Title: Microwave plasma treatment device
Inventor: TOKI MASAHIKO
IPC: C23C16/50
Filed: 1986-11-20
Abstract: PURPOSE:To increase a treatment speed and to improve the quality of a formed film by using plural light transmissive Al2O3 plates laminated via a heat transfer sheet to form a microwave transmission window plate and cooling the waveguide side thereof with flowing gas so that the failure of the window plate is hardly generated and the microwave incident electric power is safely increased. CONSTITUTION:The above-mentioned window plate 2a is formed by laminating two sheets of the light transmissive Al2O3 plates 21 via the heat transfer sheet 22 opened with a microwave transmission part and interposed between said plates and further adhering the heat transfer sheet 23 having the aperture larger than the aperture of said sheet 22 on a plasma forming chamber 3 side. The window plate 2a is supported by a holder 24 of Al, etc., which is held in tight contact with the entire peripheral surface of the microwave transmission part. In addition, the waveguide 1 side of the window plate 2a is cooled by the flowing gas such as N2 from a gas blow port 25 at the end of the waveguide 1. The heat after heating the window plate 2a is transferred by the effect of the sheets 22, 23 to the peripheral part of the window plate 2a and is absorbed in the holder 24. The accumulation of the heat in the Al2O3 plates 21 is thus decreased and dispersed by such absorption coupled with the cooling by the above-mentioned gaseous N2. The temp. rise and thermal stress of the plates 21 are thus decreased and the failure of the window plate 2a is hardly generated.

IPC: H01L21/30
Filed: 1985-12-11
Abstract: PURPOSE:To shorten a downtime by a method wherein exposure processing is interrupted when a predicted information specifying the fluctuation of imaging characteristics is dissipated, the fluctuation of imaging characteristics is observed at a plurality of points on a time base, a precise predicted information is computed and correction control is restored when a mask pattern is projected and exposed and processed.

Data, such as a time constant on the magnification fluctuation characteristics of the projection lens 5, the amount of light of transmitted lighting beams, magnification variation to the quantity of pressure regulation, etc. are memorized previously to the pressure regulator 20. The pressure regulator 20 computes the magnification variation of the projection lens 5 at that time on the basis of these data and predicted informations capable of momently changing, calculates a pressure value correcting the variation and controls the pressure of an air chamber 5a. Accordingly, when informations corresponding to incident hysteresises dissipate, correction control can be restored rapidly to the correction control of imaging characteristics having high precision.

Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To complete working hole forming works in one process by wrapping a sheet having releasing property round a main cover formed by precast concrete to be used as it is as a form for a slab. SOLUTION: In the periphery of a form common to main cover for a slab working hole which is a precast product, a sheet suitably made of a raw material suitable to releasing from concrete is wrapped and installed in a place where to form a working hole.

Title: Impeller of mixed flow pump
Inventor: OKAMURA TOMOYOSHI
IPC: F04D3/02
Filed: 1993-11-09
Abstract: PURPOSE:To always develop secondary flow or separation in a partial flow territory so as to provide a stable pump head-flow characteristic downward right by providing projecting parts of small radius of curvature of angle on the negative pressure face of the leading edge of the blade of a movable blade impeller. CONSTITUTION:When projecting parts are provided on a movable blade impeller 1, the radius of curvature of the angle on the negative pressure face side of the projecting leading edge is set to be small, so that flow is always separated at the same position of the angle of a leading edge in a partial flow territory even if the blade fitting angle is changed. For example the leading edge of a blade 2 is provided with plate-like ribs 5 of less height than the maximum thickness of the blade instead of a solid projection as a projecting part. The rib 5 of one of several pieces are provided along the leading edge on optional positions of the leading edge part. Because the angle 5a of the rib is formed acute, it is suitable for the movable blade impeller 1 in particular. Hereby against an existing impeller having unstable part in the pump head-flow characteristic (Q-H characteristic), it is suitable for correction stabilizing the Q-H characteristic by additional working.
