摘要： PROBLEM TO BE SOLVED: To provide a DAST (4-dimethylamiuo-N-methyl-4-stilbazolium tosylate) single crystal having uniform electro-optic characteristics over whole crystal, and to apply the DAST single crystal as an electro-optic device. SOLUTION: The DAST single crystal having uniform electro-optic characteristics over whole crystal is obtained by sufficiently purifying a DAST raw material for producing the single crystal by recrystallization and combining an SNM method and a specific gravity difference solvent purifying method. That is to say, the DAST single crystal is obtained by growing the single crystal by the SNM method from a DAST solution containing the DAST raw material purified by recrystallization and purifying by moving the DAST single crystal into an inert solvent layer having a specific gravity larger than that of the DAST solution. The DAST single crystal having uniform electro-optic characteristics can be applied in an electric field detecting device without determining the mutual positions of a light source, the DAST single crystal and a light receiving section.

摘要： An optical element being high in productivity and capable of ensuring a large bonding area, and a production method of the optical element. At mold opening when a top part (120) provided with a round portion (121) moves upward, a preform is placed in an inner space the interior of which is formed by a rectangular sleeve (110) and the round portion (131) of a bottom part (130). At mold clamping when the top part (120) moves downward, the preform is pressurized. That is, a convex lens portion is transferred by the concave curved surface (122) and the edge surface (123) of the round portion (121) and the concave curved surface (132) and the edge surface (133) of the round portion (131). The four side surfaces of an optical element (1) are transferred by the inner wall surface (110a) of the sleeve (110). Further, part of the preform jumps out into the gap portion (140) between the outer peripheral surfaces (121a, 131a) of the round portions (121, 131) and the inner wall surface (110a) of the sleeve (110) to thereby form a protrusion portion of the optical element (1). The optical element (1) has a marker (2) formed on the top surface (11a) of its body, and the marker (2) may be formed to extend linearly along the optical axis of lens portions (12, 16). The marker (2) is formed to protrude from the top surface (11a). The side surface (11b) and the side surface (11c) of the body may be formed such that the separating distance between the side surface (11b) and the side surface (11c) gradually increases toward a bottom surface (11d).

摘要： A conductive silicon nitride composite sintered body having an average grain size of 100 nm or less and whose relative roughness (Ra) after electric discharge machining is 0.3 μm or less can be obtained by grinding/mixing a silicon nitride powder and a metal powder together until the average particle size of the silicon nitride powder becomes 30 nm or less, and subsequently by molding and sintering. It is preferable that the crushing/mixing is continued until it is apparent that a peak of added metal in an X-ray diffraction pattern has disappeared during the crushing/mixing.

摘要： An object of this invention is to prevent drop of life of a bearing by an axial force when using a pump as a compressor. In a vacuum pump 1 compressing and discharging gas in a direction of a rotor axis by rotation of screw rotors 3, 4 engaged together which are supported rotatably in a casing 2, balance pistons 13, 14 are disposed on shafts 6, 7 of said screw rotors at inlet side of said casing. The balance pistons separate a receiving section 17 at area of the screw rotor and a pressurizing section 16 at area of the balance piston, and a thrust force of the screw rotors at a pressurizing condition is canceled by acting the discharge pressure in the pressurizing section. The pump is used as a compressor when the discharge pressure is acted on the balance pistons 13, 14. When the pump is used as a vacuum pump, air at discharge side is sucked as cool air through a cooler toward a place near to the discharge side of the receiving section 17 at area of the screw rotor.

摘要： A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11. A support rod 8 is inserted in the shaft member 11 to support the shaft member 11 for rocking motion about a pivot axis C2 orthogonal to the shaft member 11. The pivot axis C2 is inclined backward in the direction of belt travel with respect to the direction of load on the shaft member 11. With this configuration, when the drive belt 3 deviates to one side, the pulley body 5 is immediately angularly moved so that it is inclined with a level difference with respect to the direction of load on the shaft member 11 and is positioned obliquely relative to the drive belt 3, thereby producing a force of returning the drive belt 3 to its normal position.
