A first centrifugal impeller and a second centrifugal impeller are arranged in such an orientation that back sides of the first centrifugal impeller and the second centrifugal impeller face to each other. Bearings are cylindrical roller bearings and a thrust bearing. The cylindrical roller bearings are arranged at two axially spaced supporting positions respectively, and support a radial load applied to the rotating shaft. The thrust bearing supports a thrust load applied to the rotating shaft.

A data conversion unit includes a first input/output unit, a second input/output unit, an encoder, a decoder, a random number generator for generating random number data, and a control unit which selects a first, second and third setting function. The first setting function sets the data conversion unit to input data from the first input/output unit, encode data by the encoder, and output the encoded data from the second input/output unit. The second setting function sets the data conversion unit to input data from the first input/output unit, replace the data with the random number data generated by the random number generator, and output the random number data from the second input/output unit. The third setting function sets the data conversion unit to input encoded data from the second input/output unit, decode the encoded data by the decoder, and output the decoded data from the first input/output unit.

A first compression stage and a second compression stage being arranged at positions adjacent to each other. The first centrifugal impeller and the second centrifugal impeller are arranged in such an orientation that back sides of the first centrifugal impeller and the second centrifugal impeller face to each other. A connection flow path is formed in the first housing and the second housing for introducing the compressed fluid from the first compression stage into the second compression stage. An upstream portion of the connection flow path is formed integrally with the first housing, and a downstream portion of the connection flow path is formed integrally with the second housing.

To produce a hydrogen storage alloy by melting a hydrogen storage alloy having a body-centered cubic crystal structure without using a refractory crucible and solidifying a molten alloy by a unidirectional solidification process. The unidirectional solidification is carried out by a cold crucible induction melting method at a moving speed of a solid-liquid interface in the range of 10 to 200 mm/hr by using a water-cooled metal crucible in a vacuum or an inert gas atmosphere.

The disclosure describes a print tape which allows a separating sheet to be removed easily and quickly without bending the print tape and a tape cassette containing the tape. The print tape is accommodated in the tape cassette and has a tape base material, an adhesive agent layer and a separating sheet. Side portions are each provided adjacent both sides, in a width direction, of the tape base material. A back scoring portion is provided in a center in the width direction of the separating sheet. Therefore, both sides in the width direction of an end portion of the print tape can be gripped and pulled in a direction in which they separate from each other. As a consequence, the separating sheet separates along the back scoring and a center portion of the tape base material is freed for application. Because of the structure, the separating sheet can be peeled easily and quickly from the printed base material without bending the print tape.
