摘要:
A steering mechanism for a vehicle comprising a first control member for operating a steering clutch and a steering brake on the left side of the vehicle, a second control member for operating a steering clutch and a steering brake on the right side of the vehicle, first link means connecting the first control member to the steering clutch and the steering brake on the left side, second link means connecting the second control member to the steering clutch and the steering brake on the right side, and a third control member and third link means connected thereto for simultaneously operating the left and right steering brakes. The first, second and third link means are made operative about vertical rod members to provide a flat compact mechanism. The third link means operates the steering brakes with a force increasing with the brake operating movement of the third control member to ensure effective braking action.

This invention relates to a production process of formed activated coke for SOx and NOx removal which is employed in treatment systems for various flue gases and the like.The formed activated coke for SOx and NOx removal obtained in accordance with the process of this invention has excellent pressure resistance, abrasion resistance and impact strength and also superb SOx- and NOx-removing ability, so that the coke is suitable for use in moving-bed, SOx and NOx- removing systems.The formed activated coke for SOx and NOx removal can of course show excellent SOx- and NOx-removing effects when employed in conventional SOx- and NOx-removing processes and, moreover, owing to its characteristic high NOx-removing ability, is suited for the removal of NOx from low-SOx flue gas of a fluidized-bed combustion boiler or cogeneration power plant.According to the process of this invention, dried, formed activated coke prepared from coal as a raw material is reacted with SO.sub.3 gas at 100.degree.-300.degree. C., followed by heat treatment at 300.degree.-600.degree. C. in an inert atmosphere.

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 method for producing a cable-sealing member is disclosed. The method comprises forming a formed rubber including a first plane and a second plane that oppose in a thickness direction and a side plane that bridges a peripheral edge of the first plane and a peripheral edge of the second plane. The method further includes rotating the formed rubber with one axis in the thickness direction as a rotary axis while a holder is applied over the side plane of the formed rubber and, meanwhile, inserting a cutting blade from the first plane into the formed rubber to form a ring-form slit portion and stopping the cutting blade just in front of the second plane, leaving a slit-form ring unbored on one side.

A robot arm and an apparatus for transferring an article. The robot arm includes a movable hand for holding the article. A first arm has a proximal end that rotatably supports a drive pulley and a distal end that rotatably supports a driven pulley. The pulleys are connected to each other by a belt. A second arm and a third arm each have a proximal end and a distal end. The proximal ends of the second and third arms are pivotally supported by the driven pulley. The distal ends of the second and third arms are pivotally coupled to the hand. The driven pulley, the second arm, and the third arm cooperate with the hand to define a parallel linkage mechanism. A first motor pivots the first arm about its proximal end. A second motor rotates the drive pulley. A pivoting mechanism pivots the second arm about its proximal end relative to the first arm in correspondence with the pivoting of the first arm.

Disclosed is a method of fabricating a polycidegate in semiconductor device which has a step of forming a conductor film of polysilicon on a substrate, a step of forming an ion implanted layer by implanting nitrogen ions into the polysilicon conductor film, and a step of forming a low resistance conductor film of titanium on the non-monocyrstalline conductor film. When a field effect transistor is formed by this method, using titanium nitride and/or TiSi.sub.2 alloy of the polysilicon conductor and low resistance conductor of titanium by heat treatment as a gate electrode material, the thickness of the alloyed layer is uniform, and breakdown of the gate insulating film due to local diffusion of low resistance conductor is not induced. In other embodiments, oxygen ions and silicon ions are also employed to form thin layers of tunnel oxide and amorphous silicon, respectively.
摘要:
Method for measuring power supply current, e.g., standby current of a random access memory in which, before starting measurement of the power supply current, data is read-out from memory cell of the random access memory and opposite data is written in the memory cell so that the random access memory enters into an unstabilized state. By use of this method, the measurement of the maximum power supply current can be conducted precisely.
