Title: Filler metal for diffusion bonding
Inventor: NAKABASHI MASAKO
IPC: B23K35/30
Filed: 1983-09-26
Abstract: PURPOSE:To provide a filler metal for diffusion bonding capable of being used in a foil shape and rich in homogeneity and ductility, obtained by properly compounding a specific amount of Cr, Ni, B, Si, C, Mo and Fe. CONSTITUTION:A filler metal consists of, on an atom basis, 16-28% Cr, 6- 22% Ni, 5-22% B, 0-12% Si, 0-17% C, 0-2% Mo and the remainder of Fe and inevitable impurities. In this composition, the total content of B and Si or Si and C is pref. adjusted to 17-22%. This filler metal is especially useful in the liquid phase diffusion bonding of austenite type stainless steel. Because the NI-content of this filler metal is specified, a bonded part is held to an austenite phase equal to a matrix material. Because Fe is a main component, a phase rich in Ni is not generated in the bonded part.

Title: Manufacture of needle valve
Inventor: KONKI MASAAKI
IPC: B29L31/26
Filed: 1986-07-29
Abstract: PURPOSE:To make it possible to mount a fluororubber valve body to high heat-resistance engineering plastic and consequently to facilitate the manufacture, to realize the favorable accuracy and to reduce the cost of a needle valve by a method wherein inorganic fibers are mixed in the high heat-resistance engineering plastic, which is inferior in adhesion property, so as to expose the inorganic fibers only at a valve body mounting portion by making the molding temperatures at a shaft portion, a valve portion and the valve body mounting portion different from one another. CONSTITUTION:To high heat-resistance engineering plastic, 5-150pts.wt. of inorganic fibers are added with respect to 100pts.wt. of resin content. The inorganic fibers are exposed at a valve body mounting portion by molding a socket 2 under the condition that the mold temperature of the valve body mounting portion is made lower by at least 10 deg.C than that of a shaft portion 22. After that, adhesive having functional group is coated to the valve body mounting portion, onto which fluororubber is applied under high temperature and high pressure so as to form a valve body 3 portion. Because the inorganic fibers exposed at the valve body portion and the fluororubber are bonded together with adhesive, the bonding of the socket 2 and the valve body 3 with adhesive becomes possible. As a result, the conventional formation of a neck portion or a truncated cylindrical body at the valve body mounting portion becomes unnecessary and the simple and precise manufacture of a needle valve 1 becomes possible.

Title: Measurement of partial discharge of gas insulation device
Inventor: TAKAHASHI SHIGERU
IPC: G01R31/00
Filed: 1989-07-11
Abstract: PURPOSE:To detect with high sensitivity a partial discharge generated in a gas insulation device by connecting a measuring device directly to the end part of an insulated metal container. CONSTITUTION:If a metal powder 10 is included in the metal container 1, this powder is affected by an electric force to start the motion and a current pulse with extremely high frequency is generated at the same time. This current pulse is made to travel inside of the container 1 while repeating complicated reflections on the inside wall of container 1 or the surface of a high voltage conductor 2, etc., to reach the end part 3. At this time, a pulsative voltage caused by the partial discharge is generated at the end part 3 since an insulating plate 4 is interposed between the end part 3 and the container 1. This voltage is detected by a sensor 6 and introduced to a measuring instrument 9 through a measuring cable 8. Then, a specified display and recording are carried out here, thereby the partial discharge generated in the container 1 can be measured. Thus, the partial discharge generated in the gas insulation device is measured by making use of the end part 3 which is insulated from other metal containers; therefore, the pulse with high frequency generated according to a reflection phenomenon at the end part 3 of partial discharge pulse can be obtained.
