摘要： When a driving shaft rotates, a piston (9) revolves around the driving shaft in a cylinder room (6a) with supported by a swing bush (32) as a supporting point through a blade (31). Discharge ports (22) are formed in a front head (7) and a rear head (8) respectively and are disposed to be located in the proximity of the blade (31) and to communicate with a high pressure room. A semicircular portion of the discharge port (22) overlaps with the swing bush (32) and the cylinder (6). A pair of upper and lower cut parts (41) are each formed by cutting away an outer peripheral edge of the swing bush (32) and an inner peripheral edge of the cylinder (6) which are overlapped with the discharge port (22).

摘要： An optical information recording medium of the present invention includes a transparent substrate and a multi-layered film formed on the transparent substrate. The multi-layered film includes a lower protective layer, a recording layer that changes reversibly between different states detectable optically by irradiation of light beams, an upper protective layer, an intermediate layer and a reflective layer in this order from the side near the transparent substrate. Of the upper protective layer, the intermediate layer and the reflective layer, the heat conductivity of the layer closest to the recording layer is the smallest of the three layers, and thereafter the heat conductivities of the others increase with increasing the distance from the recording layer, and the thickness of the recording layer is from 4 nm to 16 nm. In addition, a light absorption layer can be used in place of the intermediate layer. In this case, the difference between the refractive index of the light absorption layer and the refractive index of the reflective layer is 2 to 6, and the thickness of the reflective layer is not smaller than the thickness of the light absorption layer. Alternatively, the light absorption layer has a thickness d, in a range of 0.1 &lgr;/(n1·k1)≦d1≦1.0 &lgr;/(n1·k1), where n1 is a refractive index and k1 is an extinction coefficient of the light absorption layer.

摘要： The present invention relates to a production process and a production apparatus for the optical information recording media comprising a material thin film which exhibits a reversible change of the optical characteristics by the irradiation of an energy beam such as a laser beam on the substrate. By dropping the emission strength instantly to the virtual zero level after having the emission for a specified time in conducting the initial crystallization process, both a large irradiation power and a short irradiation time can be achieved to reduce the various thermal damages. The charging time can be shortened. In the production of optical information recording materials with single side structure, in particular, by applying an annealing process in combination with a formation process of the resin protection layer or a recording thin fil initialization process, the warp or distortion of media caused by the contraction of the ultraviolet ray curing resin layer or the recording thin film layer can be reduced or corrected to realize an optical information recording medium having excellent servo characteristics. Further, by having at least one of two media to be affixed with a transmissivity of an ultraviolet ray of 3% or more as a method to comprise an optical information recording medium with double sides structure not liable to have a warp or distortion, an ultraviolet ray curing resin can be used as an adhesive, resulting in simplifing the production process.

摘要： On a substrate, a recording layer which reversibly transforms between two states with different optical properties--a crystalline phase and an amorphous phase--by the irradiation of a laser beam, a first and a second dielectric layer on the bottom and the top surfaces of the recording layer, and a third dielectric layer on one surface of the first or the second dielectric layers and on the opposite side with respect to the recording layer are successively laminated, thus preparing an optical information recording medium. The third dielectric layer has a smaller coefficient of thermal expansion than the first and the second dielectric layers, so that the thermal deformation of the first and the second dielectric layers is reduced and the mass transfer of the recording layer is controlled. As a result, the overwrite cycle characteristics of the optical information recording medium are excellent.

摘要： In a phase change optical disk wherein a first heat-resistant protection layer, an optical active layer showing a reversible phase change between a crystal state and an amorphous state, and a second heat-resistant protection layer are laminated on a substrate in this order, both of the first and the second heat-resistant protection layers are made of a mixture of a chalcogenide and a vitrification accelerating material. Further, a mixture ratio of the vitrification accelerating material in the second heat-resistant protection layer is larger than that in the first heat-resistant protection layer. Thereby, it becomes possible that the first heat-resistant protection layer has the mixing ratio which gives the refractive index value bringing suitable optical properties, while the second heat-resistant protection layer has the different mixing ratio which gives the thermal conductivity bringing suitable thermal properties. As a result, a phase change optical disk having high sensitivity, improved life characteristics in repeated record/erasure operations and wide production margin is provided.
