Title: Manufacture of welded tube for column
Inventor: HORIE MASAYUKI
IPC: B21C37/08
Filed: 1995-05-16
Abstract: PURPOSE: To remove the projecting part of the weld bead without discharging chips or cutting chips by rolling down the bead when the bead temperature after the welding is in the prescribed temperature range. CONSTITUTION: The bead is rolled down when the bead temperature after the welding is in the temperature range of 400-750 deg.C. The projecting part of the weld bead formed on the outer surface is rolled down to be smooth and flat, and no chips or cutting chips are discharged. The projecting part is rolled down when the bead temperature after the welding is >=400 deg.C, and the rolling- down force is not so large, the bead of high temperature and small deformation resistance are concentratedly rolled down, and this work can be achieved by a compact rolling-down equipment. For example, when the bead temperature is <=350 deg.C, the deformation resistance of a steel tube is remarkably increased, and the bead height can not be set within the allowable range.  When the bead temperature is >=800 deg.C, a recessed part is generated due to the defective welds or the shrinkage during the cooling. When the bead is rolled down in the range of 400-750 deg.C, the bead height can be set within the allowable range, and the welded steel tube for a column free from any defective welds can be manufactured.

IPC: G06Q30/02
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain a method for strengthening the performance predictive function of a physical distribution resource plan(DRP) by estimating at least either of predictive future goods in stock or a supply required amount by using DRP logic. SOLUTION: In a distribution network 10 that consists of three retail stores that receive supply from one wholesale store, the retail stores obtain supply goods from the wholesale store and the wholesale store obtains them from a supply dealer respectively. Now, let us suppose that supply read time of products in each retail store is a prescribed week and that of the wholesale store is the prescribed week respectively. A prescribed period in future is estimated by using a DRP. A DRP table that reflects next week job actions over a prescribed period is created about each retail store and the wholesale store. The row of the DRP table of the wholesale store which corresponds to expected next week demand in the wholesale store is produced by totaling corresponding recommended order quantities of the three retail store DRP tables.  When the next week demand is specified, the DRP table of the wholesale store is completed. The quantities in the table are predictive values about goods in stock and supply required amount in the future.

Title: Power amplifier
Inventor: TOYODA YUKIHIRO
IPC: H03F3/26
Filed: 1992-05-11
Abstract: PURPOSE:To maximize a power addition efficiency before a saturation output point by generating a simulated square wave from an input signal, giving a fundamental and a 2nd harmonic component to a FET at a maximum level, amplifying power at a minimum operating angle and extracting only the fundamental wave component. CONSTITUTION:A single power amplifier uses a harmonic wave generating section 1 to generate various harmonic waves from an input signal of a fundamental component f0 and to give them to an amplitude phase adjustment section 2. The adjustment section 2 extracts only a 2nd harmonic component 2f0 in the harmonic waves together with the component f0 and adjusts the amplitude and the phase with respect to the component f0 and generates and outputs a simulated square wave by synthesizing the the adjusted component with the component f0. An input matching section 3 receives it and gives the component f0 and the component 2f0 to a FET amplifier section 4 at a maximum level. The amplifier section 4 amplifies the power by decreasing the operating angle of the simulated square wave with respect to an output signal of the matching section 3, and only the component f0 is extracted and outputted from the output signal by the output matching section 5. As a result, the power addition efficiency is maximized in the power amplifier before a saturation output point.

IPC: G01R13/32
Filed: 1992-03-25
Abstract: PURPOSE:To operate scanning lines one by one and modulate the luminance for every scanning line and to prevent errors resulting from the disconnection of scanning lines by inserting a projecting waveform shorter than the flyback time at a rise part or a fall part of a staircase and doing a switching operation during the projecting part. CONSTITUTION:A waveform 230 input from an input terminal 186 is converted to a waveform 231 by a resistance 187 and a diode 188. Every time the waveform 231 is input, the potential is accumulated by tone cooperative operation of a FET 189, the diode 188 and a capacitor 202. The potential is supplied to an OP-AMP 203 the lack of the high frequency band of which is corrected, and amplified at an OP-AMP 197. As a result, a staircase which rises at high speeds and can maintain the potential for a long time is formed. The staircase is combined with the waveform 231, thereby to obtain a staircase 236 having a projecting part inserted. A Schmitt level is set to the waveform 236. An inverter 220 is activated after the switching time is limited to the rise part of a waveform 241. Accordingly, the scanning lines are switched one by one, whereby the disconnection of the scanning lines halfway is avoided.
