Filed: 1993-06-11
Abstract: PURPOSE:To obtain a vacuum processing device which restrains a work from increasing in distribution temperature difference, prevents gas from leaking out, and accurately processes a work by a method wherein a suscepter and an electrostatic chuck sheet or the like of an electrostatic chuck mechanism are provided inside a processing chamber. CONSTITUTION:A suscepter 9, an electrostatic chuck sheet 17 of an electrostatic chuck mechanism 16, gas blowoff holes 28, a gas dispersing groove 30 are provided inside a processing chamber 1 formed high in airtightness. Gas is uniformly diffused over the rear side of a work 5 through the intermediary of the gas dispersing groove 30 between the work 5 and the electrostatic chuck sheet 17 of the electrostatic chuck mechanism 16 which holds the work 5 by attraction with an electrostatic force. Therefore, the work 5 and the electrostatic chuck sheet 17 can be enhanced in thermal conductivity between them, so that heat can be uniformly transmitted to the work 5 from the suscepter 9. Furthermore, gas is discharged out through an exhaust hole 34 provided to the electrostatic chuck sheet 17, whereby gas is prevented from leaking out through a gap between the work 5 and the electrostatic chuck sheet 17.

Abstract: PURPOSE:To open and close a lid without using a stay by providing at a hatch aperture edge section, an elastic stopper that can support the lid as well as allow the flange terminal to pass through due to its elastic deformation although it protrudes into the moving trace of the flange terminal of the lid. CONSTITUTION:A lid 2 with a peripheral flange 2a is so arranged as to cover a hatch aperture edge section 3 formed by rising from a deck 1, while being mounted to one side of the aperture edge section 3 through a hinge member 8 so as to freely open and close. In addition, an elastic stopper 9 that protrudes into the moving trace L of the flange terminal 2a of a lid 2 is provided inside the hatch aperture edge section 3. This elastic stopper 9 permits the flange terminal 2a of the lid 2 to pass through due to its elastic deformation and has a protrusion 9b that supports the lid 2. As a result, since there is no stay at the hatch opening section as before, cargoes can freely be taken in and out.

Title: Measuring instrument for loss of optical fiber
Inventor: FURUKAWA SHINICHI
IPC: G01M11/00
Filed: 1985-07-26
Abstract: PURPOSE:To eliminate the need for a mode control part and to measure the loss of light accurately by connecting a light source, a photocoupler, and a photodetector mutually through a mode control light optical fiber and measuring back scattered light from one terminal of an optical fiber to be measured. CONSTITUTION:A pulse generator 2 generates and inputs a pulse to the laser beam source 3 with a timing signal from a signal processing part 1, emitting pulse light. This pulse light is made incident on the optical fiber 10 to be measured through a mode control optical fiber 14, a directional photocoupler 6, and a receptacle 7. The back scattered light is received by the photodetector 8 through the directional photocoupler 6 and a mode control optical fiber 15 and the signal processing part 1 calculates a loss distribution. The measured value of the light loss depends upon the mode distribution of the light greatly, so a stationary mode distribution needs to be obtained by limiting the high order mode, but the mode control optical fibers are used to eliminate the need for a mode control part.

Title: Psk demodulation circuit
Inventor: INAGAWA OSAMU
IPC: H04L27/227
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a carrier phase error detector by employing a method that calculates a carrier phase error of each transmission system through the arithmetic operation from an absolute phase and using each carrier phase error detector in common. SOLUTION: An absolute phase detector 19 obtains an absolute phase from inputs of an in-phase signal demodulation input terminal 17 and a quadrature signal demodulation input terminal 18. Then a phase error calculation device 20 obtains a phase error in matching with an input from a transmission system input terminal 16 based on the absolute phase and outputs the phase error to a carrier phase error output terminal 21. A phase error calculation section 20 uses an equation of phase error=A%2<(n-m)> -2<(9-m)> (A is an integer). Since modulation phases are 2, 4, 8, 16, when m'1,2,3,4 are used in the equation above, n=10 is obtained because an absolute phase output has 10-bit.  A selector is selected by an input from the transmission system input terminal 16 so as to calculate the phase error of 2, 4, 8, 16 phases by a specific equation by using n=10 and an arithmetic output is a phase error.

Title: Production of chromium chromate steel sheet
Inventor: KOJIMA MASAYUKI
IPC: C25D5/26
Filed: 1983-09-12
Abstract: PURPOSE:To obtain a titled steel sheet having extremely good adhesion by using mechanical stripping to remove the Cr hydroxide codepositing in plating treatment by a two-step method consisting of Cr plating and forming of Cr hydroxide. CONSTITUTION:Metallic Cr is plated on the surface of a strip 10 in a Cr plating stage and thereafter the Cr hydroxide codeposited on the metallic Cr is removed by the treating stage for the same. Both surfaces of the strip 10 are rubbed up by, for example, brush rolls 1, 1 formed of PP, nylon, etc. for the above-mentioned purpose. A better effect is obtd. if water is sprayed in the arrow direction in this stage. The codeposited Cr hydroxide which affects adversely the adhesion is gelly-like and soft before drying and therefore when the hydroxide is mechanically rubbed up, the hydroxide is thoroughly stripped. The Cr hydroxide is formed on the thoroughly exposed metallic Cr in the succeeding treating stage and the chromium chromate sheet having excellent adhesion is thus obtd.

Title: Swash plate type axial piston pump
Inventor: KANAMARU NAONOBU
IPC: F04B1/20
Filed: 1987-07-06
Abstract: PURPOSE:To simplify the structure by letting the synchronized rotation drive of both a cylinder barrel with a cylindrical hole and rocking plate be performed by a drive rod. CONSTITUTION:When a drive shaft 1 is rotated, a cylinder barrel 2 is rotated so as to let a rocking plate 3 be rotated while being synchronized with a tilting plate 6 via a drive rod 5 for reciprocating a piston 4 to the shaft direction. The change of tilt angle allows a ball head 17 to move freely along a driving groove 20 so as to be identical with the pitch circle of a drive hole 21, the synchronized rotation is thereby possible correspondingly to the change of tilt angle. This constitution thereby enables the structure to be simplified without impairing the piston performance, thereby enabling the synchronized rotation positively.
