Abstract: The invention relates to a hinge connection (2) which functions to connect a first structural part (A) or panel with a second structural part (B) or panel such that the two structural parts can pivot in relation to one another. The hinge connection includes a first hinge member (3a) which is attached to the first structural part (1) and a second hinge member (4a) which is attached to the second structural part (1a'), and a band (3', 4') which extends between the hinge members, such as to form a hinge element. A first hinge element (3) is intended to coact with one side part (1') of the first structural part (1) and the second side part (1a") of the second structural part (1a), whereas a second hinge element (4) is intended to coact with the one side part (1a') of the second structural part (1a) and the second side part (1") of the first structural part (1). The band (3', 4') of the hinge element can be stretched to an adapted tension through the intermediary of one of the hinge members (3a, 3b, 4a, 4b).

Title: Hardware protection control for computer storage devices
Inventor: ELLIOTT THOMAS E
IPC: G06F21/80
Filed: 1993-03-11
Granted: 2001-04-24
Abstract: A write protect device for a computer comprising a hardware circuit with a switch connected to an internally installed circuit card which has cable connections between data storage device drives and a drive controller cable, the circuit card intercepting control lines used for drive selection and control. The switch is connected to inputs of a latch circuit which, in one position of the switch, generates *READONLY and READONLY signals at outputs of the latch circuit and *DISABLE and DISABLE signals at other outputs when the switch is placed in a second position. The circuit card includes an inverter and a NAND gate in a *WRITE GATE line to the data storage device drives with one input of the NAND gate being connected to the *READONLY line from the latch circuit which will prevent any *WRITE GATE signal from reaching the data storage device drives when the *READ ONLY line is activated to place the computer in a read only mode. A further inverter and a NAND gate intercepts a *DRIVE SEL line to the data storage device drives with the NAND gate having one input connected to the *DISABLE line from the latch circuit. When the *DISABLE line is activated, that NAND gate will prevent any *DRIVE SEL signal from reaching an associated data storage device drive and place the computer in a drive protected mode. A number of internal optional links and NAND gates on the circuit card can create further selectable operational features for the computer such as an object reuse feature which, when enabled, will prevent any changes in the switch position from changing an operational mode until after the computer is "reset".

Title: Mold for synthetic resin molding
Inventor: KATAOKA HIROSHI
IPC: B29C33/56
Filed: 1992-09-25
Granted: 1997-07-01
Abstract: It has been conventionally considered difficult to adhere a mold metal and a polyimide, etc. whose coefficients of thermal expansion differ from each other by one figure and to retain the adhesion in injection molding, etc. involving severe heating-cooling cycles over several tens of thousands of times. The greatest merit of injection molding resides in that a molded article of complicated shape can be obtained through one shot. It has been demanded to obtain a mirror-smooth injection molded article with good molding surface reproduction without extending the mold-cooling time while retaining this merit. The present invention provides a mold satisfying both of the durability and the demand. The present invention relates to a mold for synthetic resin molding comprising a mold body made of a metal having a heat conductivity of not less than 0.05 cal/cm temperature having provided on the cavity wall thereof a polyimide layer, characterized in that said polyimide layer has a thickness of from 0.02 to 2 mm, has a heat conductivity of not more than 0.002 cal/cm temperature of not less than 200.degree.C, has been formed by coating a solution of a precursor of a linear high-molecular weight polyimide on the cavity wall followed by heating, has an elongation at break of not less than 10%, and has an adhesive strength of not less than 500 g/10 mm to the cavity wall.

Abstract: Connectors for electrical components include a support base having an edge which defines an open space, and an electrically insulated socket member connected to the support base within the defined open space for holding and establishing electrical connection with the electrical component. The socket member includes opposed pair of side walls, an upper wall and a lower wall which collectively establish an open ended interior space. At least one clamp connector is disposed in a rearward end of the interior space and is coupled to the socket member for receiving a terminal portion of an electrical component inserted into forward end of the interior space so as to connect the electrical component electrically to an external circuit. Opposed pairs of separated upper and lower locking tabs are formed on either the side walls of said socket member or the support base, and project outwardly therefrom. These upper and lower locking tabs serve to connect the socket memberto the support base and positionally restrain the socket member within the defied space. Preferably, the edge of the support base defines an enlarged forward space in which the electrical component is disposed, and a rearward space in which the socket member is disposed. In this regard, the support base will most preferably include inwardly projecting retaining ears disposed at a juncture between the forward and rearward spaces.

Abstract: A method of automatically determining the reliability of any LOS radio link given certain parameters. Specifically, this method allows a communications network operator to specify and determine the path reliability (PR) for each backbone and extension link in a communications network for a given operating frequency, path length and climatic factor. For each link, the fade margin required (RFM) for a desired path reliability (PRD) is calculated. Then, the actual fade margin of the selected link is calculated using known radio parameters. Preferably, these known radio parameters are stored in a database to facilitate access to this information. Then, the corresponding value of the actual path reliability far the link is calculated using modifications of known statistical models which take into account climatic and geographic factors.

Abstract: The invention relates to a method for manufacturing a sheet metal tool that is not planar, and the tools made from the method. A sheet metal blank has a predetermined design of etching resistant material applied to one surface to define exposed areas separated by resist areas. A layer of etching resistant material is also applied to a second surface of the metal blank which overlies at least the exposed areas on the first surface of the metal blank. The exposed areas on the first surface are then subjected to etchant applied from the first surface of the metal blank through the exposed areas to form a tooth shape with a cutting edge. The formed cutting edge terminates in a sharpened surface in the second surface, protected by the layer of the etching resistant material on the second surface of the metal blank.

Abstract: A roof panel attachment clip includes a bracket having an upper flange, and a sliding member which supports one or more tabs.  The sliding member and the bracket have alignable openings such as slots above a hole for receiving a bolt which connects the bracket to a purlin.  The openings are sized to receive the shaft of an installation tool, such as a socket wrench, and must be aligned in order to get the wrench proper-ly on the fastener.  The installer is thus assisted in center-ing the tabs in the slots as he connects the bracket to the purlin.  Once the tool is withdrawn, it is possible to slide the tabs out of position, but a biasing force between the sliding member and the bracket resists such movement.
