  • Publication number: 20240066974
    Abstract: A vehicle battery cooling system that cools a battery built in an electrically powered vehicle includes a water storage tank, a circulating mechanism, a nozzle, a radiating fin, and a processor. The water storage tank is disposed inside the electrically powered vehicle and near the battery, and stores cooling water for cooling the battery. The circulating mechanism causes, when electric power is supplied from an external facility to the battery, the cooling water supplied from the external facility to circulate through the battery and the water storage tank. The nozzle injects the cooling water supplied from the circulating mechanism into a predetermined part of the electrically powered vehicle. The radiating fin is foldable and controls heat transfer between the battery and the water storage tank. The processor controls respective operations of the circulating mechanism and the nozzle, and switching between open and closed states of the radiating fin.

  • Publication number: 20230102961
    Abstract: It is an object to provide a water-absorbing resin that while maintaining water-absorbing resin physical properties such as water absorption performance, has a sufficiently reduced odor produced during swelling. The object is attained by causing the water-absorbing resin to be a water-absorbing resin which is a surface-crosslinked water-absorbing resin, the water-absorbing resin having a volatile component concentration of 3.5 ppm or less as measured when the water-absorbing resin is caused to stand still for 15 minutes under a condition that the water-absorbing resin has a swelling capacity of 1.0-fold.

  • Publication number: 20230050209
    Abstract: Provided is an absorbent body that, for example, in a case where the absorbent body has been used in an absorbent article, such as a thin disposable diaper, having an absorbent body with a low proportion of fiber material (hydrophilic fibers) such as pulp, enables the absorbent article such as a disposable diaper to have an improved liquid trapping function on second and subsequent urinations over the conventional ones and particularly to have an increased amount of liquid trapped under load on the second and subsequent urinations over the conventional ones. Also provided is a water-absorbing resin that is used in the absorbent body and has an increased absorption capacity under load on the second and subsequent urinations over the conventional ones. The absorbent body includes a water-absorbing resin having a gel expansion force under a load of 4.83 kPa of 26 N or more.

  • Patent number: 8436173
    Abstract: The present invention provides novel boron compounds which are useful, depending on their characteristics, as light-emitting materials, electron-transport materials, electron-injection materials, hole-blocking materials, or organic semiconductor materials, and which have new molecular structures quite different from those of the heretofore known boron compounds; their production processes; and functional electronic devices using the same. The novel boron compounds are, for example, those of the following formula (1): These boron compounds can be produced by, for example, reacting boron compounds of the following formula (4): with compounds of the following formula (5): in the presence of a catalyst containing at least one metal element selected from the group consisting of palladium, platinum, and nickel. These boron compounds are used for the functional electronic devices.

  • Publication number: 20040146042
    Abstract: In a mobile communication system including a home Mobile-IPv6 network for allocating a home address as a permanent address to a mobile node, a foreign Mobile-IPv6 network for allocating a care-of address to the mobile node, and at least one network including a stationary correspondent node not implementing Mobile-IPv6, a location supervising module stores the home address and said care-of address of the mobile node when the mobile node is away from the home Mobile-IPv6 network to the foreign Mobile-IPv6 network. An IP address translating module is provided for translation of an IP address between IPv6 and a protocol other than IPv6.

  • Patent number: 5406609
    Abstract: An X-ray analysis apparatus including an artificial multi-layered grating for rendering X-ray beams to be monochromatic before they are incident on a specimen to be analyzed. This artificial multi-layered grating operates to diffract the X-ray beam, generated from an X-ray radiation source and subsequently impinging on a reflective surface of the artificial multi-layered grating, at a predetermined angle of diffraction to provide the monochromatic X-ray beams. The periodicity of the spacing of lattice planes of the artificial multi-layered grating is so chosen as to be of a value progressively varying along the reflective surface thereof with an increase in distance from the X-ray radiation source. The X-ray analysis apparatus herein disclosed is designed to avoid any possible reduction of the intensity of the X-ray beams which would occur when they are rendered to be monochromatic, and to increase the intensity of the X-ray beams to ensure an improved accuracy in spectroscopic analysis.
