Abstract: A chip with a current-mirror-like voltage source is shown. The current-mirror-like voltage source has a first n-channel Metal-Oxide-Semiconductor Field-Effect Transistor (NMOS), a second NMOS, and an operational amplifier. The first and second NMOSs have drains coupled to a first voltage source Vdd1. The operational amplifier has an output terminal coupled to the gates of the first NMOS and the second NMOS, a negative input terminal coupled to the source of the first NMOS to form a negative feedback loop, and a positive input terminal coupled to the source of the second NMOS to form a positive feedback loop. The operational amplifier is powered by a second voltage source that is greater than the first voltage source, to operate the first and second NMOSs in their saturation region, and thereby the current-mirror-like voltage source outputs a load current mirrored from a first current.

Abstract: The present application relates to metal cutting, and more particularly to a cutting fluid and a preparation method and an application thereof, especially the application in the processing of niobium-tungsten alloy (NB521). The preparation method of the cutting fluid is simple and requires low production cost. In the mechanical processing of niobium-tungsten alloy (NB521), the cutting fluid has good cooling performance, lubricity, load-bearing capacity, friction reduction and vibration absorption, and long service life. It also can effectively avoid built-up edges, thereby improving the service life of cutting tools and the processibility of materials. Therefore, products of good quality are produced to improve the yield, especially in the deep hole machining, and thus the cutting fluid of the present application is suitable for a wide range of applications.

Abstract: A stored procedure call may be transmitted to a database to execute a database query. As a result of the stored procedure call, results including a result record satisfying the database query and a set of records related to the result record may be received. The results may be stored in a local cache.
