Title: Gas flow rate measuring device
Inventor: KAWAI HISASHI
IPC: G01F1/68
Filed: 1978-12-27
Abstract: PURPOSE: To obtain a measuring device with less affection of a drift by differentially amplifying a sampling voltage and a reference voltage only while synchronizing a pulse signal of the oscillating circuit.  
     CONSTITUTION: The electric heater 10, first and second temperature dependency resistances 11, 12 are provided in the flow rate measuring tube 9. When the suction air increases, the voltage across the points a, b of the bridge 50 drops, and the output voltage V 2  of the sampling hold circuit 76, which samples the value of said voltage by means of a pulse signal of the oscillating circuit 45, drops too, the difference between the said voltage V 2  and the constant voltage V r2  of the voltage generator 25 becomes greater. As a result, current to the electric heater 10 increases, temperature of the suction air rises. Since the current in the electric heater 10 increases until the relation V 2 =V r2  holds, the quantity of suction air can be measured by measuring the current flowing in the electric heater 10 by means of the current detecting circuit 100.

Title: Carbon-metal composite material
Inventor: KANO MASATO
IPC: B60L5/24
Filed: 1989-06-26
Abstract: PURPOSE:To provide a carbon.metal composite material having an excellent flexural strength, etc., and reduced in the generation of breakage, etc., by compounding metallic fibers in a carbon raw material in a state oriented in one direction, the surfaces of the metallic fibers being partially or wholly coated with a different kind of a material. CONSTITUTION:The surfaces of metallic fibers (e.g. steel fibers) and preliminarily coated with a coating layer of a material (e.g. copper or nickel) slightly impregnated with carbon by a plating method, a vacuum-depositing method, etc. The coated metallic fibers are mixed with a carbon raw material (e.g. a phenolic resin) and oriented in one direction. The mixture is molded and carbonized by a conventional method to prepare a carbon.metal composite material. A method for orienting the metallic fibers in one direction includes a method in which the metallic fibers are oriented in one direction under a magnetic field of several ten thousand gauss. Since a carbon impregnation reaction in the metallic fibers is thereby sufficiently controlled in the carbonization process, the prepared composite material has an excellent flexural strength, etc., and is suitably used for pantograph sliding plates for railways, etc.
