20150368072 | LARGE-TONNAGE SLENDER EXTERNALLY POWERED CURVE RAIL-MOUNTED UNLOADING SKIP - The present invention provides a large-tonnage slender externally powered rail-mounted unloading skip, comprising an upper bin body and a lower bin body that are respectively formed by an inner lining plate and an outer plate fixed together via a number of pin shafts, a self-locking gate, and a gate opening device. A loading opening and a coal baffle plate that is used to block coal when the coal is loaded are arranged on the upper part of the upper bin body, a self-locking gate composed of a sector gate plate and unloading rollers is arranged on the lower bin body, a coal chute is arranged on the lower part of the self-locking gate, the upper bin body and the lower bin body are connected together through flanged connection, and channel irons are welded around the walls of the upper bin body and lower bin body respectively; when the skip is at an unloading position, externally powered telescopic push rods push the unloading rollers to move in an unloading rail of the slide block, so that the self-locking gate is opened, and the coal is unloaded along a coal chute. With the reliable connection between the upper bin body and the lower bin body, effective and convenient fixing of the lining plate, and reliable opening of the gate, the skip can meet the production requirements of 10-million tonnage large-size shafts. | 12-24-2015 |

20140339709 | HIGH POWER DIELECTRIC CARRIER WITH ACCURATE DIE ATTACH LAYER - A system for bonding a die to a high power dielectric carrier such as a ceramic dielectric core with double-sided conductive layers is described. In the system, the upper conductive layer has a first area whose surface has a first wettability. A second area that at least partially surrounds the first area has a surface with a second wettability that is greater than the first wettability. During bonding, an adhesive material bonding a chip to the substrate spreads among the first area by a downward force placed on the chip. Due to the difference in wettability, the adhesive material then spreads among the second area by a wetting force generated by the greater second wettability of the second area surface causing the chip to be drawn down until reaching a predetermined position. The predetermined position can be determined by substrate protrusions or substrate cavities. | 11-20-2014 |
20150016078 | Partitioned Hybrid Substrate for Radio Frequency Applications - The presently claimed invention is to provide a package for compact RF signal system, and a method to form the package thereof in order to miniaturize the size of package, improve signal integrity, and reduce manufacturing cost. The package comprises a hybrid substrate with a sandwiched structure, in which the hybrid substrate comprises an upper layer and a lower layer with different dielectric properties being separated by an interposer for improving electrical isolation and mechanical stiffness. Metal layers are formed on the sidewalls of the opening to surround an active component, such that the metal sidewalls together with two ground plates in the upper and lower layers constitute a self-shielding enclosure inside the package to protect the active component. | 01-15-2015 |

20150314773 | TORQUE DISTRIBUTION METHOD FOR ENGINE AND MOTOR OF ENERGY-EFFICIENT HYBRID ELECTRIC VEHICLE - A torque distribution method for an engine and a motor of an energy-efficient hybrid electric vehicle comprises the following steps: providing an offline specific fuel consumption map of the engine in all operating states; enabling the engine and motor to respond to the required torque T during travelling together, the motor and the engine working in cooperation at the same rotational speed so as to achieve the optimal working efficiency; acquiring a current state of charge (SOC) of the vehicle battery, and distributing the engine torque T and the motor torque T according to the following situation: if the SOC is greater than a first preset value, entering a first distribution mode; if the SOC is less than a second preset value, enter a second distribution mode; and otherwise, maintaining the current working state. The method can fully utilize the performance advantage of the engine and that of the motor, so that the system works at high efficiency all the time, thereby decreasing the energy consumption of the vehicle, greatly reducing harmful emission, and facilitating energy conservation and environmental protection. | 11-05-2015 |
