Patent KR-880000255-B1 (KR)
Title: Speech recognition microcomputer
Inventor: HITCHICOK MYRON H
IPC: G10L15/10
Filed: 1982-04-29
Granted: 1988-03-15
Abstract: The simplified, speaker independent, selected vocabulary, word recognising microcomputer functions without the use of a typical front end filtering network.  The microcomputer identifies vowel-like fricative-like, and silence signal states within a word or phrase by counting speech pattern zero crossings during sequential time periods.  Variable zero crossing count thresholds are used to identity states based upon previously identified states. Histeresis is provided, through the use of state time measurement to prevent the state oscillations which would result in erroneous state sequences.

Title: A process for preparing-chloroalanine
Inventor: OOOKA MASAHARU
IPC: C07C227/14
Filed: 1982-05-18
Granted: 1986-10-24
Abstract: Beta-chloroalanine was prepd. from aziridine-2-carbonate and HCl. Thus, 236 g of 32% aq. soln. of Na aziridine-2-carbonate was added to 168 g of 35% HCl, reacted 1 h at 40-45≰C, and chilled to -16≰C for 2h to yield beta-chloroalanine, which was filtered and washed with iso- Pro. The filtrate was reacted with 388 g of 10% NaOH soln. at 45≰C for 4 h to yield 105 g of 32% Na aziridine-2carbonate, which was reacted with 85 g of 35% HCl to give betachloroalanine. The total yield was 64% based on the initial aziridine-2-carbonate-Na salt.

Title: Movement monitor for card io-pulmonary and other activity
Inventor: DIAMOND DONALD A
IPC: A61B5/11
Filed: 1986-10-30
Granted: 1994-11-29
Abstract: A method and apparatus for monitoring means and for detecting motion in the vicinity of the apparatus, particularly a non-invasive cardio-­pulmonary activity, is disclosed comprising an electrostatic charge detector (10) for providing an output signal including signals indicative of motion, e.g. cardio-pulmonary activity of a person in the vicinity of the detector. A detection apparatus (Figure 2) is connected to receive the signals and to filter the extraneous noise signals from the signals of interest to provide output signals indicative only of the motion of interest of cardio-pulmonary activity of the person. Breathing signals are applied to a comparator (66) which is tripped if breathing occurs at a rate below a predetermined value. Cardiac signals are applied to a circuit which adjusts the trip level for the breathing rate if the cardiac rate declines to a level suggestive of brady-­cardia without breathing rate increases. The filtering circuit for the signal supplied by the charge detector incorporates a dual integrator (24) operating as a frequency selective charged amplifier which is effective to substan­tially eliminate all signals outside of the range of about 0.1 to 15 Hz.

Title: Process and device for controlling valve leakage spaces
Inventor: MIETH HANS O
IPC: F16K/
Filed: 1988-01-15
Granted: 1993-09-09
Abstract: The invention relates to a method for cleaning a valve sealing arrangement under dynamic stress, and an apparatus for carrying out said method, each sealing arrangement sealing two spaces from one another by means of two seals, separated from one another, in a serial arrangement, between or in which spaces there is arranged in a moveable manner a valve part whose jacket surface interacts with the seals and thereby prevents fluids overflowing from one space to the other, an annular space, enclosing the valve part, being provided between the seals, which annular space is bounded on the outside by a housing of the valve and which is connected via at least in each case one connection and one outlet opening to the environment of the valve. The invention ensures, inter alia, that even those critical regions of the slots for the seals which can be accessed only with difficulty are reliably subjected to the cleaning agent. In terms of the method, this is achieved, inter alia, in that the seal which comes into contact with the fluid to be sealed off is supplied with cleaning fluid from the spaces on both sides of the contact surfaces, up to its contact surfaces (provided temporarily at the sealing points) with the valve part on the one hand and the housing on the other hand. The apparatus for carrying out the method is characterised, inter alia, in that each seal (70, 71) is edged in each case on its side facing the space inside the valve housing part (1 or 2) to be sealed by a fluid-permeable boundary wall (41), and in that each of the seals has a limited mobility in the direction of movement of the valve part (4). <IMAGE>

Abstract: The circuit comprises an or gate  (15)  for  or-operating  on inputted address detection signal, a data latch or reset operating part (20) for latching and resetting  data  according  to  address detection signal, an  inverter  (11)  for  inverting  chip  select signal (CS1), a nand gate (14) for nand-operating output signal of the inverter (11) and chip select signal (CS2); a delay part  (19) for outputting the inverted signal by inverter (12) after delaying for a time; a nor gate (17) for nor-operating the  output  signals of data latch or reset operating part (20),  nand  gate  (14)  and inverter (12); and a nor gate (18) for  nor-operating  the  output signals of or gate (15) and nor gate (17) to give the last output. The circuit reduces power consumption and design area.

Title: Speed control system of motor
Inventor: MIN BYONG-HUN
IPC: G11B15/18
Filed: 1990-12-03
Granted: 1993-05-27
Abstract: The method  reduces  the  disturbance  like  the  oscillation caused by the distortion of the speed detector which  affects  the servo characteristic sensitively. The method comprises the  steps: (a) providing the minimum constant motor speed control signal when the count value for one period is less  than  the  preset  minimum control value; and (b) otherwise providing  the  maximum  constant motor speed control signal.

Abstract: The method is characterized by consisting of the following steps: (a) depositing a silicon nitride layer (11) on a supporting silicon substrate (12) to a fixed thickness and forming a region (13) for selective oxidation by etching the silicon nitride layer with photolithography and nitride layer etching, (b) forming a silicon oxide layer (13) by the selective oxidation of the region for a gas channel, removing the nitride layer and the selective oxide layer sequentially by using the selective oxide mask, and finally forming the gas channel (14). In this method, both selective oxidation and dry etching can be applied to make the gas channel.
