An inflatable cushion bag for striking includes an outer wall and an inner wall that is positioned inside and longitudinally with the outer wall looped around the inner wall. A first radial wall is joined to each of and connects between the outer wall and the inner wall at a first end and is sealed so that free airflow is blocked at the first end. A second radial wall is joined to each of and connects between the outer wall and the inner wall at a second end and is sealed so that free airflow is blocked at the second end. At least one intermediate radial wall is placed longitudinally between the first radial wall and the second radial wall and transversely between the outer wall and the inner wall. The intermediate radial wall may have a small opening such as a hole with a diameter less than ½ inches or an equivalent so that the opening allows a slow airflow through the intermediate radial wall for inflating or deflating the bag and, when inflated, restricts airflow through the opening to give a shock absorber effect to make the outer wall an added cushion when punched or kicked.

A dense phase swirl pulverized coal burner comprises a primary air channel, a direct flow secondary air channel and a outermost swirl secondary air channel; and multiple levels of pulverized coal concentration rings are arranged axially at intervals along the oil gun casing in a straight tube section of the primary air channel, so that pulverized coal air flow is distributed thickly outside and thinly inside the primary air nozzle. In the invention, dense phase pulverized coal outside the primary air nozzle passes through guide vanes, forms disturbed flow, is ejected into a furnace and mixes with high temperature backflow flue gas rapidly and sufficiently at an outlet. Meanwhile, dilute pulverized coal air flow at the center is ejected into the furnace by direct flow, ensuring subsequent mixing and combustion of pulverized coal flow. The primary air nozzle and the secondary air nozzle are provided with cone flaring structures with certain angle to effectively control appropriate mixing of secondary air and pulverized coal. The invention has advantages of strong ignition and combustion stability, good coal adaptability, low nitric oxide emission, simple primary air channel structure and small resistance, which effectively slows wear rate of parts.

The present invention relates to a method of manufacturing an FRP tubular body. The manufacturing method includes the steps of winding a fiber reinforced resin member containing a fiber and a matrix resin around a mandrel, thereby obtaining an intermediate formed body, winding a wrapping tape around an outer peripheral surface of the intermediate formed body (6) with an application of a tension, curing the matrix resin in the intermediate formed body having the wrapping tape wound therearound, and pulling the mandrel out and removing the wrapping tape after the curing step, thereby obtaining a cured tubular body. It is preferable that a fabric tape should be used as the wrapping tape. It is preferable that a tensile stress to be applied to the fabric tape (8) should be set to be equal to or higher than 5 (Mpa) and is equal to or smaller than 150 (Mpa) at the tape winding step. In the manufacturing method, the matrix resin can be effectively extracted at a subsequent step to the winding step.

An object resembling the cover of a hardbound book comprises two panels connected by a spine. The outside hinge configuration of the invention prevents the spine from collapsing, even if there are no contents between the two panels. The invention lends itself to a wide variety of book-like products (e.g., a book-like holder for a compact disc and accompanying booklet) where the contents are of changing width (thickness) or where the spine must be of a specific width, irrespective of the width of the contents, and further allows for a binding for a book to be fabricated prior to assembly or insertion of its pages. A hinged cover consistent with the invention comprises a spine and two rigid panels, each panel coupled to the spine and disposed rotatably with respect to the spine, and the spine serves as a hinge stop for each rigid panel, such that each panel, when rotated toward the other panel, is constrained from rotating substantially beyond 90 degrees with respect to the spine. A method of constructing a cover consistent with the invention comprises disposing a rigid front, rear, and spine panel core onto a sheet of pliable material, such that the width of the space between the spine panel core and the other panel cores is based on at least the sum of the thickness of the spine panel core and twice the thickness of the sheet of pliable material.

Methods and apparatus for manipulating digital images. A warping module is described that enables the manipulation of a surface by selectively deforming portions of the surface while maintaining local rigidity. The user may position multiple control points on a surface to constrain deformation. The user may specify multiple properties (e.g., translation, rotation, depth, and scale) at each control point. A mesh may be overlaid on the surface. The warping module may perform an initialization in which the properties are propagated other vertices in the mesh to generate an initial deformed mesh. The warping module may then perform an iterative optimization operation on the deformed mesh to improve the deformation while retaining local rigidity. Thus, instead of moving every pixel in the surface, the warping module moves or adjusts coordinates of the vertices of the mesh. The surface is then deformed according to the deformed mesh.

A vehicle (1) includes first and second rear-floor cross members (4, 5) provided between right and left rear-floor side members (2, 2) in a vehicle body rear part and a pair of right and left rear-floor cross member braces (6, 6) provided therebetween. The second rear-floor cross member is formed by a three-member connected body consisting of right and left extension parts (52, 52) connected to the right and left rear-floor side members and a body part (51) arranged therebetween. The rear-floor cross member braces are connected to the body part (51) of the second rear-floor cross member. Shock energy of a shock load applied to the vehicle body rear part from the rear can be absorbed efficiently while the deformation of a rectangular region surrounded by the first and second rear-floor cross members and the right and left rear-floor cross member braces is restrained.
