Title: Optical signal transmitter and receiver
Inventor: YUGAWA TOMIO
IPC: H04B10/07
Filed: 1981-10-29
Abstract: PURPOSE:To always assure the correct reception of an optical signal regardless of a change of the transmission loss, by deciding the threshold level based on the level of a signal obtained from a steady electric signal like a clock signal, etc. and receiving data signals. CONSTITUTION:A steady electric signal 3 like a clock signal, etc. is synthesized with an unsteady electric signal 4 at the side of an optical transmitter by conversion between two different wavelengths lambda1 and lambda2, and then transmitted. The receiver side separates the synthetic optical signal and decides the threshold level on the basis of the level of the signal obtained from the signal 3 and then receives the unsteady optical signal lambda2 showing a data based on the threshold level. As a result, the correct reception is always possible for optical signals.

Title: Brushless motor
Inventor: FUKUOKA TOSHIAKI
IPC: H02P6/12
Filed: 1990-06-29
Abstract: PURPOSE:To suppress sharp change of the current of an output circuit by restricting a current flowing to the output circuit with specified first slope in phase switching and at the same time controlling the current of a switching circuit with specified second slope. CONSTITUTION:The collector of a transistor 39 composing a current mirror circuit is connected to the common emitter of the three differential amplification circuits of a switching circuit 5. With that structure, the collector current of the transistor 39 composing the current mirror circuit increases and flows into a constant-current source 32 with increase in the output current of a transistor 33 which receives the output signal of a threshold circuit 4. As a result, the current passed through the switching circuit 5 is restricted and decreased. Therefore, current slope in phase switching is arbitrarily determined by selecting an appropriate ratio of resistance 37 to resistance 38 and determining the current ratio of the current mirror circuit. As a result, reluctance torque does not need to be increased and a switching pulse can be removed.

Filed: 1982-10-01
Abstract: PURPOSE:To reduce the power consumption of a drive circuit, by using a push- pull circuit comprising switching elements for driving a line cathode generating electron beam. CONSTITUTION:When vertical drive pulses [A-P] are applied to a base of transistors (TRs) 44, 45 of a push-pull circuit, TRs 45A-45P are cut off at a low level of the pulses, i.e., at heating period, TVs 44A-44P are conductive, and they are operated inversely during the period when electron beam is to be generated, and diodes 43A-43P are cut off. No current from a heat power supply flows to line cathodes 2A-2P to generate the electron beam, they are at a low potential and a prescribed electron beam is emitted independently of the resistance value of each line cathode and a prescribed electron beam is irradiated. The current flowing to the TRs 45A-45P at the period generating the electron beam is a minute current only attended with the irradiation of electron beam from each line cathode and almost no current consumption is produced. Further, the current flowing to the TRs 44A-44P during the heating period is only the heating current flowing to the linear cathode and the TRs 44A-44P can be of small capacity.
