Patent number: 10355574Abstract: This disclosure discloses a linear motor including a stator, a mover, and a plurality of teeth. The stator includes a stator curved part having an arc shape in a longitudinal direction. The mover is arranged facing the stator and is moved in the longitudinal direction of the stator. The plurality of teeth are arranged in parallel along the longitudinal direction so that a pitch of the teeth at an outer-peripheral side is larger than the pitch of the teeth at an inner-peripheral side on the stator curved part.Type: GrantFiled: June 3, 2016Date of Patent: July 16, 2019Inventors: Shogo Makino, Toru Shikayama, Masanobu Kakihara, Masayuki Hirayama, Haruki Yahara

Patent number: 7616516Abstract: A semiconductor device of the present invention has a memory cell array having plural CMOS static memory cells provided at intersecting portions of plural word lines and plural complementary bit lines. In the memory cell array, a switch MOSFET which is in an OFF state in a first operation mode and in an ON state in a second operation mode different from the first operation mode and first-conductivity-type and second-conductivity-type MOSFETs having a diode configuration are provided in parallel between a first source line to which sources of first-conductivity-type MOSFETs constituting first and second CMOS inverter circuits constituting the plural static memory cells are connected and a first power supply line corresponding to the first source line. A second source line to which sources of the second conductivity-type MOSFETs constituting the first and second CMOS inverter circuits are connected is connected to the second power supply line corresponding thereto.Type: GrantFiled: April 24, 2008Date of Patent: November 10, 2009Assignee: Hitachi ULSI Systems Co., LtdInventors: Masayuki Hirayama, Masami Hasegawa, Michitaro Kanamitsu, Yayoi Hayashi, Naoyuki Anan
