Abstract:
A hopper having a passage through which a medicine can be passed downward is provided. A part of a lower portion of the hopper is a deformable portion having flexibility, and the deformable portion is deformable so as to open and close the passage. According to this configuration, the deformable portion that is a part of the hopper is deformed to open and close the passage. Thus, there is no portion such as an opening and closing plate on which the medicine remains, thereby preventing a gap in which the medicine remains from being formed in the hopper, and preventing the medicine from easily remaining in the hopper.
Abstract:
Provided is a metal foil laminate that: has heat resistance; has high reflectance in the visible light range; has little decrease in reflectance in environments with a high-temperature thermal load; is compatible with large surface areas; and can be used for printed circuit boards for mounting LEDs that have excellent adhesion with metals. The metal foil laminate is characterized in that: a laminate has metal foil on at least one side of a resin layer (A) containing a polyorganosiloxane and an inorganic filler; the 90° peel strength between said resin layer (A) and said metal foil is at least 0.95 kN/m, and the mean reflectance at wavelengths of 400 to 800 nm on the surface that is exposed when the resin layer (A) is exposed by peeling and removing said metal foil is at least 80%; and the decrease in the reflectance at a wavelength of 470 nm after being treated with heat for 10 minutes at 260° C. is not more than 5%.
Abstract:
Organosilicon composites are described, comprising 30 to 90 vol. % of a cured organosilicon copolymer derived by curing an organosilicon polymer having, in the same copolymer, silicon-containing repeating units comprising a silicon hydride and silicon-containing repeating units comprising a C1-10 ethylenically unsaturated group; and 10 to 70 vol. % of a dielectric filler. The composites are used in the manufacture of circuit subassemblies.
Abstract:
In one implementation, a method of fabrication of stretchable electronic skin is provided. The method may include receiving an elastic material net. An elastic conductor mesh is formed on the elastic material net. A device is electrically bonded to the elastic conductor mesh. The implementation may further include forming a mold comprising a net pattern on a substrate and creating the elastic material net by coating the mold with an elastic material precursor, and then removing the elastic net from the substrate with the elastic conductor thereon. In one embodiment, a stretchable electronic skin including a net structure having a non-conducting elastic material with an elastic conductor mesh formed on the non-conducting elastic material, and a device electrically connected to the elastic conductor mesh.
Abstract:
