Title: Alkali zinc battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M4/24
Filed: 1983-07-06
Abstract: PURPOSE:To suppress elution and droppage of active substance at the circumference of plate by increasing the concentration of binding agent of active substance at the circumference of plate when compared with the central portion while arranging porous fluorine layer at the circumference of plate to form a zinc electrode. CONSTITUTION:Zinc oxide powder, zinc powder, cadmium oxide and fluorine resin powder binding agent are mixed while adding water to produce the first sheet 2. A frame-shaped second sheet 3 having higher concentration of binding agent than the first sheet 2 is formed. The first sheets 2 are arranged in the center on both faces of current collector 5 such as copper while second sheet 3 is arranged at the circumference and pressure molded. Thereafter, porous fluorine film 4 is arranged on the surface of second sheet 3 at the circumference and pressed again to form a zinc electrode. Consequently, permeation of electrolyte to the circumference of plate is limited to prevent elution and droppage of active substance at that portion resulting in improvement of cycle life.

Title: Image display device
Inventor: SEKIGUCHI TOMOHIRO
IPC: H01J29/46
Filed: 1993-05-26
Abstract: PURPOSE:To obtain a high quality of image by making the section form of the through hole of a drawing-out electrode in a form closed toward a cathode ray, and making the amount of electron beams passing through the through hole of the drawing-out electrode even. CONSTITUTION:Since the areas of different area amounts from both side surfaces are processed by an etching in the through hole 10 of a drawing-out electrode 3, the section form of the through hole 10 is made in a tapered form, and the form of the through hole is different at the surface 3(alpha) and the surface 3(beta). And the through hole at the 3(alpha) surface is provided at the position decided by the design, and thereby, the interval with the neighboring through hole 10 is constant. The electrons discharged from a cathode 2 are controlled to draw out only in the constant direction by the drawing-out electrode 3. But since the amount of the electron beams is decided by the form of the hole 10 at the 3(alpha) surface of the electrode, they are drawn out by making the amount of electrons even at all the holes regardless of the form of the 3(beta) surface of the hole 10. Furthermore, electrons passing through the hole 10 are pulled in evenly spatially without being pulled in deflecting from a constant direction in the space.

IPC: B23K9/00
Filed: 1988-05-21
Abstract: PURPOSE:To reduce the manufacturing stage of the title top plate by removing a protective sheet in the vicinity of a weld zone of a top plate main body extension plate and bending the extension plate and then, welding edges to be welded. CONSTITUTION:The synthetic resin protective sheet 2 stuck on a thin sheet metal material 1 is left as it is and the top plate main body extension plate 3 is cut out. The protective sheet 2 in the vicinities of the edges 5 corresponding to the positions to be welded of the extension plate 3 is then selected, peeled off and removed. Succeedingly, necessary bending places of the extension plate 3 are bent and then, the edges 5 to be welded of a top plate main body 6 and places to be welded of a basin, etc., are welded together. Since the protective sheet 2 of only the necessary places is peeled off, the second sticking stage of the protective sheet 2 at a working field is eliminated. By this method, the manufacturing stage of the top plate is reduced.

Title: Method for feeding document in automatic document feeding device
Inventor: TSUNODA KOICHI
IPC: B65H29/16
Filed: 1987-05-20
Abstract: PURPOSE:To surely carry out a paper discharging action after a copying action without any trouble even with a thick document or a thin document by temporarily feeding a document reversely after the end of an exposure action, removing and displacing a document stopping claw from a document conveying passage and, then, discharging the document. CONSTITUTION:When an exposure action is over, a conveying belt 3 is slightly reversed to feed a document 4 temporarily backward, thereby, retracting the end of the document 4 from the end 5a of a document stopping claw 5. By electrifying a solenoid 8, the document stopping claw 5 is loweringly rotated and removed out of a document conveying passage. At the time of this removing action, since there is no document 4 on the end 5a part, the removing action of the document stopping claw 5 will not be hindered even with a thick document 4, while the document stopping claw 5 will not draw in the end of a document 4 even with a thin document 4. Hence, the paper discharging action of the document 4 after the exposure action can be surely carried out without any trouble.

The detector 8 for sheet thickness and the detectors 9 and 10 for sheet temperature are equipped and are connected with the computer 11. For example, in the case where the preceding strip is thin (0.4mm) and the following strip is thick (0.6mm), in the first place, while being controlled to the set furnace temperature optimum to the strip of 0.4mm, the strip 1 passes. Then, before the strip of 0.6mm reaches the inlet of the first preheating zone 2, the actual furnace temperature of the quick heating zone 4 is brought to the optimum set furnace temperature for the strip of 0.6mm. And, just before the strip of 0.6mm reaches the inlet of the first preheating zone 2, the on-zone length of the first preheating zone 2 which has been reduced already, is returned instantaneously to its set on- zone length
