A method applying a thermal barrier coating to a metal substrate, or for repairing a thermal barrier coating previously applied by physical vapor deposition to an underlying aluminide diffusion coating that overlays the metal substrate. The aluminide diffusion coating is treated to make it more receptive to adherence of a plasma spray-applied overlay alloy bond coat layer. An overlay alloy bond coat material is then plasma sprayed on the treated aluminide diffusion coating to form an overlay alloy bond coat layer. A ceramic thermal barrier coating material is plasma sprayed on the overlay alloy bond coat layer to form the thermal barrier coating. In the repair embodiment of this method, the physical vapor deposition-applied thermal barrier coating is initially removed from the underlying aluminide diffusion coating.

Audio apparatus (30) comprising a piezoelectric transducer (44) and coupling means (54) for coupling the transducer to a user's pinna (32) whereby the transducer excites vibration in the pinna (32) to cause it to transmit an acoustic signal from the transducer (44) to a user's inner ear, characterised in that the transducer is embedded in a casing (42) of relatively soft material and the casing (42) is mounted to a housing (34) of relatively hard material such that a cavity (48) is defined between the casing (42) and housing (34). A method of designing audio apparatus comprising mechanically coupling a piezoelectric transducer to a user's pinna and driving the transducer so that the transducer excites vibration in the pinna to cause it to transmit an acoustic signal from the transducer to a user's inner ear, characterised by embedding the transducer in a casing of relatively soft material and by mounting the casing to protective housing of relatively hard material such that a cavity is defined between the casing and housing.

A lacrosse head comprising a frame, a pocket attached to the frame, and at least one energy absorbing element engaging the frame to absorb energy from an impact to the pocket. Preferably, the frame, which includes a scoop, a throat, and sidewalls, includes energy absorbing elements positioned proximate to the throat and along the sidewalls of the frame. The energy absorbing elements can be positioned on an external surface of the perimeter of the frame. The frame includes pocket attachment apertures and the energy absorbing elements include apertures, wherein the apertures on the energy absorbing elements are substantially aligned with the pocket attachment apertures to secure the energy absorbing elements to the frame.

By using a stacked gate transistor including a floating gate in a limiter, a threshold voltage Vth of the stacked gate transistor can be corrected by controlling the amount of charge accumulated in the floating gate of the stacked gate transistor even in the case where there are variations in the threshold voltage Vth of the stacked gate transistor.

The invention describes extruded member systems to which a photovoltaic device is secured to an architectural surface.

A beard trimmer having a handle, a motor and a head portion. The head portion comprises at least a first long hair cutter unit for trimming hair that is provided with a first outer cutter and a first inner cutter.

A seal assembly and method for the manufacture thereof is provided. The seal assembly provides a dynamic fluid seal between a housing having a bore and a shaft having an outer running surface rotating within the bore. The seal assembly comprises a rigid carrier for supporting the seal assembly within the bore of the housing. A flexible member is mounted to the rigid carrier. The flexible member is formed from an elastomeric material that allows the flexible member to flex during use. A sealing element is retained by the flexible member about the outer running surface. The sealing element is formed from a non-polytetrafluoroethylene bearing grade plastic material having a hardness relatively greater than a hardness of the elastomeric material of the flexible member. The sealing element moves with the flexible member as the flexible member flexes. The sealing element extends along the outer running surface in a plurality of helically wound convolutions.

A plurality of working blocks (A, B) are connected by rails (18). A branched transporting mechanism (100) is disposed at the intersections of the rails (18). A transportation vehicle (300) of non-self-propelled type moves on the rails (18) by the driving power of a wire (20). A placement table (450) is positioned in the vicinity of the working blocks (A, B). The placement table (450) moves up and down with a workpiece placed thereon between the transportation vehicle (300) and the working blocks (A, B). Transfer of work is effected by moving the placement table (450) up and down, and adjusting the height of the placement table (450) to the height of the transportation vehicle (300) or to the height of the working blocks (A, B). Further, the transportation vehicle (300) has a wire gripping mechanism (350) for gripping the wire (20), and workpiece placement plates (326a, 326b) for placing the workpiece thereon.
