Title: Ventilator
Inventor: MATSUSHITA KAZUMI
IPC: F24F7/04
Filed: 1978-06-30
Abstract: PURPOSE: To minimize the heat loss and improve heating efficiency by absorbing heat from the hot air being discharged outside at ventilation, and by furnishing this absorbed heat to the cold air induced from outside.  
     CONSTITUTION: When the air flows to the direction a, it passes thru louver 10 which is installed on a side 9 of eaves 7, and the outside air flows into the room along the arrow b, while the warm air being heated inside the room is discharged outside along the arrow c passing thru the discharge port 4, and louver 10 which is installed on the other side 9 of eaves 7. In the course of this air movement, warm air being heated inside of the room is deprived of its heat at the end part of discharge port 4 of heat pipe 5, and the air discharged outside is of low temp. Heat being absorbed by heat pipe 5 moves to the other end of the heat pipe 5 along the arrow d, and the outside air flowing inside thru air intake port 3 contacts with the  other end of heat pipe 5, and subsequently warm air is available inside the room.

Title: Felt filter medium
Inventor: KURODA TOSHIYASU
IPC: B01D39/14
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a filter medium having satisfactory dimensional stability at high temp. by using base cloth made of twisted yarn of org. and inorg. fibers. SOLUTION: Base cloth made of twisted yarn of org. and inorg. fibers is used. Since the org. fibers are more liable to elongate than the inorg. fibers, at the time of entanglement in the barb part of a barbed needle, the org. fibers elongate without breaking and reduce the damage of the base cloth, accordingly a satisfactory effect is produced without increasing the number of the org. fibers implanted. Since the inorg. fibers are stable to heat, the objective filter medium less liable to heat shrinkage and elongation even at a high temp. of >=150 deg.C and having high heat stability is obtd. When polytetrafluoroethylene fibers are used as the org. fibers, the effect is remarkable. When carbon fibers are used as the inorg. fibers, trouble due to static electricity is suppressed.
