  • Patent number: 12594609
    Abstract: A hydro chuck includes a shank portion provided on one end side in a longitudinal direction and having, on a leading end side thereof, a cylindrical chuck portion for gripping a gripped object and an operational portion provided on the other end side in the longitudinal direction and disposed in continuation from the shank portion. The shank portion is fixable by being inserted to a tool mount included in a machine tool. The chuck portion includes a sleeve gripping the gripped object and a fluid pressure chamber formed on an outer circumference side of the sleeve and filled with fluid, the chuck portion being configured such that in association with a rise of a pressure of the fluid inside the fluid pressure chamber, the sleeve is reduced in its diameter to grip the gripped object.

  • Patent number: 12036475
    Abstract: A control program for a game device having a storage unit configured to store points associated with players. The game device may receive a request by a player to designate at least a portion of the points associated with the first player as region points of the first player, which may in turn be correlated with a game region designated by the first player. When the first player has the most points for a particular game region, the game region may be set to be a region of the first player. When the first player disposes a first and second game region in a predetermined arrangement, such that the first and second game region has game regions between them, the game regions between the first and second game region may have their point values swapped to put the first player on top.

  • Patent number: 10967471
    Abstract: Provided is a chuck device that allows appropriate and easy setting of a discharging direction of working fluid. A chuck device configured to be attached to a spindle of a machine tool for gripping a cutting tool, in which inside the chuck device, there are provided a passage in which a working fluid flows and a discharge opening provided at a leading end opening of the passage through which the working fluid is discharged toward to the cutting tool. A discharging direction of the working fluid from the discharge opening is set opposite to a rotational direction of the cutting tool and set with a tilt of an angle calculated by a mathematical formula to a tangential direction of a rotation trajectory of the center of the discharge opening relative to a direction of an axis of the cutting tool.

  • Patent number: 10277452
    Abstract: A message processing system with improved maintainability, while ensuring availability, is provided. A filtering section 131 determines a degree of importance of an error message transmitted from a monitoring target server 110 and performs a process of filtering. A queue 121 receives the error message after the process of filtering by the filtering section 131 and transmits the error message to all summarizing sections 132. The summarizing section 132 then performs a process of summarizing for summarizing error messages of the same type as to the error messages after the process of filtering by the filtering section 131. A topic 122 receives the error message after the process of summarizing from one summarizing section 132.

  • Patent number: 9392537
    Abstract: The terminal according to the present application has a connection unit that connects to an access point for a communication network The terminal also has a connection control unit that scans a network registered in a connection list, subtracts access points registered in a exclusion list from the detected access points to identify access points to which connection is possible, initializes the exclusion list if an access point to which connection is possible is not identified and then again identifies an access point to which connection is possible, and selects an access point to connect to, out of identified access points to which connection in possible. The terminal further has a connection ending unit that, if the start of a connection to an access point registered in a duplicate exclusion list is detected, cuts the connection with the access point, and also deletes the corresponding network from the connection list.
