Systems, apparatus, and methods for monitoring temperature at a region near a surgical site during a procedure. A temperature-indicating element of an electrosurgical device comprises an indicator composition adapted to undergo a change in appearance in response to a pre-defined temperature range. The change in appearance of the temperature-indicating element indicates to the operator of the device a temperature condition at the working end of the device.

A valve timing change apparatus of the present invention is an apparatus for changing the relative angular position between a cam shaft 10 and a sprocket 30, which comprises an angle change mechanism 80 changing and holding the relative angular position between the cam shaft 10 and the sprocket 30 by oil pressure, an oil pressure generating mechanism 90 for generating oil pressure for driving the angle change mechanism 80 by relative rotation, and an electromagnetic retarder 100 for generating relative rotation at the oil pressure generating mechanism 90. With this structure, simplification and downsizing of the apparatus, reduction of engine load, suppression of oil pressure drop, etc. can be obtained. Then, a plurality of the apparatus can be mounted on an engine. In this manner, downsizing of the valve timing change apparatus, reduction of engine load, downsizing of an oil pump, etc. can be obtained.

A stencil is made by thermally forming perforations arranged in both a main scanning direction and a sub-scanning direction in a thermoplastic resin film of heat-sensitive stencil material by the use of a heat source which is heated through supply of energy. Supply of energy to the heat source is cut so that the quotient obtained by dividing a maximum diameter of a perforation at the time at which supply of energy to the heat source is cut by the energizing time is not smaller than 0.015 m / s and not larger than 0.23 m / s.

The invention discloses a parallel type multi-effect vacuum membrane distillation apparatus and method and belongs to the field of membrane distillation. The parallel type multi-effect vacuum membrane distillation apparatus which is low in energy consumption comprises n-stage parallel membrane distillation units; tube passes of a first feed liquid tank, a booster pump, a hollow fiber membrane module form a first closed circulation loop; tube passes of the hollow fiber membrane modules of the second stage to the nth stage, the shell pass of a shell-and-tube heat exchanger of the former stage, the feed liquid tank and the booster pump of the corresponding stage form a second closed circulation loop, a third closed circulation loop..., an nth closed circulation loop. The tube pass of a shell-and-tube heat exchanger of the nth stage is communicated with a cooler. In each stage, the outlet of the shell pass of the hollow fiber membrane module and a finished product collection tank are communicated with the inlet of the tube pass of the corresponding shell-and-tube heat exchanger; a thermometer is arranged on a connection pipeline between the booster pump and the hollow fiber membrane module. Besides, the outlet of the tube pass of the shell-and-tube heat exchanger of the first stage to the outlet of the tube pass of the (n-1)th stage are respectively communicated with the outlet of the shell pass of the hollow fiber membrane module of the next stage and then communicated with the inlet of the tube pass of the shell-and-tube heat exchanger of the next stage, and the outlet of the tube pass of the nth shell-and-tube heat exchanger is communicated with a vacuum pump.

A composite catalytic material, a preparation method and an application in the preparation of 2,5-dimethylfuran mediated by in-situ dehydrogenation and hydrogenation coupling reactions. The catalytic material is composed of active bimetallic and magnetic inorganic-organic hybrid polymer supports with Lewis acidic sites and Brϕnsted acidic sites, and has strong 1,4‑butanediol dehydrogenation ability and 5‑hydroxymethyl Furfural-based hydrogenation ability; the adopted segmental temperature control method can selectively control the catalytic performance and synergistic effect of active bimetallic and magnetic inorganic-organic hybrid polymer carriers, effectively avoid the formation of by-products, and increase the yield of target products , has a good potential for industrial application.

The present invention provides a method for connecting silicon carbide ceramic materials. The method comprises: processing a concave threaded hole at the to-be-connected position of one silicon carbide ceramic material; and processing the to-be-connected position of the other silicon carbide ceramic material into a projecting bolt shape with threads, and depositing a middle connection layer on the threaded surface, wherein the deposited threads and the threaded hole form threaded combination, the middle connection layer is a laminated structure and comprises at least two titanium layers, and a carbon layer is arranged between the adjacent titanium layers. According to the present invention, the silicon carbide ceramic materials to be connected are integrally connected through the mechanical matching between the threaded holes and the bolt; and the connection interface produces the chemical diffusion effect through the external heat source heating so as to further enhance the connection of the silicon carbide ceramic materials to be connected.

The invention discloses an engineering machinery braking pedal which comprises a foot pedal (2). The foot pedal (2) is connected with a rotation rod (4) in a hinged mode. The rotation rod (4) is connected with a rotation plate (7) in a hinged mode. A pedal switch (5) is arranged on the foot pedal (2). The pedal switch (5) is connected with an electromagnetic valve on a power system oil way through a circuit. The invention further discloses an operating method of the braking pedal. According to the technical scheme, power cutting-off is added before a braking process, energy supplied to an engine is reduced by cutting-off the oil way, and therefore traction force of a whole vehicle is reduced. Then, braking is carried out through an air brake valve, therefore, the air brake valve works with low loads, and reliability and safety of braking are improved.
