Publication number: 20160344151Abstract: A connector (C) in which pin-like terminal fittings (6) project from the back surface of a housing (1) is held in a setting tool (9) including an opening (13). The connector (C) then is conveyed to an operation position together with the setting tool (9). At the operation position, a suction device (16) is located to communicate with the opening (13) from below and a nozzle (21) is located above the opening (13). Cooled dry ice fine particles are blown toward the housing (1) and the terminal fittings (6) from the nozzle (21). Foreign matters with reduced adhering forces by being cooled come off from the adhering surfaces and are sucked and collected by the suction device (16).Type: ApplicationFiled: August 8, 2016Publication date: November 24, 2016Inventors: Tomoya Itou, Yukinori Saka, Harald Lutsch

Patent number: 9227284Abstract: The inside of a case of a rotary table device is divided into a first space and a second space. The pressure of the first space is regulated to a pressure higher than the pressure of the second space during a steady state. The relationship between the pressures is reversed at a certain timing, to make the pressure of the second space higher than the pressure of the first space. Such operation can forcibly close a check valve disposed between the first space and the second space on regular basis, thereby preventing a malfunction of the check valve.Type: GrantFiled: April 30, 2014Date of Patent: January 5, 2016Assignee: FANUC CORPORATIONInventor: Tomoya Itou

Patent number: 8795007Abstract: A terminal fitting (10) includes a terminal main body (11) and a shell (12), which is a component separate from the terminal main body (11). The terminal main body (11) has a fitting portion (18) and resilient contact pieces (14). The shell (12) is a rectangular tube engaged with the fitting portion (18) of the terminal main body (11) and surrounding the resilient contact pieces (14). Even though being relatively expensive, an electrically conductive material such as copper alloy needs to be used as the material of the terminal main body (11) formed with the resilient contact pieces (14). However, an inexpensive material can be used for the shell (12) since electrical conductivity is not required. Therefore, cost can be reduced as compared with the case where a terminal fitting is made entirely of an expensive electrically conductive material.Type: GrantFiled: September 28, 2012Date of Patent: August 5, 2014Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Tomoya Itou, Shinji Iihoshi
