Title: Communication system for ciphered control signal
Inventor: NOGUCHI YOSHIRO
IPC: H04L9/20
Filed: 1992-05-08
Abstract: PURPOSE:To devise the ciphered control signal not easily decoded by revising random number series data used for ciphering the control signal as required. CONSTITUTION:One random number key generating section is selected from plural random number key generating sections 2c, 2d generating prescribed random number data, and a control signal is ciphered at a control signal ciphering circuit 2f based on random number data generated by the selected random number key generating section. Moreover, random number key identification data representing the random number key generating section used for the ciphering are added to the ciphered control signal. Then the ciphered control signal with the random number key identification data added thereto is sent/received between a master station 2 and a slave station 8 to implement the communication, a control signal decoder 9 extracts the original control signal based on the random number key identification data from the ciphered control signal and decodes it. Thus, the ciphered control signal is not easily decoded.

Filed: 1985-06-28
Abstract: PURPOSE:To enable to use an induction motor as a drive source of a winding machine by maintaining the DC side power of an inverter constant so that the relationship between the rotating force and the rotating speed is inversely proportional. CONSTITUTION:A multiplier 4 calculates the product VXI of the current I and the voltage V of the DC side of an inverter 2.

When the DC side power of the inverter 2 is maintained constant, the effective power of an induction motor 1 is held constant. Accordingly, the rotating force and the rotating speed of the motor 1 becomes inversely proportional.

Abstract: O A display arrangement utilises a fluorescent screen 3 to provide readily alterable bright displays. The arrangement can provide a fairly large display surface, but can be of very small thickness. It contains electron emissive cathodes 5, and field electrodes 7 positioned closely adjacent to the cathode to control the emission of free electrons. Electrons which are freely emitted are accelerated to a mesh electrode 4 which is held at a modest positive voltage. A fluorescent screen 3 having a positive potential of several thousand volts is positioned closely in front of the mesh electrode. The preferred embodiments of the invention, a number of separate cathodes and/or separate field electrodes are provided, so that selected regions of the screen can be illuminated to provide desired display patterns. Individual regions of the screen can be switched on and off (i.e. rendered bright or dark) by the application of very low switching potentials to the field electrodes and/or the cathodes.
