IPC: H02M5/45
Filed: 1982-05-10
Abstract: PURPOSE:To prevent the erroneous operation of control by eliminating to energize a main power source in the state that a control power source of a controller which controls an inverter is not established. CONSTITUTION:When a breaker contact MCB2 is closed, a sub smoothing condenser 12S is precharged by the DC output of a rectifier 18S through a current limiting resistor R.

Title: Back irradiation type solar cell
Inventor: MATSUMOTO HITOSHI
IPC: H01L31/04
Filed: 1978-06-29
Abstract: PURPOSE:To provide a back irradiation type element with a high conversion efficiency and a stable life by forming a Ni or carbon electrode entirely on a low resistance CdS film and a CuS layer provided on the insulated transparent substrate. CONSTITUTION:A CdS paste is screen-printed on a glass substrate 1 and then, sintered in the atomosphere of N2 or Ni-Cd to form a CdS sintered film 2 with a thickness of 30 mum and a surface resistance of 5 to 20 OMEGA/mm<2>. A Ni electrode 3 is mounted on a part of the film by plating. Then, with the Ni electrode section masked, the CdS sintered film is immersed into a CuSO4 so that P-type CuS layer 4 is electrolyzed and separated on the surface of the sintered film. Then, the Ni and carbon electrode 5 are formed on the entire CuS layer by coating. Accordingly, it is possible to apply an electrode entirely on the CuS layer by back irradiation. In addition, since the insulated substrate causes no short-circuit with the CuS layer, an excellent solar cell can be obtained with a stable life characteristics and a conversion efficiency of 10 to 11.5%.

Title: Direct current power supply device for welding
Inventor: MIZUNO MASANORI
IPC: B23K9/06
Filed: 1980-06-10
Abstract: PURPOSE: To prevent a wire from either plunging into or abnormally melting up by inputting the armature electromotive force by the inertia rotation of a DC motor of a wire feeder to an output voltage regulator upon ending of welding.  
     CONSTITUTION: If the driving of wire feeding is stopped and normally open contacts 7 are opened upon ending of welding, a wire 14 stops perfectly after it is slightly fed by inertia. Since the contacts 7 are held open, a Zener diode 23 is disconnected from both terminals of an output voltage regulator 5, and the armature electromotive force of a DC motor 10 is applied via a liminting resistance 21 and a diode 22. Hence, while the motor 10 is being run by inertia, the set value of the regulator 5 changes and the DC output changes as well in accordance with the armature electromotive force, and the DC output automatically changes in accordance with the rate of inertia feed of the wire 14, whereby the wire 14 is prevented from plunging into objects 18 to be welded or from abnormally melting up.

Title: Thyristor converter
Inventor: OOO NORIO
IPC: H02M7/12
Filed: 1984-04-20
Abstract: PURPOSE:To reduce energy loss by disconnecting a dummy resistor for obtaining a latching current of a thyristor when a load side current becomes the specified value or higher. CONSTITUTION:A current of a load side is detected by a detector 8, and the voltage of a thyristor converter 5 is controlled through an automatic current regulator 10 and an automatic pulse phase shifter 11 so that a deviation between the detected current and a current command value 9 becomes zero. In this case, a thyristor latching current obtaining dummy resistor 6 is connected with the load side of the converter 5. Thus, when the gate current of the thyristor is ON, a current is flowed to the resistor 6 to fire the converter 5, and the load current is controlled to become the value 9. Further, when the load current becomes the specified current set 14 higher than the latching current of the thyristor, a comparator 13 drives a relay 12 and releases the resistor 6 from the converter 5.

Abstract: PURPOSE:To attain high speed processing, by transferring the unit of picture information where the write is finished independently of the storage of reception information to a recognizing means, reading out the picture information from the storage means as a result of recognition or in response to the instruction of the operator independently of the transfer, and transferring the information to an output means. CONSTITUTION:When one unit of picture information is stored in a receiving buffer section 22, a communication control section 12 informs the storage to a system control section 46 asynchronizing with the operation of a recognition section 38 and an output section 44. The control section 46 instructs the start of operation to an stretching section 24A and the recognizing section 38, feeds the picture information of the buffer section 22 to a reception buffer control section 18, which transfers the information to the expanding section 24A. The expanding section 24A decodes the information and transmits the result to the recognizing section 38. During this operation, the next information is written in the reception buffer 22. The recognizing section 38 recognizes the transferred picture information and stores it in an FD 54. That is, the readout and the recognizing processing are processed in parallel. When the processing of the recognition is finished, the processing goes to the next readout and the recognizing processing. When the result of recognition requests a copy, and there exists an instruction from the operator, the control section 46 instructs the forming to the hard copy output section 44.

Abstract: PURPOSE:To enable an ignition timing compensation time corresponding to the rotational acceleration to be corrected with close tolerances, by continuously varying it in proportion to acceleration with the way setting an acceleration dead boundary to zero and then regarding this zero as a reference point outside. CONSTITUTION:To reduce ignition timing errors caused by an interval mistake in case of setting magnetic bodies 3, 4 by means of a No.1 operation circuit 9, time intervals T1 and T2 are detected from the pulse of a pickup 5 and a time Talpha corresponding to the rotational acceleration is calculated as shown in illustration by means of a crank angle phi in which intervals T1 and T2 as well as  said rotatinal acceleraion are considered existing within the dead zone. Therefore, the compensation time Talpha at the bondary of the dead zone is set to zero  and that, at the outside of the dead zone, this zero is assumed as a reference  point and the compensation time Talpha is varied continuously in conformity with  the speed of rotation so that this ignition timing system can check variations in the ignition timing angle in the case where engine speed is unstable as in engine  idling, yet even in a state of gentle increasing/decreasing speed, the dead zone  can be set as small as possible, thus permitting an accurate ignition timing compensation.
