Patent number: 10140933Abstract: According to an aspect, a display apparatus includes: a plurality of light sources; a display device irradiated with light from the light sources; and a controller. The display area includes a plurality of partial areas corresponding to the light sources on a one-to-one basis. Each of the partial areas includes a first area and a second area, the first area being irradiated with light from a first light source that corresponds thereto, and the second area being irradiated with light from the first light source and a second light source adjacent to the first light source. The controller controls an operation of the first light source based on whether the first area requires the light from the first light source and whether the second area obtains light required for display output by receiving the light from the second light source.Type: GrantFiled: April 25, 2017Date of Patent: November 27, 2018Assignee: Japan Display Inc.Inventors: Kazuhiko Sako, Naoyuki Takasaki, Tsutomu Harada, Tatsuya Yata, Shigenori Aoki

Patent number: 9455212Abstract: A loop heat pipe system includes a loop heat pipe (LHP), a temperature sensor, a heater and a controller. The temperature sensor measures temperature of a working fluid portion of the LHP in which the working fluid has different phases depending on whether or not the LHP is in a disable status not to start up a heat transportation, in which a liquid phase of the working fluid does not exist in an evaporator of the LHP. The heater heats a heating target part of a vapor line. The controller, in order to start up the LHP, turns on the heater, monitors temperature of the heating target part using the temperature sensor, and turns off the heater when detecting a change in the monitored temperature, caused by condensation of a vapor phase of the working fluid.Type: GrantFiled: May 17, 2012Date of Patent: September 27, 2016Assignee: FUJITSU LIMITEDInventors: Hiroki Uchida, Takeshi Shioga, Shigenori Aoki, Susumu Ogata, Hideaki Nagaoka
