摘要:
A semiconductor integrated circuit device such as a memory device with logic function comprises a plurality of RAM macrocells and gate arrays. The RAM macrocells are constituted by bipolar CMOS RAMs having a total memory capacity of at least 100 kilobits, and the gate arrays contain at least 4000 gates. The logic circuits in the memory device with logic function or the like are constructed by selectively combining CMOS, bipolar CMOS or ECL gate circuits depending on the output load capacity, transmission characteristic requirement, power dissipation and required layout area. The level of signals at various circuits is set to the ECL level or MOS level depending on the local circuit configuration and other factors. The memory device further incorporates sequence control circuits required to be installed downstream of buffer storages of computers.

A digital-to-analog converter (DAC) converts digital input data into an analog output signal with less harmonic distortion over an entire signal-level range. An exponent value detector detects from the digital input data the number of bits by which the digital input data is to be shifted to form a mantissa part thereof. A digital shifter shifts the digital input data in accordance with the output of the exponent value detector, and outputs the mantissa part which is then supplied to a mantissa-part DAC. The mantissa-part DAC comprises an R-2R resistor ladder network and outputs the result of DA conversion of the mantissa part to an exponent-part DAC. The exponent DAC shifts the output of the mantissa-part DAC by an amount determined by the output of the exponent value detector, and outputs the shifted signal as the analog output signal of this DAC. A control circuit is provided between the digital shifter and the mantissa-part DAC, which prevents, in accordance with the output of the exponent value detector, the least significant bits of the mantissa-part DAC from operatively functioning to thereby decrease the number of operable bits thereof when the magnitude of the digital input data is small.

Systems and methods for correcting a location of a terminal are provided. In various aspects, a processor in a position correction apparatus may associate a reference position with the terminal, and determine a range for the terminal based on the reference position. The processor may also associate a second position with the terminal, and determine if the second position associated with the terminal is outside the determined range for the terminal based on the reference position. Upon a determination that indicates that the second position is outside the determined range, the processor may correct the second position to a corrected position associated with the terminal.

Systems and methods for correcting a location of a terminal are provided. A processor in a position correction apparatus may select an action label from a plurality of action labels, and may associate the selected action label with the terminal. In various aspects, the selected action label may be selected by the processor based on a movement of the terminal. The processor may further select a correction algorithm for correcting the position of the terminal, where the selected correction algorithm may be selected from one or more correction algorithms that are associated with the selected action label. The processor may then correct the position of the terminal to a corrected position of the terminal using the selected correction algorithm.

A pressure sensor and a pressure measuring device are provided applicable to a variety of pressure detection targets and capable of measuring a surface pressure. The pressure sensor is configured by laminating a metal layer made of a metal film, an elastic member layer made of a non-metal material, and a coil layer including an exciting coil. Also, as for a sensor sheet on which sensors that each measure point pressure are arranged in an array, variable elements of the elastic member layer and the coil layer are appropriately changed, thereby forming sensors with a single sheet that are different in pressure detection accuracy or pressure detection range for predetermined areas. Also provided is a pressure measuring device that controls exciting timing or frequency of applied voltage of each exciting coil on a sensor sheet.

摘要:
In a lens mounting mechanism, by rotating a ring member through touching lugs of the ring member and aligning grooves of a base member and recesses of the ring member in the circumferential direction, and then inserting a lens barrel into a hole portion, the lens barrel is moved to the hole portion without being interfered by projections of a barrel mounting member, so that the lens barrel can be inserted into the hole portion until a flange portion abuts against an opening end surface. Then, by touching the lugs of the ring member and rotating the ring member to displace the recesses from the grooves of the base member in the circumference direction, the projection of the barrel mounting member is locked by the ring member and the barrel mounting member is fixed to the base member, so that the lens barrel can be mounted to the apparatus body.
