Provided is a player tracking device which is operable to separate voice of a player from surrounding sound including presentation sound outputted from speakers of gaming machines and to effectively and clearly input the voice of a player with microphones. The player tracking device has two directional microphones which are arranged so as to be spaced apart; analyzes difference between sounds from relative positions of said microphones and sound data inputted from said microphones; and executes sound data processing.

Player tracking device, gaming machine, and information terminal

Provided is a player tracking device which is operable, even when an IC card is taken into a gaming machine while a player is playing a game, to read or write information from or to another IC card or the like through a simplified touch operation. The player tracking device includes: a card unit for storing information pertinent to a play outcome on the gaming machine in an IC card through wireless communication; and a touch unit for reading information from another IC card through the wireless communication.

Player tracking device and gaming machine

Provided is a game system in which when a bonus game or the like is conducted, linkage presentation using player tracking devices (PTS terminals) is performed over a plurality of gaming machines. Upon the occurrence of winning in the bonus game, a bonus servertransmits a bonus winning notification to a gaming machine in a bank in which a gaming machine having won therein is included. A PTS terminal of the gaming machine which has received the bonus winning notification transmits a linkage presentation start request to a gaming machine which operates as a presentation control server in the bank. The PTS terminal of the gaming machine which has received the linkage presentation start request broadcasts a linkage presentation execution request to a network segment of the bank. When respectively receiving the linkage presentation execution request, in response to the request, PTS terminals of gaming machines which operate as presentation execution clients perform presentation such as light emitting and sound outputting in a manner linked with one another in said bank.

A hub is supported rotatably about an axis of rotation, and the diameter thereof increases from upstream to downstream sides along a fluid flow. A plurality of impeller blades extend radially outward from an outer circumferential surface of the hub. A shroud is formed in a cylindrical shape whose diameter increases from the upstream to downstream sides along the fluid flow and joins outer circumferential ends of the plurality of impeller blades. The impeller blades are composed of upstream blade segments and downstream blade segments bonded at a bonding surface extending in a direction substantially perpendicular to the axis of rotation. The upstream blade segments are integral with at least a portion of the shroud, and the downstream blade segments are integral with at least a portion of the hub. This improves the reliability and performance of an impeller and a compressor.
