62 results about "Stepping level" patented technology

In integrated circuits, the stepping level or revision level is a version number that refers to the introduction or revision of one or more photolithographic photomasks within the set of photomasks that is used to pattern an integrated circuit. The term originated from the name of the equipment ("steppers") that exposes the photoresist to light. Integrated circuits have two primary classes of mask sets: 1. base layers that are used to build the structures that make up the logic such as transistors, and 2: metal layers that connect the logic together.

Method for realizing individualized teaching through man-machine interaction

The invention relates to the technical field of artificial intelligence, discloses a method for realizing individualized teaching through man-machine interaction, and provides a method for realizing individualized teaching comprising automatic decomposition of learning tasks, automatic recommendation of test questions, positioning of error steps, explanation of questions and the other teaching links through the man-machine interaction. The method has the advantages that in addition to data preparation and parameter setting in the first step, the participation of any human teachers is all not needed in other steps, thereby reducing the occupation of human resources, in particular to educational resources to the maximum extent, compared with a traditional explanation mode taking 15-20 minutes on average, by determining wrong reasons and performing step-level precise explanation, not only can content that does need to be explained be skipped to the maximum extent for specific learning conditions of a user, the questions of the user are explained emphatically, the roots of the questions are excavated deeply, so that the user can understand knowledge points more easily, but also the explanation time is shortened to 2-3 minutes, thereby greatly improving the learning efficiency of the user.

Electrically driven axle of a dual track vehicle

The invention relates to an electrically driven axle of a dual track vehicle having drive shafts allocated to the wheels and an axle support having a plurality of wheel-guiding drivers fastened thereto, wherein at least one electrical motor or an axle drive is fastened to the axle support and furthermore a housing comprising elements for providing electrical energy for the electrical motor or for an electrical drive motor connected to the drive shafts via the axle drive is fastened to the axle support or forms a component of the axle support in the form of a main body. The housing is designed in a stepped manner in the side view and consists of an upper shell and a lower shell, the coupling joint of which extends upwardly toward the rear of the vehicle. According to the invention there are also front and rear continuous cross-members, having bearings for linking the axle to the vehicle body in the two end regions thereof. Wheel-guiding drivers are fastened via bearing brackets on the housing and/or on one of the cross-members and/or on a molded part flanged laterally to the housing. Furthermore, according to the invention, a fuel tank installed in the vehicle for supplying an optionally provided internal combustion engine can encompass the step level which is front-most in the driving direction formed by the housing.

Ore-dressing process for extracting copper and silver

The invention provides an ore-dressing process for extracting copper and silver. The ore-dressing process comprises the following steps: (A) grinding raw ores, and grading the ground ores to obtain ore pulp; (B) carrying out rough concentration on the obtained ore pulp in the step (A) to obtain first rough concentrate and first coarse slag; (C) carrying out concentration on the obtained first rough concentrate to obtain concentrate and first middlings; scavenging first coarse slag to obtain second middlings and second coarse slag; (D) scavenging the second coarse slag to obtain third middlings and tailings; and (E) carrying out rough concentration on the first middlings, gradually returning the second middlings and third middllings to the previous step level by level, and finally obtaining concentrate and tailings. The process is used for extracting copper and silver from raw ore with high argillization rate and high oxidation rate, ore grinding is firstly carried out in the process for extracting the copper and silver, the ore grinding granularity, rough concentration and floatation agent are strictly controlled by virtue of a floatation process of rough concentration, scavenging and concentration, so that the recovery rate of copper and silver is relatively high. The experiment result shows that the recovery rate of the copper and silver can reach more than 90 percent.
