Abstract: A digital oscilloscope has a vertical amplifier for adjustably offsetting and amplifying an input signal and a digitizer for digitizing the amplifier output signal after it reaches an adjustable trigger level to provide a data sequence controlling a waveform display on a screen. The oscilloscope includes a computer automatically adjusting trigger level, vertical gain, vertical offset, and digitizing frequency to provide a waveform display representing the amplifier output signal. The computer adjusts the trigger level while monitoring digitizer output to measure minimum and maximum peaks of the amplifier output signal and sets the trigger level between the measured peaks. The computer then iteratively adjusts amplifier gain and offset until it determines that a waveform display controlled by the digitizer output would have minimum and maximum peaks vertically separated by a substantial distance on the oscilloscope screen. The computer estimates the period of the input signal from the digitizer output sequence and adjusts digitizing frequency so that the digitizer output sequence represents a few cycles of the amplifier output signal.

Abstract: An electrofusion method in which an electrofusion joint having an electrical heating wire (11) embedded in the inner peripheral region thereof is fitted on or laterally pressed against an end of a resin pipe and electrical currentis supplied to the electrical resistance heating wire so as to melt and fuse the electrofusion joint. The joint is beforehand provided with an annular groove formed in the outer peripheral surface of the joint to reach a region near the electrical resistance heating wire. The annular groove defines a pin- or bar-like core which serves as a pressure-transmitting member such that any rise in the pressure due to fusion of the joint is detected by a pressure switch through the core, and the supply of the electrical current is terminated in response to detection of the pressure by the pressure switch through the core. 
     Disclosed also is a method of confirming the state of fusion of an electrofusion joint in which the joint is beforehand provided with a detection hole (14) formed in the outer peripheral surface of the joint to reach a region near the electrical resistance heating wire. The detection hole is covered with a lid (15) of heat-resistant material during execution of the electrofusion process. The state of flowing of molten resin into the detection hole during execution of the electrofusion process is inspected through the lid and whether the fusion has been done successfully is confirmed by removing the lid after solidification of the resin. 
     Also disclosed is an electrofusion joint comprising a detection hole formed in the outer peripheral surface of said joint to reach a region near said electrical resistance heating wire, a transparent or translucent heat-resistant lid embedded in or fixed to said joint so as to close said detection hole. 
     Further disclosed is an electrofusion joint having an annular groove formed in the outer peripheral surface of said joint to reach a region near said electrical resistance heating wire, so as to define a pin- or bar-like core, and a stopper member provided above said core and capable of limiting the lift of said core.

Abstract: A press fabric, for use on papermaking and similar machines, is of the open-ended variety, and has loops at each end enabling it to be closed into endless form during installation on the machine by means of a pin seam. The machine-direction (MD) yarns 1, from which the loops are formed during the flat or endless weaving of the fabric, are coated multifilaments. The coating 3, either permanent, semi-permanent, or soluble, gives the multifilament 2 a monofilament-like structure, enabling good loop formation and stability. The use of multifilament yarn provides a fabric having improved elasticity in the machine direction, and a greater degree of compressibility, following the removal of a soluble coating material, than can be obtained using monofilament yarn.

Abstract: A speech recognition system estimates a set of Poisson intensities for a spoken word, each intensity representing a respectively different word from a vocabulary of words. Each of the functions used to calculate these intensities has two variable parameter values. In a training mode, the system changes the values of the respective variable parameters to optimize the likelihood that the results predicted by the estimates correspond to the actual spoken words. These optimized parameter values are then used by the system, in an operational mode, to recognize spoken words.

Abstract: An A-phase pulse (S A ) and a B-phase pulse (S B ) are transmitted from a laser interferometic measuring machine to a unit conversion device (5). When the distance-to-be-­measured (ℓ) is increasing, a conversion coefficient (D R ) is added to or subtracted from an initial value in an arithmetic calculator (53) at the rising edge and the trailing edge of the pulses (S A , S B ). The conversion coefficient has a digital value of M-digits and represents a reference distance λ/N, where is the wavelength of a laser beam (LB₁, LB₂) employed in the laser measuring machine and M and N are positive integers. A predetermined unit distance in the metric system corresponds to a unit number in the (M+1)-th digit. A distance pulse signal (S L ) is generated in response to a carry signal and a borrow signal from the arithmetic calculator, and is used in expressing a change of the distance in the metric system.

Abstract: The iron comprises an electrically heated soleplate (3), the desired temperature of which is controlled by a thermostat (5) by the said thermostat periodically interrupting and restoring the power supply. The thermostat (5) can be set by means of an adjusting element (19). The iron is provided with a first and a second indicating element (23, 25), with in each case two indicating states (activated/non-activated). The indicating elements (23, 25) provide information on the actual temperature reached with respect to the desired temperature set. After turning the adjusting element (19), according to the invention the indicating state of the indicating elements (23, 25) is obtained from the turning direction of the adjusting element (19), from the operating state of the thermostat (5) before and after adjustment of the adjusting element (19) and from the old indicating state of the indicating elements (23, 25) before turning the adjusting element (19). As a result, an otherwise complex thermocouple, required in addition to the conventional thermostat (5), is not needed. <IMAGE>

IPC: G06F11/10

Abstract: A computer system in a fault-tolerant configuration employs multiple identical CPUs executing the same instruction stream, with multiple, identical memory modules in the address space of the CPUs storing duplicates of the same data. The system detects faults in the CPUs and memory modules, and places a faulty unit offline while continuing to operate using the good units. The faulty unit can be replaced and reintegrated into the system without shutdown. The computer system employs a power supply system including a battery backup so that upon AC power failure the system can execute an orderly shutdown, saving state to disk. A restart procedure restores the state existing at the time of power failure if the AC power has been restored by the time the shutdown is completed. The system employs a pseudo-filesystem to dynamically manage the hardware components. A directory which appears as a standard, hierarchical directory in this filesystem contains a file for each component; each file maps to either a hardware component or a software module. The pseudo-filesystem hierarchy is determined during system initialization and is automatically updated whenever the software or hardware configuration changes. The pseudo-filesystem, called /config filesystem herein, is implemented as a Unix filesystem in the Unix filesystem switch. The multiple CPUs are loosely synchronized, as by detecting events such as memory references and stalling any CPU ahead of others until all execute the function simultaneously; interrupts can be synchronized by ensuring that all CPUs implement the interrupt at the same point in their instruction stream. Memory references via the separate CPU-to-memory busses are voted at the three separate ports of each of the memory modules. I/O functions are implemented using two identical I/O busses, each of which is separately coupled to only one of the memory modules. A number of I/O processors are coupled to both I/O busses. I/O devices are accessed through a pair of identical (redundant) I/O processors, but only one is designated to actively control a given device; in case of failure of one I/O processor, however, an I/O device can be accessed by the other one without system shutdown.

Abstract: A semiconductor body (1) is provided by growing epitaxial layers of semiconductor material on a substrate placed within a processing chamber and forming a mesa structure (3) on an upper epitaxial layer (2). The mesa structure (3) is formed by epitaxially growing, with the semiconductor body (1) still within the processing chamber, a first layer (4) of a semiconductor material different from that of the upper layer (2) on the upper layer (2) and then opening a window (5) in the first layer (4) to expose an area (2a) of the upper layer (2). A further layer (6) of a semiconductor material different from that of the first layer (4) is then epitaxially grown on the first layer (4) and on the said area (2a) of the upper layer. The first layer (4) is then selectively etched so as to remove the first layer (4) and the part of the further layer (6) carried by the first layer (14) leaving the remainder (60a, 60b) of the further layer (6) in the window (5) to form the mesa structure (3).
