摘要： PURPOSE:To prevent oil from being partially deteriorated at an early stage by equipping a relief valve to drain the oil to the front part of transmission case in the midst of pressure oil feed path from a pump to a control valve. CONSTITUTION:A pressure oil sent from a pump 1 is sent through an oil path 12a in the interior of a block 12, an oil path 9a in the interior of a protruding case wall 9 and an outlet pipe 10 to a control valve 5. When oil pressure in this chain of hydraulic circuit attains >= a set value, a valve 14 is transferred, the relief valve 2 is made into an open state and the pressure oil is drained from an introduction path 9b through a drain path 13 to a front part 3F of case until the relief valve 12 becomes a closed state again. Consequently, a hydraulic oil in the hydraulic circuit and a transmission oil are uniformly stirred as a whole, quality of oil is uniformed at every part and the oil is prevented from being partially deteriorated.

摘要： PURPOSE:To rapidly disengage an upper engaging part of a coupling member from an upper coupling member of working machine downward by laying an elastic member between a top link and the coupling member in the direction to enlarge an angle between the top ring and the coupling member. CONSTITUTION:A top link 4 and a lower link 6 pivoted on a body 2 and a coupling member 10 pivoted and connected to the rear of the body constitute a quadric linking mechanism. An elastic member 48 is laid in a compressed state between the coupling member 10 and the top link 4 and elastic force acts in the direction to enlarge the angle between both the coupling member 10 and the top link 4. Consequently, force to drop the lower link 6 works, a working machine 11 is grounded, then the coupling member 10 can be rapidly dropped so that the coupling member 10 can be readily released from the working machine 11.

摘要： PURPOSE:To remarkably enhance the production line speed by a method wherein kneading material consisting of cement compound is extruded in the form of a plate and, after that, surface layer material, which is fed from a hopper, is pressed against the surface of an extrudate with a roll and further pressed with a forming slipper. CONSTITUTION:Kneading material A made of cement compound consisting of cement, silica, necessary reinforcing fiber and filling material is extruded from an extruder 1 in the form of plate. the resultant formed body 1' is received by a pallet conveyor 2 and transferred beneath a hopper 4 filled with surface decorative surface layer material 3 so as to press the surface layer material 3 fed from the hopper 4 against the surface of the formed body 1' and further press it with a forming slipper 6. The feeding of the surface decorative surface layer material 3 to the hopper 4 is performed with a kneader-extruder 7. Furthermore, the shape of the rear surface of the forming slipper 6 is made to be same as the shape of the side surface of a pressure roll 5.

摘要： PURPOSE:To prevent the generation of flaws and to improve the quality of products by forming a thermal sprayed layer composed of wear resisting material to be prevented the generation of flaws due to the contact of a flange edge of shape into contact with the side of sleeve body. CONSTITUTION:A building up by welding hardened layer 17 composed of the powder of wear resisting high alloy of a high-speed steel materials, etc., is formed on the peripheral part of the sleeve body 12A by a powder plasma building up by welding method. On the other hand, the thermal sprayed layer 19 is made on the annular recessed part formed on the side of the sleeve body 12 by thermal spraying the superior materials to the wear resistance and the seizure resistance. The thermal sprayed layer 19 is provided at the range covering the side part with which the flange edges 15A are brought to contact. Thus, the generation of scratched flaws can be prevented.

摘要： PURPOSE:To prevent the breakage of a self-starter by installing an electricity supply cut-off device into an instruction input circuit and connecting an engine revolution speed detector of an engine and allowing the electricity supply cut-off device to cut off an instruction input circuit when the detected revolution speed becomes over a set revolution speed. CONSTITUTION:An electricity supply cut-off device 10 is formed from a relay 16, comparator, and an FV converter 18, and the relay 16 is connected with a part of an instruction input part circuit 2, and an electromagnetic revolution speed detector 11 is set close to a ring gear 8. Therefore, after the start of an engine E, the revolution speed detector 11 detects the increase of the revolution speed, and when the detected revolution speed becomes over a set revolution speed through the comparison by the comparator 17, the all-time closed contact point 19 of the relay 16 is opened to cut off the instruction input circuit 2, and the electricity supply to a self-starter S is cut off, and the driving force is reduced to zero, and the movement with a starting ring gear 8 is released. Therefore, the breakage of the self-starter S can be prevented, independently of the operation of a main switch 3 after start.

摘要： PURPOSE:To increase the space for the working equipment between front and rear wheels, in a working vehicle whose body is provided with a wheel supporting member through a leaf spring for buffering, by arranging a differential mechanism input shaft upwards, and installing a motive power side rotating member on the input shaft through a rotation transmission shaft which can slide vertically. CONSTITUTION:A differential mechanism 18 for rear wheel is disposed at the center case portion 14a of a wheel supporting member 14, facing its input shaft 19 upwards. A belt pulley 24 which transmits power to the space to the downward output shaft of an engine (not shown here) through a transmission belt is positioned on an input shaft 19 and is installed on a vehicle body 17 with a bearing 25 and a pulley supporter 26 so that it may rotate around the shaft center in the vertical direction of a vehicle. Moreover, the input shaft 19 and the belt pulley 24 are connected to a rotation transmission shaft 32 through universal couplings 28, 29 so that it can slide vertically. It is thus possible to increase the space for working equipment between front and rear wheels.

摘要： PURPOSE:To reduce a head mounting width as compared with that of platen rollers arranged on a straight line and to decrease in size a color printer by disposing the platen rollers on a single circular arc. CONSTITUTION:First - third platen rollers 2A-2C are mounted at 90 deg. at positions passing the circumference of a single circle D indicated by an imaginary line. First - third thermal heads 3A-3C are brought into contact with the rollers 2A-2C though first - third thermal transfer ink ribbons 1A-1C, respectively. When the rollers 2A-2C are driven in a direction of an arrow (b), a sheet 5 to be printed is fed in a direction of an arrow (c). The ribbons 1A-1C are also fed in a direction of an arrow (d) upon feeding of the sheet 5. The heads 3A-3C are driven in response to printing colors. For example, the position of the sheet 5 thermally transferred by the head 3A is repeatedly thermally transferred by the heads 3B, 3C to be completely color printed.
