Filed: 1989-05-12
Abstract: PURPOSE:To uniform and supply toner in a dispersed state by vibrating a toner conveyance member, which has a wedgelike toner conveyance surface narrowing down gradually in the conveyance direction of time, by an exciting means and conveying the toner toward the acute-angle tip part. CONSTITUTION:The toner 9a which is supplied from a toner supply opening 11 falls on the rear end part 22 of a toner conveyance member 2 arranged right below the supply opening 11. The conveyance member 2 is vibrated through the operation of the ultrasonic wave generator of the exciting means 3. The toner 9a which falls on the rear end part 22 of the toner conveyance member 2 by the vibration is conveyed on the toner conveyance surface 23 toward the tip part 21. The toner 9a conveyed on the conveyance surface 23 reaches the end earlier and earlier as it is conveyed more and more outside on the conveyance surface 23 because the conveyance surface 23 is in a wedgelike shape and narrows down gradually in the toner conveyance direction. The toner 9a which reaches the end falls from both sides of the conveyance surface 23 while dispersed more thinly by the edge. Consequently, the toner 9a is uniformed and supplied while dispersed little by little in the conveyance direction of the conveyance direction 23.

Title: Vapor growth method
Inventor: FUKASE KENJI
IPC: H01L21/86
Filed: 1987-05-15
Abstract: PURPOSE:To deposit a uniform and high-quality film, by transporting a source gas to a substrate only after several conditions of film formation are satisfied. CONSTITUTION:For a prescribed period prior to vapor growth, a by-pass gas is made to flow across a downstream side of a transport pipe so that the source gas does not go out of the transport pipe. Namely until production of the source gas is stable, the by-pass H2 gas is introduced from a by-pass gas introducing port 12. Then the by-pass gas forms a flow of gas across the inside of the transport pipe 6, and the source gas is guided to a second opening 15. An AlCl gas, the source gas, a HCl non-reactive gas, and the like are made to attain to an exhaustion port 11 of a reaction tube from a third opening 17 which is located on the downstream side of a substrate locating part, through a by-pass gas exhaustion pipe 16. After the source gas is produced on a stable state, the introduction of the by-pass H2 gas is stopped or reduced, and concurrently a CO2 gas is introduced from a gas introduction port 10. An Al2O3 film which is uniform and has no impurity from the beginning of this piling process can be formed on a Si substrate 9.

Title: Capacity controlling method for displacement type multi-stage compressor
Inventor: MORIKAWA HISAKUNI
IPC: F04C28/02
Filed: 1981-07-30
Abstract: PURPOSE:To achieve ecomonical operation of a compressor, by restricting the opening of a throttle valve to a tolerable minimum degree according to the actual operational conditions of the compressor, and thereby enabling to recover the driving power. CONSTITUTION:Output signals of two calculators 8a, 8b are applied to a first selector 9. When either of the output signals has reached a critical value, the ''critical value'' signal is applied to a second selector 10 provided in a displacement signal system. Further, when the critical value is applied to the second selector 10, the opening of a throttle valve 3 is fixed by holding the signal produced by pressure detector 5. Resultantly, the throttle valve 3 is closed on the basis of the output signal of the pressure detector 5 until the ''critical value'' signal is afforded to the second selector 10. Thus, since the throttle valve 3 is closed to a tolerable minimum degree, it is enabled to recover the driving power.

Title: Image forming device
Inventor: NODA NOBUTAKA
IPC: G03G21/14
Filed: 1995-04-24
Abstract: PURPOSE: To always keep sufficient fixing characteristic without being influenced by environment and to form an image in the best condition by prolonging an interval time for when the surface temperature of a heating body is lower than a second set temperature. CONSTITUTION: The surface temperature of a heating roller is returned so as to be always positioned inside fixable areas (T1, T2) by means of the previously set interval (ta), even though the image is consecutively formed as shown in figure (A) in the case of normal temperature. In the case of a low temperature environment, the interval is prolonged to previously set time (tb) by means of a control circuit when the surface temperature of the heating roller is lower than second set temperature Tp as shown in figure (D). The temperature of the heating roller rises to first set temperature (ts) or to the temperature which is not <=T1 by the idly driving of the heating roller even though next image forming is performed in the middle of interval. Thus, the next image forming is performed after the surface temperature of the heating roller rises.
