Title: Method for improving stress corrosion cracking in metal pipe
Inventor: UMEMOTO TADAHIRO
IPC: B23K31/02
Filed: 1989-06-06
Abstract: PURPOSE:To prevent the development of stress corrosion cracking on both surfaces of a metal pipe when inner and outer surfaces of the metal pipe such as stainless pipe are exposed to corrosive fluid by covering welded coupling position in the metal pipe and giving compressive residual stress on the metal surface. CONSTITUTION:By covering the welded coupling 2 position in the metal pipe 1 with a metal sleeve 3, fluid Y in inner part of the metal pipe is prevented from coming into contact with the inner face of the welded coupling 2 and the development of the stress corrosion cracking on inner face of welding coupling 2 is prevented. The surface near the welded coupling 2 eliminates existence of tension residual stress as one of the stress corrosive cracking factor by shifting to direction of the compressive residual stress to prevent the development of the stress residual cracking. Further, in the case of brazing the metal sleeve 3, by giving the temp. Difference between outer and inner parts of the pipe wall by brazing with melding of the brazing filler material 4 and heating the metal sleeve 3 and the metal pipe 1, the stress exceeding the yield point is developed and after that, this is cooled to make under condition of giving the compressive residual stress on the metal pipe surface.

IPC: H04L27/22
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To realize the stable small sized automatic frequency control circuit at a low cost. SOLUTION: Transmission data including error rate measurement data are transmitted and an error rate measurement circuit 7 measures an error rate of the measurement data. An error rate discrimination circuit 8 provides an output of a signal BER-ALM when the measured error rate is a prescribed value or over. This signal passes through a gate 11 to start a pseudo random signal generator 12 when a reception level discrimination circuit 10 discriminates that the reception level is a prescribed level or over. A pulse train outputted from the started generator 12 is given to a D/A converter 13, in which the pulse train is converted into a DC voltage (v) and the frequency of a local oscillation circuit 1 receives random fluctuation.  As a result, when the error rate measured by the error rate measurement circuit 7 reaches a prescribed rate or below, the control above is finished and a carrier with a desired frequency is outputted from a local oscillation circuit.

IPC: H01H33/91
Filed: 1988-06-10
Abstract: PURPOSE:To improve breaking performance by using a movable arcing contact side in a buffer chamber after providing a movable partitioning wall having a communication hole with the chamber. CONSTITUTION:When a movable arcing contact 7 is released from a fixed arcing contact 4 in performing breaking operation, in the case when a breaking current is large, the pressure in insulation gas in a discharge passage rises due to the heat of arc generated between electrodes to compress a partitioning wall 20 to form a hot gas chamber in the case when a breaking current is large. Consequently, insulation gas in the chamber 21 is sprayed onto arc so that it is extinguished. The insulation gas in a buffer chamber 9 pushed out by a piston 17 is thereafter raise the insulation restoring characteristic between the electrodes sharply, and breaking operation is then completed. Since the wall moves in this way, the insulation gas in the chambers 21, 9 is all sprayed onto arc. It is thus possible to improve breaking performance.
