Title: Temperature measuring method for magnetic bubble element
Inventor: UCHISHIBA HIDEMARO
IPC: G01K7/00
Filed: 1978-12-15
Abstract: PURPOSE: To secure the high-accuracy monitoring for the temperature change of the magnetic bubble element by installing the magnetic bubble detector on the bubble element according to the magnetic pattern and then flowing the current to the detector for measurement of the voltage change at the both ends of the element.  
     CONSTITUTION: The current I 1  and I 2  are flowed to detection patterns 31 and 32 of detector 3 for the magnetic bubble element consisting of major loop 1 and minor loop 2, and the overlap voltage +V is detected by the high-accuracy voltmeter connected to terminal 34. The permalloy composing patterns 31 and 32 features a high temperature coefficient, and the voltage change is linear to the temperature when a fixed level of current is flowed. In this connection, the temperature is measured via the temperature change of the resistance. Thus no special unit is provided for measurement, and the current source used at the detection time of the magnetic bubble is also used. Furthermore, detection patterns 31 and 32 adhered to the chip are used, and as a result the accurate measurement becomes possible compared with the conventional method in that the thermocouple is provided near the chip.

Title: Out-of-roundness correcting method for end of piping
Inventor: SHIMAGUCHI TAKASHI
IPC: B21D1/08
Filed: 1981-10-02
Abstract: PURPOSE:To correct out-of-roundness of a pipe of unknown material strength at high  accuracy and with minute pipe expanding by providing a displacement meter in the  circumferential direction of the end part of piping and determining yield load of the  pipe from expanding load and displacement of the pipe during pipe expanding. CONSTITUTION:Signals from sensors 8 installed at four places in the circumferential  direction of a pipe 14 are received by an arithmetic section 9, and the initial shape of  the pipe 14 is stored in a memory section 10. When a piston 12 is pulled by a hydraulic power source 11, the internal pressure is generated in the pipe 14, and the load and  displacement of the pipe 14 are recorded in a recording section 10 by the arithmetic  section 9 in terms of relation between the load and displacement. In repeating this  operation, a time comes when a fixed proportional relation between the load and  displacement of the pipe 14 is lost as the internal pressure grows larger. This load and  yield load are determined. Next, a load up to 1.1 times as large as the yield load is  given by moving the piston 12. At this time, the internal pressure of the pipe 14 becomes 1.1 times as large as the yield load. The external load that has restrained the  maximum deformed part of the pipe 14 is removed at this point of time. Thereafter,  pipe expanding is completed by increasing the cylinder load up to 1.3-1.4 times as  large as the yield load. When the load is removed, the pipe becomes true circle.
