Title: Gas flow rate control valve for extremely low temperature
Inventor: MATSUI AKIHIKO
IPC: F16K31/06
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To keep slide faces of a poppet and a sleeve in a condition in which they can slide smoothly at all times and enable the use of a gas flow rate control valve even in extremely low temperature environment. SOLUTION: A poppet 1 and a sleeve 2 are made of nickel group alloy. By forming a hard and thin film 6 of titanium nitride on a surface of the poppet 1 which slides with the sleeve 2 by ion plating method, it is possible to prevent a seizure (adhesion) of the slide face of the poppet 1 and the sleeve 2 and reduce friction coefficient. Moreover, it becomes possible to reduce friction coefficient further by forming a thin film of molybdenum disulfide on the surface of the poppet by sputtering method. Furthermore, it is possible to improve the service life of the slide face further by forming the hard and thin film of titanium nitride on the surface of the poppet and forming the thin film of molybdenum disulfide on it.

Title: Resistance adjusting method for thick-film resistance element
Inventor: KANEDA ISAO
IPC: H01C17/22
Filed: 1984-12-26
Abstract: PURPOSE:To accomplish high-precision, high-reliability adjustment toward decreasing the resistance value of a thick-film resistance element, once subjected to a baking process, by a method wherein a DC voltage is applied across both ends of the once- baked thick-film resistance element and the current generated by the voltage is subjected to measurement during the application of a beam to raise the temperature of the resistance element. CONSTITUTION:A voltage is applied to a trimming laser 7 for increasing the resistance of a resistance element 2 or 8 positioned on a substrate 1 or for a beam 4 for decreasing the resistance of the same. The mechanism is so arranged as to determine the value of resistance by measuring the current generated by an applied voltage whereunder the value will increase or decrease. A DC voltage out of a power source 5 is applied across conductors 3 made of silver-palladium or the like connected to both ends of the thick-film resistance element 2. The resistance presented by the resistance element 2 is determined by measuring the current through the resistance element 2 by means of the ammeter 6. The elevated temperature attributable to the resistance- decreasing beam 4 thrown upon the element 2 causes silver out of the silver-palladium combination constituting the electrodes 3 to diffuse into the resistance element 2, which decreases the resistance to a target value.
