  • Publication number: 20130063154
    Abstract: [Problem to be Solved] To prevent false determination of a fuse blowout with a fuse not blown by certainly detecting the fuse blowout. [Solution] A power supply apparatus includes: a drive battery (1) having a plurality of battery units (2) connected in series; a fuse (19) connected in series with the drive battery (1); a voltage detection circuit (3) detecting a voltage of the battery unit (2) by dividing the voltage at a resistance voltage dividing circuit (11) with a line connected to one end of the fuse (19) as a ground line; and a blowout detection circuit (4) detecting a blowout of the fuse (19) based on the voltage detected at the voltage detection circuit (3). The blowout detection circuit (4) determines that the fuse is blown when a detected voltage of the battery unit (2) connected to a fuse (19) side with respect to the ground line falls within an abnormal range.

  • Patent number: 7561301
    Abstract: A printing system is designed to reduce the overall time and the cost required for printing patterns on objects such as musical instruments and prevents printed patterns from being partially extended or distorted. Image data representing prescribed patterns are processed in response to object form data representing the form of an object, wherein upon receipt of a user's print instruction, an RGB color inkjet printer ejects ink onto a prescribed surface of the object on the basis of the processed image data. Image data can be produced by picking up an image of another surface of the object, which is transferred onto the prescribed surface of the object, thus establishing a sense of unity in visual sensation therebetween. Alternatively, image data can be processed in correspondence with the selected surface of the object, so that the prescribed image is printed on the selected surface of the object.

  • Patent number: 7558584
    Abstract: Menu data supplied from an IP server 500 to a mobile station 101 is embedded with a location information substitution data string “NULLAREA” together with a URL of a particular IP server 500. The mobile station 101, upon detection of the location information substitution data string from a menu data selected by the user, determines whether location information can be transmitted to the IP server 500. In the case where the determination is that the transmission is permitted, the mobile station 101 detects its location information and, after substituting the location information for the location information substitution data string, transmits the data to the IP server 500.
