    摘要: A power vehicle is equipped with a mower which has cutters, a clipping passage for transporting grass clippings therethrough to one side of the mower, and an impeller accommodated in a housing and mounted on a lateral shaft. The housing has an outer side plate supporting the shaft and positioned closer to the center of the vehicle at its rear end than at its front end and is thereby diminished in the amount of projection. The impeller is driven by a shaft transmission coupled to a belt transmission for driving the cutters and by a belting transmission. The belting transmission includes a pulley coupled to the shaft transmission, a pulley attached to the outer end of the lateral shaft, and a belt reeved around the pulleys and drivingly movable in parallel to the outer side plate of the housing outside thereof.

    摘要: A die casting machine includes vacuum tank 26 and vacuum pump 27 that together evacuate the inside of a mold cavity 40 to a first degree of vacuum, and vacuum tank 21 and vacuum pump 22 that together evacuate the cavity to a second degree of vacuum higher than the first degree of vacuum. The cavity 40 is connected to vacuum tanks 21 and 26 for evacuating the cavity 40 through an evacuation passage 17. When solenoid valves 19 and 24 open and the cavity is evacuated, a powder mold releasing agent is supplied by a powder feeding apparatus 30 into the cavity 40. Filters 20 and 25 each having a filter diameter smaller than a mean grain diameter of the powder mold releasing agent are interposed between the solenoid valves 19, 24 and the vacuum tanks 21, 26, respectively. When the vacuum tanks 21 and 26 evacuate the cavity 40, filters 20 and 25 capture the major proportion of the powder mold releasing agent, and the occurrence of trouble in the vacuum tanks, etc, can be prevented.

    摘要: A digital audio tape recorder is adapted for recording non-music signals such as, typically, those representative of measurements being made in real time by one or more instruments or meters, together with brief vocal commentary on the measurements and/or with the date and time at which the measurements are made. If the measurements of two instruments or meters are to be recorded simultaneously, the two measurements signals as well as the vocal commentary signal are first digitized. A multiplexing circuit combines the first measurements signal and the commentary signal into a first series of composite data words, and the second measurements signal and a digital time signal into a second series of composite data words. The bits of each composite data word are apportioned between the first measurements signal and the commentary signal, and between the second measurements signal and the time signal, according to their expected relative amounts to be recorded. The two series of composite data words are transmitted by time division multiplexing to the record/reproduce circuit of the digital audio tape recorder, for interleaved recording on the tape just like stereophonic audio signals. Provisions may be made for reproduction of the non-music signals recorded.

    摘要: A position control valve provided for controlling a first hydraulic unit is also operable to control a second hydraulic unit. The apparatus comprises the first hydraulic unit for raising and lowering a primary working implement, the second hydraulic unit for raising and lowering a secondary working implement, the control valve for controlling the first hydraulic unit, and a feedback mechanism for returning the control valve to its neutral position for every position of a control lever in operative relation to the upward or downward movement of the primary working implement. A guide plate for the control lever for operating the control valve provides a second operation range for the secondary working implement having a neutral position corresponding to a maximum lift position for the primary working implement. Elastic regulating means is mounted on the guide plate for the second operation range to set the control lever in position. The control lever is automatically and accurately returnable to the neutral position when operated against the elastic means and thereafter released from the hand.

    摘要: A servo motor controller is provided with a motor control section for controlling a servo motor provided with a brake. The motor control section includes a speed command portion for outputting a speed command to increase or reduce the rotation of the servo motor, and a brake switching portion for outputting switch command for a braking circuit to switch the brake, wherein the brake is activated during speed reduction of the servo motor by the speed command portion, whereby a rotation of the servo motor is stopped. The motor control section further includes a monitoring portion for monitoring whether or not the decelerating torque of the servo motor during speed reduction exceeds a set value that has been set equal to or lower than a maximum allowable torque of the servo motor in the motor control section.
