Title: Optical information recording device and method
Inventor: NODA KAZUO
IPC: G11B7/131
Filed: 1995-08-15
Granted: 1999-02-23
Abstract: A laser light beam generated from a light source is divided by a diffraction grating into a plurality of light beams, i.e., a single main beam to be used for recording information and plural auxiliary beams distributed on two imaginary straight lines crossing each other.   One of the straight lines extends parallel to tracks of a recording medium.   The resultant divided beams are converged to be irradiated onto a recording medium, and reflected components, from the recording medium,  of the beams are received by corresponding light receiving elements.  Thus, the main and auxiliary beams distributed on one of the two imaginary straight lines are used to perform focusing and tracking.          Further, one of the two auxiliary beams distributed on the other straight line are used to determine whether a track where information is to be recorded is a blank area or not, and the other of the auxiliary beams is used to verify whether the information has been recorded correctly.

Abstract: Apparatus and method are provided for determining the concentration of an analyte in a fluid test sample by applying the fluid test sample to the surface of a work- ing electrode which is electrochemically connected to a reference electrode which surface bears a composition comprising an enzyme specific for the analyte. A media- tor is reduced in response to a reaction between the ana- lyte and the enzyme. An oxidizing potential is applied between the electrodes to return at least a portion of the mediator back to its oxidized form before determining the concentration of the analyte to thereby increase the accuracy of the analyte determination. Following this initially applied potential, the circuit is switched to an open circuit or to a potential that substantially re- duces the current to minimize the rate of electrochemical potential at the working electrode. A second potential is applied between the electrodes and the current gener- ated in the fluid test sample is measured to determine analyte concentration. Optionally, the accuracy of the analyte determination is further enhanced algorithmi- cally.

Title: An electronic trading method
Inventor: TERAMURA TAKESHI
IPC: G06Q30/04
Filed: 1997-11-18
Granted: 2002-06-11
Abstract: An electronic trading method prevents unjust trading relative to prices or goods in an electronic trading using valuable data such as electronic money as settlement means.  A broker server which temporarily stores electronic money, for example, is connected to a communication network.  When electronic money is sent as a price of goods from a terminal of a goods consumer to a server of a goods merchant, the sending of electronic money is performed in two steps including sending of electronic money from the terminal of the consumer to the broker server and sending of electronic money from the broker server to the server of the merchant.  The sending of electronic money from the broker server to the server of the merchant is performed when a predetermined settlement condition including a condition relative to the elapse of a designated date or reception of a receipt issued by the terminal of the consumer is brought into existence.  When the consumer does not receive goods although a predetermined delivery date of goods has elapsed, the terminal of the consumer transmits a command for prohibiting settlement to the broker server.  When the broker server receives the command, the broker server does not sent electronic money to the server of the merchant even if the settlement condition is brought into existence.

Title: Intrastromal photo-refractive keratectomy
Inventor: JUHASZ TIBOR
IPC: A61B18/20
Filed: 1998-02-16
Granted: 2009-05-05
Abstract: A method for performing intrastromal photorefractive keratectomy in the cornea of an eye, using a pulsed laser beam, includes the initial step of focusing the beam to a focal spot at a selected starting point in the stroma. The starting point is located at a predetermined distance behind the epithelium of the cornea. While focused on the starting point, the laser beam is pulsed to disrupt a volume of stromal tissue which is substantially equal to the volume of the focal spot. Subsequently, the beam is focused in a patterned sequence to focal spots at other discrete points in the stroma. At each point the stromal tissue is photodisrupted. With this progressive pattern of photodisruption, each spot is placed substantially adjacent a volume of previously disrupted tissue. The resultant photodisrupted tissue creates a layer which is substantially centro-symmetrical around the optical axis. A plurality of layers can be removed to create a cavity in the stroma. When the cavity collapses, the corneal curvature is changed as desired.

Abstract: A slide driving device employs a variable-displacement pump/motor for driving a rotating element of the slide driving device. The displacement volume of the variable-displacement pump/motor, whose output drives the slide, is varied in response to deviation of measured driver parameters from commanded driver parameters. An energy storage device temporarily absorbs excess energy during a portion of a molding cycle, and returns the energy to the system for reuse. In one embodiment, the energy storage device is an accumulator. In a second embodiment, the energy storage device is a flywheel. The combination of variable displacement volume and energy storage maintains the fluid pressure substantially constant during a cycle of the slide driving device.

Abstract: Lorsqu'on garnit des boîtes en carton monobloc dans un cadre de congélation, il faut faire attention à ce que les rabats de coin (20, 27) de la boîte en carton soient situés à l'extérieur des parois latérales adjacentes (8), afin d'éviter qu'ils ne pénètrent dans la matière à congeler placée dans le cadre de congélation garni. Lors de l'assemblage rapide du carton monobloc, il peut s'avérer difficile de voir si les rabats de coin sont situés à l'intérieur ou à l'extérieur des parois latérales adjacentes du carton, étant donné qu'ils se confondent au milieu ambiant. L'invention permet de remédier à cette situation. Ainsi, les côtés intérieurs des rabats en coin (20, 27) portent une marque distinctive, par exemple une couleur différente, qui ressort de manière tellement évidente du reste de l'intérieur de la boîte en carton, que l'on repère immédiatement la mauvaise position des rabats en coin.
