A shaped sheet, comprising: a plurality of protrusions () on one surface side of the shaped sheet formed of fibers; and connecting portions () for being barriers and connecting the protrusions () to one another, wherein the connecting portion () has a fiber density higher than a fiber density of the protrusion ().

Shaped sheet and absorbent article using the same

A stretchable absorbent core () includes a stretchable base sheet (), and a plurality of separate and independent absorbers () disposed at least on one side of the base sheet (). The absorbers () are fixed to the base sheet () through respective fixing points () in such a design that the shape of each absorber is not deformed upon stretch of the base sheet (). The stretchable absorbent core () exhibits stretchability between the fixing points (). It is preferable that the stretchable absorbent core () does not exhibit stretchability at the fixing points ().

Stretchable absorbent core

An absorbent article () includes a topsheet (), a backsheet (), and an absorbent core (). The absorbent core () includes a number of discretely and independently arranged absorbent members () located across a planar direction of the article (). An intermediate sheet () is disposed between the topsheet () and the absorbent core () or between the backsheet () and the absorbent core (). The absorbent members () are fixed to the intermediate sheet (). It is preferable that an absorption rate of physiological saline solution measured by D/W method of each of the topsheet (), the intermediate sheet (), and the absorbent core () satisfies the following relationship: the topsheet ()&#x3c;the intermediate sheet ()&#x3c;the absorbent core ().

Absorbent article

A stretch nonwoven fabriccontains inelastic fibers having a varied thickness along the length and elastic fibers. The nonwoven fabricpreferably includes an elastic fiber layerand a substantially inelastic, inelastic fiber layeron at least one side of the elastic fiber layer. The fibers with a varied thickness along the length are contained in the inelastic fiber layer. The nonwoven fabricis conveniently produced by (a) superposing a web containing low-drawn, inelastic fibers having an elongation of 80% to 800% on at least one side of a web containing elastic fibers, (b) subjecting the webs, while in a non-united state, to through-air technique to obtain a fibrous sheet having the webs united together by thermal bonding the fibers at their intersections, and (c) stretching the fibrous sheet in at least one direction to draw the low-drawn inelastic fibers, followed by releasing the sheet from the stretch.

Stretch nonwoven fabric

Provided is a vibrating section having an ultrasonic transducer of piezoelectric elements and a rear ultrasonic horn and a front ultrasonic horn, the horns being joined to the transducer. The ultrasonic transducer has a consumption power set at 8W or less. The ultrasonic horn has a flat front end surface, the area of the front end surface being set at 0.07 to 1 cm .

Ultrasonic cleaning apparatus

A magnetic recording medium comprising a substrate having an uppermost magnetic layer containing ferromagnetic metal powder and a lower magnetic layer which is adjacent to the uppermost magnetic layer, wherein the uppermost magnetic layer has an average dry thickness of 0.03 to 0.5 .mu.m, the ferromagnetic metal powder in the uppermost magnetic layer is orientated in the horizontal direction of the magnetic recording medium, the magnetic recording medium has a coercive force of 120 kA/m or higher in the horizontal direction thereof, and a ratio of a maximum magnetic susceptibility .chi..sub.max with an external magnetic field applied in the direction perpendicular to the magnetic recording medium to a magnetic susceptibility .chi..sub.8 with an external magnetic field of 8 kA/m applied in the same direction, .chi..sub.max /.chi..sub.8, is 1.3 or higher.
