Title: Magnetic separator
Inventor: OISHI NAOKI
IPC: B03C1/032
Filed: 1991-03-12
Abstract: PURPOSE:To provide the magnetic separator which removes the rolling mill lubricant leading to the flaws and stains of cold rolled sheets, etc., and the iron powder included in an electrolytic cleaning liquid. CONSTITUTION:This device is constituted of an attachable and detachable magnetizing device 5 and amorphous alloy filter media 3. The rolling mill lubricant and electrolytic cleaning liquid, etc., admitted into the device by passing a piping 2 are subjected to the removal of the iron powder in the liquid by the magnetized media and are returned through the piping 6 into a tank. The iron powder removed by the cleaning deposits on these filter media degrades the filter performance and, therefore, the media are periodically washed and the iron powder is discharged to the outside of the system. The filter washing is executed by parting the magnetizing device 5 from the filter media 3, supplying back washing water to the media through a piping 7 and simultaneously blowing bubbles from a gas ejection pipe 9 provided in the media, by which the iron powder sticking to the media is stripped away and the filter performance is restored.

Title: Flash device
Inventor: TAKEMATSU YOSHIYUKI
IPC: H05B41/36
Filed: 1979-04-17
Abstract: PURPOSE:To assure correct quantity of light by so constituting the device that no resistance is connected between a diode and the 2nd electric discharge tube. CONSTITUTION:When an electric power source switch 2 is turned ON, high voltage is generated in the secondary coil 5c of a transformer 5, causing a neon tube 12 to light. When a synchronizing switch 14 is turned ON in this state, a trigger pulse is generated in the high voltage side of a trigger coil 18 and at the same time a trigger pulse is generated in a detecting coil 17 as well, by which a trigger pulse is generated in a trigger transformer 35, causing an electric discharge tube 36 to emit light simultaneously with an electric discharge tube 19. When in this way the discharge tubes 19 and 36 emit light and correct exposure is reached, the light emission is stopped by way of an exposure adjusting circuit 37, etc. Since the internal resistance values of the discharge tubes 36 and 19 are made nearly the same in order to make the flash time nearly the same in this way, there is no need for connecting resistance between a diode 7 and discharge tube 36 and this decreases losses owing to the resistance and enables correct exposure to be assured.

Title: Semiconductor laser with protecting circuit
Inventor: SAKAKI SHIGEO
IPC: H01S5/042
Filed: 1982-03-26
Abstract: PURPOSE:To protect a laser diode from breakdown at a low cost by a method wherein a junction type FET is connected in series with the laser diode, and two constant voltage diodes are connected in parallel therewith. CONSTITUTION:The junction type FET2 is connected in series via a drain electrode D on the side of the anode of the laser diode 1. The value of the saturation current of the FET2 is contrived to be equal to the value B of forward directional current which generate the maximum light-output A in the safety operational range of the laser diode 1, or to become lower. On the other hand, the two constant voltage diodes 3 and 4 are connected in parallel with the laser diode 1 and the FET2 as back-to-back. When positive and negative currents are impressed on terminals 5 and 6, the withstand voltage E of the diode 4 selects a voltage whereby breakdown is not generated in a state that the drain current of the FET2 is saturated.

Abstract: PURPOSE:To integrate the heat storage type floor heating with the heat storage type air conditioning systems by serially arranging the heat storage tank, indoor heat radiator and heat storage type heater mat in a loop which is connected to the heat source side heat exchanger through a circulating pump, and performing either the air conditioning or heat storage by combining the equipment as needed. CONSTITUTION:A heat storage tank 1 which stores energy at night for air conditioning, an indoor heat radiator 2 and a floor heating mat 3 having a heat storage board 11 are serially connected, which are connected to the heat source side heat exchanger 4 via a hot water pump 5 with a pipe 12. By this arrangement, the heat can be stored with a temperature distribution suitable for the operating temperature of the respective devices. When the room temperature reaches a predetermined level, the valve 7 is opened to bypass the hot water, and, when the floor heating mat 3 completes its heat storage, the valve 8 is opened likewise to bypass the hot water. In order to release into the room the heat which was stored in the storage tank 1 during the night, the valves 6 and 7 are closed and the valves 8 and 9 opened to circulate the hot water with the pump 5. As the floor heating is not needed in the summer, the valve 10 is held closed. Therefore, for the cooling operation, the line becomes the same as that for the air conditioning using standard brine.
