Abstract: PURPOSE: A load compensating method of a hydraulic elevator is provided to improve travel stability, to prevent accidents by sudden falling at an emergency or under repairs, and to protect against shock at driving by restricting motor output for supplying normal pressure to a hydraulic circuit and preventing a hydraulic pump pressure from rising suddenly. CONSTITUTION: A first load compensation mode limitedly outputting a current command value of a motor is performed in an initial load compensation mode to equalize hydraulic cylinder pressure with hydraulic pump pressure. The motor is driven with normal output by regularly supplying pressure to a hydraulic circuit with low pressure. The other mode is performed in a non-load compensation mode. Cylinder pressure, pump pressure, and motor speed are detected, and the motor is driven with restricted output. In a second load compensation mode, the motor is driven with normal output after performing the first load compensation mode. The load compensation stages are finished after checking the end of the load compensation.

Abstract: PURPOSE: An OTR(Over-The-Range) is provided to keep a microwave oven clean by making a front face of an OTR cleaned easily and to reduce noise transmitted forwardly from a ventilating motor. CONSTITUTION: An OTR embeds a ventilating motor(12) for discharging air in the lower portion through the inside of a body. Air discharged via the ventilating motor is discharged via a ventilation unit(14) formed on the front upper face of the microwave oven. As a grille is not formed in the front upper face of the microwave oven, the contamination of the front face is prevented. The noise generated from the ventilating motor is guided to the front of the microwave oven and discharged through the ventilation unit instead of being directly discharged through the front face of the microwave oven. Thus, noise is reduced. Additionally, a guide member for guiding air to the ventilation unit is installed to prevent generation of a swirl. Therefore, smooth airflows are formed.
