摘要:
In a parallel adder circuit, first and second full adders each having an addend input terminal, an augend input terminal, a sum output terminal, a carry input terminal, and a carry output terminal are alternately connected such that the carry output terminal of the preceding full adder is directly connected to the carry input terminal of the succeeding full adder. In order to shorten the carry propagation delay time, the first full adder is arranged to receive an inverted carry signal (FALSE) from the preceding stage and to provide a carry signal (TRUE) to the succeeding stage, while the second full adder is arranged to receive a carry signal (TRUE) from the preceding stage and to provide an inverted carry signal (FALSE) to the succeeding stage.
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.

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.

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.

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.
摘要:
An image reading apparatus which reads document surfaces of open book-like documents placed on a document platen in a face upward condition and detects height of the document to control an image reading operation. An image reader reads the document platen on which the document is placed and outputs image data. A height detector detects height distribution of the document, and a discrimination device determines whether or not abnormalities occur in the height distribution of the document. A memory stores the height distribution of the document, and a update device updates the height distribution of the document stored in the memory when the abnormalities do not occur in the height distribution of the document. A correcting device corrects distortion of the image data caused by the height of the document in accordance with the height distribution of the document stored in the memory.
