摘要： The present invention provides a method for detection of a vacuum leak of a vacuum vessel provided in an equipment, for example, an absorption chiller, and in which water and a solution (for example, lithium bromide solution) are charged. The gas in the vacuum vessel is purged by an auxiliary air pump while spraying helium as trace gas by a helium spray gun to the outer surface of the vacuum vessel under inspection of the absorption chiller, a part of the purged gas is passed through a dehumidifier where the steam is removed from the gas, a part of the purged gas is depressurized by reducing the partial pressure of the steam to zero, and it is detected by a helium-leak detector whether or not the trace gas (helium) leaks from the vacuum vessel. This method and an apparatus for carrying out the method permit to check for any vacuum leak and quantitatively determine it quickly, easily and with a high sensitivity whether the equipment under inspection is in or out of operation.

The position detection device has a primary winding and a secondary winding, and at least one excitation signal each having a predetermined periodic waveform is supplied to the primary winding to thereby generate at least one output signal each in the form of a phase modulated signal corresponding to a rotational position of a rotating member from the secondary winding directly or after having been subjected to phase shifting and appropriate arithmetic operations. The apparatus is provided with an abnormality detection section for determining an abnormality of the position detection device when the phase modulated signal has a peak value which is outside a predetermined range.
