Title: Buffer memory controller
Inventor: SHIYU YASUHIRO
IPC: G06F5/10
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To separate and extract each sample from a bit stream for a buffer memory which divides each sample of an input bit stream for every specific bit and successively stores these divided samples in word unit by dividing the input bit stream in every specific bit and storing these bit streams in a bit word memory. SOLUTION: A start word address generation part 312 reads the data including the 9th bit through the 3rd bit out of 10 bits and outputs the data after decimalization. A bit address generation part 314 reads the data including the 2nd bit through the 0-th bit and outputs them. Then the number of bits of each sample are accumulated at a sample pointer to separate the samples stored in a buffer memory part 315 from each other. Thus, the position of the 1st bit of the sample included in a word as well as an address stored in the part 315 are detected from those accumulated bits.

Title: Yarn filament conveying feed roll
Inventor: ABE YOICHI
IPC: B65H59/22
Filed: 1988-12-29
Abstract: PURPOSE:To dispense with a dancer roll or a louver or the like and make the promotion of automation and continuation for yarn filament conveyance as well as to make improvements in productivity in a labor-saving manner by connecting a roll divided at each yarn filament slidably to a drive shaft. CONSTITUTION:A yarn filament 1 is conveyed at a constant conveying speed V1 by a feed roll 2. In order to keep yarn tension T constant at a processor 3, there is necessary to give tension to a extensional or curly yarn filament piece by piece. Accordingly, a conveying speed V2 is given to it with a feed roll 12 with rolls divided at each yarn filament. In brief, V2 is set slightly speedier than V1, whereby a slip is produced by a friction plate 8, at each yarn filament, of the driven-driving feed roll 12, thus the yarn tension set by this friction plate is securable. According to this method, a dancer roll and a louver are no longer required and, what is more, the cost of equipment is curtailed and there is not damage to the yarn filament, leading to improvement in quality.

Title: Deflection yoke
Inventor: IN JINJIYUU
IPC: H04N9/29
Filed: 1993-12-28
Abstract: PURPOSE: To improve the productive efficiency of a deflection yoke by applying an induced current upon a leakage magnetic field preventing coil constituted adjacently to a horizontal deflection coil from an induction coil to automate the production process of the yoke. CONSTITUTION: A deflection yoke is mounted on the neck section of a cathode-ray tube and saw tooth pulses having prescribed frequencies are applied upon horizontal and vertical deflection coils. As a result, horizontal and vertical deflection magnetic fields are generated and deflected R-, G-, and B-electron beams are emitted from an electron beam, resulting in the formation of a deflected picture. When the pulses are applied upon the deflection coils, a leakage magnetic filed MI is formed over the side face of the cathode-ray tube in the forward-backward direction from the horizontal axis of the tube and prescribed amounts of induced voltage and current are periodically generated in an induction coil 12. Then a magnetic field generated from a leakage magnetic field preventing coil in the direction opposite to the magnetic field MI offsets the magnetic field MI.  Therefore, a coil 8 can be wound automatically by effectively conceling the magnetic field MI without receiving any influence from the intrinsic characteristic, such as the sensitivity, etc., of the deflection yoke.

Therefore, the CVD-SiC coating layer 12a in naturally separated form the bulk material 11. Each of the obtd. two CVD-SiC coating layers 12 is subjected to a surface finishing process to obtain a bulk material 15.

Title: Manufacture of permanent magnet
Inventor: KOBAYASHI OSAMU
IPC: H01F1/057
Filed: 1987-12-28
Abstract: PURPOSE:To improve a remanent magnetic flux density remarkably and to enhance a coercive force by a method wherein an alloy, whose basic components are at least rare-earth elements (including Y), a transition metal and boron, is melted and cast and then hot-worked at a strain rate in a specific range. CONSTITUTION:An alloy of a desired composition whose basic components are rare-earth elements (including Y), a transition metal and boron is melted in an induction furnace and is cast in a mold. Then, in order to give anisotropy to a magnet, the alloy is hot-worked between 500 and 1100 deg.C; its strain rate is increased; its remanent magnetic flux density Br and its coercive force iHc are increased; its maximum energy product (BH)max is also increased. Among others, a plastic working temperature of 800-1050 deg.C is good. When the strain rate of a hot-working process is fast, a crystal particle is made fine; on the other hand, orientation of the crystal particle becomes insufficient and a crack is produced. Accordingly, in order to eliminate the crack at an orientation rate of 80% or more, the strain rate of 10<2>/sec or less is desirable. If the strain rate is small, productivity is lowered remarkably, the crystal particle is grown intensely; a coercive force is lowered; therefore, the strain rate of 10<-4>/sec or more is desirable.

Under this structural design, the ink film cassette is protected against an external force, e.g. an unexpected trouble such as the accidental touching of the ink film cassette by hand. Thus the adequate protection of a printing mechanism is ensured.
