Disclosed are compounds of the formula 1or the pharmaceutically acceptable non-toxic salts thereof wherein: W represents substituted or unsubstituted aryl or heteroaryl; T is hydrogen, halogen, hydroxyl, amino or alkyl; X is hydrogen, hydroxy, or lower alkyl; m is 0, 1, or 2; n is 0, 1, or 2; and R3 and R4 represent substituted or unsubstituted organic residues. The digital signal generator is adapted for supplying a digital bit sequence selected among, at least two, bit sequences stored in the memory whereby the strength of the magnetic field generated by the transmitter coil can be varied dependent on the bit sequence selected by the control unit. This system improves processing medical data, patient care, and financial information. The spring element acts between the pressure element and the receiving part and allows the pressure element to be introduced from the top end but withstands against removal of the pressure element through the top end. The nanosized phosphor is featured in that at least 90% of total particles have a particle size of 1 to 100 nm and an electrostatic charge of the total particles is in the range of \u221220 \u03bcCg to 5 \u03bcCg. The pressing member has a hole portion allowing the plastic melted by the heating unit to pass through, and separates aluminum and the plastic by pressing the processing target accommodated in the container.
