Title: Frequency division device of ac current
Inventor: MASAKI KAZUMI
IPC: H02M1/08
Filed: 1984-08-18
Abstract: PURPOSE:To obtain an AC current with a low frequency by rectifying an AC voltage, applying it to a circuit having a time constant, driving a thyristor at each prescribed time and applying a half cycle or plural cycles of AC currents to a load. CONSTITUTION:A capacitor C is charged from an AC power supply AC through a diode D1 and a time constant resistor R1. The integration voltage waveform charged to the capacitor C rises stepwise by the time constant comprising the capacitor C and the resistor R1. When the charging voltage of the capacitor C reaches a prescribed value, a voltage of prescribed value is applied to a constant voltage diode J decided by the ratio of voltage dividing resistors R4, R5 and the discharge element is made conductive through a resistor R3. A thyristor SCR2 is conductive by a voltage drop across the resistor R3 and the electric charge in the capacitor C is discharge instantly through the resistor R2. The voltage generated by the discharge current makes the thyristor SCR1 conductive, then a current flows to a load Z and an AC current with a low frequency is obtained.

Title: Complex clutch type speed change gear
Inventor: AKUTAGAWA HITOSHI
IPC: F16H3/08
Filed: 1982-09-29
Abstract: PURPOSE:To improve traveling performance, drive feeling, and meandering fuel consumption efficiency by installing a unidirectional clutch between a speed change gear for the first speed advance and an output shaft, thus permitting predetermined traveling and eliminating the shock in speed change to the second speed. CONSTITUTION:A unidirectional clutch 29 operates in the first speed advance, and the first speed cone part 23e of an inner lace is engaged with the flange part 10d of the first speed gear 10 of an outerlace and revolved in the reverse direction to the engine revolution. In the speed change from the first speed advance to the second speed, the revolution number of an output shaft 9 increases through disconnection of the first clutch 7 and connection of the second clutch 18, and the power is transmitted from a sleeve 23a to the cone part 23e. The unidirectional clutch 29 does not operate, since the revolution number of the cone part 23b which revolves reversely to the engine is larger than that of the flange part 10d which revolves in the same direction and the cone part 23e is idle- revolved, and the power is not transmitted to the gear 10. Therefore, the first input shaft 2 continues smooth revolution, and shock is not generated. In meander traveling, reverse transmission of power is suppressed similarly, and fuel consumption efficiency can be improved.

Inventor: SHIMADA MUTSUMI
IPC: G03G9/08
Filed: 1989-07-06
Abstract: PURPOSE:To accomplish high image resolution, to give high density and to obtain a stain-free image excellent in reproducibility in a non-image part by specifying the press-contacting force of an elastic cleaning blade to a photosensitive body and the property of toner used in an electrophotographic copying device provided with the elastic cleaning blade which press-contacts to the photosensitive body to remove residual toner. CONSTITUTION:In the electrophotographic copying device using a photosensitive body and cleaning device integrated unit obtained by fixing the photosensitive body 1 in the part of a cleaning device, it is assumed that the press-contacting force of the cleaning blade 2 to the photosensitive body is 25-45g/cm, desirably 30-40g/cm. In the case of using the toner whose volume means grain diameter is 5 to 10mum and whose triboelectrification quantity is -15 to -35muc/g, when the press-contacting force is more than 45g/cm, friction between the photosensitive body and the blade increases and the deterioration of the material of the blade and the scratch of the photosensitive body by long usage and the change of environment, etc., are caused, then the lives of the blade and the photosensitive body are shortened. On the contrary, when the press-contacting force is less than 25g/cm, the scraping ability of the cleaning blade is remarkably deteriorated to cause the fusion, etc., of the toner which passes through the press-contact edge of the blade.
