Title: Lc oscillation circuit
Inventor: SUGANO MAKOTO
IPC: H03B5/08
Filed: 1980-03-14
Abstract: PURPOSE:To avoid the effect of stray capacity produced on the line to which a resonance circuit and amplifiers are connected, by zeroing the input impedance of the amplifiers. CONSTITUTION:An inverting signal is given to an inversion amplifier 22 via a resistor 32. The potential of an inverting input terminal is in coincidence with a noninverting input terminal because the noninverting terminal is grounded. That is, the input impedance is 0. At the resonant frequency of a resonance circuit 26, since the impedance of the resonant circuit 26 is sufficiently great, the negative feedback extent through the resonant circuit 26 is sufficiently small, the gain of an amplifier 23, resonance circuit 26 and resistor 32 is sufficiently great, the output is positively fed back to the amplifier 23 through a phase inverting circuit 27 and oscillation is caused. The impedance at both ends of the circuit 26 is sufficiently small, and the line tying the circuit 26 and the amplifier 23 is not affected by the oscillating frequency.

Title: Icing preventing device
Inventor: MASUDA NOBORU
IPC: G01K7/34
Filed: 1990-02-14
Abstract: PURPOSE:To detect an icing state with high accuracy and to efficiently use heater driving electric power by extracting a signal corresponding to a shift in turning point as a detection signal. CONSTITUTION:When dew condensation occurs in the outer peripheral area of a refrigerant pipe1, a resonator 13 shifts in tuning point owing to the variation in dielectric constant between a detection electrode 9 and a ground electrode 4 and the output voltage of a detecting circuit 14 is dropped. When the temperature further is lowered, the dielectric constant between the electrodes 4 and 9 is decreased and the Q damping of the resonator 13 is generated. When the entirety enters an icing state, a difference in tuning point generated between the dew condensation state and icing state is produced. When the temperature in the icing area further is lowered and the output voltage of an operational amplifier 15 exceeds its threshold voltage, a relay circuit 20 is activated to close a switch 6. Consequently, a current flows from a power source 5 to a heater 3, which is driven for heating.

Abstract: PURPOSE:To improve the permissible range to a pulse width distortion of an input data by applying OR calculation processing to an output data obtained through the operation of a positive logic clock and a synchronization clock and an output data obtained through the operation of a negative logic clock to the same input data and the synchronization clock. CONSTITUTION:A data inputted from a data input terminal 1 is divided into two, the one is fed to a data sampling circuit A and the other is fed to a sub data sampling circuit A'. The sampling circuit A samples the input data by a positive logic clock. On the other hand, the sub data sampling circuit A' samples the input data by a negative logic clock, a sub synchronization pulse generating circuit C' uses a data edge detection signal from a sub data edge detection circuit B' as a reset input and generates a repetitive pulse synchronously with the output of an FF 2b. Then an adder circuit G applies the OR calculation processing to outputs of a synchronizing pulse generating circuit C and the sub synchronization pulse generating circuit C'. Thus, the permissible range of an input data with respect to the pulse width distortion is expanded without varying the basic clock.
