Title: Dc/ac converter
Inventor: KUME TSUNEO
IPC: H02M1/14
Filed: 1992-02-20
Abstract: PURPOSE:To provide a DC/AC converter in which ripple is suppressed by connecting an LC filter, tuned with n-th higher harmonic (n is an odd number) of switching frequency, in parallel with a smoothing capacitor thereby reducing the capacitance of the smoothing capacitor. CONSTITUTION:Basic wave component of ripple current produced through switching of a transistor 4 is absorbed through an LC resonance circuit of a reactor 2 and a capacitor 3. Since main component of ripple has carrier frequency, it can be absorbed through the LC resonance circuit of the reactor 2 and the capacitor 3. When current ripple of a chopper or a PWM inverter is absorbed through the LC resonance circuit, capacity of smoothing capacitor can be reduced significantly resulting in a downsized DC/AC converter having prolonged service life.

IPC: B41J2/175
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder in which ink can be prevented surely from being solidified in a cap without lowering the recording speed or increasing ink consumption. SOLUTION: Since ink solvent S is fed from an ink solvent feeder 70 into the cap 181 of a capping unit 18 being discharged with ink from the nozzle 111 of a recording head 16, ink is not solidified in the cap 181 even it ink is not discharged frequently from the recording head 16 into the cap 181. Consequently, an ink absorbing member 182 in the cap 181 does not lose the function thereof. Since wet state prevails constantly in the cap 181, ink in the nozzle 111 can be prevented surely from being solidified by the vapor of the solvent S when the nozzle forming face 160 of the recording head 16 is covered with the cap 181.
