Abstract: An information recording medium is at least composed of a substrate having a microscopic pattern constituted by a continuous substrate of grooves formed with a groove portion and a land portion alternately, a recording layer formed on the microscopic pattern for recording information, and a light transmitting layer formed on the recording layer. The microscopic pattern is formed with satisfying a relation of P??/NA, wherein P is a pitch of the land portion or the groove portion, ? is a wavelength of reproducing light for reproducing the recording layer, and NA is a numerical aperture of an objective lens. The land portion is formed with wobbling so as to be parallel with each other for both sidewalls of the land portion. An auxiliary information based on data used supplementally when recording the information and a reference clock based on a clock used for controlling a recording speed when recording the information is recorded alternately.

Abstract: An interior illumination lamp 1 includes a housing 13 for mounting in an opening 12 formed in an interior member 11 of a vehicle, upstanding members 14 extending from a reverse surface 13a of the housing 13, bending members 15 connected to distal ends of the upstanding members 14, and a plurality of pairs of prevention portions 17 disposed adjacent the upstanding members 14. The prevention portions 17 lock the bending member 15 such that the interior member 11 is locked therebetween. Angle maintaining means 18 prevent the bending members from being bent too far so that the interior member is not compressed too much.

Abstract: An optical disc with a first recording layer has first data pits that include 14T data pits formed thereon in compliance with DVD-ROM specifications. A first reflective film is formed on the first recording layer, whereby the first reflective film has the relationship of 2.3?Pw/Tf?14 between the 14T pit width and the first reflective film thickness. The disc also includes a second recording layer having a first surface and an opposed second surface, whereupon second data pits are formed on the first surface in compliance with BD-ROM specifications. A second semi-transparent reflective film is formed on the second recording layer, while a transparent layer having opposed third and fourth surfaces is formed over the second reflective film at the third surface, such that the fourth surface allows a laser beam to pass therethrough in reproduction from either the first or second data pits.
