Abstract: PURPOSE:To render variable the span between bearing portions and evenly cool the bearing portions and maintain amounts of both working liquids at a predetermined level, by combining a plurality of heat receivers and condensers having hollow chambers enclosing working liquids therein by means of vapor lines and liquid lines, and communicating one liquid line with the other liquid line through a flexible line, while communicating one vapor line or liquid line with the other condenser through another flexible line. CONSTITUTION:When temperature rise of a bearing portion on a heat receiver 1 side becomes greater than that of a bearing portion on the other heat receiver 11 side, working liquid in the heat receiver 1 upon vaporizing generates greater vapor quantity, vapor pressure and vapor temperature to be derived of greater latent heat of vaporization and thereby to cool the bearing portion on the heat receiver 1 side, namely to hold the temperature rise of the bearing portion on the heat receiver 1 side at a lower level than that of the bearing portion on the heat receiver 11 side. Then, such a hot vapor vaporized in the heat receiver 1 is introduced through a vapor line 5 to a condenser 21 to be cooled. Liquid condensed in the condenser 21, which has a temperature higher than that of liquid condensed in a condenser 2, is introduced through a liquid line 41 into the heat receiver 11. Accordingly, temperature of the bearing portion on the heat receiver 11 side is increased and thereby to hold the difference of temperature rise between both bearing portions at a minimum level. Moreover, the span between both bearing portions may be rendered variable by virtue of expansion and contraction of flexible lines 5a, 51a and 6a.

Title: Correction of error due to frequency variation for computation of digital effective value
Inventor: TANIGUCHI SHIGERU
IPC: G01R19/02
Filed: 1982-05-31
Abstract: PURPOSE:To minimize errors in the computation of effective values with variation in the frequency of AC input waveform by addition-averaging the results of the computation of AC input effective values by a product type computation theory over one cycle. CONSTITUTION:AC input waveform obtained through an instrument transformer 1 is sampled at a specified sampling cycle with an A/D converter 2 to be converted to a digital value from analog. The output of the A/D converter thus obtained is sent to an effective value computing device 3 to obtain an addition average over one cycle after the computation of effective values by a product computation thereof on the sampled value of the AC input. Regarding the AC waveform, the computation of the effective values with the correction of the frequency can be done by processing the AC input waveform obtained through an instrument current transformer 4 for reduction to a signal level like the AC voltage waveform. This enables the computation of effective values with little error only by a soft processing with a computer regardless of variation in the frequency of the AC input.
