Patent KR-850001852-B1 (KR)
Title: Label releasing device
Inventor: SATO YO
IPC: B41K3/44
Filed: 1982-12-22
Granted: 1985-12-28
Abstract: Many labels are adhered to a label tape(I). a hole(6) penetrates the tape between the labels(3). This tape is established on a tape supplier(22) and transported to the label releasing device(23). A conveying portion(24) has a conveying drum(26) and a hook(27) which are assembled with the two body plates(11a, 11b) by a pivot(25). This drum has pins which join with the label tape holes. The releasing portion(30) has an upper part, attached on the body plates, and an under part, attached on a moveable bottom cover. The label tape is supplied between these parts. The labels are released from the tape by converting the label band(2). A release helping app. is attached on the bottom cover and provides a little clearance between the releasing portion of the label and the tape.
Patent KR-860000349-B1 (KR)
Title: Method for producing cube-on-edge oriented silicon steel
Inventor: MILLER ROBERT F
IPC: H01F1/16
Filed: 1983-03-03
Granted: 1986-04-12
Abstract: Cube-on-edge-oriented silicon steel is produced by hot rolling, cold rolling with intermediate annealing to final gauge, normalizing to effect decarburisation and primary recrystallisation and, finally, texture annealing. The process is improved by uniformly light cold rolling deformation of 0.5-5 % redn. just prior to final texture annealing to reduce grain size. The process reduces permeability at high induction levels and grain size during final texsture annealing. Core losses and watt losses are also reduced by reducing the sheet thickness.

Title: Sulfite digester rate of delignification system
Inventor: JOHNSON RALPH K
IPC: G01N31/00
Filed: 1983-11-01
Granted: 1988-05-04
Abstract: The degree of cooking in a sulphite digester for delignification reactions, is determined by continuously calculating the digester reaction rate as a function of sensed idgester temp. sensed digester pressure and several constants which include an energy-of-activity constant and the gas constant of the digester reaction, so that reaction rate value is obtd. over a time period. A value corresponding to partial pressure of SO2 is obtd. as a function of temp, and pressure, and is multiplied by the reaction rate value to give a delignification rate value which is integrated over time to obtain a kappa number corresponding to the degree of cooking in the digester.

Filed: 1989-10-23
Granted: 1999-03-20
Abstract: A commercial message timer (114), when enabled by a user, stores data indicative of a first tuned station and begins timing a predetermined time period. Upon expiration of the time period, the first tuned station is automatically reselected if it had been deselected after the timer was enabled. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet have the receiver return automatically to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing PIX-IN-PIX circuity, the subject apparatus is responsive to an occurrence of (1) enabling the timer and (2) changing channels, in that order, for automatically moving the desired channel to the inset position. In response to the expiration of the timer period, the program displayed in the inset position is automatically returned to the main display position.

Patent KR-940008501-B1 (KR)
Title: Packaging machine
Inventor: KIM YONG-HWA
IPC: B65B9/00
Filed: 1990-12-04
Granted: 1994-09-22
Abstract: The packing machine consists of a frame (1) to fix resp. constitnents, a compression part (2) to seal the entrance of a pack by moving heater, properly heated, and compressing a sticking part (3) to discharge air in the pack before compression process, and a discharging part (4) to discharge the pack sealed. In this packing machine a charged pack is put into the device in an upright position, sealed by a heater body (24) fixed on a rod (21a) of a cylinder (21), and discharged by a discharging cylinder (42).
Patent KR-930011465-B1 (KR)
Title: Structure of multi-emitter transistor
Inventor: KIM YONG-CHAN
IPC: H01L29/73
Filed: 1990-12-14
Granted: 1993-12-08
Abstract: The multi-emitter transistor structure  is  characterized  by (a) forming a collector (15) on the fixed portion of an  epitaxial layer region (100) of the  semiconductor  substrate,  (b)  forming several emitters (11-14) arround the collector (15), (c) forming a base region (50), and (d) forming a base contact (16) on the fixed portion of the base region (50). The transistor structure improves a high level current characteristic  by  equalizing  the  interval between the collector and the emitters.
