摘要:
An image reading apparatus includes one or more sliders which carry optical parts and can linearly reciprocate in a predetermined direction. The apparatus optically scans and thereby reads an image on an original document located at a predetermined position. The image reading apparatus includes a magnetic encoder for detecting positions of the sliders.

It is an object of the present invention to provide a repair address analysis system for a semiconductor test which can effect repair of a memory device from fails in a short time even when a fail is produced on a repair line. Fail count means effects counting of fail bits for an address value of a memory device and counting of fail bits of an address value of a repair line simultaneously with each other, and information of the repair line is replaced into the counted address.

A printing medium feeding device for an image reproduction apparatus has a feed roller driveable in forward and reverse directions. A pinch roller is rotatably supported by a pivotable arm and rotatably supports a hook. The hook is effective when in an engaged position to hook onto a feed roller shaft so as to position the pinch roller and feed roller to sandwich therebetween a printing medium. The pinch roller is rotated by the rotation of the feed roller. An actuating plate carrying a one-way transmission is rotatable by the shaft of the pinch roller only when the feed roller is driven in the reverse direction. The actuating plate moves the hook to release the engagement with the feed roller shaft to release the pinching of the printing medium between the pinch roller and the feed roller at appropriate times, such as during printing.

A stored instructions executing type timing signal generating system for flexibly generating a plurality of control timing signals having many changing points includes an instruction memory for storing a series of instructions stating contents of changes and relative time intervals between the changes of a series of control timing signals and a circuit for triggering the instruction execution by the absolute time for the series of instructions, so that after a first instruction has been executed, each succeeding instruction is sequentially executed on the basis of a relative time interval before the execution of a next instruction stated in the instructions, thereby to generate the control timing signals. The number of changing points of the control timing signals is basically dependent only on the number of words of the instruction memory, and therefore the plurality of control timing signals having many changing points can be generated easily.

A rotary type electrostatic spray painting device is provided with a rotary shaft and a spray head fixed onto the front end of the rotary shaft. Paint is fed onto the cup-shaped inner wall of the spray head. The rotary shaft is supported in a no-contact state by a single thrust air bearing, a pair of radial air bearings, and a magnetic bearing arranged between the radial air bearings. An electrode for providing continuous electrical contact with the rear end of the rotary shaft, is cooled by being at least partially arranged in a flow path of compressed air. A negative high voltage is applied to the housing of the painting device, which is applied to the spray head via the electrode and the rotary shaft.

A rotary type electrostatic spray painting device is provided with a metallic rotary shaft and a spray head fixed onto the front end of the metallic rotary shaft. Paint is fed onto a cup shaped inner wall of the spray head. The metallic rotary shaft is supported by a single thrust air bearing and a pair of radial air bearings. An electrode continuously contacts the rear end of the metallic rotary shaft. A negative high voltage is applied to the housing of the paint device. In addition, the negative high voltage is also applied to the spray head via the electrode and the metallic rotary shaft. The thrust air bearing comprises an annular plate fixed onto the housing, and a pair of runners fixed onto the metallic rotary shaft and arranged on each side of the annular plate. A plurality of radially extending air passages is formed in the annular plate. A plurality of air outflow bores is formed on the side walls of the annular plate. Each of the air outflow bores is connected to an inlet for receiving compressed air via the corresponding air passage.

Each of the radial air bearings comprises a plurality of pads cooperating with the rotary shaft, and a bearing support frame supporting the pads via support pins. The bearing support frame is mounted on the outer wall of the housing via O rings. The bearing support frame and the housing are interconnected to each other by a bolt for preventing relative rotation therebetween.

An information processing apparatus may be implemented as a route navigator, which uses a route navigation method and a computer program product. A processing circuit is used to calculate respective passage frequencies of passageway segments in a passage history. The processing circuit then selects a navigation route to a destination, includes at least one passageway segment with a passage frequency that is a low or zero passage frequency.

A geomagnetic sensor includes: a core that constitutes a closed magnetic circuit; a pair of coils that are wound around the core in positions facing each other and are connected in series to generate magnetic flux in the same circumferential direction in the core; an excitation power supply that applies an alternating current with a superimposed direct current to the pair of coils; and a detection circuit that is connected to a connection point of the pair of coils. Unlike a conventional flux gate type geomagnetic sensor, it is not required to excite the core until the core is magnetically saturated, and it is therefore possible to reduce power consumption.
