Patent number: 11306237Abstract: A latent-heat storage material composition includes: a latent-heat storage material for storing or releasing heat by utilizing absorption or release of latent heat in association with phase change; and additives mixed with the latent-heat storage material. The additives can adjust a property of the latent-heat storage material. The additives include a first additive, which is a water-soluble substance belonging to polysaccharides and is gellan gum, which is also a thickener for increasing the viscosity of a melt of the latent-heat storage material composition in a liquid phase state, based on interaction of the thickener with water contained in the latent-heat storage material composition and cations. The content of the gellan gum is 1 wt % or less of the weight of the whole latent-heat storage material composition.Type: GrantFiled: February 19, 2018Date of Patent: April 19, 2022Assignee: TOHO GAS CO., LTD.Inventors: Kohei Nakamura, Takashi Ina

Patent number: 7648516Abstract: A medical knife has a cutting edge formed along the outer edge of a blade portion, and the thickness of the lower portion located under a boundary acting as a surface including the cutting edge is made thinner than that of an upper portion located on the boundary, or a lower surface is composed of the surface including the cutting edge. The surface of the upper portion on the above surface including the cutting edge is composed of a first slanting surface constituting the cutting edge, a second reflecting surface, and a flat surface composed of a non-reflecting surface as well as the lower portion has a lower slanting surface 10 and a lower flat surface 11 each composed of a reflecting surface. With the above arrangement, the medical knife can reduce the amount of reflected light when an operation such as an ophthalmic operation is executed under a microscope.Type: GrantFiled: June 24, 2004Date of Patent: January 19, 2010Assignee: Mani, Inc.Inventors: Kanji Matsutani, Takashi Ina, Masahiko Saito, Takayuki Matsumoto

Patent number: 7458494Abstract: A surgical stapler has a body capable of containing a plurality of staples in an aligned state; a ram provided inside the body, having a central concave portion and pressure armatures on both sides of the concave portion; an anvil that, when the armatures of the ram contact both sides of a crown of a staple, forces the center of the crown into the concave portion of the ram; and a trigger rotatably supported on the body so as to cause relative movement between the ram and the anvil. The trigger as a moving member and the body as another member strike each other so as to produce a sound and/or a vibration indicating that a staple sandwiched between the ram and the anvil is bent by the advance of the anvil into the concave portion of the ram and bending of the staple is completed.Type: GrantFiled: February 21, 2006Date of Patent: December 2, 2008Assignee: MANI, Inc.Inventors: Kanji Matsutani, Masatoshi Fukuda, Toshiharu Kamei, Takashi Ina

Patent number: 7356898Abstract: A method for producing a surgical knife of a very small size for use in ophthalmic surgery under a microscopic environment having a sharp edge without causing reflection of lights. The surgical knife comprises a handle, and a blade attached to the handle. The blade has a sharp polished cutting edge, a rough machined surface provided inside of the cutting edge having a relatively rough surface area, and an inner flat area. An anti-reflection treatment is provided on an upper and lower surfaces of the blade except for the cutting edge, thereby prohibiting reflection or emission of lights from the knife.Type: GrantFiled: May 16, 2003Date of Patent: April 15, 2008Assignee: MANI, Inc.Inventors: Kanji Matsutani, Takashi Ina, Masahiko Saitoh, Mitsuru Saitoh
