Title: Temperature control valve
Inventor: ARAI KATSUO
IPC: F16K31/70
Filed: 1982-09-13
Abstract: PURPOSE:To obtain a temperature control valve capable of keeping the temperature of a fluid constant with no use of a temperature sensor, a thermostat or the like, by providing a resilient means made of a shape memory material which operates to move an inner cylindrical member in a fluid valve in response to change of the fluid temperature. CONSTITUTION:A resilient means 3 is made of a shape memory material of a Ni-Ti alloy and it is formed into a helical spring at the room temperature under the state that no tension is applied thereto. The resilient means 3 is expanded when the temperature is higher than 60 deg.C and contracted when the temperature is lower than 60 deg.C. Another resilient means 4 is manufactured with application of tension at the room temperature. It is contracted when the temperature is higher than 60 deg.C and expanded when the temperature is lower than 60 deg.C. When the temperature of oil in a tank becomes higher than 60 deg.C, heat is transmitted to the springs 3, 4 respectively from good heat conductors 8a, 8b, so that the spring 3 is expanded while the spring 4 is contracted. Resultantly, an inner cylindrical member 2 is moved to the right in the drawing and an oil inlet passage 5a is closed while another oil inlet passage 5b is fully opened, so that only oil of a temperature lower than 60 deg.C is supplied to the tank. On the other hand, when the temperature of oil in the tank becomes lower than 60 deg.C, the inner cylindrical member 2 is moved to the left, so that oil of a temperature higher than 60 deg.C is supplied from the oil inlet passage 5a.

IPC: G01J5/02
Filed: 1986-07-08
Abstract: PURPOSE:To estimate the temperature of a body to be measured and a black body which is connected thermally thereto with high accuracy by separating and extracting only heat radiant light from the body to be measured and black body from disturbing light, and measuring its spectrum and intensity. CONSTITUTION:Gas and plasma 2 is confined to a container 1 and the black body 3 and a 1st polarizer 17 close to it are arranged in the container 1. The heat radiant light from the black body 3 is polarized by a polarizer 17 into linear polarized light which has its plane of polarization converted to a specific direction and this polarized light travels to an optical analyzing device 6 through the window 4 of the container 1. A 2nd polarizer 18 is provided in front of the photodetection part of the device 6 and the heat radiant light 19 and light 7 are incident on the polarizer 18. The transmissivity of the polarizer 18 to the heat radiant light 19, on the other hand, is maximum when the center axis of the polarizer 18 is parallel to the paper surface and zero when the center axis is perpendicular to the paper surface. For the purpose, the polarizer 18 is so set at positions where the center axis is parallel and perpendicular to the paper surface, and the difference of transmitted light between the positions is found to analyze the spectrum and intensity, thereby correctly estimating the temperature of the black body 3.

Title: Check valve for automatic chemical analyzer
Inventor: MAI AKIRA
IPC: G01N35/10
Filed: 1989-06-22
Abstract: PURPOSE:To prevent the adverse influence on the discharge accuracy by rubber valves by providing a dual check valve set higher in the hardness of the section side rubber valve than the hardness of the discharge side rubber valve. CONSTITUTION:Pressure is applied gradually on the suction side rubber valve 18a as a syringe 20 rises at the time of discharge. The valve 18a has the high hardness and the discharge side rubber valve 18b is formed easily deformable so that the flow of liquid is only from the valve 18b. Backflow does not, therefore, arise on the suction side and the liquid is discharged at a desired rate from the nozzle 22 for discharge connected to a discharge port 17c via the valve 18b of the low hardness. The valve 18a is not reset upon ending of the rising operation of the syringe 20. The discharge of unnecessary drops from the nozzle 22 is consequently prevented.
