A chemically and spectrally-sensitized emulsion has been described, wherein said emulsion comprising (100) cubic silver halide grains with an average edge length of from 0.2 up to 1.5 mum, has been spectrally sensitized by addition at least three trimethine dyes: a main spectral sensitizer added in an amount of at least 85 mole % of all spectral sensitizers added, followed by adding a second spectral sensitizer in an amount of not more than 10 mole % and a third spectral sensitizer in an amount of at most 1 mole % wherein at least said main spectral sensitizer has two benzoxazole rings in its chemical structure, at least said third spectral sensitizer has two benzimidazole rings in its chemical structure and wherein the said second spectral sensitizer has a structure more sterically hindered than the structure of the other spectral sensitizers. A light-sensitive silver halide photographic film material coated with such emulsion and a radiographic screen / film combination has been described.

The present invention discloses a preparation method for FD mature kiwi fruit in-situ slices. The method comprises the following steps of selecting fruits and cutting the fruits into slices with a thickness of 0.5-1 cm, quick-freezing the kiwi fruit slices with a freeze dryer at a refrigeration rate that a freezing process from room temperature of about +25 DEG C to -20 to -30 DEG C is completed within 2-3 hours; remaining the quick frozen kiwi fruit slices for 30 minutes to 2 hours, and carrying out sublimation for drying. The preparation method for the FD mature kiwi fruit in-situ slices adopts quick-freezing so as to maintain the original shape and original flavor of the kiwi fruit slices; and vacuum keeping and heating for sublimation are simultaneously conducted so as to remain the original structure of pectin in the kiwi fruits, prevent saccharification and make the water content of the dry kiwi fruit slices meet the requirement. In addition, the freeze drying method maintains the original color of the kiwi fruit slices, concentrates the nutrients in kiwi fruits and significantly reduces costs compared with a conventional freeze-drying method.

A vehicle window lifting motor capable of overload protection relates to the technical field of motors. The motor includes a connector. An inner wall of the connector is provided with uniformly distributed clamping grooves, an output shaft is connected on a middle part of the connector in a clamped manner, and evenly distributed fixed columns are fixedly connected on an inner wall of the output shaft. In the vehicle window lifting motor capable of overload protection, clamping blocks and the clamping grooves are used in a cooperative manner, the clamping blocks are connected with the clampinggrooves in a clamped manner in an initial state, and the connector is enabled to be connected with the output shaft in a clamped manner; when the rotating output shaft suddenly stops, a limiting blockmoves towards a front side due to centrifugal force, an electrically conductive sheet is driven to move toward the front side, the electrically conductive sheet is separated from a rheostat, a circuit for suspending liquid is disconnected, the suspending liquid is turned into fluid, the clamping blocks are squeezed into the output shaft under the action of the clamping grooves, piston blocks moveto both sides under the action of the suspending liquid to make the output shaft idle, thus overload protection can be achieved, overload use of the motor can be prevented, and service life of the motor is prolonged.

The invention discloses a probe for a quick tester of hydrogen content in an aluminium alloy fusant and a manufacturing method thereof. In the hydrogen measuring device used at present, a hydrogen gauge probe has the problems of long measuring period and high price. The manufacturing method of the invention comprises: a, according to parts by weight, 16 parts of silicon carbide with 150 meshes, 5parts of bentonite, 2 parts of powdery alumina, 1 part of powdery copper oxide and 4 parts of gypsum powder are put into the same crucible to be evenly and fully stirred, 7 parts of water are added, and the mixture is evenly stirred to form a probe raw material; b, the weighed probe raw material is loaded into a die to be compacted and shaped; c, the probe is taken out and is dried at room temperature, and then the probe head is completely dipped into phosphoric acid for 3-4 minutes; and d, after being totally dried, the probe dipped in acid is baked at high temperature. The probe of the invention is a mating device for quickly measuring the hydrogen content in the aluminium alloy fusant.
