Title: Artificial snow making and device thereof
Inventor: ISHIHARA KOJI
IPC: F25C3/04
Filed: 1990-09-05
Abstract: PURPOSE:To make it possible to form a huge amount of snow with a dried quality by emitting microwaves at water droplet groups ejected from a nozzle in the ambient temperature less than 0 deg.C. CONSTITUTION:Water droplets ejected from a nozzle 3 drop their own temperature, exchanging heat against the ambient air and easily producing an excessively cooled state. Microwaves from a microwave generator 2 are emitted at water droplet groups 5, which are ejected in the air and excessively cooled. This excessively cooled state is broken by turning the polarized water molecules. As a result, the water droplets start freezing in the air, If the ambient temperature is near 0 deg.C (less than 0 deg.C). Moreover, they are turned into snow with a minimum content of moisture and fall down to the ground. The microwaves emitted from the microwave generator 2 should be preferably waves with directivity at 2.45Ghz to comply with the allowable band specified by law. Therefore, it is recommended that the microwaves be emitted by way of a parabola having an excellent directivity.

Title: Method and apparatus for controlling instruction prefetching of magnetic tape device

Filed: 1985-10-22
Abstract: PURPOSE:To improve the processing efficiency by providing the 1st mode detecting the tape end logically to control the instruction prefetching and the 2nd mode detecting the actual tape end so as to control the instruction prefetching. CONSTITUTION:When the magnetic tape 16 of a magnetic tape section 1 runs and a region near the end EWA of the tape 16 is detected, a prefetching control section 3 counts the running distance of the tape 16 from the point of time near the end region and when the count reaches a prescribed value, a simultaing tape end EOT is obtained. Thus, the tape warning area TWA is prolonged by quickening the EOT detection point of time in this way. Thus, the performance deterioration of the streaming running is prevented. When the tape running distance reaches the limit, a logical EOT is set. In this mode, the number of prefetching instructions is not reduced until this point is arrived. Then in the physical EOT mode, the number of the prefetching instructions is reduced during the detection of EOT of the tape 16 based on the EWA detection.
