    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: 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: 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.
