ROTARY HEAT TREATMENT FURNACE

SANKEN SANGYO CO., LTD., ...

1. A rotary heat treatment furnace comprising: a furnace body having an inside that is partitioned into a first zone and a second zone; a housing rotary body rotatably supported and disposed so as to straddle the first zone and the second zone, the housing rotary body including: a plurality of side walls extending radially; a plurality of housing chambers partitioned by the side walls, the housing chambers each having a substantially same size, the housing chambers being disposed circumferentially in multiple stages, each of the multiple stages including multiple housing chambers; and a space disposed in the central portion of the housing rotary body so that the housing rotary body is provided with a donut shape in plan view; a rotary driving device for rotating the housing rotary body; a heating device for heating the air inside the furnace body; a fan for feeding hot air prepared by the air heated by the heating device to the housing rotary body; a first partition wall and a second partition wall, the first partition wall extending from the fan towards the housing rotary body while the second partition wall extending from a wall surface of the furnace body towards the housing rotary body, the first partition wall and the second partition wall together partitioning the inside of the furnace body into the first zone and the second zone; a first flow passage communicating a blowout port of the fan with outer circumference sides of the housing chambers positioned in the first zone; and a second flow passage communicating outer circumference sides of the housing chambers positioned in the second zone with a suction port of the fan, wherein: when the first partition wall is in such a state that an end portion thereof at a side of the housing rotary body side comes closer to one of the side walls, the second partition wall is in such a state that an end portion thereof at a side of the housing rotary body comes closer to another one of the side walls; the hot air provided by the fan and passed through the first flow passage is fed substantially horizontally to the outer circumference sides of the housing chambers positioned in the first zone and further to the space side; and the hot air is then fed substantially horizontally from the space side to the outer circumference sides of the housing chambers positioned in the second zone, and is returned to the fan through the second flow passage.

DRUG-ELUTING COATINGS APPLIED TO MEDICAL DEVICES BY SPRAYING AND DRYING TO REMOVE SOLVENT

Abbott Cardiovascular Sys...

1. A method of drying a stent having a longitudinal axis, comprising:using a dryer having an inlet conduit for supplying an input gas and a nozzle exit for producing a heated, drying gas, the nozzle exit having apertures; and
placing the stent between a reflector and the nozzle exit, wherein the reflector is arranged to cause an increase in gas pressure near the stent by directing gas towards the stent, thereby reducing heat loss in the vicinity of the stent;
wherein the dryer is adapted for producing a substantially uniform drying air mass over the stent length.

REFRIGERATOR AND METHOD FOR CONTROLLING THE SAME

SAMSUNG ELECTRONICS CO., ...

1. A refrigerator comprising:a compressor;
a condenser configured to condense refrigerant compressed by the compressor;
a freezing chamber evaporator and a refrigerating chamber evaporator connected in parallel to each other at an outlet of the condenser;
a flow passage switching valve configured to switch a flow passage of the refrigerant in a manner that the refrigerant flows toward one of the freezing chamber evaporator and the refrigerating chamber evaporator;
a temperature sensor configured to detect an outdoor air temperature; and
a controller configured to
when an operation of the compressor is started at a first time and prior to expiration of a first time period, control the flow passage switching valve in a manner that a first refrigerant recovery operation from one of the freezing chamber evaporator and the refrigerating chamber evaporator is performed, and
determine a second time at which the operation of the compressor is to be stopped and control the flow passage switching valve in a manner that a second refrigerant recovery operation from the one of the freezing chamber evaporator and the refrigerating chamber evaporator is performed during a second time period prior to the second time,
wherein the controller variably controls the first time period of the first refrigerant recovery operation and the second time period of the second refrigerant recovery operation according to the detected outdoor air temperature.
