  • Patent number: 10895155
    Abstract: A package type compressor includes a housing, a compressor, a motor, an inverter, and a cooling fan. The housing has an air inlet. The compressor is disposed inside the housing where it compresses the air. The compressor is disposed in a compressor body inside the housing. The motor is disposed above the compressor inside the housing, and drives the compressor. The inverter is disposed in the region of the air inlet of the housing, and controls a rotation speed of the motor. The cooling fan is disposed inside of the compressor body. The cooling fan generates a flow path of cooling air within the package type compressor. The inverter is disposed in such a way that as the flow path of cooling air enters the air inlet of the housing, the flow path of cooling air passes directly over the inverter thereby cooling the inverter.

  • Publication number: 20080139686
    Abstract: Highly weatherable, moisture-curable, one-component polyurethane composition which is curable with moisture in the air is provided at lower costs. The composition contains a main component which will form a polyurethane resin upon curing, and additives. The additives are one or more photocurable materials selected from the group consisting of unsaturated acrylic compounds, polyvinyl cinnamate, and azide-containing compounds; and a hindered amine photostabilizer. The additives may preferably further contain a thixotropy endowing agent comprising a blocked amine compound forming primary or secondary amino group with moisture, or a polyurea compound.
