Abstract: A method and an apparatus are provided for inserting and removing a communication wire in and out of a pipeline by air flow, in which static electricity can be prevented from being generated, and a long communication wire can be inserted and removed. The communication wire is fed from a reel, and inserted into a pipeline through a blowing head. Compressed air is also sent from a compressor to the pipeline through the blowing head. A drop cylinder is attached to a T-branch on the way of the pipeline, conductive material stored therein is supplied into the pipeline at a controlled rate. A recovery bottle is attached to the outlet side of the pipeline so that the air flow blowing out of the outlet side is passed through a filter 11, and at the same time the conductive material is recovered. By making the conductive material pass through the pipeline together with the air flow, generated static electricity can be eliminated, and the communication wire can be prevented from contacting tightly with the pipeline because of the static electricity.

Abstract: A tuyere (10) for refining molten metals or melting metal scrap or oxides charged into a vessel. The tuyere (10) comprises three concentric pipes (12,32,40) of copper or stainless steel encased in refractory (44). An annular stream of natural gas surrounds an annular stream of oxygen which in turn surrounds a core stream of natural gas. All three streams are expanded as they flow through the tuyere (10) and as a result an accretion (50) forms at the tip of the tuyere. The accretion protects the tuyere (10) and the gas streams are controlled so that the accretion (50) is maintained at a desired size which neither blocks the tuyere (10), nor permits burnback of the pipes (12,32,40).

Abstract: There is described a method for recovering symbol synchronism useable in the demodulators MPSK or QAM. In accordance with the method in question there is used a VCO inserted in a PLL for sampling the symbols at the double-frequency of the symbol frequency and for generating the symbol reading clock. The algebraic sum with alternating sign of the absolute value of four consecutive samples constitutes a generic term of an error sequence which, appropriately filtered, controls the VCO. The central values of the symbols at the reading instants are obtained by interpolating the respective samples. A hangup of the PLL is revealed by the sign discordance between samples taken in pairs. In case of detection, the sequential order of the interpolated samples is changed and the symbol reading clock phase inverted. The sign of the error sequence controlling the VCO is also inverted in order to stabilise the equilibrium point of the PLL.

Abstract: A full adder circuit having a plurality of full adders each provided for each bit, each full adder comprising: a calculation block (31a) responsive to a first carry signal given by a preceding stage bit as a differential signal and two external input data (A1,B1) to be added at a present stage bit, for outputting addition data calculated on the basis of the first carry signal and the external input data as two differential signals, and further outputting a second carry signal to a succeeding bit as a differential signal indicative of whether a carry is generated by the present stage bit or not; and a latch type sense amplifier (16a) for outputting an addition result (SUM) of the present stage bit, after having differentially amplified and latched the addition data outputted by the calculation block. Since the addition operation is made on the basis of a minute potential difference (before amplification), it is possible to shorten the required charging time and to reduce the current consumption. In addition, since the sense amplifiers (16a) are provided with the latch function (18a), it is possible to control the differential amplification operation and the latch operation on the basis of a common sense amplifier activating signal (SAB), so that the number of elements can be reduced.

Abstract: In knitting a desired knit fabric (5), first of all, knitting needles of one of a pair of needle beds in a range corresponding with a knitting width of the desired knit fabric are fed with a draw yarn and a course of stitches is formed out of the draw yarn (4). Then, a part or all of the knitting needles used for knitting the draw yarn are fed with a knitting yarn and a course of stitches is formed out of the knitting yarn. Thereafter, the knitting needles of the front and the rear needle bed in the range corresponding with a knitting width of the desired knit fabric are fed with the knitting yarn and the initial portion of the desired fabric is knitted. Subsequently the knitting needles of either front or rear needle bed are fed with the knitting yarn and thereafter the knitting needles of another needle bed are fed with the knitting yarn and tubular plain stitches are knitted. Then knitting for obtaining the desired knit fabric is carried out. The draw yarn is drawn out of the knit fabric after the completion of the knitting. Next, a yarn end remaining at the initial portion is pulled out from the knit fabric, and the pulled-out yarn end is cut in a region near a side end of the knit fabric in a state that the initial portion is contracted. The cut end of the pulled-out yarn end is pulled back into the initial portion of the knit fabric by expanding the contracted initial portion in a direction wherein the contraction thereof is loosed.

Abstract: A portable radio communication apparatus has an upper casing and a lower casing which are rotatably connected to each other by a shaft. To use the apparatus, the user rotates the upper casing to an unfolded position thereof and then extends a retractable antenna. The upper casing is dimensioned sufficiently smaller than the lower casing, as measured in the lengthwise direction. The lower casing is so tapered as to orient a transmitter portion toward the user's mouth. Even when the upper casing is retracted to over the lower casing, minimum necessary keys on the lower casing remain exposed to the outside. In this configuration, even when the casing is folded, the transmitter portion and a receiver portion do not conceal each other and allow a conversation to be held thereon. Since minimum necessary keys are directly accessible even when the casing is folded, it is not necessary for the user to unfold the casing.
