摘要:
A canister comprises a vessel defining a volume and an opening having a rim and a lid. The lid comprises a flexible bulb and a conformal outer edge configured to create an airtight vacuum seal with the rim to close the opening. The flexible bulb is configured to release pressure from the vessel and break the airtight vacuum seal in response to compression of the bulb. The lid can be configured to be completely contained within the rim.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for control of beverage dispensing. In one aspect, authorization data specifying that a beverage dispensing node is authorized to be activated are received. Activation data that request activation of the node are also received, where activation of the node causes a valve that controls flow of fluid to a beverage dispenser to be opened. A determination is made that the activation data are associated with a user identifier for an enabled user, where an enabled user is a user that has been enabled to activate the node. In response to receipt of the authorization data and the activation data a valve that controls flow of fluid to the beverage dispenser is opened. Data (e.g., de-authorization or de-activation data) specifying that an activated beverage dispensing apparatus be de-activated can also be received. In response to receipt of the data, the valve can be closed.

Methods and systems to optimize wafer placement repeatability in semiconductor manufacturing equipment using a controlled series of wafer movements are provided. In one embodiment, a preliminary station calibration is performed to teach a robot position for each station interfaced to facets of a vacuum transfer module used in semiconductor manufacturing. The method also calibrates the system to obtain compensation parameters that take into account the station where the wafer is to be placed, position of sensors in each facet, and offsets derived from performing extend and retract operations of a robot arm. In another embodiment where the robot includes two arms, the method calibrates the system to compensate for differences derived from using one arm or the other. During manufacturing, the wafers are placed in the different stations using the compensation parameters.
摘要:
A nano-particle composition including a poly(alkenylbenzene) core and a poly(conjugated diene), a poly(alkylene), or a poly(alkenylbenzene) surface layer is provided. The nano-particles have a mean average diameter of less than about 100 nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can be advantageously be incorporated into rubbers, elastomers, and thermoplastics.
摘要:
The invention provides a sulfur vulcanizable silica-reinforced elastomeric compound having improved tensile mechanical and dynamic viscoelastic properties. The compounds are formed by mixing an elastomer optionally having an alkoxysilane terminal group, with silica in the presence of an alkyl alkoxysilane and a blocked mercaptosilane. In particular, the mercaptosilane moiety of the blocked mercaptosilane and the alkyl alkoxysilane are present in a weight ratio of about 0.001:1 to about 0.20:1. Preferably, the blocked mercaptosilane and the alkyl alkoxysilane are compounded with the elastomer and the silica at high temperature to facilitate the silica-silane reaction. A deblocking agent is added at any desired mixing stage, optionally with the cure package, to allow binding of the mercaptosilane to the polymer.

A bandage application system of the present for hemorrhage control and/or tissue repair of the gastrointestinal tract, such as the gastrointestinal tract is provided. The system comprises a bandage for hemorrhage control and/or tissue repair of the gastrointestinal tract. It also includes an apparatus for introducing the bandage into a treatment area of the gastrointestinal tract requiring hemorrhage control and/or tissue repair, and for removing the apparatus from the treatment area without displacing the bandage from being adhered to the treatment area, and without damaging the gastrointestinal tract. Furthermore, it also has a device for adhering the bandage to the treatment area.
摘要:
The present invention relates to a method for treating liver cancer or oral cancer through photodynamic therapy, comprising administrating a subject in need thereof an effective amount of formula I, formula □, formula III or formula IV, which could release reactive oxygen species to inhibit the growth of cancer cells, which comprise with formulas as described in the specification, wherein R1 is an alkyl or an aldehyde with carbon atoms no more than 2; the cancer is liver cancer or oral cancer.
