Title: Exposing dry plate
Inventor: SUMI KAZUHIKO
IPC: G03F1/00
Filed: 1988-03-08
Abstract: PURPOSE:To accurately transfer a pattern, when a subreticule or a submask is made through contact exposure by forming an antireflection film on the peripheral part of a pattern forming metallic films, as well. CONSTITUTION:The pattern forming metallic film 2 is formed on the surface of a transparent substrate 1, and the antireflection film 3 is formed on the surface of the pattern forming metallic film 2. Therefore, the pattern forming metallic film 2 is not exposed in the peripheral part 4 but covered with the antireflection film 3. Accordingly, when the subreticule or the submask is made by a contact exposure system, multiplex reflection does not arise in the peripheral part 4 of a pattern. Thus, the pattern is accurately transferred.

Title: Turbine flowmeter
Inventor: NAGAYAMA SENGOROU
IPC: G01F1/115
Filed: 1989-03-07
Abstract: PURPOSE:To omit electric power in integration and holding and to make it possible to perform remote measurement through communications circuits by a constitution wherein the integral number of rotations of a blade wheel at the position of magnetic bubbles is detected. CONSTITUTION:A magnetic bubble element 13 sequentially transfers magnetic bubbles in response to the rotation of a magnetic field. The element 13 is arranged in the vicinity of a permanent magnet 12. When the permanent magnet 12 is rotated together with a rotary shaft 11, a rotary magnetic field is applied on the magnetic bubble element 13, and the magnetic bubbles are transferred in the magnetic bubble element 13. When the number of the poles of the permanent magnet 12 is two, the magnetic bubble in the magnetic bubble element 13 is shifted by one step on the transfer pattern when the rotary shaft 11 is rotated by one rotation. When the position of the magnetic bubble on the transfer pattern is detected, the number of rotations of the rotary shaft 11 can be found. That is, the integration of the flow rates can be performed without using electric power.

Title: Detecting circuit of resistance temperature characteristic
Inventor: NONAKA KENJI
IPC: G01K7/24
Filed: 1988-03-07
Abstract: PURPOSE:To make a circuit configuration small and simple, by providing a resistance temperature measuring circuit having a number of channels and by enabling the execution of correction by one resistance temperature detecting circuit. CONSTITUTION:Outputs (called channels 1-N) of resistance-value/voltage conversion circuits 11-1N are inputted to a multiplexer 2, and one of the voltages of the channels 1-N is selected sequentially by a control signal and taken as an input voltage of an A/D converter 3. Based on a reference voltage Vref denoted by 5, the converter 3 converts an output voltage from the multiplexer 2 into a digital signal and outputs same. In an arithmetic circuit 4, an input voltage varying with a temperature variation rate of a resistance is given from the multiplexer 2 and amplified by arithmetic units H41 and H42. As an output of this circuit, a voltage having a temperature variation rate the value of which is made small by offsetting the temperature variation rate of the resistance is generated and inputted to the converter circuit 3, and thereby a digital signal proportional to a temperature is outputted therefrom. Thus, the output of the converter 3 turns to be a voltage being proportional linearly to the variation of the temperature.
