Abstract: A nitrogen gas tank, a rotary pump and a mechanical booster pump are connected to a bonding vessel that constitutes a bonding apparatus for carrying out diffusion bonding, the apparatus further comprising a pressure sensor. A nitrogen gas atmosphere is formed inside the bonding vessel, and under control operations of a control circuit, a nitrogen introduction rate is controlled so that a pressure is substantially fixed at a predetermined pressure between 3-105 Pa. At such a state, under the action of a rod of a hydraulic cylinder, a second electrode is brought into proximity with a first electrode, so that ultimately, a first object to be bonded and a second object to be bonded on the first electrode are pressed. Further, current is applied through the first electrode and the second electrode with respect to the first object to be bonded and the second object to be bonded.

Abstract: The multiblade impeller of the present invention comprises a main plate, a side plate having a suction port at a center thereof, and a large number of blades provided between the main plate and the side plate and extend in the radial direction in an arc form. The main plate and the side plate each have a large number of ridge portions, each extending in the radial direction in an arc form so as to coincide with the shape of the blade extending in the radial direction in an arc form. End portions of the blades are inserted in grooves formed inside the ridge portions of the main plate and the side plate and are fixed to the ridge portions by being bent.

Abstract: A fluid flow passage structure and a manufacturing method therefor are provided, in which fluid flow passages can be easily produced employing a simple structure and process, while also being suitable for reducing the weight thereof. Wire members having a predetermined pattern are disposed between a first block member and a second block member. Airtight and fluidtight hermetic fluid flow passages are formed between such members, by forming the first block member, the second block member, and the wire members together as an integral structure.

Abstract: The motor of the invention is an outer rotor type motor, and a rotor includes a cylindrical rotor frame that is opened at one end thereof in an axial direction, and a hollow cylindrical magnet attached to an inner periphery of the rotor frame. The magnet has a joining portion joined to an inside cylindrical portion of the rotor frame, and a protruding portion that further protrudes in the axial direction from one end, the outer diameter of the protruding portion is larger than the inner diameter of the rotor frame, and the joining portion is directly brought into close contact with a portion ranging from the one end to at least a portion of the inside cylindrical portion.

Abstract: A laminated structure is formed by stacking a first block member, an intermediate member, and a second block member together in this order, and then mutually joining each of the members. Further, by setting the elastic constant of the intermediate member to be greater than the elastic constants of the first block member and the second block member, deformation of grooves, which are formed in the first block member, is minimized.
