Abstract: A monolithic multilayer ultra thin chip inductor (10) is manufactured with two terminals (12) and (14) on the same end of the component (10) to reduce the mechanical stresses caused by a coefficient of expansion mismatch. A third no-connect terminal (16) located on the opposite end may be used to mount the component (10) when a more rigid connection is required. The inductor is constructed using a bottom and top coil layer (18) and (40), each having a coil and forming a termination point corresponding to the inductor terminals.      The opposite ends of the coils form connection ends (24) and (68) and are electrically connected to form a continuous coil from one terminal (12) to the other (14). Optionally, a number of intermediate coil layers (28) can be included between the bottom and top coil layers (18) and (40). The coil layers are selected from a set of coil layers. As a result, the total number of coil turns can be obtained by selecting the appropriate coil layers.

Title: Safety equipment for multimobile lift groups
Inventor: CHENAIS PATRICK
IPC: B66B5/00
Filed: 1996-10-16
Granted: 2005-08-02
Abstract: With this safety equipment in a multimobile lift group, collisions between cages (C1..CN) operating in the same shaft (1) can be prevented. For this purpose, each cage (C1..CN) is equipped with a safety module (10). In order not to cause any collision in the case of a stop command of a cage (C1..CN), the safety module (10) must know the positions and speeds of the other cages (C1..CN) at all times. A decision module (12) integrated into the safety module (10) processes the travel data received by way of the communications system (11) and decides whether a cage (C1..CN) may or may not stop. Furthermore, the decision module (12) determines the braking behaviour of a cage (C1..CN) (normal stop, emergency stop or triggering of the cage-catching device).

Abstract: A table (10) is provided to assist in the manufacture of building structures such as walls and the like, where the walls comprise a plurality of studs (60) extending between top and bottom members (14, 16). The table (10) comprises a support surface (12) for supporting the top and bottom members (14, 16) of the wall. In particular, the table (10) is most useful in manufacturing walls of steel studs. The table includes grasping means to grasp the building structure to be able to move the structure along the support surface (12) of the table (10). A computer operated controller controls motors to locate the top and bottom framing members as desired along the table and to locate the top and bottom framing members at desired locations adjacent assembly stations (50, 52). The assembly stations (50, 52) are used to attach a stud (60) to each of the top and bottom members (14, 16). The assembly stations are mounted on tracks and the location of the assembly stations along the track is controlled by a servo motor under control from the controller. The assembly stations may move transverse to the top and bottom framing members. The assembly stations are also movable in a vertical plane so as to be movable below the support plane of the table and to be movable to a plane to form connections. The assembly stations are also pivotable about a vertical axis. By X direction movement of the top and bottom members, Y direction movement of the assembly stations, height adjustable movement of the assembly stations and pivoting of the assembly stations about a vertical axis, the assembly stations can be moved to attach studs facing in either direction or cripple studs to top and bottom members or headers to studs and cripple studs to headers or any combination. Preferably the assembly stations create button type joints by working metal of the top or bottom members and metal of the studs to form buttons. The assembly stations include punches and anvils which may be moved within a stud to form multiple buttons on each flange of a stud simultaneously with internal support for the two anvils.

Title: Improvements in the in situ pcr
Inventor: BLOCH WILL
IPC: C12Q1/68
Filed: 1992-07-20
Granted: 2000-11-07
Abstract: Improvements to the in situ polymerase chain reaction (PCR), a process of in vitro enzymatic amplification of specific nucleic acid sequences within the cells where they originate, can be achieved by changing the way that the enzymatic reaction is started. Reaction initiation is delayed until the start ofPCR thermal cycling, either by withholding a subset of PCR reagents from the cellular preparation until the preparation has been heated to 50° to 80° C, immediately before thermal cycling is begun, or by adding to the PCR reagents a single-stranded DNA binding protein which blocks reaction at temperatures below about 50°C. If the in situ PCR is performed on cellular preparations already attached to a microscope slide, thermal cycling also is facilitated by use of a thermal cycler sample block or compartment designed optimally to hold the microscope slide and any vapor barrier covering the slide.

Abstract: The invention relates to a cavity constituted by a casing of a gas turbine and a moving blade with a tip shroud,  by which a cavity space is made to a necessary minimum size, a main flow gas is prevented from being entrained and a pressure loss is reduced.  A tip shroud (6) is mounted on a tip end portion of a moving blade (4), a fin (7) is mounted thereon,  a recess-like cavity (15)  narrower than the conventional one is formed by portions (12a) and (12b) of a casing (12) and the fin (7), and further a projecting portion (16) is provided to an upstream end portion of the tip shroud (6).  The projecting portion (16)  is at a position (13a) at a time of a cold start and is at a position (13b) at a time of a hot start run, even if a thermal expansion occurs,  thus the projecting portion (16) is not in contact with the recess portion,  a main flow gas (1) is less entrained within the cavity (15), and a pressure loss is reduced because of no swirl,  so that a performance of the gas turbine is enhanced.

IPC: B29C48/94
Filed: 1996-09-20
Granted: 2007-01-02
Abstract: The invention relates to an extruder with which material is extruded through a tool (2). Fluoropolymer is used between the extrusion material and the tool (2) for reducing friction between the material and the tool. At least the surface of the tool (2) against fluoropolymer is if a material whose thermal conductivity is greater than the thermal conductivity of ordinary tool steel. Therefore the friction heat generated can be conducted efficiently away from the interface between the tool (2) and the extrusion material towards the tool (2), whereby the wear of fluoropolymer can be reduced and thus the durability of the tool (2) can be improved. In that case the extrusion product will slip evenly out from the tool (2), whereby the surface of the product is essentially smooth without transverse microscopic stripes repeated at a specific wave length.
