Patent JP-H0664664-A (JP)
Title: Packaging material
Inventor: KAGEYAMA MASAYUKI
IPC: B65D65/40
Filed: 1992-08-10
Abstract: PURPOSE:To keep the contents of a package free from changes and degradation in quality over an extended period of time by a method wherein the free space in the package and the oxygen concentration of the contents are reduced by the combination of a specific oxygen absorbing agent and the packaging material. CONSTITUTION:At least a kind of oxygen absorbing substance selected from porphyrins, ascorbic acid, and ascorbic acid salt is added to the polyester resin having a melting point of at most 180 deg.C. Although the amount of the oxygen absorbing agent contained varies with its deoxidation ability and its kind, in general, 0.01-20 pts.wt. of the oxygen absorbing substance is preferably contained in 100 pts.wt. of the polyester resin. The oxygen absorbing agent contained in an amount of less than 0.01 pts.wt does not produce any sufficient oxygen absorbing effectiveness and this effectiveness remains unchanged, even if the amount exceeds 20 pts.wt. If the melting point of the polyester resin exceeds 180 deg.C, the oxygen absorbing agent is thermally decomposed upon formation into film or container during or after addition of the oxygen absorbing substance to the molten resin. The packaging material thus formed is laminated to the innermost layer of the product.

Title: Recording medium for reversible optical record and method of regenerating optical recording medium
Inventor: SHIYUTEFUAN IZERUBORUN
IPC: G11B7/24
Filed: 1990-09-07
Abstract: PURPOSE: To obtain a high contrast by forming a recording medium in such a manner that the reflection contrast of the light polarized perpendicularly to an incident surface is larger than 0.5 and the sum of the reflection capability to the light polarized parallel and perpendicular thereto is at least 8%. CONSTITUTION: A Te70 Ge30 layer of a memory layer and an SiO2 layer which is a transparent layer are formed on a glass substrate. The reflection contrast in the wavelength of incident light to the light polarized perpendicularly to the incident surface is larger than 0.5. Namely, the component polarized perpendicularly to the incident surface hardly reflects or does not reflect at all at either of two changeover states. Simultaneously, the component polarized parallel therewith still reflects powerfully and, therefore, only the parallel polarization component or the sum of the parallel and perpendicular polarization components is usable for maintaining ordinary focusing and tracking control servo functions.

Title: Manufacture of metallized film capacitor
Inventor: HIKINO JUNICHI
IPC: H01G4/18
Filed: 1989-09-12
Abstract: PURPOSE:To achieve improvement in capacitor withstand voltage by a method wherein a non-metallized section is formed on a metallized film using a laser, and when one or a plurality pieces of film capacitor basic material are formed, the burr part of metal generated when the non-metallized section is formed is crushed. CONSTITUTION:A metallized film 2 is formed by vapor-depositing Al(Aluminum) on one side of a dielectric film. When the film 2 is wound up in the direction of a plate laminated layer reeling section 6 from a metallized film original sheet 1, a laser margin process (formation of non-metallized part) is conducted. Subsequently, the metal burr section 8, which is generated when a laser margin process is conducted between a rubber roll 4 and a metal nip roll 5, are crushed and the film 2 is rolled up on the plate laminated layer reeling section 6. The metal burr section 8 has the upheave height of about 0.5 to 2mum, and also as it is hardened by the irradiation heat of laser, the heat is not added to the base dielectric film. As a result, the dielectric film is not softened, and it is not damaged substantially even when it is nipped by the rolls 4 and 5.

Abstract: PROBLEM TO BE SOLVED: To provide a cutting device which can cut easily and smoothly even the raw material with a thin plate thickness. SOLUTION: In this cutting device, a shear angle θ1 is made on the corner 12B of a punch 12. Thereby, the cutting of a raw material 10 is carried out smoothly and easily without generating a dangling at the cutting time even if the clearance of the angle parts 12B, 52A against the plate thickness of the thin raw material 10 is large. As the angle part 12B is nearly in a point contact state against the raw material 10, the load added to the raw material 10 becomes small and the cutting of the raw material 10 is carried out smoothly and easily. Therefore, as the folding by the dangling when the thin raw material 10 is cut as usual and a halfway cutting are prevented, the work efficiency is improved and the waste of the raw material 10 is prevented.
