Title: Method of controlling inverter
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/525
Filed: 1979-02-02
Abstract: PURPOSE: To shorten the inverting period of an inverter by detecting the current of a capacitor for storing an inverting energy to switch the inverting mode.  
     CONSTITUTION: Choppers 13, 14 and auxiliary thyristor are energized simultaneously when an auxiliary thyristor 11 is conducted. Then, a capacitor 17 is discharged. The current of the main thyristor becomes zero, and the load current is inverted. When a zero current detector 67 for checking the difference output of a difference current detector 66 receiving the inputs of current detectors 18, 19 detects zero current and accordingly detects completion of inversion, the choppers 13, 14 are opened and the main thyristor is conducted. The thyristor 11 is rapidly turned off to thus complete the inverting sequence. At the next inverting timing an auxiliary thyristor 12 conducted and the main thyristor is turned off. Thus, the capacitor 17 is charged, and the thyristor 12 is turned off thus to complete the inversion.

Filed: 1990-01-19
Abstract: PURPOSE:To simply and surely read only a desired code by inputting and storing optically a code through a read window, and outputting the stored code at the time of time-up. CONSTITUTION:While a read window 12 moves onto an object code, the operation start and reset of a timer means are repeated, and the code which is read newly is stored successively in a storage means instead of an old code. In such a state, in the end, when the read window 12 is separated from the object surface on the object code, the code is eliminated, and when a prescribed time elapses, the timer means becomes time-up. As a result, data output means outputs the latest code stored in the storage means, that is, the object code to the outside. In such a way, only the last read code at the time when the device is kept away from the object surface is outputted, and only a desired code is surely obtained.

Title: Recording and reproducing method of digital signal
Inventor: SUGIKI HIROSHI
IPC: G11B15/467
Filed: 1984-01-25
Abstract: PURPOSE:To attain compatibility between devices by recording a pilot signal independently of a digital signal, recording and reproducing a positioning signal having a start edge near the center and much azimuth loss and detecting the pilot signal from an adjacent track. CONSTITUTION:When a signal S22 is applied from a detection circuit 56 at the rising of a switching signal S1', an output signal S24 of an FF57 changes from a high level to a low level, a signal S24 is fed to a switch circuit 25 and the circuit 25 is changed over to a contact (b) side. As a result, a signal having a prescribed potential Vcc is led out of a terminal 58 to an output terminal 26. This signal is fed to a capstan servo system so as to attain tracking control. When the potential Vcc is positive, for example, the tape feeding is quickened via a capstan servo system, the head is moved to the next track corresponding to the own azimuth substantially so as to attain normal tracking operation and when the Vcc is zero, the feeding of the tape slows down and the head is retracted to the track during scanning at present substantially. Thus, the compatibility between devices is attained.

Title: Driver for original setting table or optical device
Inventor: YAMAGATA RIYUUTAROU
IPC: G03B27/62
Filed: 1980-01-31
Abstract: PURPOSE:To shorten the time of copying by returning an original setting table at a higher speed than an exposure speed by using an endless chain rotating in one direction and a prescribed hook member and spring. CONSTITUTION:Chain 4 rotating in one direction is fitted with two moving pieces 8 and 9 at symmetric positions. Setting table 3 is provided with spring 11, hook member 12 and stopper 15. In this constitution, as chain 4 is driven, hook member 12 is inhibited by stopper 15 from rotating, so that setting table 3 will move at an exposure speed in direction 10 together with moving piece 8. On the completion of the exposure, solenoid 16 is excited to move back stopper 15 and hook member 12 rotates counterclockwise to return setting table 3 at a high speed by spring 11. At this time, member 12 meets return member 17 and is displaced at some angle, and then the other moving piece 9 is moved to a hook position, holding the next exposure in readiness. Thus, while setting table 3 is returned at the high speed, the exposure can be done twice during the single rotation of chain 4, shortening the time of copying.

IPC: H03K3/02
Filed: 1981-01-29
Abstract: PURPOSE:To obtain the energy characteristics with broader voltage range, by inserting a capacitor between a coupling point of two voltage division circuits and one end of a power supply. CONSTITUTION:A charging capacitor 54 is inserted between a coupling point 52 where voltage division circuits 42, 43 are coupled from a voltage dividing point 48 via diodes 50, 51 and one end of a power supply 41. The potential of the point 48 is etaVd, where the voltage dividing ratio is eta, and the potential of power supply is Vd. At a voltage dividing point 49, the potential is Vd-Vz,  where Vz is a voltage of a Zener diode 46. It is possible to set Vz and eta so that the voltage is at first Vd-Vz>etaVd, and becomes Vd-Vz=etaVd through  gradual decrease and also, Vd-Vz<etaVd at further decrease. Until the power  supply has a certain voltage, the voltage traces between JK, straight line portion of a characteristic curve 72 of the circuit 43, and when the voltage further  decreases, it traces between LM, straight line portion of a characteristic curve  71 of the circuit 42. Thus, the range of equienergy characteristics can be extended remarkably.

IPC: H04N1/41
Filed: 1981-01-31
Abstract: PURPOSE:To increase the coding efficiency, by applying a binary coding system using the correlation of the inter-block gradation for the gradation information to the picture element information. CONSTITUTION:A halftone facsimile signal 5 is divided into the blocks comprising several picture elements and then separated 1 into the gradation information representing the gradation of the blocks and the picture element information showing the image resolution to perform the coding 2 and 3. In this case, a picture element having the same gradation as the mean gradation of the block is categorized to the lighter gradation information, and the mean gradation of the block is used as the only gradation information in case the gradation is substantially even within the block. Then the picture element information equivalent to the picture element showing the mean gradation is formed to all picture elements. After this, the picture element information is binary code 2, and at the same time the gradation information is coded 3 with a flag showing that the gradation of the block to be coded is equal to the gradation of the same kind that emerges immediately before. Otherwise the coding 3 is carried out with use of the flag and the gradation information.

Filed: 1983-01-28
Abstract: PURPOSE:To shorten a measuring interval by rapidly performing the restoration of the oxygen amount in a capsule, by reversely diffusing external oxygen into the capsule by forcibly supplying a current to a solid electrolyte substance. CONSTITUTION:Current supply to an oxygen sensor 31 due to a diffusion limit current measuring system is initiated from a constant-current unit 32 by the signal from a control unit 34 to start measuring time T1 and, when the oxygen concn. in the capsule of the sensor reaches zero, specific voltage change is detected by a voltage detecting unit 33 and a completion order signal is applied to the control unit 34 to complete the measuring time T1. In the next step, an oxygen concn. proportional to T1 is displayed by a display unit 35 and a current having polarity reverse to that of the above mentioned current is supplied by the order signal from the control unit 34 to start a stand-by time T2. When the concn. difference between the inside and outside of the capsule of the sensor is almost eliminated and the potential difference between electrodes reaches zero, the stop signal from the voltage detecting unit 33 is applied to the control unit 34 and the current supply is stopped to complete T2.
