Abstract: A self-propelled robot transfer system and a transfer robot used in the system is provided with which, when a reinforcing bar binding self-propelled robot reaches near the end of a reinforcing bar while moving on the reinforcing bar as a track, an operator can move the self-propelled robot in the opposite direction using another reinforcing bar as a new track without having to lift the self-propelled robot by himself, as a result of which, turnaround working of the self-propelled robot can be easily achieved.

Abstract: A binding wire supply system for a reinforcing bar binding machine for supplying binding wire to a reinforcing bar binding machine from the outside of the reinforcing bar binding machine that binds intersections of reinforcing bars with the binding wire, wherein the binding wire supply system includes a reel mounting unit on which a binding wire supply reel, which is arranged close to the reinforcing bar binding machine and supplies the binding wire to the reinforcing bar binding machine, is mounted; a binding wire adapter for introducing the binding wire supplied from the binding wire supply reel into a binding wire accommodating magazine of the reinforcing bar binding machine; and a binding wire insertion guide into which the binding wire is inserted from the reel mounting unit to guide the binding wire to the binding wire adapter.

Abstract: Provided is a vehicle body front structure capable of suppressing load concentration in a collision body and preventing local deformation of the collision body.

Abstract: A vehicle body front structure is provided that can control an amount of absorption of collision load for each portion of a cowl side member while deforming the cowl side member more reliably.

Abstract: A self-propelled robot for rebar binding including wheel units that travel on intersecting rebars; frame units mounted multiply aligned on right and left of the wheel units corresponding to an array interval of the rebars on which the wheel unit travels, binder holding units positioned between a front wheel and rear wheel of the wheel unit and by which rebar binders that bind intersecting rebars are detachably mounted per each wheel unit; driving units each having a binder driving portion that drives the binder holding unit up and down; and a control unit that controls travel motion of the wheel units and binding motion of the rebar binder. The driving units each include a trigger driving pin, and the control unit having a binding control portion that causes the trigger driving pins of the driving units to simultaneously and respectively press the triggers of the rebar binders.

Abstract: A closed deck type cylinder block providing an optimum area ratio of opening at a top deck side, and a method for producing such cylinder block having the reduced area ratio of the opening at a reduced energy cost and with reduced labor, yet exhibiting smooth discharge of waste sand converted from a water jacket core through the opening in spite of the reduced area ratio of the opening. The cylinder block is formed with a plurality of cylinders juxtaposedly arranged to each other and a water jacket portion surrounding the cylinders. An upper end of the water jacket portion is open at a top deck and is partly covered with bridge portions. The opening has an area ratio of from 10 to 30% of a projection area of the water jacket portion at the top deck surface.

Abstract: A metal mold arrangement for producing a closed deck type cylinder block in which a plurality of bridge portions partly cover an open end of a water jacket at a top deck side of the cylinder block. A water jacket die provides a configuration of a water jacket. A plurality of recesses are formed in the water jacket die, and each separate core having a shape complementary to the recess is insetted in each recess. Each separate core has a top deck side end face and a crank case side end face opposite thereto. The two faces are slanted in a direction opposite to each other for serving as drafts. A bottom of each recess is also slanted coincident with the slant of the top deck side end face, and each bridge portion is formed adjacent the bottom of the recess. Upon solidification of a molten metal, the water jacket die is removed from the casted product while each separate core remains in a resultant water jacket.

Abstract: A combination of a device for producing a closed deck type cylinder block and a sand core to be used in the device, the combination being capable of producing the block having high dimensional accuracy and eliminating precise dimensional control to the end face portion of the sand core. The sand core has a configuration identical with a water jacket formed in the engine block. Holding projections extending in an axial direction of a cylinder liner integrally protrude from a slide core of a movable die, and complementary holding bores are formed in the sand core, the bores being open at a top deck end face of the sand core. In one preferred embodiment, the top deck end face of the sand core is of a planner arrangement, and an end face of the slide core is formed with recesses for forming bridge portions therein. Casting is performed while maintaining a surface contact between the planner end face and the end face of the slide core. The contacting areas will become windows of the water jacket.
