    摘要: A pulse motor for clockworks and the like in which the rotor comprises two spaced-apart permanent magnetic disks mounted upon a common shaft and rotatable with respect to a stator. The stator comprises a respective pair of magnetic poles in the plane of each disk, the poles of the pair being interconnected by a shank and a coil wound upon the respective shanks, the coils lying on opposite sides of the rotor. The coils can be excited independently to cause the respective pair of poles to magnetically cooperate with the respective disk and rotate the motor in the forward or the reverse sense.

    摘要: A gamma correction device performs gamma correction on an input signal from an image capturing element based on at least one correction curve having a predetermined input-output characteristic in an image capturing apparatus. The correction curve is composed of a logarithmic curve whose slope at the origin is 5.0 or less or a composite of a curve segment lying from the origin to a predetermined level of an input signal complying with the ITU-709 standard and a logarithmic curve segment lying above the predetermined level of the input signal, wherein both curve segments are continuously combined and have the same slope at the predetermined level.

    摘要: The present invention relates to a high-temperature microscope. According to this invention, a specimen is held in vacuum with one side of it heated through exposure to an electron beam and the other side of it observed through an observation window.A curtain of inert gas is formed between the specimen and the observation window to prevent the window from being clouded, i.e., to prevent vapor deposit on the window from the specimen.Visual observation (including photography) and measurement of the specimen temperature by heat radiation therefrom are done individually with different bands of wavelengths. For the purpose of illuminating the specimen, beams of spectral distribution containing the components of in the visible band for observation are used but no components of the temperature-measuring band are utilized as light source. For the purpose of visual observation, a narrow visible band contained in the aforesaid beam located in low brightness in the heat radiation beams from the specimen is utilized.
