A turbocharger (A) includes a rotary shaft (), a journal hearing (A), and a bearing housing (). The journal hearing (A) includes load support surfaces (and), a first gap forming portion (F), and a second gap forming portion (F). The first gap forming portion (F) firms a first gap () in a radial direction between the load support surfaces (and) adjacent to each other in a direction of a central axis (O). The second gap forming portion (F) forms a second gap () smaller than the first gap in the radial direction between the load support surfaces (and) adjacent to each other in the direction of the central axis (O).

Rotary machine and journal bearing

A driving device includes: a shaft; and a cylindrical bush having an insertion hole into which the shaft can be inserted. The insertion hole includes an opening portion having an inner diameter decreasing from a first end surface toward a second end surface of the bush, and a small-diameter hole portion extending from an end of the opening portion to the second end surface. The shaft includes a shaft portion having an outer diameter smaller than an inner diameter of the small-diameter hole portion, and an abutment portion having an outer diameter greater than the inner diameter of the small-diameter hole portion. The bush has a sealing surface defining the opening portion. The abutment portion of the shaft abuts on the sealing surface of the bush in an axial direction of the insertion hole to seal a gap formed between the shaft and the bush inside the insertion hole.

Reduce bearing loss due to lubricating oil using a rotary shaft; a journal bearing that is provided to the rotary shaft and that rotatably supports the rotary shaft; a flange part having an opposing surface part that is arranged so as to oppose a side surface part of the journal bearing with a gap therebetween in the axial direction in which the rotary shaft extends; and a recess part provided in the side surface part or the opposing surface part. In the projected area of the journal bearing in the axial direction, the area of a section including the recess part and not forming the gap is larger than the area in which the side surface part and the opposing surface part form the gap.

An oil-drain device for a thrust bearing includes: a rotor shaft; a collar member mounted to an outer periphery of the rotor shaft; a thrust bearing supporting the rotor shaft in an axial direction; and an oil-drain space forming member defining an oil-drain space through which lubricant oil leaking from a sliding portion of the thrust bearing flows, between the thrust bearing and the oil-drain space forming member. The oil-drain space includes: an oil-drain channel defined between a first end surface of the thrust bearing and a first end surface of the oil-drain space forming member, surrounding the flange portion of the collar member; and an oil-drain port formed below the oil-drain channel, for discharging the lubricant oil flowing through the oil-drain channel outside the oil-drain space. The oil-drain space is configured to guide the lubricant oil flowing through the oil-drain channel to outside the oil-drain space via the oil-drain port, along a flow direction of the lubricant oil flowing through the oil-drain channel from an upstream side toward a downstream side in a rotational direction of the rotor shaft.

A semiconductor memory (,) is disclosed that includes a memory cell array (,) coupled to a register array section (,) that can function as a cache. Access times for misses to the register array section (,) during a continuous read operation can be reduced. A memory cell array (,) is coupled to the register array section (,) by a first transfer bus (TBT,-,to TBN,-,). First transfer bus (TBT,-,to TBN,-,) is connected to a local read/write bus (LRWBT and LRWBN) by transistors (,-,to,-,) and to register arrays (,-,to,-(,)) by first switches (,-,to,-(,)). In a continuous read operation, during a register array section miss, transistors (,-,to,-,) are turned on and the first switches (,-,to,-(,)) are turned on.
