摘要:
A liquid crystal display device includes a pair of substrates arranged to face each other, and electrodes respectively arranged on inner sides of the substrates, define a plurality of pixels in a display region. A sealing frame surrounds an outer side of the display region between the pair of substrates, and joins the substrates with a predetermined gap in which a liquid crystal layer is provided. A plurality of spacer elements are dispersed between the substrates and have a diameter that restricts a length of the gap between the substrates. A support layer is provided in a clearance between the display region and the sealing frame between the pair of substrates, and comes into contact with those of the spacer elements which are positioned close to the sealing frame, to support these spacer elements to prevent a deformation of the substrate.

An electric vacuum cleaner includes a nozzle assembly 5 including: a base member 6; a movable member 7 inversely rotatably attached to the base member 6 and having one surface formed with a suction opening 20; and a covering member 8 movably attached to the base member 6. Holding members 22 for holding a cleaning sheet 21 are formed on the other surface of the movable member 7. When the one surface of the movable member 7 faces a floor surface and the other surface thereof is covered by the covering member 8, the electric vacuum cleaner can pick up filth through the suction opening 20. When the movable member 7 is rotated inversely so that the cleaning sheet 21 faces the floor surface, the electric vacuum cleaner can catch the filth by the cleaning sheet 21 and pick up the relatively large filth via a communicating path 34 formed in between the movable member 7 and the covering member 8, and the suction opening 20 connected to the communicating path 34.

The lip-type seal of the present invention is a lip-type seal with which the outer periphery of a rotational shaft (S) supported by a predetermined housing (H) is sealed. This lip-type seal includes a seal ring (20) made of an elastic material so as to have an annular fitted part (21) that is fitted to the housing and a lip part (23) that extends from the fitted part inwardly in a radial direction in the shape of a substantially conical ring and that is brought into contact with the shaft, and a support ring (30) including an annular joint part joined to the fitted part and an annular supporting part (33) that defines a hole (30a) through which the shaft passes, that extends from a side of the joint part to a halfway area of the lip part, and that supports the lip part from the inside in the radial direction. In this lip-type seal, the lip part (23) is tapered in cross section from an area from which noncontact with the supporting part (33) starts toward an end thereof. Therefore, wear is reduced in a high-pressure environment, and durability is improved while securing a desired sealing capability.

A cyclonic vacuum cleaner with simple structure, low airflow leakage, excellent maintainability, and less possibility of littering a floor in the case of dumping dusts or care of the cleaner. A cyclonic portion 14 of an approximately cylindrical shape, having a bottom, an introducing portion 15 for introducing dust-laden airflow to the cyclonic portion 14, and a reinforcing rib 35 provided on a lowermost end of the dust-collecting portion 11 for allowing it to stand on end, are formed into a one-piece structure. Thus, the structure from the introducing portion 15 to the cyclonic portion 14 can be simplified and the possibility of airflow leakage can be reduced. Also, maintenance of the cyclonic portion 14 and the introducing portion 15 can be easily performed through the detachment of the dust-collecting portion 11 together with the introducing portion 15. Further, a floor is less likely to be littered with dusts collected within the cyclonic portion 14 by allowing the dust-collecting portion 11 to stand on end with the help of the reinforcing rib 35.

摘要:
First pumping threads are formed on an inner circumferential surface of the seal lip portion of an elastomer lip member. The first pumping threads generate a pumping action in a leakage direction when a shaft rotates. A first resin lip member is arranged at a rear side of the elastomer lip member. Second pumping threads generate a pumping action in a direction opposite to the leakage direction when the shaft rotates. The second pumping threads are formed from an inner circumferential surface of a seal lip portion of the first resin lip member to a rear portion of a bent portion thereof. A second resin lip member is arranged at a rear side of the first resin lip member and has a surface sliding on the shaft, which is formed smoothly.
