Title: Rotational speed detector for dc motor
Inventor: SATO KOZO
IPC: H02K11/00
Filed: 1988-04-15
Abstract: PURPOSE:To standardize the design of an apparatus and to shorten the delivery date thereof by selecting a board obtained through forming generator patterns with different frequencies on a plurality of printed wiring boards and through laminating said plurality of printed wiring boards and by causing the thus obtained board to generate electricity in the manner of corresponding to a magnet of rotor. CONSTITUTION:Boards 14a-14d on which a plurality of different conductor patterns 17a-17d for frequency generators are printed are laminated to form a multilayer printed board 14. When power is applied from a driving circuit 16 to an armature coil 6, a rotor 7 starts rotation, the magnetic flux of a magnet 13 for frequency generators, attached to said rotor 7, moves while crossing with said pattern 17a, and a voltage proportional to the rotational speed of the rotor 7 is generated from the output terminal of said conductor pattern 17a. The speed is detected by selection of said voltage through a switch 18. Even if the magnetization pattern of the magnet 13 is different, one multilayer printed board for the same driving circuit 16 can cope with four types of motors. Thus, it is possible to standardize the design of an apparatus and to shorten the delivery date thereof.

Abstract: PURPOSE:To ensure the highly efficient maintenance and checking in a simple constitution, by connecting the main master station to the secondary master station and slave station via the 1st and 2nd up-circuits and then detecting the fault occurring to the up-circuits at the master stations to change-over the circuits. CONSTITUTION:The connection is secured among slave station 21, main master station 22 and secondary master station 23 via up-circuit 24 and down-circuit 25 each. The up-circuit possesses the 1st and 2nd circuits 241 and 242 and is then connected to the both master stations via circuit change-over switches 26 and 27. Slave station 21 is provided in plural numbers, and its transmitting circuit consists of modulator 31, hybrid transformer 32, level adjusters 33 and 34 plus circuit changeover switch 35 each. Adjusters 33 and 34 are controlled so that the transmission signal arriving levels to the both master stations may be equal to each other in accordance with the distances to the both master stations. And now if the fault occurs at point A of circuit 242 and in the state of connection of each switch as shown in the figure, this fault is detected at stations 23, 22 and 21 each. Then the changeover is given among switches 27, 26 and 35 to transmit the signal sent from the slave station to the direction of the dotted line in the figure. In such way, the reception with the steady receiving level is possible at each of the two stations.

Title: Chopper controller for electric railcar
Inventor: AWANO TOSHIAKI
IPC: B60L7/12
Filed: 1983-05-27
Abstract: PURPOSE:To improve the riding feeling of an electric railcar by connecting a function generator which has a transfer function characteristic of the primary delay in series with a pattern generator, thereby preventing the abrupt rise of a motor current. CONSTITUTION:A brake command signal IPO is converted by a pattern generator which has the primary delay transfer function into a pattern signal IPO', and further converted by a pattern generator 4 which has another primary delay transfer function into a current pattern IP. A comparison amplifier 2 outputs a deviation signal e0 between the current pattern IP and a motor current IM, and a conduction rate converter 3 outputs a conduction rate (gamma) of a chopper in response to the signal e0. In this manner, the impact when the motor current rises can be reduced.

IPC: G11B7/0045
Filed: 1990-04-10
Abstract: PURPOSE:To always record information under an optimum state without receiving the effect of temperature change or secular change by detecting a state that a pit is recorded based on the output of a signal reproducing means and controlling the light power of a light source when the information is recorded according to the recording state thereof. CONSTITUTION:After ordinary data is recorded, the data is verified. At this time, the state of a signal reproduced by the signal reproducing means 102 is detected by a recording state detection means 103. When it is judged that the reproduced signal is recorded by the light power whose value is lower than an optimum value, a command is given to a light source driving means 105 by a light output control means 104 according to the state so as to make the light power strong. Then, the light current of a semiconductor laser is increased. On the contrary, when it is recognized that the reproduced signal is recorded by the light power whose value is higher than the optimum value, a reversal action is executed. By such consecutive operations, the light power is controlled so as to make it always the optimum value.
