Title: Treating method for molten cast iron
Inventor: UMEZAWA KAZUMASA
IPC: C21C1/04
Filed: 1978-12-15
Abstract: PURPOSE:To desulfurize and to dephosphorize cast iron with the same refining agent, by desulfurizing the desiliconized cast iron with a refining agent composed of CaO, CaCl2, KCl, etc., then by increasing the oxidizing power of the molten slag. CONSTITUTION:Molten cast iron is primarily desiliconized to 0.03-0.25% Si. Then 2-10kg refining agent composed of 1pts. wt. CaO, 0.2-0.5pts. wt. chloride,  e.g., CaCl2 or KCl is added to 1 ton cast iron to form basic slag. The mixt. is  agitated sufficiently by gas-bubbling to remove 70% of S contained in the molten  cast iron into the above-described molten slag. Subsequently, an oxygen source such  as oxygen gas, mill scale etc. is added so as to increase FeO content of the molten  slag, and to oxidize P in the cast iron to P2O5. Hereby, S contained in the molten slag is oxidized and removed by the oxidation heat of Si contained in the molten cast iron, i.e., the cast iron is subjected to evaporation dusulfurization, preventing resulfurization which otherwise would be caused by the increase in acidity of the molten slag. P2O5 is fixed to the slag with CaO contained in the basic slag, thus the cast iron is dephosphorized.

Title: Blow molding extrusion head
Inventor: JIEEMUSU RUISU SUROON
IPC: B29C48/475
Filed: 1992-06-15
Abstract: PURPOSE: To prevent the material for molding extrusion from thermal degradation and to form a parison with uniform wall thickness in a blow molding extrusion head. CONSTITUTION: A movable plunger 30 is slidably mounted in a distributor head 17 which receives the melt at the inlet end part 41 of a channel 40. The distributor head 17 directs the melt toward the end part 42 of the channel 40 along the channel 40 to fill an accumulator chamber 52 with the melt as a result. The plunger 30 is receded by filling the accumulator chamber 52 and thereby filling the accumulator chamber 52 is facilitated. The channel as defined by the adjacent circumferential wall and the curvilinear contour on the distributor head 17 defines a smooth integral flow channel that is curvilinear in cross section.

Title: Quartz glass optical fiber and its production
Inventor: MORITA YUKIO
IPC: C03C25/10
Filed: 1987-06-22
Abstract: PURPOSE:To prevent crack by confining the diameter of the air bubbles remaining in a cured primary coating layer to <=20mum. CONSTITUTION:The presence of the air bubbles in the primary coating layer consisting of an uncured UV curing type org. high-polymer material is substantially forbidden. Namely, the air bubbles in the compsn. for forming the primary coating layer are removed until the size of the air bubbles in the primary coating layer decreases to about <=20mum. Means for removing the air bubbles are exemplified by deaeration under a low pressure condition such as vacuum evacuation, heating and standing still. Since the air bubbles in the cured primary coating layer are thereby diminished as far as possible, the generation of the crack is prevented.

Title: Method and apparatus for forging press
Inventor: OBATA TOSHIHIKO
IPC: B21J1/02
Filed: 1988-06-24
Abstract: PURPOSE:To straighten the bend of a material with a small force and to press a straight material by correcting the deformation of the material based on press-forming while the material fed is pressed by dies. CONSTITUTION:When dies 1a, 1b are brought into contact with a material 2 fed between 1a, 1b and are rolled down, the material may be curved. When the material is fed and rolled down in sequence without correcting this curved part, the material 2 is bent in the form of a banana. At this time, the side guide 4a pushes the material 2 and straightens the bend. As a result, when rolling reduction has been completed, the rolling reduction surface 1a', 1b' of the dies 1a, 1b and the contact surface 4a', 4b' of the material with the side guides 4a, 4b are the same surface and consequently the material 2 is straightened. In this case, since the material 2 is rolled down and formed by the dies 1a, 1b while the material 2 is being deformed, the bend is corrected and consequently a small force is enough for correction.
