摘要:
An XY-address solid-state image pickup apparatus comprises a pixel array made up a plurality of pixels two-dimensionally arranged and horizontal and vertical scanning circuits for reading the signal from the pixel array. Each scanning circuit comprises a plurality of unit stages cascaded, each unit stage comprising a plurality of first shift register units cascaded and a single second shift register unit which is associated with the plurality of first shift register units and which is driven by a clock different from the clock that drives the plurality of first shift register units. Each unit stage further comprises a first switch and a second switch. The input to the first unit of the first shift register units is also fed to the second shift register unit via the first switch. The output of the second shift register unit is fed to each of the plurality of first register units within the unit stage via the second switch. Each scanning circuit further comprises driving means for turning on/off the first and second switches in order to switch between a normal scanning and a thinned-out scanning.

A two-dimensional rangefinding sensor of the present invention consisting of an illuminating device for projecting light beams, which undergoes luminance modulation at a predetermined frequency for a predetermined duration with a predetermined cycle time, onto an object, an image-formation optical system for forming an image of the object illuminated with light beams which have undergone the luminance modulation and which have been projected from the illuminating device, a two-dimensional image sensor mounted on an image-formation plane of the image-formation optical system, a driving means for performing a modulation driving operation on an electrode terminal, which is operative to determine the sensitivity of the two-dimensional image sensor at the frequency, and a reading means for reading a signal corresponding to a signal charge generated in each of picture elements of the image sensors. Thereby, a range-data image of a three-dimensional object can be obtained by using a two-dimensional image sensor without mechanically scanning with illumination light.

A freon compressor comprises a compressor device and an electromotor device. The electromotor device is used for driving the compressor device and consists of a stator and a rotor rotating within the stator. The stator further consists of a stator core and stator windings wired on the stator core, and a three-phase sine alternating current waveform is applied to the stator windings. Therefore, the magnetic lines of force of the electromotor device are stabilized in space and time and noise is significantly reduced.

A solid-state image pickup device includes an array of rows and columns of pixels, a vertical scanning circuit having vertical scanning circuit units disposed to correspond to alternate pixel rows in the vertical direction, a horizontal scanning circuit for taking a pixel signal out of pixel rows being currently selected by the vertical scanning circuit, and selected-row changeover switch section consisting of a pair of first and second switches for transferring an output of one vertical scanning circuit unit to a preceding pixel row and a succeeding one of a certain row corresponding to this unit. A select signal is derived from the unit during two successive horizontal scanning periods, causing the first switch to turn on and the second one to turn off within a first horizontal scanning period, and also causing, during the following horizontal scanning period, the second switch to turn on and the first one to turn off. With such an arrangement, the vertical scanning circuit units are decreased in number to be half the pixel number in the vertical direction, thus enabling achievement of all-pixel independent sequential-scanning read scheme in the solid-state image pickup device.
