Filed: 1990-04-19
Abstract: PURPOSE:To attain changeover of a high frequency at high speed by controlling the change in the phase shift of a variable phase shifter based on the phase error of a phase frequency comparator. CONSTITUTION:The phase and frequency of the output of a reference frequency oscillator 2 frequency-divided by a 1st frequency divider 3 and those of output of a voltage controlled oscillator 4 frequency-divided by a 2nd frequency divider 5 are compared at a phase frequency comparator 1. Then the frequency error DELTAF outputted from a terminal A is smoothed by a loop filter 6 and its output voltage controls the output frequency of the voltage controlled oscillator 4 to obtain a required output frequency. On the other hand, the phase shift quantity of a variable phase shifter 7 is varied based on a shift error DELTAP obtained by comparing the output of the reference frequency oscillator 2 with the output of the voltage controlled oscillator 4 from the terminal B of the phase frequency comparator 1 to be controlled so that the phase shift error of both the outputs is made zero. Thus, the time of the phase pull-in region is reduced and the frequency is switched at fast speed.

IPC: G02F1/1333
Filed: 1988-04-26
Abstract: PURPOSE:To eliminate a shadow of a wire which is the cause of deterioration of an image, by deflecting an electron beam for passing through the vicinity of a wire of a secondary electronic collector electrode, by a voltage applied to the secondary electronic collector electrode, and radiating the electron beam to an area of a shadow on the surface of a target. CONSTITUTION:Plural parallel wire parts 102 of a collector electrode 66 are fixed to a rectangular ceramic frame 80 to which a frit seal is attached. When the potential by which an electron beam for passing through the vicinity of each wire part 102 is displaced from an irradiated position when the electron beam is not deflected by a distance X being roughly equal to 1/2 of the diameter of a wire 78 is applied to the electrode 66, a shadow of the wire can be eliminated substantially. In such a way, the electron beam passes through both sides of the wire part 102, and deflected by the distance X, therefore, under the wire part 102, a roughly uniform charge is distributed. As a result, all areas on the surface 45 of a target can be brought to an address designation by a write electron beam 60a, and also, can be driven to an ON state, therefore, deterioration of an image caused by a shadow of the wire can be eliminated.

Abstract: PURPOSE: To correct accurately an A/D conversion error by providing a reference voltage generating circuit, measuring the error of an input reference voltage in advance and correcting an A/D conversion value of an analog input signal based on the measured error. CONSTITUTION: When a resistance RL of an external resistor 1 is set to the same as a resistance R1 of a ladder resistor 6, an input reference voltage VREF is VDD/2. When the voltage of a sample-andhold circuit 10 is VDD/2 and a digital value equivalent to a full scale is stored in a conversion register 12, after the end of reference voltage conversion, a digital value d/2 is stored in the conversion register 12. When the resistance of the external resistor 1 and the ladder resistor 6 is in excess of the tolerance, a digital value d0 is stored in the register 12. The value d0 is read by a CPU of a microcomputer 12 and an arithmetic circuit of the CPU conducts arithmetic processing to the value and a correction value is calculated. Thus, even when the resistance of the ladder resistor is in excess of the tolerance, an A/D conversion error is accurately corrected.

Abstract: PURPOSE:To prevent production of analog noise by applying delay circuit initialization based on a zero detection output representing zero state of an input signal for a prescribed period and result of comparison of outputs of 1st stage and end stage delay circuits of a noise shaper. CONSTITUTION:In case of infinite zero where an input signal is zero for a prescribe period, it is detected and an output of a zero detector 9 goes to logical '1'.
