A center pipe is used in a plasma torch including a base portion and an electrode to supply cooling water into the electrode. The center pipe includes a pipe body and a contact piece. The pipe body has a tube-like shape with a cooling water channel therein. The pipe body is electrically conductive and configured to be electrically connected to an external power source via the base portion. The contact piece is arranged radially outside the pipe body at an intermediate position between a base end surface and a tip end surface of the pipe body. The contact piece is electrically conductive and energizes the electrode through contact with an internal circumferential surface of the electrode. The base end surface is disposed outside the electrode when the center pipe is inserted into the electrode. The pipe body is configured to be electrically connected to the electrode via the contact piece.

A replacement part unit for a plasma torch includes an electrode, an insulation guide, and a nozzle. The insulation guide includes a hole into which the electrode is inserted. The insulation guide is coupled to the electrode by press-fitting or adhesion. The nozzle includes a hole into which the insulation guide is inserted. The nozzle is coupled to the insulation guide by press-fitting or adhesion.

Replacement part unit for plasma torch, electrode, insulating guide, and nozzle

A resin insulation guide is used in a plasma torch including an electrode and a nozzle into which the electrode is inserted. The insulation guide is used to couple the electrode and the nozzle, and includes a first internal circumferential surface formed on an inside of the insulation guide, a second internal circumferential surface formed on the inside of the insulation guide, a communication channel, and a heat resistant coating formed on the first internal circumferential surface. The second internal circumferential surface has an inner diameter smaller than an inner diameter of the first internal circumferential surface. The communication channel communicates a space inside the first internal circumferential surface to an outside of the insulation guide, and extends in a direction inclined with respect to an axial direction of the insulation guide.

A center pipe is used in a plasma torch for plasma cutting including a base portion and an electrode. The center pipe is inserted into the electrode and supplies cooling water into the electrode. The center pipe includes a pipe body and a contact piece. The pipe body is electrically connected to an electrical power source outside of the plasma torch via the base portion. The pipe body includes a cooling water channel therein. The pipe body is formed with an electrically conductive body. The contact piece is provided on the external circumferential surface of the pipe body and energizes the electrode through contact with the internal circumferential surface of the electrode. The contact piece has elasticity to produce a counterforce when pressed in the radial direction of the pipe body. The contact piece is formed with an electrically conductive body.

A plurality of cutout members are cut out from a plate blank by a plasma arc generated from a plasma torch by a method including a piercing step and a cutting step. In the piercing step, an aperture is formed on an outer peripheral side of a cutout member by maintaining the plasma torch at a first height from the plate blank on the outer peripheral side of the cutout member while the plasma arc is generated from the plasma torch and by moving the plasma torch relative to the plate blank in a horizontal direction. In the cutting step, a continuous cutting groove is formed along an outer contour of the cutout member by setting the plasma torch at a second height lower than the first height and by moving the plasma torch in the horizontal direction along an incision part and a processing line continuing to the incision part.

According to one embodiment, a display apparatus includes an image data generation unit configured to generate image data and an image projection unit configured to project a light flux including an image toward a human riding in a vehicle. The image is based on the image data. The image data generation unit is configured to generate the image data relating to the image including a first display object indicating a travel direction of the vehicle at a travel direction change point when a distance between the travel direction change point and the vehicle is a first distance. The image data generation unit is configured to generate the image data relating to the image including a second display object displayed to correspond to a position of the travel direction change point when the distance is a second distance shorter than the first distance.

Display apparatus, display method, and vehicle

A die cushion device includes a cushion pad, a support section, a servomotor, and a shock absorber device. The support section supports the cushion pad. The servomotor raises and lowers the support section for raising and lowering the cushion pad. The shock absorber device includes a damping section and relieves shock between the cushion pad and the support section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section.
