  • Patent number: 10703951
    Abstract: Disclosed is a heat transport medium to be transported with a fluid that is liquid in an operating temperature range containing a porous material and a latent heat storage material penetrated in the pores of the porous material, wherein the latent heat storage material is incompatible with the fluid and has a melting point within the operating temperature range, and the porous material has a liquid repellency to the fluid, an affinity for the latent heat storage material, and a sponge hardness of not more than 50. This invention achieves stable heat transport with a high heat conversion efficiency even by circulating the medium through a pipeline over a long period of time.

  • Publication number: 20160280744
    Abstract: The purpose of the present invention is to provide a novel protein, which have such excellent pH responsiveness that the antibody binding property to the Fc region of the immunoglobulin in the neutral region is improved and the binding property to the Fc region of the immunoglobulin in the weakly acidic region is much decreased when compared to the wild-type proteins such as protein G and protein A that have affinity for the protein comprising the Fc region of the immunoglobulin G (IgG), and a mutant-type protein (an improved protein) comprising their domain mutant. The present invention relates to a protein constituted by linking plural domains having affinity for a protein comprising the Fc region of the immunoglobulin G (IgG) with linkers, wherein an extended length to the maximum of the linker is 80-240 angstrom.

  • Patent number: 5850213
    Abstract: A three-dimensional image special effect apparatus wherein the motion of an image across a display screen is controlled by a track ball and rotary ring.

  • Patent number: 5714982
    Abstract: A three-dimensional image special effect apparatus wherein operation for setting a parameter can be performed simply and a special image can be moved smoothly to a distance only by a single manual operation of a track ball or a rotary ring is disclosed. A special image produced by an image special effect processing section is manually operated in first and second three-dimensional directions by a track ball and in a third three-dimensional direction by a rotary ring disposed along an outer periphery of the track ball. A condition in which a parameter for determining a condition of the special image can be set is established and a setting menu for setting a parameter which determines a condition of the special image is produced by a CPU. Under the control of the CPU, a cursor for designating a parameter on the setting menu is operated by way of the track ball, and a value of the parameter is set by way of the rotary ring.

  • Patent number: 5583648
    Abstract: Whether or not a luminance signal or an HD input signal is input to a picture signal recording apparatus is detected, and a recording mode is determined according to the detection of the luminance signal in a recording mode determining unit. In cases where the luminance signal is detected, first and second color difference signals of the HD input signal are alternately deleted on every scanning line. Thereafter, the luminance signal pertaining to odd-numbered scanning lines and the first color difference signal are time-compressed and multiplexed on every scanning line, and the luminance signal pertaining to even-numbered scanning lines and the second color difference signal are time-compressed and multiplexed on every scanning line. In contrast, in cases where the luminance signal is not detected, a luminance signal and first and second color difference signals of a normal picture signal input to the apparatus are time-compressed and multiplexed on every scanning line.
