Title: Semiconductor integrated circuit
Inventor: YOSHINAGA MAKI
IPC: G11B5/02
Filed: 1985-01-25
Abstract: PURPOSE:To prevent deterioration in abnormality detection margin by providing a constant current source separately with a head driving part and a current path of the same constitution with a current path from the circuit in front of the head driving part to the constant current source. CONSTITUTION:The head driving part and current path of the same constitution with the current path from the circuit in front of it to the constant current source which flows a write current to the head driving part to the constant current source are connected to the constant current source. A current proportional to the write current of the head driving part is flowed from the constant current source to the 2nd current path to generate a voltage having the potential as or constant potential difference from the potential at the output terminal of the head driving part, thus generating a reference voltage for abnormality detection. Consequently, the reference voltage varies having the same tendency with the potential at the output terminal of the head driving part which varies when the current flowed to the head driving part by the constant current sour- ceis adjusted according to characteristics of a head and the margin when abnor- mality such as the wire breaking of the head is detected does not decreases.

Title: Stereoscopic exposure method and its device
Inventor: UEISHI YUKIHIRO
IPC: G03F1/76
Filed: 1989-01-20
Abstract: PURPOSE:To eliminate the need of skillfulness and time in preparation work, to reduce exposure time and to improve work efficiency by moving a work in relation to an optical unit along a second optical axis so as to move sequentially from a first to a second relative position against a reflecting mirror. CONSTITUTION:The work 38 is moved in relation to the optical unit 32 along the second optical axis Y1-Y2 so as to move sequentially from the first to the second relative position against the reflecting mirror 25. When the work 38 is moved in the first relative position, the shutter 14 of a light source part 20 is opened so that the photosensitive film of the work 38 is exposed to ultraviolet radiation. When the work 38 is moved in the second relative position, the shutter 14 is closed to stop exposure. As a result, the exposure time can be reduced, and the need of the skillfulness and the time in the preparation work is eliminated because exposure work is automated. Efficiency in the exposure work can be thereby improved.

Title: Driving circuit of holeless motor
Inventor: TAKEDA KAZUNORI
IPC: H02P6/21
Filed: 1994-02-03
Abstract: PURPOSE:To start a holeless motor securely by a method wherein, at the first time of the motor start, the motor is driven with the phase switching intervals of the motor driving current supply which are calculated beforehand and, at the second time of the motor start and thereafter, the motor is driven with the corrected phase switching intervals. CONSTITUTION:When a power supply is closed, a processor 4 generates phase switching signals in accordance with phase switching intervals which are stored beforehand and supplied the signals to the ADV terminal of a motor driving controller 5. The period of the phase switching signals supplied to the motor driving controller 5 is successively shortened by the processor 4 in accordance with the stored phase switching intervals and, by repeating the operation, the revolution of a holeless motor 6 is increased. Following the increase of the revolution, counter-electromotive forces which are proportionnal to the revolutions are induced in the respective coils in accordance with the coil positions. Therefore, the counter-electromotive forces which are induced in accordance with the respective coil positions are applied between the terminals G and K, between the terminals H and K and between the terminals J and K of the motor driving controller 5.

Abstract: PURPOSE:To enable normal operation of an engine for a long period by compositely reinforcing a portion around a piston pin hole and through-holes for bolts of a connecting rod made of composite material including aluminum alloy as matrix by the use of silicon carbide whisker with a specified volmetric ratio. CONSTITUTION:In a connecting rod for an internal combustion engine made of composite material including aluminum alloy as matrix, a portion around a piston pin hole 34a, the main body of the connecting rod, and portion around holes 44, 46 for a bolt which fastens and fixes the connecting rods to each other are reinforced by silicon carbide whisker or silicon carbide particle having 30 to 40% of volmetric ratio. A thermal expansion coefficient is thus set to 15 X 10<-6>/ deg.C or lower. As a result, when an engine is operated for a long period under a high load and the temperature of the connecting rod is increased, deterioration of a press-in condition of the piston pin or settling of a seat face around the through-holes for the bolt is prevented.

Filed: 1989-01-20
Abstract: PURPOSE:To make it possible to fully charge a non-aqueous secondary cell safely and reliably by charging the cell under a constant voltage and controlling the charging current when the value of the charging current becomes smaller than a preset value. CONSTITUTION:A supply voltage of AC 100V is supplied to the primary side of a power transformer 2 in an electric source section 1 to output an output voltage from the secondary side, and the collector and the emitter terminals of a transistor 6 in a series regulator 5 are connected to the supply line LV in series respectively. A capacitor 13 is connected between the supply line LV and the ground. A non-aqueous secondary cell 15 is charged under a constant voltage and the charging current is monitored, and when the value of the charging current becomes equal to the preset value of that for the full charge, the charging current is controlled so as to cut off or to switch to normal charge. By controlling the charging current basing on the comparison of the charging current under the fully charged state and the actual charging current as above, the non-aqueous secondary cell 15 can be fully charged safely and reliably.

Title: Solenoid
Inventor: OOTSUKI KATSUMI
IPC: H01H1/24
Filed: 1980-02-06
Abstract: PURPOSE:To prevent breakdown of a spring for step difference absorption due to the suction impact of a plunger by deforming a movable contact point so that the flexible allowance of a spring for step difference absorption may be limited to within a range of tolerable tension and thus minimizing the gap. CONSTITUTION:A movable contact point 18 is installed on a shaft 12 interlocked to the suction action of a plunger, with the same bulge as that of a spring for step difference absorption 15 provided. The movable contact point 18 is provided with an opposite fixed contact point (not illustracted). Normally, however, this fixed contact point is not parallel and is provided with a spring 15 for step difference absorption to eliminate poor contact of the contact point because of the existence of step difference. If the gap B between the spring 15 and the movable contact point 18 becomes wide on account of the suction impact by the plunger, the spring 15 is apt to be broken or lose its repulsive force. However, by fitting the shape of the movable contact point 18 to that of the spring 15, it is possible to minimize the gap and reduce the incidence of breakdown with increased reliability.
