Abstract: A non-destructive testing method for flexural strength of fine ceramic, an apparatus, and a storage medium, including adjusting an uncut intact fine ceramic test sample to an ultrasonic testing position, and fixing the test sample; adjusting an ultrasonic testing instrument, controlling and adjusting the positions of ultrasonic testing probes of the ultrasonic testing instrument until the ultrasonic testing probes, the fine ceramic test sample and the resiling direction are located on the same plane, performing ultrasonic testing on the test sample, and collecting ultrasonic testing data of the test sample; adjusting the position of the fine ceramic test sample until a resilience testing rod and the test sample are located on the same plane and fixed, performing resilience testing on the test sample, and collecting resilience testing data of the test sample; and building a data model, or substituting testing data into the pre-built data model.

Abstract: A back drilling processing method for a circuit board includes: obtaining a board to be back drilled, wherein the board includes a target signal layer and at least two conductive reference layers; drilling a through hole at a set position of the board, and obtaining an actually measured spacing between two conductive reference layers; in response to a hole to be back drilled being of a first type, determining a target back drilling depth; controlling a drilling bit to drill for the target back drilling depth towards the target signal layer; in response to the hole to be back drilled being of a second type, determining a target relative height of a back drilling end point relative to a machine; and controlling the drilling bit to drill for the target relative height towards the target signal layer. The back drilling does not drill through the target signal layer.

Abstract: A gripping arm for a clamping attachment for a forklift has a load engaging inner arm including portions defining a load face. The inner arm is pivotal about a first axis parallel to the load face and pivots about a second axis normal to the first axis to engage and secure a load.

Abstract: A process for adsorptive desulfurization of gasoline or diesel oil or aromatics lower than C12 containing organic sulfide impurities, wherein these feedstocks contact an amorphous alloy adsorbent comprising nickel as a major active component in a fluidized bed reactor or a magnetic-stabilized fluidized bed reactor or a slurry bed reactor. There is only a single diffuse peak at 2?=45° in the 2? range from 20° to 80° in the X-ray diffraction (XRD) pattern of the adsorbent. The adsorbent consists of 50-95 wt % of nickel, 1-30 wt % of aluminum, 0-35 wt % of iron, and 0-10 wt % of one or more metals selected from copper, zinc, molybdenum, chromium, and cobalt.
