomes open. The switching means 101 becomes OFF in correspondence with the opened state. Therefore, the excessive current caused by the short-circuited load does not flow into the switching means 101, and overheat trouble can be positively prevented.

Title: On-track detector
Inventor: TATEISHI KIYOSHI
IPC: G11B7/085
Filed: 1989-02-20
Abstract: PURPOSE:To suppress the noise included in a reflected light quantity signal to considerably improve the on-track detection precision by discriminating the level through a low-cut filter after cutting the level of the reflected light quantity signal. CONSTITUTION:When a focus sum signal B includes noise areas (a), (b), and (c) due to pit shape change, disk flaws, and pit drop-out, a clip circuit 20 clips the output of an amplifier 8 by a prescribed level, and outputs a signal C where the level rise of a part higher than the on-track state level of the signal B is suppressed. A low-cut filter 9 eliminates the low-band component of the signal C to output a signal D where the noise component of the area (c) is reduced. An LPF 23 eliminates a high-band component in the signal D to suppress the noise of the area (b) and outputs a signal E where the phase advance due to the filter 9 is restored. A signal E where the generation timing of an on-track signal is accurate is inputted to a comparator 10 to generate an accurate level discrimination output F which goes to the low level at the time of the on-track state.

Title: Photosensitive material
Inventor: KAKIMI FUJIO
IPC: G03F7/00
Filed: 1988-02-24
Abstract: PURPOSE:To make the photosensitive material easily peelable from an image receiving material by incorporating a water-proof binder in the external part of a microcapsule which constitutes a photosensitive layer. CONSTITUTION:The water-proof binder is incorporated in the microcapsule of the photosensitive layer. The water-proof binder is composed of a combination of a hydrophobic polymer and a reaction product of polyvinyl alcohol or its modified material and a crosslinking agent. The binder is useful for forming the continuous layer of the capsules by fixing the capsules with each other and for improving the sticking strength between the capsule and a supporting body. And, the binder does not cause a softening and a floating, even under high temp. and humidity conditions. Thus, the peeling operation between the photosensitive material and the image receiving material after transferring an image to the image receiving material, can be easily carried out by a relatively small force.

Title: Optical bill counter
Inventor: KAMEI MANABU
IPC: G07D9/04
Filed: 1985-03-05
Abstract: PURPOSE:To adjust the light of an optical sensor automatically even if its sensitivity varies owing to oscillation in transportation, a secular change, etc., and to prevent malfunction by holding the light emission level of a light emitting element invariably constant by a photodetection signal decision means and a light emission level adjusting means. CONSTITUTION:This dimming processing is performed at every start of bill counter operation and an output gear is rotated after the dimming is completed to perform counting operation. when the dimming processing is started, the light emission level of the light emitting element 6a is set to a minimum value. Then, photodetection signal level data Lr(a) is read in so as to know a photodetection state of a photodetecting element 5a in this state, thereby deciding whether this read photodetection level data Lr(a) is a reference level, e.g. '8' or not. When the photodetection signal level data Lr(a) is smaller than '8', the light emission level data Lt(a) is increased by one stage to increases the quantity of light emission of a light emitting element 6a by a specific quantity. Then while the quantity of light emission is increased, a large/small decision on the photodetection signal level Lr(a) is made again. This processing is repeated until the photodetection signal level Lr(a) reaches '8'.
