A scroll fluid machine comprises a fixed scroll, an orbiting scroll and a plurality of self-rotation preventing device for preventing the orbiting scroll from rotating on its own axis. On the rear surface of the orbiting scroll, a reinforcement bearing plate is fixed with a central bolt and an outer circumferential bolt. A follower of the self-rotation preventing device is provided in the reinforcement bearing plate. An oil-supply hole is formed through the reinforcement bearing plate to supply oil to the follower.

In a scroll fluid machine, an orbiting scroll is eccentrically revolved with respect to a stationary scroll so that fluid in a sealed chamber between the stationary and orbiting scrolls may be compressed toward a center. A first magnet is mounted on the stationary scroll and a second magnet is mounted on the orbiting scroll so that the same poles of the first and second scrolls may be opposite to each other thereby preventing the orbiting scroll from pressing the stationary scroll excessively.

An ink-jet recording sheet comprising a support and an ink-absorbable layer is disclosed. The ink-absorbable layer is a void layer containing fine inorganic particles having a dispersion degree of no more than 2 and a hydrophilic binder. The ink-jet recording sheet has a specular gloss specified by JIS Z8741, of at least 20 percent at 60 degrees of the surface of said ink absorbable layer, and exhibits the specular gloss such that 60-degree specular gloss of an ink-recorded part is 3 percent more than that of a nonink-recorded part.

A piezoelectric sound generating element capable of providing flatter and less fluctuated sound pressure frequency characteristics includes a diaphragm that is formed in a circular plate shape with a circular profile. A piezoelectric element is affixed to the side of a bottom wall portion of the diaphragm. The piezoelectric element has an asymmetric octagonal profile including a pair of long side portions opposing each other, a pair of short side portions opposing each other, and four connecting side portions.
摘要:
A scroll fluid machine comprises a housing having a fixed scroll and an orbiting scroll revolved by a driving shaft which is driven by a motor behind the housing. A blowing fan is provided between the orbiting scroll and the motor. Rotation of the fan causes decompression in the housing to allow primary external air to be sucked from the outside into the housing through a primary sucking hole. Secondary external air is introduced from a secondary sucking hole and mixed with the primary external air of the scroll fluid machine to cool the parts of the scroll fluid machine in the housing and/or the motor.
摘要:
A scroll fluid machine comprises a fixed scroll, an orbiting scroll and a self-rotation-preventing device for preventing the orbiting scroll from rotating on its own axis. The self-rotation-preventing device comprises a bearing in a support hole of the orbiting scroll, a crank pin which connects the orbiting scroll to the orbiting scroll, and an adjusting member interposed between the inner circumferential surface of the support hole and the outer circumferential surface of the bearing to correct an error in orbiting motion between the two scrolls.
