摘要:
A resin composite metal foil comprising a metal foil and a layer of a block copolymer polyimide resin formed on one surface of the metal foil, a metal-foil-clad laminate using the above resin composite metal foil, a printed wiring board using the above metal-foil-clad laminate, and a process for the production of a printed wiring board comprising removing an external layer metal foil of a metal-foil-clad laminate and forming a conductor layer on an external layer insulating layer by plating, wherein the metal-foil-clad laminate comprises a layer of a block copolymer polyimide resin which layer is in contact with the external layer metal foil.
摘要:
A method of drying honeycomb structural bodies in which a dielectric drying is performed by moving the honeycomb structural bodies in a dielectric drying apparatus under a condition such that vapor is flowed in the dielectric drying apparatus, includes the steps of: covering a surrounding area of the honeycomb structural body by a sheet with a constant space; and performing the dielectric drying under such a condition.

To present an operating apparatus having features including ease of operation, controllability for preventing misoperation, small size, long life, and ease of assembling. The constitution includes a base unit as skeleton of operation unit, a key operation unit (13) having plural switches disposed at the front side of the base unit, a first design sheet (12) disposed at the front side of the key operation unit (13), printing patterns at positions corresponding to each switch, a display device (11) disposed at the front side of the first design sheet (12), having light function elements (11g) for transmitting and shielding the positions corresponding to the patterns on the first design sheet (12), and a second design sheet (10) disposed at the front side of the display device (11), having windows (10b) at positions corresponding to the light function elements. By manipulating a desired window, the light function element is set in light transmission state, and the pattern printed on the first design sheet is displayed in the window.
摘要:
In a method for kneading a silane coupling agent-blended rubber composition prepared by blending a natural rubber and/or a diene group synthetic rubber with silica and a silane coupling agent, a coupling reaction of the silica with the silane coupling agent is carried out in a temperature range of 130 to 140.degree. C.

The stain resistant cover composition of the present invention for colored rubber part of a tire is characterized by that it comprises water of 100 parts by weight, polyvinyl alcohol of 1.0 to 50 parts by weight, a vinyl acetate resin emulsion of 15 to 150 parts by weight (solid content), a surfactant of 0.5 to 5.0 parts by weight, and a silicon oil of 0.5 to 5.0 parts by weight. The stain resistant protective film of the present invention for colored rubber part of a tire is used as a stain resistant protective film for a colored portion in the side wall part of a tire, wherein the above protective film comprises polyvinyl alcohol, a vinyl acetate resin emulsion, a surfactant, and a silicon oil. The present invention can provide a stain resistant cover composition for colored rubber part of a tire used for preventing the colored part (side wall) of a tire from being stained by antioxidants bleeding from other tires, or dust and being scratched by contact with tires when rubber tires are transported or stored as they are piled up, and a protective film therefor.
摘要:
In a honeycomb catalytic converter having a metal case, a honeycomb catalyst mounted in the metal case, and a securing member used for mounting the honeycomb catalyst in the metal case and arranged between an outer surface of the honeycomb catalyst and an inner surface of the metal case, at lest one of an inlet portion and outlet portion of the honeycomb catalyst has a double cone structure in which an inner cylindrical member is arranged in the metal case. The honeycomb catalytic converter mentioned above can mount the honeycomb catalyst stably in the metal case for a long period of time even when exposed to high temperatures.
