Abstract: PURPOSE:To obtain a digital speed controller capable of constantly stable draw control, by a method wherein the speed fluctuation due to a current beat generated when the power frequency and the motor frequency of a commutatorless motor approach to each other is removed by using a computer. CONSTITUTION:A line speed reference voltage VMRH is outputted after being calculated in a computer 51 into which necessary line speed values are fed through a push button 3 (4) for increase (decrease) of the line speed. Moreover, necessary draw values are fed into the computer 51 through push buttons 17 (18) for draw increase (decrease) of corresponding sections S1-Sn, and set draw portion speeds are calculated therein and delivered. The set draw portion speed signals N'AD1t- N'ADnt of the respective sections are added to the line speed reference voltage VMRH to become speed references of the respective sections. A deviation is obtained by comparing each of the speed references with the speed feedback voltage  delivered from a position detector 9d of each of synchronous commutatorless motors  9 through an F-V converter 12. According to the deviation amplified by each of amplifiers 13, the output voltage and frequency of each of thyristor power supply  devices 14 are controlled.

The multilayer container main body and the lid material 4 are heat-sealed in a hardly released state at a flange part 3. Recessed seal parts 6, 7 are formed to the inside and outside ends of a heat-seal part 5. When a tab part 8 is raised, release is started between the innermost layer 1 and the layer 2 brought into contact therewith from the part of the recessed seal layer 7 and, in succession thereto, the innermost layer of the outer edge of the heat-seal part is cut and release advances between the innermost layer 1 and the layer 2 brought into contact therewith and the innermost layer is released up to the part of the recessed seal part 6 to release the lid material. Therefore, the lid material 4 and the multilayer material is good in sealing performance performance and the container can be easily opened.
