摘要:
An electrical dimmer device and its driving method applicable to, for example, an image pickup unit and a display unit operate so that when a control signal for stop adjustment is changed from its current value of stop adjustment to a larger value, which occurs when the light transmissivity of a positive type liquid crystal is raised, or when the light transmissivity of a negative type liquid crystal is lowered, the control signal is temporarily varied to an intermediate value that is larger than the larger value. The energy of the varied larger value and a time during which that varied value is applied are determined in accordance with predetermined values. By doing so, it is possible to make a response speed when changing the light transmissivity extremely faster and thus attain a response time, of for example, one field period of time or less required for a stop mechanism of a video camera.

A light control device comprises a liquid crystal cell 12, and a pulse control unit 62 or 64 wherein when a transmittance of light transmitted from said liquid crystal element is changed from an actual light transmittance to an intended light transmittance, the pulse control unit is able to insert beforehand a drive pulse for control corresponding to a minimum light transmittance or a maximum light transmittance, at least, prior to application of a drive pulse corresponding to the intended light transmittance. A method of driving the light control device is also described wherein the light control device is driven by use of the drive pulse for control, along with a pickup device wherein the light control device is arranged in a light path of a pickup system.

An automatic analyzer uses probes for detecting liquid levels based on a capacitance detection method. Erroneous detection of liquid levels due to interference caused by the frequency difference of oscillators is reducted. When frequencies f1 and f2 of respective detector oscillators, which are originally equal to each other, are different by approximately several Hz from each other due to a manufacturing variation, oscillation waveforms are added to liquid level detection voltages, causing a premature determination that the probes have contacted the liquid surface before actual contact therewith. By setting the difference between the frequencies f1 and f2 of the detector oscillators to be in the range of several kHz, an oscillation waveform corresponding to the difference between the frequencies is added to the detection voltages, but the amplitude values of the high-frequency components are attenuated by high-frequency attenuators, thereby ensuring accuracy in the liquid level detection.

The purpose of the present device is to provide a simply-configured showerhead at a low price wherein the shower water is stopped simultaneously with the operation of the stop cock of the shower. Thus, sparing the user an unnecessary action of reattempting to turn off the stop cock. The showerhead comprises at least a body having a large channel and small channel defining a step and being in communication with each other. Further, nozzle is provided at one end of the showerhead and a water supply connection is provided at the other end. A partition tube may be inserted in the large channel to form an air-inflow chamber between the partition tube and the body. Thus, air may be introduced from an outer air-suction port into the water-inflow chamber through an inner air-suction port.

A slide door is provided to be movable between a closed position to cover a side opening formed at a vehicle-body side face and an open position. The slide door is configured to move outward and subsequently slide rearward along a rear vehicle-body outer face when the slide door moves from the closed position to the open position. There is provided a detection sensor to detect a foreign matter in coming into a gap from a vehicle-compartment inside. A drive of the slide door is stopped in case the detection sensor detects the foreign matter in coming into the gap when the slide door moves toward the open position. Thereby, any foreign matter can be prevented from being pinched in the gap formed between the slide door and the rear edge portion of the side opening.
