A liquid cooling system, enabling protection from corrosion due to liquid coolant for a long time-period (5–10 years) while cooling a heat-generation body effectively, comprises a pump 108, a heat-receiving jacket 107, a radiator for radiating heat into an outside, being made up with a heat-radiation pipe 201 and a heat-radiation plate 202, and further a tank 203 for accumulating the liquid coolant 209 within an inside thereof, wherein those are connected in a closed-loop, so as to circulating the cooling liquid therein, thereby cooling the heat-generation of a CPU 106, being a heat-generation element, effectively, through the heat-receiving jacket 107, and further a water-permeable bag 204 is disposed in a portion of flow path of the cooling liquid, which receives microcapsules 10 therein, each enclosing in an inside thereof anti-corrosion agent 20 for suppressing the corrosion due to the cooling liquid, including such as, a water, etc.

A thread-forming screw (11; 21; 31; 51), has a stem (12) with at least one thread (14; 24; 34; 54) arranged, at least regionwise, over its circumference, and a plurality of cutting elements (16; 26; 36; 56) arranged in a respective plurality of recesses (15; 25; 35; 55) formed in the at least one thread (14; 24; 34; 54), with the cutting elements (16; 26; 36; 56) having a hardness greater than a hardness of the at least one thread (14; 24; 34; 54) and formed as weld beads received in the recesses (15; 25; 35; 55).

The present invention relates to one kind of surface anticorrosive antiscaling and heat conducting coating for evaporating condenser, and the surface anticorrosive antiscaling and heat conducting coating consists of base material in 100 weight portions, water in 120-140 weight portions and anionic surfactant in 0.3-0.5 weight portions. The base material is modified water glass containing phosphate, sulfonated vinyl chloride polymer and melting liquid in the weight ratio of 10-15 to 15-25 to 2-5. The coating has excellent anticorrosive, antiscaling and heat conducting performance, and may be used to replace available zinc plating layer. The evaporating condenser made of coiled pipe with the said coating has high heat exchange efficiency and long service life.

A pressure transmitter connectable to a process line provides an output responsive to a pressure in the process line. The transmitter includes a housing having a base with a process end coupled to an interior cavity formed in the housing, a sensor for sensing the pressure and an isolating assembly mounted at the process end of the housing and isolating fluid in the process line from the interior cavity. The isolating assembly includes an isolation diaphragm configured to be fluidically coupled to the process pressure in the process line, and an isolator plug positioned in the process of the housing adapter. The isolator plug having a lower plug portion providing a first end surface adjacent the isolation diaphragm, an upper plug portion providing a second end surface distally spaced from the first end surface and adjacent a sensor cavity in which the sensor is positioned, a connection mechanism connecting the lower and upper plug portions, and a capillary filled with isolation fluid and extending from the first end surface through the lower and upper plug portions to the second end surface thereby coupling the pressure through the isolation diaphragm and the capillary to the sensor cavity and the sensor. The upper plug portion is formed from a first material and the lower plug portion is formed from a second material having higher corrosion resistance than the first material.

A liquid cooling system is disclosed for use in an electronic apparatus. The system is constructed to be of a reduced size and thickness, thus allowing it to be used for cooling heat-generating devices such as semiconductor elements, while maintaining corrosion resistance. The system includes a pump, a heat-receiving jacket, and flow passages through which the cooling liquid is circulated. An ion exchange bag having a water-permeable bag is disposed within the liquid cooling system. The water-permeable bag further contains an ion exchange resin therein.
