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.

The plating method comprises the step of forming a resin layer 10 over a substrate 16; the step of cutting the surface part of the resin layer 10 with a cutting tool 12; the step of forming a seed layer 36 on the resin layer 10 by electroless plating; and the step of forming a plating film 44 on the seed layer 36 by electroplating. Suitable roughness can be give to the surface of the resin layer 10, whereby the adhesion between the seed layer 36 and the resin layer 10 can be sufficiently ensured. Excessively deep pores are not formed in the surface of the resin layer 10, as are by desmearing treatment, whereby a micronized pattern of a photoresist film 40 can be formed on the resin layer 10. Thus, interconnections 44, etc. can be formed over the resin layer 10 at a narrow pitch with high reliability ensured.

摘要:
Recesses are formed on one surface of a substrate. A conductive film covers an inner surface of each of the recesses. This conductive film contacts a bump of a semiconductor device to be inspected and is electrically connected to the bump. It is therefore possible to prevent damages of the bump to be caused by contact of a probe pin.

A magnetic head assembly includes: a slider; an actuator disposed on an end face of the slider; and a magnetic head unit connected to the actuator. The actuator has a structure in which multiple electrodes are arranged in a piezoelectric body, and is driven in d33 mode. In other words, when a predetermined voltage is applied to the actuator, a portion between the electrodes in the piezoelectric body expands or contracts with respect to a voltage application direction. When the piezoelectric body of the actuator expands or contracts, the magnetic head unit is deformed, and the deformation causes a change of the distance between a magnetic head (recording element and reproducing element) and a magnetic recording medium.
