摘要： An arithmetic device includes a first memory cell, a first bit line, a first transistor, a second memory cell, a second bit line, a second transistor, a third bit line, a first switching circuit, a second switching circuit and a controller. The controller sets a conduction state between the first memory cell and the first bit line by the first transistor, and sets a conduction state between the second memory cell and the second bit line by the second transistor. The controller sets the first switching circuit and the second switching circuit in a coupled state and sets the conduction state between the first bit line and the third bit line and between the second bit line and the third bit line to transition voltages of the first, second and third bit lines to a first voltage.

摘要： A method for testing an A/D converter with a built-in diagnostic circuit with a user supplied variable input voltage includes generating a charge by a binary-weighted capacitor array responsive to an external voltage and a user specified code. The method further includes applying the charge to a first input of a voltage comparator and applying a bias voltage to a second input of the voltage comparator, and generating, by the voltage comparator, a comparison voltage responsive to the applied charge and the bias voltage. The method also includes applying the comparison voltage to an input of a successive approximation register and generating, by the successive approximation register, an approximate digital code responsive to the comparison voltage. The method also includes determining if at least one bit of the approximate digital code fails to toggle independent of adjacent bits.

摘要： A method and device for the cyclic digital transfer of a position value of a moving object having inertial mass, the value range of the transferred position value being limited in such a way that no whole revolution or, in the case of a linear motion, other complete period that is conditional upon mechanical conditions is mappable, and the actual position is generated by detecting, in an evaluation unit, instances of the value range being exceeded.

摘要： An operating device for inputting the coordinate positions of a controlled object that moves across a screen. The present invention is directed to obviating the problems of the prior art involving the bad operability of a knob which requires rotation through a large angle to move the controlled object across the screen, and the short life-span of the knob due to frequent use. In order to overcome these problems, the rotational number of a main shaft is increased by a rotational number increasing mechanism and the rotational number of the output shaft of the rotational number increasing mechanism is optically or magnetically detected. The present invention is therefore suitable for use as an operating device for a TV game machine.

摘要： A shaft angle encoder comprises a code disc (21) mountable coaxially upon a rotary shaft (20) whose angular position is to be continuously measured. Coarse-bit angular position data are encoded digitally in Gray code by a pattern of opaque and transparent sectors provided on a plurality of inner annular tracks on the code disc (21). Fine-bit angular position data are encoded in analog triangular waveforms generated by the outermost annular track on the code disc (21). The analog position data are converted to fine-bit digital values, which are combined with coarse-bit digital values to obtain an angular position measurement. Alignment of the fine-bit digital values with the coarse-bit digital values obtained from the Gray code position data is accomplished by using information provided by overlapping the least significant bit of the coarse-bit digital values with the most significant bit of the fine-code digital values.

摘要： A sampling circuit in a successive approximation type analog-to-digital (A/D) converting device samples a pair of analog signals constituting a differential input signal. A capacitor circuit reflects a signal level of a reference signal in the pair of analog signals through an attenuation capacitance unit and a binary capacitance unit to generate a pair of voltage signals. A comparison circuit compares the pair of voltage signals. A control circuit determines a value of each bit of a digital signal on the basis of the result of the comparison and reflects the value in the reference signal. The attenuation capacitance unit includes a fixed capacitance unit connected between a signal node at which the sampled analog signals are held and a predetermined potential node and a variable capacitance unit connected between the signal node and the predetermined potential node in parallel with the fixed capacitance unit.
