Filed: 1987-10-23
Abstract: PURPOSE:To enhance conversion efficiency by a method wherein a single metal layer, p-type CdS or a compound semiconductor layer containing it and n-type CdTe or a compound semiconductor layer containing it are laminated on a highly corrosion-resistant substrate. CONSTITUTION:A single metal layer 2 is formed on a substrate 1; after that, p-type CdS or a compound semiconductor layer 3 containing it is formed; n-type CdTe or a compound semiconductor layer 4 containing it is formed on the layer 3 by means of an electrochemical reaction. Accordingly, it is not required to extract a lead wire directly from the high alloy or low alloy substrate 1; it is possible to prevent a current density value from being lowered due to a nonmetallic inclusion in the substrate 1 and in prevent various elements in the substrate 1 from being diffused while they are sintered into the p-type CdS. In addition, because the electrochemical reaction is used for the n-type CdTe, no void is produced at an interface between both formed layers. In addition, S (Te) is hardly diffused into the n-type CdTe or the compound semiconductor layer containing it (the p-type CdS or the compound semiconductor layer containing it) near the interface. By this setup, it is possible to enhance conversion efficiency.

Filed: 1986-11-12
Abstract: PURPOSE:To obtain a shrink film for a label, which possesses shrink characteris tics, heat-sealing characteristics, hot water resistance and solvent resistance, by allowing a film to possess a specific birefringent index, shrinkage factor and film haze. CONSTITUTION:A birefringent index of a polyester shrink film is 0.050-0.150 and shrinkage factor in 5 minutes within an air oven of 100 deg.C is 40% or higher in one direction, and 15% or lower in the other direction. A film haze after the film has been dipped into hot water of 85 deg.C under tension and fixation is 20% or lower. Hot water resistance is improved drastically, and whitening or wavy creases or slack of the said film does not generate at all at the time of sterilization treatment, in the case of a film of the birefringent index of 0.05 or higher. The film of the birefringent index of less than 0.050 is inferior in solvent resistance and in the case where the same exceeds 0.150, a void is generated within the film and transparency is deteriorated. In the case where unidirectional shrinkage factor is not at least 40% and the filmis used for a label, the film does not adhere close to a bottle, or it does not shrink evenly. When the other shrinkage factor exceeds 15%, a shear in design is generated.

IPC: G06K9/20
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To simplify the operation procedure for recognizing characters. SOLUTION: An image containing character is inputted from an image input means 6 to a character recognizing device and displayed on an image display means 11. A user inputs an instruction from an instructing means 13 while viewing the image. Corresponding to the inputted instruction, a central arithmetic unit 2 designates the area to recognize the character. Besides, according to this instruction, recognition conditions are selected for deciding which recognition dictionary in a dictionary memory 17 is to be used for recognizing the character. The central arithmetic unit 2 extracts the outline rectangle of the character out of the designated area and finds its mesh feature.  A character recognizing means 16 calculates the degree of similarity by comparing the mesh feature of the outline rectangle with the mesh feature of a character stored in the recognition dictionary decided on the recognition conditions and recognizes the character having the highest degree of similarity as the character of the relevant outline rectangle.
