Title: Information signal recording medium and production of resin for information signal recording medium
Inventor: NISHIZAWA AKIRA
IPC: G11B9/06
Filed: 1987-04-30
Abstract: PURPOSE:To improve the reproduction characteristic of an information signal recording medium by forming said medium in such a manner that the medium contains substantially no incomplete polymer of a low mol. wt. bleeding on the surface of the medium. CONSTITUTION:This information signal recording medium is formed by decreasing the content of the incomplete polymer of the low mol.wt. bleeding on the surface thereof down to a level at which said polymer does not bleed on the surface i.e., at which the incomplete polymer is substantially not contained therein. Such information signal recording medium is obtd. by cleaning a resin for the information signal recording medium with an org. solvent in such a manner that the quantity of the extract from the resin for the information signal recording medium is decreased down to <=0.15wt.% of the resin for the information signal recording medium (30 deg.C extraction temp., 4hr extraction time and cyclohexane extraction solvent). Generation of drop-outs and groove skipping at the time of reproduction is thereby obviated and the reproduction characteristic is improved.

Filed: 1978-08-29
Abstract: PURPOSE: To prevent the bound of metal wire and the collapse of taken-up load by receiving the descending taken-up metal wire at arms descending in relation thereto on a turn table to reduce spirally descending angle.  
     CONSTITUTION: When arms 8 are raised to the upper position of screws 5 metal wire already taken-up a taken-up drum 1 is dropped on arms 8. The rotation of the drum 1 is transmitted to a carrier 4 (consisting of frame plates 4 1 , round bars 4 2  and horizontal plate 4 3 ) and a turn talbe 3 through a descending transmission pin 11. As the turn table 3 rotates, levers 7 abut against stoppers 10 on a truck to rotate ratchet gears 6 by one pitch and lower nuts 8 1  screwed on screws 5, i.e. arms 8. Thus, since the spirally descending angle of metal wire can be reduced, the bound of taken-up metal wire and the collapse of taken-up loads can be prevented.

Abstract: PURPOSE:To obtain a superconductor capable of providing a superconducting state at liquid nitrogen temperature using inexpensive materials by mixing powders of Bi oxide, Sr oxide, Ca oxide and Cu oxide, compression forming the mixed powders and calcining the resultant compact in an oxidizing atmosphere. CONSTITUTION:Powders of bismuth oxide, strontium oxide, calcium oxide and copper oxide are mixed and simultaneously compression formed to provide a compact, which is then calcined at 830-880 deg.C in an oxidizing atmosphere to provide the aimed calcined compact consisting of Bi-Sr-Ca-Cu-O.
