Title: Excitation controller of synchronous machine
Inventor: MURAKAMI HITOSHI
IPC: H02H3/26
Filed: 1993-12-22
Abstract: PURPOSE:To control field current so as to maintain safe operation of a synchronous motor under any condition. CONSTITUTION:An automatic voltage adjustment part is provided with a usage system and a standby system to set the terminal voltage of a synchronous machine to a specific voltage setting value. When the automatic voltage adjustment part of the usage system fails, the automatic voltage adjustment part of the standby system is selected and the operation of the synchronous machine continues. A comparison part 17 calculates the deviation signal between the control signal output by the automatic voltage adjustment part of the usage system and the control signal output by the automatic voltage adjustment part of the standby system. Then, an automatic following part 19 changes the voltage setting value of the automatic voltage adjustment part of the standby system so that a deviation signal reaches a specific value and supplies a field current to the field coil winding of the synchronous machine so that the synchronous machine can be operated safely based on the control signal matching the deviation signal of a specific value output by the automatic voltage adjustment part of the standby system when the automatic voltage adjustment part of the usage system fails.

Title: Playing device
Inventor: MATSUMOTO MITSUHIRO
IPC: G10H1/00
Filed: 1993-11-30
Abstract: PURPOSE:To provide a playing device in which one key playing is easily made. CONSTITUTION:In an SF3, data (ADR) stored in an address ADR indicated by a current value of a register ADR are stored in a register P. In an SF6, data (ADR), which are stored in the address ADR indicated by a current value of the register ADR that is incremented, are set in a time T. Whenever the timer T becomes '0', (every time a note length time corresponding to one note is lapsed) pitch data (P) corresponding to a next note are successively set to a register P and note length data (T) corresponding to the same note are successivley set to a timer T. Thus, automatic playing data of a selected music are successively read employing this flow and an automatic playing of the music progresses internally. When a one key SW is operated, a sound is instructed with the pitch specified by the pitch data stored in the P register.

Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmitter which causes no damage to human eyes, when an optical connector plug is detached from a receptacle in a state in which the transmitter is emitting light rays. SOLUTION: In a state in which light rays are emitted from a light emitting element 1, when an optical connector plug 10 is fitted into a receptacle 5, light rays emitted from the light emitting element 1 are reflected from the optical connector plug 10 and received by a photodetector 3. A receiving circuit 4 connected to the photodetector 3 controls an amplifier 2 so as to enhance its drive current, and required light in emission intensity is emitted from the light emitting element 1. When the optical connector plug 10 is detached from the receptacle 5, light rays emitted from the light emitting element 1 are not reflected from the optical connector plug 10 and no longer will not be received by the photodetector 3.  The receiving circuit 2 makes the drive current of the amplifier 2 lowered, so that the light emitting element 1 is reduced in emission intensity so as not to cause damages to human eyes.
