Inventor: OKAMURA CHIAKI
IPC: H02H11/00
Filed: 1995-03-15
Abstract: PURPOSE: To prevent the deterioration of a circuit by preventing the repetition of turning on/off of switches on a power supply under an overcurrent state. CONSTITUTION: This is an overcurrent protection circuit which can interrupt an output current by turning off switches 23 and 25 provided in a power supply when an overcurrent state occurs in operation power to be supplied to a load connected to a power supply equipment 10. This equipment comprises overcurrent detection means 22, 28 and 29 which detect an overcurrent state and generate overcurrent detection signals, holding circuits 32 and 33 which receive these detection signals, output off-command signals and retain this output state until an off-release command is given and forced interrupting means 34 which forcibly maintain off-state for the switches 23 and 25 during the time when the off-signal is being output.

Title: Automatic cleaning device of roller type disposer
Inventor: ONO TOKIO
IPC: B65G45/14
Filed: 1982-04-02
Abstract: PURPOSE:To scrape off deposits from the respective roller surfaces by a structure wherein a traversing frame to traverse rightward and leftward is provided at the lower part of the roller type disposer and scrapers mounted on the frame are brought into contact with the undersides of the rollers. CONSTITUTION:When a chain 11 is turned in a certain fixed direction by means of a driving device 13, a front and a rear screw rods 9 are also turned in a certain fixed direction and the traversing frame 16 is shifted from left to right facing to the disposer by means of the engagement of the rods 9 with female screws 17. When the frame 16 reaches the right end of the rods 9, a detector is put into actuation so as to reverse the rotation of the rods 9 by reversing the rotation of the driving device 13 and to shift the reversing frame 16 leftward. When the frame 16 reaches the left end of the rods 9, a detector provided at the left side of the disposer is put into actuation so as to put the driving device 15 in its former normal rotation in order to start to shift the traversing frame 16 rightward again. Owing to the structure as mentioned above, the scrapers 20 are shifted in the direction of the axis of the rollers 2 while being brought into contact with the underside surfaces of the rollers 2 and at the same time the rollers 2 are in rotation. Accordingly, the deposits are scraped off by the scrapers 20 from the peripheral surfaces of the rollers 2.

Title: Manufacture of iii-v semiconductor device
Inventor: KUZUHARA MASAAKI
IPC: H01L21/76
Filed: 1986-03-13
Abstract: PURPOSE:To enable the attainment of the insulative isolation between field effect transistors without impairing the surface smoothness of a semiconductor substrate, by a method wherein the surface of a P-type III-V semiconductor layer is covered with silicon oxynitride film except for a region for forming the field effect transistors having an N-channel and a P-channel, and infrared short-time annealing is applied thereto. CONSTITUTION:When a deep electron trap is introduced from outside into a P-type conductor layer 2, the level of electrons caught so far by the electron trap lowers to a shallow acceptor level, and therefore the emission of free holes into a valence band is hindered. When a shallow acceptor level concentration is denoted by N, and a deep electron trap concentration by NDD, a free hole concentration (p) is expressed by p=NA-NDD. If NDD is introduced in a more quantity than NA, accordingly, (p) turns less than 0, and a semiconductor 1 turns to be of high resistance. When infrared short-time annealing is applied to a P-type III-V semiconductor whose surface is covered with a silicon oxynitride film 8, the deep electron trap is formed, and consequently high resistance is attained. By this method, the insulative isolation between field effect transistors can be attained.

Filed: 1979-05-09
Abstract: PURPOSE: To effectively perform the dissociation of emulsion by a small amount of steam, by selectively heating an emulsion layer in the separation of a by-product tar generated from a coke oven by means of a decanter.  
     CONSTITUTION: In the separation by sedimentation of a by-product tar generated from the coke oven 1 into which preheated coal or dried coal is charged by means of the decanter 8, the emulsion layer 13 in the decanter 8 is sucked up by the pump 17, and the emulsion is heated to 80W100°C by the heater 18 and again fed back to the emulsion layer 13, during which period the emulsion is separated into tar and water. Thus, the heat quantity used in the heater 18 is given to the emulsion alone and therefore the temperature of the emulsion layer 13 can be kept high by a small amount of heat quantity, preventing the expansion of the emulsion layer.

Title: Position control system for feed shaft
Inventor: NASHIKI MASAYUKI
IPC: B23Q15/00
Filed: 1988-03-10
Abstract: PURPOSE:To reduce the delaying time of a table action by always detecting the dead zone of a table action for a moving direction, at the time of activation, adding the dead zone of an activating direction to the rotation action command of a motor and controlling the rotation position of the motor in accordance with the command. CONSTITUTION:By using a difference DV between a motor rotation position and a table position while the dead zone occurs in one direction during the table action, etc., and a difference D between the motor rotation position and the table position while the dead zone exists in both front and rear directions, a difference DRL(=DV-D) in both is calculated and the dead zone of respective both directions when the difference D is calculated is obtained as the DRL. Consequently, when the calculation of the difference D is executed, for example, immediately before the table is activated, the dead zone in the activation direction can be obtained by calculation. A dead zone correcting quantity is added to the position command of the motor and the relative position relation is controlled. Thus, the shaft action activation time is shortened and the locus error at the time of the multi-shaft synchronization operation accompanying this can be reduced.
