Inventor: SUGIYAMA ATSUSHI
IPC: G09F9/30
Filed: 1988-01-14
Abstract: PURPOSE:To simplify the constitution of an optical shutter by using the optical shutter with dividing into the respective colors of R, G and B. CONSTITUTION:From the panels of respective optical shutter 106-108 corresponding to the three primary colors of R, G and B, a fiber 105 is connected respectively to R, G and B dot trio for each picture element of a display surface. Thus, for example, by using a method to use a light source, to which a color filter is mounted, or to use a light from the light source with separating the light into the respective colors by using a spectral element singly or with being coupled so as to correspond the three primary colors of R, G and B, without providing a fine color filter layer to correspond to the respective picture elements on the panels of the optical shutters 106-108, the title device can correspond to a coloring.

Title: Stopping system for synchronous motor
Inventor: KAWADA SHIGEKI
IPC: H02P3/22
Filed: 1982-01-20
Abstract: PURPOSE:To rapidly stop in emergency a synchronous motor by integrally constructing a plurality of yokes provided at an equal interval around a shaft provided at the center of a stator, and shortcircuiting the drive voltage input line of the motor. CONSTITUTION:When a malfunction occurs, switches SW1-SW3 are simultaneously tilted down to the lower side in the drawing. As a result, three drive voltage input lines of a synchronous motor 10 are accidentally shortcircuited. The current which flows through the coil of the stator 1 at this moment rises at the time constant of the coil impedance, and the variation in the magnetic flux generated at the stator 1 side introduces the variation in the magnetic flux in a magnetic circuit in the yokes 2-1-2-6 at the rotor side. Accordingly, since the yokes 2-1-2-6 are formed in an integral structure, large eddy current loss is generated, and is operated as the initial braking energy.
