    摘要: A temperature control circuit of oven-controlled crystal oscillator includes a heater resistor, a first resistor, a thermistor, a second resistor, a third resistor, a differential amplifier, a PNP-type power transistor, and a PNP-type current-limiting transistor. The thermistor outputs a voltage depending on a temperature. The differential amplifier amplifies a difference between the voltage received by the one input terminal and the voltage received by the other and output as a control voltage. The PNP-type power transistor includes an emitter where the other end of the heater resistor is connected, a base that receives an output of the differential amplifier, and a grounded collector. The PNP-type current-limiting transistor has an emitter where a power voltage is supplied, a base that receives a voltage between the other end of the heater resistor and the emitter of the power transistor, and a collector connected to the base of the power transistor.

    摘要: A printer and reprinting control method do not reprint when an error accompanied by no damage to the actual printing area or print image on paper occurs so that consumables are not wasted. The printer reprints the label on which the print image was being formed when a specific error occurs if the error occurred while the inkjet head was forming the print image in the actual printing area of the label. When the non-printing area of the label is passing the printing position of the inkjet head, the print image in the actual printing area that was printed immediately before an error occurs is reprinted only if a specific error is detected, such as a paper jam error or mechanical error with the possibility of damage to the paper or label.

    摘要: A device for intermittently ejecting a fixed quantity of a mixed gas, to which a liquid is added, to a target object. A device comprises a gas supply means (2) to which a carbon-dioxide-gas container (B) is mounted, a chemical liquid supply means (3) to which a chemical liquid container (M) is mounted, an ejection means (5) for mixing a supplied high-pressure gas and a supplied liquid together and ejecting the mixed gas, and an operation means (1). The device is adapted such that the high-pressure gas and the liquid are introduced into the ejection means (5) by operation of the operation means (1) and the mixed gas containing the liquid is obtained from the ejection means (5). The operation means (1) generates compressed air by operation of a pressing button, causes the compressed air to activate an operation section for the gas supply means (2) and for the chemical liquid supply means (3), obtaining a fixed quantity of the high-pressure gas and the liquid, and ejects in a pulse pattern a fixed quantity of the mixed gas from a nozzle, which is the ejection means (5).

    摘要: A cleaning mechanism for cleaning a print head in an inkjet printer with the print head having ink nozzles for discharging ink including a drive control unit which operates the cleaning mechanism at a first process level or a second process level that consumes less ink than the first process level; a timer which counts the elapsed time passed in which the print head is in a no-printing state; and a process selection unit responsive to a predetermined input cleaning command for selecting the first process level when the no-printing state has continued for less than a predetermined time or the second process level when the no-printing state has continued for greater than the predetermined time, based on the value of the timer when the predetermined input cleaning command is received. The predetermined input cleaning command can be received from a cleaning button or from a host computer. The drive control unit operates the cleaning mechanism at the process level selected by the process selection unit according to the predetermined input cleaning command.
