Title: Fuel replacing system
Inventor: KONNO TAKAHIRO
IPC: G21C19/18
Filed: 1988-04-18
Abstract: PURPOSE:To enable the parallel execution of a refueling operation and CRD exchange operation and to shorten the period for a periodic inspection by constituting the system in such a manner that taking-out coordinate positions or the coordinate positions of charged fuel in a reactor core can be displayed by a monitor device in a central control room. CONSTITUTION:A fuel gripper 14 descends and the fuel 12 is taken out by a fuel grapple 15 when an operator operates an on-board operation panel 16 at the time of executing the fuel replacement. The fuel grapple 15 forms the signal to announce the taking-out of the fuel when the grapple grabs the fuel. A computer 20 forms the in-pole coordinate signal of the taken-out fuel upon receipt of the fuel taking-out detection signal and transfers the signal to a core monitor device 22 of a central control room 21, to display the position of the taken-out fuel. The operation is carried out similarly even in case of charging the taken-out fuel. Then, the fuel taking-out and charging state at the time of the periodic inspection can be administered in the central control room and, therefore, the parallel execution of the fuel replacing operation and the CRD exchange operation which are the critical stage in a nuclear power plant is enabled.

Title: Radio communication device
Inventor: SHIMIZU YUUKIYU
IPC: H04B1/3822
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce a time required for updating position registration information. SOLUTION: A plurality of sectors 3 are formed in a flash memory 2. Two sectors or over among the sectors 3 are assigned for storing position registration information. The flash memory 2 is managed in a way that position registration information is stored in any of the assigned sectors and the other one sector or over acts like an idle sector to which no information is stored. When receiving update purpose position registration information, the flash memory 2 stores the update purpose position registration information to at least one idle sector, and the storage information of the sector having stored the position registration information before the update is deleted after storage of the update purpose position registration information is finished.  Since it is not required to delete the sector information that takes much time until the storage of the update purpose position registration information is finished to the flash memory 2 after starting the update, the time required for updating the position registration information can be reduced.

Title: Manufacture of semiconductor device
Inventor: NAKANO ATSUSHI
IPC: H01L29/78
Filed: 1993-03-30
Abstract: PURPOSE:To enhance a close adhesion of a polycrystalline silicon for use in particularly a gate electrode to a metal silicide film and to restrict a generation of separating or swelling. CONSTITUTION:After a gate insulation film 2 grows on a semiconductor substrate 1, a polycrystalline silicon film 3 grows and impurities are introduced for a low resistance. Thereafter, the surface of the polycrystalline silicon film 3 is etched by a reverse sputter method to form an amorphous silicon film 4. Thereafter, a metal silicide film 5 continuously grows by a sputter method. Thus, as the polycrystalline film 3 is not directly connected to the metal silicide film 5, it is possible to restrict a deterioration in a close adhesion of the polycrystalline silicon film 3 to the metal silicide film 5 even by thermal treatment for crystallization.

Title: Shield machine
Inventor: IKEDA MASANORI
IPC: E21D9/08
Filed: 1995-04-20
Abstract: PURPOSE: To simplify an operating mechanism by placing a copy cutter which is projected toward the outer peripheral surface of a cutter head by the operation of a single-acting cylinder and is retreated by the spring force of a compression coil. CONSTITUTION: High-pressure oil is supplied to the bottom side of a single-acting hydraulic cylinder 20 via hydraulic piping 21, and thereby a piston 20a is expanded to advance a support shaft 13 to cause a copy cutter 16 to project outwards from the outer peripheral surface 4a of a cutter head 4. As the cutter head 4 rotates, the natural ground around the cutter head 4 is drilled. To retreat the copy cutter 16 after the drilling is complete, the hydraulic tubing 21 of the single-acting hydraulic cylinder 20 is switched to the low pressure side and then the copy cutter 16 is retreated to an initial position along with the support shaft 13 by the spring force of a compression coil spring 15.  The spring force of the compression coil spring 15 in this case is sufficient to retreat the copy cutter 16 to the initial position by overwhelming the weight of the spring and frictional forces even if the copy cutter device 10 is located beneath the cutter head 4.

Abstract: PURPOSE:To execute an efficient high-speed retrieval by making a tree structure with two layer to manage broad information in a first layer and to manage detailed information with a necessary and minimum description in a second layer. CONSTITUTION:The tree structure with two layers to manage the broad information in the first layer and to manage the detailed information based on the necessary and minimum description in the second layer is made. In the tree structure of the second layer, only four-piece areas made into objects are expressed as the tree structure, simultaneously, the node of a digit 1 is deleted, it is integrated to the slave node, and thereby, the number of nodes can be reduced. When leaf parts are integrated by extension codes and the tree structure of the second layer is composed of only one leaf, by describing two kinds of area information with two kinds of leaves of the first layer through the use of division information, the number of leaves can be reduced. Thus, the data compression and efficient retrieval of multi kind area information can be executed.

IPC: B01J8/18
Filed: 1982-06-07
Abstract: PURPOSE:To prepare high purity silicon, in high efficiency, preventing the deposition of silicon to the inner wall of the reaction tube of a fluidized bed apparatus, by ionizing and charging high purity silicon particles, and contacting with a silicon- containing gas to precipitate silicon. CONSTITUTION:A gaseous mixture of trichlorosilane and hydrogen at a molar ratio of 1:1 is introduced through the feed line 4 to the reaction tube 1. Silicon seed particles 8 are introduced through the line 3 into the ionization chamber 5, electrically charged by the exposure to arc discharge generated by the DC source 6, and introduced into the reaction tube 1. The reaction tube 1 is heated at about 1,000 deg.C by the electrical furnace 7, and the silicon seed particle 8 is grown during the descending motion in the tube 1. Since the temperature of the reaction tube is relatively low, the deposition of silicon to the inner wall 2 of the reaction tube can be suppressed, and since the seed particle is activated by arc discharge, a sufficiently high rate of reaction and uniform silicon particles can be obtained.

Abstract: PURPOSE:To obtain a KANA (Japanese syllabary)/KANJI (Chinese character) converter which can reduce remarkably the file capacity by using a KANA key part (KANA characters) within a KANJI dictionary file as the variable length data. CONSTITUTION:Data DO-Dn are stored in a data file F2, and the data length of a key (KANA characters) part (A1, A2-) is variable. As shown in the figure, the key part A1 of data D1 (KO-U-SU) has three characters and the key part A2 of data D2 (KO-U-SU-iota) has four characters, respectively. Thus no waste is produced in a data area although a waste idle area is produced with the fixed data length. A Japanese word processing program 4 designates KANA characters (KO-U-SU) to undergo KANA/KANJI conversion and at the same time delivers a read instruction R. A data control program 5 loads a master index file M and a subindex file S to a region 8 of a memory 3 through a disk control program 6 and has a search based on the designated characters (KO-U-SU-I).
