Title: Substrate end face treating apparatus of organic photoreceptor producing apparatus and organic photoreceptor as well as its production
Inventor: MORITA TATSUHIRO
IPC: G03G21/10
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To form images which are decreased in defects by preventing the peeling of the unnecessary coating film formed on the outer peripheral surface of a substrate end face constituting an organic photoreceptor and the residues adhered thereto. SOLUTION: A solvent 33 in an auxiliary tank 38 is supplied to a solvent tank 32. The bottom end of the cylindrical conductive substrate 36 constituting the organic photoreceptor may be immersed into the solvent 33. The coating film for a photosensitive layer is formed on the outer peripheral surface of the substrate 36 and the unnecessary coating film at the bottom end of the substrate 36 is dissolved and wiped. The solvent 33 is capable of dissolving the coating film and particularly a resin soluble in the solvent 33 is incorporated therein. A blade 34 may be brought into abutment on the bottom end face of the substrate 36. The relative relation between the liquid surface of the solvent 33 and the height of the blade 34 is adjustable.  The upper front end of the blade 34 is set higher than the liquid level of the solvent 33 in a substrate end face treatment stage and is set low in a residue coating treatment stage. Since the unnecessary coating film is wiped by the resin-containing solvent 33, the peeling may be prevented by covering the substrate end face adhered with the residues with the resin film.

Title: Engine control device
Inventor: SAKAKIBARA NAOJI
IPC: F02D23/02
Filed: 1983-06-23
Abstract: PURPOSE:To secure safety of a vehicle and indicate a control condition of an engine, by detecting a turbocharger operation through a plurality of pressure detection means to energize a fuel supply mechanism, and providing an indication means operable according to detected pressures. CONSTITUTION:Both of pressure switches PS1 and PS2 are closed upon rapid acceleration to an extent greater than a predetermined level, and a solenoid of a relay RL1 is energized to go on and thereby to energize a fuel injector 10. Accordingly, fuel is injected and an engine output is increased to rapidly accelerate a vehicle. In other words, only when an acceleration condition to an extent greater than a predetermined level is detected, a supercharged pressure is increased over a predetermined level for a predetermined time to operate the injector 10 and supply an additional fuel to increase the engine output. When a turbocharger is operated, a vacuum in an air intake pipe 5 is decreased, and a contact point of the switch PS1 is closed to apply voltage to light emission diodes LE1 and LE2, thereby emitting a green light, where the diode LE2 is in an OFF condition. Thereafter, when the output is further increased and the pressure in a tank 9 exceeds P1, the contact point of the switch PS2 is closed to energize the diode LE2, thereby emitting a yellow light and indicating a control condition of an engine.

Title: Fluid pressure sensor
Inventor: HIROTA HISATOSHI
IPC: G01L9/04
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain a fluid pressure sensor in which the production costs of a ceramic disk pressure-receiving member can be reduced by a method wherein the ceramic disk pressure- receiving member is arranged so as to be brought into close contact with the rear of a flexible thin film in which a fluid pressure is received on its surface, resistors whose electric resistance value is changed due to a strain are bonded to both faces of the pressure-receiving member and the fluid pressure is detected on the basis of a change in the electric resistance value. SOLUTION: A connecting hole 2 which is connected to a refrigerant flow passage is formed in the tip of a metal pressure-receiving-part housing 1. The pressure of a refrigerant which is introduced into a pressure-receiving space 4 via a communication hole 3 is applied to the surface of a pressure-receiving plate 10 via a diaphragm 6, and the pressure-receiving plate 10 is bent. Then, an electric resistance piece on the surface of the pressure-receiving plate 10 is shrunk, and its electric resistance value is reduced. At the same time, an electric resistance piece on the rear of the pressure-receiving plate 10 is extended, and its electric resistance value is increased.  On the basis of an output voltage value, from contact pins 14 based on a voltage across terminals in a second through hole and a fourth through hole, which is changed due to the electric resistance value, the pressure of the refrigerant which is applied to the pressure-receiving plate 10 can be detected. Since the pressure-receiving plate 10 is pressed and molded to the rear of the diaphragm 6 as a flexible thin film, a fluid pressure sensor can be manufactured at very low costs.

Filed: 1980-08-18
Abstract: PURPOSE: To form fine needle ferrite in weld metal and improve the toughness of weld metal by adding a specific amount of synthesized TiO x  of which the range of X is limited to a low hydrogen covering material.  
     CONSTITUTION: If artificially synthesized TiO x  of which the X is in a 0.65W1.3 range is added at 0.1W5% by weight % to a covering material, the grating constants of the TiO x  well match the grating constants of α iron, and the nucleus formation of needle ferrite at the interface of the ground metal and the TiO x  occurs easily. However, with other Ti type oxides, TiO 2 , Ti 2  O 3 , Ti 3 O 5  and other  oxide Al 2 O 3 , there is not matching characteristic of the gratings and needle ferrite is not formed. Next, with regards to the amount of addition, needle ferrite will not be formed if the TiO x  is added at 0.1wt%, and if it exceeds 5wt%, the viscosity of slag increases, resulting in degraded welding workability.
