Title: Level gauge and level thereof
Inventor: AOKI SEIJI
IPC: G01C9/22
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain a level gauge which enables horizontal standard to be conformed easily and speedily, is easy to use, and eliminates the need for replenishment with water, etc., on the spot. SOLUTION: This level gauge 10 is equipped with a pipe 11 which is made of a transparent vinyl chloride. The pipe 11 has both its ends linked to each other and is looped. The pipe 11 contains water 12 almost to a half and the remainder is an air region 13. In using, both the ends of the level gauge 10 are held by, for example, two workers and respective grip parts are attached to desired columns to be marked with horizontal standards. Then the water levels 14 and 15 in the pipe 11 balance at equal height. The water levels 14 and 15 are connected together in the air region 13 and do not contact the outside air, so that both the water levels 14 and 15 balance smoothly at the equal height. Here, the two workers only marks the columns with the horizontal standards. Therefore, the handling is facilitated, and operation is speedily done.

Title: Method and apparatus for detecting deterioration of electrolytic capacitor
Inventor: ADACHI KENJI
IPC: H01G13/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To detect deterioration of an electrolytic capacitor without removing it from a printed wiring board. SOLUTION: A case 11 is provided with an opening which is then fixed with a plate material of transparent or translucent resin to form an observation window 13. A capacitor element 103 is inserted from an opening in the bottom of the case 11 and encased therein. At the time of detecting deterioration, shade of a capacitor paper constituting the capacitor element 103 is observed through the observation window 13. When the electric characteristics of an electrolytic capacitor deteriorate due to evaporation of electrolyte, the capacitor paper is dried and light-colored. Extent of deterioration of the electrolytic capacitor is determined based on the extent of shade of the capacitor paper.

Title: Driver for motor and air conditioner
Inventor: TAKAKURA YUUYA
IPC: H02P27/06
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To protect a system, by operating a booster chopper circuit in a rated voltage range, when a motor is rotated under condition using the booster chopper circuit. SOLUTION: A motor controller 14 includes an inverter 10 with a conduction ratio of 100%. Even in a control range, in which the speed of the motor 11 is controlled by changing an input DC voltage Vd, the input DC voltage Vd of the inverter 10 is monitored on the bases of an DC voltage signal S4. When the load of the motor 11 increases and the input DC voltage Vd exceeds a given level, the conduction rate of the booster chopper circuit 3 is controlled and the input DC voltage Vd is reduced below a given level so as to lower the applied voltage to a given rated level. In addition, even if the input DC voltage Vd does not increase by increasing the specified revolutions of the motor 11 in the control range, or the input DC voltage Vd drops abruptly, the motor 11 and the booster chopper circuit 3 are stopped by regarding the booster chopper circuit 3 as being in a failure state.

Abstract: PURPOSE:To enable the positional accuracy between a block of a thermal head and two transfer systems to be retained easily by a method wherein the thermal head block and the transfer system of a recording paper and of an ink ribbon are incorporated in a common block of a device and the thermal head block is opened in a predetermined open position. CONSTITUTION:A head block 18 of a thermal head 2, a transfer system 3 for recording paper P and a transfer system 12 of an ink ribbon R, in a fixed positional relation to one another, are incorporated in a common block of a device, i.e. between both plates 20 serving as a retaining means. Therefore, the positional accuracy between the head block 18 and the two transfer systems 3 and 12 is retained easily by the two side plates 20 and an exact matching in position thereof can be maintained. Moreover, the head block 18 is rotatably movable in conjunction with the upward opening and closing of an upper lid 23. When the upper lid 23 is opened, the head block 18 can be brought in an open position F kept largely apart from the transfer system 4 of the recording paper P and the transfer system 12 of the ink ribbon R. Since the transfer system 3 is directly accessible when a cassette 17 is taken out, paper jamming can be corrected easily.

IPC: H01S5/00
Filed: 1983-10-06
Abstract: PURPOSE:To miniaturize, stabilize and integrate an optical bistable element by detecting diffracted beams from a semiconductor laser incorporating a higher Bragg diffraction grating, converting the diffracted beams into an electric output and feeding back the diffracted beams to the semiconductor laser.

Abstract: PURPOSE:To prevent the counter-flow of the water into a ship without sacrifice of the drainage function, by arranging a float valve in a drainage path and closing the drainage path by means of the float valve when the water has intruded from outside of the ship. CONSTITUTION:When a drainage path 7 is not intruded with the water, a float valve 9 is at the position shown by the dashed line and the drainage path is not closed thereby the water in the ship is exhausted through said path 7 to the outside. When the wave will attack or the water line under full load will vary and the drainage path 7 of the casing 8 is intruded with the water, the float valve 9 will float and move upward then contact tightly with a valve seat 10 as shown by the solid line, thereby the drainage path 7 is closed to prevent the counterflow of the water into the ship.
