5 results about "Right triangle" patented technology

The invention discloses a pixel structure, a manufacturing method for the pixel structure, a display panel and a display apparatus. The pixel structure is provided with four kinds of sub pixels of different colors; each sub pixel is in a shape of right triangle; every two sub pixels of different colors form a rectangular virtual pixel; each virtual pixel is in array configuration; the sub pixels included in the adjacent two virtual pixels are different in colors; meanwhile, the right angles of every four sub pixels of different colors are focused into one point to form a rhombic physical pixel; and the rhombic shape of the physical pixel is also slanting rectangular. The physical pixels and the virtual pixels in the pixel structure are all rectangular, so that the pixel structure can perform both of common display and virtual display; no matter for realizing high-resolution virtual driving display adopting the virtual pixels, or for realizing low-resolution common display adopting the common (physical) pixels, images with relatively high uniformity can be always obtained, and a relatively good visual matching effect can be realized.

The invention discloses a method for quickly and safely overturning a large mold, and aims to provide an overturning method which is simple to operate and quick in overturning process. According to the technical scheme, the method comprises the steps that a mathematical model of a rectangular body surrounding a module is constructed with the help of CAE software, the gravity center position of a mold is found out, a calculated gravity center point A of the mold is vertically projected to the end face of one side in the length direction of the mold, and a projection point B is obtained; Respectively calculating two translation transfer starting points C and two translation starting points D on the end surface of one side of the mold at a quarter of the width size and a half of the height size of the mold; Lifting direction, Arbitrarily doing a point E, The corner angle of the right side edge of the mold serves as a supporting point of the mold contacting the ground when the mold is overturned clockwise, a right triangle is formed by perpendicularly connecting a point E with a ground plane of a gravity center projection point B of the mold, a point F is made at will in the same sidedirection of an overturning starting point E, and the height H1 of the right angle meets the requirement that the bottom edge is larger than or equal to 100 mm and smaller than or equal to 300 mm.

The invention discloses an excavator moving arm body locating component. A moving arm body lower supporting plate component accurate locating mode, an upper supporting plate component accurate locating mode, a moving arm body side face accurate locating mode, a moving arm body front end accurate locating mode and a moving arm body back end accurate locating mode are included. An upper supporting plate adjusting mechanism, an upper supporting plate locating component, a side locating component and a lower supporting plate locating component are supported and fastened in the middle of a moving arm body. A back end locating component is supported and pushed behind the moving arm body. A front end locating component is supported and fastened at the front end of the moving arm body. The right triangle principle is used for guaranteeing a welding mould with the excavator moving arm body associated hinged point distance error smaller than +/- 1.5mm. The welding mould is quick in location and reliable in welded product quality, the welding mould with the moving arm body welding blank piece associated hinged point distance error capable of being controlled in +/- 1.5mm can be widely used in the field of excavator moving arm body welding, and supporting locating is accurate and quick.

The invention relates to the technical field of building decoration, in particular to a ground fine leveling technology. The ground fine leveling technology comprises the following steps that horizontal lines with the same height are popped up on the four walls, close to the ground, of a room; a first drawing pin is pressed on the horizontal line of one wall, and a fine line is bound on the firstdrawing pin; cement mortar is laid in a right-angle triangular region at one corner of the room firstly; the cement mortar is embedded into a plurality of tile strips before the cement mortar is solidified, a smooth glaze surface of each tile strip faces upwards and is not stained, and the tile strips as much as possible are located on the same straight line; and before the cement mortar is solidified, one end of the fine line is pulled to move along the horizontal lines of the three walls without fixing the first drawing pin, meanwhile, the positions of the tile strips are manually adjusted so that the fine line can completely scratch the smooth glaze surfaces of all tile strips and then waiting for the solidification of the cement mortar. According to the ground fine leveling technology,the step of cake plastering is canceled, a replacement method which is simpler and easier to operate and high in efficiency is adopted, so that the construction time of ground fine leveling is greatly reduced.
