Abstract: The muffler for preventing the accumulation of the oil in the concave section and the resonance box, has an oil receiving hole respectively connected with the concave section and the resonance box. The muffler comprises a cylinder having an inlet and an outlet; a resonance hole connected with the resonance box and formed near the inlet of suction flow passage; a concave hole connected with the concave section and formed near the other side of the suction flow passage; an oil receiving hole formed at the lower side of the resonance hole and the concave hole.

Title: Interfacing circuit for image data
Inventor: KIM DONG-KYONG
IPC: G06F3/153
Filed: 1992-12-08
Granted: 1995-02-27
Abstract: The circuit is used for interface between CPU and a processor board for image compression and decompression. The interface circuit translates the TARGA or MMP data type to represent the true color image, into a data type for the compression board. The first interface module (21) converts the image data (D0-D5) into the pixel data (VD0-VD23). The second interface module (22) outputs the image data generated by converting the pixel data based on an external control signal (TARMD), data type, pixel enable signal (PIXOE0-PIXOE2), and a control signal.

Title: Method of compensating for overlaying error in semiconductor device
Inventor: MOON SEUNG-CHAN
IPC: G03F7/26
Filed: 1992-12-17
Granted: 1996-06-07
Abstract: The method for correcting overlaid error in fabrication of a semiconductor device includes the steps of forming at least two marks for measuring box-in-box type overlay accuracy measuring masks on a predetermined scribe line placed in the peripheral region of a semiconductor chip, measuring how the masks are deviated from their cores to obtain overlaid error values in X and Y directions, and using the average value of the overlaid error values as a correction value for the overlaid error between patterns.
