Title: Method for feeding zn ion during galvanizing
Inventor: YOSHIHARA YOSHIHISA
IPC: C25D21/14
Filed: 1986-04-15
Abstract: PURPOSE:To rapidly feed Zn ions to a galvanizing soln. at a low cost during galvanizing with an insoluble anode by adding an alloy of Zn with Cr, Fe, Cd, Co, Ni, Mo or Sn to the galvanizing soln. CONSTITUTION:During galvanizing with an insoluble anode, Zn ions are fed to a galvanizing soln. having a lowered concn. of Zn ions by dissolving metallic Zn in the soln. At this time, a Zn alloy obtd. by adding one or more among Cr, Fe, Cd, Co, Ni, Mo and Sn as elements having a higher standard potential than Zn to Zn by an amount within the range from the amount of such elements entering as inevitable impurities to the solubility limit is used as the Zn ion feeding source. Thus, the velocity of dissolution of metallic Zn is increased, so Zn ions are rapidly supplied to the galvanizing soln. to balance the concn. of Zn ions.

Title: Plastic working method
Inventor: MIZUNO MASASHI
IPC: B21C37/00
Filed: 1981-06-05
Abstract: PURPOSE:To improve working efficiency for various kinds of materials to be worked, by measuring the change of supersonic characteristics of the material, and performing plastic working at the temp. which exceeds the temp. measured at that point of time. CONSTITUTION:A material 1 to be worked is heated by applying electric current from an electric-heating source 6, and together, the change of supersonic characteristics accompanying the temp. rise is measured by a supersonic flaw detector 13. When the sudden change of supersonic characteristics caused by the sudden change of a structural state of the material 1 is detected, a prescribed heat energy is given by the source 6 to rise the temp. of it by a prescribed temp., by setting the temp. detected, at that point of time with a temp. detector 12, as a standard temp. The material 1 is, then, made to be in the optimum working temp. i.e. in a structural state of the highest degree of plasticity. Then cooling gas is blown against the material 1 from each air nozzle to make the material 1 possess a temp. pattern through its axial direction in order to make the material 1 possess a gradient in the degree of plasticity. Next, respective parts of the material 1 are stretched through the axial direction in different elongation ratios respectively, corresponding to a small diametral part and to the degrees of plasticity at respective parts, so as to form a taper rod of which diameter changes in its axial direction.

Title: Particle emitter, and field emission type device, and their manufacture
Inventor: WATANABE HIDETOSHI
IPC: H01J31/12
Filed: 1995-03-20
Abstract: PURPOSE: To improve electron emission efficiency. CONSTITUTION: The principal part of an electron emission source is constituted by coating a cathode electrode 13 with an insulating layer 15 and a gate electrode 14 in order, and forming a very small hole 20 through the gate electrode 14 and the insulating layer 15. The thickness t1 of the insulating layer 15 is less than 1μm, for example, 0.3μm. The top of the cathode electrode 13 is flat, and the section 13A exposed with the very small hole 20 functions as an electron emission face. When voltage is impressed between both electrodes, an equipotential level surface Em is made in roughly parallel with the electron emission face 13A on this face.  Since electrons e shifts in the vertical direction to this equipotential level, a great part of electrons e are emitted through the very small hole 20, and because the electron emission face 13A is flat, the quantity of emitted electrons becomes large.

Title: Electric furnace bottom gas-blowing apparatus
Inventor: ISHIHARA YOSHITAKA
IPC: C21C7/072
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent nonferrous metals such as lead and the like contained in a molten steel from intruding through a gas blowing hole as much as possible and facilitate to exclude the non-ferrous metals by raising gas pressure even if the nonferrous metals have entered by forming the gas blowing hole in a funnel like shape or an umbrella like shape. SOLUTION: A gas blowing hole 10 is formed in a funnel like or umbrella like shape. The gas blowing hole 10 having such a funnel like or umbrella like shape can blow gas at a higher speed at an upper side of an outer peripheral portion of the blowing hole than at a lower side so that molten lead having a tendency to adhere onto a top side of an outer peripheral portion of the blowing hole is scattered into outside stumping material and becomes easy to be absorbed. On the other hand, droplet molten lead adhering on a lower side of the outer peripheral portion of the blowing hole is difficult to be scattered but easy to move into the stumping material in vicinity due to vibration of a whole furnace body or vibration during gas blowing operation, and therefore the molten lead generally becomes difficult to adhere onto the peripheral portion of the hole. By raising blow gas pressure the lead intruding into the hole can be easily excluded.
