摘要:
The invention provides a swing drive device that is capable of energy conservation by limiting loss of hydraulic fluid pressure energy resulting from discharge of the hydraulic fluid pressure energy as thermal energy into the air during acceleration or deceleration of swinging action and transforming motion energy to electric energy during deceleration of swinging action, and also enables cost reduction by making components and parts compact.

In a construction machine provided with a control unit for outputting actuating commands to actuators based on operating signals from operating levers, interlocking relationships between the operating levers and the actuators can be set as desired respectively, while avoiding enlargement of the memory. Interlocking relationships desired by an operator are adapted to be input into a control unit from a service tool, and the control unit is provided with a memory for rewritably storing the interlocking relationships thus input.

The present invention provides a living body healing, having an accelerating activity in the regeneration ability relating to the cure of damages of cells or tissues caused by toxicity of a drug or a wound in a living body, having high safety, and also not causing any side effect even administered for a long period of time. Problems are solved by a living body healing accelerator containing as an active constituent a mixture of a culture solution obtained after cultivation of a microorganism belonging to the Aureobasidium sp. and mycelia of the microorganism cultivated in the culture solution. The living body healing accelerator of the present invention is preferable used for reducing side effects of an anticancer drug, preferably used for acceleration of healing of a wound, and in addition, preferably used for acceleration of normalization of a blood glucose level and for alleviating a pathological state of leukemia.

A hydraulic control system in a working machine includes hydraulic cylinders that make a working part ascend and descend; a first main pump that suctions oil from an oil tank and discharges the oil; an accumulator that accumulates oil discharged from weight holding side oil chambers of the hydraulic cylinders when the working part descends; and a hybrid pump that suctions accumulated oil pressure in the accumulator and discharges the oil pressure. When the working part ascends, discharged oil from the hybrid pump is supplied to the weight holding side oil chambers of the hydraulic cylinders. When an insufficient supply flow from the hybrid pump to the hydraulic cylinders exists, a complementary flow corresponding to the insufficient supply flow is supplied from the first main pump to the weight holding side oil chambers of the hydraulic cylinders.

The present invention provides a composition containing β-glucan in which the physiologically active effects of β-1,3-1,6-glucan contained in a cultured composition of a bacterium belonging to the genus Aureobasidium sp. are further enhanced, and a constipation-relieving drug, preparation an immunopotentiator, and a skin moistening agent using the composition. A composition containing β-glucan, which contains a cultured composition containing β-1,3-1,6-glucan obtained by culturing a bacterium belonging to the genus Aureobasidium sp. and lactic acid bacterium cells, is obtained. This composition containing β-glucan is employed as an active ingredient of a constipation-relieving drug, an immunopotentiator, or a skin moistening agent. Aureobasidium pullulans M-1 (FERM BP-08615) is preferable as the bacterium belonging to the genus Aureobasidium sp. Moreover, Enterococcus faecalis is preferable as the lactic acid bacterium. It is still preferable that the lactic acid bacterium has been killed by heating. Furthermore, the content of the cultured composition in solid matters preferably ranges from 1 to 80% by mass in terms of β-1,3-1,6-glucan, while the content of the lactic acid bacterium cells preferably ranges from 4 to 95% by mass.
摘要:
The detectors, which are adapted to detect operation signals from operating devices for inputting actuation commands to a work machine, and hydraulic system locking switch, which is adapted to command locking so as to halt the work machine or unlocking to enable the work machine to resume working, are connected to a logic circuit adapted to compute the method of locking the work machine based on signals input from these components. A hydraulic system locking electromagnetic selector valve adapted to maintain or release the work machine at or from the locked state is connected to the logic circuit. In case an unlocking command is sent in the situation where there is an outstanding operation signal input to the work machine, the logic circuit maintains the work machine at the locked state until a safety check is performed. By commanding unlocking of the work machine after commanding its locking in the state where there is no outstanding operation signal input to the work machine, the work machine is released from the locked state.

The composite operation efficiency can be improved in a work machine with a plurality of hydraulic actuators. In the control section the flows to be shared to the respective hydraulic actuators are calculated on the basis of the permissible flow in compliance with an operating quantity of an operating tool, and control commands are outputted to an electromagnetic pressure valve so that the corresponding shared flows are supplied to the respective hydraulic actuators.

A system for controlling the cutting operation of a hydraulic backhoe having a bucket pivotally joined to one end of an arm, the other end of which is pivotally joined to one end of a boom having another end pivotally supported on a self propelled vehicle. Hydraulic jacks are provided for pivoting the boom relative to the vehicle, the arm relative to the boom, and the bucket relative to the arm. During each cutting operation the actual bucket speed relative to the arm and the actual arm speed relative to the boom are sensed and referred to a set of fuzzy control rules for obtaining command values for controlling the boom, arm and bucket jacks. The fuzzy control rules are so determined and utilized as to enable the machine to automatically take a cut in a manner suiting the hardness or other characteristics of the soil.

An apparatus for controlling the lifting operation comprising an operation mode selection switch which is selectively set to an ordinary operation mode or to a lifting operation mode and a hydraulic circuit isolating means. The hydraulic circuit isolating means isolates the hydraulic circuit into a running drive hydraulic circuit which feeds the pressurized fluid of one of the variable-capacity hydraulic pumps to the actuators of the running apparatuses when the operation mode selection switch is set to the lifting operation mode and a hydraulic circuit for driving the apparatus on the side of the turning body, which feeds the pressurized fluid of the other variable-capacity hydraulic pump to the actuators other than those of the running apparatuses.
