摘要:
A control change system for a backhoe in a construction vehicle, comprising a plurality of pilot valves for generating a pilot pressure corresponding to operations of a first and a second control levers, respectively, and a hydraulic switching unit for relaying the pilot pressure from the pilot valves and supplying the pilot pressure to a plurality of control valves. This switching unit includes a plurality of slidable spools for supplying the pilot pressure from the pilot valves selectively to the control valves. The control system further includes a first and a second switching members for selectively sliding the plurality of slidable spools. The first switching member is operable to select the swing cylinder or the hydraulic motor to be controlled by a shift in one direction of the first control lever. The second switching member is operable to switch interlocks between the first and second control levers and a boom cylinder and an arm cylinder.
摘要:
A control change system for a hydraulic working vehicle having a plurality of hydraulic actuators operable by control levers each shiftable to a plurality of control positions. This system includes a plurality of pilot-operated control valves for controlling pressure oil supply to the hydraulic actuators, respectively, pilot pressure generating valves for generating a pilot pressure in accordance with the control positions of the control levers, and a pilot pressure switching unit for receiving the pilot pressure from the pilot pressure generating valves and outputting the pilot pressure selectively to the control valves. The pilot pressure switching unit includes a plurality of spools slidable to change communicating passages between a pilot pressure input section and a pilot pressure output section of the switching unit.

A control section (50) of a chair-type massage machine (1) is configured so that air cells (7c) press the area around the lumbar of the user supported on a backrest section (3) to push up the area in conjunction with the backward tilting of the backrest section (3) performed using an actuator (37).
摘要:
Method for the regeneration of an activated carbon having adsorbates adsorbed therein characterized by removing the adsorbates by liquid dimethyl ether or a mixture of liquid dimethyl ether and water. By such method, the spent carbon can be effectively regenerated without degrading the absorption capacity and mechanical strength thereof. Further, valuable substances in the desorbed adsorbates can be effectively concentrated and recovered by a simple additional operation.

Disclosed is a chair-type massaging apparatus that is capable of massaging lower thighs freely and precisely in pressing angles or pressing positions with a user seated therein and allows the user to assume a desired posture without interference. A chair-type massaging apparatus (1) of the present invention comprises a leg rest (4) including a support portion (7) configured to support lower thighs (22) of a user, and massaging portions (8) configured to protrude and retract to press the lower thighs (22) of the user. The support portion (7) includes protrusible portions (9) that is mounted on both sides in the rightward and leftward direction and is protrusible to rise up inward in the rightward and leftward direction and is retractable. The massaging portions (8) are mounted on the protrusible portions (9). With the protrusible portions (9) and the massaging portions (8) retracting, the protrusible portions (9) and the support portion (7) located inward relative to the protrusible portion (9) in the rightward and leftward direction and the massaging portions (8) form a substantially flat surface.
摘要:
The phosphorus-reduced cow milk of the invention contains a reduced proportion of phosphorus of 1.0 g to 2.0 g per 100 g of protein in the cow milk, the weight ratio of phosphorus to calcium being 1:2, nearly the same as that of human milk. The ratio is most adequate for calcium absorption and is suitable as food for kidney-disease patients with reduced calcium-absorbing function, persons of old age and hyperphosphatemia patients. Moreover, the phosphorus-reduced cow milk of the invention in which only phosphorus component is selectively removed and none of other component is lost maintains the value of cow milk as perfect food.

Disclosed is a chair-type massaging apparatus that is capable of massaging lower legs freely and precisely in pressing angles or pressing positions with a user seated therein and allows the user to assume a desired posture without interference. The chair-type massaging apparatus of the present invention typically includes a leg rest including a support portion configured to support lower legs of a user, and massaging portions configured to protrude and retract to press the lower legs of the user. The support portion includes protrusible portions that is mounted on both sides in the rightward and leftward direction and is protrusible to rise up inward in the rightward and leftward direction and is retractable. The massaging portions are mounted on the protrusible portions. With the protrusible portions and the massaging portions retracting, the protrusible portions and the support portion located inward relative to the protrusible portion in the rightward and leftward direction and the massaging portions form a substantially flat surface.
