This invention relates to electronic baseplate by low-temperature co-sintering of aluminium nitride / borosilicate glass. This baseplate is composed of: AlN 30-70%; oxides 30-70%. Said oxides are then composed (by mol percentages) of: SiO2 8-12%, B203 18-24%, ZnO 45-60%, Al203 3-8%, Li20 3-8%. This inventive product has excellent comprehensive properties, its heat conductivity is increased from that of prior art product 2-5 W / m.K to 10W / m.K. It can be used in more greater power devices with excellent dielectric property. This invention has also advantages of: easily available raw materials, low cost, simple process.

The invention discloses a telegraph pole crusher comprising a support, wherein the front end of the support is provided with four telegraph pole conveying rack supports and four telegraph pole conveying racks supported on the four telegraph pole conveying rack supports, and a support retraction oil cylinder is arranged below each telegraph pole conveying rack support; four corners positioned at the lower side of the support are symmetrically provided with four mechanical hydraulic supports and four tyres; the rear end of the support is provided with a mechanical towing bracket for facilitating towing of equipment; a crushed material conveying belt A and a crushed material conveying belt B are arranged below the support; a crushed material conveying rack lift oil cylinder and a crushed material conveying rack folding oil cylinder are arranged below the crushed material conveying belt A and the crushed material conveying belt B; the support is sequentially provided with a vibrating hammer A, three groups of compression rollers, i.e. a compression roller group A, a compression roller group B and a compression roller group C, and a vibrating hammer B from front to back; and a vibration reduction platform is arranged below the vibrating hammer B. According to the telegraph pole crusher disclosed by the invention, a design structure is simple, flexible and light so that the positionof integral crusher can be freely moved with an environment, and therefore, an occupied space is reduced, convenience and high efficiency are achieved when in use, and labor intensity is greatly reduced.

The embodiment of the invention relates to the field of wireless communication technology, and discloses an antenna switch device and a terminal thereof. The antenna switch device comprises at least one switch circuit, the switch circuit comprises: a first matching circuit, a second matching circuit, a first capacitor element, a second capacitor element, a first gating element, a second gating element, a first control transmission circuit and a second control transmission circuit, wherein when a first end of the first control transmission circuit receives a first control signal, the first gating element is in a turn-on state under the control of the first control signal, and when the first end of the second control transmission circuit receives a second control signal, the second gating element is in a disconnected state according to the second control signal. In the antenna switch device disclosed by the invention, the flexibility of the antenna switch circuit of the terminal is improved, and meanwhile better performance of the antenna switch is guaranteed.
