Title: Simulation method for analog digital mixture circuit
Inventor: YOSHINO TETSUO
IPC: H03K19/00
Filed: 1990-07-17
Abstract: PURPOSE:To shorten the simulation time of an analog part by converting the transfer function of the analog circuit part described with an S function to a Z function to synthesize a corresponding digital circuit network and coupling it to the other digital circuits to obtain the input of logic simulation. CONSTITUTION:The transfer function described with the S function of the analog part is converted to the Z function based on the sampling period of a clock generator 33 which has a period corresponding to the simulation precision, and the digital circuit network corresponding to this converted Z function is synthesized by adders 15 to 22, multipliers 23 and 24, and a delay register 25 and is coupled to the other digital parts to obtain the input of a logic simulator. Thus, a high-speed logic simulation technique like even driven logic simulation is effectively used to simulate a circuit where analog and digital parts exist together, and the execution time like the simulation time of the analog part is shortened.

Title: Alloy plating of zinc and titanium and material and product subjected to diffusion alloy constituting treatment to said plating
Inventor: SATO SHINZO
IPC: C25D3/56
Filed: 1984-09-11
Abstract: PURPOSE:To provide corrosion resistant alloy plating of Zn and Ti by which plating time can be reduced and a material and product which is formed by subjecting the plating to a diffusion alloy constituting treatment and has extremely high corrosion resistance. CONSTITUTION:The Zn-Ti alloy plating consists of 99.5-0.5% Zn and 0.5-99.5% Ti in the weight ratio of Zn and Ti. The known Ti plating entails long plating time and is far from practicability and therefore said plating is brought to a practicable level by alloying the same with Zn. The content of Ti in Zn can be freely changed by controlling current and time and the shorter plating time is required as the content of Zn is higher. However, the corrosion resistance is higher as the content of Ti is higher. The electrolytic Ti produced by electrolytic deposition has powerful diffusion energy at a low temp. and therefore when such Ti is heated without oxidation to about 200 deg.C, the Ti infiltrates and diffuses for about 30 minutes into the plated base material. Since the Zn is in the mid-way of infiltration, the Zn-Ti alloy is diffused. The base material having the improved hardness, tensile strength, elasticity, etc. in addition to the remarkably improved corrosion resistance is thus obtd.

Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To prevent a Mach band from being generated, even when two images with lightness changes are overlapped and synthesized by generating the images so as to continue the primary differentiation of lightness and overlapping the generated plural images. SOLUTION: Images to be overlapped and composited are generated so as to continue the primary differentiation in changes of lightness. Figure (a) shows the change in the lightness of the images generated like this. Concerning such an image, primary differentiation is always continued except for the center as shown in the figure (a). Thus, when the images are composited so as to continue the primary differentiation of lightness at all times, the primary differentiation in the change of lightness is continued. Figure (b) shown this. In this figure (b), it is shown the lightness is changed smoothly, even at points A' and B' to overlap the images and the primary differentiation is continuous. Thus, no Mach band is generated.
