Title: System for revolving processing picture data
Inventor: ISHIZU TAKAYUKI
IPC: G06T3/60
Filed: 1987-10-22
Abstract: PURPOSE:To prevent an unprocessed picture element or a picture element to be overlap-processed from being generated by selecting the plural numbers of straight line drawing means in a main scanning direction and executing a drawing. CONSTITUTION:Plural numbers of straight line drawing means 21-23 are provided in the main scanning direction.

Thus, after a revolving processing is executed, since the unprocessed picture element does not exist, the degradation of picture quality of the void of the image, etc., can be prevented. Since the picture element to be overlap-processed does not exist, the number of the processing picture elements is decreased and a processing speed can be improved. Then, even to an overlap processing to need a logical operation writing, there is no limit.
Patent JP-H08204515-A (JP)
Title: Radio receiver
Inventor: ANDORE GURUNIE
IPC: H03J5/02
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To shorten the station preselecting time of a radio receiver by constituting a preselection storing means so that the means may store the characteristic of a station having an electric field intensity exceeding a selection threshold. SOLUTION: A microcprocessor 7 is loaded with a program element, generates a digital value for selecting a receiving frequency in accordance with the element, and supplies the digital value to an element 2. When the reception level supplied to the program element from an A/D converter 6 at every step exceeds a count threshold during scanning, the content of a register is increased by one. When this occurs, it is profitable to increase the value of the next step to, for example, 0.3 MHz instead of 0.1 MHz. When each frequency step ends and the value of the reception level is obtained in the output of the converter 6, the program compares the output value with each count threshold and increases the counted result corresponding to the count thresholds exceeded by the reception level by one. Thus a highly reliable selection threshold is decided from the number of detected receptions.
