Abstract: In a thermal transfer printer driven by a battery power source, to perform a print operation, the remaining capacity level of the battery power source (remaining battery capacity level) is detected by a voltage detector immediately before paper is fed out of a paper cassette and transferred for printing. The detected remaining battery capacity level is compared with a criterion level, which is a print-driving power required for one sheet of paper. If the remaining battery capacity level is lower than the criterion level, control is performed to stop the commencement of a print-driving operation. Thereby, the battery-driven printer averts printing from being terminated partway because of depletion in the battery power, and furthermore, enables printed sheets of the paper to utmost be increased.

Abstract: If printing is commenced while a relay is supplying power supply voltage from a battery to a power supply controller, a control circuit outputs a power supply switching prohibition signal to a permission/prohibition circuit. Even if an AC adapter is connected during printing, the relay will not be switched by an ON signal from an input voltage determination circuit. Once the printing is completed, the power supply switching prohibition signal is stopped, and a switch is made to power supply input from the AC adapter. As a result, even if an AC power supply is connected during printing, this will not cause the printing to take a longer time, and will prevent a decrease in printing quality.

Abstract: The present invention relates to a resistance welding method suitable for use in spot welding between a steel-base metal sheet, which has been plated for rust prevention purposes, and an aluminum-base metal sheet and aims to permit a current to flow at a high density across the plated steel sheet and the aluminum-clad steel sheet, thereby realizing high-quality welding.An aluminum-clad steel sheet comprised of a steel layer having projections and an aluminum layer is interposed between the plated steel sheet and the aluminum-base metal sheet to be welded to each other. An electrode is energized by a predetermined weld current from an alternating power supply. The current path is limited to the area of the projections, and metallic melt formed by melting of the plating is accommodated between the projections, preventing the current-carrying area from being increased.

Abstract: When forming a zinc-deposited base material for metallized capacitors, a primer layer for zinc-deposition made from at least one compound selected from the group comprised of an oxide of silicon, titanium and zirconium is formed on at feast one side surface of a base body comprised of a film or a thin condenser paper. Next, a zinc-deposited layer is formed on top of the primer layer. Then, a protective layer made from at least one compound selected from the group comprised of silicon-based oil, fluoro-based oil, alkylnaphthalene, polydiphenylether, fatty acids, fatty acid salts and paraffin wax is formed on top of the zinc-deposited layer. In this way, it becomes possible to form a zinc-deposited base material having excellent moisture resistance when used for metallized capacitors.

Abstract: A Coulomb-blockade element includes a silicon layer formed on a substrate through an insulating film. The silicon layer includes a narrow wire portion and first and second electrode portions. The narrow wire portion serves as a conductive island for confining a charge. The first and second electrode portions are formed to be connected to the two ends of the narrow wire portion and are wider than the narrow wire portion. Each of the first and second electrode portions has constrictions on at least one of the upper and lower surfaces thereof, which make a portion near the narrow wire portion thinner than the narrow wire portion.

Abstract: To receive a response signal from a radio card, a card reader transmits a carrier (not modulated) to the radio card. In the radio card, a phase modulator phase-modulates the a sub-carrier with a response signal, thereby generating a PSK signal, and a phase modulator phase-modulates the carrier with the PSK signal, producing a PSK-PSK signal. The PSK-PSK signal is supplied to an antenna via a signal-extracting device. The antenna sends the PSK-PSK signal toward the card reader. In the card reader, a distributor distributes the PSK-PSK signal to a synchronous detector and an orthogonal detector. The detectors performs synchronous detection by using carriers which differ in phase by 90.degree.. Low-pass filters extract sub-carrier components from the outputs of the detectors. The sub-carrier components are delayed and detected by delay detectors and added together by an adder.

The in-phase component and the orthogonal component are multiplied with carrier signals to obtain a carrier in-phase component and a carrier orthogonal component. The carrier in-phase component and the carrier orthogonal component are synthesized to obtain a VSB modulation signal.

Abstract: A sampling frequency conversion apparatus according to this invention converts an input data string based on an input sampling pulse into a data string based on an output sampling pulse having a frequency different from the frequency of the input sampling pulse. The apparatus reproduces the input sampling pulse based on the input data string, generates interpolation sampling pulses having a frequency corresponding to an integral multiple of the frequency of the input sampling pulse, and generates an interpolated data string from the input data string on the basis of the interpolation sampling pulses. On the other hand, the apparatus phase-modulates the output sampling pulse to diffuse its frequency spectrum, and selects and determines a timing of the interpolation sampling pulse closest to the timing of the phase-modulated output sampling pulse. The apparatus selects data corresponding to the selected timing from the interpolated data string, and outputs the selected data.

Abstract: A method and apparatus for resistance welding in which, while both or one of the electrode center axes of a pair of opposing electrodes is inclined with respect to the electrode forcing axis, the electrode tip of the electrode is intermittently pivoted about the electrode center axis for welding. The contact between the electrode tip and workpiece is moved at a preset number of welds to define a next contact surface on the face of the electrode tip, and thus the number of welds (electrode tip life) is considerably improved.
