Granted: 1991-01-24
Abstract: The method is for balancing the  laundary  in  the  automatic washing machine. When the water is  drained  about  two  third,  a water level sensor (2) detects it and starts to turn  the  washing drum gradually so that the laundary is attached uniformly  on  the inner wall of the washing drum by the rotating water  power.  When the water is empty, a microprocessor (1) turns  the  washing  drum with normal speed to dehydrate.

Title: Hot water separating device
Inventor: KANG TAE-KAE
IPC: B23P15/00
Filed: 1991-12-31
Granted: 1994-06-01
Abstract: The method of manufacturing hot-water distributing apparatus for supplying hot-water heated from the boiler in multiple directions, is composed of cutting the tube of a diameter into pieces (2) of a certain length; fitting a tube piece (2) over a stationary die (6) having holes (5) corresponding in number to an inlet (3) and outlets (4), supporting the die by support rod (7), descending the compression die (10) having integral units each consisting of a drilling pin (8) and a mouth expanding member (9) for drilling holes; forming the inlet and outlets by the mouth expanding members; cutting thread (12) on inner bent sections (11) of the inlet or outlets on one ena; welding a cover plate on other end of the tube.
Patent KR-0167111-B1 (KR)

Title: Hydrazine derivative and pesticidal composition comprising said derivative as an effective ingredient
Inventor: YANAKI MIKIO
IPC: C07D311/12
Filed: 1992-01-23
Granted: 1998-12-01
Abstract: A novel hydrazine derivative represented by the following formula (I): <CHEM> where R<1> -R<1><2>,A,B and n are as defined in Claim 1, and a pesticidal composition containing the hydrazine derivative as the effecting ingredient. The hydrazine derivative show high pesticidal activity against harmful pests which are resistant to known pesticides such as organophosphorus pesticides, pyrethroids, etc., especially against Lepidopters harmful pests such as Plutella xylostella, Spodoptera litura, Cnaphalocrocis medinalis, Adoxophyes orana, etc., and is effective for controlling harmful pests in paddy field, upland field, orchard, forest or places to be kept environmentally hygienic.
