Abstract:
A liquid-discharging head includes a substrate; a flow passage wall-forming layer bonded to the substrate so as to form a flow passage for liquid between the substrate and the flow passage wall-forming layer, the flow passage communicating with a discharge port configured to discharge the liquid; an element configured to generate energy used for discharging the liquid from the discharge port and provided on the flow passage wall-forming layer; a metal layer provided with the discharge port so as to correspond to the element; and a projecting portion made of a metal and extending from the metal layer through the flow passage wall-forming layer and projecting in the direction of the substrate.
Abstract:
A flexible tube includes a bellows tube, an interlock tube placed inside the bellows tube, and upstream-side and downstream-side joint pipes coupled to opposite ends of the bellows tube. Diameters of fixing end portions located at opposite ends of the interlock tube are made larger than a diameter at a middle portion of the interlock tube, extension portions of the upstream-side and downstream-side joint pipes are fitted and fixed to inner peripheral surfaces of the fixing end portions of the interlock tube, and a depth of each of valley portions of a bellows portion of the bellows tube located over the fixing end portions is smaller than a depth of other valley portions of the bellows portion. Accordingly, it is possible to achieve the downsizing of the flexible tube that is connected to an exhaust system being continuous with an engine to dampen vibrations in the axial direction of the exhaust system.
Abstract:
A method comprising constraining a circumference of a blank of a Cu—Mo alloy and one of surfaces to be worked with the use of a die, and using a working punch or a counter punch to apply working pressures to the other of the surfaces to be worked, thereby obtaining a cup-shaped body.
Abstract:
The invention provides a heat sink board and a manufacturing method thereof, which can realize a high product accuracy and superior productivity. To that end, a second heat sink (3) having a smaller linear expansion coefficient than that of a first heat sink (2) is bonded to the first heat sink (2) to form a heat sink board. The second heat sink (3) is fitted to the first heat sink (2), and a material of the first heat sink (2) in the vicinity of a boundary between the fitted heat sinks is plastically deformed for close adhesion to the second heat sink (3). Such a forming method makes bonding between the first and second heat sinks possible at room temperature, and the heat sink board made of a composite member having a high flat-surface accuracy can be easily and reliably obtained.
