Title: Voltage control of voltage signal
Inventor: JIYATSUKU RAYUFUEERU
IPC: H05G1/20
Filed: 1989-04-10
Abstract: PURPOSE: To make the peak value of a high-voltage signal constant to a given value, by controlling the action of an inverter for generating a ripple low-voltage signal, in accordance with the voltage change of the high-voltage signal obtained by making the ripple low-voltage signal as a basis. CONSTITUTION: A low-voltage A.C. is rippled by an ressonant inverter 2 to be voltage-increased by a step-up transformer 4, and then is rectifiably filtered in a rectification/filter circuit 5. Generated high voltage is detected as a signal KV via a partial voltage bridge 14. The signal KV is compared with a value, wherein a change δKV1 of high voltage, rectified during one ripple pulse, is subtracted from reference voltage Vref via comparators 15 and 16 and a storage circuit 17. When the signal KV is smaller, the inverter 2 is controlled so that the next pulse can be immediately generated via a pilot circuit 3. In this way, a high-voltage dc signal having a constant peak value of high voltage can be obtained.

Title: Hysteresis circuit
Inventor: UMEKI YOSHITAKA
IPC: H03K19/088
Filed: 1982-05-28
Abstract: PURPOSE:To set a high and a low threshold value of an input independently and to avoid the dependancy of the fluctuation of a power supply voltage, by inserting a PNP transistor (TR) and a diode to a phase split stage of a TTL gate circuit. CONSTITUTION:The PNP TRQ18 and the diode D11 are connected to a base and a collector of a TRQ13 of a phase split stage as shown in Figure. When a low level voltage is applied to an input terminal 11, a TRQ11 is conductive, TRs Q12-Q14, Q18 are cut off, a TRQ16 is conductive and an output 14 shows a high level. In increasing an input voltage V1 and exceeding a high threshold value VTH, the Q12-Q14 are conductive one after another and the output 14 changes to a low level. Since a collector-emitter voltage is decreased when the Q18 is conductive at the same time, the Q12 is cut off. Even if the voltage V1 is decreased gradually and reaches the voltage VTH, the output 14 keeps a low level, but when the voltage V1 reaches the low threshold voltage VTL, a collector current of the Q18 flows via the D11, the Q13, Q14 are cut off, the output 14 changes to high level with the Q16, Q17 and the Q18 is cut off.

Filed: 1987-04-15
Abstract: PURPOSE:To generate a horizontal synchronizing signal at a prescribed timing at all times by dividing an optical output of a laser beam held by a peak hold means into a prescribed potential and comparing the optical output of a detection element with the potential so as to generate the horizontal synchronizing signal. CONSTITUTION:When a peak hold means 2 holds the peak value of the optical output of a laser beam detected by a detection element, potential division means R1, R2 divide the held peak value into a split potential of a prescribed potential. A signal generating means 4 compares the optical output of the detection element with the split potential to generate a horizontal synchronizing signal giving a picture write timing in the main scanning direction. Thus, even when the optical output of the laser beam to be oscillated is fluctuated, the horizontal synchronizing signal deciding the picture write timing in a constant timing at all times is outputted with high accuracy.

IPC: G11C11/14
Filed: 1981-06-15
Abstract: PURPOSE:To simplify the control from the host system side, by detecting that a cassette type bubble memory is connected to a controlling circuit and a driving circuit through the change in the voltage level caused by a mechanical switch, etc. CONSTITUTION:When a 5V voltage is applied across a signal line 11 and the signal line 11 is grounded through a cassette 5, the signal line 11 has the same electric potential as GND whenthe cassette 5 is connected, and 5V when the cassette 5 is cut off. Therefore, a CPU10 can know whether the cassette 5 exists or not by detecting the voltage level of the signal line 11 through a path buffer 9. Consequently, when defective loop data are read out at the time point where the cassette 5 is connected, processings of data writing on or data reading from the bubble memory device can be performed by the defective loop data of the cassette which is always connected even when the cassette is exchanged.

Abstract: PURPOSE:To provide a sheet feeder with good maneuverability and economy by actuating a sheet pressing means a certain specific while after sheets were placed on a sheet placing part anew, and by stopping the pressing means after another specific period of time was delayed from when the placing part has god rid of sheets. CONSTITUTION:When a letter P is placed on a placing part 25 to shut off the beam to a letter sensor 46, a change in the detection signal A causes the CPU 47 to set a delay time of several seconds on a timer 48, whereafter the CPU will emit signals D for starting a transport belt 26, a pressure device 30 and a takeout device 40. When the placing part 25 has god rid of letters P, the sensor 46 will sense a beam, and a detection signal A be fed into the CPU 47. The CPU 47 sets a delay time of several tens of seconds on the timer 48 and then emits a signal D for stopping the transport belt 26, pressure device 30 and takeout device 40. Now the supply part stops operating. According to this arrangement, the supply part operates only when the placing part 25 is loaded with a letter P or letters, which should eliminate a considerable part of mechanical actions otherwise required.
