Title: Plastic plated article and its production
Inventor: YOSHIYAMA KIICHI
IPC: C08J7/06
Filed: 1993-01-19
Abstract: PURPOSE:To easily pretreat the surface of a molding to be plated in a short time by integrally forming a plastic molding with a base which is not oxidized by an etchant and a part to be plated which is oxidized. CONSTITUTION:A plastic molding 1 is integrally formed from a PC resin base 2 and an ABS resin part 3 to be plated. The molding 1 is cleaned, degreased and then dipped in an etchant such as a chromium sulfate soln. to etch the part 3. The molding 1 is placed in an aq. soln. of palladium chloride and tin chloride to deposit palladium on the part 3, and then the part 3 is electroless plated with nickel to form a nickel coating film. The nickel coating film is finally electroless-plated with nickel and chromium to form a desired metallic coating film 4. As a result, the region other than the part 3 need not be masked, and the cost of the plated plastic article is remarkably reduced.

Title: Optical touch switch
Inventor: YABUUCHI MASAMI
IPC: G06F3/048
Filed: 1987-02-03
Abstract: PURPOSE:To improve the operability of an optical touch switch at the time of key input by invalidating the input to one or more blank areas and at the same time validating the key input of a single specific switch display area when the simultaneous switch operations are given to those display and blank areas. CONSTITUTION:A CPU 20 compares the operation input coordinates given from photoelectric sensors 2 with the picture element coordinates of the switch display areas 11-14 and blank areas 15-17. Based on these comparison results, the CPU 20 invalidates the switch input when plural switch display areas are simultaneously operated and validates the switch input of only the switch display areas in case both switch display and blank areas are operated at one time. Therefore the original key input operation are never invalidated even though the undesired contacts of foreign matters like, fingers, the clothes, etc., are given to the areas 15-17. Thus the oversensitiveness of the key input inhibiting control is avoided and the operability is improved at the time of key input.

Filed: 1984-02-10
Abstract: PURPOSE:To improve the efficiency of vapor deposition and to reduce the production cost by setting at least one or more units of the evaporation source of a resistance heating system or a direct heating system in the evaporating direction of a material evaporated from another evaporation source. CONSTITUTION:The 1st evaporation source 15 is heated to melt and evaporate the 1st evaporation matter 16. A part of the evaporated matter 16 is attached directly and obliquely to a substrate 12. Thus a metallic layer, etc. are formed on the surface of the substrate 12. Another part of the evaporated matter 16 is attached to the outer circumference of the 2nd evaporation source 17 and then evaporated immediately to be attached mostly to the substrate 12 since the source 17 is heated by a resistance heating or direct heating process. The 2nd evaporation matter 18 evaporated from the source 17 is attached on the surface of the matter 16. Thus a part of the evaporation matter which is so far attached unnecessarily to the peripheral devices and not to the substrate 12 is attached to the source 17 and then evaporated again by the heat of the source 17 to be attached to the substrate 12. This improves the efficiency of evaporation and reduces the production cost.
