Title: Cross color reducing device for brightness signal chrominance signal separator
Inventor: NISHIGORI YOSHIHISA
IPC: H04N9/78
Filed: 1993-05-31
Abstract: PURPOSE:To reduce the production of a cross color by detecting a high frequency brightness signal for a short period leaked in a chrominance signal, thereby suppressing the chrominance signal. CONSTITUTION:An output signal from an adder 104 from a time t+7 to a time t+10 is larger than a threshold level (2) and a signal before the time t+6 after the time t+12 is smaller than a threshold level (1). Thus, when an output of a comparator circuit (1) 105 is a signal at the time t+17, an output from an AND circuit (4) 118 and an AND circuit (3) 124 is logical 1 and an output of the AND circuit (4) 124 is logical 1 and cross color is discriminated. Only in this case, an output of an inverting circuit 126 is logical 0 and an output of an averaging circuit 127 is smaller than logical 1, and a multiplier 128 multiplies the output signal with a color signal inputted from an input terminal 101 delayed by 8 clock periods for time adjustment to suppress a chrominance signal (cross color). When the chrominance signal is in existence for a short period only, it is discriminated to be the occurrence of cross color and the chrominance signal is decreased.

Title: Phase shift circuit
Inventor: YASUE KIYOU
IPC: H03B5/00
Filed: 1989-05-23
Abstract: PURPOSE:To limit a change in the decreasing direction of the phase by using parallel connection transistors(TRs) for phase control TRs so as to employ unbalanced configuration. CONSTITUTION:A control voltage from a ceramic oscillator is fed from a terminal A to bases of TRs 4, 5 and 8, 9 and from a terminal B to bases of TRs 6, 7 and the phase of an output from an output terminal E is controlled. The TRs 4, 5 and 8, 9 connected in parallel form desired unbalance characteristic for the phase control TRs. Thus, even when a ceramic oscillator output with a characteristic with a large frequency reduction is used at a phase decreasing side, the control to the phase retarding side is reduced, a change in the decreased frequency is limited to prevent destruction of the output TR.

Abstract: PURPOSE:To obtain the characteristic of an photoelectric transducing operation correctly, by utilizing the fact that a photocurrent depends on an applied voltage, and solving a specified expression by numerical computation. CONSTITUTION:For example, a plurality of lower electrodes 2 are formed with Cr on a glass substrate 1. An i-a-Si layer 3 covers the electrodes. A p-a-Si layer 4 forms a barrier together with the layer 3. An ITO is used for an upper electrode 5. A photodiode is formed by the layers 3 and 4 and the electrodes 2 and 5.

In this expression, Va is a voltage, which is applied to the photodiode; V0 is an output voltage; Cd is the capacitance of the diodes: Cs is the synthesized capacitance of wiring capacitance and the input capacitance of an amplifier; and Iph is a photocurrent, which flows from the diode when light is projected. The following expression is obtained from the expression I. The expression is solved by computation, and the characteristic of the photoelectric transducing operation, which agrees with the actually measured value, can be obtained. Namely, the expression is V0={1/(Cd+Cs)} {Iph(V1)DELTAt+Iph(V2)DELTAt...+Iph(Vn)DELTAt}, where n.DELTAt=Ts (accumulated time) and Iph(Vn) is the value of the photocurrent at the applied voltage Vn.
