Filed: 1990-11-01
Abstract: PURPOSE:To facilitate mounting and adjustment as a whole and to high accurately perform detection by providing a detecting means corresponding to a change of a distance from a constitutional member further having an extreme value to output a changing signal. CONSTITUTION:For instance, a reflecting type optical sensor 11 for outputting a signal having an extreme value relating to a change of a distance from a measured object is used and arranged in a position of outputting the extreme value before a hammer tapping a chord, and a chord tapping speed is calculated based on the lapse of time from the time of outputting the first output value to the time of outputting the second output time, before outputting the extreme value. That is, a distance between two measuring points is calculated based on the first/second output values of the output signal from the detecting means 11. Time for a chord tapping mechanism constitutional member 36 to pass through these two measuring points is detected to calculate the chord tapping speed from measured values of these distance and time. In this way, mounting and adjustment or the like can be facilitated, and the actual chord tapping speed by the hammer can be accurately detected in an automatic piano.

Abstract: PURPOSE:To prevent the lack of a bonding area and the generation of a fine clearance, and to improve the reliability of electric connection by forming a recessed section through chamfering working, etc., on the inner circumference of an opening section in an upper substrate constituting a substrate for loading a semiconductor. CONSTITUTION:A semiconductor element is loaded and mounted to a semiconductor loading section 15 for a substrate, and sealed by using an epoxy resin, etc. The inner circumference of an opening section 15a on the joining side of an upper substrate 13 is made wider than that of an opening section on the surface side to be joined. An adhesive sheet 14 section protruded from the opening section 15a on the surface side to be joined is held into a recessed section 30. As a result, the quantity of protrusion to the semiconductor loading section 15 side of the adhesive sheet 14 is reduced, and the bonding area of a lower substrate 12 is ensured. When the intermediate section of the adhesive sheet 14 is removed, the opening section 15a is made wider than that on the surface side to be joined of the upper substrate 13 and narrower than that on the joining surface side to which chamfering working is executed. Accordingly, a fine clearance due to the lack of the adhesive sheet 14 is prevented.

Title: Magneto-optical recording medium and recording and reproducing method
Inventor: MURAKAMI YOSHITERU
IPC: G11B11/105
Filed: 1992-11-06
Abstract: PURPOSE:To execute high-density recording by providing a reading-out layer which exhibits intra-surface magnetization dominant with intra-surface magnetic anisotropy within a chamber and migrates to perpendicular magnetization dominant with perpendicular magnetic anisotropy with an increase in temp. and a recording layer thereon. CONSTITUTION:A transparent dielectric substance layer 2, the reading-out layer 3, a recording layer 4, a protective layer 5 and an over coat layer 6 are formed on a substrate 1. The layer 3 exhibits the intra-surface magnetization dominant with the intra-surface magnetic anisotropy within the chamber and migrates to the perpendicular magnetization dominant with the perpendicular magnetic anisotropy with the increase in temp. Only the part where the temp. rises exhibits an extreme Kerr effect when the part where the temp. rises shifts from the intra-surface magnetization to the perpendicular magnetization. Information is thus reproduced in accordance with the reflected light from this part. The temp. of the previous reproducing part falls at the time of reproducing the next recording pit by movement of a light beam. The perpendicular magnetization shifts to the intra-surface magnetization and the extreme Kerr effect is not longer exhibited. The layer 3 shifts sharply in the magnetization from the intra-surface magnetization to the perpendicular magnetization by using GdFeCo. The noises at the time of reproducing decrease and the recording at the higher density is possible.
