Abstract: This invention relates to a method for automatic control of a microwave oven which can make precise cooking control available by classifying the cooking control into cases when cooking is completed below the boiling point of water, such as thawing or warming up, and cases when cooking is completed above the boiling point of water. For types of cooking which are complete without water boiling, the invention sets the initial cooking time period by determining the time it takes for the output voltage of a temperature detection sensor to reach a rise starting point. For types of cooking which include water boiling, the invention sets the initial cooking time period by determining the time it takes for the output voltage of the temperature detection sensor to reach a maximum rise point. The invention then sets an additional time period equivalent to the initial time period multiplied by a cooking constant corresponding to the type of cooking that is desired.

Abstract: In-line type electron guns for a color picture tube. In this electron guns, the third electrode or the G.sub.3 electrode is divided into two focusing electrodes, that is, first and second focusing electrodes. The envelop of the first focusing electrode has at its front end a control electrode plate provided with at least three rectangular openings, the vertical size of each the rectangular opening being larger than the horizontal size. An electrode body for electrostatic control of the three electron beams is recessed in the electrode envelop of the G.sub.4 electrode.
