Title: Method of sealing heat pipe end
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/02
Filed: 1985-12-03
Abstract: PURPOSE:To seal an end of a heat pipe easily and surely by crushing a small diameter pipe section for sealing that is formed at the end section of a metal pipe by means of a die and a punch of a particular shape with a section of a certain dimension which is not crushed left at the tip end section of the pipe and joining by welding the section of the pipe that is not crushed. CONSTITUTION:One end of a metal pipe such as a copper pipe is sealed and on the other end a pipe section 11 of a small diameter is formed. Non-condensating gases such as air, etc. in the metal pipe 10 are exhausted and a specified working fluid is injected into the inside of the metal pipe 10. The end section 11 of the small diameter pipe is worked to crush it and make the inside faces contact each other with a section 12 of a specified dimension which is not crushed left at the tip end. The crushing work on the pipe end is carried out by pressing radially from outside with a die 13 which has a concave circular face of a specified shape and dimension and a punch the tip end of which is a truncated square pyramid. The metal pipe 10 which has undergone the crushing work is held up right, and the not crushed section 12 left on the end section of the small diameter pipe section 11 is heated to be melted and fused together. With this method, at both end sections in the crushed section where the curvature given by folding is largest has the largest degree of crushing, and as a result no opening caused by the springing back of the pipe material is given, making sure that the press-fusion is obtained.

Abstract: PURPOSE:To perform proper speed change control by changing over a basic speed change characteristic to a backup speed change characteristic at the time of driving a throttle valve through a backup connecting means due to the failure of a throttle control means. CONSTITUTION:At the time of driving a throttle valve 7 by means of an actuator 18, or an electric control system, a control unit 31 sets a basic speed change characteristic in which an engine load, i.e., a throttle opening 34 and a vehicle speed 33 are used as a parameter, as the speed change characteristic of an automatic transmission 2 to perform speed change control. At the time of directly driving the throttle valve 7 through an accelerator pedal via a backup connecting means by disconnecting a clutch 19 due to the failure of this electric throttle control means, the engine load, i.e., an accelerator opening 32 and the vehicle speed 33 are used as a parameter as the speed change characteristic, while setting a backup speed change characteristic which can readily bring about speed change even in the range of a small throttle opening. Thereby, a proper speed change control can be performed in both cases.
