Title: Pulse width modulator circuit and stabilized power source using the same circuit
Inventor: ISHIKAWA TADASHI
IPC: H02M3/00
Filed: 1988-05-27
Abstract: PURPOSE:To reduce the area of a chip by storing the output of a comparator for comparing an input signal with a reference signal, and updating the stored content at a predetermined time interval. CONSTITUTION:A comparator 1 compares an input signal from a MPX circuit 3 with a reference signal from a D/A converter 5, and a latch 4 stores the output of the comparator 1. A timing generator 2 updates the stored content of the latch 4 at a predetermined time interval, the content becomes an output signal to form a pulse width modulator. A main transistor(Tr) A-13 is driven by the output A-1 of a MAIN-PWM circuit 9 to drive the primary side of a transformer A-10, thereby obtaining an output A-11 from its secondary winding. This output A-11 is divided, fed back and input to the circuit 3. An output A-12 is also obtained from the other secondary winding, a Tr A-5 is connected to a low voltage terminal, and driven by the output A-2 of a SUB-PWM circuit.

Filed: 1989-05-24
Abstract: PURPOSE:To make the title filter high performance by water-sealing the partition plates for comparing the end part of the ceramic filter, a filter chamber and a treated liquid chamber with a specified sealing member. CONSTITUTION:Insoluble solid material is removed from the high-temp. feedwater discharged from a heater 22 by a ceramic filter 50 and thereafter this feedwater is supplied to a furnace 25. A ceramic filter 57 removes the insoluble solid material having particle diameter not smaller than the specified particle diameter. Further the concentrate is returned to a feedwater introducing port 51 from the outlet 53 of concentrate by a circulation pump 62 and recycled. Cake is prevented from being formed by sticking of the insoluble solid material to the fine holes of the inner surface of the ceramic filter 57. Furthermore water is supplied from a supply line 60 of pure water for backwash and allowed to back flow through the inside of the ceramic filter 57. Thereby the solid material stuck to the fine holes of the inner surface is peeled.

Filed: 1979-10-08
Abstract: PURPOSE: To prevent customers from feeling uncomfortable even if a power failure occurs, by printing out data on a receipt in the same print format as the normal condition by an electronic cash register with a power-failure detecting function.  
     CONSTITUTION: Print flag memory 25f indicates whether one-line print data sent out of print buffer registers 25d 1 ...25d 7  to printer 34 are printed out on a receipt. After power-failure detecting circuit 36 detects a power failure temporarily and then the power failure is recovered, memory 25f is checked. Here, if it is judged that the print data are not printed out, the same print data are transferred from registers 25d 1 ...25d 7  to printer 34 again and printed out on the receipt again. Thus, the data can be printed out in the same format as that when the power failure occurs, and the data are printed out.

Abstract: PURPOSE: To improve workability and efficiency in untwisting work by arranging a rotary mechanism to freely rotate a sandwiching part to sandwich twist pair wires, a handle part to support the sandwiching part and a sandwiching part to the handle part. CONSTITUTION: When twist pair wires 16 are untwisted, first of all, the wires 16 to be untwisted are inserted into a slit 21 formed in a sandwiching part 11 of an untwisting jig 10 from a slit 21 side part. Next, a handle part 12 is operated, and a jig 10 is moved so as to be pulled out in the tip direction of the wires 16. Therefore, the wires 16 in a twisted condition get loose according to the movement of the part 11, and the wires 16 are untwisted. In this case, bearings 13 and 14 are arranged in the jig 10, and a rotary mechanism is constituted to freely rotate the part 11 to a part 12. As a result, when the part 11 is installed on the wires 16, work to perpendicularly position the part 11 to the wires 16 becomes unnecessary, and workability can be improved. The occurrence of damage in the wires 16 is also prevented, and force necessary for the work can be minimized.
