Title: Cmos type input buffer circuit of semiconductor device
Inventor: YOSHIMORI TAKASHI
IPC: H03K19/0185
Filed: 1989-07-13
Abstract: PURPOSE:To prevent a through current from flowing through a semiconductor device of this design even at the transition of the device from a normal operation mode to a battery backup mode by a method wherein a first switching element, which turns ON when the device concerned is in a normal operation and OFF when in a battery backup mode, is provided. CONSTITUTION:When the whole device is changed to a battery backup mode, a control signal turns from H to L in level with the timming of transition. Therefore, a transistor Tr3 changes from an OFF to an On state, and a transistor Tr4 changes from an ON to an OFF state. As the transistor Tr4 is in an OFF state, no through current flows from a power source VCC to a ground even if any voltage is applied to an input terminal IN at the transition of the whole device in mode. Therefore, in an inner circuit in a following stage, a through current based on an intermediate potential is prevented from being induced. By this setup, at the transition of a device from a normal operation mode to a battery backup mode, a through current can be prevented from flowing through the device.

Filed: 1994-08-02
Abstract: PURPOSE:To require only one burn-out detecting circuit and to execute highly accurate thermocouple signal measurement by connecting the burn-out detecting circuit to the output side of a thermocouple signal selecting switch. CONSTITUTION:Since the burn-out detecting circuit B1 is connected to the output side O1 of the thermocouple signal selecting switch 1 to which plural thermocouples T1 to Tn corresponding to n channels are connected, the existence of burn-out (disconnected state) in each channel switched by an external signal 3a is eletected by the common burn-out detecting circuit B1 connected on the output side. On the output side, output data 4a in a thermocouple signal measuring mode are A/D converted by an A/D converter 5 through an amplifier 4 and inputted to a computer 3 as converted data. Since respective channels are mutually insulated, noise inserted into one channel does not exert adverse influence to other channels.

Abstract: PURPOSE:To suppress heating by signal current by making one of an induction coil and a voice coil with a superconducting material so as to attain sound reproduction with fidelity over a wide frequency band. CONSTITUTION:A signal current is supplied to an induction coil 2 arranged opposite to a voice coil 3 closely in a diaphragm 4 in which the voice coil 3 whose part is placed in a DC magnetic field formed by a magnetic circuit section 1 supported movably is fitted.

Title: Second service protecting system of control terminal
Inventor: KUMAZAKI MASAYUKI
IPC: G05B9/02
Filed: 1981-11-16
Abstract: PURPOSE:To hold the output signal of a protecting part of the second service which is obtained immediately before a power supply is lost and to facilitate an easy operation in a recovery mode of the power supply, by providing an analog holding function also to the inside of a control system containing a pneumatic control terminal. CONSTITUTION:The deviation of output signals between a control system 7 and a protecting part 8 of the second service which occurs when a power supply is lost at the part 8 is detected by a deviation monitor 14. A transfer relay 16 is switched to the side of an analog holder 15 within the control part 7, and therefore the output signal of the part 7 is held at a level that is obtained immediately before the power supply is lost. When the power supply is recovered, a  locking solenoid valve 4 is locked continuously since an analog holder 1 of the  part 8 is initialized. In this case, the output signal of the holder 1 is increased  and decreased through a control station. Thus the monitor 14 stops to detect the deviation when the coincidence of the output signal is obtained between a control part 2 and the part 8. As a result, the locking state due to a solenoid 5 is released with the signal obtained immediately before a control terminal is locked. Thus a control driver 6 is reset to its normal state.

Title: Method and device for information signal recording and reproducing
Inventor: OOTA YOSHIHIKO
IPC: H04N9/82
Filed: 1983-09-30
Abstract: PURPOSE:To obtain both satisfactory sound volume and a picture with simple constitution by performing simultaneous record/reproduction for a recording track for frequency divided multiplex signal of a low band conversion record system and a track where the high band frequency component of a color video signal is recorded directly. CONSTITUTION:Both luminance and carrier signals are separated from a color video signal through an AGC10 and a BPF9 respectively. The luminance signal is converted into an FM luminance signal through FM modulation 14; while the carrier signal is converted into a band lower than the FM luminance signal through an LPF22. These FM luminance signals are mixed with a low band conversion carrier color signal. Then a frequency divided multiplex signal is recorded to the 1st track of a magnetic tape by heads HA1 and HA2. While a bias signal obtained from the output signal of an oscillator 42 is superposed 41 on the high frequency component obtained by transmitting the color video signal through an HPF12. Then this superposed frequency component is written to the 2nd track of the magnetic tape. In such a way, the 1st and 2nd tracks are set in a pair, and color video signals are recorded successively in the same track pitch as the recording track of the using VTR and then reproduced for each track of said pair unit.
