Abstract: ABSTRACT OF THE DISCLOSURE       First, a decorative sheet is produced by forming in sequence on a base paper such as titanium paper an ordinary printed layer and a heat-foamable printed layer, respectively with desired patterns.  The decora-tive sheet is then impregnated with a thermosetting resin liquid and dried.  The dried impregnated decora-tive sheet is superposed on a substrate such as a core sheet, and the resulting laminated structure is sand-wiched between a pair of heating plates and heated and pressed whereby a thermoset integral structure with the pattern of the foamable printed layer foamed is produced.          The entire surface of the integral structure is coated with a solvent to swell the foamed pattern layer and then rubbed to remove the swollen foamed pattern layer and form concavities thereat.  The resulting thermoset resin decorative sheet or plate is provided with deep distinct concavities coincident with the pattern of the heat-foamable printed layer as well as a good surface luster.

Abstract: Abstract of the Disclosure:     The invention relates to a method of and an apparatus for measuring surface temperature of especially moving objects, advantageously measuring the temperature of fibrous products, and particularly of wires during production.  The essence of the method lies in that two concentric shells not being contiguous with either the object to be measured or with one another are fitted to the object to be measured, temperature is sensed in the two end locations and in the central region of the inner shell and in the central region of the outer shell, these values are brought to be equal to the value measured in the central region of the inner shell by dissipation or by heat transfer (heating), then temperature is measured in the central region of the inner shell.  The essence of the apparatus lies in that it comprises two concentric shells separated from one another, an inner sensing and an outer compensating shell, being provided with heated surfaces, and dissipating elements, respectively.  The method and the apparatus according to the invention are suitable for measuring surface temperature of moving elements, par-ticularly of wires, fibres, strips moving at a speed of 0 to 65 m/s, irrespective of surface quality, material, or relatively low temperature ranges, where temperature radiation is hard to measure.

Abstract: ABSTRACT OF THE DISCLOSURE  A method for making a diffraction grating utiliz-ing a laser source, a beam splitter to split the light from the laser source into two light fluxes, a collimator to convert each light flux into a light flux which is parallel and enlarged in diameter, a mirror to irradiate each light flux on a substrate coated with a photoresist, and a photomask on the photoresist.  The use of an inter-mediate mask and focusing lens  enables the formation of a diffraction grating within a limited area.  A blazed diffraction grating may be formed by splitting a laser beam into two beams having an increased beam radius, and irradiating a light-sensitive material with the resulting two beams to form an interference fringe.  This method is characterized in that in a first exposure the two beams are incident on the light sensitive material through air to form an interference fringe having a clearance width of d, and in a second exposure, the two beams are irrad-iated on the light sensitive material through a symmetri-cal transparent member having an isosceles triangular cross section in such a manner that the origin coincides to form an interference fringe having a clearance width of d/2, and furthermore, in that the ratio of the first exposure energy to the second exposure energy is made equal to the ratio of the first term to the second term of a Fourier series obtained by expanding the periodical function of the waveform of the blazed diffraction grating.     An optical branching filter element comprised of a sub-strate having a wave guide thereon of a material capable of reversibly changing its refractive index may have a diffraction grating formed in the waveguide by either of the disclosed methods.  The grating may be erased by the selective application of infrared light, electric current or heat.

Abstract: Abstract of the Disclosure A digitizing system includes a first plurality of spaced parallel grid conductors and a second plurality of spaced parallel grid conductors orthogonal to the first plurality of spaced parallel grid conductors.  The location of a movable coil arranged on a pen or cursor is determined for each plurality of grid conductors coarsely by sampling the voltage induced in one of the grid conductors from a signal applied to the coil to determine whether the coil is above or below this grid conductor.          Through careful selection, a very few grid conductors can be sampled to quickly locate the two grid conductors immediately adjacent to the center of the driven coil. The ratio of the voltages present on these two grid conductors is matched against a list of known ratios representing various positions between the two grid conductors.

The inclined surfaces minimize any effect the reflected sound waves may have on the spreading rate of the jet from the nozzle and thus improve the sensitivity of the apparatus.

Abstract: ABSTRACT An ear plug (40) includes an elongate body with a rounded tip por-tion and of an elastic material enveloped by a deep-drawn sheath (41) of thin flexible plastics film material.  Rearwardly the plug preferably has a neck portion from which the sheath projects in the form of a stiffer collar or flange.  Production of the ear plug includes deep-drawing a thermoplastic film or foil into a sheath with desired thickness distribution  and filling the sheath with elastic material (53).  Filling may take place simultaneously with deep-drawing, the body of elastic material constituting a die for deep-drawing in a forming hold (45),  or after the deep-drawing.  In the latter case, an elastic die body is used to advantage  the shape of which generally corres-ponds to that of the finished plug,  for deep-drawing in a forming hold suited to the die body.
