摘要:
In an optical pickup device for recording information onto and/or reading out information from an optical recording medium, comprising a light beam source for generating a light beam to be projected toward the optical recording medium, and a light beam detector for receiving the light beam reflected by the optical recording medium so that the information is read out from the light beam after reflected by the optical recording medium, a container houses therein the light beam source and includes an aperture through which the light beam proceeds toward the optical recording medium, and a light beam guide member is mounted on an outer surface of the container and covers the aperture to guide the light beam after reflected by the optical recording medium toward the light beam detector.
摘要:
An optical pickup device has a single light beam path in which at least one or either of a plurality of kinds of light beams (different from each other in, for example, wavelength) for respective recording densities and/or recording-medium-thicknesses proceeds toward a surface of an optical recording medium and proceeds to a light beam detector after being reflected by the surface.
摘要:
An optical pickup device has a single light beam path for common use in treating or passing either of a plurality of kinds of light beams for respective recording densities and/or recording-medium-thicknesses different from each other, in other words, at least one or either of the plurality of kinds of light beams is introduced into the common single light beam path which may includes a single quarter-wave plate and/or single collimator and/or single objective.
摘要:
In an optical pickup, an optical guide member is provided in an optical path of light from a light source, and has a plurality of inclined surfaces inclined with respect to a light beam emitted from the light source. A light-receiving element is provided for receiving light and for converting the received light into an electrical signal. The optical guide member and the light-receiving element are contained in a packaging member. The light beam from the light source is reflected by the plurality of inclined surfaces of the optical guide member, and then are directed to a recording medium. The reflected light from the recording medium is directed to the light-receiving element. At least one of dry air and inert gas such as nitrogen gas is charged in the interior of the packaging member at a pressure of 0.5 atm to 1.5 atm, thereby preventing the optical characteristics from being degraded.

The present invention herein discloses a method for purifying human serum albumin, which is characterized in that it comprises the steps of heat-treating a human serum albumin-containing solution including impurities originated from a host cell, in the presence of a divalent cation such as calcium ion, magnesium ion, nickel ion, cobalt ion, iron ion and zinc ion to thus selectively allow the impurities to undergo agglutination. The present invention also provides the highly purified human serum albumin prepared by the foregoing method.

A surface lighting device has one single light source and a light-guide-board. The board includes a light-guiding-section and a light-emitting-section. A shorter side of the light-guiding-section is not more than 8 mm, and an area of the light-emitting-section is not less than 500 mm2. The light-emitting-section has the following features: (1) a ratio of min. luminance vs. max. luminance of is not less than 0.3; (2) an average luminance ranges from 1 cd/m2 to 200 cd/m2, and (3) a change value in luminance per unit length is not more than (average luminance)×100 cd/m3. Employing plural light-emitting-elements in the light source allows the lighting device to produce versatile colors. The light source, light-guide-board and a holder are structured and shaped in optimum way, so that unevenness in luminance of the device is reduced. An LCD unit incorporating this surface lighting device increases its display quality, and a portable terminal incorporating this LCD unit produces easy-to-lead display.

A printer includes: a recording section for recording information on a recording medium; a medium carrying mechanism for carrying the recording medium on which information has been recorded by the recording section; a medium accommodating section extending in a vertical direction or in a slanted vertical direction for accommodating the recording medium carried by the medium carrying mechanism; and pusher means for pushing the recording medium carried by the medium carrying mechanism into the medium accommodating section.
摘要:
With a semiconductor device embodying this invention, a semiconductor element is clamped between a pair of electrodes in a housing. A hollow cylindrical explosion-proof member is so set in the housing as to enclose the semiconductor element. The hollow cylindrical explosion-proof element is prepared from soft elastic material capable of absorbing the force of the explosion of the semiconductor element.
