Abstract: PURPOSE:To obtain a flat multilayer wiring by repeatedly constituting a wiring, a connecting column and a wiring. CONSTITUTION:An insulating film 3 is formed onto an insulating film 1. An organic film 6 is coated and changed into a pattern, and the film 3 is removed selectively while using the film 6 as a protective film. A gold film is evaporated onto the whole surface, and the wiring 2 is formed by utilizing the stepped difference of the film 6 and the film 3. The film 6 is removed, and an insulating film 7 is formed. An organic film 8 is coated and changed into a pattern, and the film 7 is removed selectively while using the film 8 as a protective film, thus forming a through-hole 4 at a specific position on the wiring 2. A metallic film is evaporated onto the whole surface in the same manner as the wiring 2 is formed, and the film 8 is removed, thus forming the connecting column 9. A metallic film is coated and changed into a pattern, thus forming the wiring 5. Accordingly, a stepped difference is not formed because the height of the wirings, the connecting column and their peripheral insulating films are approximately equal to each other, and there is no possibility of the disconnection of the upper layer wiring.

Abstract: PURPOSE:To stop incident light as undesired to a light receiver at no testing time with a simple construction by providing a reflector for a tester at a light emitting unit side of a shade to stop incident light reflected at no testing time to the receiver. CONSTITUTION:In testing, a knob 6 is pressed to thereby move the reflecting portion of a reflector 7 toward the end of a shade 4 so at to project the light via the reflector 7 into a light receiver 3. When an alarm is dispatched at this time, it can confirm that a light emitting unit 2 and the receiver 3 and the other componertsare normal in operation. At no testing time the reflecting portion of the reflector 7 is disposed at the base end of the shade 4 to cause the reflected light on the reflector 7 not to be projected into the receiver 3 to thereby produce no error at no testing time to thus enhance the sensitivity. When smoke is existed at no testing time, the light from the unit 2 is reflected and scattered by the smoke and projected into the receiver 3 to generate an alarm.

IPC: B41J2/06
Filed: 1989-05-15
Abstract: PURPOSE:To make it possible to record an image of high quality by setting ink discharge outlets at an interval 1/2 to 2 times the alignment pitch of electrodes for application of an electrostatic field, and forming the electrodes so that the tip of the electrode tapers off toward the opposite electrode end. CONSTITUTION:If an electrostatic field is formed between ink I in the ink discharge outlet 3 of a main head system 4 and an opposite electrode 14, a grown thin, sticky thread of ink reaches a recording sheet 18 and ink dots 26 are formed on the surface. Ink discharge outlets are positioned at so narrow an interval as 1/2 to 2 times the alignment pitch of styli 13, so that the ink I at the base end of the ink thread 25 is controlled and its growth tends to be restricted. However, an electrostatic field F is concentrically formed in a tip part 13a as the tip of the stylus electrode 13 is shaped like R. Consequently, the formation of a single ink thread 25 from the tip part 13a and the subsequent recording of a single dot 26 are ensured. Thus an image of high quality is recorded.

Title: Fuel feed control device for internal combustion engine
Inventor: SHINSHI MAMORU
IPC: F02D41/04
Filed: 1986-05-22
Abstract: PURPOSE:To enable prevention of the occurrence of a fluctuation in an air-fuel ratio due to adhesion of fuel to a pipe wall during transient running, by a method wherein, based on detecting information on parameter correlated to output torque, an air-fuel ratio at each cylinder is estimated to correct a mixture ratio. CONSTITUTION:An in-cylinder pressure sensor 9 detects the combustion pressure of an engine 1 from plural cylinders. In which case, a microcomputer 8 computes parameter correlated to output torque of the engine 1 based on an output from the in-cylinder pressure sensor 9. According to the parameter output, a fundamental fuel feed amount, computed based on an output from a running state detecting means 14, is corrected at each of plural cylinder groups to which fuel is fed at the same timing. Since a difference between an in-cylinder pressure, detected by the in-cylinder pressure sensor 9, and a target in-cylinder pressure is equivalent to an amount of ineffective fuel adhered to and residing at the wall surface of a suction pipe 2, parameter correlated to output torque during transient running is determined to calculate an ineffective fuel content, from which an air-fuel ratio is estimated to corrected a fuel feed amount.

Filed: 1981-07-29
Abstract: PURPOSE:To achieve early stabilization of an ink jet head with forced discharge of bubble therein by setting the excitation frequency thereof to the value at the resonance frequency thereof for a specified time from the starting of the ink drop injection. CONSTITUTION:With the power source ON, a vibrator 2 of an ink jet head is vibrated with a working frequency f0 applied from an excitation driving circuit 3 and jets an ink pillar which is cut to a specified length lb to become ink  drops.
