Abstract: The present disclosure relates to a hybrid working vehicle which determines the change of load by using a displacement of a flyweight or flyball in a governor, and controls a motor-generator according to the change of load, and a control method thereof. The hybrid working vehicle detects the change of load based on the displacement of the flyweight or flyball measured by a displacement measuring device, operates a motor-generator as a motor to supplement the power in a case where the load increases, and operates the motor-generator as an electric generator to collect energy in a case where the load decreases.

Abstract: Provided is a tractor having a hydraulic lifting apparatus, wherein, assuming that a lift of the hydraulic lifting apparatus is P (N), a discharge flow rate of a hydraulic pump is Q (m3/s), a horsepower of an engine is H (N·m/s), an axial distance is L (m), and a total weight of the tractor is W (N), the following Equation is satisfied: 100×H/Q<P<L×W/1.5.

Abstract: This disclosure relates to an automatic transmission, and more particularly, to an automatic transmission which alleviates a gear shifting shock generated during a forward/reverse gear shifting operation by controlling a clutch actuator to operate a clutch and interrupting a transmission of power generated from an engine during the forward/reverse gear shifting operation of a vehicle.

Abstract: A method of construction of a damp-proof basement includes disposing a water-permeable palette layer on a bottom surface of the interior of the basement and spaced from an outer wall of the basement, disposing a water-impermeable vent layer over the palette layer, disposing a reinforced-concrete slab on the vent layer and spaced from the outer wall, and disposing an inner wall at a periphery of the concrete slab and spaced from the outer wall. A damp-proof basement construction includes a water-permeable palette layer, disposed on a bottom surface of the interior of the basement, spaced from an outer wall of the basement. A water-impermeable vent layer is disposed over the palette layer. A reinforced-concrete slab is disposed on the vent layer, spaced from the outer wall. An inner wall is disposed at a periphery of the concrete slab, spaced from the outer wall.

Abstract: A damp-proof insulation brick cover having an empty space at the bottom of the dampproof brick cover formed of rectangular hexahedrons, formed as a unit including a pair of side walls, a pair of longitudinal walls, and an upper panel part. At certain intervals, a plurality of protruding parts are formed under the whole upper panel, wherein an insulation space is formed between said upper panel and upper part of said brick when the brick is inserted into the inner space of the brick cover.Slanted protrusions are installed between vertical protrusions at an upper part of both ends of the longitudinal walls of the brick covers, and a slanted protrusion is formed in one of said longitudinal walls, at the same height as the side wall slanted protrusion.When applied to the bottom part of a protection wall, the floor of which has lots of water permeating from underground, the brick cover prevents capillary action of water in the walls.
