  • Patent number: 10388536
    Abstract: Provided is a method for controlling the rate of etching of a SiC substrate based on a composition of a storing container. The etching method of the present invention is for etching the SiC substrate by heating the SiC substrate under Si vapor pressure, in a state where the SiC substrate is stored in a crucible. The crucible is formed of a tantalum metal, and has a tantalum carbide layer provided on an internal space side of the tantalum metal, and a tantalum silicide layer provided on the side further toward the internal space side than the tantalum carbide layer. The rate of etching of the SiC substrate is controlled based on difference in a composition of the tantalum silicide layer.

  • Patent number: 10207700
    Abstract: A hybrid type work vehicle includes a power source, a traveling unit, a hydraulic work unit, an accelerator pedal, a brake pedal, an operation lever device, and a control apparatus. The control apparatus is configured such that when the current operation state is determined to be that of an excavation work which is a combined operation of the traveling unit and the hydraulic work unit and the output power limitation signal is outputted, the control apparatus limits the output power of the traveling unit. The control apparatus is also configured to decrease the tilting angle of the hydraulic pump, such that a ratio between the output power of the traveling unit and the output power of the hydraulic work unit is maintained at a preset ratio.

  • Patent number: 9890517
    Abstract: A hybrid wheel loader includes a control device (200) that estimates output power of an engine (1) and an electricity storage device (11) when the hybrid wheel loader is inferred on the basis of output values of detectors (62, 63) to be traveling towards an object of excavation in order to perform an excavating work, and then, if the output power is less than target power considered necessary for the excavating work, accelerates the engine (1) to a target revolution speed while increasing the electric power supplied from the electricity storage device to a traveling motor (9). Accordingly, power necessary for excavation can be drawn from the engine even when the engine revolution speed is low and there is a fear of power deficiency occurring at the time of the excavating work.

  • Patent number: 9556590
    Abstract: This invention includes a hydraulic pump (9), a working implement (107) having a lift cylinder (13) driven by a hydraulic fluid supplied from the hydraulic pump (9), an operating device (104) for operating the working implement (107), a traveling motor (7) for driving wheels, and a main controller (100). When the lift cylinder (13) fails to operate despite an extending instruction being imparted to the lift cylinder (13) via the operating device (104), the main controller (100) reduces a limit value for an increase rate of a torque required in the traveling motor (7) to a value smaller than that applied when the lift cylinder (13) operates. With this configuration, occurrence of wheel slip during lifting of an object to be carried can be reduced.

  • Patent number: 9249557
    Abstract: When the total value of demanded hydraulic power and demanded traveling power is larger than the sum of the engine power that can be output by an engine (1) and of the discharge power that can be discharged by an electrical storage device (3), the actual power of a hydraulic pump (9) is increased from the value at the time of demand toward the demanded hydraulic power under the constraint of a predetermined limit. While the power of the hydraulic pump is being subjected to the predetermined limit, the actual power of the traveling motor is decreased from the value at the time of demand by a value smaller than the magnitude of the predetermined limit. This prevents worsening of ride comfort attributable to the distribution of power between the hydraulic pump and the traveling motor.

  • Patent number: 9151017
    Abstract: A hybrid wheel loader is provided, the hybrid wheel loader achieving high work efficiency even with a short supply of power to be output relative to a vehicle power requirement. The hybrid wheel loader includes a motor generator 6 connected to an engine (1), a hydraulic pump (4) connected to the motor generator, a hydraulic actuator (51, 52, 53) driven by hydraulic oil supplied from the hydraulic pump, a travel electric motor (9) for driving wheels (61), and an electrical storage device (11) connected to each of the motor generator and the electrical storage device via respective inverters (7, 10). When a total requirement power value is greater than a hybrid output upper limit value, either one of a hydraulic requirement power value Pf and a travel requirement power value Prun is limited according to an operation of the wheel loader to thereby set the total requirement power value to a value equal to, or less than, the hybrid output upper limit value.
