Title: Electric fan
Inventor: TAKAHASHI KUNIHIRO
IPC: F04D29/66
Filed: 1978-02-06
Abstract: PURPOSE: To obtain high performance and simplify manufacture and at the same time to prevent surging without lowering efficiency, by providing a cutting on the front side of each diffuser vane.  
     CONSTITUTION: Cutting 3c is provided on the front part of each diffuser vane 3a. The direction of the cutting viewed from the axial direction is nearly perpendicular  to vane 3a. Its position is in the neighborhood of the throat adjacent to the inlet of vane 3a neighboring the above-mentioned vane 3a. By this, it is possible to alleviate or prevent the occurrence of surging due to the stripping in vane 3d to be caused by the increase in the angle of encounter with respect to fiffuser vane 3a or to be caused by the flow change resulting from this. Further, by making the shape of cuttings 3c viewed from the axial direction a concentric circumference with respect to the center of the axis of rotation all cuttings 3c can be made simultaneously and thus manufacturing is simplified.

Title: Cleaning device for refrigerant system
Inventor: SEKIDA MASUMI
IPC: F25B47/00
Filed: 1993-01-27
Abstract: PURPOSE:To improve cleaning effect by a method wherein a bypass circuit is provided to introduce high pressure refrigerant gas which has passed through a high pressure oil separator to a connection valve on a supply side, and the high pressure refrigerant gas from the bypass circuit and refrigerant liquid from a high pressure receiver are supplied alternately. CONSTITUTION:A solenoid valve 12 is closed while another solenoid valve 12 is opened by a timer at a properly set time interval. At this time, a high pressure gas refrigerant is sent from a discharged oil separator 5 through the solenoid valve 14 and a supply side connection valve 15 as it is in a gaseous state to a refrigerant system 100 which is to be cleaned, so that it may drive liquid refrigerant supplied there for its cleaning at a high speed. A check valve 13 works to prevent the high pressure gas refrigerant from flowing back to a high pressure receiver 11. By sending the liquid and the gas refrigerants alternately to the refrigerant system 100 which is to be cleaned, a refrigerant flowing volume is increased and a refrigerant flowing speed becomes high, and therefore a compressor 4, though of a small capacity, can increase a cleaning effect.
