  • Patent number: 10247207
    Abstract: When an engine stall is likely to occur, the pressure of the back pressure chamber of a relief pressure valve is released to adjust the relief pressure of the relief pressure valve. This actuates a pressure compensating circuit to release the pressure in a control circuit to an oil tank. Thus, a rapid increase of the pressure due to a cargo handling operation is restricted, and an engine stall due to insufficient torque of the engine is avoided.

    Abstract: In an operation-mode indicating system, a first light emitting device is located within a peripheral visual field of an operator and is controllably connected to a controller. The peripheral visual field is defined around a center visual field of the operator while the operator is looking at a predetermined site. A body support apparatus is capable of performing an operation to the predetermined site. The controller controls the first light emitting device to emit first light in a first operation mode of the body support apparatus and second light in a second operation mode of the body support apparatus.

  • Patent number: 9835185
    Abstract: A hydraulic mechanism is mounted on a forklift. The hydraulic mechanism has a control valve and a pressure compensation circuit for compensating pressure within the hydraulic mechanism. The pressure compensation circuit has a relief pressure valve and an unloading valve for releasing pressure within the pressure compensation circuit to a discharge oil passage. Upon instructed to perform cargo handling operation, the unloading valve is switched to an open state, and the relief pressure valve is thereby actuated, so that rapid increase of pressure within the circuit is avoided. Further, the unloading valve is switched to an open state, and the pressure within the hydraulic mechanism is thereby released to the discharge oil passage, so that the cargo handling operation by the tilt cylinder and the lift cylinder is restricted.

  • Patent number: 9812302
    Abstract: In a magnetron sputtering apparatus configured such that a magnetic field pattern on a target surface moves with time by means of a rotary magnet group, it is to solve a problem that the failure rate of substrates to be processed becomes high upon plasma ignition or extinction, thereby providing a magnetron sputtering apparatus in which the failure rate of the substrates is smaller than conventional. In a magnetron sputtering apparatus, a plasma shielding member having a slit is disposed on an opposite side of a target with respect to a rotary magnet group. The distance between the plasma shielding member and the substrate is set shorter than the electron mean free path or the sheath width. Further, the width and the length of the slit are controlled to prevent impingement of plasma on the processing substrate. This makes it possible to reduce the failure rate of the substrates.
