This pressure difference works on the electro viscosity fluid(80) in the storage(70) thru the connecting holes(45)(55)(65). Therefore the electro viscosity fluid(80) is provided to the space part(90) thru the injection part(62). In case the print signal is provided to the 1st and 2nd electrodes(41)(61), the viscosity of the electro viscosity fluid changes in accordance with the potential and by the difference of the viscosity pressure, the amount of the ejection of the fluid(80) is determined. The fluid(80) is ejected thru the ejector(35) and records a picture on the paper.

Title: Input signal transition detector
Inventor: LEE JAE-JIN
IPC: G11C11/407
Filed: 1993-09-17
Granted: 1996-10-04
Abstract: The detector reduces the volume and the area by designing the circuit in which the input signal transition states(high/low) use the same delay circuit. The detector comprises: a delay circuit(20) for generating the delayed input signal(ADD); a PMOS transistor(MP21) for playing a resistor component between the output device(ATD) and the power volume; two NMOS transistors(MN21, MN22) connected to a common drain(CC) of the PMOS transistors(MP22, MP23) and controlled by the output signal(DADD) from the delay circuit(20) and the input signal(ADD).

Title: Ion implanting method
Inventor: JOO SEUNG-KI
IPC: H01L21/22
Filed: 1993-10-14
Granted: 1996-10-23
Abstract: depositing a Co metal in order that a silicon substrate may obtain some resistance in a vacuum evaporator; implanting diffusion ion by controlling the ion implantation energy in order that the projected range(Rp) of the Co metal may be in the metal thin film; a first rapid thermal processing to form a silicide and a junction at a temperature of 700 deg.C for 30 sec in the atmosphere of nitrogen; and removing the impurities not reacted in the junction after the first thermal processing.
Patent KR-100278213-B1 (KR)
IPC: B29C45/00
Filed: 1993-11-04
Granted: 2001-01-15
Abstract: A method of making a plurality of optical record disc substrates, comprising: injecting a resin material into a plurality of disc-shaped cavities which are formed by closing a fixed mold half and a movable mold half; and cooling the injected resin material in the cavities; wherein the cavities are grouped into a plurality of groups so that each group includes not less than one cavity, and each group is provided with a common actuation means so that each actuation means is independently operated. <IMAGE>
