Title: Luminance signal demodulator
IPC: H04N5/93
Filed: 1992-03-27
Abstract: PURPOSE:To eliminate the inverting phenomenon of the demodulator by detecting the levels and frequencies of a synchronizing part and a video part, calculating the frequency characteristic of a high frequency emphasized signal at a microcomputer while using these levels and frequencies, and controlling the gain of a variable gain amplifier corresponding to a control signal based on this result. CONSTITUTION:A synchronizing part level detector 5 extracts a synchronizing part A by a synchronizing signal SYNC to be inputted, detects this level and transmits a signal SYL showing this level to a microcomputer 9. Similarly. a video part detector 6 extracts a video part B by the signal SYNC, detects this level and transmits a signal VL showing this level to the microcomputer 9 as well. A synchronizing part frequency detector 7 detects the frequency of the synchronizing part A, obtains a signal SYF showing an FM modulated frequency and similarly outputs this signal to the microcomputer 9. Similarly to the detector 7, a video part frequency detector 8 obtains a signal VF showing the luminance signal and outputs this signal to the computer 9 and at such a time, the value of the frequency characteristic is calculated by the respective values of these frequencies.

IPC: H02P7/288
Filed: 1979-06-11
Abstract: PURPOSE: To ensure prevention of occurrence of fire by preventing overheating which occurs in the case of stopping operation of the fan forcibly, by abolishing the use of a thermospring provided in a power transistor, and by connecting a thermistor to the system instead.  
     CONSTITUTION: The turn controller 20 is connected to the thermister 21 which has such a characteristic as to rapidly lower electric resistance at the time of ascent of temperatue and is provided in parallel with a transistor circuit 23 connecting the power transistor 22's base terminal B to an emitter terminal E through 2 transistors.

Title: Computer monitoring device
Inventor: KAWARASAKI YOSHIHARU
IPC: G06F1/28
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a computer monitoring device which can secure safe operation even when a power source voltage supplied to a microcomputer is lowered and the microcomputer is in abnormal state. SOLUTION: In order to supply the power with a microcomputer monitoring circuit 14 and a signal processing circuit 16 when a power source voltage supplied by a microcomputer power source 18 lowers, an auxiliary power source 20 for supplying a slightly lower voltage than the voltage the microcomputer 18 supplies is provided. If the power source voltage supplied by the microcomputer power source 18 lowers, a potential of the auxiliary power source 20 becomes higher than the potential of a point D and so the power is supplied with the microcomputer monitoring circuit 14 and the signal processing circuit 16 by way of a diode 26. Thus, since the microcomputer monitoring circuit 14 and the signal processing circuit 16 can successively operate, it is possible to perform processing for securing safe operation.

Title: Signal detection circuit
Inventor: SATO TOSHIYUKI
IPC: H04Q1/44
Filed: 1990-03-20
Abstract: PURPOSE:To increase the possibility of establishing phase locking sufficiently even in an input signal with a short consecution time by multiplying a signal frequency in an input signal consecutive time by a number of gradual multiple. CONSTITUTION:A frequency multiplier circuit 100 outputs an output signal S100 multiplying a frequency of an input signal S1 by a predetermined gradual multiple number N. A phase lock detection circuit 300 compares the output signal S100 of a frequency gradual multiple circuit 100 with a frequency signal S200 of a phase locked loop circuit 200 and the phase locked loop circuit 200 detects whether or not the state is in the phase lock establishing state to detect a frequency component of 1/N component included in the input signal S1. Thus, since the signal period number in an input signal consecutive time is multiplied by the number of gradual multiple, the possibility of establishing the phase lock sufficiently is increased even in the input signal with a short consecutive time and the signal detection capability of the signal detection circuit is considerably improved.
