Abstract: According to one embodiment, a magnetic memory device includes an electrode, and a magnetoresistance effect element provided on the electrode. The electrode includes a first electrode portion and a second electrode portion provided between the magnetoresistance effect element and the first electrode portion and containing a metal element selected from molybdenum (Mo) and ruthenium (Ru).

Abstract: In an optical current transformer, an optical sensor is made up of two optical sensor units which are independent of each other. Incident light beams are applied to the optical sensor units, and the emergent light beams from the latter are subjected to addition, to obtain a measurement signal which is proportional to a current under test which flows in a conductor. The optical sensor units are substantially U-shaped bars, which are Faraday effect glass bars which are rectangular in cross section and have 45.degree. reflecting surfaces at the corners.

Abstract: A television receiver includes a vertically oblon CRT having an aspect ratio of about 3:4, and a first and a second display part each having an aspect ratio of about 4:3 are formed together with a third display part (a status display part) in the display area of the CRT, so that a picture-in-picture display, a teletext display, etc. can be simultaneously produced on the first and second display parts together with a status display on the third display part without cutting out part of the displayed video information.

Abstract: It is an object of the present invention to provide a method of controlling the automatic transmission of a vehicle, in which the vehicle can be smoothly started on a low frictional coefficient road by requiring the concurrent operation of the brake pedal and the acceleration pedal. An up-shift operation will occur when both the brake and acceleration pedals are operated when the vehicle speed is less than a predetermined value.

Abstract: A light signal reading method in which a first light beam modulated to a polarized state in accordance with information magnetically recorded on a recording medium is caused to interfere with a second light beam of a frequency different from that of the first light beam, and the information being detected as a variation in the intensity of the interference light, and an apparatus therefor.

Abstract: A video amplifier is disclosed wherein the luminance signal is applied to the collector circuit of a differential amplifier comprising two transistors, the color difference signal is applied to the base of one of the two transistors, and the primary color signal is derived across a load resistor coupled to the collector circuit.
