The invention solves a technical problem of low reliability of the conventional cashbox lock and provides a cashbox safety lock mechanism with low lock body destructive power and high precision. The cashbox safety lock mechanism is arranged between the box body of the cashbox and a sliding door, and comprises a lock arm clamping member and a movable lock arm component which are arranged on the box body of the cashbox and the sliding door respectively, wherein the movable lock arm component comprises a lock arm connected with the sliding door movably through a rotating column and a driving part driving the lock arm to rotate; two picks extend out of the first outer end of the lock arm, and a clamping groove matched with the lock arm clamping member is arranged at the second end of the lock arm; the driving part comprises a movable lock cylinder arranged on the sliding door and a driving part fixedly connected with the rotating end of the lock cylinder; and the driving part is arranged between the two picks. The lock body and locking part of the lock mechanism are separated so that the lock body does not withstand any force; and thus, the service life and safe performance of the lock are improved.

A process flow device that includes a self-averaging orifice plate type of primary flow element with a high pressure tap located on or incorporated into its upstream surface, and a low pressure tap located on or incorporated into its downstream surface, for measuring, by a differential pressure process, the volumetric rate of fluid flow at a point in a fluid carrying conduit where the velocity profile of the fluid is asymmetric with respect to the longitudinal axis of the conduit. The improved pressure tap configuration consists of two fluid conduits, one carried by each of the downstream and upstream faces of the orifice plate, establishing fluid communication between openings in the downstream and upstream faces of the orifice plate and their respective terminal pressure ports. Location of the pressure taps on the faces of the orifice plate in this manner allows for increased resolution of the pressure signals by minimizing the effects of upstream pipe flow disturbances on pressure taps used in conjunction with conditioning orifice plate primary flow elements, especially those with higher beta ratios.

A radar device includes a generation unit, a transmission unit, and a control unit. The generation unit selectively generates a set of a plurality of transmission signals whose center frequencies are different from one another within an assigned frequency band. The transmission unit emits the transmission signals. The control unit controls the generation unit so as to vary the center frequencies for each emission of the transmission signals.

A reagent matrix composition disposed on an electrically conductive electrode to form an in-vivo sensor for a predefined analyte includes a first hydrogel layer containing an enzyme that is a substrate for the analyte adjacent the electrically conductive electrode and a composite membrane layer disposed onto the first hydrogel layer where the composite layer includes a membrane hydrogel containing a plurality of microspheres. The plurality of microspheres is made of a material having no or little permeability to the analyte and a substantially high permeability to oxygen.

The device has the beneficial effects that the oxygen consumption rate in any time period in the oxygen deficit process can be collected, and the harm of limit oxygen consumption to animals is avoided; and the experimental precision is high.

The present application relates to the measurement technology of the homogeneity in optical materials, and more particularly to a method for evaluating and controlling temperature influence on a homogeneity test for infrared optical materials. The precision of the test results is found to be affected by local small temperature changes of the sample during the homogeneity test for the refractive indexes of infrared optical materials, the invention establishes a two-dimensional numerical table in which the test precision requirements of a refractive index homogeneity test for infrared optical materials correspond to the ambient control temperatures in the test room corresponding to the influence of temperature changes on the refractive index of different infrared optical materials. In addition, related calculation formulas are established for theory analysis, numerical calculation and form-designing. The method of the present invention accurately guides the temperature control for the precision of the homogeneity test for infrared optical materials.

The invention provides a processing method for metal pipe fittings, which relates to the technical field of mechanical manufacturing and processing. During operation, metal pipe fittings need to be cut, pipe notched, positioned and clamped, welded, welded seam processed, sealed and put into storage, etc. steps of processing. The invention can solve the problems existing in the angle butt welding process of the existing metal pipe fittings. When the existing pipe fittings are connected by welding, it is necessary to manually control the angle adjustment of the pipe fittings according to the angle of the welded pipe fittings. During the operation, it is necessary to manually control the clamps to fix the pipe fittings. The accuracy of manual adjustment of the welding angle of pipe fittings is poor, which affects the precision of the connection angle of pipe fittings. Manual adjustment of pipe fitting angle welding operations requires manual adjustments for pipe fittings with different welding angles. The accuracy of angle adjustment is low, which affects work efficiency and pipe fitting welding the quality of.

The invention discloses a lens module and a projection device. The lens module comprises a lens cone, a supporting part and a buffering part, wherein the supporting part is arranged on the lens cone in a sleeving mode and supports the lens cone, the buffering part is arranged between the lens cone and the supporting part, and the buffering part is provided with a main portion and multiple buffering portions. Each buffering portion is provided with a boss and a connecting portion, wherein the boss abuts against the lens cone, the connecting portion is connected with the main portion and the boss, and the connecting portion can deform. Hollow areas are form in the buffering part and correspond to the bosses, a gap is formed between the buffering part and the lens cone, and the gap and the hollow areas are used for providing a space for deformation of the buffering portions so that external impact can be buffered effectively, the situation that poor images are generated due to deviation of the light path of a lens can be avoided, and imaging quality can be guaranteed. Meanwhile, the buffering part abuts against the lens cone and deforms to counteract assembly tolerance, and the situation that the precision of the light path is affected due to deviation of the light path when local stress is too large is avoided.
