Abstract: A two-dimensional code printing apparatus includes a computer device and a tape printer. A print frame is arranged on a label making work area on an edit display screen displayed on the computer device. A user inputs a text into a text box arranged on the print frame, and then highlights the text to be coded in a two-dimensional code by a mouse, and then one-clicks a two-dimensional code button. Herewith, the text and the two-dimensional code are displayed on the text box. If the user clicks a print button, a label on which both the text and the two-dimensional code printed is printed.

Abstract: A PLL frequency synthesizer is provided with a linearization circuit 6 which receives an oscillation frequency control signal VT from a loop filter LF. The linearization circuit 6 outputs a charge pump current control signal CPCONT, depending on a potential level of the oscillation frequency control signal VT. The larger the value of the charge pump current control signal CPCONT, the higher the potential level. A charge pump CP receives the charge pump current control signal CPCONT, and causes a current corresponding to the value to flow in or out. Therefore, with a simple circuit structure, loop gain characteristics of the PLL frequency synthesizer can be regulated to be constant.

Abstract: 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.

Abstract: To provide a drive detection means for a piezoelectric actuator that can detect an amount driven without requiring adding an encoder or other component while also preventing increasing the load. A rotor is disposed eccentrically to the axis of rotation to change the pressure applied from the rotor to a contact part as the rotor is driven. When the pressure changes, the amplitude of the detection signal output from the detection electrode 18 of the piezoelectric element changes in conjunction with rotor rotation, and how much the rotor has been driven can be detected by detecting the amplitude change. Size and thickness can therefore be reduced because providing an encoder, switch, or other component is unnecessary, and current consumption can also be reduced.

Abstract: The number of lines of character strings to be printed on a cable label 11 is calculated (S730) and line spacing is calculated so that the distance between the lines of the character strings of the calculated number of lines will be equalized (S740). A print image rotated counterclockwise by 90 degrees is generated so that the character string will be in the width direction of the print tape 10 (S750). Printing is executed (S790) by successively arranging print images for the calculated number of lines while placing print images at both ends of the cable label 11 (S760) and securing the calculated line spacing.

A power-saving control circuit 400 controls drive of a date dial displaying a date when updating a date display, which has been stopped in a power-saving mode, to a current date at the time of transfer from the power-saving mode to the display mode.

Abstract: A diaphragm 10 is fixed to a base plate 102 by a screw 13. A lever 20 has a spring member 23, a rotor-fixing member 25, and an insertion hole 22 formed therein.

In a state in which the spring member 23 abuts against an eccentric pressure-adjusting cam 26, a pressing force for urging the diaphragm 10 via the rotor 100 is adjusted by turning the pressure-adjusting cam 26 so as to change an elastic force of the spring member 23.

Abstract: A piezoactuator has a diaphragm, and the diaphragm has flat piezoelectric elements that oscillate in a longitudinal oscillation mode and a sinusoidal oscillation mode. A first electrode for detecting oscillation in the longitudinal oscillation mode, and a second electrode for detecting the amplitude of oscillation in the sinusoidal oscillation mode, are disposed on the surface of the diaphragm. When the piezoactuator is driven with a drive signal, the phase difference of a first detection signal output from the first electrode and a second detection signal output from the second electrode is detected. The frequency at which the detected phase difference becomes the maximum phase difference is then obtained, and a drive signal of a matching frequency is applied to the piezoelectric elements.

Abstract: An adhesive layer is formed between a piezoelectric element and a baseboard by using an adhesive agent with a Shore D hardness of 80 HS or greater to couple the baseboard and the piezoelectric element. The adhesive layer is formed in a uniform thickness by placing two spacers on a transfer sheet and spreading the adhesive agent between these spacers. The baseboard and the piezoelectric element bonded together by the adhesive layer are heated in a pressed state to cause the adhesive layer to harden. The vibration loss in the adhesive layer can be reduced because the hardened adhesive layer has high hardness. In addition, variation in the vibration characteristics of a piezoelectric actuator can be reduced because the thickness of the adhesive layer is uniform.
