Abstract: PROBLEM TO BE SOLVED: To make the power of irradiation light required for crystallization smaller by incorporating the metallic elements among the metallic elements constituting oxides with Zn of the elements to be incorporated into this protective layer at such a ratio as to have atomic% of a specific range of the entire amt. of these elements. SOLUTION: This medium has a transparent base material which allows the transmission of irradiation light, a recording layer which consists essentially of a chalcogen based alloy and the protective layer which is formed above and below the recording layer across this layer. The protective layer has at least one kind of ZnS and ZnSe and at least one kind of the oxides among SiO2 , GeO2 , SnO2 , TeO2 , ZrO2 , Al2 O3 , and Ta2 O5 . If the entire amt. of the metallic elements constituting these oxides with the Zn is defined as 100 atm.% the content of these metallic elements is so determined as to attain 35 to 65 atom.%.  The degradation in the thermal diffusion efficiency of the protective layer is resulted with the optical information recording medium constituted in such a manner and, therefore, the smaller power of the irradiation light necessary for noncrystallization is necessitated and the smaller energy for emission of the irradiation light is necessitated.

Title: Method for decreasing residual stress of large-sized hollow roll and refrigerant guide member used in this method
Inventor: SAKASHITA MOTOTAKA
IPC: B21B27/00
Filed: 1989-03-29
Abstract: PURPOSE:To economically decrease residual stresses by guiding a refrigerant to the inside surface of a roll by a the refrigerant guide members detained in the roll, controlling the amt. of the refrigerant heading toward the inside surface of the roll so as to be larger on the downstream side of the roll and thereby forcibly cooling the roll. CONSTITUTION:Plural annular bodies 7 having high rigidity for preventing the deformation of the roll at the time of a heat treatment are removable detained in the large-sized casting roll 1 to be cooled. The refrigerant guide members 8 for guiding a part of the refrigerant so as to diverge the same outward are provided in the annular bodies 7. The bar material 81 of the members 8 are so inclined that the downstream side of the refrigerant flow heads gradually outward, thus forming the guide surfaces 82 to guide the air flow toward the inside surface of the roll. A part of the supplied refrigerant comes into contact against the guide surfaces 82 of the members 8 and flows toward the downstream side while spreading toward the outside. The inside surface of the roll is thus effectively cooled. The amt. of the refrigerant heading toward the inside surface of the roll is increased more on the outlet side than on the refrigerant inlet side of the roll by the members 8, by which the increase of the refrigerant temp. toward the downstream is offset and the difference in the cooling rate between the inlet side and the outlet side is decreased.

Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To make variable the aspect ratio of the laser light beams emitted from a semiconductor laser and to irradiate an optical disk with laser light beams having sufficient power for a signal recording. SOLUTION: A semiconductor laser 1 generates laser light beams having a wavelength of 635 nm. A collimator lens 2 makes the laser light beams from the laser 1 parallel. An optical means 3 diffracts the light beams in the short axis direction of the laser light beams, that are made into parallel beams by the lens 2, to the outside the optical axis, makes the beams parallel, and emits the laser light beams having a prescribed aspect ratio. A half mirror 4 passes the laser light beams from the means 3 and reflects half of the reflected light beams at a signal recording surface 8a of an optical disk 8 toward the direction of a photodetector 7. An objective lens 5 converges the laser light beams and irradiates the surface 8a with them. A condenser lens 6 converges the laser light beams from the mirror 4. The photodetector 7 detects the laser light beams.  The means 3 is preferably arranged in the region where the laser light beams are made parallel.
