Abstract: A steel cord comprises steel filaments twisted around each other in a first direction about at least one steel core filament having a wave form. The twisted filaments are individually subjected to a rotation about their own axes. This steel cord is formed by deforming the core filament into a planar wave form and twisting the core filament in a second direction to a predetermined degree. The core filaments together with the other filaments are twisted in the first direction so that the twisted filaments are individually subjected to a rotation around their own axes in the first direction.

Abstract: The invention concerns a novel concept of "rail-less" propulsion of hoisting equipment, namely to provide two parallel rows of discrete, spaced, glidingly supporting points on which the end-beams of a crane or the like are adapted to slide, rather than by wheels on a pair of continuous rails. The gliding supports are placed on top of series of equi-distantly spaced columns and the end-beams length is at leasttwice the distance between adjacent supports. Various kinds of driving systems are described.

Abstract: A multicoordinate sensing head is disclosed which incorporates a particularly simple mechanical structure to mount the sensing pin in a casing such that the pin is movable in a plurality of directions. Each deflection of the free end of the sensing pin is converted by appropriately shaped components on the sensing pin and the casing into an axial movement of a radially constrained upper end of the sensing pin. The slight axial movements of the upper end of the sensing pin brought about by deflections of the free end of the sensing pin are registered by a photoelectric arrangement arranged in the region of the upper end of the sensing pin. This photoelectric arrangement generates a signal when the free end of the sensing pin is deflected.

Abstract: A switching network having a plurality of repeater nodes, wherein each repeater node checks the number of times data packet has been received. If in excess of predetermined number, the repeater node transmits a looped trunk detection packet, the looped trunk detection packet being arranged to be written with the node address of each of the plurality of repeater nodes within a looped trunk as its repeating history. The repeater node checks whether the node address thereof is written in the repeating history or not. If the result is negative, the looped trunk detection packet is repeated and transmitted by writing the node address of the repeater node in the repeating history. If the result is positive, the repeater node does not repeat transmission of the succeeding packets from the repeater node to the route of the looped trunk, and transmits a looped trunk notification packet to repeater nodes. The looped trunk detection notification packet then forbids to repeat transmission of the succeeding packets from each of the other repeater nodes to the route of the looped trunk.

That is, the passage 10 is communicated to a peripheral sliding part 12 of the bearing 5 from a throttle part 9 and the passage 11 is communicated to an internal peripheral sliding part 13 from the part 12. While a groove 14 is formed circumferentially along the periphery of the bearing 5 in a small-end of the rod 4, and this groove 14 is connected to an oil filler port 15.

Abstract: PROBLEM TO BE SOLVED: To obtain a display device which has a wide visual angle characteristic and obviates the occurrence of a residual image phenomenon by providing the device with plural apertures within picture element regions apart a specified distance from the end sides of picture element electrodes. SOLUTION: The picture element electrode 24 has plural apertures 24a. These apertures 24a regulate sub-electrode regions 50a, 50b, 50c existing at angles. The sub-electrode regions are regulated by the polygonal shapes formed by the lines connecting the centers of the nearest apertures 24a to each other. The aperture at the left lower corner of the picture element electrode 50c is formed by lacking the external shape of the picture element electrode 24 within the picture element electrode 50c. The sub-electrode regions 50a and 50c are congruent square shapes and the sub-electrode region 50b is a rectangular shape. These rectangular shapes respectively possess the one side commonly with the sub-electrode regions 50a, 50c.  The distances (d) and d' from the end sides of the picture element electrodes to the apertures are about 5 μm, more preferably >=2 μm, further preferably about 2 to about 10 μm.

Abstract: Coded modulation schemes based on codes for QPSK modulation are directly incorporated into QAM based modulation systems, forming trellis coded QAM, to provide a practical coding structure that is both efficient in bandwidth and data reliability. Concatenated coding with QPSK based trellis coding and symbol error correcting coding is used. In an encoder (Fig. 2), an N-bit QAM constellation pattern (80) is divided into four subsets, each including N/4 symbol points of the constellation pattern. A two-bit QPSK codeword (92) is assigned to each of the four subsets (82, 84, 86, 88). A symbol to be transmitted is first encoded using an outer error correcting encoding algorithm, such as a Reed-Solomon code (12). Part of the symbol is then encoded (48) with an inner code that comprises a rate 1/2 trellis encoding algorithm to provide a QPSK codeword, which is mapped (50) with the remaining bits of the symbol to provide a modulation function, wherein the remaining bits (94) correlate the symbol with one of the symbol points included in the subset defined by the QPSK codeword. At a receiver (Fig. 3), the recovered modulation function is pruned (62) to provide a set of metrics (66) corresponding to the subsets and to provide a plurality of conditional determinations of the constellation point identified by the remaining bits. The metrics are used in a rate 1/2 trellis decoder (68) to recover a first bit that is encoded using a rate 1/2 encoding algorithm to recreate the QPSK codeword. One of a plurality of the conditional determinations is selected in response to the recreated codeword. The selected conditional determination is combined with the recovered first bit to provide a decoded output that is further decoded using a symbol error correcting algorithm such as a Reed-Solomon code (36). <IMAGE>
