The invention provides a radiating packaging structure of a semiconductor power device. The radiating packaging structure of the semiconductor power device is provided with a radiating shell body containing cooling liquid, wherein the inner side of a cover plate of the radiating shell body is provided with radiating assemblies and further forms a fluid flow passage, and meanwhile the other side of the cover plate serves as a substrate of the semiconductor power device, namely, the radiating packaging structure and the semiconductor power devices are integrally formed, so the structure is very compact. The radiating packaging structure is characterized in that due to the integrated packaging structure, heat resistance produced by silica gel with a low heat conductivity coefficient is avoided, the radiating assemblies are located on the other side (namely the substrate) of the cover plate, heat from the power device can be directly dissipated, and meanwhile, the radiating effect of the semiconductor power device is greatly improved under the action of turbulent flow of the radiating assemblies.

A pneumatic tire having a runflat capability provided with a crescent shaped reinforcing rubber layer at the side part thereof, wherein an inner layer is composed of a thermoplastic elastomer composition containing (A) at least one thermoplastic resin having an air permeation coefficient of 100×10−12 cc·cm / cm2·sec·cmHg or less and a Young's modulus of more than 500 MPa and (B) at least one elastomer ingredient having an air permeation coefficient of 50×10−12 cc·cm / cm2·sec·cmHg or more and a Young's modulus of 500 MPa or less in amounts of at least 30% by weight based upon the total polymer ingredients and having an air permeation coefficient of 100×10−12 cc·cm / cm2·sec·cmHg or less.

The invention provides a packaging structure of an integrated power control unit. Heating elements are not distributed according to a traditional functional module. All the heating elements are distributed in a scattered mode. The problems of the use conditions, power and the like of the heating elements achieving the same function and different functions are comprehensively considered, the heating elements achieving the same function are distributed on a main substrate at intervals, the heating elements achieving the different functions are also distributed on the main substrate at the same time, and therefore under the different use conditions, the heating quantities of different areas on the whole main substrate are even to the great extent. On the one hand, even heating provides the powerful guarantee for even heat dissipation, on the other hand, the simplification of the integrated heat dissipation structure is facilitated, and then the packaging structure is beneficial to meeting the small-size requirement of the control unit. Meanwhile, the even heating is also beneficial to improving the use stability of the main substrate and prolonging the service life of the main substrate.

The invention discloses a three-dimensional drying device. The three-dimensional drying device comprises a drying room. A plurality of supporting stand columns are arranged in the drying room. A plurality of layers of transverse supporting frames are arranged between the supporting stand columns in an up-and-down side-by-side mode. A main transferring frame with a chain wheel transmission system is fixed on each layer of transverse supporting frame. Lifting transferring frames with chain wheel transmission systems are arranged on the outer sides of the two ends of the upper and lower layers of adjacent transverse supporting frames in a crossed mode. Each lifting transferring frame is connected with a lifting mechanism, wherein the lifting mechanism can drive the corresponding lifting transferring frame to lift between the upper and lower layers of adjacent transverse supporting frames and is drawn close to and flush with the corresponding main transferring frame at the lifting route tail end. The three-dimensional drying device has the beneficial effects that dried workpieces are transferred by using a three-dimensional circulating mode, the distance of workpiece running is greatly prolonged in a limited space, so that the workpieces make fully and evenly contact with indoor dried air, the drying efficiency is improved, the drying uniformity is also improved, spaces are saved, the degree of automation is high, and the manual labor intensity is reduced.

A hybrid vehicle includes an engine, a first rotating electrical machine (first MG), a second rotating electrical machine (second MG), a planetary gear mechanism which mechanically couples these devices, a first inverter which drives the first MG, a second inverter which drives the second MG, and a controller. When the controller receives a fail signal from the first inverter, the controller performs shut-down control which brings the first inverter into a gate shut-down state with fuel supply to the engine being stopped. When the absolute value of an engine rotation speed Ne is more than or equal to a predetermined value α and the absolute value of a rotation speed Nm1 of the first MG is less than a threshold value β after the shut-down control is started, the controller determines that the first inverter has a short-circuit fault.

A method for manufacturing a golf club head includes aging heat treat a sheet material made of a titanium alloy at 650-750° C. for 10-12 hours to obtain an aging heat treated sheet material. The aging heat treated sheet material is hot rolled to form a striking plate. The striking plate is annealed at 700-800° C. for 30-60 minutes to obtain an annealed striking plate. The annealed striking plate is welded to a club head body made of the titanium alloy to form a semi product. The semi product of the golf head is annealed at 500-700° C. for 30-240 minutes to obtain the golf club head. Thus, the golf club head with a Young's modulus higher than 119 GPa can be manufactured.
