Abstract:
An inflatable product includes an inflatable body and an electric pump for pumping the inflatable body. The electric pump includes a pump body and an air outlet, wherein the pump body is wholly or partially recessed into the inflatable body and permanently held by the inflatable body. Preferably, the electric pump includes a fan and a motor connected to the fan, and the fan is rotated by the motor in a first direction to pump the inflatable body or in a second direction opposite the first direction to deflate the inflatable body.
Abstract:
An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.
Abstract:
A method for preparing hexose derivatives comprises the steps of providing a silylated hexose, treating the silylated hexose with a first carbonyl compound in the presence of a catalyst to form an ketalized hexose, treating the ketalized hexose with a second carbonyl compound followed by treating with a first reductant to form an etherized hexose, and converting the etherized hexose into a target hexose derivative, which can be 2-alcohol hexose, 3-alcohol hexose, 4-alcohol hexose, or a 6-alcohol hexose. In particular, the present invention can prepare the hexose derivatives with highly regioselective scheme to protect individual hydroxyls of monosaccharide units and install an orthogonal protecting group pattern in a one-pot manner
Abstract:
An inflatable product that includes a chamber and an electric air pump for inflating the chamber. The air pump has an air intake and an air outlet. The air intake is connected to the outside of the chamber and the air outlet is connected to the inside of the chamber when the air pump is moved to a first position. The air intake is connected to the inside of the chamber and the air outlet is connected to the outside of the chamber when the air pump is moved to a second position.
Abstract:
An inflatable product includes an inflatable body, a socket, an electric pump and a battery case. The socket is built in the inflatable body. The electric pump is detachably connected to the socket to pump the inflatable body. The battery case is also built in the inflatable body for receiving batteries to supply the electric pump with power.

Abstract:
A chemical vapor deposition (CVD) method for forming a microelectronic layer provides a source material dispensing nozzle employed within a chemical vapor deposition (CVD) apparatus which is employed within the chemical vapor deposition (CVD) method. The source material dispensing nozzle is calibrated to provide a calibrated source material dispensing nozzle. The calibrated source material dispensing nozzle is employed within the chemical vapor deposition (CVD) apparatus while employing the chemical vapor deposition (CVD) method for forming a chemical vapor deposition (CVD) deposited microelectronic layer upon the substrate positioned within the chemical vapor deposition (CVD) apparatus.

Abstract:
An inflatable product that includes an inflatable body, a switching pipe and a fan and motor. The switching pipe is switched between a first position and a second position. The fan and motor inflates the inflatable body when the switching pipe is switched to the first position. The fan and motor deflates the inflatable body via the switching pipe when the switching pipe is switched to the second position.
Abstract:
An inflatable product includes an inflatable body, a socket built in the inflatable body, and an electric pump. The electric pump includes a pump body and an air outlet, connected to the socket to pump the inflatable body, wherein the pump body is wholly or partially located in the socket. A connector may be provided at a predetermined position of the electric pump for connecting an external power to actuate the electric pump.
