  • Patent number: 9285528
    Abstract: Disclosed herein is an edge-type lighting device which is configured such that when a light guide plate thermally expands, a light source is prevented from being pressed. In the lighting device according to the present invention, a light guide plate (2) is slidably supported so that the light guide plate (2) can expand in the planar direction, and a light source (3) disposed on an edge of the light guide plate (2) is movably supported in the same direction. A light-guide-plate stopper (4b) is disposed at a position facing an edge (2A) of the light guide plate (2) to prevent the light guide plate (2) from expanding excessively. Thus, the light source (3) can be prevented from being pressed toward a frame member (4).

  • Patent number: 8858054
    Abstract: The present invention relates to an edge-type lighting device using an LED light source which has high light-emitting efficiency regardless of thermal expansion of a light guide plate. An LED light source (3) is disposed on an edge of a light guide plate (2) so as to be movable in the normal line direction (±n) of the edge (2c) of the light guide plate. A slide member (7) is slidably disposed on the rear surface of the LED light source. A spring (8) is disposed in a frame member (4) on the rear surface of the slide member. Thus, the LED light source can always be pressed toward the edge of the light guide plate regardless of the thermal expansion of the light guide plate. Because the spring has a simple structure, the lighting device can be compact compared to the case where a coil spring is used.

  • Patent number: 6982990
    Abstract: A CPU controls the storage of isochronous packets into a main memory. The CPU inserts a nullpacket, which will be ignored by a reception apparatus, into isochronous packets so that the isochronous packets have the same size. A 1394 DMA controller controls the transmission of stored isochronous packets, which have the same size due to the inserted nullpacket, over a 1394 bus.

  • Patent number: 5939861
    Abstract: Charging and discharging of a battery are controlled while observing the state of the battery, thereby improving its efficiency and increasing battery service life. A program control circuit acquires vehicle speed from a vehicle speed sensor and the rotational speed of the internal combustion engine from a rotation sensor. The program control circuit controls an inverter which performs AC-to-DC or DC-to-AC conversion between a motor-generator coupled to the internal combustion engine and a battery mounted on the vehicle. At the same time, the program control circuit acquires the charging and discharging current (i) of the battery, which is detected by a current sensor, and calculates the time integral I of the charging and discharging current (i). The circuit controls the charging current to the battery during regenerative braking, and the discharge current when the vehicle is being driven, in accordance with a function of the time integral I.

  • Patent number: 4222849
    Abstract: Liquefaction of coal is realized in a chemical manner without employing high temperature and high pressure, only by such a process, wherein granulated coal is first soaked in aqueous solution of caustic soda and subsequently pulverized after it is taken out and dried, and then, the so obtained coal powder is mixed with an aqueous solution containing sodium hydroxide and organic carboxylic acid by agitation, thereafter the mixture is kept still for sufficient time until the coal becomes ominous of liquefaction, and finally, the mixture is heated at a temperature from 90.degree. to 150.degree. C. with further addition of water.
