A coordinate reading device including magnetostrictive vibration transmission media to attain coordinate readings of analog figures. A fixed magnetizing coil is wound about or placed on the surface of the media to automatically magnetize the media. A preparatory exciting system excites the exciting coil of the media before an effective excitation pulse is applied to the coil by suitable delay circuits.

A magnetic field sensor housed in a cooling device has an inner core body for measuring the behavior of a charge put in a shaft furnace, an inner casing for accommodating the inner core body therein, and an outer casing for accommodating the inner casing with a space for a circulating path of cooling medium therebetween. The inner core body consists of an exciter for exciting the charge put in the furnace, a magnetic field sensing member arranged in front of the exciter for detecting the exciting magnetic field generated from the exciter and a driving circuit arranged at the rear of the exciter for driving the sensing member.

Continuous soldering of small elements along a line is achieved by a radiant beam spot lamp which moves intermittently along the line, and radiant energy is supplied only while the lamp is stopped to form partially overlapped heating zones.

Method of continuously soldering small elements arranged generally in a

The orthogonal flux gate thin film magnetometer comprising an orthogonal flux gate utilizing a rotation magnetization mechanism consisting of a sensing coil wound on a plated wire formed by applying to a conductor a ferromagnetic thin film, an alternating excitation power means for exciting the thin film of the flux gate, an amplitude difference detection circuit means for detecting a difference between positive and negative asymmetrical peak values of the output voltage of the flux gate, and a control means for feedback of the output of the detection circuit to the sensing coil of the flux gate through a feedback circuit and for supplying the output of the control means to an indicating means. The magnitude and the polarity of the external magnetic field are sensed from the feedback current which erases the external magnetic field applied to the flux gate.
