Patent KR-900001812-B1 (KR)
Title: Short-protected buffer circuit
Inventor: MASARU FUKUTA
IPC: H03K19/003
Filed: 1984-02-04
Granted: 1990-03-24
Abstract: The circuit includes a constant current source, a source current OP transistor and a sink current OP transistor.  The transistor is protected from excessive current by voltage reference transistors and series-connected FETs, which form a currentlimiting by-pass circuit. The circuit limits the gate voltage on the transistor and so limits the output source current.  However, the limiting action begins at a much lower output voltage than in conventional circuits.  That voltage can be changed by changing the voltage reference supplied to the gate of the transistor by changing the gate length and width of transistor.

Title: Process for craze-resistant polymodal liner block copolymer with terminal tapered blocks
Inventor: SZALLA FRANK J
IPC: C08F297/04
Filed: 1987-03-20
Granted: 1993-04-15
Abstract: Sequential charging of initiator and monomers in a multistage solution polymerization process involving conjugated diene and monovinylaromatic monomers wherein the final charge is a mixture of these monomers results in the production of resinous polymodal linear block copolymers each with a terminal tapered block. A typical 5-stage charge sequence is as follows: Stage 1: (Si); Stage 2: (Si); Stage 3: (B); Stage 4: (Si); Stage 5: (S+B) wherein (Si) is monovinylaromatic monomer and initiator; (B) is conjugated diene monomer and (S+B) is monovinylaromatic monomer and conjugated diene monomer. At each stage, polymerization is allowed to continue until no free monomer is present. The trimodal block copolymer products comprise high, medium and low molecular weight species designated, respectively, as S1-S2-B1-S3-B2->S4; S2-B1-S3-B2->S4; and S3-B2->S4 wherein S1, S2 and S3 represent, respectively, polyvinylaromatic blocks resulting from polymerization of the first, second and third charges of monovinylaromatic monomer (stages 1,2 and 4); B1 represents a polydiene block resulting from polymerization of the first charge of conjugated diene monomer (stage 3); and B2->S4 represents a terminal tapered copolymer block resulting from polymerization of the conjugated diene and monovinylaromatic monomers (stage 5). The subject copolymers can be fabricated into sheets and molded objects possessing little color, a high degree of transparency and excellent impact resistance. These fabricated products do not craze on being impacted.

An outputting unit(10), a decoder(11), a logic determination unit(20) and a key board are respectively connected to the microcomputer(7). The apparatus further includes a distance sensing unit(15) for sensing the distance between the color sensing unit(1) and the object, and a signal transmission unit(19) for sending the output signal from the distance sensing unit(15) to a logic determination unit(12).

Patent KR-930008854-B1 (KR)
Title: Clipless pedestal of wafer
Inventor: LEE YONG-U
IPC: H01L21/30
Filed: 1991-04-30
Granted: 1993-09-16
Abstract: The clipless pedestal for  dry-etching  oxide  films  removes clips on the pedestal of the prior art to improve the pedestal. In the pedestal having a plurality of pedestal rings  for  insulating the first face of the pedestal, an  insulation  elastormer  placed over the second face for contacting with a wafer,  the  upper  and lower clips between the rings and the elastomer and  a  set  screw and a wafer button for securely holding the wafer, the  upper  and lower clips are removed to replaced  by  the  improvement  of  the rings and the insulation  elastomer  on  the  inner  side  of  the pedestal is replaced with a kapton tape.
