Title: Pump freezing preventing method
Inventor: NAKAMURA YUTAKA
IPC: F04D29/58
Filed: 1990-06-12
Abstract: PURPOSE:To perform drainage even with a drain cock positioned higher than an impeller so as to prevent freezing by operating a pump until no water comes out of a drain hole after opening the drain hole provided at the side wall lower part of a pump chamber for enclosing an impeller. CONSTITUTION:At the time of operating a pump, a current is applied to a motor so as to rotate a main driving magnet 2 and a following magnet 3 and also to rotate an impeller 5 to discharge water from a discharge opening 8. At this time, a drain hole 7 is closed with a drain cock. On the other hand, the drain hole 7 is opened at the time of preventing freezing so as to let water in a pump chamber 6 out from the drain hole 7. Since water in the part lower than the drain hole 7 remains, however, the pump is driven to splash water by the part, soaked in the residual water, of an impeller 5 to drain the residual water from the drain hole 7. The water in the soaked part of the impeller 5 is thereby removed, and even if the water still remains, it stays below the impeller 5. As a result, the impeller 5 is prevented from being rigidly fixed even in the case of the residual water being frozen. Redriving can be thereby performed promptly.

Inventor: JIEIMUZU ERU FUINAATEII
IPC: H01L21/82
Filed: 1990-06-13
Abstract: PURPOSE: To minimize the connection cost by halving a model initial assignment of disposed slots on a support structure, computing partial gains of each model based on electric characteristics and critical and non-critical delays corresponding to interconnections, swapping the slots to obtain a total max. gain and recovering the logic design soln. at the max. accumulated gain. CONSTITUTION: Sections of a chip divide a logic design along dashed line 64. The cost for forming sections A, B are determined, using a weighting procedure which sections a critical load/driver port connection from a non-critical load/ driver port connection in a cut assembly. Sequenced bucket vectors 68, 69 for use in the sectioning method decide ranking of the models in a section, starting from a model having a min. partial gain to a model having a max. partial gain. A pair of disposed slots are selected from the sequenced bucket vectors 68, 69 in a section so that the slot swapping provides a max. gain. This reduces required time to make the electronic design operable at a high speed.
