Title: Valve timing controller for internal combustion engine
Inventor: HOSHINO AKIRA
IPC: F16K51/00
Filed: 1994-07-13
Abstract: PURPOSE:To discharge any foreign matter from an oil pressure control valve so as to suppress generation of malfunction due to bite of the foreign matter in the case when the foreign matter in operation oil bites in the oil pressure control valve. CONSTITUTION:An operation oil circuit comprises an oil pump 41, an oil filter 43, an oil pressure control valve(OCV) 44, a variable valve timing actuator(VVT actuator) 47, etc. An electronic control unit(ECU) 71 controls OCV 44 based on the detection results of various sensors. When ECU 71 judges bite of a foreign matter in OCV 44, a spool 52 is controlled to its advance angle side so as to be reciprocated on the increasing side of aperture amount of OCV 44. In the initial stage of starting of an engine, when operation oil hardly exists in OCV 44, the biting foreign matter can be fallen from OCV 44 by its dead load. Or, when the inside of OCV 44 is filled with operation oil and its operation oil is in its flowing condition, the foreign matter is discharged from OCV 44 together with the flow of the operation oil.

Title: Wafer transfer device
Inventor: MATSUO YOSHIYUKI
IPC: H01L21/68
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To reduce the transfer time by simplifying wafer transfer operation. SOLUTION: In an initial state of transfer operation, a housing member 39 having a wafer 37 set thereon is located above a vacant holding member 38 in the vertical direction V. The holding member 38 is enabled to pass through the internal space of the housing member 39 in the vertical direction V. A shift mechanism 35 lifts a mount stage 33 upward in the vertical direction V1 from the initial state so as to cause the holding member 38 set on the mount stage to pass through the internal space of the housing member 39 and to reach the upper side than the member 39 in the vertical direction V. When the holding member 38 passes through the internal space of the housing member 39, the holding member 38 supports and raises the wafer 37 held in the internal space from the lower side and detaches the wafer 37 from the member 39. Thus, the wafer 37 is transferred onto the holding member 38.
