Abstract: An improved wing-type ground anchor. The ground anchor includes a central body portion, wings radiating laterally from the body portion, and a leg portion at the front end of the body portion GROUND ANCHOR that operates like a star-point drill for penetrating the ground. The sides of the leg portion each include a plurality of sharpened leading side edges which are longitudinally offset from each other. Each of the wings also includes a plurality of sharpened leading side edges which are longitudinally offset with respect to each other. The offset leading side edges and wing edges progressively extend greater distances laterally outward from the body portion along the length of the leg portion and the wings. Since smaller side edges and wing edges are advanced first, the staged side and wing edges facilitate passage of the ground anchor through soil.
Abstract: A switching-oriented signaling load between a switching center (VMSCA) that receives a request for the connection setup and an access mobile switching center (GMSCA) that initiates optimized routing in inter-network fashion that is lower compared to the known method is achieved. The access mobile switching center (GMSCA) enters a destination address (AVMSC) offered by the home network (HPLMN) of a called radiotelephone subscriber (B-MS) or a destination address (AB′) offered by a visited mobile switching center (VMSCB) given call redirection into a message (ANM) that signals the creation of the call connection. It sends the message to the switching center (VMSCA) in order to be interpreted thereat for charging for the call connection. The assigning of a reference number by the originating switching center that implements the charging and the transmission of a separate MAP message (not call destination) by the access mobile switching center are thus no longer necessary.
Abstract: A catheter arrangement has an active catheter, positionable in a vessel or organ of an animal, having at least one transducer disposed proximal the catheter tip; and a fixed catheter, also positionable within the animal in the vicinity of the active catheter, carrying a number of reference transducers. A signal processing unit is arranged to selectively operate the transducers to send and receive signals between the active and fixed catheters. The signal processing unit operates to calculate from the received signals at least two independent locations of the active catheter relative to the fixed catheter and to combine the independently calculated locations to provide a weighted average determination of the location in which the relative contributions of the calculated locations to the determined location decrease as their associated error values increase.

Abstract: Method of checking for the presence of connection balls of components, in particular of ball grid arrays by projecting light obliquely onto the components to create reflections and shadows at the connection balls and any impurities, detecting the reflections and shadows and evaluating the detected shadows and reflections to determine which are from connection balls and which are from impurities.
Abstract: By fusing reinforcing tapes with bottom end attaching portions of fastener tapes by pressurizing heating means with different pressures (i.e., high and low), thus weakening of attaching portions can be prevented. Core threads are fitted to side edges of fastener tapes to form core portions. Reinforcing tapes formed of thermoplastic elastomer film or thermoplastic resin film are fused to wrap tape end portions including the core portions so as to form the bottom end attaching portions. The reinforcing tapes fused the core portions and vicinity portions to the fastener tapes with a low pressure and at tape main body portions to the fastener tapes with a high pressure, thereby making the core portions and the vicinity portions flexible and thick and making the tape main body portions stiff and thin to form stepped portions. The stepped portions are positioned outside flanges of a slider.
Abstract: A printer or copier has a developer station with a toner dispenser in which the toner is fed from a toner box to a transverse transport above a dosing apparatus. The transverse transport includes a helix driven by a drive mechanism. The helix has a pitch H that varies along its length or a thickness D that varies along its length so that the speed of conveyance in the transverse direction decreases over the conveyance path. The rotational speed of the helix is variable by adjustment of the effective length of a drive arm or an extent of an eccentric.

Abstract: A process of forming a silicon thin film includes the steps of: irradiating a pulsed rectangular ultraviolet beam on an amorphous or polycrystalline silicon layer formed on a base body, to thereby form a silicon thin film composed of a group of silicon single crystal grains which are each approximately rectangular-shaped and which are arranged in a grid pattern on the base body. In this process, the moved amount of a ultraviolet beam irradiating position in a period from completion of an irradiation of the rectangular ultraviolet beam to starting of the next irradiation of the rectangular ultraviolet beam is specified at 40 &mgr;m or less, and a ratio of the moved amount to a width of the rectangular ultraviolet beam measured in the movement direction thereof is in a range of 0.1 to 5%. Further, a selected orientation of the silicon single crystal grains to the surface of the base body is approximately the <100> direction.
Abstract: An apparatus for supplying air and at least one additional gas to a respirating subject has a container with an open end for receiving air, which is connected to a tubing system for conveying gas to the subject. The additional gas is supplied from an additional gas source via a metering system and a supply line to the container. As gas is supplied to the subject during inspiration phases by a compressor, air will flow into the container via the open end. At the same time a flow of additional gas is supplied to the container via a point of entry. During expiration phases gas will be diverted via a flow divider to flow back to the container via the supply line for the additional gas. A homogeneous and controllable concentration of additional gas is obtained within the container before each inspiration phase. The apparatus requires only a few components, making it a low cost apparatus, but it provides a good control of the concentration of additional gas supplied to the patient.
