    Abstract: Disclosed is a double-bead horizontal and vertical spirit level having a transparent tube contains an air bubble, a basic liquid and bead insoluble in the basic liquid and having a density greater than that of the basic liquid. By comparing the relative positions of the air bubble and bead, the spirit level gives precise measurements. An apparatus using the spirit level and protractor can measure horizontal tilt angles of upper and lower surfaces, and vertical tilt angle of the vertical plane; it can also be further combined with a laser pen to measure the angle of elevation, distance, height of a remote object, tilt angles, draw a horizontal and plumb line. An apparatus where the long axis of spirit level is perpendicular to the axis of pivot, the long axis doesn't need to pass the axis of pivot and the space could be used to install a laser pen.

    Abstract translation: 公开了一种具有透明管的双珠水平和垂直水平仪，其包含气泡，基本液体和不溶于碱性液体的珠粒，并且具有比基本液体的密度更大的密度。 通过比较气泡和珠的相对位置，精确度给出精确的测量。 使用水平仪和量角器的设备可以测量上下表面的水平倾斜角度和垂直平面垂直倾斜角度; 还可以与激光笔进一步组合来测量远程物体的仰角，距离，高度，倾斜角度，绘制水平和垂直线。 其中长轴的水平面垂直于枢轴的装置，长轴不需要通过枢轴的轴线，并且该空间可用于安装激光笔。

    Abstract: A bearing 100 is provided between an outermost peripheral portion and an innermost peripheral portion of a flywheel 110. The bearing 100 includes a bearing rotor 120 firmly fixed to rotate integrally with the flywheel 110, and a bearing stator 130 provided inside the bearing rotor 120 in a fixed state, and includes a radially outer side magnet 121 and a radially inner side magnet 131 with the same magnetic pole on the bearing rotor 120 and the bearing stator 130 at positions facing each other. Accordingly, the bearing rotor 120 rotates at a position close to a rotating shaft 1, so that the rotation of the bearing rotor 120 and the flywheel 110 rotating with the bearing rotor 120 is stabilized, and the bearing 100 is compactly disposed at a position inside the outermost peripheral portion of the flywheel 110, thereby being capable of downsizing the device.

    Abstract: A ratchet wrench includes wrench body having a head which has a first side and a second side. A through hole is defined through the first and second sides. A first face and a second face are formed on the inner periphery of the through hole. The first face faces the first side. The second face faces the second side. A ratchet wheel is rotatably accommodated in the through hole and includes a first surface formed in a radial direction of the ratchet wheel, and the ratchet wheel further includes a second surface which extends in the axial direction of the ratchet wheel. The first surface contacts the second face. The second surface contacts the first face which is located substantially in an axial direction of the through hole. A sharp angle is formed between the first and second surfaces.

    Abstract: A method for manufacturing polyester filament spun-bonded non-woven fabric, comprising, i) drying respectively some polyester chips and black color masterbatch; ii) conveying the dried polyester chips and the dried black color masterbatch to a screw extruder for being melted and compressed into a viscous melt, and making the melt pass through a melt filter to remove impurities; iii) evenly distributing the filtered melt into each metering pump through a spinning manifold, cooling the output melt into filaments, drawing the filaments by airflow and the drawn filaments laying into fiber web, and preliminarily ironing and flattening the fiber web by a needle to obtain a fiber web-reinforced non-woven fabric; iv) winding the non-woven fabric by a winder and then shaping the non-woven fabric by a hot mill to obtain a polyester filament spun-bonded non-woven fabric. The polyester filament spun-bonded non-woven fabric exhibits superior tensile strength are excellent.
