摘要： A touch panel input device is provide with a panel capable of propagating surface acoustic waves and in which surface acoustic wave attenuation is caused by a object in contact with said panel. An emission circuit outputs a surface acoustic wave drive; and an emission transducer emits surface acoustic waves in the panel in accordance with the surface wave drive outputted from said emission circuit. A reception transducer receives surface acoustic waves in the panel and outputs a received acoustic signal. A reception circuit receives the received acoustic wave signal from the reception transducer to detect a position at which the received acoustic wave is attenuated as indicative of a position that the object contacts the panel. A controller controls the emission circuit and the reception circuit, and comprises a processor for computing a width of the contact by the object on the panel in accordance with a waveform detected by the reception circuit. A judging circuit distinguishes a type of object in contact based on the width obtained by the processor.

摘要： An image signal processing circuit (102) includes a phase-expansion circuit (103), a digital polarity-inversion circuit (104), first to sixth D/A converters (111 to 116), and first to sixth operational amplifiers (151 to 156). The resistance value of the first to sixth amplitude adjusting resistors (121 to 126) which cause the output amplitude of an analog signal output from the first to sixth D/A converters (111 to 116) to be fixed is adjusted by laser trimming. First to sixth gain setting resistors (161 to 166) are connected to the first to sixth operational amplifiers (151 to 156). The first gain setting resistor (161) includes a first resistor (131) and a second resistor (141), and the gain of the operational amplifier (151) is set by the resistance ratio (R2/R1) thereof. In order that this resistance ratio (R2/R1) is fixed for each set, the first resistor (131) and the second resistor (141) are formed on the same substrate by undergoing the same manufacturing process. As a result, there is no need to use the first and second resistors (131, 141) for variable resistors.

摘要： Image data to which gamma correction for a CRT has been applied is digitally gamma corrected to image data based on an applied voltage-transmittance characteristic of a liquid crystal display unit.A digital gamma correction circuit for correcting digital image data to which gamma correction for a CRT has been applied to digital image data suitable for driving display on liquid crystal display units 50R, 50G, 50B comprises a first digital gamma correction circuit 24 and a second digital gamma correction circuit 32. The first digital gamma correction circuit 24 applies a first gamma correction containing a correction for effectively restoring digital image data to which gamma correction for a CRT has been applied to the digital image data before gamma correction for a CRT was applied. The second digital gamma correction circuit 32 applies a second gamma correction based on an applied voltage-transmittance characteristic of the liquid crystal display unit to the digital image data before or after the first gamma correction is applied.

摘要： A disk drive includes media for recording data, disk heads for recording data and reproducing data on the disks. The heads are supported on arms. A head actuator drives the arms moving the head to a predetermined data recording track on the disk. A spindle motor rotates the disk at a predetermined rotating speed. The spindle motor includes a rotor magnet disposed within a stator coil. The disk head and actuator motor are mounted on a pivot on opposed sides of each other. To control head positioning, first positioning data for positioning the disk heads and second positioning data are provided on each data surface. This data is detected by a data head. Second positioning data may be positioned on tracks not used for containing data. The head position is compensated by the stored second positioning information superimposed on the first positioning data.
