Title: Treatment for preventing stress corrosion cracking of austenite type stainless steel
Inventor: FUKUSHIMA EIJI
IPC: C21D7/02
Filed: 1981-06-02
Abstract: PURPOSE:To prevent stress corrosion cracking of austenite type stainless steel in environment with high chloride concn. by a method wherein austenite type stainless steel is cooled to a room temp. or less and stress equal to or lower  than yield strength is acted thereon to make a part of metastable austenite  martensitic. CONSTITUTION:Austenite type stainless steel such as 18Cr-8Ni steel or the like is immersed in a cryogen such as liquid nitrogen or the like to be cooled to a room temp. or less. Load is applied to the desired part or all of this steel to tenerate stress including shear stress as a component. During this treatment, at least a part of metastable austenite contined in this stressed part is transformed to disperse and form martensite structure in steel. This martensite prevents the breakage of a protective coating due to rough sliding of a steel surface which is the cause of stress corrosion cracking and the generation of stress corrosion cracking under environment with high chloride concn. is prevented.

Abstract: PURPOSE:To easily transfer an extension telephone set from another key telephone set of the same classification by constituting a key telephone system so that an extension terminal equipment communicates information with a host device while indicating the password code sent from the host device and the extension number code to the host device. CONSTITUTION:In a key telephone system 1, the password code peculiar to a host device 7 is sent from the host device 7 to extension terminal equipments 8 to 10, and each extension terminal equipment stores and holds the password code sent from the host device 7 together with the extension number code and communicates information with the host device 7 while indicating the password code and the extension number code to the host device 7, and the host device 7 discriminates whether the password code sent from the extension terminal equipment and the peculiar password code coincide with each other or not. Thus, though a terminal equipment is transferred from another compatible host device, the host device can immediately recognize transfer from another host device without mistaking this transfer for internal transfer and the processing suitable for the case is automatically performed.

Filed: 1989-04-05
Abstract: PURPOSE:To facilitate smooth inverter control responding to the use situation of a compressor by arranged to control an inverter with data of piston displacement of a suction throttle valve which opens/closes by means of a pressure adjusting valve that operates with the pressure in the downstream of an oil separator. CONSTITUTION:When the quantity of air used is large, the pressure inside a discharge pipe 17 is low and the pressure inside an unload pipe 19 is 0, and the piston of a suction throttle valve is lowered till the lowest end by the force of a spring 3, and the suction throttle valve is in the fully opened state. And, when the quantity of air used becomes small, the pressure inside the pipe 17 gradually rises and the pressure in the downstream of a pressure adjusting valve 19 is raised. For that reason, the piston 4 of the suction throttle valve begins to move upward little by little by this pressure. And, when the quantity used becomes 0, the piston 4 moves till the highest end to fully open the suction throttle valve. The data that sensed the position of this piston by a displacement sensor 33 is sent to a microcomputer 27 to prepare the data that can be inputted to an inverter 29, and perform the rotation speed control of a motor 13 by the inverter 29.
