Title: Snow-melting member for overhead transmission line
Inventor: SHINOZAKI TOSHIYA
IPC: H02G7/16
Filed: 1988-10-07
Abstract: PURPOSE:To make it possible to ensure a large heat release value even in low magnetic field by using dispersed soft magnetic particles in a matrix consisting of good conductive metal. CONSTITUTION:As a snow-melting member 2 available when wound spirally around a transmission line main body 1, the following is prepared: using Al as good conductive metal into whose matrix grains of 50mum each in a particle size composed of 20wt.% of CuO, 30wt.% of ZrO and 50wt.% of Fe2O3 are dispersed. The compound ratio of soft magnetic particles is to be 82% in volume ratio. Even if very frangible soft magnetic particles are used, the particles are so dispersed in the metal of good conductivity that they can be rich in tenacity and flexibility as a whole. The use of a frangible material is thereby allowed and a sufficient heat release value can be ensured under the low magnetic field.

Title: Semiconductor substrate
Inventor: TACHIKAWA MASAMI
IPC: H01L21/36
Filed: 1986-10-27
Abstract: PURPOSE:To obtain a hetero junction type semiconductor substrate having no warpage at room temprature by providing, on a single crystal substrte, an intermediate layer which has grown as the single crystal with the same crystal orientation as that of single crystal substrate. CONSTITUTION:A first single crystal layer 2 consisting of GaPxAs1-x is formed on a Si single crystal substrate 1 and a second single crystal layer consisting of GaAs is then formed thereon. Here, change in volume of GaAs layer and Si substrate 1 due to thermal expanssion by temperature change from growth temperature up to room temprature (thermal expansion coefficient of layer 3 is larger than that of substrate 1), namely lattice mismatching is 0.22%. Moreover, a lattice constant of layer 2 is larger than that of layer 3 and the GaPxAs1-x mixed crystal having the lattice constant in which the lattice mismatching becomes 0.22% at growth temperature is used as the layer 2. In this crystal growth, the substrate warps toward a layer 3 due to the distortion genenated by the layer 3. This warpage is reversed from the recessed-warpage at room temperature and the projecting-warpage of substrate is cancelled at room temperature. Thereby, the single crystal layer 3' and Si substrate 1' having no warpage and lattice mismatching can be obtained.

Filed: 1986-10-27
Abstract: PURPOSE:To restrain the generation of vibration by providing such an arrangement that when the operation of a dash pot limiting the closing speed of a throttle valve is detected, the direct coupling between the output shaft of an engine and a speed change mechanism is released. CONSTITUTION:When a dash pot arm 57 makes contact with a dash pot spool 61 in association with the closing of the throttle valve 54, such contact is electrically detected and is delivered from a wire 64 so as to turn on a dash pot switch 45. With this arrangement a solenoid valve 40 is turned on through a relay 44, and therefore, a lock-up clutch 15 is operated by means of a lock-up control valve 30 so as to release the direct coupling between the output shaft 5 of an engine and an automatic transmission 1. Thus it is possible to release the lock-up clutch with no delay in timing even though a dash pot is provided, and thereby it is possible to restrain the generation of vibration.

Filed: 1990-09-27
Abstract: PURPOSE:To reduce energy consumption by writing stop information from a system to a control register and stopping oscillation by a gate circuit synchronously with a memory cycle. CONSTITUTION:When the stop information is written, a control circuit 13 generates a stop signal synchronously with the memory cycle so as to stop the oscillating operation through an AND gate 14 since a memory 3 is accessed asynchronously with the operation cycle of the system according to a clock generated by an oscillation circuit 2. In order to start the oscillation again, it is necessary to write start information from the system to a control register 12, and the stop signal is canceled by the control circuit 13, to which the start information is written, so as to start the oscillation again. Thus, since the oscillating operation of the oscillation again. Thus, since the oscillating operation of the oscillation circuit is selectively stopped under the control of the system, the energy consumption can be more reduced.
