Abstract: A residue remaining on an object to be cleaned after cleaning is easily detected and observed on the object. Adhesive materials for use in residue confirmation, which are applied in advance to an object to be cleaned for confirmation of a residue remaining on the object after cleaning, are formed by coloring chips produced during cutting work. The adhesive materials are preferably formed by coating and coloring the chips with paint, the paint emitting visible light in an excited state.

Abstract: A feeding device includes a feed base that is horizontally installed, a first driving source and a second driving source, a first saddle, a second saddle, a first propeller shaft, a second propeller shaft, a first transmission device, a second transmission device, and a holding device. The first saddle rotates about a first axis that goes along a vertical direction. The second saddle is disposed at the first saddle. The second saddle rotates about a second axis. The second axis goes along a horizontal direction. The first propeller shaft transmits a torque from the first driving source. The second propeller shaft transmits a torque from the second driving source. The first transmission device transmits a rotation of the first propeller shaft to the first saddle. The second transmission device transmits a rotation of the second propeller shaft to the second saddle. The holding device holds the object.

Abstract: A cleaning method allows reliable cleaning of thread roots of a female screw. A cleaning method for a female screw includes producing a jet of a cleaning liquid from a nozzle in a direction tilted from an axis of the female screw without inserting the nozzle in the female screw, and directing the jet to impinge on a thread of the female screw while rotating the jet about the axis.

Abstract: To provide a hand stocker with a simple structure. A hand stocker housing a hand for attaching on an actuator includes a housing board that houses the hand in a hung state and includes a hanging mechanism hanging the hand on a board surface facing the hand. The hanging mechanism includes: a hooking member that extends in a horizontal direction from the board surface to engage with a hanging portion disposed in the hand; a pressing member that prevents the hand hung on the hooking member from moving to a direction separating from the board surface; and a supporting member that restricts the hand hung on the hooking member from moving to a direction approaching the board surface. The hand is sandwiched between the pressing member and the supporting member and housed.

Abstract: To provide a straightening device that is large in effective sectional area and has high straightening performance. This is a straightening device arranged in a fluid passage for making fluid pass through it that is provided with: a main body having an inflow port arranged in the fluid passage and for flowing the fluid into it, an outflow port for flowing the fluid out of it, and a communication passage for communicating the inflow port with the outflow port; and multiple projections that are arranged in a protruding manner toward a central part of the communication passage from an inner peripheral part and extend along the communication passage, in which the projections are each configured to have a narrower width in the central part than that in an inner peripheral part of the communication passage when seen from a flow direction of the fluid.

Abstract: To provide a cleaning apparatus which is flexibly adaptable to a wide variety of workpieces so as to improve productivity while being suitably adaptable to high-pressure cleaning so as to improve cleaning work efficiency. The cleaning apparatus 10 for cleaning a workpiece W by jetting cleaning liquid from nozzles 22 disposed in a cleaning region E includes: a moving device 70; a feeding device 40 that is disposed facing the cleaning region E to hold and move the workpiece W; a holding device 17 that is disposed on the feeding device 40 to hold the workpiece W; a moving device 70 that movably supports the feeding device 40; and a cover device 14 that shields the moving device 70 from the cleaning region E and allows the feeding device 40 to pass therethrough. The feeding device 40 moves the workpiece W to the cleaning region E for cleaning.

The cleaning apparatus for cleaning a workpiece by jetting cleaning liquid from nozzles disposed in a cleaning region includes: a feeding device that is disposed facing the cleaning region to hold and move the workpiece; a holding device that is disposed on the feeding device to hold the workpiece; a moving device that movably supports the feeding device; and a cover device that shields the moving device from the cleaning region E and allows the feeding device to pass therethrough. The feeding device moves the workpiece W to the cleaning region E for cleaning.

Abstract: To provide a feeding device capable of driving an object with high accuracy while holding the object and controlling its attitude and capable of improving durability by separating a holding device and a driving device from each other, and an object driving device. The feeding device movably disposed through a cover device to face a work region shielded by the cover device, for holding an object, includes: a first rotary saddle that is rotatable about a first axis; a second rotary saddle disposed on the first rotary saddle and rotatable about a second axis perpendicular to the first axis; a holding device that holds the object; a first driving device disposed outward of the cover device with regarding the work region to rotate the first rotary saddle; and second driving device disposed outward of the cover device with respect to the work region to rotate the second rotary saddle.
