A lower sash made of resin comprising a scraper for suppressing or preventing entry of the foreign substances itself as means for suppressing or preventing generation of noise is provided. The lower sash made of resin comprising a substantially channel-structured frame extending along a direction in which a window glass ascends and descends, the frame comprising wings provided upright on both sides of a base, and glass guides provided in opposition to the wings each other, and further comprising...

A man-made floating island includes platform units above the water with vertical members extending downwardly therefrom on which movable floats are mounted which move in response to wave action. Motion of the floats operates air compressors and the resulting compressed air is either converted to transmissible energy or stored in reservoirs for future use. Wave amplifiers may be disposed beneath the movable floats.

A polysaccharide polymer is disclosed which is a better viscosifier of water than xanthan gum. The polysaccharide polymer and its non-acetylated form, are comprised of glucose and mannose moieties in a ratio of about 2:1. The invention also discloses Xanthomonas mutants which produce the polysaccharide polymer but which do not produce xanthan gum. Methods of preparing the polysaccharide polymers and of their use are also described.

Improved fabrics are produced by weaving and using relatively uniform elongated hollow monofilament bristles which partially collapse during weaving to form a partially flattened fabric without twists and bends and which has a superior weight/strength ratio in comparison with conventional fabrics.

A ceiling, preferably made of wood, to be suspended from an existing ceiling of a room comprising a plurality of perimeter support members adapted to be attached to antipode walls of the room. The perimeter supports having a rabbit channel along their top edge. The suspended ceiling including a center beam having inner side and an outer side, the inner side designed to face the interior of the room, the outer side of the center beam having a pair of channels extending along the longitudinal dime...

A service associated with a call terminating at a subscriber can be triggered from a network node serving the subscriber when the subscriber is registered in the network and has a serving network node. In order to trigger the service also when the subscriber is not registered in the network, the network is provided with a service function which triggers the service for the subscriber when the subscriber is not registered in the network; and the call terminating at the subscriber is routed to thi...

A laminate obtained by laminating a resin composed chiefly of a polyester on a base material, said resin layer having a melt viscosity ratio (R) defined by the following formula (1), wherein .eta..sub.12.2 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 12.2 sec.sup.-1, and .eta..sub.1216 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 1216 sec.sup.-1, of not smaller than 2.0 at a melt extrusion temperature of the poly...

A portable stool has an enclosing wall assembly `A` and a flat seat `B` both made of the same or different plastics. The enclosing wall assembly is rectangular in plan view in its extended state and consists of a pair of right and left side walls (1a,1b) and a pair of front and rear transverse walls (2a,2b). Either the pair of side walls or the pair of transverse walls respectively consist of vertical halves hinged by mediate joints (4) to each other. Each side wall having a front and rear verti...

A resin impact absorber comprising a hollow columnar body having a honeycomb section or a hollow columnar body having a cylindrical shape, the hollow columnar body being made of a resin with a flexural modulus of 500 to 5000 kgf/cm.sup.2, wherein a reaction-compressibility curve at the time of compression in the lengthwise direction of the columnar body satisfies the following conditions: (a) yield strength.gtoreq.100 Tf/m.sup.2 and (b) compression energy absorption.gtoreq.50 Tf.m/m.sup.3. The r...

The present invention relates to a pipe joint made of resin used for laying pipes in which a high-purity liquid, ultra pure water or the like flow. According to the pipe joint of the present invention, a sealing surface pressure is generated in both axial and radial directions, providing thereby an excellent sealing property for a long period, and facilitate controlling a torque for fastening a pushing ring. The pipe joint made of resin according to the present invention comprises a joint body h...
