Provided are a conductive composition for thin film printing and a method for forming a thin film conductive pattern, which can easily performing thin film printing, and can capable of improve conductivity by thermal sintering at a comparatively low temperature of 300&#xb0; C. or less or by photo irradiation. A conductive composition comprises metal particles, a binder resin, and a solvent, the content of an organic compound in the solvent being 5 to 98% by mass, the organic compound comprising a hydrocarbon group having a bridged cyclic structure and a hydroxyl group, the content of metal particles being 15 to 60% by mass, the metal particles containing 20% by mass or more of flat metal particles, the content of the binder resin being 0.5 to 10 parts by mass relative to 100 parts by mass of the metal particles, and the viscosity at 25&#xb0; C. being 1.0&#xd7;10to 2&#xd7;10mPa&#xb7;s. The composition is printed in a pattern having any selected shape on a substrate, by screen printing, and the pattern is subjected to thermal sintering at a temperature of 300&#xb0; C. or less and/or subjecting the pattern to pulsed light irradiation.

A miniaturized inexpensive vibration generator using rotary bodies having unbalanced weights with no absolute encoders provided on the rotary body driving means. Rotary bodies having unbalanced weights are disposed in an opposed state. Members to be detected are fixed to the rotary bodies so that the members to be detected have a predetermined positional relation with the relative weights and rotation detectors are provided fixedly in the positions close to the loci of the rotational movements of the members to be detected, and adapted to output signals representative of what are detected thereby in the form of pulses each of which is generated every time each of the members to be detected passes the relative rotation detector, i.e., every time each member to be detected is revolved 360.degree., a phase difference computing element computes a phase difference between the unbalanced weights on the basis of the signals from the rotation detectors.
