Abstract: A regional common-use block for a CATV system, which can be flexibly managed with increased convenience according to regional requirements, and which does not require a large-scale installation at each subscriber location, thereby lowering cost to each subscriber. Additionally, a CATV system using a plurality of the regional common-use blocks wherein a regional common-use block is interposed between a CATV center and each subscriber instrument and includes a set-top-converter (STC) which is commonly held by a specified unit number of subscribers in a local area, and wherein switching control is conducted to transmit an output of a STC to a plurality of subscribers. The common-use block separates multiplexed signals from the CATV center, converts the separated signals by each STC, controls circuit switching means, modulates the signals by RF modulating means and subsequently transmits the requested programs to subscribers.

Abstract: The present invention provides a X-ray beam position monitor, including a diamond plate placed so that the X-ray beam pass through diamond plate, and a plurality of electrode pairs placed on both sides of the diamond plate. The monitor makes it possible to monitor position of high power X-ray beam with high accuracy and at high speed. In addition, the monitor can be stably operated and reduce costs for manufacturing itself.

Abstract: The invention provides an insertion device for use with synchrotron radiation, including a horizontal undulator including a plurality of magnets linearly arranged along an axis of electron beams so that alternately positioned magnets have common polarity, and a vertical undulator including a plurality of magnets linearly arranged along an axis of electron beams so that alternately positioned magnets have common polarity. The horizontal and vertical undulators are perpendicularly centered about axes thereof, and arranged to be axially offset so that magnetic fields produced by the horizontal and vertical undulators are perpendicular to each other and a magnetic field produced by one of the horizontal and vertical undulators is inverted for each period of a magnetic field produced by the other. The insertion device is positioned in a straight section between bending magnets of a circular accelerator. In operation, the insertion device causes electrons beams to rotate alternately in opposite directions in a FIG.

Abstract: A blindstitch machine provided with a mechanism for feeding an end of the fabric to a position where a needle of the machine main body passes thereby to form the seam from the start end of the fabric, wherein the rotating amount of a belt is adjusted corresponding to the feeding amount of a feed dog of the machine main body, for instance, adjusted to synchronize the fabric feeding by the machine main body with that by the belt, so that the fabric is sewed without being wrinkled or stretched about the passing position of the needle.

Abstract: A nickel-based alloy which is excellent not only in anti-corrosion properties but also in workability is disclosed. The alloy contains 15 to 35 weight % of chromium; 6 to 24 weight % of molybdenum; wherein the sum of chromium plus molybdenum is no greater than 43 weight %; 1.1 to 8 weight % of tantalum; and balance nickel and unavoidable impurities. The alloy may optionally include no greater than 0.1 weight % of nitrogen; no greater than 0.3 weight % of magnesium, no greater than 3 weight % of manganese, no greater than 0.3 weight % of silicon, no greater than 0.1 weight % of carbon, no greater than 6 weight % of iron, no greater than 0.1 weight % of zirconium, no greater than 0.01 weight % of calcium, no greater than 1 weight % of niobium, no greater than 4 weight % of tungsten, no greater than 4 weight % of copper, no greater than 0.8 weight % of titanium, no greater than 0.8 weight % of aluminum, no greater than 5 weight % of cobalt, no greater than 0.

Abstract: To improve high-temperature strength, as well as increased resistance to wear due to sparking, a Ni-based alloy sparking plug electrode material for use in an internal combustion engine is provided. Such a Ni-based alloy sparking plug electrode material contain, by weight, from 3.1 to 4.3 of Al, from 0.5 to 1.5% of Si, from 0.45 to 0.65% of Mn, from 0.002 to 0.01% of C, from 0.005 to 0.05% of at least one of Mg and Ca, and, as necessitated, from to 2% of Cr, with the balance substantially Ni and inevitable impurities.

Abstract: An Ni base alloy for use in spark plug electrodes for internal combustion engines which consists essentially of, on a weight percent basis,0.1 to 1.5% Si,0.1 to 0.65% Mn,3.1 to 5% Al,0 to 2% Cr,0 to 0.5% of one or more elements selected from the group consisting of Y and rare earth elements,0 to 5% Co,0 to 0.5% of Hf and/or Re, andthe remainder Ni and incidental impurities.

Abstract: A seam forming device is provided for a blindstitching machine for starting a seam at the fabric end. This device has a fabric feeding apparatus positioned direct in front of a feed dog, so as to enable it to form seams which begin at the fabric end at which sewing is initiated. This eliminates the unseamed portion at the fabric end at which sewing is initiated, which has previously been inevitable when sewing with a conventional blindstitching machine. Thus, with the present invention, it is no longer necessary to manually finish the seam after blindstitching.

Abstract: A position adjusting device for a shoulder belt in a seat belt assembly comprises a belt anchor into which the shoulder belt is loosely passed, an anchor support block supporting the belt anchor, a guide rail slidably holding the anchor support block, and a straight screw shaft which is arranged along a longitudinal direction of the guide rail and is screwed into the anchor support member, so that the anchor support block may be moved along the guide rail by the rotation of the screw shaft; the anchor supporting block having two female screw members screwed around the screw shaft, and is biased by an elastic member toward or away from each other.

Abstract: A vehicle seat belt retractor with a tension-reducing mechanism comprises a main winding spring biasing a toothed wheel in the belt-winding direction and an auxiliary winding spring biasing the reel shaft relative to the wheel. The positions of a stopper pawl biased by an over-center spring are controlled by a clutch plate associated with the wheel such that the wheel is stopped by engagement by the pawl after the belt is pulled out and done up, the slack is allowed to be taken up, and the user pulls the belt out slightly, thereby establishing the reduced-tension state. The pawl is released from the wheel to restore the winding bias of the main spring by a releasing clutch ring if more than slightly less than one revolution of the reel is required to take up slack in the belt after the reduced-tension state is attained.
