Abstract: A method for improving fixing effect of a ceramic strip heater is performed as follows. An electrode material is applied to each end of an upper surface of an alumina ceramic substrate by printing, followed by drying and sintering to form an electrode. A heating paste is applied to the upper surface of the alumina ceramic substrate by printing to connect two electrodes on both ends of the alumina ceramic substrate, followed by drying and sintering to form a heating filament. A glass paste is applied to a lower surface of the alumina ceramic substrate by printing, followed by drying and sintering to form a first glass layer. Another glass paste is applied onto the heating paste by printing, followed by drying and sintering to form a second glass layer, so as to arrive at the ceramic strip heater.

Abstract: A display support having a freely adjustable height, including a base and a connector for installing a display, wherein an upper connecting arm and a lower connecting arm, which are parallel to each other, are arranged between the base and the connector. The display support further includes a mechanical spring, wherein an end of the mechanical spring is hinged with the connector or the lower connecting arm, the other end of the mechanical spring is hinged with a threaded sliding block, the threaded sliding block sleeves on a threaded rod, the threaded rod is arranged in the base, so that when an end part of the threaded rod is operated to drive the threaded rod to rotate, the threaded sliding block moves along the threaded rod, and a position of the threaded sliding block on the threaded rod is adjusted according to the weight of the display on the connector, so that when the connector is moved upwards or downwards, the connector is stopped at different heights relative to the base.

Abstract: A load-energy efficiency evaluation and monitoring method includes an actual part processing number and a theoretical part processing number of the numerical control machine tool within an evaluation period are obtained to calculate a loading performance of the numerical control machine tool. A waste time value and a standby power value of the numerical control machine tool are obtained to calculate a waste energy value of the numerical control machine tool. A single-part actual processing energy consumption is obtained and used, together with a single-part ideal processing energy consumption, to calculate the load-energy efficiency of the numerical control machine tool. A relationship model between the load-energy efficiency and the loading performance of the numerical control machine tool is built based on the obtained model of the load-energy efficiency of the numerical control machine tool and the obtained model of the loading performance of the numerical control machine tool.
