Title: Exposure apparatus and method of aligning exposure mask with workpiece
Inventor: OSITA YOSITADA
IPC: G03F9/00
Filed: 1984-12-26
Granted: 1990-03-05
Abstract: The apparatus includes a plate mask (1), an alignment/reflection area section (30), a movable stage (7) for holding a workpiece (2) with an alignment mask (22), a light source (4) and a projection lens (3). An alignment arrangement detects the positional relationship between the alignment mask portion and the workpiece alignment mark, and produces an alignment control signal.  The alignment arrangement includes a second light source (503) to illuminate the workpiece alignment mark so that the light from the mask is directed to the alignment area section and then reflected at the alignmnet arrangement's reflection portion to provide an image on the workpiece alignment mark. A device (5) detects the reflection image and an image of the alignment mark.

Title: Dynamic equalizing control circuit for magnetic recording device
Inventor: YUN JONG-YUN
IPC: G11B5/035
Filed: 1991-11-25
Granted: 1994-05-25
Abstract: The circuit is for reducing the peak shift of the read data caused by interference. The circuit includes a track information generator, a controller for providing the boost signal for equalization control after converting the read track information to an analog signal, and a circuit for controlling the pulse sensor with the boost control signal to reduce the peak shift of the neighboring bit information.

Title: Poly ether ester block copolymer resin composition
Inventor: KIM KYONG-MIN
IPC: C08L67/02
Filed: 1991-12-30
Granted: 1995-08-09
Abstract: The copolymer composition enhances working properties such as melt strength. The copolymer comprises A)60-00wt.% of polyether ester copolymer which is polymerized of polyetherester block copolymer composed of hard segment of formula(I) and segment of (II), and a crosslinking agent; and B)polyether ester block copolymer resin with 1-40wt.% of ethylene/propylene compd. The above cross linking agent contains prim. or sec. amine compd. essentially, and is selected from dimethylamine, diethylamine, hexamethylene bis(aminoacetic acid), trypsin, D or D,L-serin, D,L-treonin hemihydrate, D,L-aspaltic acid, 2-aminoadipic acid, and tris(hydroxymethyl)aminomethane.
