Title: Enclosed switchboard
Inventor: NOGUCHI HIROHISA
IPC: H02B1/28
Filed: 1990-02-20
Abstract: PURPOSE:To shut a ventilating opening and open a bursting opening simultaneously with simple structure and a smaller number of required parts, by moving a shutting plate with the function of high-pressure gas produced upon occurrence of a short-circuit accident. CONSTITUTION:A ventilating opening 13a and a bursting opening 13b for the time of the occurrence of a short-circuit fault are provided at the ceiling section of a box-type enclosed package 13 containing a switchboard 1, and the bursting opening 13b is shut by the cut and raised section 15a of a shutting board 15 tilted to the inside of the ceiling section and jointed with a hinge. In time of normal operation, the ventilating opening 13a can change the inside air of the package 13 with the outside air freely through a hole 15b by the formation of the cut and raised section 15a of the shutting plate 15, as shown by a dotted- line arrow. In time of the occurrence of a short-circuit fault, the ventilating opening 13a is shut as the shutting plate 15 is pressed, tilted, and moved with the function of high-pressure gas produced by the fault, as shown by a solid-line arrow. As this enables a common shutting plate 15 to shut the ventilating opening and open a bursting opening simultaneously, the number of required parts can be reduced and simple structure can be obtained.

Title: Manufacture of torque sensor
Inventor: IKEDA MITSUAKI
IPC: C23C14/14
Filed: 1991-02-07
Abstract: PURPOSE:To enhance output while suppressing fluctuation by matching the direction of surface finish work of a rotary shaft to be applied with a magnetostrictive film with the longitudinal direction of the magnetostrictive film. CONSTITUTION:A rotary shaft 1 is fixed to a cylindrical grinding machine and then the rotary shaft 1 is rotated in the direction of an arrow A while simultaneously a grinding wheel 2 is fed axially (in the direction of an arrow B) thus grinding the surface of the rotary shaft 1 over a width L required for formation of magnetostrictive film 3. Consequently, helical machining is carried out and grinding threads are made in the direction (shown by an arrow C) inclining by 45 deg. against the axial direction of the rotary shaft 1. Magnetostrictive stripe films 3, exhibiting anisotropy in the direction of arrow D which is identical to the direction of arrow C, are then formed at the part of width L through sputtering, wet plating, or vacuum deposition. A detection coil 4 is then disposed oppositely to the magnetostrictive film 3 thus constituting a torque sensor. Anisotropy of the magnetostrictive film 3 is not disturbed by any machining flaw left on the rotary shaft 1 and stabilized torque output characteristics are obtained.
