Title: Control apparatus of sewing machine
Inventor: NEGI SHIGEO
IPC: H02P29/00
Filed: 1983-04-01
Granted: 1986-10-02
Abstract: A sewing machine control system comprises an adjuster for setting machine speeds, and a detector for converting the position of the adjuster into a digital set position signal which a converter converts into a speed setting signal for a sewing machine drive motor. The motor is step-by-step controlled in variable speed according to the value of the speed setting signal. A speed selected by the adjuster is maintained by a presetable timer so that the momentary changes in any speed setting signal selected by a position of the adjuster are ignored if the adjuster itself has not been position-changed.

Title: Semiconductor memory device
Inventor: ARIE SROB
IPC: G11C19/28
Filed: 1989-04-03
Granted: 1997-05-29
Abstract: In dynamic memories, generally a fluctuation of 10 % of the nominal value of the supply voltage is allowed. Since when reading, the input gate is applied to the supply, this fluctuation in the supply results in 20 % of fluctuation in the charge packet formed below the input gate. In order to eliminate this fluctuation and hence to increase the permitted interference margin for other interference sources, a voltage stabilization circuit is arranged between the source zone and the input gate so that the fluctuation in the supply also occurs at the source zone, as a result of which the size of the charge packet becomes independent of the supply. For the voltage stabilization circuit, use may advantageously be made of a band gap reference.

Inventor: MIN BYONG-MIN
IPC: H04N9/64
Filed: 1989-07-20
Granted: 1992-06-22
Abstract: The circuit includes an operation detector (3) for  detecting the operation status and digital video signals. A  speed  doubling converter (7) performs conversions by doubling  the  rate  of  the brightness signals which have been separated  from  video  signals and interpolated. A vertical  contour  compensating  circuit  (16) compensates the contour of the brightness signals in the  vertical direction in response to the  operation  detection  value  of  the operation detector (3). With the circuit, interpolated signals and original signals are speed-doubled, and then, the vertical contour is compensated by the operation status, with  the  result  that  a high quality picture is obtained.

Title: Method for continuous casting of molten steel and apparatus therefor
Inventor: YAMAMOTO HIRONORI
IPC: B22D11/115
Filed: 1991-03-22
Granted: 1995-03-29
Abstract: An apparatus for continuous casting of molten steel comprises a continuous casting mold (4); an electromagnetic stirring coil (7), which rotates and fluidizes molten steel inside the mold and which is installed outside the mold; and a screen (8) of ferromagnetic substance positioned between the mold and the electromagnetic stirring coil at a height including a level of meniscus. A method for continuous casting of molten steel comprises the steps of pouring molten steel into a contiuous casting mold (4); applying an electromagnetic force to the molten steel in the mold by means of an electromagnetic coil (7) installed outside the continuous casting mold; and shielding said electromagnetic force by means of a screen (8) of ferromagnetic substance installed between the mold and electromagnetic coil at a height including a level of meniscus. <IMAGE>
