Title: Method for controlling drive of elliptic vibrating part feeder and device therefor
Inventor: AKAMA MASARU
IPC: B65G27/32
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of parts by connecting a phase regulating means to a first or second electromagnetic coil, and changing at least one of the inclination of the long axis of an elliptic vibration or the rotating direction of the elliptic vibration by the regulating of the phase regulating means so as to optimize the aligned supply of parts on a truck. SOLUTION: An AC power source is connected to a variable frequency power source by a switch, and an output voltage is supplied to an electromagnetic coil 15a through a PWM control circuit 54 and an amplifier 42 to impart a horizontally twisting vibrating force to a bowl 2. The output of a resonance point tracking control circuit 37 is supplied to a phase difference control circuit 56 through a wireway W4, and the phase difference control circuit 56 receives the output of a pickup 58 for detecting a vertical vibration, generates a voltage for causing a phase difference on the basis of the instruction from a phase difference instruction 57, and supplies it to a PMW control circuit 63.  The PMW control circuit 63 receives a vertical vibration command 60 and the output from a PI control circuit 62 based on this output, supplies a voltage for imparting a constant vibration to a vertical coil 12 after it is amplified by a power amplifier 64 to vertically vibrate the bowl 2.

Title: Amplifier circuit
Inventor: ETO TOSHIYUKI
IPC: H03F1/02
Filed: 1993-12-13
Abstract: PURPOSE:To attain wide band constitution in a low power consumption by constituting a differential pair of two transistors(TRs) and a constant current source, constituting a current mirror circuit of two other TRs so that a differential output from the differential pair is converted into a single end signal and providing another TR to be connected to the differential pair and to ground through its source. CONSTITUTION:A differential pair is constituted of TRs 1, 4 in a push-pull amplifier circuit and respective current sources, a current mirror is constituted of TRs 10, 11 and TRs 8, 12 are used as gate-grounded TRs. Differential signals impressed to input terminal 60, 61 are converted into a single end signal by a current mirror constituted of TRs 2, 3 and the single end signal is outputted to the drains of the TRs 3, 4. A TR 13 is driven by the single end signal to supply an intake current from a load connected to an output terminal 62. A discharge side to the load has two signal routes. One passes five TRs, i.e., 7 9 10 11 12, and conducts three times of phase inversion. The other passes three TRs, i.e., 7 8 12, and generates one phase inversion. The latter route has higher speed and acts as a feedforward pass for the former route to suppress phase rotation at high frequency.

Title: Hand shaking circuit
Inventor: YOSHIDA EIJI

Filed: 1987-12-09
Abstract: PURPOSE:To continue the processing of a microcomputer immediately after receiving a response from an external part and to transfer data at a high speed by providing a function to execute a releasing with a response signal to be able to hold an action state by a signal from the external part of the microcomputer. CONSTITUTION:A requesting signal 3 to aim at reading/writing data for an external circuit or the title device is made effective with an address decoder 2 and a logic circuit 7. While the signal 3 passes through a logic circuits 8 and 9, turns into a hold signal 5, and stops the action of a microcomputer 1, the signal 3 starts the clock of a counter 6.

Title: Protective circuit for magnetic disk device
Inventor: KANEKO HIROYUKI
IPC: G11B20/10
Filed: 1990-11-19
Abstract: PURPOSE:To prevent data destruction and to enhance reliability by prohibiting the writing of data to a magnetic disk device by a synchronizing circuit and a writing inhibition circuit when a service interrupted state arises instantaneously and announcing the generation of the service interrupted state by a state holding circuit. CONSTITUTION:The inputted signal for preliminary announcement of the breaking of the power source output attains a lower level when an instantaneous stop state arises. The synchronizing circuit 1, then, outputs a signal P1 in synchronization with a sector pulse and DF/F 7 and outputs a signal P2 to the writing inhibition circuit 3 in synchronization by a DF/F 9. The signal w of the writing inhibition circuit 3 attains a high level even when a data writing command signal is inputted as the signal P2 outputted from the synchronizing circuit 1 is the low level. The writing of the data to the magnetic disk of the magnetic disk device is prohibited by the rise of the signal w to the high level. The state holding circuit 5 maintains the state of the low level of the PPF when the PPF is inputted in the state of the low level. The state of the low level of the PPF is outputted to a buffer 1. The data destruction is prevented in this way and the reliability is improved.

Filed: 1987-12-10
Abstract: PURPOSE:To prevent the occurrence of trouble by giving the function detecting the abnormality of a system to start up sequence, and discontinuing transfer to power generating operation when the system is abnormal. CONSTITUTION:Starting voltage 23E detected with a cell starting voltage detector 23 is sent to a judgment circuit 34 which controls voltage comparison timing with an output signal 31E and compared with the reference voltage. If a fuel cell system is abnormal, the cell starting voltage is less than the reference voltage. The judgment circuit 34 detects this abnormality in an abnormal detecting step and outputs an abnormal signal 34E. A sequence controller 31 instructs a driving circuit 32 to stop fuel supply valve driving voltage 10E and to output an abnormal informing signal 35E. The driving voltage 10E drops zero and a fuel supply valve 10 is closed to stop fuel supply to a fuel chamber 2, and at the same time an annunciator 35 notifies the occurrence of trouble. The trouble can be detected early.
