Patent number: 12325065Abstract: A method for producing a metal matrix composite by compounding a matrix material and a reinforcing material. The metal matrix composite has a near-net shape with high dimensional accuracy and a high reinforcing material volume ratio (Vf %). The matrix material is a pure metal or an alloy, and the reinforcing material includes ceramic particles, graphite particles, and/or metal particles, and the reinforcing material is different from the matrix material. The method includes molding a reinforcing material-molded or filled body having a near-net shape and pores, in a metal mold having a cavity corresponding to the near-net shape, pre-heating the mold including the reinforcing material-molded or filled body, placing the mold in an outer shell metal mold, casting a molten matrix material into the pores of the reinforcing material-molded or filled body, thereby obtaining the metal matrix composite. The method uses the same mold throughout the entire process.Type: GrantFiled: December 23, 2022Date of Patent: June 10, 2025Assignee: ADVANCED COMPOSITE CORPORATIONInventors: Yoshio Takagi, Hitoshi Kitamura, Shogo Ochiai

Publication number: 20250109461Abstract: An object of the present invention is to develop a technique for providing a novel metal matrix composite capable of stably suppressing problems of conventional composites formed with a reinforcing material and a matrix material, such as a metal, the problems being, for example, inferior mechanical properties such as tensile and bending strengths to those of single-phase materials, such as a metal, coarser surface roughness due to, for example, chipping and wear of a cutting edge caused by fall-off of a reinforcing material or collision of a blade with a hard reinforcing material during precision shaping machining, and inferior workability.Type: ApplicationFiled: December 23, 2022Publication date: April 3, 2025Inventors: Yoshio TAKAGI, Hitoshi KITAMURA, Shogo OCHIAI

Publication number: 20240157441Abstract: A dissimilar metal joint structure includes a first and second joining materials and a three-dimensional structural body. The structural body is joined to the top of the first joining material. Spaces in the structural body are filled with the second joining material, so that the second joining material is geometrically integrated with the structural body. The structural body is joined to the first joining material at an interface. The second joining material is charged into the spaces in the structural body and is integrated with the structural body. The first and second joining materials are joined together via the structural body. Because the second joining material is charged into the spaces in the structural body, the second joining material and the structural body are strongly joined and integrated together by the anchor effect. Inducing metallurgical reaction at the interface between the first and second joining materials can increase bonding strength.Type: ApplicationFiled: March 28, 2022Publication date: May 16, 2024Applicant: ADVANCED COMPOSITE CORPORATIONInventors: Yoshio Takagi, Khin Khin Hset N/A, Shogo Ochiai, Hitoshi Kitamura

Patent number: 8128741Abstract: A dissolving apparatus has a cylindrical tubular container closed at both ends with its center axis being inclined to the horizon. A center of an interface between a gas and a liquid in the container is positioned at a center in a lengthwise direction of a side wall of the container. Two inner spaces of the container above and below the interface are referred to as a gas section and a liquid section. An injection inlet for injecting a gas-liquid mixed fluid into the container is provided at a level corresponding to, or lower than, the interface. A liquid outlet for discharging the liquid is provided near a bottom of the liquid section of the container. Since the container is inclined, the interface can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet with large gas bubbles being present therein.Type: GrantFiled: May 28, 2007Date of Patent: March 6, 2012Assignee: Panasonic Electric Works Co., Ltd.Inventors: Yasunari Maeda, Shigeyuki Yamaguchi, Kazumasa Rokushima, Naoki Shibata, Hitoshi Kitamura, Noriyuki Kitachi, Yoshihiro Itou, Takaya Niu

Patent number: 8099802Abstract: Flush toilet equipment comprises a bowl, a flush mechanism that supplies flush water to the bowl through a flush water passage, and a minute bubble generator. The minute bubble generator generates minute bubbles. The bubbles are 0.1-1000 ?m in bubble diameter and mixed with the flush water. In this construction, since the minute bubbles are fully diffused into the flush water, various effects such as improvement of toilet flush effect, etc. can be further enhanced.Type: GrantFiled: July 26, 2006Date of Patent: January 24, 2012Assignee: Panasonic Electric Works Co., Ltd.Inventors: Shigeyuki Yamaguchi, Hitoshi Kitamura, Yasunari Maeda, Takaya Niu, Kazumasa Rokushima, Yoshihiro Ito, Naoki Shibata, Noriyuki Kitachi, Masato Suzuki
