Title: Detection circuit for ac input voltage
Inventor: TANAKA JUNZO
IPC: G01R19/165
Filed: 1993-09-24
Abstract: PURPOSE:To make it possible to increase speed of the detection by inputting an output voltage of a first comparator circuit and a reference voltage to a second comparator circuit and by feeding back an output voltage of this circuit through an attenuator circuit. CONSTITUTION:Voltage V2 of a pulsating wave obtained by rectifying AC input voltage V1 is divided and voltage V5 proportional to the voltage V2 is inputted to a first comparator circuit 9. The circuit 9 compares the voltage V5 with reference voltage V4 and it is turned on when the voltage exceeds an ON operation level and turned off when it is an OFF level or below, and outputs voltage V6 of a pulse wave. This voltage V6 is inputted to a second comparator circuit 12 and compared with the voltage V4 and the circuit 12 is turned on when the voltage exceeds the ON operation level and turned off when it lowers to the level or below, and outputs a pulse wave voltage. This voltage is fed back to an input terminal through an attenuating circuit 13, so that terminal voltage V7 is made a voltage having pulse waves and a waveform filling between them and attenuated by a time constant determined by the circuit 13. By determining the time constant so that it may not lower the voltage V7 below the OFF operation level of the circuit 12, the circuit 12 can output a detection signal P of a prescribed voltage without delay.

Title: Refrigerator
Inventor: ABIKO SEIICHI
IPC: F25D21/06
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent dewing on the outer surface of a refrigerator body at the time of stopping a compressor and to prevent rise of a suction pressure of the compressor by controlling a cold storage chamber damper according to an operating state of the refrigerator. SOLUTION: When a temperature in a deep freezing chamber rises and a cooling operation set temperature or higher of the chamber is sensed by a deep freezing chamber temperature sensor, a cooling operation is started (S12. A cold storage chamber is set to a cold storage chamber damper (R damper) closing set temperature +X deg.C obtained by setting the cold storage chamber damper closing set temperature by X deg.C higher. In this case, the R damer is controlled to be cooled. If it becomes the R damper closing set temperature + X deg.C or lower, the R damper is closed (S2, S3, S4). When the R damper is closed, cold air is supplied only to the freezing chamber, and the temperature in the freezing chamber is lowered.  When the temperature in the freezing chamber is lowered to the freezing chamber cooling stop set temperature or lower, the R damper is opened, the cold air is supplied into the storage chamber (S5, S6). When the storage chamber is cooled and a cold storage chamber temperature sensor arrives at an R damper closing set temperature (S7), a deep freezing cycle is stopped (S8).

Title: Cmos integrated circuit
Inventor: KONO TOMOKAZU
IPC: H03K17/687
Filed: 1985-10-24
Abstract: PURPOSE:To reduce a through-current, and to realize low power consumption by constituting the titled circuit so that a resistance is inserted between a complementary P-type MOS transistor and an N-type MOS transistor. CONSTITUTION:A resistance 107 is connected between a drain of a complementary P-type MOS transistor 101 and a drain of an N-type MOS transistor 104. Also, one terminal of this resistance 107 is connected to a gate of a P-type MOS transistor 102 of the next stage, and the other terminal of the resistance 107 is connected to a gate of an N-type MOS transistor 105 of the next stage. Moreover, the gate of the driven transistor 102 is set higher than the gate of the transistor 105, by a voltage drop portion which is generated when a current flows through the resistance 107. In this way, at the time of a state transition, the time when the transistor 102 and the transistor 105 are in a conducting state simultaneously is shortened, and also the sum of the gate potential of the transistor 102 and the gate potential of the transistor 105 is made smaller than the power supply voltage, by a voltage generated across the resistance 107. In this way, a peak value of a current flowing at the time of a state transition, and the power consumption is curtailed.

Title: Method for compensating welding current for transformer rectifying type stud welding machine
Inventor: KONDO YOSHITERU
IPC: B23K11/24
Filed: 1988-09-22
Abstract: PURPOSE:To keep a welding current of a secondary side constant by setting a waveform of a welding current by a prescribed rate, increasing an activity ratio of a welding voltage waveform in accordance with a descending level and allowing a welding current level to ascend, when a primary voltage of a transformer descends. CONSTITUTION:A reference sine wave of a prescribed voltage synchronizing with an input voltage is generated by a reference sine wave generating circuit 22 and inputted to a differential amplifier 24. The differential amplifier 24 compares a reference sine wave signal and a primary side input voltage signal from a primary voltage detecting circuit 20, and generates an output voltage of a level corresponding to its difference. This output voltage passes through a thyristor controller 26 and inputted to gates of thyristors 16, 18 and determines a timing of turn-on of each thyristor. When a primary voltage is in a regular state, the conduction time of each thyristor is set to a prescribed rate being under 100%. When the primary voltage drops, an activity ratio of a waveform is increased by adjusting the thyristor by an ignition signal from the differential amplifier. In such a way, a welding current of a secondary side can be maintained constant.
