Title: Method for continuously casting steel
Inventor: KANAZAWA TAKASHI
IPC: B22D11/16
Filed: 1990-01-11
Abstract: PURPOSE:To reduce friction between a mold and a cast billet and to slowly cool the cast billet by applying high frequency oscillation specified in amplitude and frequency in thickness direction of the cast billet. CONSTITUTION:In the continuous casting mold 1 for steel, the high frequency oscillation having 10 - 500mu amplitude and 1,000 - 10,000 cpm frequency is applied in the thickness direction of cast billet 6 with an oscillating generator 2. By this method, the friction between the cast billet 6 and the mold 1 is reduced and slow cooling to the cast billet is executed. In this result, the development of breakout caused by sticking and longitudinal crack in the cast billet 6 are prevented. The oscillating generator 2 uses eccentric type motor, etc.

Title: Method for separately using channels for mobile communication
Inventor: TAKANASHI HITOSHI
IPC: H04W72/04
Filed: 1995-01-17
Abstract: PURPOSE: To separately use channels by all base stations even when many base stations are present in a small area. CONSTITUTION: The interference wave level of an outgoing slot in which the base station is to transmit control signals at the time of channel retrieval is measured, and when it is not lower than a stipulated interference wave level, the interference wave level is measured in the other slots until the slot is found in a step 33. Also, the interference wave level of plural incoming slots from a mobile station to the base station to the outgoing slot is measured, and when it does not satisfy a stipulated value, repetition is performed from the retrieval of a different outgoing control channel in the step S37.  When the interference wave level is not satisfied in all the outgoing and incoming channels, the combination of the (m) (m>n) pieces of the incoming slots and the outgoing slots lower than the stipulated interference wave level is selected by the specified (m) pieces of the incoming slots and whether or not the interference wave level satisfies the stipulated value is verified again in the step S46 after the elapse of the fixed time.

Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To improve connection strength by making the shape of the butting portion of a beam to be butted against a column correspond with the shape of a column including curved column corners. SOLUTION: A column 2 is prismatic and the corners 21 of the column are curved. The connector 1 is used for connecting the column 2 and a floor beam 3, and the column 2 and a ceiling beam 3 and is formed of section steel with a U cross section, the shape of the butting portion 11 of the connecting hardware that is butted against the column 2 corresponds with the shape of the column 2 including the corners 21. The butting portion 11 is butted against a prescribed height of the column 2 (upper end or lower end) and welded, and beams 3, 4 are inserted into the connector 1 and welded and connected thereto. As the butting portion 11 has a shape corresponding with the shape of the column 2 including the corners 21, connecting the butting portion 11 by welding makes weld length increase and helps secure high connection strength.

Title: Descaling method for hot rolled steel plate
Inventor: ODOHIRA TOSHIHIKO
IPC: C25F1/12
Filed: 1981-01-16
Abstract: PURPOSE: To reduce the scale stuck on the surfaces of a hot-rolled strip of high temp. and to recover the heat contained therein by passing said strip in a fused salt tank provided with steam generating pipes, and conducting DC to the strip as cathode.  
     CONSTITUTION: A hot-rolled steel plate 2' of high temp. is passed into a tank 6' which has a large number of steam generating pipes 3' and contains the melt of NaOH as fused salt 4'. The fused salt is heated and low temp. steam is generated in the pipes 3' to recover the heat retained by the plate 2'. In this case, with the steel plate as cathode and the tank 6' or a separately provided electrode 5' as anode, fused salt electrolysis is accomplished, whereby the Fe 3 O 4  which is scale is reduced by the formed Na to Fe, and the scale is removed. Next, the steel plate is passed through the inside of a rinsing tank 7' whereby the fused salt stuck thereon is washed away and the production of the steel plate having no scale layers is made possible.

IPC: B01D63/08
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent the breaking of a melt sticking part or to easily repair a membrane cartridge formed by melt-sticking and fixing an organic filter membrane on the surface of a filter plate. SOLUTION: The producing method is by melt-sticking and fixing the organic filter membrane 9 arranged on the surface of the filter plate 8 having rigidity on the peripheral part of the membrane and applying a soft adhesive 13 for reinforcing in belt-state to cover the peripheral part of the membrane along the melt-sticking part 12. As a result, the membrane peripheral part is reinforced over the whose periphery because the soft additive 13 dissolves the filter membrane 9 to be integrated with the filter membrane 9 and to be stuck to the filter plate 8.  At the time of refreshing the used flat membrane cartridge 3, the soft additive 13 for reinforcing is dissolved and removed by dipping the membrane cartridge 8 in a sodium hypochlorite solution and the soft additive for reinforcing 13 is belt-likely applied to cover the membrane peripheral part along the melt-sticking part of the membrane cartridge 3.

Abstract: PURPOSE:To prevent dust from flowing in a vacuum chamber in the initial stage of the vacuum evacuation of the vacuum chamber by providing a vacuum suction groove between a plurality of the seal materials surrounding the circumference of the opening of the vacuum chamber and individually providing the first valve controlling the evacuation of the vacuum chamber and the second valve controlling the evacuation of the vacuum suction groove. CONSTITUTION:A vacuum suction groove 2a is provided between a plurality of the seal materials 3a, 3b surrounding the circumference of the opening of a vacuum chamber 1. The first valve 5 controlling the evacuation of the vacuum chamber 1 and the second valve 6 controlling the evacuation of the vacuum suction groove 2a are individually arranged and can be operated independently. That is, when the valve 6 is opened in the initial stage of the vacuum evacuation of the vacuum chamber 1 to discharge the air in the groove 2a, the groove 2a is reduced in pressure to press an opening and closing door 4 to the seal materials and the vacuum chamber 1 is sealed. Since the vacuum chamber 1 is immediately evacuated through the groove 2a even when there is a leak at this time, no dust flows in the vacuum chamber 1 even if a gap is generated and the dust is sucked. Subsequently, the valve 5 is opened to evacuate the vacuum chamber 1.
