Abstract: A tire trouble detection device detects occurrence of a trouble in a tire. The tire trouble detection device comprises a detection unit which detects a change of state of a layered composition portion arranged in layers inside an outer sheath forming an outside surface of the tire, the layered composition portion forming a frame of the tire. A determination unit receives a result of the detection from the detection unit and determines occurrence of a trouble of the layered composition portion based on the received result of the detection.

Abstract: A vehicle-state obtaining apparatus, comprising (a) a sensing device including at least one sensor detecting a state of a vehicle and operable to transmit, by radio communication, sensor information including the vehicle state detected by the sensor, and (b) an information processing device operable to receive the sensor information and obtain the vehicle state on the basis of the received sensor information, wherein the information processing device obtains the vehicle state when it is recognized by one-way or two-way communication of key information between the information processing device and the sensing device that these two devices correspond to each other.

Abstract: A plurality of letter output devices (workstations, printers) are connected to a letter data control device by a transmission path. The control device stores letter data for transmission to the letter output devices, and is able to convert that letter data to a desired layout (e.g. from a vector font to a dot font) and then transmits the converted letter data to one or more of the letter output devices. The control device is able to select part of its stored letter data for transmission so that only commonly used letter data need be transmitted during start up of the system. Since a large amount of letter data may be stored in the control device, and only part may be transmitted to the letter output devices, those output devices can have a relatively small memory.

Abstract: A graphic processing device is composed of a main storage device, a drawing control device and a drawing device. The main storage device stores data relative to the coordinates of plural graphics. The drawing control device reads out the data relative to the coordinates of the plural graphics stored in the main storage device, scans the coordinate data to calculate the coordinates of intersecting points of a scanning line and the plural graphics for each position of the scanning line. The drawing control device also determines an overlapping area (AND area) or a common area (OR area) of the plural graphics on the basis of the coordinates of the intersecting points of the plural graphics and the scanning line. The drawing device draws the overlapping area (AND area) and the common area (OR area) of the plural graphics as a graphic.
