Title: Dry etching method
Inventor: MATSUZAKI KAZUO
IPC: H01L21/302
Filed: 1984-03-13
Abstract: PURPOSE:To enable to bring the shape of etching cross-section of an insulating film into an arbitrarily and easily controllable state using a cylindrical plasma etching device by a method wherein the amount of side etching given to the film to be etched is controlled by the partial voltage ratio of the inert gas for reaction gas. CONSTITUTION:When a microscopic work is going to be performed on the insulating film consisting of a poly silicon film, a silicon nitride film, a silicon nitride film and the like using a cylindrical plasma etching device, the partial voltage ratio of dilute gas with Freon gas is brought to 1 or above by performing an etching wherein dilute gas is mixed to Freon gas, for example, if said insulating film is to be formed in the vertical cross-sectional form same as the size of photoresist coated on the insulating film. Also, when an inclination is given to the cross-sectional form of the insulating film for the purpose of preventing generation of an unsatisfactory step coverage, a plasma etching is performed in the state wherein the partial voltage ratio is brought to 1 or below. Through the above-mentioned procedures, the cross-sectional form after etching performed on the insulating film can be determined arbitrarily.

Title: Radar
Inventor: KIUCHI HIDEKAZU
IPC: G01S7/36
Filed: 1990-02-27
Abstract: PURPOSE:To suppress a stable jamming wave by arranging a radar antenna, a radar receiver, a Side Lobe Canceler (SLC), an SLC receiver, an SLC processor, a jamming wave detector and the like. CONSTITUTION:A microwave signal received with a radar antenna 100 is detected with a radar receiver 200 and microwave signals received with SLC antennas 100-10N are detected with a selector 800. Both the received signals detected undergo a side lobe cancel processing with an SLC processor 500. Jamming waves coming from a side lobe direction of the antenna 100 is received at almost the same level with both the antennas, indicating the same phase changing characteristic and spreads in a distance direction equivalent to a pulse width and hence, it is suppressed effectively by the side lobe cancel processing. A jamming wave detector 600 calculates the direction of arrival of the jamming wave from the change characteristic according to the bearing direction in a level of the jamming signal received with the antenna 100 and reports to a selector 700. The selector 700 makes a selection of incoming orientation between automatic and manual jamming wave to send a selection signal to a selector 800.

Title: Image encoding device
Inventor: KIMURA TSUKASA
IPC: H04N19/00
Filed: 1995-03-08
Abstract: PURPOSE: To provide an image encoding device which can decrease the amount of information after encoding while suppressing the deterioration of an important image part in a frame. CONSTITUTION: Before an image is encoded and compressed, the important image part is extracted manually through visual confirmation or according to the size of a moving vector between frames to determine other parts as an area where information is deleted, pixel by pixel, by an information deleted area determination part 103. In this information deleted area, an information deletion amount setting part 104 sets the weight of smoothing by the pixels in the information deleted area according to the distance from the important image part. An information deleting process part 105 performs a smoothing process for replacement with the signal values of pixels by adding the set weight to the signal values of the pixels and the signal values of peripheral pixels in the same frame and making them uniform.  Consequently, the amount of information after encoding is reduced while deterioration of the important image part in the frame of an image, outputted from an output part 128, owing to band limitation is suppressed.
