Granted: 1993-10-08
Abstract: The optical head brings the minimization of size,  inhibition of changing of properties according to temperature variation,  and reduction of vibration generated from the shape of support members or material properties. The optical head for  reading  information in the disk by tracking and focusing of an object lens,  comprises a magnetic force generating means having permanent magnet (15)  or an electromagnet (150) on board (10) to control  the  position  of holder (12) loading object lens (13); magnetic pole  section  (14) mounted on the holder (12) and  being  opposite  to  the  magnetic force generating means. When the magnetic force  generating  means is electromagnet (150), the section (14) has a sharp-edge shape in center.

Title: Molding method and apparatus for liquid vessel cap
Inventor: KIM SONG-NAM
IPC: B29C45/26
Filed: 1991-10-25
Granted: 1995-01-11
Abstract: The liquid container cap is made of low density polyethylene resin by injection molding. The circular protrusion formed at the under cut of cap is molded by one set process of cap injection molding and can be mass produced. By placing the connection piece which connects the cap body and cap lid at the outer center of cap body, the perfect sealing effectiveness can be achieved and also the cap can be shut and opened by one touch. The circular protrusion-forming core is devised between upper cavity plate and support plate with core spring.

Title: Input wave generator
Inventor: SHIM TAE-HYON
IPC: H03L7/00
Filed: 1991-12-28
Granted: 1994-04-02
Abstract: The generated comprises the following means; on inverter (I1) which outputs the inverted bi-phase signal (BPD) coming from transmission line (30); a first edge signal detector (10) outputting the falling edge of the BPD signal; an OR gate (O1) outputting the logic add signal of the first and second edge signal detectors; a nand gate (NA1) outputting the inverted logic multiplication of the two inputs, one from the OR gate output and the other from a clock signal of a period.
