Abstract: The inventive vessel, e.g. crucible, made of a refractory inorganic material such as boron nitride has a multi-layered wall structure which is an integral alternate lamination of layers of higher density and layers of lower density. Such a multi-layered structure can be formed by the procedure of pyrolytic chemical vapor deposition in the course of which the concentration of the gaseous reactants, e.g. boron trichloride and ammonia, in the atmosphere is changed, i.e. increased or decreased, under control so that the resultant deposited boron nitride layer has different densities in the portions deposited before and after the concentration change. By virtue of the multi-layered wall structure, the vessel has outstandingly improved resistance against thermal shock and can withstand prolonged use or many times of repeated use at high temperatures without breaking or crack formation.

Abstract: The invention provides an electrothermal hot-melt type thermal transfer ink ribbon having a multi-layered structure used in thermal printers having a multi-stylus electrode head. Different from conventional ink ribbons of such a type composed of an electroconductive base film as a resistive layer, a vapor-deposited aluminum layer to serve as an electric pass to a return electrode and a layer of a hot-melt ink, the inventive ink ribbon has an additional layer as a heat barrier between the aluminum layer and the hot-melt ink layer so that the heat generated in the resistive base film and reaching the ink layer is radially diffused to produce a remarkable temperature gradient within the dot decreasing from the center to the periphery thus to provide a possibility of gradation control of the optical density of the printed dots by means of the voltage adjustment.

Abstract: A covering member of keyboard prepared by separately fixing the push button elements to a base plate instead of integral molding is disclosed in which the plate has openings arranged conforming to the pattern of the fixed contact points on the circuit board. Fixing is carried out by using a silicone rubber-based adhesive or a pressure-sensitive adhesive optionally with the aid of tailing of protrusions on the base plate into the cavity of the base of the push button elements. A method of using unit bodies carrying push button elements is alternatively used. A base plate having openings arranged in the pattern corresponding to the fixed contact points is also disclosed for use in fixing the push button elements.

Abstract: A multilayer printed circuit board which reliably and economically marries conventional copper clad printed circuit board technology with polymeric conductors and insulators. Reliability is enhanced by forming all solder pads of copper, providing conductive tails on solder pads which are to be connected by polymeric inks, and ultimately forming a solder resist over all but the solder pads. As a result, polymer inks can be applied to both sides of the board, and the completed board can be subject to conventional solder dipping or wave soldering operations. According to one feature of the invention, a thin dielectric layer can be applied as intermediate to planar conductive layers which form a power plane having built-in distributed capacitance for decoupling.
