摘要:
A transmission frame structure for use in a control communication network allows all process control stations contained in the control communication network to share monitoring/control information received from a field communication network or an information communication network, and properly copes with faulty operations of channels (i.e., ring-shaped lines) or process control stations for use in the control communication network. The transmission frame structure of a control communication network for use in a nuclear-power-plant distributed control system which broadcasts data received from a node having transmission authority to all nodes via a bypass line, and allows a ring accelerator to detour the data and to isolate an erroneous station from normal stations, includes a transmission frame. The transmission frame includes: a destination address for performing the broadcasting operation; a source address for recording a source node address (ID) therein; a type/length field for classifying frames into a control data frame and a network management event frame; a network management (NM_TYPE) field which is valid only when it is designated by type/length field, and performs different roles according to network management event frame types; a Seq&Ver field for including the number of transmissions of a data frame and frame upgrade version information; a NS_ID field for recording number information of a node equal to the next token reception node, and being used when one station transmits a token to the next station; a data field having a predetermined maximum size of 1 kbyte, for including not only general control information according to a value of the type/length field, but also 7 event frames such as a token frame; and a CRC (Cyclic Redundancy Code) field for inspecting the presence or absence of a CRC error, whereby the transmission frame operates the communication network, solves a malfunction or error of the communication network, and recovers the communication network.

Disclosed herein are a liquid composition for immersion lithography and a lithography method using the composition. The liquid composition includes at least one nonionic surfactant selected from the group comprising of a polyvinyl alcohol, a pentaerythritol-based compound, a polymer containing an alkylene oxide, and a compound represented by Formula I: wherein R is a linear or branched, substituted C1-C40 alkyl, and n is an integer ranging from 10 to 10,000. The surface tension of the liquid composition is reduced by the nonionic surfactant, thereby solving the problem that the liquid composition is not completely filled or is partially concentrated on a wafer having a fine topology and removing micro bubbles between the photoresist film and the liquid composition.

摘要:
A breast pump includes a pump that produces both vacuum and pulsating pressure, at least one express kit, and hoses or the like for connecting the pump to the express kit. The express kit includes a manifold, a milk collection vessel, a rigid cup and a flexible liner. The liner is made of a pliable material, and includes a funnel and a throat. The inside surface of the funnel, which is between the liner and the cup when the liner is installed, has an optional honeycomb structure that creates a forced space between the liner and the cup, while maintaining some degree of flexibility. At the end of the liner inside the throat, a rigid insert or suitable bond maintains some rigidity inside the throat, supports the liner and creates a seal between the liner and the cup at the throat end of the liner.
摘要:
An air circuit is disclosed that communicates with a cycling, bi-directional or intermittent pressure source, splitting the output of the pressure source into two channels. One channel continues to cycle bi-directional or intermittent pressure, and a second channel employs a one-way valve allowing output of vacuum only. In one embodiment, this circuit can be used to actuate unidirectional, pulsating human breast milk expression devices that use vacuum to draw milk, while massaging the breast with pulsating pressure. The air circuit preferably includes an additional one-way valve, which is located upstream of the one-way negative pressure valve, for relief of excess positive pressure within the circuit. The negative channel output of the air circuit can contain a pressure regulation apparatus for end-user control of negative pressure to the expression devices.

摘要:
A hermetic compressor, in which a plurality of oil slots are formed on a bearing seat that seats a thrust bearing therein. During an operation of the hermetic compressor, oil flows through the plurality of oil slots while hydraulically supporting a lower surface of the thrust bearing upward. Therefore, even when an impact is applied from a piston to a rotating shaft during a refrigerant compressing operation of the piston in a compression chamber, the impact load imposed on the thrust bearing is evenly distributed along a junction between a lower race and all balls of the thrust bearing, because the oil hydraulically supports the lower race of the thrust bearing upward. The thrust bearing thus smoothly rotates and effectively supports the rotation of an eccentric part of the rotating shaft. Therefore, the hermetic compressor reduces vibration of the balls and the lower race of the thrust bearing, and attenuates noise caused by the vibration. The hermetic compressor further has improved operational efficiency.
