Filed: 1988-05-11
Abstract: PURPOSE: To obtain a small and highly efficient low price brake unit by an arrangement wherein a winding is fed with a required DC current from a rectifier bridge being formed under brake state through electric control from the thyristor of a voltage converter. CONSTITUTION: Magnitude of a DC current Udc being fed from a power supply is controlled separately by interrupting current supply to a DC power supply using pairs of thyristors T3, T6 and T7, T10. At the time of brake operation, current supply to a motor 1 is interrupted by turning all thyristors off.

Filed: 1983-06-24
Abstract: PURPOSE:To selectively remove an impurity without using a special mask by ion implanting the prescribed impurity atoms in an impurity diffused region by utilizing the difference of oxidized films formed by simultaneously oxidizing at least two impurity diffused regions of different densities formed on a semiconductor substrate. CONSTITUTION:A buried layer 5 and an N type epitaxial layer 6 are formed on a P type semiconductor substrate 10 of silicon single crystal to isolate between elements by an isolation region 7, therby diffusing a base region 2, an emitter region 3 and a collector region 4. Then, contacting holes 2a, 3a, 4a are respectively formed on the regions 2, 3, 4. Then, an oxidized film 8 of an SiO2 is regrown by using an oxidizing step. Since the film 8 varies in its growing speed according to the impurity density, the region 3 having higher density by ten times order forms the film 8 thicker than the region 2. After the oxidizing step, boron ions are not almost implanted to the contacting hole 3a due to the difference of the thickness of the oxidized films at this time.

Title: Electrophotographic copying device
Inventor: KAWANO YUZO
IPC: G03G15/08
Filed: 1988-05-10
Abstract: PURPOSE:To effectively utilize the capacity of a toner hopper by forming higher and lower parts on the bottom of the toner hopper, providing a toner discharge port and a discharge roller on their boundary and cross-sectionally providing an agitating member thereon. CONSTITUTION:In the toner hopper 9, a toner 8 is initially in a condition shown by line F. The same time that a toner discharge roller 14 rotates owing to the driving force of a driving source, a rotating shaft 17, and sprockets 18a and 18b rotate. Together with the rotation, the agitating member 20 crosses the upper part of the toner discharge roller 14 from the lower bottom of the hopper 9 and moves along the higher bottom while ascending. The toner 8 is agitated and pushed toward the discharge roller 14. When the toner 8 decreases to expose the discharge roller 14, accelerating speed is applied to the toner attaching to the agitating member 20 and tends to fall down because the toner around there rises. Much of the toner drops above the discharge roller and seldom passes; therefore the quantity of the toner residing in the hopper decreases to effectively use the capacity of the toner hopper.
