    摘要: In the comparator circuit, the amplifier circuit is comprised of an inverting amplifier section having a high gain and a noninverting amplifier section having a low output impedance. Therefore, the comparator circuit has a high input sensitivity. The comparator circuit can also operate at a high speed.

    摘要: A successive approximation type A/D converter of the present invention has a capacitor having a predetermined capacitance value and arranged between an input terminal of a voltage comparator and a fixed potential terminal having a predetermined potential. According to the successive approximation type A/D converter of the present invention, the capacitor arranged between the input terminal of the voltage comparator and the fixed potential terminal having the predetermined potential prevents a potential at the input node of the voltage comparator from being greatly changed to exceed a power source voltage range due the influences of a local D/A converter when the sample mode is switched to the approximation mode. Therefore, the leakage of charges stored in the input side of the voltage comparator can be prevented. Accordingly, even if the amplitude of an analog input voltage is equal to the amplitude of the power source voltage, high-precision A/D conversion can still be performed.

    摘要: The cables are configured to supply electric power from an inverter to a motor. The cables include a connector and plural terminals fixed to the connector. A housing of the connector includes a first rib, provided between the adjacent terminals, connecting mutually facing surfaces of the housing. The terminal block is attached to an enclosure of the inverter or motor. The terminal block includes plural retaining walls, each of which encloses and retains a nut. The terminal block includes a second rib connecting adjacent retaining walls. One of the first and second ribs includes a recess. The connector is connected to the terminal block when each of the terminals is fastened to the terminal block with a bolt and the nut. The other of the first and second ribs is disposed in the recess and the ribs intersect when the connector is connected to the terminal block.

    摘要: A high-frequency power amplifier of the type to be mounted in an RF module for mobile phones having high-frequency power field effect transistors and gate protective diodes which are coupled between the gates and the sources of the high-frequency power field effect transistors. The gate protective diodes have an n type region formed over the main surface of a p type epitaxial layer, a first p type region formed at the center of the main surface of the n type region, a second p type region formed over the main surface of the epitaxial layer around the n type region from the periphery of the main surface of the n type region, and p+ type buried layers for coupling the second p type region to a substrate body. The distance between the end portions of the p+ type buried layers and the n+ type region is 7 μm or more.

    摘要: An ultrasonic injection mold for an optical disk includes a movable die and a fixed die; a disk molding cavity formed between the movable die and the fixed die; a stamper positioned at the bottom of the cavity for forming a pit on a surface of the disk; and an ultrasonic generation device provided on the movable die or fixed die for applying ultrasonic waves to the cavity in performing infection molding. One or more slits are formed on the movable die and the fixed die in the direction which crosses the radial direction of the cavity. The ultrasonic injection mold minimizes the amplitude of the ultrasonic transmitted in the radial direction of the cavity.

    摘要: A toner mark which is to be sensed by a toner concentration sensor in an electrophotographic printing apparatus includes a rectangular dot pattern where a plurality of toner dot patterns are spaced in a staggered configuration. Each of the toner dot patterns is formed in line which is angled with respect to a width direction of the toner mark. Further, any line along a width direction of the toner mark crosses at least one toner dot pattern.
