  • Patent number: 9741594
    Abstract: Each of substrates which are sequentially loaded into an apparatus is transferred to one of empty (available) cooling units, and the cooling unit is reserved as a unit to be used for performing a cooling treatment after a post-exposure bake process for the substrate and the reservation information is stored. After one of the cooling units is reserved in advance before the post-exposure bake process, the substrate is transferred from the cooling unit to one of heating units without being subjected to a cooling treatment and is subjected to a post-exposure bake process therein. After the post-exposure bake process, the substrate is transferred from the heating unit to the reserved cooling unit which is reserved in advance and subjected to a cooling treatment therein.

  • Patent number: 9309649
    Abstract: A work machine equipped with an automatic hammering function is capable of preventing breakage of the hammer caused by blank firing. Hydraulic oil fed to a hydraulic breaker at the distal end of a work machine is controlled by first and second spools. Operating an operation lever so as to contract single rod type boom cylinders to press the hydraulic breaker against an object to be crushed. Head-side pressure and rod-side pressure of the boom cylinders are respectively detected by pressure sensors. Any one of switches is used to switch the mode of automatic hammering operation between an automatic hammering inhibiting mode and an automatic hammering authorizing mode. In the automatic hammering authorizing mode, a controller controls the first and second spools of the hydraulic breaker so as to open them only when head-side pressure and rod-side pressure of the boom cylinders are in a given range of pressing force.

  • Patent number: 9103095
    Abstract: A controller controls the solenoid-operated variable pressure relief valves that are provided to control, at set pressures that can be electrically commanded, pressure of hydraulic oil fed to an attachment cylinder. The controller is provided with a control logic that is capable of controlling the aforementioned solenoid-operated variable pressure relief valves. The control logic performs the aforementioned calculation by compensating for pressure override characteristics of each solenoid-operated variable pressure relief valve based on input signals related to the set relief pressure for and a relief valve passing flow rate of the solenoid-operated variable pressure relief valve, and outputting to the solenoid-operated variable pressure relief valve command signals related to the adjusted set relief pressure resulting from the compensation of the pressure override characteristics.

  • Patent number: 7343316
    Abstract: A work management apparatus generates a temporary shift table in which scheduled work times of employees are temporarily set, based on an employee information file and work management file stored in a file memory. The work management apparatus sends the generated temporary shift table to a plurality of portable terminals over a network. When receiving, over the network, response information sent from the plurality of portable terminals in response to the sent temporary shift table, the work management apparatus generates a settled shift table in which scheduled work times of employees are settled, based on the received response information. The work management apparatus automatically sends the generated settled shift table to the plurality of portable terminals over the network.
