Patent KR-930006425-B1 (KR)
Title: Apparatus for extracting juice
Inventor: KIM JONG-KIL
IPC: A23N1/00
Filed: 1990-08-16
Granted: 1993-07-16
Abstract: The juicer employs in its construction a ceramic material for irradiation of far infrared ray and insulation of heat and adds  a permanent magnet for the functions  of  magnetic  oscillation  and magnetic ionization. The juicer comprises  a  drive  screw  roller (6') connected to the shaft (12) of a reduction geared motor  (2), a driven screw roller (6) having a hollow (41) in its center along the whole length to house a magnet (40) and to be  filled  with  a ceramic powder (31) for low temperature use to be sealed  at  both ends, built-in magnets (30) housed within the  wall  structure  of the casing (4) including the feed hopper (3), the  magnets  having magnet shields (33) among them and the wall structure being filled with the low temperature ceramic powder  to  form  an  irradiation wall (34). In operation, latent heat in the screw  rollers  (6,6') and the wall (34) acts as the source of heat to cause  irradiation of far infrared,  the  magnetic  flux  from  the  magnets  (30,40) further promoting the irradiation  of  far  infrared.  The  juicer removes the smell and poison of vegetables.
Patent KR-930004921-B1 (KR)
Title: Credit telephone method
Inventor: TO KYONG-MIN
IPC: H04L12/14
Filed: 1990-09-07
Granted: 1993-06-10
Abstract: The method imposes call charge on credit number  input  by  a user using a service switching point.  The  method  comprises  the steps: (A) checking the credit number and the secret number  which are received by a  service  switching  point  (SSP);  (B)  sending information of the call request from a SSP to  a  service  control point (SCP) using No.7 protocol and inspecting the information  by a SCP; (C) forming a loop  to  a  receiver  and  imposing  a  call charge; and (D) calculating the sum  of  call  charges  which  are imposed during a certain period.
Patent KR-930001189-B1 (KR)
Title: Fluorescent display tube and fabrication method thereof
Inventor: KIM SONG-BOK
IPC: H01J31/15
Filed: 1990-11-29
Granted: 1993-02-20
Abstract: In  method  assembling  the  fluorescent  display  tube,  the filament supporting material (4) setted on glass substrate (2) and the contacting terminals (8,9) formed at both  sides  of  a  large number of segment electrodes (5) are crimped by glass  bar,  which is established at full length between the grass substrate and  the spacer (11). The contacting terminals have  self-restoring  force. The filament supporting material and  the  segment  electrode  are arranged in a straight line each other.

Title: Cosmetic composition
Inventor: ROSSER DAVID ARTHUR
IPC: A61K8/00
Filed: 1990-12-21
Granted: 1996-10-19
Abstract: A skin cleansing composition suitable for removing make up contains an oil which is an ester, an ethoxylated nonionic emulsifier and water, together with an aerosol propellant to deliver the composition as a mousse. The emulsifier must have an average HLB of 5 to 14, an alkyl or alkaryl moiety with 9 to 15 carbon atoms, and 2 to 10 ethylene oxide units.
