Title: Memory control system
Inventor: TAKAHARA TORU
IPC: G06F12/02
Filed: 1991-09-11
Abstract: PURPOSE:To shorten the time required to specify a track and to obtain high throughput by writing or retrieving chain information or searching a free track at the time of data input by a control part without the intervention of a CPU. CONSTITUTION:The control part 17 searches for the free track in the document control area in a memory 16 and writes it in a next track address register(TAR) 3. An address counter 2 receives the chain information from the TAR 3 and outputs a next track address request signal to the control part 17. At the same time, data begin to be transferred from a data bus 100 to the memory 16. The control part 17 informs the host CPU 13 of the track number only when the track is the head track of a page. The control part 17 receives the next track address request signal and searches for a free track again. Once the free track is found, its track number is written in the TAR 3 and after free track information and control information are written in the control area, chain processing is performed.

Title: Time series investigating method and variable sequence generating method
Inventor: BENJIYAMIN MERAMEDO
IPC: G06F7/58
Filed: 1991-09-11
Abstract: PURPOSE:To use the traffic investigation of a communication system for a waiting matrix system to be modeled by converting the random number sequence to be the same distribution to a variable sequence, which is correlative, having the desired peripheral distribution. CONSTITUTION:An innovation change amount has desired probability distribution in a block selected for introducing desired self-correlation. The fractional part of the total sum is operated as the element of an adding operation to define '1' containing the new innovation change amount constituted as the first change amount of a desired output random number sequence as a normal. This process is recursively repeated so as to pull out the correlative change amount of the desired random number sequence having the uniform probability distribution. Further, in order to enlarge the value area of the usable self-correlation function, the correcting form of the process using the change amount of the produced random number sequence is utilized so that the odd-number change amount of the random number sequence can form the corrected random number sequence replaced with the change amount having 'those values at the one-dimensional random number sequence' although the even-number change amount keeps the original value.

Abstract: PURPOSE:To increase dimensional stability and bending strength by using metallic pipes having different outside diameters to form the front and rear parts of a ferrule to be coupled to a sleeve, etc. and molding concentrically and integrally both metallic pipes together with an optical fiber inserted therein by a resin. CONSTITUTION:The large-diameter metallic pipe 5 is supported by the mold face of a metallic mold 10 and the small-diameter metallic pipe 6 is supported by a metallic mold 11 in such a manner that one end thereof is positioned on the inside of the mold 11 and one end on the outside of the mold. The pipes 5, 6 are concentrially disposed in the partly superposed state. An optical fiber core 1 exposed partly with the optical fiber glass part 2 is inserted and held to the center thereof. The glass part 2 is drawn to the outside from a hole part 12 for insertion of the optical fiber and the remaining part of the core 1 is drawn to the outside from one end of the pipe 6. For example, an epoxy resin is injected through a resin gate 13 by which the optical ferrule held with the core 1 and the glass part 2 at the center and having the collar part 4 is integrally molded. The dimensional stability and bending strength as the ferrule are thus increased.

Filed: 1993-10-18
Abstract: PURPOSE:To simply obtain a resin filler excellent in adhesion to a resin and dispersibility without requiring different treatment according to kinds of a matrix resin by coating the surface of a resin filler with a specific thermoplastic elastomer. CONSTITUTION:An epoxy-modified block copolymer obtained by epoxidizing a double bond of an unsaturated carbon of a conjugated diene compound of a block copolymer consisting of (A) a polymer block composed mainly of a vinylaromatic compound and (B) a polymer block composed mainly of a conjugated diene compound is uniformly applied to the surface of a resin filler, preferably in an amount of <=10wt.% based on the filler. The adhesion treatment is generally preferably carried out using the modified block copolymer as its solution or an emulsifier.

Title: Laser beam machining device
Inventor: NAKADA YOSHINORI
IPC: B23K26/14
Filed: 1994-10-25
Abstract: PURPOSE: To obtain the current distribution of an assist-gas suitable for high speed cutting. CONSTITUTION: In a nozzle 42, a nozzle hole 42a for emitting the laser beam and an assist gas is installed. The internal face of this nozzle hole 42a is provided with a spiral like groove 42b. This groove 42b is made in a valley shape. That is, it is the groove of a shape of female screw. When a work is cut with a laser beam machining device, by using the nozzle 42, the flow rate of the discharged assist gas is made slower as coming nearer the internal face of the nozzle hole 42a. Accordingly, the assist gas is jetted at high speed at only near the focus of the laser beam. As a result, the high speed cutting can be realized.

Title: Molded magnet roller and manufacture thereof
Inventor: HIRATA MICHITOSHI
IPC: G03G15/09
Filed: 1988-10-14
Abstract: PURPOSE:To give magnetic anisotropy concentrated in one direction to each magnetic pole by constituting a molded body of magnet powder of a boss section covering a core shaft and plural projecting magnetic pole pieces radially projecting over a prescribed angle range from the boss section. CONSTITUTION:This molded magnet roller is constituted of a core shaft 1 of a magnetic substance and magnetic-powder molded body 2 molded together with the shaft 1 inserted into the body 2. The molded body 2 is provided with a plurality of projecting magnetic pole bodies 12 radially projecting from a thin boss section 11 covering the core shaft 1 over a prescribed angle range and each projecting piece is oriented and magnetized to magnetic anisotropy from the front end to the base end. Since the magnetic reluctance of this magnetic circuit is high at the boss section 11 due to the narrow passage and low at the shaft 1 due to the large diameter, most of the magnetic lines of force pass to the other side from the projecting pieces 12 through the shaft 1 and the orientation of the axis of easy magnetization of each projecting piece 12 shows such strong anisotropy that the axis is concentrated in one direction toward the base end from the front end of the projecting piece 12. Therefore, the magnetic lines of force are concentrated in one direction in each projecting piece 12 and magnetic fields are produced at the front ends of the projecting pieces only.

Title: Graphic pattern extracting system
Inventor: OSADA SHIGEMI
IPC: G06T1/00
Filed: 1985-11-20
Abstract: PURPOSE:To extract each type of symbol without increasing matching time as well as dictionary pattern capacity, by writing a common partial pattern to a part of a square pattern of an optional size within a graphic together with a discrimination character written into the common partial pattern and recognizing this pattern and said discrimination character for extraction of the square pattern. CONSTITUTION:A graphic pattern is stored in a picture memory 102 from a picture input device 101 under the control of an address control part 110. A reference point detecting circuit 104 detects a reference point and a corrected lattice point address is held by a lattice point table 105. The partial picture data is read out and the initial lattice point label codes are produced by both circuits 107 and 109. Then a circuit 112 executes the check processing to an area of a prescribed size centering on the lattice point containing said label code. Thus a lattice point label code deciding circuit 121 obtains the label codes of lattice points. The duplicate symbols are deleted by a circuit 123 together with corrections carried out by correction circuits 124, 126 and 127. Thus the lattice point label code is obtained for recognition of the graphic pattern. Based on this label code, both a common part and a discrimination character are recognized via a symbol dictionary 128. Then a square pattern in extracted.
