Filed: 1998-01-12
Granted: 1999-07-11
Abstract: A method for producing buried diffusion junction is disclosed. It consists of first forming an implant region before forming a shallow trench isolation structure, and forming an etching mask thereon, such that it will be not etched through to cause broken circuit when a shallow trench isolation process is subsequently carried out.

Title: Cable with impact-resistant coating
Inventor: BELLI SERGIO
IPC: H01B7/00
Filed: 1998-05-14
Granted: 2000-09-11
Abstract: The present invention relates to a coating for cables which is capable of protecting the cable against accidental impacts. By inserting into the structure of a power transmission cable a suitable coating of expanded polymer material of adequate thickness, preferably in contact with the sheath of outer polymer coating, it is possible to obtain a cable which has a high impact strength. The applicant has moreover observed that an expanded polymer material used as a coating for cables makes it possible to obtain a higher impact strength for this cable than using a similar coating based on the same polymer which is not expanded. A cable with a coating of this type has various advantages over a conventional cable with metal armor, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact as regards recycling of the cable once its working cycle is over.

Filed: 1998-05-19
Granted: 1999-08-21
Abstract: A container of the present invention has a valve and a lid which covers the valve from the outside.

Title: A method for manufacturing metal-oxide semiconductor field effect transistor components on a semiconductor substrate
Inventor: CHEN CHUN-YAO
IPC: H01L21/8232
Filed: 1998-06-19
Granted: 1999-11-11
Abstract: The present invention is a method for manufacturing metal-oxide semiconductor field effect transistor (MOSFET) components in which the width of metal silicide figuration is made to be thinner than that of polysilicon figuration below on purpose and metal silicide having metal silicide constituent is overlapped with a polysilicide gate structure having polysilicon constituent, and this polysilicide contour is formed by etching metal silicide figuration with an isotropic reactive ion etching and by etching polysilicon figuration with an anisotropic reactive ion etching. The metal silicide bottom figuration can be used when the high-temperature growth oxide is thicker than that of the polysilicon figuration of the lower layer vertical sidewall, and thus allows the light-doped source and light-doped drain and subsequent MOSFET channel length to be defined by the thin oxide at periphery of vertical sidewall polysilicon figuration.

Title: Weldless connector
Inventor: GOSHIMA KENICHI
IPC: F16L19/02
Filed: 1998-11-10
Granted: 2000-01-21
Abstract: The invention provides a kind of weldless connector that by reducing the twisting force for locking, the operation for replacement of inert gas and each connected machine can be more efficient. The weldless connector comprises two ducts which can move axially with no rotation in the connector body. And, during locking the fixtures screwed with the inner portion of the connector body, because the two ducts are press-connected when moving toward each other, the two ducts can be connected without welding. The washers in the connector body can prevent the leakage at the junction of  the two ducts and also prevent the leakage from the inner side of the connector body to the outer space. Besides, because the leakage from the inner side of the connector body to the outer space can happen between the connector body and its inner screwed fixture, there is no need for washers or sealing component around the fixtures in this weldless connector.

Title: Production of low sulfur syngas from natural gas with C4+/C5+ hydrocarbon recovery
Inventor: ALEXION DENNIS GEORGE
IPC: B01D53/48
Filed: 1999-04-22
Granted: 2002-04-11
Abstract: Sour natural gas is processed to remove the sulfur compounds and recover C4+/C5+ hydrocarbons by scrubbing the gas with an amine solution to remove most of the sulfur, followed cooling the gas to remove C4+/C5+ hydrocarbons and more sulfur compounds as liquid condensate to produce a gas having less than 20 vppm of total sulfur. The condensate is sent to a fractionator to recover the C4+/C5+ hydrocarbons. The sulfur and hydrocarbon reduced the gas is contacted first with zinc oxide and then nickel, to produce a gas having less than 10 vppb of total sulfur which is passed into a synthesis gas generating unit to form a very low sulfur synthesis gas comprising a mixture of H2 and CO. This synthesis gas is useful for hydrocarbon synthesis with increased life of the hydrocarbon synthesis catalyst and greater hydrocarbon production from the hydrocarbon synthesis reactor. Contacting the synthesis gas with zinc oxide further reduced the sulfur content to below 3 vppb.
