Filed: 1998-11-26
Granted: 2001-05-28
Abstract: Procedures are disclosed for supporting roaming subscriber mobile station access to stored subscriber data messages.

In another aspect, a mailbox established for a given subscriber mobile station in the home message center is transferred (perhaps on a periodic basis) for storage in a local mailbox of a proximate message center within a cellular telephone network where the subscriber is currently roaming. In either case, the storing message center thereafter performs any requisite operations needed to facilitate message forwarding to or retrieval by the addressee subscriber mobile station.

Title: Semiconductor chemical sensor
Inventor: LIVINGSTON PETER M
IPC: G01N27/00
Filed: 1998-12-01
Granted: 2001-06-23
Abstract: A chemical sensor for detecting a chemical species in a gas comprises a detector element including a porous organic semiconductor comprised of a material on which the chemical species in the gas is adsorbed. The chemical sensor further comprises a power source for producing a bias voltage and a depletion region in the detector element. The chemical species percolates through the organic semiconductor and into the depletion region under the bias voltage, causing a change in the capacitance of the detector element. A light source irradiates the gas with light before entering the detector element. The light changes the chemical properties of the chemical species and enhances the adsorption selectivity of the organic semiconductor. The chemical sensor can determine both the presence and concentration of the chemical species in the gas based on the change in capacitance in the detector element. The chemical sensor can be provided in a portable unit suitable for field testing applications.

Abstract: There is disclosed a method for fabricating a shallow trench isolation indirectly by chemical mechanical polishing. After depositing the oxide material in the shallow trench, the shallow trench isolation having planar level is formed by etching back and the silicon nitride layer at the corner of the active area is exposed. A blanket mask layer is then deposited. After the mask layer is formed, a photoresist layer is formed to remove a portion of the mask layer in the wide active area. The photoresist layer is then stripped and chemical mechanical polishing is performed to remove the mask layer on the narrow active area. The oxide material on the active area is removed by wet etching, and the remained mask layer and the silicon nitride are then etched by wet etching. Finally, the pad oxide layer is removed, so as to complete the method for fabricating the shallow trench isolation indirectly by chemical mechanical polishing in accordance with the present invention.

Granted: 2001-09-21
Abstract: In a separator 10, a seesaw cover 13 is pressed downward at its rear end 13b to turn the seesaw cover 13 counterclockwise to form an open mouth 34. A label comprising a printing tape and a cover tape attached through an adhesive layer to the printing tape is inserted at one end into the open mouth 34. The seesaw cover 13 is released from the push force applied from above to its end 13b opposite to the mouth 34, the cover 13 is returned to its original position by the resiliency of a spring 29, and the label is then clamped at one end by elastic members 24 and 25 within the mouth 23. When a push button 14 is pressed downward, a pair of sliding contact surfaces 17a thereof slide on a corresponding pair of sliding contact surfaces 18c of a moving member 18 to thereby move the moving member 18 toward the mouth 23. This causes a curved member 21 provided at a mouth-side end of the moving member 18 and hence its curved member surface 21a to curve a corner of the label. When the pushing and releasing operations of the push button 14 are repeated several times and then the label is taken out, the cover tape and the printing tape of the printing laminate label are separated from each other at the corner.
