Title: Method for recovering thallium
Inventor: MINAMI CHIAKI
IPC: C22B7/00
Filed: 1989-11-06
Abstract: PURPOSE:To efficiently recover high-purity Tl by executing respective stages for adding an alkali carbonate to the caustic alkaline leaching liquid of Tl raw materials to settle and remove lead and executing the pH adjustment and two-stage reduction of the deleaded liquid under specified conditions. CONSTITUTION:The Tl raw material essentially contg. Pb, Zn, Cd, As, and Fe as impurities and the caustic alkaline soln. (NaOH, etc.) are brought into reaction at 40 to 70 deg.C liquid temp. and 9.5 to 10pH to obtain the leaching liquid. The alkali carbonate (Na2CO3, etc.,) is added to this leaching liquid to adjust the pH to 9.0 to 9.5 and to settle and separate the Pb. An acid is added to this deleaded liquid to adjust the pH to 1.5 to 2.5. A reducing agent (Zn, etc.) of 0.8 to 1.2 quiv. of the amt. of the Tl ions existing in this liquid is added to the liquid to form sponge Tl. The reducing agent of 1.8 to 2.2 equiv. of the amt. of the Tl ions contained in the final liquid of the prereducing stage is added to the liquid and the Tl is taken out as precipitate. This precipitate is further subjected repeatedly to the above-mentioned leaching stage or pH adjusting stage, by which the reducing agent, etc., contained therein are removed and the Tl is recovered.

A governing valve flow amount signal E2 is inputted into a functional device 26, corrected to a signal for actual steam flow amount, and the corrected signal E8 is outputted into an adder 22. A functional device 27 corrects a turbine bypass valve flow amount signal E3 to a signal for actual steam flow amount, and outputs the corrected signal E9 to the adder 22. Thus a stable pressure control is always made to increase control accuracy and responsiveness.

Title: Method for preventing adhesion of powder/grain to powder/grain relay chute inner wall and device therefor
Inventor: KOIKE NOBUHITO
IPC: B65G11/00
Filed: 1994-10-31
Abstract: PURPOSE: To remove the adhered powder/grain with a compact structure by suspending a plurality of powder/grain colliding bars on the opposite side of the upper side part to a powder/grain carrying conveyor discharge side in such a manner as to be capable of oscillating, and oscillating the powder/grain colliding bars at a prescribed timing by an oscillating device. CONSTITUTION: Powder/grain colliding bars 4b are arranged at small intervals, whereby the water-contained powder grain discharged from a conveyor is accumulated on the powder/grain colliding bar 4b surface and between the powder/grain colliding bars 4b. When the powder/grain colliding bars 4b are oscillated forward at any timing, a powder/grain 7 can be partially peeled and made to fall with the powder/grain 7 adhered between the powder/grain colliding bars 4b as the starting point. Thus, the powder/grain 7 is laid in the state slightly adhered to the powder/grain colliding bar 4b surfaces without being grown more than it, and can be stably carried over a long period, and the wear of the powder/grain colliding bars 4b is also hardly eliminated by the self-lining effect of the adhered powder/grain 7.  Further, an oscillating device 5 can be made compact because of the form for oscillating the powder/grain colliding bars 4b.

Abstract: PROBLEM TO BE SOLVED: To prevent breakage and deformation by melting snow accumulated on a roof, etc., by destroying a bridge of snow sliding down toward a gutter and accumulated by sprinkling water and melting this snow heated hot water. SOLUTION: A gutter 1 made in the same length of longitudinal length of a roof 6 is provided between lower edges of adjacent roofs 6 by bending both left and right side parts upward with a central part as their center and bending both of their left and right end parts upward. A roof 11 is warmed up by indoor heating of a green house 9 by actuating an airconditioner and snow making contact with a covered material 8 is melted. Accumulated snow gradually slides down on this covered material and is directed toward the side of the gutter 1. Thereafter, a head end part of accumulated snow makes contact with the gutter and makes a bridge on it, but the bridge is destroyed by sprinkling water of specified temperature burst out upward from each hole of a snow melting pipe 13 on the accumulated snow.  Water flowing down on the covered material and snow destroyed and entering a space part of the gutter 1 are melted by a hot water pipe 14 and temporarily reserved. Thereafter, it is heated by the hot water pipe 14 and becomes water, and snow continuously dropping is melted by this hot water.

Title: Magnetic disk substrate
Inventor: KAYAMOTO TAKASHI
IPC: B32B33/00
Filed: 1986-12-04
Abstract: PURPOSE:To provide excellent heat resistance together with the strength, surface accuracy and surface hardness necessary as a magnetic disk substrate by using titanium or titanium alloy as a core material and using ceramic or glass layers as surface hardened layers. CONSTITUTION:A core plate 1 consisting of the titanium or titanium alloy, insert materials 4 consisting of copper or copper alloy, nickel, titanium, nickel alloy or titanium alloy layers 3 and glass or ceramic layers 2 are laminated in this order. The copper or copper alloy has the poor adhesiveness to glass but since the insert materials 4 consisting of the sheets of the copper alloy are used on both sides of the films 3 of nickel, titanium, etc., having the high adhesiveness to the glass, the sufficient adhesive power is obtainable. The heat resistance of the substrate itself is greatly improved and the deterioration with age is simultaneously lessened by using the titanium or titanium alloy having a relatively small coefft. of thermal expansion as the core material.

IPC: B41J2/165
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer in which ejection performance of an ink jet head can be recovered appropriately. SOLUTION: A maintenance roll 30 is disposed along a press contact plate 20 being held at a specified rotary angle with respect to the nozzle face 116 of an ink jet head 10 and carried from a feed roller 31 to a winding roller 32. The press contact plate 20 is urged by a spring 21 to be pushed in the direction of the nozzle face 116 and pushed oppositely thereto by the tension at the time of winding. The rotary angle is determined in the vicinity of a press contact plate fulcrum 23 where both forces are balanced. A pneumatic pump for purge operation and the winding roller 32 are driven by a common motor. Since a protective plate is provided while projecting slightly from the nozzle face 116, the maintenance roll 30 does not collide against a nozzle directly.
