Abstract: PURPOSE:To facilitate setting of a circular arc in the form of a corner by designating the radius of the circular arc and if it is inserted to the inside of a corner or the outside so as to insert the circular arc of the radius automatically in setting the form of the corner. CONSTITUTION:An R key meaning rounding at a corner part Ci of a form PRF is selected, then a radius ri for this rounding is inputted, and it is selected if a circular arc (circular arc of an inner R) is inserted inscribing adjacent form elements ESi, ESi+1, or a circular arc (circular arc of an outer R) is inserted having center coordinates of the intersection of the adjacent form elements ESi, ESi+1 on the outside of the corner. If a circular arc of inner R is selected, a circular arc of a rounding radius ri is inserted inscribing the form elements ESi, ESi+1 adjacent to the corner part Ci, while if a circular arc of an outer R is selected, a circular arc of a rounding radius ri is inserted having center coordinates of the intersection of the form elements ESi, ESi+1 adjacent to the corner part Ci on the outer side of the corner, thereby the form of a corner is specified.

Title: Apparatus for analyzing defect in magneto-optical recording medium
Inventor: AKIHIRO MAKOTO
IPC: G01N21/93
Filed: 1987-12-28
Abstract: PURPOSE:To make it possible to detect and evaluate minute defects in a recording medium and their growing steps and to make it possible to separate the polarizing light type defect and the non-polarizing light type defect and to detect and analyze the defects, by providing a condensing optical system, optical sensors, an operating circuit and the like. CONSTITUTION:When a recording medium D is relatively moved with respect to a condensing optical system 2, reflected light from the recording medium D is divided into two polarized light components having the different polarization angles through the optical system 2. The light beams are inputted into optical sensors 6 and 7 and transduced into electric signals. The electric signals are operated in an operating circuit 8. The voltages, which depend on the polarization angle and the intensity of the reflected light, are selectively outputted. Low frequency noises are removed from the voltages in a high frequency filter 9. The voltages, which exceed a reference voltage, are outputted from a differential amplifier 10 and counted 11 based on the lengths of the pulses. In this way, the minute defects and the growing steps of the medium D can be detected and evaluated. The deflecting light type and non-light type defects can be separately detected and analyzed.

Abstract: PURPOSE:To improve the contrast ratio and color shading and to obtain a picture with high quality by arranging a tint member between a face plate of a projection CRT and a rear face of a projection lens provided in front of the face plate. CONSTITUTION:A tint member 17 is arranged between a face plate 12 of a projection CRT 11 and a rear face of a projection lens 13 in front of the plate 12. Thus, a reflected light in the lens barrel and on the surface of the projection lens is largely absorbed while being passed through the tint member reciprocatingly, the reflected light reaching the screen is decreased to improve the contrast ratio considerably. Thus, a picture with high quality is obtained and when a tint member whose light transmissivity is partially different is in use as the tint member, the color shading generated due to different projection main axis is improved.

Title: Method for locating faulty section of transmission line
Inventor: HORIBATA HIROSHI
IPC: G01R31/08
Filed: 1992-11-18
Abstract: PURPOSE:To reduce the number of current detecting sensors (CT) by estimating the current and phase information at a steel tower to which no CT is installed from the information of an installed CT. CONSTITUTION:By installing CTs to, for example, half of steel towers, the neurons of an input layer and output layer are made to correspond to the current and phase information at a required steel tower by using a neural network composed of the input layer, an intermediate layer, and the output layer. The neural network is built so that, when the current and phase information are given to the input layer in case a fault occurs, the values of the current and phase appear as they are in the output layer. While the current and phase information are obtained from a limited number of steel towers when a fault occurs, the obtained information are inputted to the input layer of the neural network as they are and the mean values, etc., of adjacent values are inputted as unknown current and phase information. Of the calculated results of the neural network, the unknown current and phase information are returned to the input layer and known information are again calculated by inputting the same values as the preceding values. By repeating similar calculation, the current and phase information at a steel tower to be located are obtained.

Filed: 1992-11-19
Abstract: PURPOSE:To obtain an excellent print without a fringe even if printing speed is increased and the design precision of a machine is made rough by electrostatically separating toner stuck to a nonimage part on an electrostatic latent image carrier after development. CONSTITUTION:The layer of one-component toner 4 on a toner carrier 1 is brought into contact with the electrostatic latent image carrier 5, to actualize an electrostatic latent image 6. As a mechanism removing the toner stuck to a fringe part generated on the circumference of the image part of the electrostatic latent image 6, a conductive roller is provided on the downstream side of a developing unit and the upstream side of an electrostatic transfer mechanism. A voltage having the polarity reverse to that of the toner stuck to the fringe part is impressed to this roller and it comes into contact with the electrostatic latent image carrier 5 after being developed or approaches it. The toner stuck to the image part and the toner stuck to the fringe part have opposite polarities each other. Therefore, electrostatic attracting force acts on the toner on the fringe part and repulsive force acts on the toner on the image part. Thus, the toner on the fringe part is selectively removed.
