Filed: 1988-08-10
Abstract: PURPOSE:To drive rotation efficiently by controlling power supply to each set of coil at stator section such that at least one set of coils or plural sets of coils are fed simultaneously with power corresponding to a predetermined switching operation. CONSTITUTION:When a motor is rotating with low speed, a switching control transistor TR 14 and a switching drive transistor TR 15 are turned OFF. Front stage transistors TR1-TR3 and rear stage transistors TR4-TR6 are turned ON/ OFF sequentially through a three-phase logic circuit L and power is fed to every two sets of coils thus rotating a rotor magnet. When the motor is rotating with high speed, the switching control transistor TR14 and the switching drive transistor TR15 are turned OFF, and thereby the control transistors TR11-TR13 are turned ON while the front stage transistors TR1-TR3 are turned OFF. The three-phase logic circuit L feeds power to every set of coils end rotates the rotor magnet.

Title: Disintegrating disposer of waste dry cell
Inventor: KUSAKABE TOSHIO
IPC: B09B5/00
Filed: 1986-08-25
Abstract: PURPOSE:To enable a dry cell to be disintegrated completely without spilling the contents by disposing the dry cell thrown between bilateral vertical-type rolls so that the dry cell may be deformed to be disintegrated by a rotary squeezing pressure of the rolls. CONSTITUTION:A dry cell 4 thrown vertically through a chute 5 enters from the upside between unidirectionally rotating vertical-type rolls 7(1), 7(2) driven by power 8, and moves downward between the roll axes 7a, 7b while rotating in a direction opposite to the rotating direction of rolls by coming into contact with rolls 7(1), 7(2). Since both of the verticaltype rolls 7(1), 7(2) are tapered off upward, a gap between them are formed to be adversely tapered downward. Accordingly, as the dry cell 4 moves downward along the gap between vertical- type rolls 7(1), 7(2), a rotary squeezing pressure is increasingly applied to the dry cell causing its gradual deformation and eventually instantaneous disintegration at an upward constriction part between rolls 7(1), 7(2), while releasing a metal cap from an expanded exterior metal cylindrical plate and dropping contents such as carbon rod, zinc can and graphite through it.

Filed: 1989-08-02
Abstract: PURPOSE:To efficiently remove remaining toner and to stably obtain a large number of high-quality copies free of base soil by employing cleaning carriers containing photoconductive material as a cleaning agent accommodated in a magnetic brush cleaning part. CONSTITUTION:For the cleaning agent accommodated in the magnetic brush cleaning part 7, the cleaning carriers containing the photoconductive material is employed.

By utilizing the feature of the carriers that when light irradiates the photoconductive material, the carriers lower resistance, the resistance can be dropped. Thus, remaining toner is effectively removed, a large number of high- quality copies can be stably obtained.
