Patent JP-S63221825-A (JP)
Title: Air purifier/dehumidifier
Inventor: KASHIWABARA NOBUJI
IPC: B01D46/42
Filed: 1987-03-09
Abstract: PURPOSE:To make the title device compact by combining a polarity reversal switching solid-state circuit which transmits predetermined polarity and reversed polarity current pulses at a fixed time interval, and a static shield casing encircling each member. CONSTITUTION:In a two-way valve V, compressed air comes from a compressed air supply source 1 passing through a drying cylinder 3, then is dehumidified and sent out of an outlet port 2 of the subject device for use. Simultaneously some amount of dried air goes back through a drying cylinder 3', discharging moisture and dust sticking to the internal filter outside the device via the two- way valve V' and a muffler 4'. After this, for instance, thirty seconds later, this passage direction is completely reversed. That is, one drying cylinder is dehumidified by a purified and dehumidified air generated by the other drying cylinder every thirty seconds. The purified and dehumidified air is always released through the outlet port 2.

Title: System for controlling load balance
Inventor: YAMAMOTO AKIRA
IPC: G06F13/10
Filed: 1988-03-09
Abstract: PURPOSE:To attain the balance of an I/O load by predicting and calculating a load state after a magnetic tape MT is transferred from a controller having a large load capacity to that having small one and selecting a transfer method which can obtain a prediction result where the load is most balanced. CONSTITUTION:It is necessary to appropriately shift the set of the cartridge type MT25 under control between controllers A23 and B24 and to balance the load. A processor A300 collects information required for the transfer of MT25 by a prediction information collection function A313, and makes a calculation execution function A315 to connect with a processor B301 so as to decide the transferring method of MT25. Information required for predicting a means queuing time is calculated while MT25 is operated. Furthermore, the mean transfer time of the set of MT25 under respective controllers is predicted and calculated when MT25 under control between both controllers A23 and B24 is transferred. As a result, it is better to select the transferring method in which the difference of the prediction result in the mean data transfer queuing time of the set of MT25 under the control of the controllers comes minimum.
