Patent JP-H0455295-A (JP)
Title: Wheel crane
Inventor: MIYAZAWA HIROSHI
IPC: B66C23/42
Filed: 1990-06-25
Abstract: PURPOSE:To prevent to make a disturbance of the field of vision by a boom derricking cylinder in the running condition, by providing the second link to guide the connection between the first link and the boom derricking cylinder in the direction to extend a refraction link body which is composed of the boom derricking cylinder and the first link, following the erection of the boom. CONSTITUTION:The front end of the first link 10 is connected to the rear end of a boom derricking cylinder 9, and the rear end of the first link 10 is connected to a boom 5. When a refraction link body A composed of the boom derricking cylinder 9 and the first link 10 is expanded following the erection of the boom 5, the stroke of the boom derricking cylinder 9 is increased. As a result, the largest erection angle of the boom 5 is secured even though the boom derricking cylinder 9 is a short device arranged at the lower side of the boom 5. Since the cylinder 9 can be arranged in the condition not crossing the side of an eye point P, in the lower side of the boom 5 (within the boom width), the boom width and the cabin width receive no restriction from the boom derricking cylinder, and thereby the boom strength and the residental freedom can be secured, and the field of vision in the running condition is also improved.

Title: Method for correcting distortion of image of slanting projection
Inventor: NAGASAWA MASANAO
IPC: G02B27/00
Filed: 1989-06-29
Abstract: PURPOSE:To project an image in a similar shape without being affected by a projection angle by arranging a plane body to be projected slantingly in parallel to an image formation plane and also installing an image forming lens in parallel to the image formation plane. CONSTITUTION:The body 3 to be projected and the image forming lens 4 are set parallel to the image formation plane 5 at all times. Consequently, even when the image formation plane is not perpendicular to an optical axis, an image similar to the plane body to be projected can be projected. For example, when an image is projected slantingly upward upon a screen at a position higher than the eye from this side, the similar image can be projected while the screen is held vertically.

Title: Manufacture of fiber reinforced cement plate
Inventor: MATSUKAWA ATSUSHI
IPC: C04B28/18
Filed: 1991-06-11
Abstract: PURPOSE:To prevent the generation of pills because of pulp fiber by mixing silica fume with pulp fiber, making the silica adhered evenly on the pulp fiber surface, and then mixing the same with a blended material such as aggregate and feeding the same into a dry belt molding device. CONSTITUTION:When a blended material is dry mixed, first silica fume and pulp fibers are mixed together, and silica fume is made to adhere to the pulp fiber surface and then mixed with another blended material such as aggregate and fed into a dry belt molding device. Then, cement blends B1-B3 are fed laminarily onto a molding belt A, and water is added therein, and the blends are compressed by rolls R and belt-shaped plates G are continuously molded. As the number of curds generated in the material to be fed is reduced almost by half, the reinforcing efficiency of reinforcing fibers is increased correspondingly to the reduction, and cement plates having the strength equivalent to asbestos can be molded.

Title: Combustion chamber for antechamber type engine
Inventor: IMOTO KOUJI
IPC: F02B19/14
Filed: 1982-09-28
Abstract: PURPOSE:To prevent the occurence of an incomplete combustion that happens when a reduction in NOx is aimed at in delaying the fuel injection timing, by tilting a part around at least the opening part of a antechamber nozzle hole of the end face at the antechamber of a partition wall. CONSTITUTION:An antechamber nozzle hole 2 pierces a partition wall between an antechamber 1 and a main chamber 3, and the antechamber 1 is of semispheric type in structure at its upper part, while a bottom surface 1a of the end face at the antechamber side of the partition wall thickens the outward side of the partition wall and tilts it in addition. When the minimum angle between an axis center line of the antechamber nozzle hole 2 and the antechamber bottom surface 1a is set down to theta2, while another minimum angle between the axis center line of the antechamber nozzle hole 2 and the main chamber side end face is set down to theta1, the angle is formed into theta2<theta1 like that. With a tilt of the antechamber bottom surface 1a, fuel injection timing is delayed to some extent from the standpoint of reducing NOx whereby even if a piston 7 ignites inside the antechamber 1 during its descendent stroke, gas flowing from the antechamber 1 to the main chamber 3 is checked so that combustion inside the antechamber 1 is accelerated and stabilized in consequence. Afterward, with a pressure rise inside the antechamber 1, gas flows into the main chamber 3 and in addition, injection velocity is speedy so that the formation of a fuel-air mixture inside the main chamber 3 and the combustion both are accelerated.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an error in advance by equalizing the number of projecting polygons with the number of triangles obtained by a triangle dividing method at the worst and to mostly make it less than the number of the triangles. SOLUTION: Whether each vertex of a recessed polygon is recessed or projected is judged, all the recessed vertexes are stored (SP 1) in a recessed vertex list and whether a recessed vertex exists in the recessed vertex list is judged (SP 2). When the recessed vertex exists, the recessed vertex is fetched (SP 3) from the head of the recessed vertex list, three vertexes consecutive in a prescribed direction including the fetched recessed vertex are noticed (SP 4) and whether a triangle formed by these three vertexes can be cut off or not is judged (SP 5). Then when it is judged that the triangle can be cut off, whether an N-polygon can be cut off not is judged. (SP 6). When it is possible, the N-polygon is cut off (SP 7) but when it is impossible on the contrary, the triangle is cut off (SP 8).

Abstract: PURPOSE:To spontaneously generate a turning flow and prevent turbulance by forming in an axially symmetric enlarged or contracted flow passage an axial flow which has a circular flow speed smallest portion concentric to the flow passage. CONSTITUTION:An axial flow 101 is formed in a reducer 2, wherein high speed flow is distributed to a portion near a tube wall. Speed distribution at a sectional area of the flow is going to be a parabolic shape as it proceeds, so that it is turned to be a flow 102 having a circular flow speed smallest part 103. A turning flow 104 is spontaneously generated with the flow speed smallest part being a zero point of a turning flow speed, succeeding in a direct tube portion 3 as a turning flow 106. Turbulance is thus prevented by the spontaneous turning flow. In order to realize this in a practical device, fluid is flowed oppositly to the flowing direction for conversing the direction, and a semi-spherical shell is adopted so as to easily form the high speed flow along the tube wall. The practical device is composed of a semi-spherical shell l, the reducer 2 continuously connecting thereto, and the pipe passage 3 connecting thereto. A fluid charging port 5 is provided thereon, and its section is a circular shape or a shape which is prepared by crushing transversely a circle.
