Title: Steering device for working vehicle
Inventor: KUROHARA KAZUAKI
IPC: B62D7/14
Filed: 1989-03-30
Abstract: PURPOSE:To permit the rough position adjustment of a stopper for regulating the max. steering angle by providing an elastic deflection onto one drag link, in the constitution in which each drag link of the front and rear wheel steering mechanisms is connected to a pitman arm interlocked with a steering wheel. CONSTITUTION:The steering device for a four-wheel steered working vehicle such as lawn mower is constituted by connecting the drag link 22 of a steering mechanism A for front wheels 1 and the drag link 25 of a steering mechanism B for rear wheels 2 with a pitman arm 12 which is turned by a steering wheel 9. The front and rear wheels 1 and 2 are steered in the reverse direction each other by the operation of the steering wheel 9, and the max. steering angle of the front and rear wheels l and 2 is regulated by stoppers 26 and 27. In this case, the drag link 25 for the rear wheels 2 is formed into bent form, and after the knuckle arm 24 of the rear wheel 2 contacts a stopper 27 by the elastic deflection due to the deflection of the link 25, the stopper 26 on the knuckle arm 20 of the front wheel 1 collides with an axle frame.

Abstract: PURPOSE:To reduce an amount of work consumed in a fluid pressure driving device by putting a lever, driven by the second fluid pressure cylinder, in contact with an exhaust valve opened or closed under control of the fluid pressure and maintaining the exhaust valve closed. CONSTITUTION:An exhaust valve 40, formed in opening out type with its pressure receiving piston 41 arranged in a fluid pressure cylinder, is opened or closed by oil pressure of a valve opening oil chamber 42 and a valve closing oil chamber 43. Through control by solenoid valves 71, 72, 73, 74, a pump 54 and a pressure accumulator 55 apply oil pressure to each oil chamber 42, 43 and also let it go from each chamber 42, 43, and the exhaust valve 40 is opened or closed. A lever 83 driven by the second oil pressure cylinder 81 is provided so as to be able to contact one end of the exhaust valve 40, and maintains said valve 40 closed at the valve closing time against the gas pressure in a cylinder 10. This method eliminates requirement for raising the pressure in an oil pressure circuit and can reduce an amount of work consumed in a fluid pressure driving device.

Abstract: PURPOSE:To prevent deterioration in image formation characteristics and a decrease in cleaning characteristics by mounting a changeover member on a cleaning device and releasing its pressing by a spring member, and detaching the changeover member and pressing the cleaning device by the spring member. CONSTITUTION:A slit which slants slightly is formed in a flank of a rail member 32 and this opening is higher than the fitting position of a formed wire 28, which is then presses against the internal flank of the rail member 32 strongly.

IPC: B60R21/231
Filed: 1995-04-06
Abstract: PURPOSE: To expand an air bag simply assembled in the straight and vertical direction by providing a gas flow inlet slantingly in the lateral direction. CONSTITUTION: The gas flow inlet 21 provided on the rear face of an air bag 20 is inclined at an angle of θ in the lateral direction. This gas flow inlet 21 is provided in such a way that the side of the jet nozzle 19 of a hybrid type inflater 18 is attached, is placed upper position than the other side. When the air bag 20 is expanded by the hybrid type inflater 18, the left side 20L of the air bag 20 is liable to become low and the right side 20R is liable to be high because of the inclination of the gas flow inlet 21. However, the gas jetted from the hybrid type inflater 18 works to incline the air bag, pushing up the left side 20L. The inclination of the air bag due to gas jetted and that due to the inclination of the gas flow inlet 21 are canceled, expanding the air bag 20 without inclination.

Abstract: PURPOSE:To replace only one of a probe and a connector even if the wiring of one of the probe and the connector is broken by connecting lead wires from the ultrasonic wave probe to a connecting board, and inserting the connector into the connecting board. CONSTITUTION:Lead wires 12 which are taken out of a transceiver element 11 of an ultrasonic wave probe are connected to a connecting board 13 beforehand. Pins 14a of a connector 14 are inserted into the connecting board 13 which forms an integrated body together with the transceiver element 11.

Title: Curl removing device
Inventor: NAKANO RYUNOSUKE
IPC: H04N1/00
Filed: 1985-04-17
Abstract: PURPOSE:To make it possible to eliminate the problem of generation of irregular feed of a rolled paper sheet due to variations in the diameter of the rolled paper sheet, by providing such an arrangement that the space between an curved guide section and a curl removing roller is automatically adjusted in accordance with the tension of paper of the rolled paper sheet, which varies in dependence upon variations in the diameter of the rolled paper sheet. CONSTITUTION:When the diameter of a rolled paper sheet is maximum and when a tension is effected in the paper sheet 7 caused by forces F1, F2 which are exerted similar to the conventional one, a curl removing roller 3 is pushed up by the paper sheet 7 to shift a bearing 11 to the top section of an elongated hole 10a, and therefore, a gap 2 is enlarged at a maximum value so that the frictional resistance to the paper sheet 7 by the roller 3 and a curved guid section 1 becomes minimum, resulting in that the force F2 comes to be also minimum. Then, the spring constant of a torsional coil spring 21 is set such that the load upon the bearing 11 is increased to comensate the reaction of the force F2 due to reduction of the diameter of the rolled paper sheet, and therefore, although the force F1 increases from M3 to M2 since the roller 3 is depressed down due to the reduction of the force F2 and the gap 2 is narrowed, the force F2 simultaneously decreases from L3 to L4 so that the variation N2 in the value of F1+F2 is greatly decreased in comparison with the conventional one, thereby it is possible to prevent irregular feed.
