Publication number: 20120107168Abstract: An iron-based sintered sliding member that contains no free cementite in its structure and is excellent in tribological property such as friction and wear, and a method of manufacturing that iron-based sintered sliding member are provided. To iron powder as a main component, 3-20 mass % alloy powder, which comprises 4-6 mass % manganese, 3-5 mass % iron, and copper as a remaining component, and 1-5 mass % carbon powder are blended, and mixed to obtain powder mixture. Then, the powder mixture is filled in a mold and compacted to make a green compact of a desired shape. This green compact is sintered at a temperature of 1000-1100 degrees Celsius for 60 minutes in a heating furnace whose inside is adjusted to be a neutral or reducing atmosphere.Type: ApplicationFiled: May 24, 2010Publication date: May 3, 2012Applicant: OILES CORPORATIONInventor: Yasuhiro Shirasaka

Patent number: 7659946Abstract: Disclosed is a transmissive liquid crystal projector carrying a vertical alignment liquid crystal device. The liquid crystal projector includes a liquid crystal panel (25), on the light incident side and on the light radiating side of which a light incident side polarizing plate (24) and a light radiating side light polarizing plate (26) are arranged, respectively. A first polarized light component in a light beam collected by an illuminating optical system is transmitted through the light incident side polarizing plate (24) and routed to the liquid crystal panel (25). An optical anisotropic device (45), tilted by a preset angle correlated with the direction of alignment of liquid crystal molecules in the liquid crystal panel (25), that is, a pre-tilt angle, is arranged between the light incident side polarizing plate (24) and the liquid crystal panel (25) or between the light radiating side light polarizing plate (26) and the liquid crystal panel (25).Type: GrantFiled: June 13, 2005Date of Patent: February 9, 2010Assignee: Sony CorporationInventors: Yasuhiro Shirasaka, Hitoshi Inukai, Tomoya Yano
