Title: Manufacture of decorative plate
Inventor: MATSUDA HIROSHI
IPC: B32B33/00
Filed: 1979-11-30
Abstract: PURPOSE: To obtain a gorgeous decorative plate of superior solvent resistance and wear resistance that provides emphastic unevenness by applying recesses of a base board with heating type foaming agent-added ink and by irradiating the ultraviolet- ray setting type clear, applied on the entire surface of the base plate, with ultraviolet rays.  
     CONSTITUTION: Recesses 2 of base plate 1 are applied with heating type foaming agent-added ink 3 and the surface of base plate 1 is coated with an adequate amount of ultraviolet-ray setting type clear 4 including recesses 2. Then while ultraviolet- ray setting type clear 4 is set by irradiating the surface with ultraviolet rays, heating type foaming agent-added clear 4 applied to recesses 2 is foamed by the heat of an ultraviolet-ray irradiation lamp. As a result, because said ink 3 is foamed in an uneven shape, said clear 4 forms uneven shape 6 to have fine sandy uneven surface 5, so that a gorgeous decorative plate of superior solvent resistance and wear resistance with the luster of the clear can be obtained.

Abstract: PURPOSE:To intend the miniaturization of an element and a noize decrease by piling and arranging an occurring portion of an elastic surface wave SAW and an amplification portion upon an laminating layer direction of a piezoelectric body layer and a semiconductor layer. CONSTITUTION:A ZnO piezoelectric body 11 is piled upon a P-type Si 14 through a SiO2 film 13 and a comb-type electrode 12 is attached thereto. A couple of N<+> layers for direct current electrode are embed towards a propagation direction A on the surface of the Si 14. After an AC and a DC are connected to the electrode 12, the Si 14 is earthed. A depletion layer 18 and a inversion layer 19 are caused on the surface of Si 14 by DC power source. When the AC is applied, the SAW occurs on layer 11. On the other hand, when the voltage is applied toward the A direction of the AC electrode 15, free electric charges in layer 19 increase the amplitude of SAW. At this time, the SAW of the reverse direction against A is damped by the DC electric field of the electrode 15. Further, since the electrode 12, and 15a and 15b are piled up in the laminated direction, the device is miniaturized without extending horizontally.

IPC: G09G3/36
Filed: 1988-06-24
Abstract: PURPOSE:To reduce the power consumption by generating a potential difference between mutually different levels by a potential difference generating means and supplying a driving signal to a potential difference selecting means. CONSTITUTION:The power circuit 4 consists of transistors(TR) Tp1 and Tp2 as the potential difference generating means which generates the constant potential difference by being applied with a DC voltage and TRs Tp3 and Tn1 as the potential difference selecting means which extracts a desired-level potential difference selectively from the potential difference by turning on and off said TRs Tp1 and Tp2. Those TRs are paired and connected in parallel to constitute voltage dividing circuits 4a and 4b as a voltage dividing means which divides an applied DC voltage Vdd into different level voltages and leads them out individually. Thus, the driving signal is supplied to the potential difference selecting means and the difference level voltages are extracted selectively from potential differences generated by the potential difference generating means and led out. Consequently, a source voltage of necessary level can be supplied with low power consumption.
