Title: Inverter unit for room air-conditioner
Inventor: MOCHIZUKI SHOJI
IPC: H02M7/48
Filed: 1989-12-13
Abstract: PURPOSE:To suppress noise without increasing carrier frequency by cancelling noise of the carrier frequency with sound having reverse phase at the time of DC/AC conversion. CONSTITUTION:A PWM signal generator 8 transmits a switching signal having carrier frequency to a DC/AC converter 7 according to frequency and voltage corresponding to an air-conditioning load. Consequently, a PWM signal generator 8 applies a pseudo-AC waveform onto a compressor 5 while simultaneously transmits a PWM signal to a modulation circuit 10. The modulation circuit 10 converts the PWM signal into a signal having reverse phase. Consequently, carrier frequency noise from the compressor 5 is cancelled by sound from a speaker 12 having same frequency and reverse phase at the time of DC/AC conversion. By such arrangement, noise can be suppressed without increasing carrier frequency at the time of DC/AC conversion.

IPC: B60J5/04
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a sealed structure of the upper end of a partition sash which can completely prevent the entrance of water without adding other sealant. SOLUTION: An in-vehicle remaining part 20 is left in a position adjacent to a notched part 19 and therefore water that may enter along the upper edge of the partition wall part 18 of a partition sash 10, once falling into the notched part 19 and reaching its bottom edge, cannot go up the vertical edge of the in-vehicle remaining part 20 but is forced to directly pass through the cross section of the partition sash 10 and discharged downwards and so cannot enter the interior A of the vehicle. Thus, there is no need to add other sealant as it should in conventional cases, and so an increase in the number of part items and deterioration of mounting work are avoided.
