Abstract: The amount of carbon dioxide absorbed by plants grown in a field can more accurately be estimated based on environmental information of the field. A plurality of types of mutually-differing environmental information are measured regarding an installation field. For the plurality of types of environmental information, the correspondence relationship between each type of environmental information and a carbon dioxide (CO2) absorption amount is stored. A plurality of CO2 absorption amounts are acquired by referring to the respective correspondence relationship for each type of measured environmental information. The acquired plurality of CO2 absorption amounts are compared with each other and the minimum value thereof is selected as the estimated value. Information regarding the selected estimated value is displayed.

Abstract: In a conventional operating handle for an operating machine, the two ends of a vibration-proof rubber are sandwiched between a handle rod and a grip bar, thereby connecting the handle rod and grip bar. The vibration of the handle rod is absorbed by the torsion of the vibration-proof rubber. As a result, the vibration of the handle rod can only be reduced rather than eliminated. In the present invention, a grip bar is attached rotatably to the upper end of a handle rod so as to be capable of a rocking motion, and the swing shock generated when the grip bar oscillates is absorbed by a stopper rubber provided on the handle rod. Thus the vibration of the grip bar can be absorbed efficiently by the rockable rotatably attached portion and the stopper rubber.

Abstract: A travel control device for vibrating plate compactor which can easily switch the travel direction of a large sized compactor weighing more than 500 kg by a hydraulic pump circuit having a servo valve to supply pressure from outside for switching the travel direction in order to shift the rotational phase of one of the rotors in the vibration generator. The travel control device receives the mechanical return force from the vibration generator at one end thereof in the cylindrical body and is provided at other end with a piston positioned to receive the pressure oil from an outside hydraulic pump, a push rod to operate said piston inserted into the other end of the body from outside, and a spool for servo valve at the side opposite to the side receiving said mechanical return force of said piston to supply the pressure oil from said hydraulic pump by operating said push rod.
