Title: Air suction type screw tightening bit
Inventor: SHIODA RYOSUKE
IPC: B25B23/10
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To improve an air suction type screw tightening bit provided with an outer tube for air suction. SOLUTION: The outer tube of a conventional air suction type screw tightening bit is eliminated. An extended groove 3 connected to an engagement groove appearing on a section perpendicular to a main shaft 1 of an action part of the main shaft 1 is provided on the main shaft 1 along a longitudinal direction of the main shaft 1. The extended groove 3 is covered with a thin cover 4 made of tetrafluoroethylene. A closed passage 5 formed with the cover 4 is used as an air suction passage. Since the diameter of circumference of the main shaft 1 is reduced due to elimination of the outer tube, the threaded hole 'b' which can not have been coped with by a conventional tightening bit due to an obstacle existing in the surroundings can be coped with.  Since a shape of a section of the air passage 5 is in a shape based on an engagement shape of a head of a screw 50 with the engagement groove 51, the section size of the air passage is greatly reduced as compared with a passage of a section over the whole circumferential surface of the main shaft 1 like the conventional screw tightening bit, and the sucking force of this bit is greatly different from that of the conventional air suction type screw tightening bit even under the same sucking pressure.

Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring thickness of film using the FTIR method, which can measure the thickness of each layer of a plurality of thin film layers formed on a substrate at one time, and to provide a method for manufacturing semiconductor wafer employing the method for measuring thickness of film. SOLUTION: The method for measuring thickness of film employs the FTIR method. Infrared rays are projected on a semiconductor wafer EPW in which the plurality of thin film layers E1, E2 having dopant concentrations different from each other are formed on the substrate S, and the creation of interferogram based on the measurement of reflecting light is carried out more than one time. A plurality of created interferograms are multiplied, and thereby side burst signals 11, 13 based on the reflecting light from the interface of the substrate S and the thin film E1 and from the interface of the thin films E1, E2 are recognized easily. Then, each thickness of thin films E1, E2 is measured respectively. This measurement is carried out after the plurality of thin film layers E1, E2 having the dopant concentrations different from each other are successively formed on the substrate S.
