Filed: 1989-01-11
Abstract: An induction-hardening machine for the contour hardening of machine components such as gears includes a machine with both high-frequency and low-frequency induction generators operably arranged with corresponding induction coils positioned at a machine workstation and interfacing with computer controls. The high-frequency and low-frequency coils are arranged in a substantially concentric fashion such that the part to be induction hardened may be moved axially from one induction coil to the other depending upon the selected induction hardening process. The computer controls include a microprocessor operable to receive a computer disk which is formatted with specific machine settings and parameters for the automatic running and induction hardening of the particular part. The induction coils and the machine settings on the computer disk are all generated from a computer algorithm consisting of a series of equations and formulae which treat specific part characteristics and parameters so as to define the optimum coils and settings for induction hardening of that particular part.

Abstract: A differential amplifier coupled between sources of a high supply voltage (V HH ) and a low supply voltage (V LL ) contains a pair of differential portions (30 and 32), that are used to amplify a differential input signal (V I1  and V I2 ). One of the differential portions is turned on when the common-mode voltage of the input signal is in a portion of the supply range extending up to the high supply voltage. The other is turned on when the input common-mode voltage is in a portion of the supply range extending down to the low supply voltage. A level-shift circuit (38, 40, 42, 44, and 46) selectively raises or lowers the voltages at input points (P1, P2, P3, and P4) to the differential portions. The level shifts extend the conductive ranges of the differential portions. This enables the amplifier to eahcieve rail-to-rail input capability down to 1 volt or slightlty less for the power supply voltage.

Abstract: A pair of wiper blades (11,14) on a vehicle window (10) are oscillated in opposing movement from an overlapping inner wipe arrangement, with upper and lower overlapped blades, outward to separated outer wipe positions (31,36) and inward to the overlapping inner wipe arrangement with the positions of the wiper blades reversed. Since the upper wiper blade on the way out becomes the lower wiper blade on the way back, it does not need to pause in its outer wipe position and it thus does not need to be subjected to a large acceleration in maintaining fast wipe cycles on large vehicle windshields. This reduces stress on the wiper arm (12,15) and blade and blade end whip.

Abstract: This invention provides a brushless DC motor which does not have a position sensor for detecting a rotational point of a rotor. Instead of using a position sensor, zero-crossing points of counter electromotive forces induced in the stator windings of the rotor are detected to obtain a pulse signal train. From the pulse signal train thus obtained and a slant waveform signal generated in response to the pulse signal train, a position signal with a trapezoidal waveform is formed. An electric current signal with a trapezoidal waveform is supplied to the stator windings of the rotor in response to the position signal thus formed for effecting an electric current switching of the stator windings smoothly, resulting in realizing a motor drive less in vibration and noise even when rotating at a high speed.

Abstract: The invention relates to a charge-coupled device which has two or more parallel channels provided with a demultiplexer by which a series of consecutive signals is distributed over the parallel channels. For each signal, a given number of charge packages is formed, corresponding in size to the input signal, of which only one is stored in the relevant channel while the remaining charge packages are drained off. This method of demultiplexing imposes no or at leat substantially no speed limitations on the device, which as a result is particularly suitable as a memory or delay line for very high frequency signals, for example, of 1 GHz. In a particular embodiment, the charge-coupled device is of the buried channel type with an npn (or pnp) structure in which the charge packages are drained off through the substrate.

Abstract: An antibody raised to type I collagen carboxyterminal cross-linked telopeptide isolated from decalcified human or animal bone, may be used in an assay to determine the concentration of liberated carboxyterminal telopeptide region of the type I collagen molecule in a sample. When the sample is a body fluid such as serum or urine the degradation product measured is resistant to further degradation, since it contains a multivalent intermolecular cross-link, and can thus be found in the body fluid. The assay may be used to assess the degradation of type I collagen, the major organic constituent of bone matrix.

Abstract: A facility is provided for storing in a backup memory (30-1-P) only those blocks of a file, or disk partition, which differ from corresponding blocks forming an earlier version of the file. Specifically, a file is divided into a number of blocks and a "signature" is generated for each such block. A block is then stored in the backup memory only if its associated signature differs from a signature generated for an earlier version of the block. In addition, if two blocks of the current version of the file have identical signatures and are to be stored in the backup memory, then only one of the two blocks is stored in the memory and a simple message indicating that the other block is equal to the one block is stored in the memory for the other block. Further, the application of such signatures is advantageously applied to the opposite case of restoring a file using copies of previous versions of the file that are stored in the backup memory.

Abstract: A multi-processor computer system executes a single-thread program having a plurality of callable procedures in program modules. The local memory of each processor contains a program stack, the object code of each module that executes on that processor, and an agent object and data structures containing linkage information. In addition, the local memory contains a c-stub module for each procedure executable on a different processor, and a s-stub module for each procedure in local memory that can be called by a procedure executing on another processor. When a procedure X executing on processor I wishes to call a procedure Y which executes in processor II, it issues a local call to Y's c-stub in processor I's local memory. The Y c-stub then invokes the agent process in processor I, which communicates with a corresponding agent process in processor II. The agent process in processor II causes a Y's s-stub in processor II to issue a local call to procedure Y. The return from a procedure follows the same path in reverse. Each processor independently maintains its own version of the program stack, with stack entries referencing the locally executable procedures, local stubs, or local agents. With each local call or return, the program stack for that processor is updated appropriately. Because each processor independently maintains its own stack, remote procedure calls are not constrained by the past calling history of a process. A procedure X in processor I may call a procedure Y in processor II, which may in turn call another procedure Z in-processor I. It is therefore possible for a conventional single-thread program to be converted to operation on a multi-processor system without any significant modification to the source code.

Abstract: A waveguide antenna (1) has an upper (2) and a lower (3) cavity waveguide, these waveguides being separated by a partition wall (4). Transversely extending slots (7) are disposed along the centre line of the upper waveguide (2) with a mutual spacing of one wavelength-distance (λ g ). Two slots (6) which extend in the direction of the longitudinal axis of the waveguide are disposed between the transversal slots (7). The partition wall (4) is provided with longitudinally extending slots (8) immediately beneath the longitudinally extending slots (6), and field-shifting posts (9) are placed in the lower waveguide (3) adjacent the latter slots (8) in a zig-zag pattern along the waveguide (3). Baffles (10) counteract grating lobes. A fundamental mode of an electromagnetic field (E1) in the upper waveguide (2) excites only the transversal slots (7), which radiate a field (E3). The same fundamental mode (E2) in the lower waveguide (3) excites the slots (8) in the partition wall. These latter slots radiate a field (E4) which excites only the upper longitudinally extending slots (6), which radiate a field (E5). Supply of the fundamental modes (E1, E2) and also the radiated fields (E3, E5) are independent of one another and a desired polarization can be obtained. A radiated lobe is symmetric and the radiated fields (E3, E5) can carry individual information.
