Title: Method of constructing gravity-type marine structure and structure by same
Inventor: SEKI ATSUSHI
IPC: E02B17/02
Filed: 1993-12-17
Abstract: In constructing a gravity offshore structure at an installation site having a relatively large depth of water, a footing (2) serving as a float as well is built in a dry-dock, and a cylinder (4) which constitutes an underwater substructure is built on the footing (2) in an offshore yard located at a shallow sea area. The cylinder (4) is assembled in a telescopic manner, and an upper cylinder (4C) serves as a float. Ballast water Wb is injected into the footing (2) at the installation site of a large depth of water to submerge the footing (2), and a lower cylinder is extended while the upper cylinder (4C) acts as a float. After the footing reaches the bottom of the water, a pad material is filled in the footing (2) and the cylinder (4), and an offshore superstructure is constructed on the upper portion of the cylinder (4). Since a cylindrical-shaped underwater substructure is built in a telescopic manner on the footing serving as a float as well, a structure for a large depth of water can be built with easy stability as a float even in a region where it is not possible to ensure a calm sea area of a large depth along the coast. Buoyancy and gravity are harnessed at an installation site having a large depth of water to readily extend a body and submerge a huge structure without the use of a large-scale drive apparatus.

Title: Semiconductor laser device
Inventor: MURO KIYOFUMI
IPC: H01S5/343
Filed: 1995-10-16
Abstract: The present invention is directed to a semiconductor laser device comprising, as shown in Fig. 1, on a buffer layer 32 of n-GaAs, a clad layer 31, a wave guide layer 30 and a carrier block layer 29 of n-AlGaAs, a side barrier layer 28 of non-doped AlGaAs, an active layer 27 which is formed by two non-doped GaAs quantum well layers and a barrier layer of AlGaAs, a side barrier layer 26 of non-doped AlGaAs, a carrier block layer 25, a wave guide layer 23 and a clad layer 22 of p-AlGaAs, and a cap layer 21 of p-GaAs in this order. Inside the wave guide layer 23, current narrowing layers 24 having a lower refractive index and higher A1-composition than that of the wave guide layer are formed to sandwich a stripe-shaped active region 34. This creates a refractive index difference between the active region 34 and buried regions 33 in which each of the current narrowing layers 24 exists, thereby forming a refractive index guide structure. Thus, it is possible to obtain a high-output semiconductor laser device of the refractive index guided type which is easy to manufacture.

Title: Device for aerosolizing narcotics
Inventor: SCHUSTER JEFFREY A
IPC: A61M16/00
Filed: 1995-10-27
Abstract: Devices are hand-held, self-contained units which are automatically actuated at the same release point in a patient's inspiratory flow cycle. Actuation of the device forces an algesic formulation (5) through a porous membrane (3) of the container (1) which membrane has pores having a diameter in the range of about 0.25 microns to 1.5 microns. The porous membrane is positioned in alignment with a surface of a channel (11) through which a patient inhales air. The flow profile of air moving through the channel is such that the flow at the surface of the channel is less than the flow rate at the center of the channel. The membrane is designed so that it protrudes outward at all times or made flexible so that when an analgesic formulation is forced against and through the membrane, the flexible membrane protrudes outward beyond the flow boundary layer (13) of the channel into faster moving air.

Title: Project dark mansion
Inventor: CHAMBERS ROBERT M
IPC: G06F9/44
Filed: 1997-06-02
Abstract: This invention remedies the computer application problem where a two digit year is used in calculations across century boundaries. Where the problem exists 03 minus 97 yields -94 rather than 2003 minus 1997 correctly yielding 6. This technique applies a series of comparisons within a centralized date calculation module to add the century portion to the year. This means minimal modification to computer programs and no requirement to change databases, files, screens, reports or storage structures. This technique can translate one date format to another. It can also alter files for use by other systems to accommodate variations in date formats. It handles most common date formats and storage strategies and includes the facility to locate existing datecalculations so substitutions can be made.
