Inventor: MURAKAMI YOSHITERU
IPC: G11B11/105
Filed: 1991-05-02
Abstract: A magneto-optical disk has a substrate whereon a recording medium is formed, and a depression is formed on the substrate on the inside of the recording medium of the substrate. A center hub is installed on the depression such that the center hub is substantially level with a protective- resin layer covering the recording medium. On the center hub, a flying head performs CSS (Contact-Start-and-Stop). This configuration of the disk eliminates the occurrence of dust due to abrasion and head crash, and achieves stable CSS. A method of manufacturing the magneto-optical disk is also disclosed, wherein the protective-resin layer is formed after installing the center hub on the depression. In this method, since a space is not produced between the center hub and the protective-resin layer, stable flying characteristics are obtained. And a magneto-optical disk is disclosed, whereon small physical bumps and pits are formed on the substrate on the inside of the recording medium, which prevents the flying head from sticking to the disk. A method of manufacturing the magneto-optical disk by using a stamper, which permits the disk to be mass-produced, is also disclosed.

Abstract: A box spring assembly in which the support springs are designed so as to permit spring location independent of long wire location in the support deck.  The mattress support deck is suspended on support springs which are interwoven and self-secured on crosswires  so as to eliminate the need of retaining clips in the assembly.  The mattress support deck is inhibited in its lateral motion by support springs disposed therein in an interference relation with the long wires of the support deck.  So constructed,  a manufacturer is enabled to distribute the support springs as required and desired on the frame regardless of the position of the long wires.

Title: Apparatus and method for minimizing differential thermal expansion of gas turbine vane structures
Inventor: HULTGREN KENT G
IPC: F01D5/18
Filed: 1991-09-09
Abstract: 18                       56,075 ABSTRACT OF THE DISCLOSURE An apparatus and method are provided for minimizing differential thermal expansion in external cooling air structures formed on the shrouds of the vane segments Or a gas turbine.  The external cooling air structure is formed from a laminate comprised of two layers joined in sandwich-like fashion.  A passageway, which may be of a serpentine arrangement, is formed between the two layers of the laminate.  Hot gas flowing over the shroud is directed through the passageway, thereby heating the structure 50 that its temperature is close to that of the shroud.  Cooling air is bled into the hot gas directed to the passageway so as to reduce the temperature of the hot gas flowing through the passageway and prevent overheating of the external cooling air structure.

Abstract: In order to enable/disable message receipt in a radio pager, a radio transmission is received which is comprised of a pager address code and a message signal which includes a set of control codes.  Following this, the pager address code is compared with a predetermined pager ID code.  In the event that the pager address code coincides with the pager ID code, the message signal is acquired.  Subsequently, it is checked to see if the control code set is present within the message signal. In the event of a positive outcome in the above mentioned checking, the control code set is extracted from the message signal.  Then, a piece of message receive control data stored in the pager is rewritten which determines if the message signal is displayed or disregarded.

Patent CA-2078426-A1 (CA)
Inventor: CASTELLI VITTORIO R
IPC: G03G21/00
Filed: 1992-09-16
Abstract: A belt receptor module for a color printer isolates disturbances such as impulsive and high-frequency force disturbances caused by entrance of a recording medium into a transfer nip of a transfer station.  The belt receptor module includes a belt receptor positioned about a plurality of spaced rollers.  A transfer station is located adjacent an area of the belt receptor.  A tension roller is located adjacent the belt receptor on either side of the transfer station.  The tension rollers each articulate about an appropriate axis to enable the belt receptor to enter a subsequent roller at an angle of approximately 90° to its axis without generating lateral forces.  Each tension roller is movable along a different line to create a tension level therein, each tension level being different from the other tension level.  The tension levels generated by the tension rollers do not substantially change with the position of said rollers and, thus, providerelief from the impulsive and high-frequency force disturbance caused by the entrance of a recording medium into a transfer nip of the transfer station.  Theisolation of the disturbance enables proper registration of the color separations while avoiding motion-induced artifacts.

Inventor: BURGES CHRISTOPHER J
IPC: G06V30/10
Filed: 1992-11-24
Abstract: Apparatus and processes are described for the automatic recognition of alphanumeric images. A set of cuts are made to the image which include incorrectsegmentations. The resulting "cells" comprising in their totality the created segments of the image are then analyzed to determine which cells are legal neighbors and which are not. All cells which are legal neighbors are then presented as connected nodes. A pruning of nodes which are related to certain predetermined image cuts is effected. Each set of remaining connected nodes is then presented to a recognizer which identifies the image and assigns a specified probability to theoutput. Many cells which are not legal neighbors are thereby not presented to the recognizer, thus saving substantially on computations per recognized image.

Title: Solid-phase precipitation assay device and method
Inventor: JONES RONALD M
IPC: G01N33/92
Filed: 1991-07-15
Abstract: An assay device (14) for measuring the concentration of a soluble analyte, such as HDL-associated cholesterol, in a fluid sample containing interfering compounds, such as LDL- or VLDL-associated cholesterol, which can be selectively precipitated. The device includes a sieving matrix (26) capable of separating soluble and precipitated material migrating through the matrix, and a reservoir (34) which holds a precipitating agent which is effective, within a given concentration range, to selectively precipitate the interfering compounds. The reservoir is designed to delay the release of agent, on contact with the fluid sample, to maintain the concentration of precipitating agent in contact with the fluid sample within the given concentration range. The device additionally includes an assay pad (64, 66, 68, 70) in which the soluble analyte present in the fluid sample can be assayed. A method of separating high-density lipoproteins (HDL) from low- and very-low-density lipoproteins (LDL and VLDL) employs a coated glass fiber matrix which inhibits binding of HDL as a blood fluid sample containing HDL and precipitated LDL and VLDL passes through the matrix. <IMAGE>

Title: Method and device for reducing the driving power for an hydraulic lift
Inventor: NAGEL HEINZ-DIETER
IPC: B66B9/04
Filed: 1993-01-15
Abstract: SUMMARY:     The invention concerns a method and a device for reducing the driving power for an hydraulic lift, in which an energy-saving drive is realised by an advantageous combination of different equipments.  The lift cage (1) is suspended in the shaft (7) by an in itself known cable deflection in the ratio of 4:2 and connected with an hydraulic piston-cylinder unit (10).  A counterweight system in the ratio of 2:1 is arranged at the head end (16) of the piston cylinder unit (10) in order that the required pressure force at the piston can be reduced.  The counterweight (23) is so designed that the weight of the cage and the foreseeably most frequently arising load in the cage are balanced out.  The cylinder (11) of the piston-cylinder unit (10) is charged by the pump for the upward travel as well also for the downward travel of the lift cage (1), wherein a differential circulation of the fluid currents take place for the upward travel, whereby a smaller fluid volume can be used for the dimensioning of the pump.
