Title: Method of etching multicomponent solid material
Inventor: KANEKO KAZU
IPC: H01L21/208
Filed: 1995-02-01
Abstract: PURPOSE: To etch a multi-component solid material with an improved etching speed and to obtain a smooth etched surface by bringing the other surface (upper surface) of the solvent, which contacts with the surface of the multi-component solid material, into contact with an atmosphere in which a component constituting the material dissolved in the solvent can volatilize.  
     CONSTITUTION: A pattern mask layer 3 made of SiO 2  is provided on the surface of the objective semiconductor layer 2 to be etched, e.g. GaN, and the semiconductor layer 2 with the pattern mask layer is placed in a chamber. The atmosphere in the chamber is displaced with an atmosphere enriched in an easily reactive gas (e.g. atmosphere displaced with H 2 ) with N of semiconductor layer 3 or with Ar gas atmosphere having a low N 2  partial pressure. A pipe 5 equipped with means for heating is placed on the semiconductor layer to be etched and a solvent 4 is filled in the pipe so that the surface (b) of the solvent contacts with the semiconductor layer 2 and the mask layer 3, and upper surface (t) of the solvent contacts with the atmosphere in the chamber, Ga and N contained in the semiconductor layer 2, which contacts with the surface (b) of the solvent 4, dissolve in the solvent 4 in the direction indicated by α, and N volatilizes from the surface (t) in the direction indicated by β into the chamber. The volatilized N reacts with H 2  to form NH 4  or diffuses into the atmosphere having the reduced N 2  partial pressure.

Abstract: PURPOSE:To form a three-dimensional image having excellent durability and decorativeness on the surface of a substrate and integrally assimilate a printed pattern with a picture material placed thereon, by foaming a foamable coating material on a printed part of the substrate, and adhering a film thereto by sucking and heating from the back side of the substrate through vent holes. CONSTITUTION:A multiplicity of vent holes 3 are provided at appropriate positions of a substrate 1 in the form of, for example, a plurality of chain lines. A foamable UV-curable coating material is applied to a decoratively printed pattern 4, and is foamed to have an appropriately raised surface. A film 6 is adhered thereto by heating while sucking from the back side 7 through the vent holes 3, whereby the film 6 is firmly adhered to the surface 2 of the substrate 1. The firm adhesion brings the film 6 onto uniform close contact with the pattern 4 and a picture material 5, so that the raised conditions of the pattern 4 and the picture material 5 can be developed with fidelity. Therefore, the pattern 4 and the picture material 5 are seen in an integrally assimilated condition, and when the picture material 5 is pressed flowers, the pattern 4 itself is seen similar to the pressed flowers even if it is a printed image.

Title: Circuit for driving (electroluminescent) element
Inventor: MOCHIZUKI SHIGEHIRO
IPC: H05B44/00
Filed: 1994-02-14
Abstract: PURPOSE:To prevent excessive rise of applied voltage due to initial property change of an EL element and prolong the life of the element by putting a capacitor in parallel to the EL element in the output terminals of an EL element driving circuit. CONSTITUTION:A capacitor 5 with capacity C1 is connected between output terminals P, P of an EL element driving circuit 1 in the way the capacitor is connected in parallel to an EL element 10. Consequently, high frequency electric power is applied to the capacity C1 and the capacity component C2 and resistance component R of the EL element 10. The driving circuit supplies voltage determined by calculation of Vc=QE wherein Q value is determined by the compounded value (C1+C2) and resistance component R, that is Q=1/R (C1+CC2). In the case the capacity C1 is set to be relatively large, even if the C2 alters as an initial property of the EL element 10, the alteration of the compounded value (C1+C2) can be lowered. The alteration of the voltage to be applied is thus lowered. In the case the capacity C2 is set to be large, since the consumption electric power becomes also high, the capacity value at the minimum limit which does not exceed the maximum rated value of the EL element 10 is set for the capacity C2.

CONSTITUTION:On one face of one porous humidity-sensitive element 2, two electrodes are provided, and an electrode is provided over the whole surface of the other side. More than two thermistors 3 and 4, a fixed resistor 6 and an element 2 are directly fixed to an alumina substrate with a conductive pattern 5 and a bonding material 7 so as to constitute a circuit. Thus, linearity of output voltage against humidity in the rage from 30% RH to 95% RH is improved. Next, as one of the electrode and the whole-surface electrode, and the other electrode and the whole-surface electrode of the element 2 work as two, the size can be reduced. Also, as the element 2 is not in touch with the substrate and the thermistors 3 and 4 other than the contact of the two electrodes, bleeding is eliminated at impregnation of a humidity-sensitive material, dispersion in humidity characteristic is reduced, characteristics in mass production are stabled and responsiveness of a humidity sensor can be improved.
