Title: Variable spectral reflectivity alloy and recording material
Inventor: ANDO HISASHI
IPC: G11B7/2433
Filed: 1984-09-21
Abstract: PURPOSE:To provide a variable spectral reflectivity alloy which can maintain partially different spectral reflectivities at the same temp. by incorporating Sn and Al respectively at prescribed ratios into the alloy and consisting the balance of Cu as the essential component. CONSTITUTION:The alloy of this invention is subjected to a heating and cooling treatment in the solid phase state to have at least >=2 kinds of spectral reflectivities at the same temp. and can vary reversibly the spectral reflectivities. The spectral reflectivity varies with the state in which the high-temp. phase out of said phases is quickly cooled and the standard state without quick cooling. The spectral reflectivity is reversibly changed by the heating and quick cooling in the temp. region of the high-temp. phase and the heating and cooling in the temp. region of the low-temp. phase. The compsn. of this alloy contains 15-35wt% tin and 0.01-3.0wt% Al and consists of the balance Cu as the essential component. The alloy is usable particularly for media for information recording, displaying, sensing, etc. with which the change in the spectral reflectivity with a change in the crystal structure of the alloy by the light and heat energy applied thereto is utilized.

Filed: 1987-08-06
Abstract: PURPOSE:To output a proper contact signal only without being affected by noise and reduce the cycle time by providing contact determining means for outputting a contact detection signal when a duration time of a set condition of condition retaining means becomes a predetermined time or more. CONSTITUTION:A sensor 21 detects a signal a generated when a grinding wheel of a grinder contacts a work, and a fluctuated threshold circuit 28 outputs a high level threshold VH and a low level threshold VL according to the signal a. When the signal level of the sensor becomes higher than the high level threshold, a first comparator 29 outputs a condition retaining means setting signal. A contact determining means 34 determines whether or not a duration time of a set condition of condition retaining means 31 becomes a predetermined time or more. When the duration time of the set condition becomes the predetermined time or more, a contact detection signal e is output. Accordingly, it is prevented that a lost grinding time will be unnecessarily increased because of malfunction due to a noise signal during grinding.
