  • Publication number: 20120325440
    Abstract: There is provided a cooling device not affected by gravity by exerting a strong capillary attraction to be hard to deteriorate in transportation function. Unidirectionally-aligned copper fiber assembly 8 is mounted, by a sintering process, on an inner wall of a heat pipe 3 along the longitudinal direction of the heat pipe 3. Therefore, by a strong capillary attraction caused by fine copper fiber assembly 8, purified water can be transported without being affected by gravity. A flow volume just enough for the purified water to be prevented from drying out by its evaporation can be maintained, thus making it hard for a function in the transportation of the purified water to be deactivated. Further, the unidirectionally-aligned copper fiber assembly 8 is mounted along the longitudinal direction of heat pipe 3 and hence the purified water smoothly flows in the longitudinal direction of heat pipe 3.

  • Patent number: 8185159
    Abstract: A wireless communication system including a wireless terminal, a plurality of base stations and a call processing control unit is disclosed. The wireless terminal, upon reception of the notification information from any of the base stations, judges whether the area included in the notification information is contained in the location registration area list stored in a storage unit, and in the case where the particular area is not so contained, sends a location registration request to the call processing control unit. On the other hand, the call processing control unit creates a new location registration area list based on the area included in the notification information and the neighboring areas, and sends the location registration area list to the wireless terminal thereby to execute the paging process.

  • Publication number: 20110271336
    Abstract: A CPU 11 executes a management program B (Pb), from a management program A (Pa) receives authentication information, a request, and a program ID, and determines whether the authentication information is correct. If the authentication information is correct, the CPU 11 acquires the execution authority information of the authenticated user, compares the received program ID with the program ID including in the acquired execution authority information, and determines whether execution authority corresponding to the received program ID is defined. If the CPU 11 determines that execution authority corresponding to the received program ID is defined, it established the defined execution authority as the execution authority for the management program B (Pb).

  • Patent number: 7114516
    Abstract: One object of the present invention is to monitor water pipes regularly and to detect water leaks by using basic equipment and to provide a device that generates an alarm when a leak occurs. The present invention responds not only to minor leaks that occur naturally because, for instance, a water pipe is decrepit, but also responds to human-caused leaks, such as those that occur because a person forgets to turn off a water faucet or because of the failure of equipment such as a hot-water heater. The present invention is a leak-detection alarm system that is composed of two main parts: (1) a leak-detecting check valve that detects movements of a movable device that makes the same movement as the valve element of a check valve that is attached to a water pipe and performs switching, and that transmits as detection signals the movement of valve elements, and (2) a signal-processing device that analyzes detection signals transmitted by the leak-detecting check valve and actuates a leak-detection alarm.

  • Patent number: 6466522
    Abstract: An indicating plate for a solar watch, comprising a color diffusion plate which, by virtue of the presence of a coloring agent, a coloring light diffusing agent, a colored translucent substrate, a pattern layer/colored thin film layer and a diffusion layer, is adapted to transmit a portion of light having a wavelength within a range capable of causing a solar cell housed under the indicating plate to generate power. The color diffusion plate is adapted to make it difficult to view the solar cell from the outside through the indicating plate and is also adapted to impart a color tone to the indicating plate.

  • Patent number: 6435605
    Abstract: A vehicle sunroof has a tilting lid provided at a front part of an opening formed in a roof of a vehicle. The tilting lid is adapted to be moved vertically at a rear end thereof with lifter mechanisms. A sliding lid is provided at a rear part of the opening supported by sliders adapted to be moved along guide rails disposed on both side edge portions of the opening and is constructed so as to be moved longitudinally through such movements of the sliders. The lifter mechanisms are provided in such a manner as to be oriented laterally at portions facing a rear end of the tilting lid on a laterally oriented cross member disposed so as to extend between front end portions of the left and right guide rails.
