Title: Laser oscillator
Inventor: NAGASAWA YASUYUKI
IPC: H01S3/109
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent harmonic light from entering a laser medium and to stabilize the oscillation of a laser beam by performing coating to a nonlinear crystal so that light with a fundamental wave wavelength can be transmitted and light with a harmonic wavelength can be reflected, and at the same time performing coating to an output mirror so that the light with a fundamental wave wavelength can be totally reflected and light with a harmonic wavelength can be transmitted. SOLUTION: Coating 6 for transmitting light λ1 with a fundamental wave wavelength and reflecting light λ2 with a harmonic wavelength is made to the fundamental wave light incidence surface of a nonlinear crystal 5. Then, coating 7 for totally reflecting fundamental wave light and the light λ2 with a harmonic wavelength is made to an output mirror 4. The light λ2 with a harmonic wavelength being generated in this manner is propagated only in the direction of an output mirror 4, thus preventing light with harmonic from entering a laser medium 2. Also, the output mirror 4 emits only the light λ2 with a harmonic wavelength, so that no fundamental wave λ1 enters a nonlinear crystal 8.  As a result, a laser oscillates stably and the light λ1 with a fundamental wave wavelength is not propagated to the outside of a resonator 12, thus eliminating the need for a dichroic mirror and a damper and easily miniaturizing the laser device.

Title: Smooth shading of object on display device
Inventor: BILODEAU WILLIAM D
IPC: G06T15/04
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To smoothly shade the images which are produced by a computer, by demarcating a double tertiary patch to surround an area in a display space and also demarking a color inclination. SOLUTION: A double tertiary patch surrounding an area in a display space is defined, and the colors are selected and related to four corner parts of the double tertiary patch. Then, a unit square is defined in a parameter space in relation to the double tertiary patch. The unit square is mapped to the double tertiary patch so as to map every point set in the unit square to at least a point set in the tertiary patch. In such cases, the colors of all points set in the unit square serve as the double primary interpolations of four corner part colors related to four corner parts of the double tertiary patch. Thereafter, a user defines a control point to the double tertiary patch. The color of the area is selected via the operation of the control point related to the double tertiary patch in order to generate the desired shading.

Filed: 1993-04-14
Abstract: PURPOSE:To enable a pinhole type defect on a lead type object to be extracted by drawing a frame of maximum or minimum luminance opposite to the luminance value of the object on a binarized image on a screen, and numbering the picture elements of the object in a descending order. CONSTITUTION:In processing the image of a lead type object 1, a frame of maximum or minimum luminance opposite to the luminance value of the object 1 is first drawn on a binarized image on a screen, and the picture elements of the object 1 are numbered in a descending order. Then, a section having the largest number of picture elements is excluded, thereby extracting a pinhole type defect 2 existing on the object 1. Regarding the extracted defect 2, judgement is made about acceptability on the basis of a ratio of the maximum diameter thereof on the object 1 to the breadth of the object 1. In other words, the center of gravity of the defect 2 is calculated and, then, the continuos length of black and white picture elements (run length) at every constant angle is obtained in a radial direction about the obtained center of gravity. Types of run length near the center of gravity of the defect 2 are thus compared with each other. Then, nonconformity is judged on the basis of a ratio of the breadth of the object 1 to the diameter of the defect 2 obtained via arithmetic operation.

IPC: H01Q19/17
Filed: 1994-04-25
Abstract: PURPOSE:To reduce the side lobes for a multibeam antenna which applies a reflector system to continuously cover the service areas by plural spot beams. CONSTITUTION:A radiation beam consists of seven central primary radiator groups including a primary radiator 2a and six primary radiators 2b-2g which are circumscribed to the radiator 2a and 12 primary radiators 2h-2s which are circumscribed to the central primary radiator groups among those perimary radiators which are arrayed in a cellular shape at the focal point of a rotary papraboloidal reflector.

Thus the side lobes are totally eliminated to the radiation beams radiated from those central primary radiator groups.

Abstract: PURPOSE: To prevent the slip and the scratch flaw, by operating the winding length around the mandrel, and by switching over the operation of the mandrel from the speed control to the tension control when the winding length attains to the specified value.  
     CONSTITUTION: If the strip 1 arrives at the unit roll UR3, a friction resistance is generated between the unit roll UR3 and the strip 1, and the load of the motor 7 increases. This load current is detected by the current transformer C.T, the signal is sent to the load relay L.R; if the load current is larger than the set value, the relay L.R is put ON and the normally-closed junction S4 is closed. Hereby, the output of the speed detector PLG2 is given to the integral amplifier 8, which then operates the winding length of the strip 1. The output of the integral amplifier 8 is given to the comparator 9, and is compared with the reference length; when the winding length becomes larger than the reference length, the completion of the winding is judged, and the comparator 9 activates the relay Ry. Then, the normally-open junctions S1, S3, are closed, the normally-closed junction S2 is opened, the wrapper rolls 5AW5C are released, and at the same time, the control of the mandrel driving motor 4 is switched over from the voltage control to the tension control.
