Abstract: PURPOSE:To accurately adjust a light emitting point by setting a cut-off voltage by actuating a cut-off setting signal generation means by a control signal supplied from a cut-off voltage decision means, converting a light-emission amount into a voltage to display the result in digits. CONSTITUTION:A cut-off voltage inputted from an input terminal 22 is subjected to an insulated amplifier 25, and level-converted by a gain adjusting amplifier 26. Thereafter, the cut-off voltage is converted to a digital amount by an A/D conversion counter control part 28, and the input amount is displayed in an displayer part 27. This cut-off voltage is made come in a value determined by a television circuit, and the cut-off setting signal generation part 18 functions to achieve this purpose. That, decision control signals from a cut-off meter part 17 are supplied to an updown counter 38 through a line 24; in case a cut-off voltage impressed to the terminal 22 is lower than an upper limit and a lower limit set by the decision setting part 31, a decision control signal come to be an 'LO' signal which so functions that the output of the updown counter 38 descends and hence the level of a video signal also lowered.

Abstract: PURPOSE:To enable supply of grain to the ensuing process through the operation and stopping of a suction blower by connecting a grain storage part, a supply tank and a suction blower by means of a suction pipe, and providing a flap which opens under gravitation at the port of the tank bottom. CONSTITUTION:A flap 38 which opens under gravitation is fitted pivotably to a shaft 39 at the lower port 37 of a supply tank 11 in a slightly slackened manner. When a suction blower 14 is rotated, suction is made by means of a suction pipe reaching the vicinity of the bottom part of a grain storage part through a suction pipe 13 and a suction pipe 12, and the generated wind closes the flap 38 at the lower port 37 of the supply tank 11 against gravitation and the grain within the grain storage part is supplied into the supply tank 11 through the suction pipe 12. When the suction blower 14 is stopped, the flap 38 opens under gravitation, allowing the process to proceed to the ensuing step, e.g. allowing the rice to be supplied to a rice pearling mill 10 for pearling. In this case, in the beginning of the pearling process, the rice is half-pearled, and it is returned to the grain storage part by changing over a changeover valve, then taken out of the changeover flow passage by changing over a changeover valve.

Inventor: OKUMURA TAKESHI
IPC: H01R39/39
Filed: 1985-11-28
Abstract: PURPOSE:To absorb the vibration generated at the brush by applying the soft photoresistant resin to all over the brush arm portion except the sliding portion at the tip. CONSTITUTION:As for the brush for motor, a brush arm 1 is installed to the brush base 2, of which the tip of the brush arm 1 is divided into the forked segments and which has a terminal portion 3. Soft photoresistant resin 15 is applied to all over the area except the sliding portion at the tip of the brush arm 1 of this brush (where it contacts the commutator). As the photoresistant resin 15 is softer than the rubber, etc., each segment 14 can rockingly be moved independently even if the resin 15 is coated and the advantage the forked brush has cannot be lost. Furthermore, by absorbing the vibration by elastic force, the sliding of the brush to the commutator is smoothed and the rectifying characteristic stabilized. In addition, the coating work is simple.

Title: Detection of dissolution process in arc furnace for manufacturing steel
Inventor: AO NORIO
IPC: H05B7/148
Filed: 1988-10-25
Abstract: PURPOSE:To rationalize power charge and improve unit requirement of an electrode and refractories by disposing light sensers directed toward the inside of a furnace in a furnace cover at a proper interval, and detecting radiated light from molten pool by means of the light sensers. CONSTITUTION:Molten pool 2 changed from a scrap is stored down, and radiated light is produced from the molten pool 2 as parallel light beams to a furnace cover 5 at the top. Light sensers 7 are provided in the furnace cover 5 at a proper interval, and if an undissolved scrap is not existing over the molten pool 2, the radiated light reaches the light sensers to be detected by the sensers 7. In the meantime, if an undissolved scrap 6 exists stretched like a rack from a furnace shell, the scrap 6 breaks the radiated light to prohibit it from reaching the light sensers 7. By seeing distribution of detection of the radiated light by the light sensers 7, therefore, dissolution condition can be known. Waste consumption of power can thus be prevented, and unit requirement of the power, electrode and refractories can be improved.
