Filed: 1994-07-13
Abstract: PURPOSE:To obtain an acceleration and deceleration control apparatus by which an electric motor can be accelerated and decelerated within an overload-resistant amount without resetting the acceleration-and-deceleration time even when the flywheel effect of the electric motor driven by an inverter is changed. CONSTITUTION:An acceleration-inclination-rate upper-limit limiter 21 is installed at an acceleration inclination rate Acc which is inputted by an acceleration-and- deceleration-inclination-rate arithmetic circuit 12, and a deceleration-inclination-rate upper-limit limiter 22 is installed at a deceleration-inclination rate Dcc so as to relax the change rate of output frequent data F0 which is outputted by an output-frequency arithmetic circuit 11. An inverter output current is monitored by a current transformer 30, the respective limiters are operated only when a current value exceeds a first set value, and the change rate of the output frequency data F0 is relaxed. Alternatively, a second set value is decided on the lower side of the first set value. Inversely, the acceleration inclination rate Acc or the deceleration inclination rate Dcc is made large when the inverter output current is set at the second set value or lower. The change rate of the output frequency data F0 is made large, and of the starting time of an electric motor can be shortened.

Filed: 1991-07-02
Abstract: PURPOSE:To suppress the adverse electron shift reaction and to form a hall with high efficiency and a small loss by using the molecule which is sacrificially consumed as a medium or scattering the molecule into the medium. CONSTITUTION:A recording layer 2 consists of an electron acceptor scattered or connected to a medium, and the photosensitive molecules 2a are scattered or connected to the medium. Then the electrons are given to the molecules 2a that discharged the electrons, and the electron acceptor which accepted the electrons takes the electrons by force.

Thus a hall is formed with high efficiency by the shift of electrons caused by the light and the loss due to the adverse electron shift reaction can be evaded. In this case, polyvinyl alcohol and the photosensitive molecules 2a are used as the medium, sodium dibromide cinnamate is used as the electron acceptor and triethanol amine is used as the molecule which is sacrificially consumed, respectively.
