Granted: 1986-11-01
Abstract: 1,4-Dihydropyridines. [(±)-I! and their salts were prepd. Thus, 4.98 g VII(R1=CH3), 6.05 g IX (R2=benzylpiperidyl), and 1.76g of 29% ammonia soln. were added into 20 ml EtOH and stirred 12 h under reflux. The reaction mixt. was added to 50 ml H2O. The mixt. was extracted with 60 ml ethylacetate. 10ml of 4N HCl was added in the organic layer and agitated 1 h. The organic layer was washed with 20ml saline and later with 10 ml water. The mixt. was dried on anhydr. NaS and vacuum-concd. The concentrates were mixed with a soln. of chloroform and acetone(1:9 v/v) to give 3.02 g (±)-I.HCl. Compds. (±)-I have a hypotensive effect.

Abstract: It is already known in the art to connect a network consisting of a capacitor, a resistor and a diode to a transformer (Tr) to limit voltage peaks. The aim of the invention is to decrease the relatively high losses of about 10 % in the resistor. This network is replaced by a capacitor (C2), and located on the secondary-winding side, in parallel with the diode (D1) which generates the operating voltage, is a switch (T2) which, when the charging current (iD) for the charging capacitor (C1) has decayed away, generates a current (iT2) from the charging capacitor (C1) back to the secondary winding (2). Particular applications of the circuit of the invention are in television receivers and video recorders.

Abstract: 본 발명은 디지탈 데이타의 동기 신호 제어에 관한 것으로, 일반적으로 사용되고 있는 디지탈 데이타 재생회로는 유효 데이타와 더미 데이타의 동기 블록을 판별하기 위한 서로 상이한 형태의 동기 블록을 형성하므로 기록 포맷을 맞추기 위한 회로가 복잡해지고, 재생시에도 유효 데이타 블록과 더미 데이타 블록을 판별하기 위한 회로가 부가되므로 복잡한 회로가 필요하게 되는 문제점이 있다. 
     이에 따라 본 발명의 목적은 상기와 같은 종래의 디지탈 데이타의 동기신호 제어회로에 따른 결함을 해결하기 위하여, 재생시 검출되는 동기신호중 동기신호를 계수하여 더미 데이타 동기 블록의 동기신호를 억제하고 유효 데이타 동기 블록만을 추출하는 동기신호 검출회로를 제공하는데 있다.

Title: Oil supply device of inside stern tube of contrarotating propeller for ship
Inventor: CHOE TAE-SAM
IPC: B63H21/38
Filed: 1992-10-02
Granted: 1995-10-06
Abstract: A lubricant distribution box (10) is installed between a flange (50) of outer propeller shaft and the other flange of outer middle shaft (60) in a double contra-rotating ship propeller. A rear seal (30) of the inner stern shaft (90) is connected to inside connections (103) of the lubricant distribution box by lubricant conduits (40) installed between the inner stern shaft and the outer propeller shaft. A front seal (20) of the inner stern shaft is fixed by fastening screws (203). A ring-shaped cover (10-1) connecting the inlet and outlet conduits is fixed around the periphery of the lubricant distribution box in which a lot of connections (103) are formed in a stepped cylindrical shape.

Title: Washing machine with a ozone-injection device in the tub
Inventor: IM HUI-TAE
IPC: D06F17/12
Filed: 1992-10-07
Granted: 1995-11-24
Abstract: an ozone generating unit for generating ozone; an ozone path tube for ejecting the ozone generated from the ozone generating unit; an ozone ejecting hole connected with an air path tube in a side of the ozone path tube; and a unit for generating bubble in a washing machine. An orifice is formed in one side of the air path tube.

Title: Ignition and extinguish time control method
Inventor: ADACHI IKURO
IPC: F24H1/10
Filed: 1992-10-31
Granted: 1995-10-14
Abstract: When the differential temp. between water supply temp.(ΔT) and setting temp.(T0). is small under the condition hot water is supplied near an ignition flow rate(Q2) and if the water supply temp.(T0) detected by a noise sensor(11) is slightly changed, an extinction flow rate(Q1) will be markedly fluctuated so that a gas burner(15) may be forcibly put out. However, under the condition as described above, a specified computation must be made to increase a differential(Q0), thereby increasing the differential between the ignition flow rate(Q2) and extinction flow rate(Q1). This increased differential serves to prevent the generation of a troublesome chattering phenomenon that the gas burner(15) repeats a series of ignition and extinction at a short interval. When the differential temp.(ΔT) approaches or when the water supply temp. and the setting temp. approach each other relatively, the differential(Q0) will be increased.

Title: Common memory access device
Inventor: CHOE KWANG-JIN
IPC: G11C7/00
Filed: 1992-12-29
Granted: 1995-04-12
Abstract: To block the data collision at accessing the data from two processors, the common memory access device utilized the time difference of the half-clock period between two enable signals. To do this, the device consists of two processors to access the common memory, a common memory to communicate with the processors, an address multiplexer to select the address buses of the processors, and an enable signal generator to supply two enable signals with the time difference of the half-clock period.

Title: Process for preparing silica coated gamma ferrite
Inventor: LEE JAE-YOUNG
IPC: C01G49/02
Filed: 1992-12-30
Granted: 1996-01-15
Abstract: The silica coated gamma-ferrite is prepared by (A) forming iron hydroxide through the solution reaction of aqueous alkaline-added iron salt solution with air, (B) cleaning formed iron hydroxide more than 3 times with water 2 times the amount of the solution, (C) controlling the pH of the iron hydroxide slurry of 6-9.0 and the concentration of the slurry at higher than 2M, (D) pretreating the iron hydroxide slurry by agitating and dispersing for more than 1 hour for silica coating, and (E) coating iron hydroxide with a coating material containing 0.1-1.0 wt% silica with respect to the weight of iron hydroxide, followed by heat-treating the silica coated iron hydroxide.
