A suspending hydraulic pillar includes an oil cylinder, a movable prop, a handle-valve body, a reset spring, a top cover, a bottom seat, a three-way valve, a position-limiting steel wire, and a guide ring. The handle-valve body is provided between a port of the oil cylinder port and the moveable prop. Position-limiting steel wire, a guiding ring, and an oil inlet is located on a lower part of the moveable prop. The three-way valve is provided in the handle-valve body. A dust-prevention ring and a sealing ring are provided between the handle-valve body, the movable prop, and the oil cylinder. The handle-valve body is fixed on the oil cylinder by means of a connecting steel wire. The handle-valve body does not move up and down as the movable prop telescopically extends or contracts. The suspending hydraulic has good stability, high strength and supporting force, good sealing, and high anti-erosive capability.

Embodiments of the present invention disclose a relay method of a transport bearer, an apparatus and a communication system. According to the technical solutions in the present invention, when receiving information encapsulated by a source device and sent by the source device, a relay base station first decapsulates the information, encapsulates the information again, and then sends the encapsulated information to a host device, thus ensuring that the information has only a layer of encapsulation in the transport procedure, so as to avoid a case that a high overhead caused by two layers of encapsulation occurs in the transport procedure. Compared with the prior art, the overhead in the transport procedure may be reduced, and the transport efficiency may be increased.

A method for manufacturing a thin semiconductor package includes providing a lead frame with a removable substrate that has an attaching surface attached to a first surface of the lead frame. The lead frame is formed from an electrically conductive sheet and has leads that extend inwardly from a lead frame boundary towards a central region of the lead frame. A semiconductor die is mounted on the removable substrate at the central region. The semiconductor die has a connection pad surface with die pads on it, and the connection pad surface is attached to the attaching surface of the removable substrate. The lead frame and die are encapsulated with a first encapsulant so that the lead frame is sandwiched between the first encapsulant and the removable substrate. The removable substrate is removed from the lead frame to expose the first surface of the lead frame and then the die pads are electrically connected to respective ones of the leads. The die and lead frame then are encapsulated with a second encapsulant so that the lead frame and die are sandwiched between the first and second encapsulants. Part of the first encapsulant is then removed to reduce the thickness of the package and expose the leads.

A method for realizing data forwarding, a network system, and a related device are provided. The method includes: receiving data sent from an external device; and judging whether the data is from or to a backhaul terminal, and directly forwarding the data if the data is from or to the backhaul terminal. A Base Station (BS) device includes: a receiving module, configured to receive data sent from an external device; a backhaul judging module, configured to judge whether the data is from or to a backhaul terminal; and a sending module, configured to directly forward the data after the backhaul judging module judges that the data is from or to the backhaul terminal. A backhaul terminal and a network system are further correspondingly provided. Accordingly, transmission bandwidth is saved through the provided technical solutions.

A single longitudinal-mode laser includes a first mirror and a second mirror that define a laser cavity therein that does not include a linear polarizer. A birefringent gain medium can generate a lasing light at a lasing wavelength along a light propagation direction in response to a pump light at a pumping wavelength. The birefringent gain medium has an optical axis substantially perpendicular to the light propagation direction. A first wave plate positioned between the first mirror and the birefringent gain medium is a quarter wave plate at the lasing wavelength and a whole wave plate at the pumping wavelength. A second wave plate is positioned between the birefringent gain medium and the second mirror. The first wave plat and the second wave plate in part produce a single longitudinal mode in the lasing light.
