Abstract: The present disclosure relates to an accelerator lead-out window and a preparation method thereof, wherein an overall structure of the accelerator lead-out window is integrally formed by adopting an additive manufacturing method; a window film is made of titanium alloy, and each component ratio is calculated by a weight percentage, wherein Al:4.5-7.5%, Mo:4.1-6.9%, V:4.1-6.9%, Nb:3.1-4.5%, Cr 1.5-3.5%, Ta:0.5-1.5%, and the remaining amount is titanium and other unavoidable elements. A window frame is made of aluminum alloy, and each component ratio is calculated by a weight percentage, wherein Zn:5.1-6.9%, Mg:2.1-3.9%, Cu:1.2-3.9%, Cr:0.18-0.28%, Fe?0.30%, Si?0.15%, Ti?0.15%, Mn?0.10%, and the remaining amount is Al and other unavoidable elements.

Abstract: A conductive path, such as a copper patch, between decoupling capacitors and a high frequency integrated circuit, may be oxidized to improve the power delivery performance. Specifically, adding the resistance in the conductive path by oxidizing the conductive path increases the dampening of the peak impedance at a given peak frequency. In some embodiments, a mask may be used to control the amount of the conductive path that is oxidized.

Abstract: A composition of matter, comprising a cannabinol compound having the structure ##STR1## wherein, Q is --C(R.sup.1) (Y.sup.1)--(CH.sub.2).sub.n ----Z.sup.1 ; R.sup.1 is --H or --CH.sub.3 ; Y.sup.1 is --CH.sub.3 or Y.sup.2 ; Y.sup.2 is --N.sub.3 or --NCS; n is 4 or 6; Z.sup.1 is --H, when Y.sup.1 is Y.sup.2, or is Z.sup.2, when Y.sup.1 is --CH.sub.3 ; and Z.sup.2 is --N.sub.3 or --NCS.This composition has good binding affinity to the cannabinoid receptor and therefore, is useful as a receptor probe.
