Title: Text retrieving device and its method
Inventor: SHIBATA SHOGO
IPC: G06F17/30
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of retrieving processing by making it possible to reuse an initial operation result at the time of next appearance when an overlapped pattern exists in a retrieving character string. SOLUTION: A two-gram index storing part 101 uses two continuous characters in a retrieved text as a key and stores a two-gram index registering the positions of the characters concerned in a retrieved text. An overlapped pattern detection part 103 extracts an overlapped pattern constituted of characters more than two continuous characters from the retrieving character strings stored in a retrieving word storing part 102. A position retrieving part 104 retrieves the existing position of the overlapped pattern detected by the detection part 103 and stores the retrieved result in a comparing operation result storing part 105. The position retrieving part 104 retrieves the existing positions of characters other than the overlapped pattern and acquires the existing position of the retrieving character string based on the retrieved results and the contents stored in the storing part 105.

Filed: 1988-05-17
Abstract: PURPOSE:To increase the interval between a spring member and a frame member by a spherical projection and a support member and to attach and detach an original pressure plate smoothly by providing the spherical projection to the spring member. CONSTITUTION:When the original pressure plate 1 is inserted from above as shown by an arrow A so that the plate 1 is set on the frame member 4, the tips of support member 2 abut on the spherical projections of spring member 5 and when the original pressure plate 1 is further inserted, forces operate on the spherical projections of the spring members 4 in leaving directions from the frame member 4, so that the support members 2 are further inserted. At this time, the support members 2 receive reaction forces from the spring member 5 and are pressed against the frame member 4 and fixed tightly. When the original pressure plate is detached, it is detached smoothly by the same operation with the insertion. Consequently, the attachment and detachment are performed smoothly.

Title: Method for controlling distribution of blast furnace charge
Inventor: YAMAGUCHI KAZUYOSHI
IPC: C21B5/00
Filed: 1983-07-01
Abstract: PURPOSE:To control surely the distribution of blast furnace charge with high accuracy by measuring continuously the max. temp. on the surface of the charge at the top of the blast furnace with an IR television camera and controlling the operation by the control values of an influx rate and max. temp. CONSTITUTION:The max. temp. on the surface of the charge at the top of a blast furnace is continuously measured with an IR television camera provided in the mouth of the blast furnace. The case when the measured value in the late period is relatively lower than the measured value with all the measured values of each charge unit is regarded as an influx phenomenon and the influx ratio is defined as (influx ratio) = (the number of influx generated)/(the number of measurement to be changed over). Control values are adequately made respectively with such reflux ratio and max. temp. The operation is controlled in accordance with said control values, by which the distribution of the charge in the blast furnace is surely controlled with high accuracy in correct timing.

Title: Galvanomirror holding structure
Inventor: NAKAGISHI TOSHIO
IPC: G11B7/09
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To hold a galvanomirror at a prescribed rotary position by arranging plural magnets including N pole and S pole magnets around the rotational centers of movable and fixed parts, and making the movable side magnet face the fixed side magnet. SOLUTION: On the base of a mirror holder 100, a ring-shaped magnet 140 is provided so as to surround a downside bearing part 108. Besides, a stator is provided with a ring-shaped magnet 150 so as to surround a downside center pin 124. The N pole of the magnet 140 and the S pole of the magnet 150 face each other and this state the S pole of the magnet 140 and the N pole of the magnet 150 becomes a neutral state. When the mirror holder 100 is rotated from such a neutral state in clockwise direction, since the N pole sections (and S pole sections) of the magnets 140 and 150 partially face each other, repulsive force is generated. With this repulsive force, the mirror holder 100 receives energizing force so as to recover the neutral state. Thus, a galvanomirror 26 can be held at the neutral position all the time excepting for rotational driving.

IPC: B65G47/14
Filed: 1986-05-26
Abstract: PURPOSE:To aim at separation of parts from their entanglements as well as their orderly conveyance, by transferring parts on a spiral feed passage with rotational vibrations of a bowl, while once dropping them from the feed passage at the point midway in the feed passage, and transferring these parts in a way of intermittent suction with a magnet. CONSTITUTION:In an inner circumferential surface of a rotatively vibrating bowl 2, there is provided with a spiral feed passage 3 ranging from a bottom part to an upper takeout feed passage 8, and in the intermediate part, there is provided with a steep inclined part in succession to a dropping part. In an outer circumference of the bowl 2, there is provided with a drum which is rotated by a motor 6, while at the inside of a peripheral wall, a magnet 5 is attached to the whole inner circumference at an interval of more than double size double size of each part 9. Magnetic force should be set, insomuch that the part 9 will not drop off during transference. With rotational vibrations, the part 9 is made to go up spirally on the feed passage 3, and if it reaches an intermedaite part, it drops and separates from the passage, and the part is attracted by dint of the magnet force of the magnet 5, going up the steep inclined part, and again it reaches the spiral feed apssage 3, but at this time, such a part that is had in an attitude will not be attracted due to a difference in suction force so that it is put back to the inside of the bowl 2, thus the aligned part alone reaches a takeout position.

Title: Production of high purity zinc
Inventor: KANDA MINORU
IPC: C22B19/04
Filed: 1995-04-21
Abstract: PURPOSE: To easily produce high purity zinc by adding an element with the ratio of the vapor pressure to that of zinc specified at the zinc distillation temp. to zinc and distilling the mixture. CONSTITUTION: In the refining of metallic zinc by distillation, an element having a high affinity for the impurity metal in raw zinc and extremely difficult to vaporize as compared with metallic zinc is added, hence the vapor pressure of the impurity metal in the raw zinc is lowered to increase the vapor pressure difference from zinc, and the separability from zinc is enhanced. Accordingly, an element with the ratio of the vapor pressure to that of zinc controlled to <=10<-3> at the zinc distillation temp. is added, and distillation is conducted. The element in the amt. of >=10 times that of impurity is added by <=1% of the raw zinc. Gold, platinum and lead are used as the element to be added. Consequently, a useful material for producing the zinc selenide to be used in a blue light emitting diode, etc., is obtained.

Abstract: PURPOSE:To form a device in a small size and in light weight, by generating an electric discharge caused by high voltage from an ignition coil and an electric discharge, performed by directly applying residual voltage of a capacitor to an ignition plug, through a single circuit. CONSTITUTION:Before the ignition timing when a thyristor 11 is opened, a capacitor 5 is charged through an inverter 2, transformer 3, diode 4 and a primary coil 8a.
