Abstract: An integral molding method of gasket of a fuel cell component member in which a gasket body is integrally molded with an outer peripheral portion of a membrane electrode assembly and a peripheral portion of an opening formed on the membrane electrode assembly by cross-linking molding using a mold having a heating means, the membrane electrode assembly comprising a proton exchange membrane, a gas diffusion layer integrally laminated on both sides of the proton exchange membrane via a catalyst carrier layer constituting an electrode. The mold has a cavity corresponding to a molding portion of the gasket body and a heat insulation zone corresponding to a power generating functional portion of the fuel cell component member, a not-cross-linked gasket material is filled in the cavity and the gasket material is molded by heat cross-linking molding using the heating means, whereby a heat generated by molding is prevented from being transmitted to the power generating functional portion by the heat insulation zone.

Abstract: An inkjet printer prevents the paper from lifting away from the platen when the suction action of the platen is stopped, and thereby prevents paper jams and other printing problems. The printer 1 conveys the printing paper 12a while holding the paper 12a to the surface of the platen 19 by a suction mechanism 50. After the automatic paper cutting operation is completed, the leading end part 12b of the printing paper 12a is retracted from the cutting position B to the printing start position A on the platen 19, and the printer 1 waits for the next print job with the printing paper 12a held against the platen 19. When a power conservation mode or power off mode is entered, the control unit 61 of the printer 1 advances the leading end part 12b of the printing paper 12a from the printing start position A to the cutting position B so that the paper is held by the downstream-side paper feed roller 34 and pressure roller 35, and then stops the power supply to the suction mechanism 50 of the platen 19.

Abstract: An oven-controlled crystal oscillator includes a circuit board, a crystal unit surface-mounted on the circuit board, and a temperature control circuit that maintains operating temperature of the crystal unit constant. The temperature control circuit includes a heating resistor, a power transistor that supplies power to a heating resistor, and a temperature sensitive resistor that detects temperature of the crystal unit. The heating resistor is formed, as a film resistor, on a surface of the circuit board in an area thereof in which the crystal unit is located. The temperature sensitive resistor is provided on the circuit board as a film resistor.

Abstract: A constant temperature crystal oscillator includes on a circuit substrate: a surface-mount crystal resonator which is provided with two crystal terminals as mount terminals and a dummy terminal on the bottom surface, and has a metal cover; an oscillation circuit element which forms an oscillation circuit together with the crystal resonator; and a temperature control element which keeps a constant operation temperature of the crystal resonator, in which the temperature control element includes at least a heating chip resistor, a power transistor for supplying electric power to the chip resistor, and a temperature sensitive resistor for detecting the operation temperature of the crystal resonator, wherein a dummy terminal on the substrate side of the circuit substrate for connection to the dummy terminal of the crystal resonator is connected to a resistor terminal on the substrate side to which the temperature sensitive resistor is connected through a conductive path.

Abstract: The roll paper printer of the subject invention has a control to detect failure of a paper detector in accordance with a method for detecting such failure. The printer 1 is constructed so that the paper transportation path is open when the cover 3 to the roll paper compartment 10 is open and includes a paper detector 40 and a control unit 30 to determine if the paper detector 40 is faulty. A failure warning is provided by a warning indicator 7(S7, 8) to indicate failure of the paper detector 40 when the cover 3 has been open continuously for at least a first set time (S6) and the output state of the paper detector 40 has not changed even once to a no-paper state within the first set time. Preferably, the printing operation of the printer 1 is disabled upon determining that the paper detector 40 is faulty to permit replacement of the paper detector. Problems attributable to paper detector failure, such as soiling the platen with ink can thus be prevented.

Abstract: 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.

Abstract: A method of manufacturing a plasma display panel, which comprises the steps of filling a barrier rib-forming paste containing glass frit in a barrier ribs-forming intaglio and concurrently forming a paste layer having a constant thickness on the intaglio, superimposing a substrate on the barrier ribs-forming intaglio filled with the barrier rib-forming paste containing glass frit to thereby transfer the barrier rib-forming paste onto the substrate, and heating the barrier rib-forming paste that has been transferred to the substrate, thereby burning out existing organic components and concurrently sintering the glass frit to thereby form the barrier ribs and dielectric layer. The plasma display panel manufactured by this method is featured in that the barrier ribs and the dielectric layer are formed using the same barrier rib-forming material containing a low melting point glass frit.

Abstract: An insulator body 310 is held in a semicylindrical metallic cover 320. The insulator body includes a main body portion having a planar plate-like contact support 312 extending forwardly from the front end of the main body portion. A plurality of narrow strip contacts 330 are arranged on the opposite plate surfaces of the support 312. Key bosses 314, 345 extend forwardly from the insulator body 310 in such a fashion as to sandwich the contact support 312 therebetween. A part of an annular groove is defined between key bosses 314, 345 and metallic cover 320 for receiving a tubular metallic cover of a connector plug. The key boss 314 has a keyway formed in the surface thereof opposing the contact support 312 The connector provides for accommodating an increased number of contacts and preventing coupling between different types of connectors, and allows for reducing the size of the connector.
