Abstract: PURPOSE:To obtain an optical recording medium substrate which can be rotated stably at a high speed, namely, can transfer data at a high speed, by constituting it of a metallic material, and transferring an information pattern consisting of a transparent material to the surface of the substrate. CONSTITUTION:A resist film 2 which has been formed on a master disk substrate 1 such as glass is pre-baked, and thereafter, an exposure for writing an information pattern is executed, and subsequently, an exposure range of the resist film 2 is developed by a suitable developer and melted and removed, by which an optical recording medium duplicating master disk is obtained. A suitable transparent transfer pattern forming material 3 is applied and coated on the information pattern surface of the master disk, and also a transparent stamper substrate material, for instance, glass, acrylic resin, etc. 4 is superposed on this transparent material 3. Subsequently, in case when the transfer pattern forming material 3 is a 2P resin of ultraviolet ray curing type, the layer 3 is hardened by irradiating an ultraviolet ray on a unified object of the master disk part and the stamper part and also made to adhere to the substrate 4. After the hardening of the transfer pattern has been completed, a transparent stamper is obtained by separating the stamper part from the master disk part.

Title: Objective lens and optical head using the same
Inventor: SHIMANO TAKESHI
IPC: G11B7/135
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To inexpensively and accurately reproduce optical disks having their different substrates in thickness without a loss of a quantity of reproducing light by adding an annular phase shifter for reducing aberrations of both two coverged spots which are different in wavelength to an objective lens to form one body. SOLUTION: At the time of reproducing the CD having its substrate 1.2mm thick with a laser beam of a wavelength 780nm, by adding a doughnut-like annular phase shift area 101 to the objective lens for the DVD, a spherical aberration caused by a substrate thickness difference 0.6mm from the DVD is reduced. Moreover, by adding an opposite annular shifter of a negative phase -ϕopposite to a phase difference ϕ generated at the time of reproducing the CD to an area other that the annular phase shifter area in order that a phase is shifted only by the CD, so as not to increase the aberration at the time of reproducing the DVD, the aberrations of the converged spots on the CD and the DVD are reduced. Furthermore, by combining divided lenses, optimization can be carried out on the substrate thickness.

Abstract: PURPOSE:To make it possible to use a low temperature heat medium, such as water as a high temperature heat medium, by connecting a high pressure holder to which non-condensable gas is sealed to a flow passage where high temperature fluid is flowing, and applying pressure to the liquid flowing in the passage. CONSTITUTION:An accumulation tank 1 is provided with a heat exchanger section 3 which transmits the heat accumulated in an accusation member 2 inside the accumulation tank to a heat medium inside, and a closed-shaped circulation passage 5 for heat medium including a heat exchanger section 4 which exchanges heat between a fluid to be used by heating and a heat medium. At the top of the ring-shaped passage 5 is connected a high pressure holder 6 to which none-condenced gas, such as nitrogen gas is sealed. A safety valve 7 is connected to this high pressure holder 6. It is desirable that all parts excluding the heat exchanger 4 between the accumulator 1 in the ring-shaped passage and the fluid to be used should be coated with insulation 8. On the way of the ring-shaped passage 5 installed is a pump which drives the heat medium if required. If a pressure which exceeds the pressure required to maintain the liquid phase is applied to the pressure prevailing in the ring-shaped passage, the vaporization in that part can be inhibited.
