IPC: H02H7/18
Filed: 1988-01-26
Abstract: PURPOSE:To prevent over-discharge of a battery, by interrupting a load from being connected to a power source circuit if the battery voltage is lower than a set level upon stoppage of operation of a rectifier. CONSTITUTION:In a circuit having a load 8 connected with a power source circuit comprising a battery 1 and a rectifier 10 and supplied with voltage from the power source circuit, operation of the rectifier 10 is stopped due to fault such as power interruption or malfunction. A voltage monitor circuit 2 in a battery control section 9 monitors voltage of the battery 1 and provides an operation signal 3 upon droppage of the battery 1 voltage below a set level to a relay 4. Consequently, the relay 4 functions to close a contact 5 so as to operate an electromagnetic interrupter 6 thus opening a contact 7. As a result, voltage supply to the load 8 is stopped thus preventing over-discharge of the battery 1.

Title: Frequency synthesizer
Inventor: KUMAGAI KAZUHIKO
IPC: H03L7/081
Filed: 1983-01-31
Abstract: PURPOSE:To generate an optional frequency which is stable regardless of the purity of a phase comparison signal by controlling a voltage-controlled oscillation circuit by the output voltage of a D-A converter. CONSTITUTION:A phase comparison part 2 makes a comparison to detect whether the phase of a feedback signal from a frequency-dividing circuit 5 leads that of a reference signal f0 from a crystal oscillator 1 or not; while a phase control circuit 6 adds one bit to the signal f0 from the voltage-controlled oscillator 9 when the feedback signal leads the reference signal f0 or substracts one bit when the feedback signal lags behind the reference signal, the detection result is counted by an up/down counter 7, whose counting result is converted by the D-A converter 8 into a DC voltage to control oscillation frequency of the voltage-controlled oscillator 9. Therefore, the frequency-division ratio of the frequency divider 5 is vaired to vary a output frequency, thus generating the optional stable frequency with high purity.

IPC: G06F11/00
Filed: 1981-02-04
Abstract: PURPOSE:To make information transmission and receiving possible without waiting completion of correction of the error between discs, by giving the data error correction function to every disc. CONSTITUTION:If an information error occurs on a disc D1, a report indicating that the disc D1 enters into the correction operation because of the occurrence of the error is given to a controller 4. The controller interrupts temporarily transmission and receiving of information to and from the disc D1 to wait for the completion of correction until receiving this report. The error correction function is given to the disc side independently, and therefore, the controller 4 can execute another operation to transmit and receive information to and from other discs D2-Dn. When the error correction is completed in the disc D1, the disc D1 reports the completion to the controller 4. The controller 4 restarts transmission and receiving of information to and from the disc D1 after conclusion of transmission and receiving of information to and from discs D2-Dn.

Abstract: PROBLEM TO BE SOLVED: To miniaturize an abnormal temperature prevention device, reduce the cost, and stabilize the performance by commonly use a temperature sensor for detecting the temperature of an inner pan as a temperature detecting means for a heating control means and a heating stop control means. SOLUTION: When the detection temperature of a thermister THm of a temperature sensor becomes an abnormal state, the resistance value of the thermister THm becomes small, the voltage of an unreversed input terminal (+) of a first comparator CP1 becomes higher than the reference voltage in a reverse input terminal (-) and the output of the first comparator CP1 becomes 'L'. The voltage of the unreversed into terminal (+) of a second comparator CP2 is charged to a condenser C2 via a resistance R and discharged by a resistance R20 . Therefore, the input voltage of a reset circuit 41 becomes 'L', a control system of a microcomputer control unit 100 is reset, and the heating quantity control itself is made to stop so that energization to a cooking heater MH and a heat insulating heater SH is shut off and therefore the safety of the rice cooker main body can be secured.
