Title: Air intake part muffling structure for bubble generating bathtub
Inventor: HARAGA HISATO
IPC: A61H23/00
Filed: 1989-05-24
Abstract: PURPOSE:To reduce noise generated from a hole for sucking air by forming an air expansion chamber in which the space volume of the flow lower side is larger than that of the flow upper side in the middle of an air flow passage in an air intake part. CONSTITUTION:An air intake part is constituted mainly of a suction case 20 formed in a box type of a roughly rectangular shape, and in the middle of an air flow passage L of its inside, air expansion chambers 23-25 are formed, and the air expansion chambers 23-25 are constituted so that the space volume of the flow lower side becomes larger than that of the flow upper side of a flow passage L. Accordingly, when air flows into the upper and the lower expansion chambers from the upper and lower part muffling pipes 28, 29, the sound reduction quantity becomes large by enlarging an acoustic wave, weakening the acoustic energy strength, and reducing it by the end of the chamber. In such a way, the sound is nearly muffled to the same level as a noise caused by bubbles, and remarkable muffling effect can be attained.

IPC: B05D5/06
Filed: 1979-10-11
Abstract: PURPOSE: To provide the decorative sheet having a coordinative effect of visual rugged feeling and luster by a method wherein a cellular-duct pattern is printed to have on it much built-up of a curable transparent synthetic resifn coating.  
     CONSTITUTION: To express the wood grain pattern of a broad-leaved tree as shown in the figure, an ink is used to apply the wood grain pattern 3 of the broad- leaved tree onto a substrate 1 on which a broad-leaved tree undercolor layer 2 has been formed to have a metallic or pearl gray luster. Next, a wood-grain plate having harmonious tone is used to make a print with an ink added with a frosting agent and a binder of a curable transparent synthetic resin so that a cellular-duct pattern 4 will coordinate with the wood grain pattern 3. At this time, the curable resin coating 5 is used in an amount enough to form a large built-up pattern on the surface, by applying the coating 5 before the ink is sufficiently dried. Then, the coating is cured. The cellular-duct section raises up the transparent resin layer; the transparent resin coating permeates into the ink containing frosting agent. This produces an arch shaped raised frosted condition, thereby providing a decorative sheet in which a visual rugged feeling and luster effect are coordinated.

Abstract: PURPOSE:To obtain a product processed of flocked fablic, which possesses fine hand of the surface and excellent physical properties, by a method wherein two kinds of fibers whose cut lengths are different from each other is set and a part of a long fiber positioned ahead of a short fiber is fibrillated. CONSTITUTION:At least two kinds of fibers 3, 4 where fineness and cut lengths fall respectively within ranges of 0.3-10d and 0.2-5.0mm and the cut lengths are different from each other by 0.2mm or longer are set up. The fibers each set are joined to each other with an adhesive agent 5. A pick-up (g/cm<2>) of the adhesive agent joining the set fibers each other is 10Xmean cut length (mm)X(fineness (d) of fiber)<1/2>-50Xmean cut length (mm)X(fineness (d) of fiber)<1/2>. If the pick-up is little, joining strength of the fibers becomes weak and if the same is much, hand becomes hard. Then a part of the long fiber 4 positioned ahead of the short fiber 3 is fibrillated. With this construction, a product processed with flock setting possessing fine hand of the surface and physical properties such as excellent injury resistance is attained.
