Title: Battery residual capacity measuring device
Inventor: SHIBUYA NOBUO
IPC: G01R19/165
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a battery residual capacity measuring device having high input impedance, requiring small power consumption, and capable of sufficiently increasing its measurement accuracy by making the gain of a differential amplifying circuit variable in response to the output of the differential amplifying circuit applied with an offset. SOLUTION: An ASIC 6 is constituted of a current measuring circuit 10, an overcurrent protecting circuit 20, and a power saving circuit 50. A differential amplifier detecting the charging/discharging currents of a secondary battery 1 based on the voltage between both ends of a shunt resistor 2 has high input impedance and high accuracy, thereby the operation of the secondary battery 1 can be surely detected and monitored. The relative measurement accuracy of the current measuring circuit 10 is sufficiently high, the absolute measurement accuracy can be set sufficiently high by the application of an offset to the differential amplifying circuit and the adjustment of its gain, thus the charging/ discharging currents can be measured with high accuracy.  The measurement of the battery residual capacity via the integrating process of the measured current by a microprocessor 5 can be simply made with high accuracy.

Title: Image pickup device
Inventor: KONDO KENICHI
IPC: H04N5/369
Filed: 1988-11-30
Abstract: PURPOSE:To reduce the number of clock pulses and to lower hot hole type dark current by impressing the clock impressed on a gate to eliminate excess charge through electron-hole recombination from the preceding time of opening by detecting the starting-up of blades forming the diaphragm of a half-open type shutter serving also as the diaphragm. CONSTITUTION:The mechanical action of a half-open type shutter 2 is started by a first pulse. When shutter blades 34 and 35 are started to move, a pulse plate 31 is rotated, a pulse phiF is generated with a hot interrupter 33, and transmitted to a system control 7. When the second pulse of phiR to show the preceding time of shutter opening is obtained, the system control 7 commands the action of the clock pulse phiAB to be added to the anti-blooming gate of a solid- state pickup element 3. Thus, the image pickup device whose anti-blooming performance is high and dark current is low, can be attained.

Title: Dc voltage compensator
Inventor: ODAGI HIROSHI
IPC: H02J9/06
Filed: 1991-11-19
Abstract: PURPOSE:To enhance output performance of SID by providing a circuit for compensating the operating speed of a silicon dropper (SID). CONSTITUTION:Maximum variation of DC input voltage to an SID 10 decreases abruptly from uniform voltage of a battery 11 to a rated voltage when the load current 6b is high. The voltage variation depends on the inherent charging voltage of the battery 11 and contactors 10a, 10b are subjected to step by step sequence control (10b-10a) for the abrupt voltage variation from a state where all silicon rectifiers 10c are connected to a state where all silicon rectifiers 10c are short-circuited through the contactor 10a. Since the SID 10 can not be controlled transiently within an allowable output voltage range for the abrupt input voltage variation, a thyristor switch 9 connected in parallel with the SID 10 is operated to compensate for the operation of the SID 10. According to the constitution, transient instantaneous variation of output voltage can be suppressed resulting in the enhancement of the output performance of the SID 10.

Abstract: PURPOSE:To enlarge a back machining range in holding a work right even at time of back machining by installing a second guide bush which intermediately guides the work in and around a machining point of a tool on a wirking spindle of a second headstock performing the back machining. CONSTITUTION:When back machining is performed on a back machining spindle 300 by a second headstick 44, a second guide bush 50 is clamped to a bed 10 by means of a second guide bush holder 52 in order to intermediately guide the work in and around a machining point. This bush 50 is installed on the back machining spindle 300, and the headstock 44 holds the work as shown in a chain line, intermediately guiding the work in and around a second machining point in a state of sliding on the back machining spindle 300. In this case, this back machining is carried out by a back machining tool 54 detachably held on a second turret 26, and an intersection point between a second infeed spindle 400 and the work forms a back machining point. Consequently, at the back machining, even if the headstock 44 supports the work with a large over- hang, it is sufficiently endurable against any machining large in side pressure so that highly accurate machining is thus actualized.
