Abstract: PURPOSE:To provide the phase shift mask which can exactly form light shielding film patterns by wet etching without undercuts and the process for production of such photomask. CONSTITUTION:This phase shift mask has a transparent substrate 2, a transparent conductive film 3 which is formed on the transparent substrate 2, the light shielding film patterns which are formed on the transparent conductive film 3 and are constituted of light transmissive parts 7 and light shielding parts 6, and phase shift layers 9 which are selectively formed in the light transmissive parts 7 of the light shielding film patterns. The light shielding parts 6 of the above-mentioned light shielding film patterns have transparent high-resistance films 4 under the light shielding films 5. On the other hand, both of the light shielding films 5 and the transparent high-resistance films 4 are removed in the light transparent parts 7. The generation of the undercuts is obviated at the time of removing a part of the light shielding films 5 constituting the light shielding parts 6 along the prescribed patterns and, therefore, the exact pattern etching is possible.

Title: Holding of polishing pad on platen in chemical machine-polishing device
Inventor: BARTLETT WILLIAM R
IPC: B24B37/16
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To surely attach/detach a polishing pad to/from the surface of a platen by providing a surface for receiving a polishing pad, a rotatable platen having a path penetrating through the platen to the surface, and a pump for exhausting air from the path. SOLUTION: When a computer opens a valve 204, a vacuum pump 200 feeds a suction force to a pad chuck chamber via fluid pipes 202, 206, 209 and an axial path 210. The pad chuck chamber distributes its suction pressure to respective radial paths 220 and secondly, the respective paths feed the suction pressure to a recessed part 226. The recessed part 226 distributes the suction pressure between holes 232 and these holes feed the suction pressure to the polishing pad 32. The relatively uniform differential pressure which is generated across the polishing pad 32 generates a net downward pressure for holding the polishing pad 32 on a platen assembly 30.

Title: Variable inductor
Inventor: HANAWAKA MASUO
IPC: H01F21/08
Filed: 1989-08-29
Abstract: PURPOSE:To obtain a variable inductor whose control electric power is small by providing the following in order to make a magnetic reluctance viewed from a winding for inductor use very large as compared with a magnetic reluctance viewed from a control winding: a second E-shaped magnetic path to which three legs have been connected without a gap part; and the winding for inductor use which has been wound on the central leg of the second magnetic path. CONSTITUTION:As viewed from a control winding a1-a2, a gap part does not exist in a closed magnetic path composed of a leg l6 to a leg l8 and this circuit can be saturated by a small electric current. On the other hand, as viewed from a winding b1-b2 for inductor use, closed magnetic paths composed of a leg l2-a leg l4-a leg l1-the leg l6 and of the leg l2-a leg l5-a leg l3-the leg l7 and the leg l2 surely passes gap parts g11 to g13 when the circuits are formed. Consequently, a large electric current is required in order to saturate the closed magnetic path composed of the leg l1-the leg l7. When the leg l6 and the leg l7 are satuarted gradually by a megnetic flux generated by an electric current flowing in the control winding a1-a2, a magnetic reluctance of the closed magnetic path constituted of the leg l2-the leg l4-the leg l1-the leg l6-the leg l2 or of the leg l2-the leg l5-the leg l3-the leg l7-the leg l2 becomes gradually large and an in ductance as viewed from the winding b1-b2 for inductor use is reduced.

Abstract: PURPOSE:To improve the strength of adhesion of the phosphor to the inner surface of an outer bulb, and to reduce the manufacturing cost by coating the mixture of the powder material such as phosphor and the powder glass on the inner surface of an outer bulb with the electrostatic coating. CONSTITUTION:Powder material such as the phosphor stored inside of a powder supplying device 1 is jetted from the tip of a powder material jetting spray gun 2, and this powder material is adhered to the inner surface of an outer bulb 3 electrostatically to from a powder material coated film. A static electricity generating device 4 is connected to the spray gun 2, and the bulb 3 is grounded. Namely, the powder glass having a low melting point is mixed in the powder material coated film, and the low melting point powder glass is fused or softened at the time of burning the film, and the powder material and the glass surface are adhered to each other to improve the foreign material strength. Since the cost of the powder glass is lower than that of the phosphor generally, the manufacturing cost of the coating film can be reduced. In this case, powder material and powder glass, especially the powder glass having a softening point at 300-800 deg.C, are mixed, and coated on the inner surface of the bulb 3 by the electrostatic coating to improve the strength of adhesion and reduce the cost.

IPC: F04B1/20
Filed: 1994-09-19
Abstract: PURPOSE: To prevent hooking of axial movement and to reliably exert a pre-load by a method wherein a spherical bush having a spring action is interposed as a pre-load member, exerting a pre-load between a shoe and a swash plate, between a fold down plate and a cylinder block. CONSTITUTION: In a swash plate axial piston machine, a piston is axially moved through rotation of a cylinder block 1, and a shoe 4 engaged with the piston is rotated over a swash plate 6. In which case, though a press force is needed so that the shoe 4 is not separated away from the swash plate 6, in this case, a spherical bush 11 in which a plurality of slits are formed is located between a fold down plate 7 and the cylinder block 1. The length in an axial direction of the spherical bush 11 is increased to a value slightly longer than a distance between the plate 7 and the cylinder block 1. This constitution exerts a force in an axial direction during assembly for holding down and presses the shoe 4 against the swash plate 6 through the generation of a spring action.
