Title: Metal coated optical fiber array module
Inventor: RHEE TAE-HYUNG
IPC: G02B6/36
Filed: 1998-08-26
Abstract: A metal coated optical fiber array module including a metal coated optical fiber array, an arranging substrate having arranging grooves for loading the optical fiber array, wherein a metal is coated on the upper surface including the arranging grooves and the optical fiber array loaded into the arranging grooves is united therewith through the medium of the metal, and a cover for protecting and fixingthe optical fiber array loaded into the arranging grooves of the arranging substrate. It is preferable that the optical fiber array module further includes a planar substrate having holes into which the optical fiber array is to be inserted, wherein the optical fiber array loaded on the arranging substrate is inserted into the holes and united with the arranging substrate. After the optical fibers are loaded, the ends thereof are easily polished. When the optical fibers are attached to a waveguide device, the ends of the arrayed optical fibers are enlarged to increase an attachment strength at the contact surface. The axes of the optical fibers are prevented from being tilted, by ultraviolet (UV) irradiation upon loading the optical fibers. Also, when the optical waveguide device is attached to a multi-core optical fiber, a contact surface is widened, thus improving environmental characteristics and reliability of a device package upon connection of the optical fibers.

Title: Transdermal therapeutic system with small application-area thickness and great flexibility, and production process
Inventor: VON KLEINSORGEN BRITTA
IPC: A61K9/70
Filed: 1997-03-12
Abstract: A transdermal therapeutic system to release active agents to a substrate is characterised by the composition of the system of a substrate (1) bearing a separating layer (2), a film (3) containing the active agent and a releasecoated protective layer (4), in which the separating layer (2) consists of a material, the bond of which to the film (3) can be released. Such systems can be produced by printing technology to have small thickness and great flexibility, where the substrate/separation layer complex may be replaced by a release-coated substrate. Problems of disposal are reduced by a printing process restricting the active agent-containing region to the application area.

Title: Non-invasive monitoring of hemodynamic parameters using impedance cardiography
Inventor: MOROZOV ALEKSANDR A
IPC: A61B5/296
Filed: 1997-04-07
Abstract: A method and apparatus for determination of heart rate, heart stroke volume, and cardiac output from thoracic bioimpedance signals and electrocardiograms. A unique bioimpedance electrode arrangement is employed, and the bioimpedance signals are corrected for gain phase-frequency distortion through the use of sinusoidal test signals through the measuring or detection electrodes to identify distortions and correct for same during actual measurements. Time-derivative bioimpedance signals are employed, the power spectrum calculated, and a novel autoconvolution procedure used to emphasize the heart rate harmonic. Breath waves and other signals not indicative of the patient's cardiocycles are removed. Left ventricular ejection time is derived from the bioimpedance signals, and an improved version of Kubicek's equation is employed to derive heart stroke volume and thus cardiac output.

IPC: G06F13/00
Filed: 1997-04-11
Abstract: A recompression server (20) that automatically decompresses selected pre-compressed data streams and recompresses the decompressed data to a greater degree than the original pre-compressed data. In one embodiment, the recompression server (20) determines from a request whether a requested file is pre-compressed. In another embodiment, the recompression server (20) determines from a retrieved requested file's name or attributes whether the file is pre-compressed. Optionally, the recompression server (20) may cache frequently requested files in re-compressed form to further optimize the bandwidth of a wide area network (8). Such caching can be done on-line or off-line.

Title: Disk recording or playback device and method of adjusting initial position of pickup thereof
Inventor: OGATA HITOSHI
IPC: G11B7/085
Filed: 1998-11-12
Abstract: A disk recording or playback device has mounted on a chassis a pickup for detecting addresses on a disk, and a sensor switch SW for detecting the pickup as brought to the inner peripheral side of the disk. The pickup is moved toward a lead-in area of the disk to turn on the switch SW, thereafter reversely moved and caused to overrun for a predetermined period of time from a position where the switch SW is turned off . The pickup reads an address on the disk and is thereafter returned. When the address is outside a target region within the lead-in area, the pickup is repeatedly moved toward the lead-in area again with the overrun time altered. The overrun time is stored which enables the pickup to read an address within the target region upon overrunning.

Title: Process for conditioning of surfactant pastes to form high active surfactant agglomerates
Inventor: HAILU LIBEN
IPC: C11D17/06
Filed: 1997-06-27
Abstract: The invention provides an effective process for conditioning pastes comprising at least 40 % by weight of anionic surfactant. The paste is conditioned by mixing alkyl sulphate powder with the surfactant paste in a ratio of at least 1 part powder to 100 parts paste. This conditioning step increases the viscosity of the surfactant paste. The conditioned paste is processed into agglomerates by granulating with builder powders wherein the ratio of high viscosity paste to builder powder is from 9:1 to 1:5. This process enables detergent agglomerates with high surfactant activity to be formed.

Abstract: A bonus game for a slot machine operable in a basic mode and a bonus mode. The bonus game is entered upon the occurrence of a special start-bonus game outcome in the basic mode. In the bonus game, a player selects, one at a time, from an array of windows each associated with a bonus game outcome. Credits are awarded based upon which ones of the windows are selected. The bonus game ends upon selection of a window associated with an end-bonus outcome but otherwise continues, allowing the player to make further selections and accumulate further credits until encountering an end-bonus outcome. In one embodiment, a bonus game resource obtained in the basic game may be exercised in the bonus game to affect the bonus game outcome. In one embodiment, for example, where the occurrence of an end-bonus outcome would otherwise end the bonus game, a player having a bonus game resource may exercise the bonus game resource upon encountering an end-bonus outcome to continue playing the bonus game.
