Filed: 1979-07-03
Abstract: PURPOSE: To make it possible to cover request range ability 40 of a flow rate sufficiently by making possible a flow-rate control range 0W100% in terms of time width by arranging two cross valves in the fluid passage of a control system for phase control over on-off operation.  
     CONSTITUTION: At the halfway points of fluid circuit control system passage 10, ducts 11 and 12 with shunt point 13 and conflux point 14 are provided and at shunt point 13 and conflux point 14, cross valves 15, 15 are provided respectively. The injection time width can be controlled from zero to a continuous flow by bringing solenoids 18, 18 of those two cross valves 15, 15 under phase control. Namely, a small flow rate can be obtained by operating the cross valves 15, 15 with relative phase θ close to 20ms as shown in fig. 2A and a larger flow rate can be obtained as relative phase θ is made closer to zero as shown in fig. 2B. Shifting θ up to its limit makes it possible to adjust the amount of injection 0W100%. Therefore, request range ability 40 of an engine can sufficiently be covered.

Title: Silicon etching process
Inventor: IKEDA KYOICHI
IPC: H01L21/3065
Filed: 1985-04-22
Abstract: PURPOSE:To augment the etching rate enabling to perform a selective etching process stably at a p-n junction by a method wherein a silicon wafer with a p-n junction is immersed in a fluoric acid solution or a mixed solution of fluoric acid to apply a voltage to the junction of p layer and n layer of the silicon wafer. CONSTITUTION:A fluoric acid solution or a mixed solution of fluoric acid is used as a solution for immersion while a negative voltage impressed on platinum electrode is connected directly to the p layer side of a silicon wafer. The current of positive electrode impressed on the n layer side begins to flow from the n layer into the fluoric acid solution while a product 10 due to anode current formed on the surface of n layer flows to the p layer on the negative electrode side. Resultantly, the anode current flows into fluoric acid solution from the n layer only never from the p layer. Besides, the product 10 can be removed easily by fluoric acid solution to make continuous etching process feasible.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To exhibit high toner carrying out capacity while insuring stable cleaning function even in the case of lowering fluidity of toner by providing a toner carrying out mechanism carrying out toner outward, and providing a deformation member reversibly deformed by temperature in the vicinity of the carrying out mechanism. SOLUTION: Transcription residual toner on a photosensitive drum 1 is scraped out by a cleaning blade, and it is carried to a doctor roller 9-6 side by rotation of a cleaning roller 9-5. The toner is dammed up by a toner buffer member 9-8 to retain, then it falls toward a toner carrying screw 9-4 from the gap. The toner buffer member 9-8 is tiltably supported with a post 9-7 through a deformation member 9-11 reversibly deformed by temperature. When the atmospheric temperature exceeds 40 deg.C, the toner buffer member 9-8 changes the angle in the vertical direction, as a result, toner retention increases, to prevent bridging of the toner from generating.
