Title: Forming method for pattern by multilayer resist
Inventor: ISOBE YOSHIHIKO
IPC: G03F7/11
Filed: 1987-05-11
Abstract: PURPOSE:To eliminate the steps of coating and baking an intermediate layer and to simply perform the steps by providing a silicon resin layer as a flattened layer on base steps, and forming a photoresist layer thereon. CONSTITUTION:A wiring layer is coated with silicone resin to flatten a base and to prevent the layer from reflecting, and to convert the surface of the resin into SiO2. Irradiation of an ultraviolet ray, O2 plasma processing etc., are effective for this. After it is coated with photoresist 4, a pattern is formed by normal exposure and development, and then the surface layer converted to the SiO2 and an inner lower layer silicon resin are etched by dry etching (O2+CF4 plasma). The SiO2 section of the upper layer becomes a mask at this time. Thus, it can prevent the shape from deteriorating due to random reflection from the base steps to form an ideal photoresist pattern and to simplify the steps.

Abstract: PURPOSE:To make it possible to measure the height of a vehicle to be measured automatically, accurately, highly precisely and safely by arranging plural pairs of light emitting and receiving elements which are provided in the direction of the height of the vehicle in the passing space of the vehicle to be measured so that the elements face to each other. CONSTITUTION:Plural pairs of LEDs 1-11 - 3-1n and light receiving diodes 4-11 - 4-1n are arranged in the direction of the height of a vehicle in the passing space of the vehicle to be measured. A transmission timing circuit 5-2 sequential ly specifies which LED of the LEDs 3-11 - 3-1n should be lit based on a refer ence signal generated from a timing-signal generating circuit 5-1. By the same way, a reception-timing circuit 5-3 sequentially specifies which output signal of the diode of the light receiving diodes 4-11 - 4-1n should be received. The specified 5-2 LED emits light for five cycles based on the modulating frequency from a modulating circuit 507 through a light-emitting-element driving circuit 5-6. Therefore, outputted infrared rays become intense in proportion to the emitted light. Namely, the effect of the disturbance light is hard to receive, and the height of the vehicle can be measured accurately.

Title: Torque detecting device
Inventor: YOKOTA KAZUNORI
IPC: G01L3/10
Filed: 1988-05-10
Abstract: PURPOSE:To measure applied torque without contacting by constituting a driven shaft itself which receives the torque by using a material which has magnetostrictive effect and detecting variation in the magnetic permeability of the driven shaft due to the torque in the form of variation in oscillation frequency. CONSTITUTION:When the torque is applied to the driven shaft 1, the magnetic permeability varies by its magnetostrictive effect. Then when torsional stress is applied to, for example, the driven shaft 1, its magnetic permeability decreases. Consequently, the inductance of a solenoid coil 3 wound around the driven shaft 1 decreases. Then the resonance frequency of this resonance circuit increases and its resonance component is sent to a detection part. The detection part L catches the output signal of the solenoid coil 3 by an input coil 5 and an output coil 6 and outputs it to a waveform shaping circuit N.
