Title: Information recording medium
Inventor: KODERA KOICHI
IPC: G11B7/24
Filed: 1985-06-19
Abstract: PURPOSE:To permit recording in an optimum state with specified recording power by forming a thin inorg. film to at least one side of thin recording films having the property to change with the phase by the effect of heat energy and forming said film in such a manner that the film is thicker nearer the center of rotation of a disk in the radial direction than in the part further therefrom. CONSTITUTION:The thin recording film 13 is formed on a disk substrate 12 made of polycarbonate having guide grooves 11 for tracking and the thin inorg. film 14 is formed at such a film thickness distribution in which the film is thick on the inside circumference and is thin on the outside circumference. This film thickness is so distributed that the sum of the heat capacity of the film 13 and the film 14 is proportional to the inverse number of the square root of the linear speed when the disk is rotated. A protective substrate 16 made of polycarbonate is further tightly adhered thereto via an adhesive agent 15, by which the disk is completed. The recording sensitivity is thereby improved from the inside circumference toward the outside circumference and the recording at the specified recording power is made possible while the highest C/N value is maintained regardless of the inside and outside circumferences.

Title: Sliding seal ring
Inventor: KRAUS REINHOLD
IPC: F16J15/38
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To reliably prevent explosive abrupt decompression in a space sealed by a seal ring by a medium impregnated into the seal ring resulted from a sudden drop in pressure around the seal ring irrespective of the material of the seal ring. SOLUTION: At least one surfaces of seal rings 4 and 7 are substantially wholly brought into close contact by elastic pre-load applied thereto with partition walls of respective assembly spaces 10 and 11 and selectively with a support face 12 of at least one support body 13 disposed in the assembly space. Since the seal rings 4 and 7 made of incompressible material thus substantially wholly receive uniform pre-load, even if the pressure around the seal rings 4 and 7 suddenly drops, the pressure inside the seal rings 4 and 7 is prevented from dropping suddenly to cause no explosive abrupt decompression by a medium to be sealed in inside the seal rings 4 and 7.
