摘要:
A thermoplastic resin foam which has both high reflectance and superior shape-retention properties, suitable for use in backlights and illumination boxes for illumination signboards, lighting fixtures, displays and the like. The thermoplastic resin foam is manufactured by a manufacturing method including a procedure for holding a resin sheet composed of thermoplastic resin (A) and thermoplastic resin (B), which has a functional group having an affinyty with thermoplastic resin (A), within a pressurized inert gas atmosphere to enable the resin sheet to contain inert gas, and a procedure for foaming by heating the resin sheet containing inert gas at a temperature higher than the softening temperature of thermoplastic resin, under normal pressure.

A thermoplastic resin sheet which has both a high reflectance ratio and excellent shape-holding property suitable for backlights and illumination boxes for use in illumination signboards, illumination fixtures and displays and illumination boxes. The thermoplastic resin foam is manufactured by a manufacturing method including a process for containing inert gas by holding thermoplastic resin sheet containing metallic oxide in a pressurized inert gas atmosphere and a process for heating the thermoplastic resin sheet in which the inert gas is contained at a temperature higher than the softening temperature of the thermoplastic resin, under normal pressure, and foaming the resin.

摘要:
The disclosure relates to a photoconductive ignition system including a photoconductor configured to contact an oxidant-fuel gas mixture, and a light source providing irradiating light to a surface of the photoconductor. The photoconductor absorbs at least some of the light from the light source, which causes a variation in electrical potential at the surface of the photoconductor, thereby igniting the oxidant-fuel gas mixture. The disclosure further relates to a method of activating an oxidant-fuel gas mixture by exposing a photoconductor surface to the gas mixture and irradiating the surface with a light source emitting light at a wavelength corresponding to an energy level greater than a band gap energy level of the photoconductor, thereby activating the gas mixture in a combustion reaction.

摘要:
An automatic sewing machine includes a sewing machine mechanism having a seam forming mechanism and a fabric feed mechanism. A detector member senses the position of each free side edge of two layers of fabric to be fed to the seam forming mechanism and generates signals. A pair of manipulators capable of engaging each layer of fabric individually move such each layer of fabric to a predetermined position in response to signals from the detector members. The free side edges of layers of fabric are automatically stitched together by a predetermined distance along the free side edges with the edges maintained in alignment with each other.
