Title: Fixture capable of clamping multiple workpieces at the same time
Inventor: YOU DAVID YING-HE
IPC: B23Q3/154
Filed: 2000-03-23
Granted: 2002-05-21
Abstract: This invention is related to a fixture capable of clamping multiple workpieces at the same time, comprising: a shaft, at least one expansion tube, and at least one nut. The expansion tube and a retaining tube are engaged over the shaft sequentially. An inner surface of the expansion tube and an outer surface of the shaft form a compartment. After the multiple workpieces are engaged over the expansion tube, the nut is threaded to the shaft for forcing the workpieces to align with one another. Fluid is injected into the compartment to apply pressure continuously, causing expansion of the expansion tube so as to be tightly fitted with the workpieces. The multiple workpieces are affixed to the shaft. The length of the shaft may be adjusted based on the needs, such that this invention is capable of clamping multiple workpieces at the same time.

Title: Objective lens of optical read-write head
Inventor: CHAO ZU-WEN
IPC: G11B7/00
Filed: 2000-06-07
Granted: 2002-11-21
Abstract: The present invention is an objective lens of optical read-write head and provides an objective lens using the mean of reflective light beam to converge the collimated light beams emitted from a laser beam source at a read-write light spot. In accordance with the technology, in which a reflecting optical element and a parabolic reflection mirror are included, disclosed in the present invention, the reflecting optical element can evenly reflect the collimated light beams emitted from a laser beam source onto the parabolic reflection mirror and, by the characteristics of a parabolic surface, all the collimated light beams are reflected at the focal point of the parabolic reflection mirror to form an optical read-write light spot. Since the light spot convergence technology applied in the present invention was not developed based on the principle of refraction, problems of optical aberration and narrowing of back focal length can be avoided at the same time when numerical aperture (NA) is widened.

Title: Staged aluminum deposition process for filing vias
Inventor: YU SANG-HO
IPC: C23C14/06
Filed: 2000-06-14
Granted: 2001-08-21
Abstract: The present invention is a semiconductor metallization process for providing complete via fill on a substrate and a planar metal surface, wherein the vias are free of voids and the metal surface is free of grooves. In one aspect of the invention, a refractory layer is deposited onto a substrate having high aspect ratio contacts or vias formed thereon. A PVD metal layer, such as PVD Al or PVD Cu, is then deposited onto the refractory layer at a pressure below about 1 milliTorr to provide a conformal PVD metal layer. Then the vias or contacts are filled with metal, such as by reflowing additional metal deposited by physical vapor deposition on the conformal PVD metal layer. The process is preferably carried out in an integrated processing system that includes a long throw PVD chamber, wherein a target and a substrate are separated by a long throw distance of at least 100 mm, and a hot metal PVD chamber that also serves as a reflow chamber.

Title: Ball screw and linearly movable apparatus using the ball screw
Inventor: MOCHIZUKI MASANORI
IPC: F16H25/22
Filed: 2000-06-26
Granted: 2001-11-11
Abstract: This invention relates to a ball screw and a linearly movable apparatus using the ball screw. The ball screw comprises a thread shaft, a nut member and a tubular retainer interposed between the thread shaft and the nut member so as to be freely, relatively rotatable in relation to them. The retainer has a plurality of ball retaining holes which are formed so as to correspond with the thread grooves, for retaining the balls in such a manner that the balls are exposed from the inner and outer surfaces of the retainer. The ball retaining holes have such a size as to hold balls in a freely rotatable condition. The outer ends of peripheral walls defining the ball retaining holes face the inside of the thread groove of the nut member. At least the minimum spacing between the outer ends of the peripheral walls is smaller than the diameter of the balls, and the thread shaft is longer than the nut member. With the above arrangement, the load sustainable by the nut member in an axial direction can be increased. In addition, the reciprocating linear movement of the nut member can be smoothly performed by the rotation of the thread shaft without formation of a ball return passage in cases where the distance of the linear movement of the nut member is short.

Title: Semiconductor light-emitting element and method of fabrication thereof
Inventor: OKAZAKI HARUHIKO
IPC: H01L33/16
Filed: 2000-08-11
Granted: 2001-09-21
Abstract: The purpose of the present invention is to provide a semiconductor light-emitting element and method of fabrication thereof to form current blocking structure precisely and easily, and to obtain a long-wavelength light semiconductor light emitting device from green to red light regime. The solution of the present invention is to use a light-emitting layer that is formed of laminated layers of a semiconductor having a larger lattice constant and a semiconductor having a smaller lattice constant to alleviate any ""mismatching"" of lattice constant between a substrate and a light-emitting layer. If the thickness of each layer is on the order of the wavelength of the de Broglie wave of electrons, or less than the ""critical thickness"" thereof, compressive stresses are applied to each layer so that the lattice constant thereof can become closer to that of the substrate with no generation of crystal defects. If a region comprising an n-side electrode material is formed in part of a region in which a p-side electrode is formed and is then annealed, the resultant reaction between the metals of those electrodes will form a region with a high contact resistance.

The signal transition time is set at least twice the delay time, which extends from the send-out point to the nearest branch of the wiring. Thus, it is capable of executing the transmission of signals with mitigated reflection by the nearest reflection point.

The classification database is updated when an anomalous measurement is encountered, even as monitoring of the mechanical component continues in real-lime. The invention also provides a dimensionless peak amplitude data feature and a dimensionless peak separation data feature for use in classifying.
