Filed: 1992-01-28
Abstract: PURPOSE:To improve the color reproducibility and the picture quality with respect to an object color by employing the fuzzy deduction, deducting the adaptability of plural control variables to each membership function based on the adaptability of plural state variables to each membership function and calculating the correction value of each control variable therefrom. CONSTITUTION:A temperature, a humidity and a total carried paper number based on a temperature sensor 300, a humidity sensor 302 and a counter 304 are outputted to a CPU 500 via A/D converters 301,303 and an I/O circuit 305, and a current temperature, a deviation in the humidity, a deviation in the total carried paper number, a temperature gradient and a humidity gradient with respect to the standard temperature and humidity are calculated therein. Then the degree of each control variable relating to a fuzzy set is calculated based on the degree of a state variable relating to the fuzzy set according to each fuzzy rule and the highest possible control variable is calculated by obtaining its gravity center. Thus, color correction is implemented in response to the environment or the total use of the device at that point of time in this way.

Abstract: PURPOSE: To prevent the flow of Au-Si eutectic crystal to a tab lead by forming a stopper for preventing the flow of the eutectic crystal between the tab and the earth bond of the tab lead.  
     CONSTITUTION: A grooved recess 17 is formed on a part of the surface between a tab 12 and the earth bond 14a of a tab lead, and is formed as a stopper for preventing the flow of an Au-Si eutectic crystal 19. According to this structure, even if the crystal 19 produced between the front surface of the tab 12 and the back surface of a pellet 10 at the time of bonding the pellet 10 is molten on the surface of the tab 12 to flow on the lead 14, the recess 17 can stop flowing of the crystal 19 to the bonded part 14a. Accordingly, in the step of connecting the wire 16 for the earth bond to the bonded part 14a of the lead 14, the eutectic crystal 19 does not flow to the bonded part 14a, and accordingly the bonding of the wire 16 can be effectively performed.

Title: Coating method
Inventor: SAKAKIBARA TAKAO
IPC: B05D1/36
Filed: 1980-02-07
Abstract: PURPOSE: To obtain a continuous and uniform coating film through only one time of baking by specifying the moisture content of a water-base coating applied on a metallic substrate having an intricate shape then applying electrodeposition coating.  
     CONSTITUTION: A water-base coating is applied on a substrate made of conductive metal of bag shape or an intricate shape having slit parts etc. Thence, this coating film is left standing to regulat the moisture content in the coating film to about 2W15wt%. The moisture content is determined by the measurement of the substrate weights before and after drying. In case when the moisture content is lower than that of said range, the conductivity of the coating film lowers and electric resistance increases; hence, the formation of the electrodeposition coating film of the next process is difficult on the thin film where coating is difficult such as the inside part of the bag shaped part etc. of the substrate. If, on the contrary, the moisture content is higher than said range, the water-base coating elutes and the electrodeposition coating film is formed on the water-base thick film part as well of the easy-to-coat areas because of low electric resistance, at the time when the substrate is immersed in an electrodeposition coating bath in the next process, and this produces the waste of the coating. The substrate controlled of the moisture content and electrodeposition coated is baked and dried.

Title: Magnetic recording medium
Inventor: YAMAGISHI MINORU
IPC: G11B5/706
Filed: 1989-01-24
Abstract: PURPOSE:To reduce the noise intensity without changing reproduction output and to improve the signal to noise ratio by specifying the coercive force squareness ratio of the magnetic recording medium. CONSTITUTION:The coercive force squareness ratio (S) is specified to the range from 0.62 to 0.89. The relation between the noise power (Nw) and the squareness ratio of the medium is that Nw decreases with decrease of S. S can be reduced by decreasing the temp. of the substrate in the production process of the medium, while too small S is not preferable since the resolution of the medium decreases with S. Therefore, the temp. of the substrate in the process of manufacturing the medium is determined so as to obtain S in the range from 0.62 to 0.89. Thus, the obtd. medium has low Nw and enhanced S/N.
