IPC: H04B1/26
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To fix the C/N ratio of a frequency synthesizer device with respect to the oscillation frequency of a voltage-controlled oscillator. SOLUTION: A PLL synthesizer is constituted of a first frequency divider 2, a phase comparator 3, a loop filter 4, and a second frequency divider 5. A frequency dividing ratio control circuit 6 controls the frequency-dividing ratio of the first frequency divider 2, so that the ratio changes with time and the time average value of the frequency dividing ration contains a decimal fraction. When the oscillator 1 is made to generate a specific frequency, a signal obtained by delaying the phase of the output signal of the first frequency divider 2 is used as the clock of the control circuit 6. The variation of the C/N ratio of the synthesizer can be eliminated by means of the frequency of the oscillator 1, and the locking-up time of the synthesizer device can be shortened.

Abstract: PURPOSE:To improve converting accuracy even if a characteristic of a transistor (TR) has a difference and to decrease the number of components by constituting the circuit with a TR operated as an emitter follower, flowing the same current to the TR of the same conduction type and cancelling the difference between the base and emitter between the TRs. CONSTITUTION:A voltage nearly equal to a potential drop component V2 of a resistor 5 is applied across a resistor R2 via TRs Q3, Q4 constituting the emitter follower, the voltage is converted into a collector current of the TRQ4, the current is converted again into a voltage by a resistor R1 and outputted via the emitter follower comprising a TRQ2. On the other hand, the potential drop V1 of the resistor 4 is outputted via a TRQ1, a resistor R1 and the TRQ2. Since each emitter current of the TRs Q2, Q3 is equal to that of a constant current source IB, a base-emitter voltage VBE of both the TRs is made equal. The emitter current of the TRs Q4, Q1 is made nearly equal by setting sufficiently to a small value of the constant current IS, the relation of VBE1=VBE2 is attained. Moreover, the resistors R1, R2 are made equal. Then the balanced inputs V1, V2 are converted into an unbalanced signal V3.

Filed: 1990-02-05
Abstract: PURPOSE:To simplify the check of the printing quality of the bar code labels by providing a function which turns the reading image data on the bar code labels into the count value and outputs this count value. CONSTITUTION:A character recognizing part 2 converts the data given from an image input part 1 into the corresponding character recognition data and sends this data to a host device via a switch part 4 and a data output part 5.

This part 3 counts the data given from the part 1 and sends the black/white count value data to the host device via the parts 4 and 5. The user compares the black/white count value data received from the part 3 with the data defined to the bar code label. Thus it is possible to easily check the printing quality of the bar code label when this label is unreadable.
