Abstract: A complementary Lateral Insulated Gate Rectifier (LIGR) includes two complementary LIGR structures fabricated in adjacent surface-adjoining semiconductor wells of the same conductivity type in a semiconductor substrate. The two LIGR structures are of generally similar configuration, thus simplifying the manufacturing process, and the proposed design additionally permits the n-channel and p-channel LIGR structures to have comparable "on" resitances. The two LIGR structures, otherwise isolated by a portion of the substrate separating the two semiconductor wells, are connected together by a common source electrode. The resulting complementary Lateral Insulated Gate Rectifier features a compact, integrated structure in which the "on" resistances of both the n-channel and p-channel portions of the device are comparable.

Abstract: The automatic process for  rolling  laver  rice  comprises  a process for feeding a laver sheat, a process  for  placing  boiled rice on the laver, a process  for  rolling  rice,  and  a  cutting process. The processes are performed by a  motor.  When  a  boiled rice and a dish are cut short, the operation of the  motor  stops. The motor is drived again after a rice box  and  a  dish  box  are exchanged.

Title: Method for corona discharge treatment for the preparation of polymeric surface having a wettability gradient
Inventor: LEE HAE-BANG
IPC: C08J7/00
Filed: 1990-10-08
Granted: 1993-06-01
Abstract: This invention  relates  to  corona  discharge  treating  the surface of polymeric material (e.g., polyethylene,  polypropylene, polystrene,    polyvinyl    chloride,    polyester,     polymethyl methacrylate, synthetic rubber, natural or synthetic fiber,  wood, paper, etc.) to give hydrophilic property. The polymer  is  corona discharge treated by moving the bed (2) at  an  uniform  speed  of 0- 10 cm/sec and simultaneously generating the amplitude  of  radio frequency oscillator (1) to 0-200 V for 0-10 sec.

Title: Adhesive compositions for tire cords
Inventor: KIM SE-HUN
IPC: C09J161/12
Filed: 1990-12-19
Granted: 1993-11-24
Abstract: The compsn. consists of RF acidic initiation  condensate  (A) of formula (I), vinyl pyrridine  (B),  phenol  based  binder  (C), ammonia, and isocyanate resin  (D).  The  following  condition  is satisfied; the adhesive composition (E) comprises 16-21 wt.% solid component; A/E (wet wt) = 1.9-2.2 wt.%; B/E (wet  wt.)  =  5.5-6.5 wt.%; C/E (wet wt.) = 9-12 wt.%; and D/E  (wet  wt.)  =  0.09-0.12 wt.%. In the formula (I), m = 0.3-1, n = integer of 0-9. The obtd. compsn. improves heat-resistant adhesive strength.
