IPC: C23F4/00
Filed: 1986-05-29
Abstract: PURPOSE:To prevent corrosion, by etching an aluminium alloy layer with a resist pattern used as a mask to form an aluminium alloy pattern and heating the substrate while introducing active species for ashing the resist pattern. CONSTITUTION:A substrate 1 is provided by a silicon substrate covered with an insulation layer of phosphorus silicate glass or the like. An aluminium alloy layer 2 of Al-Cu (4%) for example is adhered thereon by means of the sputtering process and a resist pattern 3 is formed thereon by means of an ordinary lithography technique. The aluminium alloy layer 2 is patterned by the reactive ion etching process with the resist pattern 3 used as a mask so as to form an aluminium alloy pattern 2A. The substrate 1 is transported without breaking vacuum and disposed within a microwave downflow asher, so that the substrate 1 is ashed at a temperature of 100-200 deg.C. Thereby, the amount of residual chlorine can be decreased and corrosion can be prevented.

Title: Ultrasonic sensor for vehicle
Inventor: OKAMOTO MINEO
IPC: G01S7/521
Filed: 1993-05-26
Abstract: PURPOSE:To limit the undetectible region. CONSTITUTION:An ultrasonic oscillator 1 is provided with a rain drop detecting section 23. Upon detection of a rain drop, a gate circuit 12 shortens the period of detection gate so that the region close to the ultrasonic oscillator 1 becomes an undetectible region. Consequently, the period of detection gate is not affected by the reverberation of the ultrasonic oscillator 1 even if the duration of reverberation is extended due to adhesion of rain drop. This constitution widens the undetectible region during rain fall but does not widen the undetectible region during other time.

Title: Detecting device for rotating speed of vehicle
Inventor: IKUSHIMA HIROSHI
IPC: G01C21/00
Filed: 1982-07-16
Abstract: PURPOSE:To enable the detection of a speed of rotation wherein an angle of relative rotation from a position of equilibrium can be found, by a simple structure wherein therotation of a rotary body is transmitted to an electrode piece opposed to a fixed electrode piece, and rhe displacement current of capacitor variable corresponding to the rotation of a rotary electrode piece is taken out. CONSTITUTION:The rotation of a rotary body 10 is transmitted to an electrode piece set opposed to an electrode piece set fixed to a vehicle body, by a transmitting means shown by an arrow 20. A variable type capacitor 30 varies its capacity corresponding to the rotation of a rotary electrode piece, and the charge thereof is taken out as a displacement current by a current detector 40. The displacement current passes through BPF 70, gets rid of various voises and undergoes fullwave rectification by a full-wave rectifier circuit 80. Then, it passes through LPF 90 and a signal corresponding to an angle of rotation is taken out. This signal is multiplied by a running speed signal of a running speed signal generating means 100 in a multiplication circuit 110, and is delivered as a signal R. The signal R corresponds to an angular speed of relative rotation of vehicle.

Title: Magnetic disc substrate
Inventor: MAKINO KOUICHI
IPC: G11B5/738
Filed: 1980-09-10
Abstract: PURPOSE:To obtain a substrate which has a high surface hardness and a high surface precision and is adapted for production of a magnetic thin film disc for high- density recording, by providing a titanium nitride or titanium oxide layer on an Al substrate. CONSTITUTION:A titanium nitride or titanium oxide layer is formed on the surface of an Al substrate or an Al alloy plate by the method where titanium nitride or titanium oxide is stuck to this surface directly, the method where Ti is subjected to heat treatment in an atmospheric N2 or O2 at 300-1,000 deg.C after being vapor- deposited, etc. Next, the surface of the formed layer is polished chemically by approximately 1mu to give surface smoothness to surface roughness Rmax 0.02- 0.03mu. Since this polished substrate is not magnetized even if it is subjected to heat treatment at approximately 800-1,000 deg.C, it is subjected to heat treatment at 350 deg.C or less under the state where a magnetic film is caused to adhere onto the substrate. Thus, the substrate is obtained which has a high surface precision and a high surface hardness and is adapted for a thin film disc for high-density recording.

Abstract: PROBLEM TO BE SOLVED: To prevent ashing and creep on he basis of a high temperature, hold a seal function on a high temperature for a long term by fixing a seal material made of a high heat resistance inorganic material on a seal surface of a metallic plate material. SOLUTION: Three metallic plate materials 4 which is, for example, stainless steel and the like, are overlapped, and annular seal materials are fixed in a vertically direction on a position of a half bead 4d around an edge part 4c of an exhaust circulating hole 5 side on a seal surface of a top plate material 4, and on a position of a half bead 4d on the seal surface of a bottom plate material 4. The layer 7 of the seal material is made of a high heat resistance inorganic material. To say concretely, for example, boron nitride scaly particles are mixed with a binding material formed by mixing water glass, surface active agent, and water with each other. Since the particles of boron nitride are used in the layer 7 of the seal material, sealing property can be held for a long period under a high temperature environment exceeding 400 deg.C.  In the case where there are a work blemish and the like on the flange surface, its recessed part is softly buried by the layer 7 of the seal material.

Abstract: PURPOSE:To facilitate separation of a solid and liquid and permit high-load operation by extracting a part of treated water from a supernatant after separation of a solid and liquid above a fluidized bed in a tank, supplying waste water to said treated water after the feeding of oxygen to the treated water outside a system, and recycling this mixture to the center of the tank bottom. CONSTITUTION:Filter material 12 is filled in a fluidized bed septic tank 1, and a part of treated water is extracted from a supernatant after separation of a solid and liquid above a fluidized bed 3 of the tank 1. Oxygen is supplied to the treated water outside a system and bubbles are removed. After this, waste water is supplied to said treated water and this mixture is recycled to the center of the tank 1 bottom to be used as a fluidization source of filter material 12 in the tank 1. That is, a discharge port of circulation piping 4 for fluidization is positioned in the fluidized bed 3 to dispense with a straightening plate so that it is prevented from becoming blocked as a short- coming. Furthermore, the uniform fluidization of filter material 12 in the fluidized bed can be achieved by positioning the discharge port of piping 4 in the center of the tank 1. The above synergetic effect enables easy solid-liquid separation and high-load operation and also miniaturization of the tank 1.
