  • Patent number: 7727426
    Abstract: Disclosed is an epoxy resin composition which is solid at ordinary room temperature, cures with excellent light resistance and heat resistance and minimal shrinkage, and is useful for encapsulating LEDs. The epoxy resin composition is characterized by comprising as an essential component an epoxy resin having an epoxy equivalent of 300-1000 g/eq and a softening point of 65-110° C. obtained by reacting a nonaromatic polycarboxylic acid (A) having an acid value of 100-250 mgKOH/g with a nonaromatic epoxy resin (B) having an epoxy equivalent of 100-400 g/eq. The nonaromatic polycarboxylic acid (A) may be obtained by reacting 1,4-cyclohexanedimethanol, 2,2-bis(4-hydroxycyclohexyl)propane, or 3,9-bis(1,1-dimethyl-2-hydroxyethyl)-2,4,8,10-tetraoxaspiro[5,5]undecane with methylhexahydrophthalic acid or hexahydrophthalic acid.

  • Patent number: 6611091
    Abstract: A fluorescent lamp has an amalgam container settled inside an exhaust pipe extending from an end portion of a bulb to which electrodes are attached at both end portions. The amalgam container contains amalgam inside and has an opening portion through which the contained amalgam cannot go out and a part for determining the position of the amalgam, wherein the opening portion is located on the side where the exhaust pipe is cut and sealed. This configuration makes it possible to prevent the amalgam from outflowing into an exhaust equipment. In addition, the mercury vapor pressure is maintained optimally, and high luminous efficiency is obtained.

  • Patent number: 5154768
    Abstract: The solar heat-shielding paint composition of the present invention contains a solar heat-shielding pigment having a grain size of 50 .mu.m or less in a proportion of from 2 to 60% by weight of the solid content of the composition as a part or all of the pigment. The solar heat-shielding paint-coated structure having an outermost overcoat layer made of the said paint composition on the structure base displays an excellent solar heat-shielding effect and has a long-time durability with no problem of environmental pollution. The overcoat may be colored in any desired color to give a beautiful outward appearance. The coated structure is extremely useful as an outdoor structure, for example, marine structures such as decks or tanks of ships, as well as land structures such as architectures of petroleum tanks, houses, buildings, storehouses or gymnasia, and cars, tank lorries and refrigerator containers.
