Filed: 1981-10-09
Abstract: PURPOSE:To improve stability without damaging responsiveness of a display, by a method wherein, in case an unexpected abnormal data due to disturbance enters when a data is steady, the abnormal data is compressed to continue to perform an averaging. CONSTITUTION:A latest input data is compared with a means value of preceding input data, and if the result is within a predetermined allowable range, the latest input data is adopted as it is to perform a mean computation, and if it exceeds the allowable range, the latest data is replaced with a value, which is compressed to a tendency approximating a mean value of preceding data, to perform a means computation. If it exceeds in succession more than a predetermined number of times, it is handled as normal measurements.

IPC: G11B20/14
Filed: 1987-06-29
Abstract: PURPOSE:To always obtain stable read data with high reliability without being affected by the fluctuation of the carrier velocity of a magnetic medium to be recorded even when it occurs, by performing the discrimination of data after reading all of the recording planes. CONSTITUTION:The inversion time of a magnetized inversion signal in which a reproducing signal from a read magnetic head 1 is A/D converted is measured and stored at the time of reading and carrying a magnetic recording medium, and the data is discriminated in order by the interval of a magnetized inversion time stored at a post-processing after completing carrying. At this time, the data discrimination time of a decision bit is decided corresponding to the fluctuation of the magnetized inversion time for the fluctuation of velocity at that time by moving and changing criterion in order setting always the magnetized inversion time per bit of the decision bit as reference. In such a way, it is possible to separate the signal from a noise, and also, since the criterion changes following the fluctuation of the magnetized inversion time, that is, that of the carrier velocity, no influence of the noise is received, and the data can be always discriminated correctly.

Title: Temperature fuse
Inventor: NISHIKAWA MASAYASU
IPC: H01H37/76
Filed: 1992-06-22
Abstract: PURPOSE:To enhance shock-resistivity and rated current capacity of a temperature fuse by using a metallic body coated with an insulating material as a cylindrical case for accomodating a fusible alloy with lead wires connected to its both ends. CONSTITUTION:Lead wires 2 and 2 are connected to both ends of a rod-like fusible alloy 1 to be fused in excess of a preset temperature. The fusible alloy 1 is accomodated in a cylindrical case 9 consisting of a metallic cylinder 7, internal and external surfaces of which are coated with an insulating material 8 (for example, a silicone high molecular insulating material). Both ends of the cylindrical case 9 are sealed with sealant resin 4 and 4, while the lead wires 2 and 2 are sealed and fixed, so as to manufacture a fusible alloy type temperature fuse 6. Accordingly, since the cylindrical case 9 is mainly composed of the metallic cylinder 7, its strength against shock is enhanced so that no breakage take place when being handled, such as for attaching to an apparatus. In addition, since no breakage takes place due to an internal spark caused when large current is shut off, its rated current capacity can be increased as the result.
