Title: Aurora production device
Inventor: MINAMI SHIGEYUKI
IPC: G09B23/06
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to reproduce the aurora phenomenon in the upper atmospheric layer by placing a particle generating section and a magnet in a vacuum device on the ground. SOLUTION: The simulated earth consisting of the particle generating section and the magnet is set in a vacuum vessel. Particles are jumped out of metal and an accelerated by an electric field in the particle generating section. The magnet is made conductive on its circumfrtrnce so that the electric field is impressed between the magnet and the particle generating section. The vacuum vessel is used and many needle-like electrodes are laced in the upper part of the vessel. Aurora particles are generated by the electric field release by the high voltage impressed on these electrodes. The pressure in the vessel is set near the atm. pressure in the upper atmosphere of the earth. Electric discharge is generated by the electric field impressed between the needle-like electrodes and a conductor formed simulating the earth.  Light emission having the same line spectrum as that of the aurora is thereby reproduce. The fact that the forms of the light emission around the earth are entirely different is indicated by converting the polarity of the particle generating section to positive and negative polarities. The light emission occurs in a disk shape on the equatorial sky so as to surround the earth if the electrodes of the generating section are set positive. The light emission has the form along both south and north magnetic poles and is visible like curtains from the ground if the electrodes are set negative.

Title: Method for correcting driving parameter of weighing machine
Inventor: KANO IKUO
IPC: G01G13/08
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To continuously enable a weighing machine to weigh an object to be measured, while the weighing accuracy of the machine is maintained by automatically correcting the driving parameters of the machine, so that the difference between the time elapsed until the machine reaches a set indiscrete value and standard elapsed time may be reduced. SOLUTION: After such a vibrational strength S that reaches a damping starting amount B after a standard elapsed time TSs is found by weighing a standard object to be weighed in advance and another vibrational strength F that reaches a target amount A after another standard elapsed time TFs is found by damping the vibrational strength after the damping starting amount B has been reached, the strengths S and F are used as standard parameters. When the change with time of the indiscrete value is measured while weighing is performed by using the parameters, the driving parameters are brought nearer to small driving strengths S-1 and F-1 when the supply of an object to be weight is excessive, because the damping starting amount B and target amount A are reached in elapsed time TS1 (TS2 ) and TF1 (TF2 ) shorter (longer) than the standard elapsed time TSs and TFs . When the supply is insufficient, the driving parameters are brought nearer to the standard elapsed time TSs and TFs by changing (correcting) the parameter to larger driving strengths S+1 and F+1 .
