Title: Sticking method of steel belt and device therefor
Inventor: IWASAKI KENJI
IPC: B29D30/30
Filed: 1987-08-27
Abstract: PURPOSE:To enable the sticking operation of a steel belt to be achieved precisely by correcting its curved end side when it occurs by a method in which a sticking conveyer is separated from the contact bonding part of a forming drum, and while the central part and the side edge part of the rear end side of the steel belt are guided, the steel belt is brought in contact with the forming drum under pressure, whereby its inclined front end part and rear end part are butt-joined. CONSTITUTION:The sticking conveyer 2 driven synchronously with a forming drum 1 is arranged, and near the outer peripheral surface of the forming drum, the rockable splicer 9 composed of a splice roller 7 and a flange roller 8 is provided. When the front end part of the steel belt reaches near the contact-bonding part between the forming drum 1 and the sticking conveyer 2, the forming drum and the sticking conveyer are stopped, and the sticking conveyer is separated from the contact-bonding part of the forming drum. In this state, the splicer 9 is operated, and while the central part and the side edge part of the rear end side of the steel belt are guided, the steel belt is brought in contact with the forming drum under a prescribed pressure. The inclined front end part and the rear end part of the steel belt are contact-bonded by rotating and driving the forming drum in this state.

Title: Thyristor converter
Inventor: KIMURA YOSHIO
IPC: H02P7/292
Filed: 1990-08-10
Abstract: PURPOSE:To suppress voltage fluctuation at the input terminal of a thyristor converter, which performs regenerative operation or powering operation even with a weak AC power supply, by connecting the AC power supply with a resistor only during regenerative operation. CONSTITUTION:Basic wave IU1 of phase-U current when a thyristor 2 undergoes regenerative operation with control angle alpha=180 deg. and a load current IRU flowing through a resistor 6 connected with phase U are shown on the drawing. The load current IRU is in-phase with a phase voltage eUO. Current IUO flowing through a power supply impedance 5 can be represented by IUO=IU1+IRU, and the current IUO goes zero if the resistance R of the resistor 6 is selected so that the IU1 and IRU have identical absolute values. Consequently, voltage drop IUO.Z across the power supply impedance Z also goes to zero. As a result, input terminal voltage eU of the thyristor converter 2 can be represented by eU=eUO-IUO.Z=eUO and the input terminal voltage eU becomes equal to the power supply phase voltage eUO.

Abstract: PURPOSE:To attain reduction in the amounts of expensive components and to improve the nonmagnetism and hot workability, by reducing the amount of Ni as compared with SUS 316 steel and adding specified amounts of Cr, Mn, Cu, N, Ca and B without adding Mo. CONSTITUTION:The compsn. of an austenitic stainless steel is composed of, by weight, <=0.15% C, <=1.5% Si, 0.5-6.0% Mn, 17-23% Cr, 10-15% Ni, 0.1-3.0% Cu, 0.02-0.20% N, 0.001-0.020% in total of Ca and rare earth metals and/or 0.0005-0.015% B and the balance Fe.
