The present invention relates to an absorbent material that can be used as an absorbent core in absorbent articles such as sanitary napkins, pantiliners, incontinence products, disposable diapers, etc. The material of the present invention is a nonwoven sheet, consisting of cellulosic fibers, optionally superabsorbent polymeric material, containing no binders, latexes, etc, relying on hydrogen bonding to produce the necessary structure. The material contains density gradients which direct fluid into the material and distribute it providing more effective fluid transport and efficient utilization of storage capacity. The material consists of two regions. In the first region, the material has a low-density stratum adjacent to one surface, overlaying at least one higher density stratum adjacent to the opposite surface of the sheet. These strata create a density gradient in the thickness direction (Z-direction) of the sheet. The second region consists of a fluid distribution structure that has a higher density than at least the lower density of the strata comprising the first region. The fluid distribution structure is in direct fluid communication with the adjacent strata in the first region, along their boundaries.

A lens barren assembly for a camera is disclosed. The lens barrel assembly comprises a lens barrel, at least one optical element disposed within the lens barrel, and an actuator configured to move the optical element. The actuator can be disposed entirely or partially within the lens barrel. The actuator can be a MEMS actuator, such as a MEMS actuator that is formed at least partially of silicon. The optical element can be a lens.

There is provided a dust compressing apparatus for a dust collecting unit of a vacuum cleaner. In the dust compressing apparatus, a compartment plate divides an inner space of a dust collection container into an upper foreign substance separating compartment and a lower foreign substance storing compartment, and a branching unit guides airflow. The branching unit includes a motor connection passage directed to a motor generating a negative pressure, a dust collection passage directed to the foreign substance separating compartment, and a compression passage directed to the foreign substance storing compartment. A flow passage control unit controls connections between the passages of the branching unit. A compression unit compresses foreign substances stored in the foreign substance storing compartment by moving the compartment plate to the foreign substance storing compartment using the negative pressure transmitted through the compression passage.

A cover assembly for covering a pivot of an electronic device is disclosed. The pivot connects a first component and a second component of the electronic device. The cover assembly is disposed at one side of the pivot, and the cover assembly includes a first covering element and a second covering element. A first end of the first covering element is connected to the first component, and a second end of the first covering element includes a first limit part. A first end of the second covering element is connected to the second component, and a second end of the second covering element includes a second limit part. The first covering element is overlapped with the second covering element. When the pivot rotates, the first limit part and the second limit part move correspondingly.

An X-ray thin film inspection apparatus including a sample table on which an inspection target such as a product wafer or the like is mounted, a positioning mechanism for moving the sample table, a goniometer having first and second swing arms, at least one X-ray irradiation unit that are mounted on the first swing arm and containing an X-ray tube and an X-ray optical element in a shield tube, an X-ray detector mounted on a second swing arm, and an optical camera for subjecting the inspection target disposed on the sample table to pattern recognition.

An accumulation conveyor system for supporting and moving a plurality of objects. The conveyor system is divided into a plurality of zones wherein each zone includes a top and bottom conveying surface and wherein a space is defined between the top and bottom surfaces. Each zone also includes its own motor positioned external to the space between the conveying surfaces and coupled to the conveying surfaces via a non-slip connection. A control system is connected to the motor and controls the power to the motor so that the conveying surfaces in each zone can be moved independently. Whenever a sensor detects an empty downstream zone, it signals the control system of the upstream zone to power the motor and move the object to fill the empty zone. The control system may also be configured to allow a soft start wherein motor speed is increased gradually.

A connector assembly includes a mating male and female element and further includes a retainer made from large high friction material, a generally annular sealing element and an anti-rotation mechanism for restraining the relative rotation between the male element and female element. The female element includes a housing formed with an axial bore for receive an insert end portion of the male element at a receipt end portion, the receipt end portion having an enlarged diameter internal bore potion adapt to receive the retainer fore locking a radially enlarged annular projection on the insert end portion of the male element, which is secured the receipt end portion of the female element.

A goggle clip (10) that may be used to rotatably or pivotally secure a strap (12) to a goggle (14) with a concealed hinge. The clip (10) broadly comprises a main body (24) located outside a shroud (20) of the goggle (14) and secured to the strap (12), an axle (26) located inside the shroud (20), and a forwardly extending skirt (30) that substantially conforms to the shroud (20). The skirt (30) preferably maintains close proximity to the shroud (20) during rotation of the clip (10). Thus, the skirt (30) forms an aerodynamic seal with the shroud (20), thereby diverting airflow away from the hinge and preventing wind, dust, dirt, and other contaminants from interfering with the hinge's operation. Furthermore, the skirt (30) and the location of the axle (26) conceal the hinge, thereby providing a more aesthetically appealing goggle (14).

An optical semiconductor device encapsulated with a silicone resin that suffers no discoloration of the lead and exhibits excellent thermal shock resistance. The optical semiconductor device includes an optical semiconductor element and a cured product of a silicone resin composition that encapsulates the optical semiconductor element, wherein the amount of (ΦSiO_3/2) units (wherein Φ represents a phenyl group) within the cured product, determined by solid ²⁹Si-DD/MAS analysis, is within a range from 0.13 mol/100 g to 0.37 mol/100 g.

According to the present invention, in a carrying system comprising a carrying vehicle and a manufacturing apparatus the interior of which is kept cleaner than a surrounding environment, manufactured articles to be transferred are prevented from being contaminated by foreign matter or the like attached to transfer ports. A carrying vehicle includes a running unit 14 that runs along a predetermined carrying path, a cleaning unit 12 that supplies cleaned air, a housing section 13 to which the cleaned air is supplied and in which manufactured articles are housed, a transfer port 11 which is formed in a side of a housing and through which a manufactured article is loaded into or unloaded from the housing section 13, and an air injecting section 19A that blows out air toward the transfer port 11.
