Title: Grounding structure of roller for supporting transfer belt
Inventor: FUJITA YOSHIO
IPC: G03G15/16
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To enable effecting exact grounding, while preventing the rotary lock of a roller, in a grounding structure of a roller for supporting a transfer belt. SOLUTION: As for this structure, an end part of a supporting shaft 15a of the roller 15 is covered by a bearing 30, which is incapable of turning, and composed of conductive resin in a cylindrical shape with a bottom. The roller 15 is grounded through the bearing 30, by making a pawl part 31 of a grounding plate 31, bitten into an end surface 30b of the bearing 30. Since the bearing 30 is composed in a shape of a bag, toner is prevented from entering into the bearing 30, thus the bearing lock is restrained. Since the relative rotation between the bearing 30 and the grounding plate 31 is prevented, the toner is restrained from entering in-between both of when, therefore the grounding can be surely attained.

Title: Turned-off clock detecting circuit
Inventor: TOKUHARA TOSHIKO
IPC: G06F11/30
Filed: 1990-01-09
Abstract: PURPOSE:To omit the external attachment of an analog circuit consisting of a capacitor and a resistor by transmitting a turned-off clock detection signal via a clock pulse counter circuit if no external clock pulse is received while the clock pulse counter circuit counts the fixed number of clock pulses. CONSTITUTION:A device 1 consists of a clock pulse counter circuit 2 and a counter circuit restoring means 3. When an external clock pulse is turned off, a restoring signal is not transmitted from the means 3. Thus the circuit 2 counts the internal clock pulses in its initial state and transmits a turned-off clock detection signal when the count value of clock pulses reaches a prescribed level. Thus it is possible to detect the turned-off of the clock just with a digital processing operation like the counting of the internal clock pulses, etc., without using a time constant circuit for analog elements which consists of a capacitor and a resistance.

Title: Selection system of multiplex system
Inventor: SATOU TERUTSUGU
IPC: H04B3/04
Filed: 1978-01-12
Abstract: PURPOSE:To increase the reliability of circuit, by performing the selection of system through the durability of outpout pulse for the monostable multivibrator having retrigger functions. CONSTITUTION:The signal of the maximum pulse width t is fed to the a main system A and the subsystem B, and normally, signal is fed to the output C from the main system A via the selector 5. The main system A and the subsystem B are connected respectively with the monostable multivibrators 1,2 having the retrigger function. Since the output pulse width of the monostable multivibrators 1,2 is set greater than the maximum pulse width t of signal, the output pulse permanently continues until the signal is present. If the main system A is in failure, the output pulse from the monostable multivibrator 1 is stopped, resulting that the selector 5 selects it to the subsystem B and a signal is fed to the output C from the subsystem B.

IPC: H05B44/00
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a drive circuit which does not emit sound when driving loads such as an electroluminescence(EL) panel with AC and which is of small size. SOLUTION: A chopper type boosting circuit A stores high electric potential in a ceramic capacitor C of low distortion factor using zirconium titanate as a dielectric.

Filed: 1984-01-12
Abstract: PURPOSE:To obtain a molded product of uniform thickness by inserting in advance a material of semifused state into a corner of a blowing mold, and then molding a parison. CONSTITUTION:A material 5 of semifused state is inserted into the corner 4 of a blowing mold 3.

Accordingly, a molded product 7 of uniform thin thickness is obtained on the inner periphery of the mold 3. In this case, the material 5 is the same as the parison 1 and in semifused state. Thus, the material is integrated by the pressure at the blow molding time, thereby obtaining the synthetic resin mold having no boundary.

Title: Voltage stabilizing circuit
Inventor: NAWATA KAZUMASA
IPC: H01L27/06
Filed: 1989-01-10
Abstract: PURPOSE:To simplify constitution and to reduce energy consumption by composing a voltage stabilization circuit by using the two transistors of an NPN transistor and a PNP transistor. CONSTITUTION:A first transistor T1 is the NPN type and a second transistor T2 is the PNP type. Then, at the time of operation, the transistors T1 and T2 are turned to an ON state and a voltage VBE between the base and emitter of the respective transistors is fixed. Accordingly, even when a power source voltage to be added to input terminals 12, 14 and 16 is fluctuated, the inter- terminal voltage of a resistor R2 goes to be the constant voltage VBE and a constant current flows to the resistor R2. Thus, the constant current also flows to the transistor T1 and the voltage between the collector and emitter of this transistor T1 goes to be the fixed value VBE. Thus, this voltage VBE is taken out as a stabilization voltage. Thus, since the number of the resistors and transistors can be reduced, the constitution is made simple and the energy consumption can be reduced.

The ECU 10i reads the accumulated traveled distance via a communication with the respective ECU 10i , and displays it on a display unit. Since reading and writing are not concentrated at the single memory, the memory having high universality can be used.
