Abstract: A wireless input apparatus includes a transmitting section responsive to turning-on of a switch for transmitting a prescribed signal, and a transmission control section for measuring a time period during which an on state of the switch continues, and inhibiting the transmission by the transmitting section when the measured time period becomes equal to a prescribed time period.

Abstract: A transistor includes a source region; a drain region; a channel region interposed between the source region and the drain region; and at least a first gate electrode and a second gate electrode provided on the channel region. At least one of the first and second gate electrodes traverses substantially an entire width of the channel region. At least another one of the first and second gate electrodes traverses a part of the width of the channel region.

Abstract: To provide a small polishing means featuring high machining efficiency that is capable of efficiently and quickly mirror-polishing an outer periphery of a chamfered workpiece (5) by bringing the outer periphery into even contact with a plurality of polishing drums (2, 2) at the same time. In an apparatus for polishing an outer periphery by bringing an outer periphery of the workpiece (5) retained by workpiece retaining means (3a, 3b) into contact with two polishing drums (2, 2) simultaneously to perform mirror polishing, the workpiece retaining means (3a, 3b) are supported by a sliding mechanism (16) such that they may move in a direction in which the two polishing drums (2, 2) are arranged, thereby to form an aligning means. In addition, the workpiece retaining means (3a, 3b) are provided with loading means (30) for absorbing a force applied to the workpiece retaining means in an X direction, the force being generated due to contact between the rotating workpiece (5) and the polishing drums (2, 2).

Abstract: A microwave heating apparatus includes a heating chamber 3 for accommodating an item 2 to be heated; a microwave generator 11 for radiating microwaves to the heating chamber 3, and a vapor generator 12 for supplying vapor to the heating chamber 3. The heating chamber 3 includes regenerating plates 28a and 28b for generating and regenerating heat when radiated by the microwaves from the microwave generator 11, thereby reducing dew condensation caused by the vapor in the heating chamber 3.

Abstract: An ultrasonic flowmeter includes a flow path defined by four wall sections, a flow measurement section, a calculation section and a pair of ultrasonic oscillators for transmitting and receiving an ultrasonic wave over a distance. The flow path is configured to reduce the influence of a phase difference, which results from the varying propagation distances of a direct wave and a reflected wave, by changing one or more of the flow measurement section configuration, the ultrasonic wave frequency, the orientation of the ultrasonic oscillators, and the distance between the pair of ultrasonic oscillators. A measurement section is suitably configured to measure the propagation time of the ultrasonic wave propagating between the pair of ultrasonic oscillators. Additionally, a calculation section is suitably configured to receive measurements from the measurement section and to calculate the fluid flow in the flow measurement section.

Abstract: A reproduction apparatus includes: a signal reading section for reading a signal recorded on a recording medium, the signal including a digital signal and an analog signal; a control signal reading section for reading a control signal recorded on the recording medium and including information representing a time mode indicating a run speed of the recording medium; a first determination section for determining the time mode based on an output of the control signal reading section; and a second determination section for determining whether the signal read by the signal reading section is a digital signal or an analog signal after the time mode is determined by the first determination section.
