The present invention relates to novel polymeric compositions that exhibit Reverse Thermal Gelation (RTG) properties for use as Support Materials (SM) in the manufacture of three-dimensional objects. These polymers are Temperature Sensitive Polymers that respond with a significant change of properties to a small change in temperature. Temperature Sensitive Polymers exhibit cloud point (CP) or lower critical solution temperature (LCST) in aqueous solutions. Water-soluble Temperature Sensitive Polymers are chosen to give low viscosity liquid at low temperature when dissolved in water and by that to permit easy dispensing at low temperature. Raising the temperature above their gelation temperature (T_gel) will result in solidification of the composition. At its gel position the material has favorable characteristics as a support and building material. The gel layers have the appropriate toughness and dimensional stability to support the model layers during the building process. After the building process is completed the gel can be cooled down to a temperature below its T_gel so the gel can liquefy and be removed easily by rinsing with water.

A method of minimizing stress in an OLED device laser sealing process using an elongated laser beam. A laser beam having an intensity distribution which decreases as a function of distance from the longitudinal axis of the beam is passed through a mask to create an elongated beam having a length-wise intensity distribution which decreases as a function of distance from the axis of the beam and a substantially constant width-wise intensity distribution. The elongated beam is traversed over a line of frit disposed between two substrates. The tails of the length-wise intensity distribution provide for a slow cool down of the frit as the beam traverses the line of frit.

A component box has a shape of a substantially flat plate, and is stacked along a direction UPR toward the ceiling of a vehicle with its center placed at a central portion of a casing for a battery pack. Cooling wind which has been used for air-conditioning inside the vehicle and supplied from a cooling fan to the battery pack is supplied to a coolant introducing space located on an upper side of a module, passes through a gap between adjacent battery groups to flow down to a lower side of the battery groups, and then is emitted from a coolant lead-out space located at a lower side of the module out of the battery pack. Since the component box is in contact with a cooling wind passage with the casing therebetween, the component box in contact with the cooling wind via the casing is cooled down simultaneously with the cooling of the module. Since the component box is placed with its center positioned at the central portion of the battery pack, variations in temperature among batteries can be suppressed.

A method and apparatus that is useful for forming a high quality gate dielectric layer in MOS TFT devices using a high density plasma oxidation (HDPO) process. The HDPO process forms a good interface and then a second layer, which has good bulk electrical properties, is deposited at a higher deposition rate over the HDPO layer. In one embodiment a thin HDPO process layer is formed over the channel, source and drain regions to form a high quality dielectric interface and then one or more dielectric layers are deposited on the HDPO layer to form a high quality gate dielectric layer. The HDPO process generally entails using an inductively and/or capacitively coupled RF energy transmitting device to generate and control the plasma generated over the surface of the substrate and injecting a gas containing an oxidizing source to grow the interfacial layer. A second dielectric layer may then be deposited on the surface of the substrate using a CVD or plasma enhanced CVD deposition process. Aspects of the present invention also provide a cluster tool that contains at least one specialized plasma processing chamber that is capable of depositing a high quality gate dielectric layer. The cluster tool is advantageous because it supports both the pre-processing steps, such as, preheating the substrate, pre-cleaning the surface of the substrate prior to processing, and cool down after processing, all in a single controlled environment.

On the premise that a target torque of an engine is equal to 0, that observed catalyst temperature is in a specified temperature range causing deterioration of the catalyst, and that the engine runs idle without a fuel cut regardless of fulfillment of preset fuel cut conditions, the control procedure of the invention determines whether a predetermined engine stop condition is fulfilled (step S300). Upon fulfillment of the predetermined engine stop condition, the control procedure subsequently determines whether a high load is applied to an exhaust catalyst (step S320). The engine runs idle (step S310) when a high load is applied to the exhaust catalyst. The relatively low-temperature exhaust gas from the engine in the idling state forcibly cools down the exhaust catalyst. This prevents the exhaust catalyst from being kept at high temperature. When a low load is applied to the exhaust catalyst at step S320, on the other hand, the engine is stopped (step S330). The stop of the engine cuts off the air flow through the exhaust catalyst. The exhaust catalyst is thus not exposed to the lean exhaust atmosphere and does not significantly deteriorate even at high temperature.

This invention provides a closed-loop cycling type heat-dissipation apparatus, including at least one metal conduit and plural heat-dissipation fins. Hot air in a housing of a screen module is channeled into the metal conduit through an upper exit of the housing. Heat-dissipation fins attached onto the metal conduit then make heat exchange with atmosphere. The heat of the hot air is dissipated to atmosphere by thermal convection or thermal radiation of surfaces of the heat-dissipation fins. The hot air is cooled down and then channeled into the housing of the screen module through a lower entrance thereof. A closed-loop heat-dissipation cycle is formed. Inner temperature of the housing and temperature difference between inner part and outer part of the housing are effectively lowered. The present apparatus can provide a capability sufficient for heat-dissipation while without the aid of other baggage. The heat-dissipation is relied on nature heat-dissipation cycle in a system and without thermal convection between air in the system and atmosphere.
