摘要： A drive apparatus for a piezoelectric actuator prevents locking drive frequency in a state of resonance due to harmonics. There is no need to provide external components to filter, and circuitry can easily be reduced in size. The drive apparatus has a phase difference-DC conversion circuit to detect vibrating state of the vibrating body, a comparison circuit, a harmonics detection circuit to detect that the vibrating body is resonating due to harmonics and outputting a harmonics detection signal, an integration circuit to control the frequency of the drive signal supplied to the piezoelectric element of the vibrating body, a variable frequency oscillation circuit, and a drive circuit. The integration circuit, the variable frequency oscillation circuit, and the drive circuit control the frequency of the drive signal on the basis of the output of the comparison circuit when a harmonics detection signal is not outputted and continue to vary the frequency of the drive signal without controlling the frequency of the drive signal on the basis of the output of the comparison circuit when a harmonics detection signal is being outputted.

摘要： 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. By passing a shaft 21 through the insertion hole 22, the lever 20 is turnably supported so as to turn about its own axis. 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.

摘要： In a driver circuit for driving a pair of data lines, the amplitude of a differential input signal is reduced from 2.5 V to 0.6 V, which is smaller than a conventional lower-limit source voltage (approximately 1.5 V). The amplitude of the differential signal transmitted through the pair of data lines is amplified to 2.5 V by an amplifying circuit and the resulting signal is then latched by a latch circuit. After the latching by the latch circuit, the operation of the amplifying circuit is halted. The driver circuit is constituted solely by a plurality of NMOS transistors so as not to increase a leakage current flowing in the off state. Here, the threshold voltage of the NMOS transistor positioned on the ground side is reduced to a conventional lower-limit value (0.3 V to 0.6 V), while the threshold voltage of the NMOS transistor on the power-source side to a value lower than the above lower-limit value (0 V to 0.3 V), thereby enhancing a driving force of the NMOS transistor on the power-source side.

摘要翻译：在用于驱动一对数据线的驱动电路中，差分输入信号的幅度从2.5V减小到小于常规下限电源电压（约1.5V）的0.6V。通过一对数据线传输的差分信号的幅度被放大电路放大到2.5V，然后由锁存电路锁存所得到的信号。在锁存电路锁存之后，停止放大电路的工作。驱动电路仅由多个NMOS晶体管构成，以便不增加在断开状态下流动的漏电流。这里，位于地侧的NMOS晶体管的阈值电压降低到常规的下限值（0.3V〜0.6V），而电源侧的NMOS晶体管的阈值电压低于上述下限值（0V至0.3V），从而增强了在电源侧的NMOS晶体管的驱动力。

摘要： A tape printing apparatus having a test printing function for printing a predetermined test pattern onto a tape upon operation of an appropriate key includes a printing part, a tape width detector, a memory and a print control unit. The printing part prints the predetermined test pattern. The tape width detector detects the width of the currently loaded tape. The memory stores test pattern data by which to print any one of a plurality of different test patterns depending on the tape width detected by the tape width detector. The print control unit retrieves from the memory the test pattern data corresponding to the detected tape width upon operation of the appropriate key and causes the printing part to print the test pattern onto the tape based on the retrieved test pattern data. Because the tape printing apparatus prints the test pattern according to the width of the currently loaded tape, an operator can determine what printing is available for that particular tape.

摘要： An external power supply voltage V.sub.CC is applied to a peripheral circuit as a first internal power supply voltage V.sub.PERI. A power supply voltage control circuit outputs a voltage control signal V.sub.SIG of a high logic level if V.sub.CC is not greater than a low limit voltage V.sub.0L in a voltage range specified by VCC recommended operating conditions, otherwise it outputs V.sub.SIG of a low logic level. A power supply circuit applies a second internal power supply voltage V.sub.W and a third internal power supply voltage V.sub.WORD to a memory cell section. V.sub.W is equal to V.sub.PERI if V.sub.SIG is HIGH, while on the other hand V.sub.W is a voltage as a result of boosting V.sub.PERI. V.sub.WORD is a voltage as a result of boosting VW to a further extent. A row decoder sends out V.sub.W onto an enable signal line of a row of sense amplifiers, and V.sub.WORD onto a word line of a memory cell array so that V.sub.W becomes a high-logic-level data write voltage to a memory cell. This adequately prolongs the data-holding time with no sacrifice in memory cell voltage resistance.
摘要翻译：外部电源电压VCC作为第一内部电源电压VPERI施加到外围电路。如果VCC在VCC推荐工作条件下规定的电压范围内VCC不大于下限电压V0L，则电源电压控制电路输出高逻辑电平的电压控制信号VSIG，否则输出低逻辑电平的VSIG。电源电路将第二内部电源电压VW和第三内部电源电压VWORD施加到存储单元部分。如果VSIG为高电平，则VW等于VPERI，而另一方面，VW是VPERI升压的电压。 VWORD是由于将VW进一步升高而产生的电压。行解码器将VW发送到一行读出放大器的使能信号线上，并将VWORD发送到存储单元阵列的字线上，以使VW成为存储单元的高逻辑电平数据写入电压。这样就可以在不牺牲存储单元耐压的情况下充分延长数据保持时间。

The control device is responsive to the read-out character or graphic pattern data to control the operations of drives for feeding the paper along one axis, and reciprocating the carriage along another axis perpendicular to the one axis. The apparatus further comprises a display device which displays, in the writing mode, the keyed-in characters, and provides, in the plotting mode, messages relating to a procedure according to which data necessary to plot a graph is entered through the keyboard.
