Abstract: Disclosed herein is a magnetic head wear-rate measuring apparatus for measuring the rate of head wear in noncontact form and with high accuracy. A magnetic sensor is disposed so as to be opposed to a magnetic head and serves as a part of oscillating elements of an oscillator circuit. A magnetic resistance of a magnetic circuit at a rotational position where the magnetic head faces the magnetic sensor, changes according to the degree of extension of the magnetic head from the surface of a drum, and the change in magnetic resistance acts as a variation in oscillating frequency. The change in frequency is converted into a counter output. A counter is supplied with a pulse Pd of a measured oscillating frequency and correspondingly produces a pulse (counter output) Px having a pulse width up to the counting of a predetermined number of pulses. Thereafter, the counter output Px is supplied to a second counter where the number of reference clocks lying within the pulse width is counted.

Abstract: A component mounting apparatus has an ultrasonic vibration generating apparatus which supplies ultrasonic vibration making a lead-free solder with no lead which is provided between an electronic component and a circuit board melted to the electronic component. The lead-free solder is melted by the ultrasonic vibration and then connects the electronic component on the circuit board. Accordingly, the ultrasonic vibration generating apparatus can heat only the lead-free solder partially, the electronic component and the circuit board can be joined without applying thermal influence to a whole of the electronic component and circuit board.

Abstract: A board positioning method includes the steps of selecting one of a plurality of positioning sections or stations for positioning a particular type of board located in a specified position. The method allows positioning different types of boards in specified positional relationships by locating only a positioning section corresponding to the board to be positioned, so that the positioning section faces the board located in the specified position. The positioning section is moved into the specified location by means of a support member. Thereby, positioning various types of the boards in a specified common position is possible without the need to make adjustments to a single positioning station.

Abstract: A corrosion degree measuring method capable of field measurement for intergranular corrosion, particularly the sensitization degree, of the plant's structural materials in a narrow space. The metal electrode made of a material being measured and the counter electrode to the metal electrode are immersed in an electrolytic solution. A voltage is applied to the metal electrode in the anodic direction so as to raise the potential of the metal electrode up to the passive state potential and to keep the metal electrode at the passive state potential. The passive state potential is used as a reference potential, and a pulse-like potential signal is applied to the metal electrode in the cathodic direction. At the time of the application of the pulse potential signal, a current between the metal electrode and the counter electrode is measured, and the corrosion degree of the material being measured is determined from the intensity of the current.
