Title: Dust collecting method for sintered ore
Inventor: KUMAHARA IKUO
IPC: C22B1/26
Filed: 1993-11-29
Abstract: PURPOSE:To effectively and cheaply collect dust to be generated in crushing of sintered ore by injecting compressed air toward the crushed sintered ore from a compressed air injecting nozzle provided under a primary crusher and collecting dust generated by crushing after forcibly floating it. CONSTITUTION:When sintered ore sintered by a sintering machine 21 is crushed by a primary crusher 3 in an exhaust ore part 2, compressed air is injected toward the sintered ore from a compressed air injecting nozzle 4 provided under the primary crusher 3. Dust 5 generated according to crushing of the sintered ore, and to be settled by gravity exists in the space to which compressed air is injected, and it is blown up by compressed air. The dust 5 forcibly floated is collected by a dust collecting machine 6 provided above the exhaust ore part 2. Since the dust to be settled to the lower part is also collected, dust collecting efficiency in the exhaust ore part 2 is improved.

Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To improve the operating efficiency of a network by learning and registering a source address with respect to an ATM address inquiry from a terminal equipment so as to reduce the probability of address analysis through a broadcast. SOLUTION: When an ATM address of an opposite terminal equipment 12 is not clear, an outgoing terminal equipment 11 inquires about it of a server 21.

When the ATM address is in existence, it is informed to the outgoing terminal equipment 11, and when not, the inquiry is broadcast to all terminal equipments via an ATM exchange 31. Upon the reception of the inquiry transferred from a server 21, the opposite terminal equipment 12 informs an ATM address of its own terminal equipment to the server 21 when the address is coincident with a protocol address of its own terminal equipment.  Then the server 21 informs it to the outgoing terminal equipment 11.

Title: Cutting off device for covering of shielded wire
Inventor: IJIRI TOMOYA
IPC: H02G1/12
Filed: 1990-11-02
Abstract: PURPOSE:To beautifully cut off the sheath of a shielding wire by making a cutter provided with a cutter holder which is centrifugally moved by the rotation of a rotor to act on the entire periphery of the shielded wire set at the center of the rotor. CONSTITUTION:When a start button attached to a front frame is pressed, a motor is started and a rotor 3 starts to rotate. As the rotor 3 rotates, an centrifugal force acts on a cutter holder 12 which rotates together with the rotor 3 in an integral state and the holder 12 moves to a central projecting section 12c by compressing a spring 13. As a result, a cutter 19 approaches the center of the rotor 3 and gets into a shielded wire 14 at the rotating center of the rotor 3 while the cutter 19 rotates together with the rotor 3. Thus the cutter 19 cuts into the section A of the wire 14 around the entire periphery. The moving limit of the cutter holder 12 is adjusted by means of an adjusting bolt 23 so that the cutter 19 does not cut the inner insulating covering 14c of the wire 14, but the outer sheath 14b only.

Abstract: PROBLEM TO BE SOLVED: To reduce the required time significantly by generating an original M-sequence and a sampled M-sequence and, when they are identical to each other, subjecting the sampled M-sequence to co-prime sampling thereby generating a pair of characteristic M-sequence having a conjugate complex frequency spectrums. SOLUTION: An M-sequence generator 21 generates an M-sequence which is fed to an M-sequence processor 23 in order to determine a characteristic M-sequence. It is then subjected to co-prime sampling through co-prime samplers 24, 25 to produce a pair of M-sequence having a conjugate complex frequency spectrums. The pair of M-sequence is outputted through a switcher 29 to a system 28 under investigation. Output from the system 28 is fed to a correlator 30 and a corresponding output co-prime-sampled M-sequence is taken out and subjected to Fast Fourier Transform at an FFT processor 31 to generate amplitude and phase response data of the system 28. This arrangement reduces the time required for measuring the frequency characteristics of system significantly.
