Title: Power-factor detection circuit
Inventor: AKAMATSU KENZOU
IPC: G01R21/06
Filed: 1979-07-17
Abstract: PURPOSE: To accurately detect a power-factor, by combining the positive and negative rectified waves of a sinusoidal voltage signal with each other depending on a logical level signal generated by converting a current signal.  
     CONSTITUTION: The positive and negative portions of a sinusoidal voltage signal 1a are rectified to obtain rectified waves 1b, 2b. The wave form of a current signal 4a having a phase difference of ϕ from the voltage signal is changed at 4 to generate a logical level signal 4b. The rectified signals 1b, 2a are synthesized at 3 with each other depending on the logical level signal 4b. For example, the polarity of the rectified signal 2a is inverted for a time t 1 Wt 2  to perform the synthesis. The rectified signals 1b, 2a are smoothed and averaged at 5 to generate a signal 5a. The synthesized signal 3a is divided by the signal 5a to generate a signal 6a corresponding to  the power-factor of cosϕ. This results in accurately detecting the power-factor  through a simple construction.

Title: Load control circuit
Inventor: OGAWA TATSUO
IPC: H03K17/28
Filed: 1981-06-13
Abstract: PURPOSE:To ensure a sudden change from the turn-on mode to the turn-off mode and at the same time to eliminate the noise, by applying the positive feedback to a field effect transistor in a certain period of time after detaching a finger from a push-button switch and breaking instantaneously a Triac. CONSTITUTION:When a finger is detached from a push-button switch, a capacitor 6 starts the discharging. Then the gate voltage VGS of an FET8 gets gradually close to zero, and the drain current IDS increases gradually. According to this increment of the IDS, the VBE of a TR19 increases and the base current begins to flow. As a result, the collector current flows and the VGS gets closer to zero. Accordingly the IDS increases more to increase the VBE to give a sudden increment to the collector current. As a result, the VGS is instantaneously set zero at the time t4 to apply the positive feedback. Thus the FET8 conducts, and at the same time a thyristor 10 is broken. Accordingly a Triac 11 is broken to be turned off. The trigger voltage V4 is kept at a comparatively low level at a moment when the Triac 11 is turned off. Thus the frequency noise is reduced for the Triac 11.

IPC: F24C7/04
Filed: 1986-04-21
Abstract: PURPOSE:To save energy of the foot warmer and to improve the safety thereof by controlling to cut off power supply to the foot warmer when a heater holds a predetermined output value which is reduced from the rated output or the temperature within the foot warmer holds a predetermined value for a predetermined period of time, due to the absence of one who takes warmth. CONSTITUTION:When power is supplied to a heater 1 of the foot warmer, the temperature within the foot warmer rises, and reaches a preset value in a short period of time. At the same time, the output of the heater 1 is gradually reduced and has a low value. Furthermore, whether the temperature within the foot warmer holds a predetermined value or the output condition of the heater 1 holds a predetermined output value reduced from the rated output or the temperature or the output is under a varying unstable condition, is judged by a control unit 11 performing the secondary side voltage check of a current transformer within an external controller 9 or the temperature check. When the temperature within the foot warmer is a preset temperature and the output condition of the heater 1 is reduced with respect to the rated output and is constant and continued for a predetermined period of time, the power supply is cut off.

Title: Contact type electrostatic charging device
Inventor: CHIN TEIU
IPC: G03G15/02
Filed: 1994-04-28
Abstract: PURPOSE:To obtain a contact type electrostatic charging device whose reliability is high and which can execute uniform electrostatic charge by setting the resistivity of an electrostatic charging member in the flowing direction of an electrostatic charging current to a specified value. CONSTITUTION:The sheet-like electrostatic charging member 12 is constituted of a metallic layer 14 connected to a feeding power source 22 through an electrical conductive member 15 and a resistance layer 13 laminated on the layer 14. Besides, it is formed to be sheet-like as the whole and provided with elasticity. The surface of a photosensitive layer 16 is electrostatically charged by injecting electric charge at a place where the layer 13 and the layer 16 are brought into contact with each other and by executing the electric discharge at a place where they are not brought into contact and a very small gap is formed. In such a case, since the current flows in the thickness direction of the layer 13, the substatial resistivity in that direction is set to be within the range of 10<3>-10<8>OMEGA, preferably, 10<5>OMEGA. There is such possibility that electrostatic charge irregularities by the nonuniform electrostatic charge by the abnormal electric discharge is caused when the substantial resistivity of the layer 13 is smaller than 10<3>OMEGA and the imperfect electrostatic charge is caused when it is larger than 10<3>OMEGA.
