IPC: G03F7/023
Filed: 1992-06-26
Granted: 1995-06-07
Abstract: The quinone diazide positive resist compsn. for i-rays is composed of a novolak resin (A) having 3,000-30,000 average molecular wt., and 10-15 wt.% of a 2,3,4,4-tetrahydroxy benzophenone-1,2-naphthoquinone diazide sulfonic acid ester (B) w.r.t. the resin (A). The positive resist compsn. is produced by reacting 1,2- naphthoquinone diazide-5-sulfonyl chloride and 2,3,4,4'- tetrahydroxy benzophenone in the presence of triethyl amine catalyst. The resist compsn. gives a good pattern profile in the i-rays on the base of a superior solution-inhibiting effect.

Granted: 1993-01-11
Abstract: This invention relates to certain polypeptides found to be present in the venom of the Agelenopsis aperta spider. The polypeptides block calcium channels in cells of various organisms and are useful in blocking said calcium channels in cells, per se, in the treatment of calcium channel mediated diseases and conditions and in the control of invertebrate pests.

Title: Digital nyquist filter
Inventor: JONG YU-JIN
IPC: H03H17/00
Filed: 1992-12-31
Granted: 1995-03-10
Abstract: The digital nyquist filter makes easy a circuit design, and improves operational stability and its productivity. The filter includes a D type counter (10) which delays the input data (Din), a ROM (20) which processes the impulse responce, a buffer (30) which temporarily stores the filtered wave, a divider (40) which processes the impulse sampling, a delay line (50) which compensates the time delay, a digital/analog converter (60) which converts buffer data into the analog data, a low pass filter (70) which removes the unneccessary frequency component.
