Title: Circuit-breaker with wiring for electric leakage alarm function
Inventor: AKIYAMA TOSHIHIRO
IPC: H01H83/02
Filed: 1990-01-12
Abstract: PURPOSE:To achieve miniaturization, save installation works, and improve monitoring level by containing a zero phase current transformer and electric leakage relay in a shutting case of a circuit-breaker and at the same time installing a terminal for electric leakage current monitoring. CONSTITUTION:When electric leakage happens, the electric leakage current is detected by a zero phase current transformer 9 and amplified by an amplifying part 11 to drive an electric leakage relay 10 to ring an alarm. At the same time an electric leakage displaying part 13 starts to work. Since the alarm is electrically lutched in the circuit, it is kept till a re-set button 14 is pushed or an electric power source of a main circuit is rid off. Like this, if the current transformer 9 and the relay 10 are put in the shutting case, only installation of a circuit-breaker 4 on a board is necessary. If necessary, electric leakage current is simply measured by connecting a measuring apparatus with the terminal for monitoring electric leakage current.

Title: Cooling method for hot steel plate with different thickness
Inventor: YAMAMOTO MASANAO
IPC: B21B15/00
Filed: 1986-01-14
Abstract: PURPOSE:To uniformly cool steel plate parts in the vicinity of a thickness changing line by obtaining an optimum cooling condition based on a temp. at plural dividing points in the longitudinal direction of the plate and controlling a plate passing speed in accordance with a thickness of the plate. CONSTITUTION:A radiation thermometer 12 measures a temp. at plural dividing points in the longitudinal direction of a hot steel plate S prior to insertion of the plate S into a cooler 3. An optimum cooling condition at each dividing point is calculated a controlling calculator 4 based on the measured value. When the plate is cooled with its thicker part at the head, a passing speed is lowered to supplement a shortage of a cooling time for the thicker part prior to insertion of the thickness changing line into the cooler 3. The passing speed is accelerated up to the speed for a thinner part passing at the instant when the thickness changing line enters the cooler 3. In the case of the thinner part at the head, the speed is first accelerated and then decelerated. In this method, both the thicker and thinner parts around the thickness changing line are uniformly cooled to the target temp.

Title: Polalization of ultrasonic motor element
Inventor: TAMURA MITSUO
IPC: H01L41/257
Filed: 1987-01-12
Abstract: PURPOSE:To prevent the generation of spark discharge and fine cracks, by applying alternately a half-wave rectification voltage rectified via a rectifier to series-connected positive and negative polarization electrodes, in the case where a voltage is applied to the positive direction and the negative direction of a polarizion power source using an alternating current. CONSTITUTION:One side of the ring of a piezoelectric ceramics 1 is a common electrode 4, and the other side is composed of an electrode groups 2 and 3 polarized by a positive and a negative voltages. Each electrode is radially arranged around a ring center and separated with constant angle intervals. Neighbouring electrodes are so constituted that each of them has a polarization of different direction from each other. As to a power source for polarization, the half-wave rectification voltage of an alternating current 8 by, for example, rectifier diodes 91 and 92 is used, and the voltage is alternately applied to the electrode groups 2 and G of positive and negative directions. Thereby, potential difference between the electrodes is maximized under the same condition as the case where the voltage is applied only in one direction, and the polarization can be simultaneously progressed in both directions. Therefore, the equiblium of polarization in the positive and the negative directions is sufficiently maintained, and a high reliable element for a motor wherein spark discharge and cracks do not generate between the electrodes can be obtained.
