    摘要: Pressurized filtered exhaust air from a motorized fan in a vacuum cleaner body passes on an exhaust path to a floor suction tool. The exhaust air is directed by the floor suction tool generally parallel to the surface to be cleaned to agitate dust and thus to improve cleaning performance. An electric motor in the floor suction tool drives a rotation brush. The exhaust air is also directed toward the rotation brush in the floor suction tool in a direction to add rotation force to the rotation brush. Feeder lines to the electric motor pass through the exhaust path so that the feeder lines are exposed only to filtered air. Passing the feeder lines through the exhaust path avoids the necessity to make special provision for the feeder lines. The exhaust path passes along a hose, and may optionally pass along one or more extension pipes on its way to the floor suction tool.

    摘要: The present invention intends to improve the accuracy of temperature measurement when measuring the temperature of a semiconductor wafer by a radiation thermometer on the basis of the idea of virtual blackbody simulated by multiple reflection of light. A system includes a wafer (W), a circular reflector 1 of a radius R disposed opposite to the wafer (W), and a probe (2) disposed in a through hole formed in the reflector (1). The probe (2) is a through hole. The radiation intensity of radiation passed the through hole is determined by image data provided by a CCD camera disposed behind the back surface of the reflector (1). An error in measured radiation intensity of radiation falling the probe (2) due to light that enters a space between the wafer (W) and the reflector (1) and a space between the reflector (1) and the probe (2) and light leaks from the same spaces is corrected, the emissivity of the wafer (W) is calculated and the temperature of the wafer (W) is determined.

    摘要: A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.

    摘要: A driving device, which drives a display section that consists of a plurality of liquid crystal display elements that are connected to signal lines and scanning lines and that are disposed in the form of matrix, includes a scanning-line driver, a signal-line driver, and a compensating device. The scanning-line driver is for releasing to the scanning lines a scanning signal for selecting the scanning lines successively. The signal-line drive is for releasing to the signal lines a display signal for displaying images in synchronism with the scanning signal. Finally, the compensating device which, during a compensating period that follows a display period during which display signals corresponding to one picture are transmitted to the signal lines, applies to each liquid crystal display element a compensating voltage or compensating pulses that is capable of cancelling a lowering in an effective value of a driving voltage for the liquid crystal display elements during the display period. With this arrangement, since the lowering of the effective value of the driving voltage is cancelled, it becomes possible to display liquid crystal images in high quality.

    摘要: A signal transmitting apparatus using orthogonal frequency division multiplexing includes an inverse fast Fourier transform circuit for converting a digital information signal into a first multi-value QAM modulation signal. A guard interval setting circuit is operative for periodically generating a guard interval signal equal to a time segment of the first multi-value QAM modulation signal, and inserting the guard interval signal into the first multi-value QAM modulation signal to convert the first multi-value QAM modulation signal into a second multi-value QAM modulation signal. A clock signal generating circuit is operative for generating a first clock signal which drives the inverse fast Fourier transform circuit, and generating a second dock signal which drives the guard interval setting circuit. The inverse fast Fourier transform circuit includes a device for generating a pilot signal which corresponds to a given-order carrier, and adding the pilot signal to the first multi-value QAM modulation signal. The pilot signal has a predetermined frequency and an angle modulation component which remains constant over a plurality of symbol periods. The pilot signal corresponding to a given integer times its wavelength or a given odd number times its half wavelength is present in a guard interval occupied by the guard interval signal in the second multi-value QAM modulation signal. The pilot signal is continuously present over the guard interval and another interval.
