The invention discloses a heat-type wind-speed and wind-direction sensor with a heat insulation structure, comprising a silicon chip and a ceramic substrate, wherein the silicon chip is positioned above the ceramic substrate; four heating elements and four heat-sensing temperature-measuring elements are symmetrically distributed on the four edges of the upper surface of the silicon chip; a heat insulating groove is arranged between each heating element and each heat-sensing temperature-measuring element; heat insulating cavities are arranged below the heat-sensing temperature-measuring elements at the back of the silicon chip; and a ceramic gold-plating layer and a silicon gold-plating layer are arranged between the silicon chip and the ceramic substrate and are connected by adopting a gold-gold bonding process so as to be used for the heat connection between the silicon chip and the ceramic substrate. In the whole preparation process of the sensor, a standard CMOS (complementary metal-oxide-semiconductor) process is used, the after-treatment process is simple, and the prepared heat-insulating groove and the heat insulating cavities can be used for increasing the sensitivity of the chip effectively, reducing the heat conduction loss of the chip and the heat capacity of the sensor, and reducing the response time of the sensor.

A thin fan comprises a fan frame and a blade assembly accommodated in the fan frame. The fan assembly comprises a hub, a blade ring structure around the hub and a plurality of blades clamped on the blade ring structure, and the blades are made of magnesium and aluminum alloy. The thickness of the fan is reduced greatly as compared with that of the prior art, so that the thin fan has larger air intake space and high in airflow and cooling effect of the thin fan is guaranteed. Besides, since the blades of the fan are thinned, the integral size of the blades is reduced, and weight of the blades is lower than that of existing plastic blades. Further, due to excellent performance of the magnesium and aluminum alloy blades, stress of the blades is improved, the blades are not easy to deform. In addition, since interference between the blades and a top cover is avoided, stability of the thin fan is improved.

Methods and structures for producing semiconductor materials, substrates and devices with improved characteristics are disclosed. Structures and methods for forming reduced strain structures include forming a plurality of substantially strain-relaxed island structures and utilizing such island structures for subsequent further growth of strain-relaxed substantial continuous layers of semiconductor material.

A negative electrode mixture is provided and includes: a negative electrode active material containing a carbon based material; a binder containing at least a polyacrylonitrile based resin; and a polymer capable of suppressing an intermolecular interaction between cyano groups and imparting a steric hindrance.

A molten glass supply device is provided, which can solve unavoidable problems for high viscosity characteristics in connection with the conventional molten glass supply device for high viscosity glass. Such problems include improperly high heating cost caused by excessive heat radiation in a melting furnace, reduction in the grade of products deriving from an excess amount of an erosion foreign material and reduction in the product yield. High viscosity molten glass having a property in which a temperature at which the molten glass exhibits a viscosity of 1000 poise is 1350 DEG C. or higher is supplied to a forming device through a melting furnace, a distribution portion in communication with the outlet of the melting furnace, and a plurality of branch paths branching from the distribution portion. In the branch paths, distribution resistance providing portions that provide distribution resistance to molten glass passed through the branch paths are provided. The supply pressure of the molten glass is equalized when molten glass is distributed from the distribution portion to the branch paths. The distribution portion has a shallower bottom than the melting furnace.

Disclosed are an open-porous metal foam and a method for manufacturing the same. An open-porous metal foam according to an exemplary embodiment of the present invention is made of an iron-based alloy including 15 wt % or more of chrome and 5 wt % or more of aluminum. The open-porous metal foam is a semi-product that is formed of iron or the iron-based alloy that does not include chrome and aluminum or includes a smaller amount of chrome and aluminum in the powder when manufacturing, and the surface and the open pore thereof are uniformly coated with the powder of the iron-chrome-aluminum alloy and the organic binding agent. When heat treatment is performed under a reduction atmosphere, sintering is performed. In this case, the metal foam body that is formed of the iron-chrome-aluminum alloy is obtained by compensating concentrations of alloy elements between the semi-product and the powder by diffusion, and a content of chrome and aluminum in the metal foam is smaller than a content of chrome and aluminum included in a starting alloy of the used powder.
