Abstract: A three-dimensional (3D) image display apparatus includes a display panel and a 3D image optical structure. The display panel has pixels arranged in an array and the pixels have a first region and a second region disposed adjacent to each other. The 3D image optical structure includes a plurality of first optical units disposed along a first direction. Each first optical unit has at least one first portion corresponding to the first region and at least one second portion corresponding to the second region. The first portion has a first curvature radius and a plurality of corresponding first circle centers, and the second portion has a second curvature radius and a plurality of corresponding second circle centers. The first curvature radius is different from the second curvature radius, and the first circle centers are not overlapped with the second circle centers in the vertical projection direction.

Abstract: An autostereoscopic display apparatus is provided. The autostereoscopic display apparatus includes a liquid-crystal panel and a barrier cell. The barrier cell includes a first substrate, a second substrate, and a liquid-crystal layer. The first substrate includes a first electrode. The second substrate includes a second electrode and a third electrode, wherein the second and third electrodes are separated from each other. The liquid-crystal layer is disposed between the first and second substrates. A black region between the first and third electrodes is formed when a first voltage is applied to the first and second electrodes and a second voltage is applied to the third electrode.

Abstract: A measuring device (1) is provided, comprising a measurement section (5) for measuring a specific constituent in a biological sample, an input accepting section (2) for accepting an input of an estimated value of subject's, measurement result, a coincidence degree determining section (61) for referencing data of an estimated value whose input is accepted at the input accepting section (2), and determining a degree of coincidence of a measured value obtained at the measurement section and the estimated value, and output sections (3, 4) for outputting a determined result obtained at the coincidence degree determining section (61).

Abstract: A motor control device carries cut feedback control of a motor such that the rotational speed of the motor is equal to the command speed. A control voltage is first calculated as the sum of a first constant times the difference between the command speed and the actual rotational speed, a second constant times the actual rotational speed and a predetermined offset value. The calculated control voltage is corrected on the basis of the phase difference between the command speed and the actual rotational speed and a voltage after the correction is outputted as a motor control voltage. The rotational speed of the motor can be caused to rapidly follow the target speed by adjusting the first and second constants and the offset value whether the command speed is relatively low or high, thereby to make it possible to control the motor at a constant speed.

Abstract: An error detecting unit for a rotational detector which outputs two kinds of pulse signals whose frequency according to rotation is equal and whose phase is different including counters for detecting whether or not either a rising or a falling edge of the two kinds of pulse signals appears alternately so as to detect an error of the corresponding rotational detector.

Abstract: A motor rotation control device furnished with a rotational detector for detecting the rotation of the motor and actual rotation direction detecting means for obtaining the actual direction of rotation of the corresponding motor on the basis of the rotation detection signals of the corresponding rotational detector and so composed that reverse drive force can be given to the corresponding motor by changing a commanding signal for appointing the direction of rotation of the corresponding motor when changing the direction of rotation of the corresponding motor or braking the motor, wherein any error of the motor rotation control device can be instantaneously detected, without waiting until the above actual direction of rotation of the motor becomes coincident with the rotation commanded direction after changeover, even right after the rotation commanded direction of motor by a commanding signal has been changed.
