    摘要： Plural lines on a surface of a photosensitive body of an electrophotographic image formation apparatus are simultaneously scanned by plural laser beams for image formation. Each of a pair of semiconductor lasers 11a and 11b biased in an ON state is independently turned on. A surface potential of the photosensitive body in each case is measured by a measurement unit such as a surface potential sensor 30, a surface potential detection circuit 31 and an A/D conversion circuit 32. Based on the measured result, an operational current of each laser is determined by a CPU 33 such that the surface potential of the photosensitive body becomes a target-potential, e.g., 220V to 230V. An image pattern difficult to be influenced by the laser start characteristic and an image pattern easy to be influenced by the laser start characteristic are formed, and the formed image patterns are respectively measured so that the current supplied at no beam emission time is controlled according to the measured results.

    摘要： A liquid crystal display with multiplex capability enhanced by decreasing the hysteresis characteristic of the liquid crystal. The hysteresis characteristic of the crystal is reduced by fixing an angle of twist of the liquid crystal molecules in the range of 270 to 315 degrees, by setting a birefringence (.DELTA.N) of the host molecules at less than or equal to 0.14 and by having a crystal layer thickness (d) of less than or equal to 7 .mu.m (.DELTA.n.multidot.d

    摘要： A position management system includes a first receiving unit configured to receive a radio wave according to a predetermined wireless communication standard from a first device when the movement of a second device is detected; a second receiving unit configured to receive second position information including latitude and longitude information from an IMES transmitting device when the movement of the second device is detected; and an acquiring unit configured to measure an intensity of the received radio wave, estimate a position of the second device based on the intensity, and acquire first position information indicating the estimated position. The second receiving unit receives a radio wave from GPS when the second device moves outdoors where communication with the IMES transmitting device is not possible, and sets latitude and longitude information, which is measured based on the radio wave received from the GPS, as the second position information.

    摘要： A phase compensator having a biaxial birefringent component (40) is fabricated by oblique deposition of an inorganic material on a base plate (69). A polar angle of an evaporation path of the inorganic material is controlled in a predetermined angular range to a surface normal of the base plate (69). In the oblique deposition process, the base plate (69) is oscillated in a horizontal direction. The phase compensator is arranged such that its slow axis (L4) is perpendicular to a slow axis (L3) of tilt components (24a, 24b) in a liquid crystal panel (20), and that an index ellipsoid (41) is tilted in an opposite direction to a tilt direction of the tilt components (24a, 24b).
