  • Patent number: 9070485
    Abstract: In a reactor vessel (20) covered by cooling water (2), a tubular frame (10) with a bottom is hung within the cooling water (2) while still having an air environment in the interior, and the bottom section of the frame (10) is disposed within the reactor vessel (20), thereby achieving an air environment within the reactor vessel (20). Furthermore, since repairs to the reactor vessel (20) are performed by using the frame (10) while still having the air environment in the interior, this leads to the prevention of contamination and achieves improvements in working conditions such as preventing the generation of dust and reducing decontamination work. Accordingly, repairs can be performed in an air environment without draining the cooling water (2) within the reactor vessel (20), even in a state in which the reactor vessel (20) is covered by the cooling water (2).

  • Patent number: 7762367
    Abstract: A motorcycle that ensures engine cooling efficiency while suppressing radiator exposure has a head pipe and left and right downtubes extending downward from the head pipe. A radiator catches traveling wind from forwardly of the motorcycle. A louver provided on the radiator includes baffle plates that lead traveling wind to the radiator. The radiator has an overlapping portion between the downtubes that overlaps the downtubes as viewed from laterally of the motorcycle.

  • Patent number: 7484035
    Abstract: A microcomputer with built-in flash memory to which data can be written using a write clock signal, comprises a fixed oscillator circuit which outputs a clock signal of fixed frequency for generating the write clock signal. The flash memory is designed with a write-disturb time such that data loss does not occur when writing data with the write clock signal of fixed frequency.

  • Patent number: 7359475
    Abstract: A counter circuit includes a counter section having flip-flops of a plurality of stages. The flip-flops from a first stage to an (N-1)th (N is an integer more than 2) stage synchronously count a clock signal. A mask circuit section controls supply of the clock signal to the flip-flop of an N stage based on outputs of the flip-flops from the first stage to the (N-1)th stage.

  • Publication number: 20050005228
    Abstract: A Bluetooth module that corrects real-time data contains a synchronous connection-oriented link, a memory, and a signal correcting circuit. The signal correcting unit circuit receives packets of audio data from the synchronous connection-oriented link. When a failed packet has been determined, the signal correcting unit circuit determines the similarity between the data in the packets received before and after the failed packet and the data in two of the packets received before the failed packet with one packet therebetween to obtain two-packet data having similarity to the data in the packets received before and after the failed packet. The signal correcting unit circuit then interpolates the packet data between the obtained two-packet data in place of the data in the failed packet.

  • Publication number: 20040106378
    Abstract: An information communication apparatus includes a host computer and a BLUETOOTH module functioning as a communication module. A control unit of the BLUETOOTH module detects disconnection of a radio transmission link for a radio transmission signal and analyzes the reason for the disconnection. Then, the control unit determines whether or not to reconnect the disconnected radio transmission link on the basis of the analysis of the disconnection reason. If the disconnected radio transmission link should be reconnected, the control unit generates a reconnection command signal. In contrast, if the disconnected radio transmission link does not have to be reconnected, the control unit generates a forced link disconnection command signal.

  • Patent number: 6415225
    Abstract: A system for executing guidance to a destination properly even if the destination is connected to a non-guidance target road, such as a small street. The system has a judgment device for determining whether a road connecting to a destination on the searched route is a non-guidance target road, a controller for determining a guidance terminating point on the basis of the determinative result of the judgment device, wherein if a road connecting to a destination is a non-guidance target road as determined by the judgment device, then the last intersection point of the guidance target road to the non-guidance target road or a road end closest to the departure side of the non-guidance target road is determined as a guidance terminating point.

  • Patent number: 5952791
    Abstract: Abnormal states in a high-voltage cable connected to a backlight of a liquid crystal display are detected. This invention includes: a secondary winding of a transformer; a discharge tube connected to the secondary winding of the transformer; means connected to the discharge tube for detecting a tube current; means connected to the secondary winding of the transformer for detecting a transformer current; and abnormal-state detection means for comparing a value of the tube current detected by the tube current detection means with a value of the transformer current detected by the transformer current detection means and interrupting a power supply if a difference greater than a predetermined value is detected. Thus, a case of lighting delayed due to the darkness effect can also be dealt with.

  • Patent number: 5537296
    Abstract: A lamp guarding unit 26 of a backlight 20 for a liquid crystal display is detachable from a lamp holding unit 24 fixed to a light-guiding plate 22 in a direction perpendicular to a light illumination surface of the light-guiding plate 22. Therefore, in replacing a fluorescent tube 44, it is not necessary to replace the whole backlight 20 or for the user to touch the fluorescent tube 44, which is difficult to handle. Because of the perpendicular removal, only a small space is needed for the replacement. Thus, the fluorescent tube 44 can be replaced safely and easily, and only a small space is required for this replacement.
