Abstract: PURPOSE:To provide sequential bias to transistors(TRs) by providing conditional isolation without use of an isolation means such as a light emitting diode and a light receiving diode in pairs or a transformer. CONSTITUTION:A cathode of a diode 5 is connected to sources of both N- channel MOS TRs 2 of the 2-way switch in which gates and the sources of both the TRs2 each having a built-in diode, a positive terminal of a DC power supply 1 is connected to anodes, a switch 3 is connected to a negative terminal and when the switch 3 is closed, a DC power supply 1 forms a closed circuit applying off-control to both the TRs2 and a closed circuit to charge a capacitor 6 and when the switch 3 is opened, the capacitor 6 forms a closed circuit for forward-biasing both the TRs2 as features. Thus, switch terminals st100, st200 and the DC power supply 1 are conditionally isolated and the capacitor 6 forward-biases both the TRs2 continuously.

Title: Redundancy circuit for semiconductor memory
Inventor: FUJIWARA HIROYUKI
IPC: G11C29/00
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent the repairing efficiency from lowering by receiving a signal to be selected by a mat select circuit and an address matching signal from a redundancy circuit and producing a redundancy signal corresponding to each split block of memory array. SOLUTION: In a mat select circuit 20, one short circuit element in a set of short circuit elements is cut depending on the address of area to be repaired to select only one column arbitrarily and a signal to be selected is outputted to an array block select circuit 30. In the redundancy circuit 10a, any one short circuit element among a set of short circuit elements is out in response to address designation thus producing an address signal. An actual address signal is then acquired based on the signal thus produced in order to determine the address of an area to be repaired and an address matching signal is delivered to the circuit 30. Upon receiving a signal to be selected from the circuit 20 and an address matching signal from the circuit 10a, the circuit 30 produces a redundancy signal corresponding to each split block of memory array.

Title: Method for driving brushless dc motor
Inventor: NORIKANE YOSHIYASU
IPC: H02P6/08
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To optimumly control a brushless DC motor with the maximum efficiency at earlier timing than the usual timing by commutating the current of the motor after a prescribed waiting time on the basis of a commutating timing signal which is generated based on the voltage induced across the winding of the motor. SOLUTION: When a brushless DC motor is driven, the current of the motor is timing-control commutated by commutating the current after a prescribed period of time T on the basis of a commutating timing signal which is generated before the current is commutated as a trigger. Such a commutation that the input phase which is the winding in which the current flows from an input terminal is not switched is made normally by using the commutating timing signal as a trigger. Before the prescribed period of time T ends after the output of a comparator changes to an 'L' level from an 'H' level and a control section starts to count the time, the voltage induced across the W-phase winding of the motor become lower than the voltage at a neutral point due to the fluctuation, etc., of the rotating speed of the motor.  When the induced voltage becomes lower, the control section commutates the current to the V/W phase from the U/W phase with the commutating timing signal by stopping the counting and PWM-controlling a switching element.

Title: Fault information collection system
Inventor: KOBARI KUNIHIKO
IPC: H04M3/10
Filed: 1989-09-14
Abstract: PURPOSE:To prevent high load just after restoration of a fault by executing the transmission of fault information to a management center after an electronic exchange is made stable in the occurrence of a fault of the electronic exchange. CONSTITUTION:When a fault takes place in an electronic exchange, fault information is stored in a storage device (MM1)6 and when the fault restoration processing is finished, after a prescribed timing is taken, the stable state is discriminated and when the state is stable, the stored fault information is sent to a management center. In the discrimination of the stable state, a current CC operating rate and a stable state CC operating rate threshold level set to a storage device (MM2)7 in advance are discriminated and when the current CC operating rate is smaller than the threshold level, it is discriminated to be in the stable state. Thus, the application of the load of sending fault information amidst the centralized load after fault restoration processing is prevented.

By this method, the one end of the raw tube is fixed by the die 11 and the plug 13, while the other end is fixed by the drawing chuck 12, and the tube is formed while tension is added in the axial direction. Therefore, the drawn tube 2 is formed without deformation during processed. After the tube 2 is cut to specified length, deflection of the tube is decreased. To obtain a lightweight photosensitive drum, the thickness t is preferably controlled to 0.6 to 1.0 mm.
