Title: Vane type fluid machine
Inventor: TANAKA KATSUZOU
IPC: F04C2/344
Filed: 1982-07-15
Abstract: PURPOSE:To make the directions of suction and discharge changeable by constituting such that a cam ring may be eccentric on both sides thereof, to simplify the positioning of the fluid machine by giving the same function to both suction and discharge ports, and as well to enable the fluid machine to be used under high pressure. CONSTITUTION:When a cam ring 105 is made eccentric in the direction A by means of external force, liquid is sucked into the cam ring 105 from a suction area 114, and is discharged through a discharge area 115. When the cam ring 105 is made eccentric in the direction B which is opposite to the above-mentioned direction A, the suction area 114 and the discharge area 115 are changed into the discharge area 114 and the suction area 115. Further, a suction port 112 and a discharge port 113 are incorporated in a high strength cap 101 and a port plate 111 so that a high pressure type vane pump may be obtained. Further, since the suction port and the discharge port may have the same function, the disposition of the pump may be simplified.

Title: Plane fresnel lens
Inventor: TAKADOU NOBUKAZU
IPC: G02B6/124
Filed: 1984-06-14
Abstract: PURPOSE:To draw a bright lens of a small F-number even if an electron beam having a large diameter is used by disposing alternately Fresnel zones on the right and left of the virtual center line intersecting orthogonally with the propagating direction of the light beam. CONSTITUTION:The lens part 31 having a high refractive index is drawn by irradiation of an electron beam to part of amorphous arsenic sulfide 13 of a plane Fresnel lens. The lens parts 31 are alternately arranged on the right and left of the virtual center line 32 intersecting orthogonally with the propagating direction of the light beam. The overlap of the two adjacent Fresnel zones is thus obviated and the cross width amin of the zones is made smaller. Since the F-number is proportional to amin, the F-number can be diminished by making the same smaller. The F-number is thus made 1.2 and the drawing of the bright Fresnel lens is made possible even if 0.3mu electron beam is used.

Title: Method of adjusting magnesium component of molten aluminum
Inventor: DATE TOMOO
IPC: C22B21/06
Filed: 1988-05-19
Abstract: PURPOSE:To improve the yield of molten Al and to facilitate Mg component adjustment by melting Al scrap, subjecting the resulted slag part to Mg removal in a regenerating furnace to form an ingot and charging the same into the molten metal from which the slag is removed. CONSTITUTION:The Al scrap is melted in a melting furnace. The upper layer part of the molten metal contg. the formed slag at a high ratio is taken out and is transferred into the regenerating furnace. The temp. of the above- mentioned slag part is increased to about 750-800 deg.C at this time. The Mg in the molten metal is thereby oxidized and is risen and separated into the slag. The Mg of the molten metal is thus removed. The ingot is produced from the molten metal subjected to such heating and Mg removal treatment and is stocked. The stocked ingot is charged into the molten metal from which the slag part is removed in the above-mentioned melting furnace. The content of the Mg in the molten Al is thereby decreased and the Mg component adjustment is easily executed; in addition, the yield of the molten metal is improved.

Title: Semiconductor laser element
Inventor: ASAHARA YOSHIYUKI
IPC: H01S5/022
Filed: 1985-06-08
Abstract: PURPOSE:To enable a regularly shaped laser beam to be emitted without using additional optical element, by incorporating a slab-form lens including one directional refractive index distribution in a protective cover glass required for a semiconductor laser element. CONSTITUTION:The opening of a package 10 in which a semiconductor is stored is covered with a glass 8 incorporating a slab-form refractive index distribution type lens 9. Since the X-Z plane having the maximum refractive index in this lens 9 makes alignment of the junction surface of a semiconductor, the beam emitted from the semiconductor 1 passes through a refractive index distribution area of a cover glass. Thus, the vertically enlarged angle is reduced and the beam form can be arranged from an elliptic form to a circular one approximating to a circle. The beam emitted from the semiconductor laser element can be arranged to be parallel by arranging thickness of the glass plate or variation of the refractive index, according to the maximum enlarged angle and minimum enlarged angle direction of the semiconductor laser beam.

The vessel containing the formed article is inserted into a calcination furnace and heated in an oxidizing atmosphere to obtain a sintered material (ceramics). The scattering loss of Bi is suppressed to 2-3% of the charged amount by this process and a superconductor having stable quality can be produced.
