Title: Secondary higher harmonics generation device
IPC: G02F1/37
Filed: 1992-03-16
Abstract: PURPOSE:To obtain a spot of secondary higher harmonics light or parallel luminous flux on an optical axis which has maximum intensity and is in focus by stabilizing the oscillation wavelength of a fundamental wave and thus stabilizing the angle of Cherenkov radiation light. CONSTITUTION:A semiconductor laser(LD) 100 which has an incidence and a projection low-reflection end surface and a Cherenkov radiation type 2nd higher harmonic generating element(SHG element) are combined. The light guide 122 of the SHG element is formed in periodic gradient index structure. The LD stably oscillates having the wavelength of the fundamental wave with feedback light from the light guide 122, and the Cherenkov radiation light is generated as the 2nd higher harmonic of the fundamental wave by the SHG element. This radiation light is converted by a rear-stage Axicon lens 130 into parallel luminous flux having an annular light intensity distribution and this luminous flux is converged by a condenser lens 140 to obtain the light spot.

IPC: G06T17/40
Filed: 1985-03-22
Abstract: PURPOSE:To select easily and instantaneously a proper visual point with which a 3-dimensional image is shown in a 2-dimensional drawing, by using an auxiliary drawing expressed in a display pattern corresponding to the numerical value to show each area of an input drawing. CONSTITUTION:A drawing information input part 101 stores the forms, positions and additional numerical values of areas forming an input drawing into a drawing information memory part 102. Then the part 101 calculates the position of a proper point within the input drawing as a notice point for conversion of a 3-dimensional image into a 2-dimensional drawing and stores it in the part 102. An auxiliary drawing display part 103 converts the information given from the part 102 into a planar display pattern through a conversion part 104 to display it to a display device 106. While an azimuth scale display part 107 and a dip scale display part 108 display at a time both the azimuth scale and the dip scale to the device 106. Thus it is possible to select easily a proper visual point for display of a 3-dimensional image in the form of a 2-dimensional image.

Title: Measuring method for birefringence
Inventor: NAGATA SHINICHI
IPC: G01N21/23
Filed: 1991-03-22
Abstract: PURPOSE:To efficiently measure retardation by measuring retardation of a sample using a plurality of kinds of wavelengths and determining an optical order number from the measurement results to determine retardation. CONSTITUTION:Retardation of a sample is measured by using a plurality of kinds of wavelengths, especially four or more kinds of wavelengths, and an optical order number is determined from the relation of the measurement results (a coincidence point of measured retardation values with different wavelengths is obtained) to determine the retardation. Selection of wavelength comprises a step for measuring birefringence and a step for measuring a measurement wavelength according to the measurement results while the wavelength is changed over to another wavelength. Further, birefringence is measured with a first wavelength lambda1, and if a ratio of the minimum/maximum of transmission light intensity at this time is not a value close to 1, birefringence is measured with a second wavelength lambda2 which is comparatively close to the first wavelength lambda1. If the ratio is zero or a value close to 1, the measurement is made with a third or fourth wavelength lambda3 or lambda4 which is comparatively distant from the wavelength lambda1.

CONSTITUTION:An NMR spectrum of <14>N is measured while using a polynuclear kind Fourier transform magnetic resonance device (FT-NMR) in order to decide a relative concentration ratio of the bromine complexing agents of not less than two kinds in an electrolyte from the integral ratio of a peak area of said spectrum. <14>N has a high natural isotopic ratio and a wide range of chemical shift so that the peak of two kinds of bromine complexing agents (for instance, N- methyl, N-ethyl, morpholinium bromide and N-methyl, N-ethyl, pyrrolidinium bromide) are separated so as to be fully measured in the <14>N-NMR spectrum. Further, the measuring time of the <14>N-NMR spectrum is short as compared with the <13>C-NMR spectrum.
