Title: Pulse width modulation inverter
Inventor: KATSUTO MASAYUKI
IPC: H02M7/48
Filed: 1985-09-30
Abstract: PURPOSE:To enable a motor to be driven without deteriorating the torque characteristics regardless of any increased load current by a method wherein any voltage fall by the effect of shortcircuit prevention term due to any pulse width modulation is corrected. CONSTITUTION:Any voltage correction value DELTAV2 for a power factor angle phiis preliminarily calculated meeting the modulation requirements to be stored in the second voltage correction circuit 90. The voltage fall correction value DELTAV2 by the effect of short-circuit prevention term is calculated by inputting a power factor angle phi from a power factor detector 80. Resultantly, the Vo command inputted into a PWM circuit 40 becomes the sum of a voltage command outputted from a V/f pattern setter 30 and values DELTAV1, DELTAV2 outputted from voltage correction circuits of the first and the second voltage correction circuits 70, 90. Therefore, the vacancy magnetic flux of motor can maintain the proper value under no influence of increased load to secure the output torque value.

IPC: B41J2/19
Filed: 1983-11-18
Abstract: PURPOSE:To prevent minute bubbles from entering into a pressure chamber by applying pressure to supply ink and by dissolving these minute bubbles in ink to remove. CONSTITUTION:Ink in a supply route 6 is entered into a pressure pump 4 from an ink tank 1 and sent by pressure into a reservoir 8 through the ink supply route 6. A pressure reducing filter 11 is provided within the reservoir 8 and the pressure of the ink is reduced to the point lower than the pressure reduced by surface tension caused by a nozzle 14, and the ink is supplied. Considering a flow resistance from the ink supply route 6 toward the pressure reducing filter 11, the resistance is larger than that of an ink return route 10, resulting in a tendency of the main flow of ink into the ink return route 10 through the reservoir 8. The ink sent through the return route 10 is sent to the pressure pump 4 and sent out again into the ink supply route 6 by pressure. As stated above, the ink is sent by pressure through the whole system of the circulation, and therefore, minute bubbles are dissolved in the ink and they can be effectively removed therefrom.
