    摘要: A magnetic detecting circuit has a magneto resistance element which converts a change of magnetism detected into a signal. A plurality of these magneto resistive elements are provided on a plane, and are oriented on the plane in two opposite directions having angles, relative to a bias direction, having substantially equal absolute values. The placement in opposite directions allows the resistance values from the elements to change in approximately the same direction as the object moves, to allow a monotonic change in the bias magnetic field. The change of the bias magnetic field can be detected from the change of resistance values of the magneto resistive elements.

    摘要: A pulse phase difference encoding circuit provides a digital signal indicating a phase difference between a first input pulse and a second input pulse. The first input pulse is provided to and circulated in a ring signal delay circuit having a plurality of signal delay elements that are connected in series. Intermediate points between the delay elements provide delayed pulses having different delay times. Upon receiving the second input pulse, a selector selects one delay pulse provided by the delay element at which the first input pulse has arrived, and generates a digital positional signal indicating a position of the selected delay element. The number of rounds of circulation of the first input pulse in the ring signal delay circuit is separately counted. According to the number of rounds of circulation of the first pulse and the positional signal, the digital signal indicating the phase difference between the first and second input pulses is formed.

    摘要: A Group III and V element compound semiconductor such as gallium arsenide is formed on a semiconductor wafer by so-called MOCVD. A first pair of convex portions, a second pair of convex portions and crossing portion are formed from such compound semiconductor by an etching using a predetermined etching substance so that one convex portion of each pair is opposite to the other convex portion thereof and that a same crystalline surface of the crossing portion is exposed at all points where the first pair of convex portions crosses the second pair of convex portions. A pair of input terminals and a pair of output terminals are electrically connected to each convex portion of the first pair and the second pair, respectively so as to input electric current to each convex portion of the first pair and to output voltage generated in response to a magnetic field strength in such compound semiconductor. Accordingly, the occurrence of the unbalanced voltage is prevented because of the geometrical balance of two pair convex portions and crossing portion.

    摘要: An imaging device (1) includes an all-pixel readout imaging element (2) outputting a LONG signal and a SHORT signal in one field period for each pixel line, a mixing level calculator (7) calculating for each pixel line a mixing level at which the luminance level of the LONG signal is saturated, and an offset calculator (8) calculating for each pixel line an offset that raises the luminance level of the SHORT signal to the mixing level. Level mixing means (9) generates a level mixed signal for each pixel line so as to obtain a LONG signal when the luminance level is lower than the mixing level and obtain a SHORT signal with the offset added when the luminance level is higher than the mixing level. Consequently, an image having a wide dynamic range and a high resolution can be obtained and line-to-line luminance differences in the obtained image can be suppressed.
