Abstract: To suppress static leakage in a seal device, a seal lip is configured for sliding contact with a seal flange that includes a thread groove exerting a fluid pumping action at a time of shaft rotation. The seal device prevents sealing fluid on the inner-machine side from leaking to the outer-machine side between a housing and a rotating shaft inserted into a shaft hole on the housing. The seal lip is attached to the inner periphery of the shaft hole and the seal flange is attached to the outer periphery of the rotating shaft. A sliding area in the seal flange in sliding contact with the seal lip is a flat surface with no thread grooves, and has an outer peripheral side area and an inner peripheral side area, which each have a thread groove exerting a fluid pumping action when the rotating shaft rotates.

Abstract: Static leakage is suppressed in a sealing device, where a sealing lip slidably makes contacts with a sealing flange, in which a thread groove exhibits fluid pumping action during rotation. Sealing device performs sealing between a housing and a rotating shaft inserted into a shaft hole in the housing to prevent sealed fluid on a machine inner side from leaking to an outer side. A sealing lip mounted on an inner periphery of the shaft hole slidably makes contact with the sealing flange mounted on an outer periphery of the rotating shaft. The thread groove intersects an edge of the sealing lip. An inner peripheral tube portion is provided on an attachment ring that holds the sealing lip. An inner peripheral lip that slidably makes contact with the inner peripheral tube portion is provided on the sealing flange side on the inner peripheral side of the thread groove.

Abstract: The invention relates to a composition for taking dietary fibers, which comprises 1 to 50% by weight, on the basis of the whole composition, of dietary fibers composed of water-soluble and hardly fermentable dietary fiber and water-soluble and fermentable dietary fiber, wherein the water-soluble and fermentable dietary fiber is contained in a proportion of 0.1 to 3 parts by weight per part by weight of the water-soluble and hardly fermentable dietary fiber. The composition remarkably ameliorates not only bowel movement frequency but also full consciousness, feeling of unsatisfied defecation, etc. and is hence useful as food for ameliorating bowel movement.

Abstract: In a universal joint boot including a bellows part, a ring-shaped mounting part that is formed at one end of the bellows part and into which a cup for receiving one member of two members moving relatively to each other is inserted; and a seal that is formed toward the peripheral direction of the inner peripheral surface of the mounting part to which the cup is mounted, the inner peripheral surface has protrusions protruding toward the axial center of the ring-shaped mounting part and the height of the seal lip becomes lower from the bottom of the protrusion to a peak and width of the seal lip becomes wider from the bottom of the protrusion to the peak, whereby sealing performance can be improved.

Abstract: A universal joint boot having a boot body including a bellows part and an opening portion which is formed in one end of the bellows part and into which a case for receiving one member of two members moving relatively to each other is inserted. An annular adaptor is mounted on the inner peripheral surface of the opening portion and has an outer peripheral surface formed nearly in the same shape as the inner peripheral surface. The adaptor has a fixing portion that is pressed by the inner peripheral surface of the opening portion of the boot body, thereby being fixed to the case. A reversing portion is located opposite to the fixing portion with the opening portion between them and sandwiches the opening portion together with the fixing portion. A folding portion is located where the reversing portion is folded back to the outside. Hence, the universal joint boot can be easily assembled.

Abstract: In a universal joint boot 1 including a bellows part 10, a ring-shaped mounting part 20 that is formed at one end of the bellows part 10 and into which a cup 40 for receiving one member of two members moving relatively to each other is inserted; and a seal lip 24 that is formed toward the peripheral direction of the inner peripheral surface 22 of the mounting part 20 to which the cup 40 is mounted, the inner peripheral surface 22 has protrusions 23 protruding toward the axial center of the ring-shaped mounting part 20 and the height of the seal lip 24 becomes lower from the bottom 23a of the protrusion 23 to a peak 23b and width of the seal lip 24 becomes wider from the bottom 23a of the protrusion 23 to the peak 23b, whereby sealing performance can be improved.

Abstract: There is provided a universal joint boot 10 having: a boot body 1 including a bellows part and an opening portion 2 which is formed in one end of the bellows part and into which a case for receiving one member of two members moving relatively to each other is inserted; and an annular adaptor 20 that is mounted on the inner peripheral surface of the opening portion 2 and has an outer peripheral surface formed nearly in the same shape as the inner peripheral surface, wherein the adaptor 20 has: a fixing portion 24 that is pressed by the inner peripheral surface of the opening portion 2 of the boot body 1, thereby being fixed to the case; a reversing portion 26 that is located opposite to the fixing portion with the opening portion 2 between them and sandwiches the opening portion 2 together with the fixing portion; and a folding portion 25 where the reversing portion 26 is folded back to the outside. Hence, the universal joint boot 10 can be easily assembled.

Abstract: A steam-generating unit that is applied to the skin or the mucous membranes has a steam-generating part that employs chemical energy, and the surface applied to the skin or mucous membranes is made from a moisture-permeable sheet. The temperature of the steam generated by the steam-generating part and released from the surface of the steam-generating unit is kept to 50° C. or lower. Steam that is as safe as that from a steam towel can be easily and continuously supplied to the skin and mucous membranes by this steam-generating unit.
