Abstract: The low frequency vibration washing machine includes a water basin(1), a disc(2) to induce a resonance in the multi-phase medium composed of water, detergent and air layers contained in the water basin(1), and a driving means(3) for the disc(2). The disc(2) is conical shape and has many protrusions(4) in shape of involute curve on the surface. These protrusions makes a flow of water by the vibrations of the disc(2) to turn the laundry. It prevents a jam of the laundry.

Title: Method of forming contact hole
Inventor: CHOI YANG KYU
IPC: H01L21/28
Filed: 1993-06-22
Granted: 2000-05-15
Abstract: PURPOSE: A method for forming a self-aligned contact hole is to selectively grow a metal layer on a conductive layer spacer formed on the sidewall of the conductive layer and then form a contact hole, by using the selective metal layer as a barrier layer pattern. CONSTITUTION: A first insulating layer(2) is formed on a lower conductive layer(1). A conductive interconnection is formed on the first insulating layer. The second insulating layer(5) and the conductive layer are deposited on the entire structure. A conductive layer spacer is formed on the sidewall of the second insulating layer by blanket dry etching. The conductive interconnection is overlapped with the first insulating layer by growing a selective metal layer(14) on the conductive layer spacer. The third insulating layer(8) is formed on the entire structure. A contact hole(10) is formed to expose the lower conductive layer by etching the third insulating layer, the second insulating, and the first insulating in this order.

Abstract: The multiplexor(4) inputs a lot of analog signal selectively according to selective signal, and the analog/digital converter(3) transforms the analog which impressed from the multiplexor into the digital data. The demultiplexor(2) outputs the digital data which impressed from the analog/digital converter to the input terminal of the microprocessor according to selective signal. The microprocessor outputs the selective signal to the multiplexor and demultiplexor, and makes them interlock. Therefore, the structure of unit is simplified and the manufacturing cost is reduced.

Title: 1-ñô-methyl-carbapenem derivatives and their process for preparing them
Inventor: KIM YOUNG-SOOK
IPC: C07D487/04
Filed: 1993-12-07
Granted: 1997-04-15
Abstract: The invention is related to new carbaphenem derivatives for preparing of 1-.beta.-methyl-carbaphenem derivatives as a intermediate of carbaphenem compound which has excellent and strong antiviral activity. The derivatives may be prepared by the method using Collin's reagent, the method using Corey's reagent, PDC method, PCC method and Swern oxidation method. According to Swern method, the derivatives are prepared in more than 85% yield.
