摘要： A variable delay circuit (101) generates a plurality of delay signals (D(1), D(2), . . . , D(n)). An output holding circuit (102) receives the plurality of delay signals (D(1), D(2), . . . , D(n)) in synchronization with a transition of a reference signal (Sref). A selector (104) provides an input signal (Sin) to the variable delay circuit (101) in a normal mode, and provides one of the plurality of delay signals (D(1), D(2), . . . , D(n)) to the variable delay circuit (101) in a calibration mode. A frequency measurement circuit (105) counts the number of transitions of one of the plurality of delay signals (D(1), D(2), . . . , D(n)) during a predetermined frequency measurement period. In the calibration mode, a delay-amount calibration circuit (106) adjusts a delay time of the variable delay circuit (101) so that the number of transitions counted by the frequency measurement circuit (105) approaches a target value corresponding to a frequency of the input signal (Sin).

摘要： In a PLL circuit including a VCO having a plurality of oscillation frequency bands, a TDC circuit calculates a phase difference between a predetermined reference signal from a fixed frequency divider and a PLL frequency-divided signal from a variable frequency divider. The TDC circuit detects the amount of time by which the phase of the PLL frequency-divided signal leads or lags with respect to that of the reference signal in one cycle of the reference signal, thereby detecting which of the signals has a higher frequency and which has a lower frequency. Therefore, for each oscillation frequency band, the frequency comparison is completed in one cycle of the reference signal, allowing an oscillation frequency band selection circuit to detect an optimum oscillation frequency band corresponding to a predetermined PLL output frequency in a short time.

摘要： To provide a piezoelectric actuator whereby impact resistance can be greatly improved without complicating the design or causing a reduction in drive efficiency. When a piezoelectric actuator 31 is incorporated into a main plate 14, an arm part 513 of a vibrator 50 is disposed across from a protrusion 144 via spaces SP1, SP2 having specific dimensions. With the presence of these spaces SP1, SP2, a free end FR moves freely within the spaces SP1, SP2 during driving, but a vibrating part 511 is captured at the free end FR by the protrusion 144 when external impact is applied, and the vibrating part 511 can therefore be prevented from moving beyond the dimensions of the spaces. Resistance against impact from falling can thereby be easily and greatly improved without reducing the drive efficiency, and the usual difficulty of reconciling both drive efficiency and impact resistance can be resolved.

摘要： N-piece redundant address comparing circuits are individually composed of impedance converting circuits, so that information using redundancy is transmitted as an impedance value. Consequently, even though the N becomes larger as the capacity of a memory becomes larger, a signal line having large capacitance and the node of a redundant judging circuit are not charged or discharged. A high-speed operation can be realized without being affected by the capacitance of the signal line or by the capacitance of the node of the redundant judging circuit.

摘要： A printing device, which is capable of printing image onto a tape-type recording medium along the longitudinal direction of the tape-type recording medium, is also capable of printing the image on the tape-type recording medium in a rotated fashion with respect to the longitudinal direction of the tape-type recording medium. When the image is printed with a certain rotation, it is discriminated whether a length of the image to be printed in the rotated fashion in the width direction of the tape-type recording medium is smaller than the width of the tape-type recording medium. Then the size of the image to be printed is reduced if the length of the image is greater than or equal to the width of the tape-type recording medium. It is further discriminated whether the length, in the width direction of the tape-type recording medium, of the image to be printed after reduced by the reducing means is smaller than the width of the tape-type recording medium; and alarm is actuated if the length of the reduced image is still greater than or equal to the width of the tape-type recording medium.

摘要： In a printing device for printing bar-codes, a string of characters and symbols representing the contents of the bar-codes are printed under the bar-codes by replacing the lower part of the dot pattern with the dot pattern for the string. The present invention is characterized in that the printing device has a decision means for deciding whether or not to print characters and for printing bar-codes with a sufficient height for reading operation by bar-code readers. The printing device automatically omits the string of characters when a character size set by an operator is not large enough to print a string and a bar-code in juxtaposition.
