  • Patent number: 9533439
    Abstract: A resin-molded component includes a thin wall portion, and a rib-like projection configured to protrude from a back surface of the thin wall portion. The rib-like projection includes a plurality of plate-like projections arranged to be spaced from one another. Each of the plurality of plate-like projections is arranged such that an angle formed between a line connecting a point on a longer side of a bottom surface thereof to a gate provided in the thin wall portion and the longer side of the bottom surface thereof is within a range from 10 degrees to 80 degrees.

  • Publication number: 20150318017
    Abstract: To provide a method for cleaning a glass substrate in which aggravation of surface roughness of the glass substrate in alkali cleaning is suppressed and cleaning performance is improved. In one or a plurality of embodiments, this invention relates to a method for cleaning a glass substrate, including bringing a detergent composition into contact with a glass substrate to be cleaned. The detergent composition containing an amine including 1 to 10 nitrogen atoms and an inorganic alkali, the amine content is in a range of 5.00 mass % to 70.00 mass % relative to the total mass of components of the detergent composition other than water, the glass substrate to be cleaned is a crystallized glass substrate, and a pH of the detergent composition during cleaning is in a range of 9.00 to 11.50.

  • Publication number: 20090151299
    Abstract: The present invention provides a modular natural stone wall system and method of making that provides a modular solution that is able to build true natural stone walls in an efficient manner. The invention dramatically reduces the cost, time, and labor resources needed to build natural stone walls. It makes natural stone walls more affordable to consumers, more efficient for contractors to install, and eases the concerns surrounding skilled masonry labor shortages. In one particular embodiment, the present invention is created by first pre-designing multiple unit surfaces, natural stones are pre-cut; design is laid out on template; the back of pre-cut natural stone pieces and multiple block surfaces are preferably roughed out, bonding material is added and the natural stones are affixed to the block. As a result, the surface of the modular blocks are covered with natural stone prior to installation.
