摘要:
A single-chip microcomputer includes a microprocessor, a subprocessor for performing peripheral functions, an external port for controlling an input/output operation from/to an external device and a multi-functional logic-in-memory for inputting a plurality of data from at least one of the microprocessor, the subprocessor and the external port and selecting write data from among the plurality of data in accordance with predetermined priorities.
摘要:
A light scattering material is prepared by mixing with and dispersing in a transparent elastomer matrix particles of a transparent material. The matrix has a Tg of lower than room temperature and the transparent material has a different index of refraction form the matrix.
摘要:
A light guide includes a hollow tubular cladding of a fluorocarbon resin having a methacrylic or acrylic monomer graft polymerized inner surface. The cladding is integrally filled with a core of a methacrylic or acrylic resin which is polymerized to the graft polymerized surface.
摘要:
An optical waveguide hose includes a hollow tubular cladding made of a material having rubber elasticity at the service temperature of -50.degree. to 150.degree. C. and having a lower creep. The cladding is filled with a core fluid having a higher index of refraction than the cladding and closed with sealing plugs at opposed open ends. The hose is improved in flexibility and handling, prevents gas penetration into the core fluid, maintains transparency at widely varying temperature over a long time, and is lightweight and inexpensive.
摘要:
In an optical waveguide comprising a transparent cladding (1) filled with a transparent liquid core (2) having a higher refractive index than the cladding, a liquid consisting of an oligomer having a phosphazene skeleton, typically phosphazene oil is used as the core (2). The waveguide is well resistant to heat and weathering, ensures stable performance in a wide temperature range over a long period of time, and provides good light transmission in a wide wavelength range covering the UV, visible and IR spectra.
摘要:
A rubber hose comprising an inner tube of synthetic resin, a silver or silver alloy thin film sputtered or ion plated on the inner tube, and a rubber layer heat cured to the thin film through adhesive exhibits low gas and solvent permeability and high flexibility while maintaining such properties even on angular bending.
摘要:
A sandwich glass comprising glass plates and an intermediate layer interposed therebetween is disclosed. The intermediate layer is formed by crosslinking or photocrosslinking a resin composition comprising an ethylenevinyl acetate copolymer and an organic peroxide or a photosensitizer under heating of the resin composition above the melting point of the copolymer.
摘要:
Only an outer surface of an unvulcanized rubber sheet is preliminarily crosslinked by irradiating an infrared ray or a far infrared ray to the unvulcanized rubber sheet prior to subsequent final vulcanization, whereby the occurrence of rubber spew and rubber flash is considerably suppressed at the vulcanization step.
摘要:
A rubbery composite material comprising a substrate and a rubber composition bonded thereto is prepared by metallizing a substrate with a thin film of zinc, copper, cobalt or an alloy thereof by dry plating such as vacuum deposition, ion plating, DC magnetron sputtering, bipolar sputtering, and RF sputtering processes, and pressing a vulcanizable rubber composition to the metallized substrate under heat and pressure to effect vulcanization bonding.
摘要:
Means for changing-over address signals is provided in an address input portion, and the order of the signals to be input to an address decoder is changed according to external control signals. Alternatively, a reading output circuit is provided which reads data in bit unit different from that of the writing input circuit. Thus, data can be read and written even when the number of bits of data differs between in case of accessing a built-in memory of an LSI inside the LSI and in case of accessing it from outside the LSI.
