IPC: H03C3/04
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain a digital FM modulator in which a deviation in a center frequency of an FM modulation output due to a DC offset component is eliminated. SOLUTION: A multiplier circuit 1 multiplies a constant to decide a modulation 102 with an input signal 101, and an adder circuit 2 adds the output of the multiplier circuit 1 with a constant to decide a center frequency 103 and the sum is given to an averaging circuit 3, in which averaged sample data of the result of sum are obtained. A 1st subtractor circuit 4 subtracts a constant representing the center frequency 103 from the output of the averaging circuit 3 and a 2nd subtractor circuit 4 subtracts the result of subtraction from an output of the adder circuit 2. Based on the output of the 2nd subtractor circuit 5, an oscillated frequency of a reference oscillator of a direct digital synthesizer 6 is changed based on an output of the 2nd subtractor circuit 5. Then the oscillated frequency from which an offset is eliminated based on an input modulation signal 101 is controlled.

Title: Semiconductor memory
Inventor: MOCHIZUKI HIDENOBU
IPC: G11C7/06
Filed: 1989-05-25
Abstract: PURPOSE:To detect the potential change of a bit line at high speed by interposing a displacement transmitting means between the bit line and an inverter so that only the fluctuation of the bit line to the reference potential side of a potential can be transmitted to the inverter. CONSTITUTION:The input/output of an inverter In, which is a sense amplifier, is connected by a switching means SW and a capacity element C is interposed between the input terminal of the inverter In and the bit line. In such a case, by turning ON the switching means SW in an instant before reading, the input level of the inverter In can be biased to a threshold value. When a cell Mc is set in a conductive state, a current flows and a reference potential Vss is fluctuated for the potential of the bit line, the input level of the inverter In is fluctuated from the threshold value to the reference potential Vss side. Accordingly, the inverter In is speedily set in a state to output a signal corresponding to the stored contents of the cell Mc. Thus, the speed of reading operation can be extremely improved.

Filed: 1984-06-29
Abstract: PURPOSE:To certainly detect all of printing abnormalities, by removing an abnormality signal caused by the phase shift of the boundary part between the low and high density parts of a picture pattern by utilizing an optical shading-off phenomenon and adding differential signals with respect to picture patterns of plural continuous sheets to perform judgement. CONSTITUTION:An optical system is adjusted so that focus gets out of the light receiving surface of the photoelectric converter element provided to a detection part 4. By this adjustment, a reference signal and a detection signal gradually change (signals become obtuse) at a boundary part and, therefore, if the differential of both signals is taken, the pulse generated by a phase lens can be suppressed to a level considerably smaller than a tolerant range having a height and width accompanied by an optical shading-off amount, the density differential at the boundary part and a phase shift amount and the effect of phase shift can be removed. Therefore, signals obtained by the operation of differential corresponding to a definite number of sheets are added to perform treatment for discriminating whether the addition treatment result is present in the tolerant range.
