Filed: 1980-12-26
Abstract: PURPOSE:To maximize the oprating efficiency of an inverter irrespective of the set rotating speed and the magnitude of a load without necessity of an additional circuit by simply calculating without storing a pulse pattern to obtain a pulse width modulation waveform. CONSTITUTION:A microprocessor CPU9 reads the number n3 of basic pulses determined by the maximum efficiency operating frequency for each operating frequency of an operating frequency setting unit 8 from a memory ROM10, and sets it to an external frequency divider 12. On the other hand, since a basic oscillation frequency f0 from a reference oscillator 11 is applied to the frequency divider 12, the frequency f0 is divided by 1/n3, and is inputted to an external timer 13. The CPU9 unloads the ON time duration of voltage application and OFF time duration from a memory RAM14 and outputs them to a gate circuit 15, thereby controlling a main circuit controller 7. The CPU9 further calculates the time duration of a gate signal from the period of time up to the time up of the timer 13, the signal of a rotating speed detector 3 and the signal from the unit 8, and stores it in the RAM14.

Title: Electrolyte for electrolytic capacitor
Inventor: SHIMIZU MAKOTO
IPC: H01G9/035
Filed: 1987-07-24
Abstract: PURPOSE:To obtain an electrolytic capacitor which is long-lived at a high temperature and whose electrical characteristic is excellent by a method wherein a tetraalkyl ammonium salt of succinic acid is contained as an electrolyte in a non-proton solvent or in a mixed solvent where the non-proton solvent as a main component is mixed with a polyvalent alcohol. CONSTITUTION:A combination of an electrolyte and a solvent is basically arbitrary; the solubility of some of tetraalkyl ammonium salts is low in relation to a non-proton solvent; in this case, a mono salt is used as the electrolyte; a mixed solvent where the non-proton solvent as its main component is mixed with a polyvalent alcohol is used as the solvent. Because the tetraalkyl ammonium salt of succinic acid as the electrolyte is contained in the non-proton solvent or the mixed solvent where the non-proton solvent as a main solvent is mixed with the polyvalent alcohol, the electrolyte of high conductivity is obtained; an internal resistance value of an electrolytic capacitor is lowered; water is not contained essentially; accordingly, a deterioration in a characteristic is reduced even after it has been used for many hours at a high temperature.
