    摘要： An information recording and reproduction apparatus for a magneto-optical medium includes a synchronizing signal generation circuit for generating a synchronizing signal to provide a pulsed laser beam at the time of reproduction according to an internal clock obtained from a reproduction signal. The laser beam is driven on/off according to the synchronizing signal at the time of reproduction to have the laser spot on the signal plane prevented from being enlarged, so that the reproducible domain is smaller than the domain of when a laser beam is continuously emitted. In reproduction, an optical superresolution method is applied simultaneous to provision of a pulsed laser beam to allow reproduction of higher density. An external synchronizing signal generation circuit for generating an external synchronizing signal according to a wobble on a surface of a recording medium can be used instead of a synchronizing signal generation circuit according to an internal clock.

    摘要： The present invention provides a mechanical sensor high in sensitivity (GF) and reliability. The mechanical sensor comprises an insulating substrate, a pair of electrodes formed on the insulating substrate, and a piezoresistance element formed by connecting the electrodes. The piezoresistance element is substantially made of a glass of the PbO--SiO.sub.2 --B.sub.2 --O.sub.3 --Al.sub.2 O.sub.3 system comprising 73.1 to 86.7 wt % of PbO, 9.7 to 22.2 wt % of SiO.sub.2, 2.5 to 5.0 wt % of B.sub.2 O.sub.3 and 0.9 to 3.6 wt % of Al.sub.2 O.sub.3 and a ruthenium oxide powder dispersed in the glass. The piezoresistance element is formed by coating and baking a paste containing the ruthenium oxide powder, a powder of the glass and an organic binder.
