摘要:
A blower tube (4) to be connected to a power blower has a tube main body (42) having a distal end portion (42a) diminished in diameter toward its distal end and an attachment (44) to be coupled to the distal end (42a) of the tube main body (42) and including a distal end portion (44a) gradually diminished in diameter toward its distal end. Both these distal end portions (42a, 44a) are each provided three projections at distant position to protrude radially inward toward an axial line of the blower tube (4). The first projections (46) on the tube main body (42) and the second projections (48) on the attachment are positioned offset in phase to align in an alternate order. The blower tube (4) having the projections (46, 48) at the distal end portion can reduce the noise caused by ejection of a high-speed airflow.

A fixing structure for an electrical component includes a heat removing member for removing heat from the electrical component. The heat removing member has a receiving portion for receiving the electrical component. The fixing structure for an electrical component further includes a separation member that is coupled to the electrical component to separate the electrical component from the heat removing member. The separation member is coupled to the heat removing member. The fixing structure for an electrical component includes a soft material member that is accommodated in the receiving portion to contact the receiving portion and the electrical component. Heat of the electrical component is transmitted to the heat removing member via the soft material member.

There is disclosed a vacuum cleaner including a dust separation section which separates air and dust flowing toward an intake port of a motor blower through a connection port of a cleaner main body. The dust separation section includes an air path forming member which performs a separation function. The forming member includes an introductory port, a derivative port, and an opening disposed between these. In the separation function, while dust-containing air flows toward the derivative port from the introductory port, a part of the air is sucked by the motor blower through the opening. Accordingly, the air is separated from the dust which goes straight in the air path forming member with inertia.

The invention provides a surface acoustic wave device and a manufacturing method thereof which enhances reliability and yield. A surface acoustic wave device having a surface acoustic wave element and an electronic component that drive controls the surface acoustic wave element is provided with a first substrate, which has a first connecting terminal having a first hollow component formed therewith including an opening that accommodates an electronic component and electrically connecting to the electronic component formed in the first hollow component, and a second connecting terminal formed in the vicinity of the opening and electrically connecting to the first connecting terminal, a second substrate where one face side is joined to the opening of the first substrate and the surface acoustic wave element is electrically connected to the second connecting terminal on the other face side, and a cap which is joined to the first substrate and has a second hollow component that hermetically seals the surface acoustic wave element.
摘要:
A tensioner acting on and allowing an endless transmission belt, stretched between a driving wheel and driven wheels supported on the body of an internal combustion engine, to run under a constant tension, wherein an oscillating lever supports a tension pulley pressed against a loosening side of the transmission belt and has a base end pivoted on the engine body, and an automatic adjuster connected to a tip end of the lever is supported on a case for a hydraulic pump of the engine. A spacer is interposed between contact portions of the oscillating lever and the engine body, and an outlet of the pump and an oil port of the adjuster are directly communicated. An adjusting screw is provided on the tip end of the oscillating lever and is operatively connected to the upper end of a plunger of the automatic adjuster. An auxiliary spring is further connected to the oscillating lever to assure the transmission belt of the constant tension, and the tension pulley supported on the oscillating lever is pressed against the transmission belt at a location close to the axis of an engine cylinder, that is, almost directly above the driving wheel, to thereby secure a sufficient space for installation of the automatic adjuster outside the pulley.
