Abstract: PURPOSE:To prevent temper-brittleness of a weld zone and to improve the toughness thereof by adding further a rare earth element to an Fe welding rod contg. a specific amt. of C, Si, Mn, P, S, Cr and Mo. CONSTITUTION:A welding rod consists of 0.05-0.15wt% C, 0.1-0.7% Si, 0.5- 1.4% Mn, <=0.035% P, <=0.035% S, 2-2.5% Cr, 0.9-1.1% Mo, <=0.3% rare earth element and the balance substantially Fe. This welding rod is added with the rare earth element which has high affinity to P, S and Sn and forms the precipitate stable in a 200-600 deg.C range in the grains and grain boundary in the stage of refining a raw material for the welding rod. The impurity elements in the deposited metal are immobilized as stable precipitate according to such welding rod, by which the diffusion of the impurities to the grain boundaries in the long- term use at a high temp. is prevented and the deterioration of the impact value is prevented.

Abstract: PURPOSE: To enable the defective particles in the magnetic toner to be surely removed by providing a mechanism of magnetically sucking the magnetic toner by a magnetical conveying means and conveying the same into the magnetic field of a generating means of electrostatic attraction force opposite from its attraction force.  
     CONSTITUTION: The magnetic toner 9 to be used for developing etc. of latent images is charged into a toner replenishing vessel 3. An insulating drum 1 is beforehand charged by an electric charging device 10. A nonmagnetic sleeve 4 and a magnet roll 5 are relatively rotated to draw out the magnetic toner 9 and convey the same in the sleeve 4. If in this case the electrostatic attraction force by the static charge on the insulating drum 1 and the magnetic attraction force by the magnet roll 5 are balanced, the defective particles in the toner are stuck on the insulating drum 1, but the normal particles are conveyed on the sleeve 4 and are recovered into a recovery box 7 by a scrapping plate 6. The defective particles stuck on the insulating drum 1 are decreased of electric charge by a destaticization device 8 and are thereby removed from the drum, after which they are recovered into a recovery box 7'.

Title: Apparatus for producing laminated sheet
Inventor: KURODA TAKETO
IPC: B32B15/08
Filed: 1995-04-14
Abstract: PURPOSE: To perform sufficient reaction at a time of lamination without generating voids by reducing the pressure in an airtight cover and applying uniform and stable heating high in reproducibility by a heating roll and proper tension to a prepreg to sufficiently heat the prepreg up to the interior thereof to effectively remove bubbles. CONSTITUTION: A prepreg 17 is indirectly heated on the outside of copper foil 16 by a heating roll 11b. Since an aritight cover 12 is reduced in pressure, the prepreg 17 is effectively reduced in pressure and defoamed by the heat from the heating roll 11b and tension. At this time, since the prepreg 17 is heated only on the side of the heating roll 11b, the surface of the prepreg is not previously dried and sufficient defoaming is performed. Subsequently, copper foils 15, 16 and the prepreg 17 are bonded and cured in the nip between heating rolls 11a, 11b under pressure to obtain a copper clad laminated sheet 13. Since the airtight cover 12 is reduced in pressure even at this time, air bubbles are not generated within the laminated sheet.

CONSTITUTION:A mixture of 15-97wt% of polyethylene having an ultimate viscosity eta of 1.5dl/g min. and not more than 5dl/g and 85-3wt% of paraffinic wax having a melting point of 40-120 deg.C and a molecular weight of 2,000 max are melted and kneaded at temperatures of 190-280 deg.C. This mixture is extruded from a die at the temperature higher than a melting point and not higher than 210 deg.C in an unoriented form. Next, it is orientated at least at an stretch ratio of more than 20 times as much. An orientated polyethylene obtained in the above- mentioned way has high tensile strength and also high elasticity. In addition, the orientated polyethylene is better looking through the blending of paraffinic wax because an stretch ratio which causes a whitening becomes higher.

Title: Method and device for controlling resistance welding
Inventor: KITSUNAI KEIICHIRO
IPC: B23K11/25
Filed: 1991-03-28
Abstract: PURPOSE:To obtain the constant-current control resistance welding device for preventing a splash generated at the time of finishing an electric conduction. CONSTITUTION:A power comparing part 44 compares a welding power set value Sp received from a welding power arithmetic circuit 36 with a power set value Qp from a power setting part 42, and outputs a power comparison error DELTAp. A power comparing part 48 compares a secondary current measured value Si received from a secondary power detecting circuit 30 with a current upper limit set value Qi from a current setting part 46, and outputs a current comparison error DELTAi. When an electric conduction is started, constant-power control is executed, therefore, a sequence control part 52 switches a switching part to 44 side, and gives DELTAp to an inverter control signal generating part 54. In the case of becoming DELTAi<=0 (a secondary current reaches the upper limit value) on the way of electric conduction, 52 is switched to the constant-current control, therefore, 50 is switched to 48 side, and DELTAi is given to 54. Unless DELTAi becomes <=0 on the way of electric conduction, 52 executes the constant-power control until the electric conduction is finished without switching 50.

IPC: H05K3/30
Filed: 1980-07-01
Abstract: PURPOSE: To miniaturize the whole device and attain high work efficiency by combining a rotary cutter and rotary grinding mechanism for removing burrs in one  unit.  
     CONSTITUTION: A disc-type cutting tool 6 is inlaid with a removable ring-type file 8, with its surface made slightly higher than surface of the cutting tool 6. Lead wires 2a, 3a, 4a and 5a of the electric parts 2, 3, 4 and 5 are attached by soldering to the printing base plate 1. As the cutting tool 6 rotates and the printing base plate 1 travels to the direction A, lead wires are cut by the tool 6 while burrs 10 are generated. These burrs are ground off by the file 10. The work efficiency is improved due to the simultaneous performance of lead wire cutting and grinding off of remaining burrs.
