IPC: H01B13/02
Filed: 1995-03-15
Abstract: PURPOSE: To improve transmission characteristics, to improve mass production, and to reduce cost by continuously heat-welding two pair of polyethylene insulat ing coatings to each other. CONSTITUTION: One pair T is formed by twining two core wires (a), (b) formed by insulating and coating conductors 1 by polyethylene, a plurality of pairs T are formed, further twined, and coated with a sheath 3 from the outside. In this case, polyethylene insulating coatings 2 of the two core wires (a), (b) of respective paired T are continuously heat-welded to each other. That is, respective core wires (a), (b) are continuously heat-welded by hot air after respective core wires (a), (b) are twined. Accordingly, the twine of the paired T is not easily loosened, and the distance between the conductors 1 can be held constant. Therefore, transmission characteristics are improved, and the core wires can be reliably integrated by a simple method even if they are integrated pairs, and therefore, mass production can be improved, and the cost can be reduced.

Abstract: PROBLEM TO BE SOLVED: To decide document size in a short time with simple constitution. SOLUTION: The number X of white pixels while a cover is nearly is counted (104) and the number Y of white pixels while the cover is closed is counted (114). While the cover is closed, it is judged that the part of scanning lines other than a document consists of white pixels and while the cover is almost closed, it is decided that the part other than the document is not white pixels, so the difference between the number Y of white pixels and the number X of white pixels is calculated to obtain the number Z of pixels outside the document (116). Further, the difference between the number Z of the pixels outside the document and the total number (e.g. 4864) on the scanning lines is found to calculate the number A of document pixels corresponding to the part of the document on the scanning lines (118).  On the basis of the number A of document pixels and the detection signal from an optical sensor for longitudinal/ lateral decision making, the document size is decided (122).

Abstract: PURPOSE:To realize a high-speed transistor by forming an intrinsic base region of an npn transistor after a high temperature heat treatment process so that shallow base and emitter regions can be formed, whereby a side wall of the emitter region can be formed into a double structure. CONSTITUTION:Only a Si3N4 film 17 to be used as intrinsic base and emitter regions 20 of an npn transistor is removed after a thermal oxidation treatment, and an intrinsic base 8 having an electical continuity to a graft base region 7 is formed by introducing p-type impurities into the regions from which the film was removed. An SiO2 film 13 located above regions to be used as a collector 16 of the npn transistor and a base 26 of a pnp transistor, a p<+>-type polysilicon 6, and a Si3N4 film 27 are sequentially removed. An emitter region 9 and a collector region 6 of the npn transistor and a base extraction region 61 of the pnp transistor are formed by introducing impurities into the regions from which the films were removed. An isolation film between the base region and the emitter region is formed into a double structure made of a SiO2 film 13 and a Si3N4 film 27, and hence it is possible to reduce a leakage current and an emitter-base junction capacitance. Therefore, shallow base and emitter regions can be formed, and a high-speed transistor can be realized.

Abstract: The present invention relates to a multicarrier demodulator for separating and demodulating a digitalized frequency multiplexed signal into a plurality (L) of individual channel signals, with the separation being performed using a frequency division demultiplexer (FDM). The separated channel signals are each filtered using bandwidth limitation filters and thereafter demodulated using a synchronous demodulator. Following demodulation, the signals are filtered by interpolation filters, data (Nyquist) filters, and subsequently decided upon in a decider. The invention is characterized by the fact that the demodulator operates upon a pair of phase displaced complex channel signals.
