摘要:
A processing device is provided with a circuit connected to a first conductive portion and a second conductive portion. An AC voltage source produces an AC waveform voltage obtained by adding a bias voltage to an AC voltage for capacitance measurement. The AC waveform voltage is applied between the first conductive portion and the second conductive portion through the measurement probes. The moment the AC waveform voltage is applied to the circuit with a switch closed, an inrush current flows through the circuit based on a potential difference of the bias voltage. This inrush current causes dielectric breakdown in the conductive resin, thereby securing the continuity of the conductive resin. With the continuity of the conductive resin secured, a capacitance of the piezoelectric body is measured by the AC waveform voltage, and it is determined whether or not the piezoelectric body is normal.

According to one embodiment, a luminaire is provided which can enhance the feeling of brightness of a space and can reduce glare. The luminaire includes an equipment mounted on a ceiling surface. The equipment includes a light source and a light control unit. When an amount of light emitted outside from the equipment is an equipment luminous flux, and a direction right under the equipment has a luminous intensity distribution angle of 0°, the light control unit controls to cause a luminous flux falling within a range of a luminous intensity distribution angle of 90° to 120° to be 20% or more of the equipment luminous flux and to cause a luminous flux falling within a range of a luminous intensity distribution angle of 60° to 90° to be 20% or less of the equipment luminous flux.

There is provided a physical property measuring method for a TFT liquid crystal panel, includes an impedance setting step of setting the impedance between the source and drain of a TFT of the TFT liquid crystal panel to be less than or equal to a predetermined value, a voltage application step of applying a voltage that cyclically varies to a liquid crystal layer of the TFT liquid crystal panel. And the method further includes a physical property measuring step of measuring a transient current flowing through the liquid crystal layer to which the voltage that cyclically varies is applied in the voltage application step to measure physical properties of the liquid crystal layer.

A lighting apparatus comprises a housing and a first reflector. The first reflector is mounted beneath the light source and includes a plurality of segmented reflectors, each having at its top, a installation hole and at its bottom, an opening wider than the installation hole. A second reflector is positioned beneath the first reflector. The height of the second reflector causes a first light shielding angle defined by a straight line passing through the installation hole and the bottom edge of the corresponding segmented reflector to be larger than a second light shielding angle defined by a straight line passing through the bottom edge of the segmented reflector and the bottom edge of the second reflector.

In encoding an interlace picture in a field picture, a motion-vector detecting apparatus changes over a reference picture of a P-picture in a field unit, and changes over a reference picture of a B-picture in a frame unit. Moreover, in detecting the motion vector in different predictive directions, the motion-vector detecting apparatus simultaneously carries out a process of the same reference picture by changing over original picture frames.
