  • Patent number: 11709312
    Abstract: A planar light source includes: a light guide member, a light source including a light-emitting element and a first light adjustment member and being disposed in a first hole of the light guide member, a first light-transmissive member disposed in the first hole between a lateral surface of the light source and the light guide member and on the light source, and a second light adjustment member disposed on the first light-transmissive member. A transmittance of the first light-transmissive member is higher than a transmittance of the first light adjustment member and a transmittance of the second light adjustment member with respect to light emitted from the light source. The first light-transmissive member includes a first light-transmissive portion 1ocated between the first light adjustment member and the second light adjustment member, and a second light-transmissive portion 1ocated between the lateral surface of the light source and the light guide member.

  • Patent number: 7258919
    Abstract: The purpose of the present invention is to provide an acrylic pressure sensitive adhesive and a pressure sensitive adhesive tape preferable to be used for adhesion and fixation of members to be used in closed space of such as a vehicle, a housing where odors become a problem; or in the side of electronic appliances where volatile gases become a problem and also relates to a vehicular air conditioner unit produced by using them. The present invention relates to an acrylic pressure sensitive adhesive, which has 500 ppm or lower of volatile component concentration A calculated by the following equation (1), when the acrylic pressure sensitive adhesive is heated at 90° C. for 30 minutes: volatile component concentration A (ppm)=volatile component content X (?g)/pressure sensitive adhesive weight Z (g) before heating ??(1) in the equation (1), the volatile component content X is an amount measured by conversion into toluene.

  • Patent number: 7016749
    Abstract: A product design CAD data reconstruction unit 50 reconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database 90. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database 90, and the product design CAD data is corrected along a design surface of the corrected design.
