A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.

Lithographic printing form precursors comprising positive working polymeric coatings on substrates may during storage or transportation undergo undesirable changes in their imaging properties. It has been found that acceptable properties can be restored by carrying out a heat treatment which involves a relatively short heating stage followed by accelerated cooling.

The magnetic pole position detector for an electric motor comprises a detection rotor, a detection stator, and magnetic flux concentration tips and magneto electro transducers. The detection rotor is fixed to an axis of rotation of the motor and comprised of disc-like rotors having first toothlike protrusions and a permanent magnet. The disc-like rotors are assembled so as to make the first toothlike protrusions coincide in the axial direction and the permanent magnet is fixed between the disc-like rotors. The detection stator is comprised of stator cores comprised of an annular yoke and stator teeth formed at regular intervals on the former. Second toothlike protrusions are formed on the inner end of the stator teeth. The stator cores are assembled with a gap in the axial direction so as to make respective second toothlike protrusions coincide in the axial direction. The magnetic flux concentration tips and the magneto electro transducers are placed in the gaps in the axial direction. The detection rotor and the detection stator are assembled with a gap in the radial direction. The magnetic pole position is obtained by detecting the magnetic flux flowing through the stator teeth that varies in accordance the rotation of the detection rotor.
摘要:
Even if various types of images exist together in an objective image, it is possible to sufficiently improve the quality of the image at all areas which are to be corrected. An image-correction apparatus has such a structure in which a CPU (10), an image-correction procedure part (12), a color monitor (14), a key board (16), a mouse (18), an inputting device (20), an image memory (22), an image-correction method memory (24), an outputting device (26) and the like are connected to a main bus (50). First, the CPU (10) instructs the inputting device (20) to read the objective image and store resultant data in the image memory (22), and instructs the color monitor (14) to display the objective image, using the image data which are stored. An operator then designate areas to be corrected, and selects a image-correction method which is suitable to the area from four types of image-correction methods, i.e., one for correcting a photograph, one for correcting a black letter against a white background, one for correcting a white letter against a black background and the other for correcting a thin line, while observing the screen display. The image-correction procedure part (12) executes the designated image-correction method on the designated area. The CPU (10) instructs the outputting device (26) to output an image which is expressed by image data which are obtained after execution of the image-correction procedure.
