摘要:
The invention relates to a drill chuck which has a drilling needle receptacle device for removable receiving of a drilling needle (1), a hollow cylindrical magnetic holder for the drilling needle receptacle device and a coupling device for torque transfer from a drive device to the drilling needle receptacle device. The drilling needle receptacle device, in which a drilling needle (1) having a flattened end section (1') can be received, has a receptacle element (7), at least two clamping bodies (10) and a clamping insert (6). The receptacle element (7) has at least one cylindrical section (72) having a recess (71) and the clamping insert (6) has counter-molded bodies (61) which supplement the clamping bodies (10) and which extend away from a stop disc (62). The stop disc (62) contacts a face of the cylindrical section (72) and has a lead-through opening (63) for the drilling needle (1). The counter-molded body (61) and the clamping bodies (10) are designed in respect of the dimensions and shape thereof for arrangement in the recess (71) and for clamping receiving of the flattened end section (1') of the drilling needle (1) between the clamping bodies (10) and the counter-molded bodies (61). The invention further relates to a drilling needle and to a drilling needle-drill chuck assembly.

A moil guide having a sleeve that has an opening adapted to receive at least a portion of a linerbolt. The moil guide also has a magnetic attachment device attached to the sleeve. The magnetic attachment device is operable to selectively generate a magnetic field. The magnetic attachment device is operable to selectively generate the magnetic field to removably attach the moil guide to a metal surface.
摘要:
First, a plate 22, a cooling plate 28, and a double-sided adhesive bonding sheet 32 composed of an acrylic resin are prepared. Next, the bonding sheet 32 is applied onto the upper surface of the cooling plate 28. Subsequently, the cooling plate 28 to which the bonding sheet 32 is applied is placed in a vacuum dryer. The pressure in the dryer is reduced to 2,000 Pa or less, and a pre-bake treatment is conducted in this state. The pre-bake treatment is conducted at 120°C to 130°C for 15 to 40 hours, and natural cooling is then conducted in a vacuum. After the pre-bake treatment, the plate 22 is stacked on the bonding sheet 32 so that the lower surface of the plate 22 is aligned with the upper surface of the bonding sheet 32, which is applied onto the cooling plate 28. The resulting stacked body is placed in a heat-resistant resin bag, and is then placed in an autoclave. The stacked body and the heat-resistant resin bag containing the stacked body are treated together for several hours under pressure and heat. Thus, an electrostatic chuck 20 is obtained.
摘要:
A feeding structure of an electrostatic chuck comprising a lower insulation layer, an electrode layer and a surface insulation dielectric layer formed sequentially on the upper surface side of a metal substrate with the lower insulation layer closest to the metal substrate, in which the lower insulation layer, the electrode layer and the surface insulation dielectric layer are not cracked easily. The feeding structure of an electrostatic chuck is constituted of a through hole penetrating between the upper and lower surfaces of the metal substrate, a feeding terminal arranged in the through hole and feeding a voltage supplied from the lower surface side of the metal substrate to the electrode layer formed on the upper surface side, and an insulation holding member formed of an electric insulating material in order to insulate the inner wall of the through hole from the feeding terminal and holding the feeding terminal, wherein the feeding terminal has a feeding side end projecting to the upper surface side of the metal substrate, and the tip of the feeding side end is located closer to the electrode layer side than the interface between the electrode layer and the lower insulation layer and below the interface between the electrode layer and the surface insulation dielectric layer.
