Title: Glass raw material melting method
Inventor: IIDA TETSUMI
IPC: C03B3/00
Filed: 1978-10-03
Abstract: PURPOSE:To efficiently melt glass raw material by supplying glass raw material layers on the surface of molten glass base material between glass cullet layers supplied to the surface of the base material adjacent to both side walls of a glass vessel kiln to prevent the supplied raw material from contacting the side walls. CONSTITUTION:Using raw material charger 6 glass raw material 7 and glass cullets 8, 8' are extrusion-supplied onto molten glass base material 2 in glass vessel kiln 1 in layers through inclined plate 13 from the central part of hopper 10 between partition plates 9, 9' and both ends of hopper 10, respectively, while regulating widths of cullets 8, 8' with supply width regulation plates 11, 11'. When raw material piles 14 are formed on material 2, material 2 is isolated from the heat of combustion flames and deprived of its heat owing to melting of piles 14. On the other hand, on material 2 adjacent to side walls 3, 3' of kiln 1 cullets 8, 8' are rapidly melted, and the molten cullet temp. becomes higher than the temp. of material 2. Accordingly, piles 14 shift toward the center of kiln 1 by means of convection currents formed.

Title: Welding equipment
Inventor: NAGASHIMA TOSHIJI
IPC: B23K9/028
Filed: 1987-05-21
Abstract: PURPOSE:To extremely easily fit a welding head by providing a clamp unit capable of holding the welding head fitting surface in parallel with a locus of a welding torch with the end face of a short pipe as a reference plane. CONSTITUTION:When a knob 8 is turned to the left, a shaft 5 is moved to the left and a disk 15 is also moved by being pressed to the left by a flange 23 of the shaft 5 and a lever 16 is moved to the inside by a function of an extension coil spring 21. As a result, the outside diameter of a strap 18 becomes smaller than the inside diameter of a nozzle 1 and it is made possible to insert the whole of the clamp unit 27 into the nozzle 1 or take it out therefrom. Then, the contact surface of a clamp main body 2 is surely pushed against the nozzle 1. When the knob 8 is turned to the right, the shaft 5 is moved to the right to move the disk 15 to the right via a compression coil spring 11 and the lever 16 is extended and the strap 18 strikes against the inside diameter of the nozzle 1. Further, when the knob 8 is turned, since the disk 15 cannot be moved by the lever 16, the compression coil spring 11 is compressed and the lever 16 is pressed against the nozzle 1.

SOLUTION: A switch 22 is arranged on a side surface of a cooking appliance main body 21 formed of a white plastic mold, and a reversible thermally discoloring layer 3 is formed on an upper surface of the cooking appliance main body 21 using thermally discoloring ink by dispersing a reversible discoloring material which presents red at 15 deg.C or lower and colorlessness at 15 deg.C or higher in an ethylene vinyl acetate copolymerization resin emulsion. When a transparent plastic pan 4 filled with, for example chilled water of 10 deg.C is placed on such as cooking appliance 2, the reversible thermally discoloring layer 3 is colored in red from colorlessness, and an aspect that a current-carrying heating element becomes red-hot in a red color can be visually sensed.  When the pan 4 is relowered from the cooking appliance 2, the reversible thermally discoloring layer 3 is restored to a condition before heating.

Abstract: PROBLEM TO BE SOLVED: To reduce the concentration of stress in an interlayer layer or a reinforcing material so as to increase durability when pressure is repeatedly received by arranging the winding directions of reinforcing materials to intersect each other in the inner and outer layer sides of spiral reinforcing layers. SOLUTION: The reinforcing materials 7 of spiral reinforcing layers 6 are arranged to intersect each other in the two layers of an inner layer side and the two layers of an outer layer side.

Consequently, the resistances R1 and R3 are connected to the head 6L in parallel, and the bias current permitted to flow on the head 6 is reduced, and a reduced bias current, and a compressed recording signal are overlapped on the terminal on one side of the head 6L, then it is permitted to flow on the head 6L.

Filed: 1991-05-28
Abstract: PURPOSE:To detect the cross buckle of extremely sheet that can not be detected by a traditional method and to surely correct it. CONSTITUTION:A linear image is projected in the vicinity of the outlet of work rolls 2, 3, the destorted image that is reflected from a sheet, is photographed with a telecamera 8 and image processing is executed. The case that the reflected image on the sheet is wavy and that this wave is moved in the breadthwise direction with the progress of rolling is judged as cross buckle and correction is executed. When rolling extremely thin sheet, cross buckle could not be detected and corrected. It has been the major cause of the decrease of yield, but yield is drastically improved by this invention.

Title: Die for extrusion
Inventor: IRITANI TAKASHI
IPC: B21C25/02
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To secure stable production of extruded products with improved surface properties by making the surface roughness of the part near the bearing surface of rear relief rising surface of the outlet of die for extrusion be <=specidied value. SOLUTION: The surface roughness of the rear relief rising surface 19 of the die outlet part is made at the maximum height (Ry) to be <=10 μm. Even when aluminum (alloy) of material to be extruded is subjected to displacement and vibration, the extruded products are not affected to surface roughness. Of the total height of H of rear relief rising surface 19, the height h (h<=1/3H) of the part near bearing surface 14 has only to be <=10 μm at the maximum height (Ry) of surface roughness. The part of the surface of rear relief rising surface to be finished to 10 μm is narrow, so the use of electric discharge machine capable of finishing the bearing surface 14 at a surface roughness Ry=2-3 μm will make the working easier. The boundary part between bearing surface 14 and rear relief rising surface 19 is not limited to the case of rectangular but allowed to be a circular surface.
