Patent KR-970001656-B1 (KR)
Title: Controlled absorption diltiazem formulations
Inventor: GEOGHEGAN EDWARD JAMES
IPC: A61K31/352
Filed: 1988-10-17
Granted: 1997-02-13
Abstract: A controlled absorption diltiazem pellet formulation for oral administration comprises a core of diltiazem or a pharmaceutically acceptable salt thereof in association with an organic acid, and a multi-layer membrane surrounding the core and containing a major proportion of a pharmaceutically acceptable film-forming, water insoluble synthetic polymer and optionally a minor proportion of a pharmaceutically acceptable film-forming, water soluble synthetic polymer. The number of layers in the membrane and the ratio of the water soluble to water insoluble polymer, when said water soluble polymer is present, being effective to permit release of diltiazem from the pellet at a rate allowing controlled absorption thereof over not less than a twelve hour period following oral administration. The pellet has a dissolution rate in vitro which when measured in a dissolution apparatus (paddle) according to U.S. Pharmacopoeia XXI in 0.05 M KCl at pH 7.0 results in not more than 35% of the total diltiazem being released after 2 hours of measurement. Not more than 60% of the total diltiazem is released after four hours of measurement and 100% of the diltiazem is released no earlier than after 8 hours of measurement in said apparatus.

Abstract: The method involves selecting first latch  data  as  a  phase error signal for control of the phase of the capstan motor  in  an interval of -π to π of  the  phase  of  the  capstan  motor.  In intervals - 2π to -π and   to 2π of the phase of the capstan motor, second latch data is multiplied by two and is  then  of  the  same polarity as that of the first latch data. The  second  latch  data multiplied by two is added to the first latch data. In result, the added value is selected as the phase error signal. Also, a portion of the data above double the upper  limit  value  is  cut  in  the interval of -2π to -π and a portion of the data below  double  the lower limit value is cut in the interval of π to 2π.

Title: Method of detecting playback signal of optical pickup
Inventor: KIM YEONG UNG
IPC: G11B7/005
Filed: 1992-04-30
Granted: 2001-06-01
Abstract: PURPOSE: A method of detecting a playback signal of an optical pickup is provided to use an optical detector that is multi-splitted to track directions of information, and to differentiate signals output from two areas of the multi-splitted optical detector by a differential amplifier, so as to read written information with a double recording density. CONSTITUTION: A beam generated from a laser diode(1) is converted into a parallel optical beam by a collimating lens(2). A monitor optical detector(4) detects portions of the beam by a beam splitter(3). The beam splitter(3) reflects portions of the rest of the beam. The portions of the rest beam are focused to an optical disk(6) via an objective lens(5). Portions of an optical beam reflected from the optical disk(6) are reflected in the beam splitter(3) to return to the laser diode(1). Portions of the rest optical beam go straight to the beam splitter(3) to pass a focus lens(7) for detecting a focus signal and a cylinder-type lens(8). The portions of the rest optical beam are splitted into two beams by the beam splitter(9). One of the beams is detected by a 2-splitting optical detector(10) for detecting a focus signal. The other beam is detected by a 2-splitting optical detector(12) for detecting a read signal.

Title: Alumina coated sintered body
Inventor: LJUNGBERG BJOERN
IPC: C23C8/06
Filed: 1992-06-25
Granted: 1999-06-15
Abstract: According to the invention there is now provided a sintered hard material body at least partly coated with at least one 0.5-20  mu m wear resistant ceramic oxide coating being <80% thicker in the edges than on the flat surfaces. The oxide coating exhibits a grain size ( DIAMETER ) in  mu m for which: <MATH> where x is coating thickness in  mu m on at least 80% of the flat surfaces of the body,     k = 0.5, preferably 0.3 and     1 = 2  mu m for 4</=x<20 and 1=0 for 0.5<x<4. The oxide coating is achieved by using a deposition process in which the body is in contact with a gas containing one or more halides of a metal or metals and a hydrolysing and/or oxidizing agent forming the metal oxides and with an additional reactant (dopant) of sulphur, phosphorus, selenium, tellurium, arsenic, antimony and/or bismuth and/or compounds thereof. The temperature during deposition is in the range of 800-1000 DEG C, preferably 850-970 DEG C, and the volume concentration of the additional reactant is 0.25-3, preferably 0.3-1 % of the total gas volume.

Title: Nand type mask read only memory
Inventor: MOON HEE-MAN
IPC: H01L21/8229
Filed: 1992-10-29
Granted: 1996-04-26
Abstract: The nand type mask read only memory comprises a first depletion type string selection transistor and a second enhancement type string selection transistor which are connected to bit line in series, and a number of cell transistors connected in series between the selection transistor and ground voltage terminal. The channel length of the enhancement type string selection transistor is longer than that of the depletion type string selection transistor. The higher integration of mask ROM is realized.
