Title: Image forming device
Inventor: KAMEI NAOYUKI
IPC: G03G15/20
Filed: 1993-01-14
Abstract: PURPOSE:To eliminate the effect by a carton, etc., and to improve the fixability of a fixing device by providing the sensor of sheets of paper detecting the presence of sheets of paper on the side of a paper ejection in the vicinity of a fixing part and turning on a heating means for a specified time when the form is detected. CONSTITUTION:A paper ejection sensor 23 is disposed in a close vicinity to the fixing part B of the paper ejection side of the fixing device 22 and a On signal is outputted when the transfer paper S is detected. In other words, the paper ejection sensor 23 has also a function as the sensor for sheets of paper. When the ON signal is outputted from the paper ejection sensor 23, a controller 33 turns on a heater lamp 22a for a specified time. Thus, the on/off of the heating means are controlled separately from normal temperature control, so that the heating means is turned on before a time when a part where a temperature is dropped is moved to the detecting part of a temperature detecting means and heat is supplied to the fixing roller. Therefore, even if the sheets of paper of a large heat capacity such as the carbon is used, the surface temperature of the fixing roller is never drastically dropped to the temp. lower than a set temperature.

Title: Ccd solid-state image pickup element
Inventor: HIKIBA MASAYUKI
IPC: H04N5/341
Filed: 1992-01-16
Abstract: PURPOSE:To increase an output voltage by changing a conductance of a load MOSFET complementarily with respect to an amplifier MOSFET of a source follower circuit to increase the amplitude. CONSTITUTION:When a voltage signal generated from a detection capacitor CS is high, the conductance of amplifier MOSFETs Q2, Q4, Q6 is increased, a large current flows to a resistor RS thereby increasing a source potential. Thus, the conductance of load MOSFETs Q3, Q5, Q7 in a feedback amplifier AMP is decreased, the source potential of the Q2, Q4, Q6 is increased to increase the output voltage. When a voltage signal is low, the output voltage is lowered by a similar action. Then the output voltage is increased by applying positive feedback to a source output voltage of each amplifier MOSFET by the load MOSFET controlled by the self bias resistor RS and a feedbacks signal of the AMP.

Title: Time base controller for information recording disk reproducer
Inventor: OKANO TAKASHI
IPC: G11B19/247
Filed: 1989-01-12
Abstract: PURPOSE:To immediately lock in time base servo control even after a jumping action by setting the phase difference between a reference signal and a synchronizing signal at a level equal or close to the phase difference set at generation of a jump command when a prescribed time elapsed from the end of the jumping action. CONSTITUTION:When a tracking servo mechanism 4 finishes a jumping action of a reading pickup in response to a jump command pulse, a reproduced synchronizing signal is transmitted again from an extracting circuit 6. Then a D type flip-flop 24 is inverted by a head edge of first reproduction synchronization after the end of the negative pulses supplied from a monostable multivibrator 23. Thus an N-notation counter 22 restarts its integrating action. Therefore, a point P equal to the counting stop time point of the counter 22 is coincident with the head edge of the reproduction synchronization. The phase difference DELTAphi is defined between said head edge and a reference synchronizing pulse signal E. Thus it can be supposed with high possibility that the phase difference is kept as DELTAphi between the head edge of a first reference synchronizing pulse E obtained after the restart of a counting action and the head edge of the corresponding reproduction synchronizing pulse C. As a result, a spindle servo is immediately locked in.

IPC: H02P3/06
Filed: 1993-01-18
Abstract: PURPOSE:To obtain a drive controller for power windows which can effectively avoid unnecessary interposition detecting operations and can effectively prevent the erroneous occurrence of an interposition. CONSTITUTION:When the threshold SL of a motor current used for detecting the overload of a motor is changed to a higher threshold SH higher than the current value of the motor, the threshold is compared with a prefixed discriminating value AL. Therefore, unnecessary interposition detecting operations can be effectively avoided and, at the same time, when the threshold SL is higher than the discriminating value AL, the erroneous occurrence of an interposition can be effectively prevented by reversing or stopping the motor or issuing a warning to the outside with a buzzer, etc., based on the discriminated results.

Abstract: PURPOSE:To prevent misoperation by outputting results detected by respective a engagement detecting means through a specified logical relation so as to detect engagement of a clutch. CONSTITUTION:When a clutch change-over lever is shifted into the forward position, the piston valve 13 and the rod 14 of each of clutch engagement sensors 11 and 12 are moved and at this time, the engagement detecting signals (a) and (b) from both sensors 11 and 12 change to '0, 0' from '1, 1' so that a signal of '1' indicating the forward engagement of clutch is sent to a controlling unit. When a valve spring 15 has a lower spring constant, the liability of trouble may get higher, however, a '0' of the engagement detecting signal (b) from the other sensor 12 can be obtained. Engaged state of the clutch can then be detected accurately so that any misoperation of the hydraulic clutch can be prevented.
