Title: Transfer device for electrophotographic copying device
Inventor: NIMATA YUKIO
IPC: G03G15/16
Filed: 1990-05-30
Abstract: PURPOSE:To prevent ozone from being evolved and to accomplish a transfer operation by which the back surface of a transfer paper is not stained by providing a contacting member which contacts and electrostatically charges the back surface of the transfer paper on the upstream side of a photosensitive drum and impressing the bias voltage of a polarity reverse to toner on the contacting member. CONSTITUTION:The contacting member 21 which contacts and electrostatically charges the back surface of the transfer paper P is provided on the upstream side of the photosensitive drum 2, and a power source device 31 which impresses the bias voltage of the polarity reverse to the toner on the member 21 is also provided. Therefore, the member 21 on which the bias voltage of the polarity reverse to the toner is impressed contacts and rubs the back surface of the transfer paper P on the upstream side of the drum 2, so that the back surface of the transfer paper P is electrostatically charged to have the polarity reverse to the toner. Thus, the ozone is not evolved because the back surface of the transfer paper is electrostatically charged by allowing the member 21 to contact with the back surface of the transfer paper when a toner image is transferred to the surface of the transfer paper from the drum 2. Since the member 21 does not contact with the drum 2, the back surface of the transfer paper is prevented from being stained by the member 21.

Title: Hot-water tank
Inventor: FUJISHIMA MICHIYUKI
IPC: F24H1/18
Filed: 1986-06-17
Abstract: PURPOSE:To prevent the generation of much amount of gas, generated in a hot-water tank when the tank is not used for a long period of time, and permit the delivery of hot-water quickly from a cock when the tank is reused, by a method wherein, a control means, which detects the existence of the electric source input of a heater and effects the opening and closing of a corrosion protection circuit, is equipped in the title tank. CONSTITUTION:When a timer switch 5 and a leak breaker 6 in a 200V electric source circuit 4 are being put ON, a second relay 20 is put ON whereby the relay contact 20a of the circuit of a D.C. electric source device 8 is closed, corrosion prevention electric current is conducted from corrosion prevention electrodes 3 when there is water in a tank, the contact 13b of a first relay 13 is closed and the conduction of a heater 2 is started. The corrosion prevention electrodes 3 serve both for corrosion prevention and water detection. On the contrary, when the timer switch 5 and the leak breaker 6 are being put OFF, the relay contact 20a is opened and the corrosion prevention electric current is not conducted. Thus, the corrosion prevention circuit is put OFF automatically when the tank is not used whereby the generation of gas due to corrosion prevention may be prevented.

Filed: 1987-06-04
Abstract: PURPOSE:To eliminate the production of a distorted wave due to nonlinearity of a radio receiver by extracting a level difference at every reception signal frequency between plural antennas so as to remove a disturbing wave at the pre-stage of the radio receiver. CONSTITUTION:After the phase of output signals of reception antennas 11, 12 is adjusted by phase adjusting devices 21, 22 respectively, the result is inputted to a signal synthesizer 30. A disturbing wave signal level (b) is adjusted to the same level as that of a disturbing wave signal level (a) by the signal synthesizer 30 to obtain a frequency spectrum signal (c), and it is synthesized with an output signal of the phase adjusting device 21. That is, the signals of the same frequency are subjected to level difference calculation and a frequency spectrum signal (d) is outputted to a receiver 4. Since the disturbing wave signals (a), (c) are the same level in this case, the difference is '0' and the disturbing wave signal does not appear in the signal (d).

IPC: B24B13/04
Filed: 1989-06-02
Abstract: PURPOSE:To prevent the occurrence of abnormal wear, the grinding burn, or the crack of a grinding stone and to perform a grinding work in a short time with high precision by a method wherein the revolving speed of a work is gradually changed so that a grinding ratio is kept at a specified value regardless of a revolving angle. CONSTITUTION:The tip of a work W rotated centering around an axis Z is pressed against a grinding stone G, and by revolving the grinding stone G relatively to the work W, the tip of the work is ground in a spherical shape. In this case, the revolving speed of the work W is gradually changed so that the revolving speed when the central part of the tip of the work is in contact with the grinding stone G is increased to a value higher than that when the outer part of the tip of the work is in contact with the grinding stone. This method always keeps a grinding ratio at a specified value regardless of a revolving angle theta, and prevents the occurrence of abnormal wear, the grinding burn, and the crack of the grinding stone G.

Title: Air-conditioner for vehicle
Inventor: DOI SHIGENORI
IPC: B60H1/00
Filed: 1986-06-18
Abstract: PURPOSE:To prevent the degradation of the warming feeling, by providing a setting means for increasing the rotary speed of a fan corresponding to the elapsing time when an operated temperature is higher than a setting level. CONSTITUTION:When the engine water temperature exceeds over a predetermined level, it is decided whether the start control is completed and if it is not completed, a comparator 47 decides whether an operated temperature is higher than a predetermined level. If it is higher than a setting level, a setting means 48 provides a predetermined starting voltage to a fan 3. Since the starting voltage lags to produce a high voltage, the time point when the fan 3 rotates with a high speed lags by a predetermined time and the engine water temperature increases during said interval. Since the rotary speed of the fan 3 can be increased as a variable of the rotary speed as the time elapses, the air flow of the fan does not increase abruptly under warming thereby the warming feeling of the crew does not degrade.
