Title: Transfer preprocessor of electronic copying machine
Inventor: NAKAI HITOSHI
IPC: G03G15/16
Filed: 1983-06-29
Abstract: PURPOSE:To improve transfer efficiency and prevent a form from being stained by providing a transfer pre-exposure lamp which exposes the internal surface of a photosensitive body from inside of the photosensitive body right in front of the transfer area of a transfer corotron which transfers a toner image formed on the surface of the photosensitive body.

Title: Dc motor drive circuit
Inventor: SAIJO HIROAKI
IPC: H02P7/29
Filed: 1986-05-20
Abstract: PURPOSE:To improve the precision as high as possible by conducting the drive control in a digital circuit. CONSTITUTION:A counter 11 divides a clock sent out by a clock generation circuit 1 and sends out a carry signal as a preset signal to a counter 12. The counter 12 is preset by this carry signal and subtracts the numeric value of a register 3 based on the clock. When the discrete value gets to naught, the counter 12 sends out the carry signal to NOT circuit 13. The NOT circuit 13 sends out '1' to a power amplification circuit 7, while the counter 12 is counting. When the counter 12 sends out the carry signal, '0' is sent out to the counter 12 and the power amplification circuit 7. The power amplification circuit 7 does not supply the driving current to a DC motor 8 while '0' is being inputted.

Title: Gas/oil pressure type actuator for valve
Inventor: FUKUNAGA AKIO
IPC: F15B11/072
Filed: 1981-07-24
Abstract: PURPOSE:To prevent an actuator from being broken due to an overload by cutting off a pipe line with a pressure cut-off valve when the gas pressure in the pipe line exceeds a certain value so that the output of the actuator will not exceed the design allowable output. CONSTITUTION:As the load of a valve 15 is increased due to some influences during the operation exceeding its rating, the output of an actuator is correspondingly increased, but when the gas pressure in a pipe line 23 reaches a preset pressure, a pressure cut-off valve 13 normally set at an open position is switched to a close position, cutting off the pipe line 23, thus the gas feed to a tank 8a is stopped. Accordingly, the output of the actuator is made a proper output corresponding to the required power of the valve irrespective of a further increased pressure in the pipe line, thereby preventing an overload of the actuator.

Title: Planar heater
Inventor: YAMAMOTO YUUJI
IPC: H05B3/00
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To sustain an optimal surface temperature by providing a plurality of heaters arranged in a heating unit, and a temperature detector therefor integrated with the heater and then controlling the temperature of the plurality of heaters sequentially thereby detecting the temperature accurately. SOLUTION: When the temperature of an electric carpet is varied through heating of a heater 1, impedance of a temperature-sensitive material 3 is varied to cause variation in the current flowing from a temperature detecting line 2 to a heater 1. The temperature variation is detected in the form of temperature signal by a temperature detecting means 7. Since impedance of the material 3 decreases as the heater temperature increases when a relay 4 is turned on, current increases and the temperature detection signal decreased. When the temperature detection signal becomes smaller than a temperature set signal, a comparison means 6 delivers a set temperature arrival signal to a temperature control means 8 and turns the relay 4 off. Consequently, current does not flow and the means 7 delivers a constant High voltage.

Abstract: PURPOSE: To reduce the number of power source batteries to the minimum by decreasing the winding-up torque and using the motor torque efficiently, by performing the reciprocal motions of iris control mechanism and shutter charge mechanism by means of notch gears.  
     CONSTITUTION: Rotations of the motor are transmitted to a notch gear 35b through speed reducing gear train, and a winding-up plate 42 is rotated by way of a two- stage gear 41.

Filed: 1993-05-19
Abstract: PURPOSE:To prevent an exhaust port from being closed, and dust from being blown even with a cleaner body kept upright by forming a multistage of exhaust ports having different diameter along the longitudinal direction of the body. CONSTITUTION:Exhaust ports 74 and 75 for blowing outside the air drawn through an electrical blower are formed to be semicircular along the external surface of a vacuum cleaner body 11. Also, the ports 74 and 75 are made to have different diameter, and arranged in a multistage while being dislocated along the longitudinal direction of the body 11. As a result, an enough distance between each of the ports 74 and 75 and the rear edge of the body 11 can be maintained. Thus, the ports 74 and 75 are not closed with the body 11 kept upright. The exhaust air, after guided along the internal curvature of an exhaust port cover 18 is dispersed toward the rear side of the body 11 along the external surface thereof. The force of the exhaust air is thereby weakened and blown out. According to this construction, a user positioned in front of or at the side of the body 11 becomes free from unpleasant feeling due to his/her exposure to the exhaust air, or the occurrence of dust blow and dispersion or the like on the surface of a cleaning object due to the exhaust air can be prevented.
