Patent number: 12007756Abstract: A machining assist system includes a knowledge database, a receiver, a control unit, and a display. The knowledge database stores various pieces of information indicative of know-how concerning a machining method and a machining facility. The receiver receives a question. The control unit executes a driving solver and a solution-providing solver so as to search the knowledge database using a search condition based on the question and derive a response. The display presents the response. The response includes a plurality of measures, priorities assigned to the measures, and progress information indicative of a search process and a search route. The search process includes a plurality of factors to be used to derive the measures. The search route is a link between the factors. The search process and the search route are visually presented on the display.Type: GrantFiled: September 24, 2019Date of Patent: June 11, 2024Assignee: JTEKT CorporationInventors: Hiroshi Kojima, Yoshihiko Yamada, Takayuki Azuma, Toshiki Sakai, Shigetoshi Noritake, Kazunari Teramoto

Patent number: 5395562Abstract: A sintered product based on mesocarbon microbeads is prepared by pressure-molding mesocarbon microbeads (MCMB) having an MSP (maximum solubility percent) value of 30 to 38% by volume whereby a body is formed, and sintering the body, wherein MSP represents the percentage volume reduction (volume %) determined by heating a given amount of an MCMB to 350.degree. C. under a pressure load of 10 kgf/cm.sup.2. The quality of a molded MCMB sintered product can be controlled by determining the percentage volume reduction (MSP) of an MCMB by heating it under a given pressure load in a predetermined space using the MSP value so found as an indicator.Type: GrantFiled: April 2, 1993Date of Patent: March 7, 1995Assignee: Osaka Gas Company, Ltd.Inventors: Yoshiteru Nakagawa, Takayuki Azuma, Hideki Tamamura, Tadashi Murakami, Norio Murakami, Yasuo Minamitani, Noboru Mimura
