Abstract: PROBLEM TO BE SOLVED: To provide an organic coated steel sheet excellent in corrosion resistance to deteriorated gasoline, weldability, and press moldability, by forming a coating film containing an aqueous urethane resin, whose glass transition temperature represents a specific value, as an essential component on at least one side of a plated steel sheet. SOLUTION: At least one side of a plated steel sheet is made to be covered with an organic coating, wherein a resin, of which main component is an aqueous urethane resin and glass transition temperature is between 100 deg.C and 150 deg.C, is used for the organic coating. Moreover, by using free film whose tensile strength is 400 kg/cm<2> or more and elongation is 5% or more, excellent corrosion resistance and moldability are provided. As for the resin to be used, a urethane resin, which contains bisphenol skeletons and ester skeletons and has carboxyl groups in the structure, is more preferable.

Title: Image processing unit
Inventor: HIRATA KAZUKI
IPC: G06T5/20
Filed: 1994-12-08
Abstract: PURPOSE: To provide an edge emphasis image processing unit in which a parameter is simply adjusted and the relation between an input value and an output value is simply predicted. CONSTITUTION: An image input section 11 acquires digital image data from a received image. A flatness numerical quantity processing section 12 acquires a value resulting from applying numerical quantity processing to a flatness of an image from the digital image data, e.g. a quantity to express a local flatness such as standard deviation of vicinity values. A picture element conversion function generating section 13 generates a function derived from a picture element conversion function for edge emphasis, e.g. a Sigmoid function based on the value applying numerical quantity processing to the flatness of the image. A picture element transforming section 14 transforms the picture element of the digital image data based on the picture element transformation function to decide an output picture element.  An image output section 15 receives an output picture element to provide an output of a processed image whose edge is emphasized.

Title: Simulation system for analog and digital mixture circuit
Inventor: TANABE NORIO
IPC: G06F11/25
Filed: 1990-11-13
Abstract: PURPOSE:To efficiently and inexpensively simulate an analog A and digital D mixture circuit by continuing the logical operation of a digital circuit to control the time synchronization between analog and digital circuits after going back to the event time in the case of difference between an extrapolation forecasted value and an actual analog input signal logical value. CONSTITUTION:An analog input signal 1 and the input signal of an integrator 2 as the extrapolation forecasted value are inputted to the integrator 2 to generate an output signal. A comparator 3 takes the analog input signal 1 and the output of the integrator 2 as the input to compare them with each other and generates the output in accordance with the signal difference. If the extrapolation forecasted value and the actual analog input signal logical value are different, the logical operation of the digital circuit is continued to control the time synchronization between analog and digital circuits after going back to the event time. Thus, efficient simulation circumstances are inexpensively obtained with the A and D mixture circuit where the time constant is widely distributed.
