Title: Temperature measuring apparatus for integrated circuit element
Inventor: UMEZAWA KAZUHIKO
IPC: H02H7/20
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a highly reliable and simple temperature measuring element by a constitution wherein the temperature of an integrated circuit element is measured based on the temperature dependency of the resistance of a resistor wiring in the element. CONSTITUTION:A resistor wiring 3 on an integrated circuit element 1 and three resistors 5 form a bridge circuit. Since the resistors R1, R2 and R3 have fixed resistance, output from a galvanometer 7 varies according to the resistance of the resistor wiring 3. In other words, since the resistance of the resistor wiring 3 varies depending on the temperature of the integrated circuit element 1, output from the galvanometer 7 varied depending on the temperature of the integrated circuit element 1. When the relationship between the temperature of the integrated circuit element 1 and the output from the galvanometer 7 is calibrated previously, temperature of the integrated circuit element 1 can be determined based on the output from the galvanometer 7. This constitution realizes a highly reliable and simple temperature measuring element.

Title: Rotary damper
Inventor: KASHIMA MITSUHIRO
IPC: F16F9/14
Filed: 1990-11-30
Abstract: PURPOSE:To secure such a damping torque characteristic that is more than that of a telescopic type damper by forming a clearance between the inner circumference of a casing and the outer circumference of a side plate, and molding this casing with deformable wall thickness, in a rotary damper which is interposed between a body and an axle of a vehicle. CONSTITUTION:Each of separator blocks 7A, 7B is attached tight to the inner part of a casing 2, and each of oil chambers A, B is partitioned off in space with a vane body part 5. For example, at time of operation at an expansion side where an upper arm 22 rotates its tip downward, the oil chamber A is contracted by relative rotation of a vane 4 of the casing 2, while the oil chamber B is expanded the other way, and a part of working oil in the oil chamber A flows into the oil chamber B through a rocking clearance (a) between the vane body part 5 and the casing 2, a peripheral clearance (b) between two side plates 6A and 6B, and other clearances (c) and (d), generating the expansion side damping force with flow resistance. In addition, up pressure in the oil chamber A acts on a relief valve 11 at a port 8A, pushing this relief valve 11 open at more than the specified value, and the working oil flows into the oil chamber B from the oil chamber A. As for a pressure receiving area, it is small in the port 8A and the expansion side damping force grows larger. In this connection, wall thickness in the casing 2 is made deformable with hydraulic pressure.
