Title: Method of preventing flashover of dc machine
Inventor: KAWASHIMA YOSHINORI
IPC: H02P7/292
Filed: 1989-05-18
Abstract: PURPOSE:To prevent flashover of a DC motor by detecting the temperature of its brush and controlling the current flowing to the brush in accordance with the detected temperature. CONSTITUTION:When a DC motor 24 is operated, the speed of the motor 24 is controlled according to a speed command by a control circuit, and a thermometer 40 simultaneously detects the temperatures of brushes 12 and inputs the detection temperatures T to a brush temperature malfunction discriminator 38. The discriminator 38 compares all the input brush temperatures T with set temperatures alpha1-alpha4, selects current limiting values beta1-beta5 depending on the temperature T, and alters the limiting value of a current limiter 37. Thus, all the currents fed to the motor 24 are limited. In this manner, it suppresses the excess current flowing to the brush to prevent an overload, thereby preventing flashover.

Abstract: PURPOSE:To shorten time until tracking is turned to an optimum state by detecting a deviating direction immediately when a track on the magnetic tape of a magnetic head is deviated from the center line of the track recorded onto the magnetic tape in advance. CONSTITUTION:Discrimination circuits 10 and 11 respectively output signals 101 and 102 as the results of envelope detection to output signals from a preamplifier 4 and a delay circuit 9 and output discrimination signals 103 and 104 to decide whether the signal reaches a prescribed level or not. When scanning is executed while deviating the center of a magnetic head HA1 to the side of a track Bn-1 from the center line of a track An, a changeover switch 14 is turned to the state of connecting a 14a by detecting that time tS required for the scan of a logic circuit 12 shown by the difference of starting time for the discrimination signals 103 and 104 obtains difference more than the allowable error of prescribed time, and the signal 102 at a level in proportion to the envelope of the reproducing signal of an HB'3 from the discrimination circuit 11 is guided to a driving circuit 15. Thus, the speed of traveling the magnetic tape is increased and the track at the center of the HA1 is controlled to correctly trace the center line of the track An.

Filed: 1990-05-17
Abstract: PURPOSE:To efficiently execute the stirring and the carrying of toner in the inside of a toner container by forming the supporting part of a second stirring member with respect to a first stirring member with the aid of giving play. CONSTITUTION:The supporting part which is freely rotated consists of the shaft part 6a of the first stirring member 6 and the hole part 7a of the second stirring member 7.

Title: Tape recorder
Inventor: YOSHIDA MASASHI
IPC: G11B15/10
Filed: 1977-10-21
Abstract: PURPOSE: To make possible automatic resetting of play plate at the time of service interruption by stopping the play plate, which has been put in a playback state by way of the arm, play gear, etc. cooperating with a temporarily energized solenoid, by means of another solenoid.  
     CONSTITUTION: A temporarily energized solenoid 27 turns an arm 27, and a play gear 22 is turned by means of a pin 23 which is pressed by the arm 26 turning cooperatively with said arm. This causes a gear 22 which has intermittently toothed part and a flywheel gear to be intermeshed, thereby turning a play arm 33. Then the pinch roller of the play plate 6 moved via pin 8 makes pressure-contact to a capstan, letting the head make contact to a tape and setting a play state. Next, when a solenoid 13 is energized, a lock plate 10 is stopped by a stopping groove 10A and pin 7, and the play plate 6 is thereby locked. This lock is released when the solenoid 13 is de-energized. The play plate 6 is then reset by the elastic force of a spring 16, thus even at the service interruption, the inconvenience owing to the pressure-contact, etc. of the pinch roller to the capstan does not occur

Title: Wavelength multiplex star type network
Inventor: IWASAKI KAZUNORI
IPC: H04B10/272
Filed: 1980-09-10
Abstract: PURPOSE:To realize a network with high efficiency, by multiplexing an optical data with wavelength. CONSTITUTION:An optical data is inputted via a transmission line 3R. This optical data is branched on wavelength at a brancher 6 consisting of prism and the like and given to photoreceivers 7a-7n. The 1st photoreceiver 7a is to receive the light having the wavelength assigned in advance specific to the station. The station name and command for the communicated address are interpreted from the output of the receiver 7a at a logical section 8. The transmission line is minitored with the output data of the remaining photoreceivers 7b-7n. After the absence of communication is condirmed with the wavelength assigned to a desired communication station, the transmission of optical data is made. Thus, even if the network is tied in star shape, the collision of data can be avoided.

Abstract: PROBLEM TO BE SOLVED: To stop filling of grain accurately by detecting the load current value of a drive motor in a board for scattering grains through rotary action, comparing the detected load current value with a threshold level corresponding to the filling state and determining the filling state and then controlling operation/ stop of the drive motor. SOLUTION: When a filling button is turned on, a drive motor 10 is driven to turn a scattering board 13. Grains in a hopper are transferred through an elevator 6 and a lateral carrying machine 7 onto the scattering board 13 thence scattered around thus filling in a storing section 2. When the storing section 22 is filled with grains, the current (load current) being fed to the drive motor 10 is detected through a load current section attached to a motor drive circuit. The detected load current value is compared with a threshold level corresponding to a prestored filling state and the drive motor 10 is stopped when the threshold level is reached.
