Abstract: PURPOSE: To form the three-dimensional patterns of superior decorative effect provided with bright colors by coating transparent paint on a base material such as wood, metal or other, coating colored paint thereon then passing the material between a relief roll and feed roll while both paints are undried.  
     CONSTITUTION: After undercoating is applied, if necessary, on a base material such as wood, inorganic plate, metal, etc., transparent paint composed of polyester resins or melamine resins and a solvent is coated thereon. Next, colored paint is coated thereon and while both paints are undried, the material is passed between a relief roll and a feed roll in such a manner that the coated surface make contact to the relief roll, whereby undulated patterns are formed, thence the material is dried to allow the paints to set.

Title: Fin line structure
Inventor: ROBAATO DEIRU ARUBIN
IPC: H03D9/00
Filed: 1987-04-16
Abstract: PURPOSE:To simplify the constitution and to improve the matching characteristics of a bias circuit and to improve the universal applicability of this circuit to various other circuits, by providing a distribution capacitance containing a metallized layer to a fin line. CONSTITUTION:The metallized layers 18, 19 and 118 are provided on a surface 21 of a dielectric substrate 14 with a slot 30 and slits 55 and 56 formed respectively. While the metallized layers 42 and 44 are formed on the rear side of the substrate 14 against slits 55 and 56 and serve as the distribution capacitances that short-circuit the radio frequency signals. Here the layer 118 is floated up from a waveguide 16 in term of a direct current since both slits 55 and 66 receive no DC short circuits from said capacitances. Thus the bias is facilitated to a coupling element 124 consisting of a semiconductor element, a resistance and a capacitor. Furthermore the conversion efficiency is secured for an impedance matching/detecting device when the element 124 is mounted just by setting the line length of the slot 30 at about l/4 transmission wavelength. Thus the wide band characteristics can be expected. This fin line structure is also applied to a modulator, an amplifier, a multiplier, etc.

Title: Infrared ray detector
Inventor: MAEJIMA YUKIHIKO
IPC: H01L31/10
Filed: 1990-04-10
Abstract: PURPOSE:To enable an infrared ray detector to be improved in high speed responsibility by a method wherein N-type and P-type layers which are smaller than a first semiconductor layer in carrier concentration and thickness are alternately laminated in layers on the N-type or the P-type first semiconductor layer narrow in forbidden band width, and a second semiconductor layer whose conductivity type is opposite to that of the first semiconductor layer is formed thereon. CONSTITUTION:A depletion layer is formed at the part of a P-type thin layer 6 in contact with an N-type layer 7 even if a bias voltage is not applied, where the layer 6 is smaller than a P-type layer 2 in carrier concentration and the layer 7 is smaller than an N-type layer. 3 in carrier concentration, depletion layers are not linked together, and P-N junctions are connected in series in 10 stages. On the other hand, a P-side electrode 4 of this detector is grounded, and when a voltage (reverse bias) of -1V or so is applied onto an N-side electrode, a depletion layer is made to expand in each of the P-N junctions, the depletion layers are linked together, and a part where the thin P-type layer 6 and the N-type layer 7 are laminated is totally depleted. Therefore, an infrared detector of this design is smaller than a conventional one in capacity of a depletion layer, so that it can be improved in high speed responsibility.
