  • Patent number: 8932183
    Abstract: A training system for training of part of a trainee's body includes a training machine, a control device controlling the training machine, and a display unit displaying a game screen. The training machine imposes a load on the trainee, with an MR-fluid load generating unit using MR fluid, which has viscosity varying with a magnetic field strength. The load is calculated on the basis of a target load and a relationship between the current in the MR-fluid load generating unit and the load generated by the MR-fluid load generating unit. The control device produces the game screen in correspondence with the trainee's training motion detected by a displacement detection sensor, and makes the display unit display the game screen, while controlling the load in the training machine.

  • Publication number: 20140352816
    Abstract: A hydraulic pressure control apparatus includes a first pressure regulating valve for reducing an initial oil pressure (line pressure) of a working oil, a solenoid-operated valve for converting the oil pressure, which has been reduced in pressure, into a solenoid pressure, and a second pressure regulating valve for converting the line pressure of the working oil into an actuating pressure responsive to the solenoid pressure. The three valves share a single body. Further, an outlet passageway is formed along a thicknesswise direction of the body, with a relief valve being formed upwardly of the outlet passageway.

  • Publication number: 20140352824
    Abstract: A hydraulic pressure control apparatus includes a first pressure regulating valve for reducing an initial oil pressure of a working oil introduced from an inlet port, a solenoid-operated valve, and a second pressure regulating valve for converting the initial oil pressure of the working oil into an actuating pressure. The three valves share a single body. A joining boss and a relief valve, which is operable to release the working oil out of a passage in the body when the pressure of the working oil in the passage becomes equal to or greater than a predetermined threshold value, are arranged on a closed end face of the body. The joining boss and the relief valve have respective upper surfaces that are covered by a cover.

  • Patent number: 8654493
    Abstract: A first voltage dividing circuit is connected between a power feeding line to feed power from an external power supply to an internal circuit, and a fixed potential to divide a voltage of the power feeding line. A first comparator compares a divided voltage, which has been divided by the first voltage dividing circuit, with a reference voltage, and outputs a signal to turn off a power switch inserted into the power feeding line when the divided voltage exceeds the reference voltage. A first transistor is connected between a first node where the divided voltage, which has been divided by the first voltage dividing circuit, is generated, and the fixed potential, and is turned on when the voltage of the first node exceeds a set voltage.

  • Patent number: 8646776
    Abstract: A reversely-rotatable roller conveys a sheet having an image formed on its one side at a sheet conveying velocity faster than that of a conveying roller by normal rotation and then, the reversely-rotatable roller conveys the sheet to a re-conveying path by reverse rotation. The sheet conveying velocity of the reversely-rotatable roller when the reversely-rotatable roller reversely rotates is made slower than the sheet conveying velocity when the reversely-rotatable roller normally rotates so that the sheet conveying velocity of the re-conveying roller is substantially equal to or slower than the sheet conveying velocity of the conveying roller.
