Title: Apparatus for maintaining power supply at the time of momentary power interruption of commercial power
Inventor: RICHIYAADO EI MAACHIN
IPC: H02J9/06
Filed: 1991-05-08
Abstract: PURPOSE: To sustain power supply for computer upon instantaneous interruption of power supply by sustaining a capacitor bank in charged state during stable operation of a commercial power supply and discharging energy stored in the capacitor bank upon instantaneous interruption of power supply. CONSTITUTION: Voltage from a commercial power supply 10 is applied to a full-wave voltage doubler rectifier which generates a first DC voltage V1 being applied to a power converter 30. The first DC voltage V1 is applied across a circuit 100 comprising two capacitor banks 110, 120 connected in series. Upon interruption of the commercial power supply 10 due to some cause, the capacitor banks 110, 120 are discharged in order to sustain operation of a power converter for computer power supply.

IPC: H02M7/515
Filed: 1985-06-19
Abstract: PURPOSE:To improve the protecting function of an inverter by using an input DC smoothing condenser for absorbing an excess energy. CONSTITUTION:The output of a power converter 1 is supplied through a power converter 2' such as an inverter to a load 3. Capacitors 226, 228 are connected through fuses 221, 225, 223, 227 between the output buses P and N of the converter 1. The series circuit of the fuse 225 and the capacitor 226 is connected in parallel with power elements 21, 22 connected in series, and the series circuit of the fuse 227 and the capacitor 228 is connected in parallel with power elements 25, 26 connected in series. For example, even if the element 25, 26 connected in series. For example, even if the element 21 is shortcircuited so that the fuse 221 is melted, the excess voltage and the abnormal energy are bypassed through the diode 23, the fuse 225 and the capacitor 226, thereby suppressing the overvoltage to the element 22.

Title: Focus detector
Inventor: MATSUDA MUTSUHIDE
IPC: G02B7/30
Filed: 1977-11-02
Abstract: PURPOSE: To automatically focuse assuredly and satisfactorily by controlling the focusing and shutter operation based on the signal of an object distance due to the reference line range finder and on the signal of set distance due to the shift of photographic lens.  
     CONSTITUTION: In depressing shutter button 41 till it is locked by lever 6, switch 208 is closed to produce pulse signal which corresponds to the distance of the object due to the reference line range finder and memoryze it. When the range finding is completed, the shutter locking by the lever 6 via lever 13 by the control signal, the locking of lens barrel via lever 16 by motor 18 and via ratchet 27 are released. Next, another locking of rotation of the lens barrel is released by the depression of the button 41 via lever 15 to rotate the barrel via spring 30 and move the photographic lens 28. Accordingly, when the pulse of set distance is produced from the serrated print conductor 29 of the barrel and it coincides with the pulse of range finding, the energization of the motor 18 is interrupted, hence the photographing free from failure is done by the shutter which interlocks with the lens 28 focused assuredly and satisfactorily.

Title: Electronic balance
Inventor: FUJINAGA YASUHIRO
IPC: G01G23/37
Filed: 1979-10-12
Abstract: PURPOSE: To find the maximum value accurately and rapidly by a constitution wherein data DN is determined as a peak value when the difference obtained by subtracting the data DN obtained N pieces before the newest data D 0  from the data D 0  is negative and the difference obtained after subtracting the DN from the intermediate value thereof is also negative, based on the digital values of the output of the electronic balance sampled at every prescribed time.  
     CONSTITUTION: First, the tare value is weighed by the electronic balance 1 and stored in a tare- value register through an AD converter. The load is increased gradually as in the case, for instance, of the measurement of the breaking load, the output of the balance corresponding thereto is inputted in the AD converter 2, and a digital weighed value is outputted at every prescribed time. This output, from which abnormal data caused by any disturbance is removed by a microcomparator 3, is stored in a storage register 6 through a controlling part 7. When the difference obtained after subtracting the data of D n  (D 5 ) from the newest data D o  is positive, the following data is inputted, and when the difference is negative, the fact that the intermediate data thereof is smaller than the D n  is confirmed by the controlling part 7 and the peak value D n  is indicated in an indicating device 9 through the intermediary of a latch circuit 13. Accordingly, the peak value can be found accurately and rapidly.

Title: Cylindrical piezoelectric actuator and manufacture thereof
Inventor: ASANO YAICHI
IPC: H01L41/22
Filed: 1986-06-07
Abstract: PURPOSE:To improve reliability by enabling the displacement over the total plane and preventing a non-uniform stress inside the device by forming an internal electrode layer as a totalplane electrode having the same area as that of a piezoelectric plate. CONSTITUTION:A piezoelectric member composed of laminated plural internal electrodes 12 and piezoelectric plates 11 whose flat planes are almost circle comprises cutout planes on its both side parts. Every two exposed internal electrodes 12 are electrically insulated by depositing glass and an external electrode 13 is deposited while including those glass parts 14, thereby connecting the external electrode 13 to the internal electrodes 12 in parallel. Accordingly, there is no piezoelectrically inactive part produced by the existence of an electrode part formed by cutting partly so as to leave a crescent no-electrode part as seen conventionally in this kind of actuator. Not only it does not contribute to displacement in axial or radial direction, but also a defect of producing a non-uniform stress inside can be eliminated.

Title: Cooling fan device in internal combustion engine
Inventor: SANADA MASAKATSU
IPC: F16D47/00
Filed: 1977-11-08
Abstract: PURPOSE: To miniaturize an operational magnet of an electromagnetic clutch in the contrivance of transmitting the rotation of a crankshaft to a cooling fan with use of the electromagnetic clutch.  
     CONSTITUTION: An over-running clutch 7 is installed between the driven side of a clutch 5 and a cooling fan. When the over-running clutch 7 has the load to a fan 8 set at a settled value, its drive side 7a gets separated from the driven side, otherwise it does not power transmission over a certain settled value. In consequence, fan loss torque over the settled value does not transmit to the side of the electromagnetic clutch 5 resulting in giving no sliding on the frictional surfaces of this clutch even using the one with smaller capacity as an operational magnet of the electromagnetic clutch.

Filed: 1980-09-24
Abstract: PURPOSE:To manufacture a semiconductor device of shortcircuit electrode structure by interposing double electrodes between regions to form two same conductive type regions, thereby reducing the step of selectively diffusing or masking it. CONSTITUTION:An insulating film 12 is formed on the surface of an N type semiconductor region 11 and openings 13, 14 are formed at both sides of an isolation insulating film 12a. Then, P type regions 15, 16 are formed to form double region 20 through the openings 13, 14. Subsequently, N type regions 17, 18 are formed in the regions 15, 16 through the openings 13, 14. In this step, the region 20 is slightly expanded. Thereafter, the film 12a is removed, and a shortcircuit electrode 19 is formed to reach from the surface of the region 17 through the surface of the region 20 to the surface of the region 18. Thus, the regions 17, 18 are maintained in isolated state, and since the region 20 is interposed between the regions 17 and 18, the shortcircuit of the regions 15, 16 and the regions 17, 18 via the electrode 19 can be readily performed. Accordingly, the steps canbe simplified and the yield can be improved.
