Abstract: A method of manufacturing a seamless tube formed of a titanium material, such as pure titanium or titanium alloys, by the use of the Mannesmann's method.  At first, an ingot formed of the titanium material is processed under the con-ditions that a heating temperature is 850 to 1,250 °C, the final temperature being 600 to 1,100 °C, and a working degree being 50 % or more to be turned into a solid billet.          The resulting solid billet is subjected to a piercing within a temperature range of .beta. transus - 100 to 1,250 °C to be turned into a hollow piece.  In this piercing process, in-clined rolls of a piercer are descaled.  The resulting hol-low piece is in case of need regulated a size thereof sub-jected to an elongating to be turned into a hollow shell.          Subsequently, the resulting hollow shell is subjected to a reducing (reducing conditions: temperature at an inlet side of the mill is 600 to 1,100 °C and a reduction of outside diameter is 80 % or more) by means of a reducer mill or to a sizing (sizing conditions: temperature at an inlet side of the mill is 550 to 1,150 °C and a reduction of outside diameter is 3 to 15 %) by means of a sizer mill.

Title: Fluid flow control method and apparatus for minimizing particle contamination
Inventor: MACK MICHAEL E
IPC: H01J37/18
Filed: 1990-02-21
Granted: 1996-07-02
Abstract: A fluid flow control for use with a process chamber.  In the disclosed embodiment, the process chamber is for ion implantation of a workpiece and the fluid flow control is to assure the flow rates are maintained at values which are efficient in evacuating and pressurizing the chamber but are not high enough to dislodge particulate contaminants from the process chamber walls.  In the disclosed design, the invention has utility both in instances in which wafers are directly inserted into the process chamber for ion implantation and in which the wafers are inserted into the chamber by use of a load-lock which avoids the requirement that the process chamber be cyclicly pressurized and depressurized.

Title: Partially or fully recessed microlens fabrication
Inventor: DERKITS GUSTAV E JR
IPC: H01L33/34
Filed: 1991-01-24
Granted: 1995-05-23
Abstract: Partially recessed microlenses are made in a substrate by a technique including the steps of forming a hard-baked patterned layer on a surface of the substrate, this patterned layer having at least one island portion surrounded by an auxiliary portion, and simultaneously etching this hard-baked patterned layer and the substrate to remove at least a portion of the thickness of the hard-baked layer. The island portions are located at areas overlying where microlenses are desired. The volume of the auxiliary portions of the hard-baked patterned layer is advantageously significantly greater than that of the island portions. Fully recessed microlenses are made by adding a step in the above technique, namely, the step of forming another hard-baked patterned layer covering only the auxiliary portions of the above-mentioned patterned layer prior to the etching.

Granted: 1998-08-04
Abstract: A process for injection molding a hollow plastic article (20) in which a low pre ssure heat-activated gas is injected in combination with a plastic material (28) into a mold cavity (30) of a plastic injection mold unit (32). When the plastic material (28) and heat-activated gas enter the mold cavity (30), the gas expands to outwardly exer t pressure on the plastic material (28) thereby urging the plastic material (28) towards the walls of the mold cavity (30) to, in turn, from the hollow portions (22, 24) of the hollow plastic article (20). The gas remains within the hollow plastic article (20) and continues to exert outward pressure until the plastic article (20) has substantially cooled and hardened at which time the gas becomes dormant. Accordingly, no venting of the gas from the plastic article (20) is necessary.
