Title: Electrophotographic device
Inventor: WAKASAKI YOSHIKAZU
IPC: G03G21/00
Filed: 1986-11-19
Abstract: PURPOSE:To remove dew in a short period without adding any new heater specially by providing an input means which discriminates a dew condensation state. CONSTITUTION:When a power switch 28 is turned on, a fixation lamp 15 illuminates and this state continues for a time t0 until the fixing roller 14 reaches specific temperature. At this time, when a user turns on a switch 19 in the dew condensation state, the fixation roller 14 reaches the specific temperature and then a main motor 22 turns on. Then while a photosensitive body 8 and a developing device 7 begin to rotate, an exposure lamp 17 illuminates to make a scan continuously while irradiating an original surface. Simultaneously, paper feed rollers 4 and 5 and high voltage electrostatic chargers 9, 10, 11, and 12 are still held off. Further, a fan motor 18 also turns on to send the outside air into the machine. Consequently, the temperature in the device rises to remove dew from the glass surface 1 of an original platen, the surface of the photosensitive body 8, and respective parts in the device.

Filed: 1988-10-31
Abstract: PURPOSE:To simplify construction while maintaining proper function by providing a reversing mechanism in a casing or at one end of a shaft part, and using both of rotation reversed therewith and non-reversed rotation as output. CONSTITUTION:As the driving torque of a motor M is equally distributed for the rotation of a casing 2 and a shaft part 16, it follows that the motor M itself performs as a differential mechanism. Furthermore, rotational output from either of the casing 2 and the shaft part 16 is reversed with a reversing mechanism 93 and either output works in the same turning direction. When both types of output are respectively delivered to right and left wheels, therefore, equal driving torque works upon both wheels. According to the aforesaid construction, when driving resistance is different between both wheels, a vehicle advances straight. Also, when the driving resistance is different and one of the wheels drops in speed, the other wheel increases in speed corresponding, thereby causing the turn of the vehicle. According to the aforesaid construction, the device in the title becomes capable of pertinent power distribution necessary for the travel of the vehicle, without any separate installation of a differential mechanism, a flow divider and the like.

Abstract: PURPOSE: To detect the phase difference of an EPR signal accurately by converting a sample-and-hold output into a five-valued signal. CONSTITUTION: A PLL circuit 45 comprises a level phase detection circuit including a five-valued decision circuit 5 and a phase difference detection circuit 7, a loop filter 8, and a voltage controlled oscillator 9.

Abstract: PROBLEM TO BE SOLVED: To improve the aerodynamic performance of an impeller while lowering the air resistance of the impeller and sealing a clearance between a blade and a plate by integrally forming at least one of a front surface plate and a rear surface plate with the blade. SOLUTION: An impeller is formed of a front surface plate 52 having a suction port 51 in a top surface thereof, a rear surface plate 53 provided under the front surface plate 52 opposite to each other, and plural blades 54 arranged so as to be pinched between both the front and rear surfaces 52, 53. The front surface plate 52, the rear surface plate 53 and the blades 54 form plural air discharge ports 55. Since the front surface plate 52 is integrally formed with the blade 54, a fastening projection for fixing the front surface plate 52 to the blade 54 is not formed in the top surface of the front surface plate 52, and air resistance in the top surface of the front surface plate 52 is lowered, and since a clearance is not generated between the front surface plate 52 and the blade 54, air-tightness is increased so as to improve the aerodynamic performance.

As a result, the flushing of water in the specific gravity compensating device 8 is prevented and the lowering in pressure is also eliminated. Therefore, the water level in the body part of the heat exchanger can be detected accurately.

Filed: 1994-11-11
Abstract: PURPOSE: To provide an echo canceler from the chip of a DSP by comparing the levels of both input signals from the transmission/reception side with the line side and switching the echo canceler according to their levels. CONSTITUTION: A level comparator 7 is provided to compare the input signal on the line side with the input signal on the HF side and to output a switching signal 8 corresponding to the levels of both the signals. At the time of silence during an operation and when the level of the input signal on the HF side is higher than the level of the input signal on the line side, the switching signal 8 from the level comparator 7 shows the operation of the echo canceler on the HF side and according to this instruction, all SWS 1-7 are connected to the side of (b). Oppositely, when the line side input level is higher than the HF side input level, the switching signal 8 from the level comparator 7 shows the operation of the echo canceler on the line side, and the SWS 1-7 are connected to the side of (a).  Since only one of both the echo cancelers on the HF side and the line side is used while being switched, an arithmetic throughput on the DSP chip can be reduced by half.
