Title: Method for forming thermal boundary gasket and thermal joint
Inventor: FUIRITSUPU UIRIAMU ETSUKERUSU
IPC: F25D19/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a thermal boundary gasket and a thermal joint which can give necessary thermal conductance at a boundary joint. SOLUTION: An indium gasket 80 is provided with multiple openings 84 which are filled with indium which becomes deformed during compression between a low temperature cooler and a low temperature cooler boundary sleeve of a superconducting magnet system. Forming opening 84 in the gasket 80 has the effect of reducing mechanical boundary pressure under which the indium yields. The indium flows under a mechanical boundary pressure which does not exceed the required structural strength of the low temperature cooler. The indium flows into spaces formed by the opening 84 and gives a necessary thermal conductance between the low temperature cooler and the boundary. As a result, a relatively small temperature difference is obtained between the boundary sleeve and the low temperature cooler during the cooling of the superconducting magnet.

Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To stipulate the depth of a magnetic gap by polishing a sliding surface together a resistance detecting element which is arranged in a surface vertical to the sliding surface and which detects the volume change of it with an electric resistance change while cooling them and detecting the stock removal of it while measuring resistance changes when a magnetic gap is made a prescribed depth while polishing the sliding surface of a magnetic recording medium. SOLUTION: The magnetic head element and the resistance detecting element embedded in a thin film head 3 are exposed on a medium sliding surface S by cylindrically polishing a head chip 1 with a clindrical polishing stone while revolving it in the direction of the arrow C or rocking it in the direction of the arrow D. Next, the sliding surface S of the medium and the resistance detecting element are simultaneously ground in a grinding treatment for making the sliding surface S a mirror surface and making the magnetic gap a prescribed depth. When the polishing is performed while making a constant current flow through the resistance detecting element, the resistance of the element is changed by a volume change due to the grinding of the resistance detecting element and, thus, a voltage is changed.  Consequently, the stock removal of the resistance detecting element is known from the change in voltages and the correct depth of the magnetic gap is calculated.
