A subsystem for an exposure apparatus has at least one array of tilting mirrors placed in either an image reticle plane or a conjugate image plane to provide dynamic control of an illumination beam through an exposure field. In the system, an optical subsystem and a plurality of mirrors directs light to a reticle and a sensor senses the illumination distribution of the light at a wafer stage. When the at least one array of tilting mirrors is placed in the image reticle plane, a control is used to interpolate data of the illumination distribution sensed by the sensor, and then control movement of at least one mirror of the array of mirrors based on the interpolated data.

Selective gas-reducing methods for making shape-defined metal-based nanoparticles. By avoiding the use of solid or liquid reducing reagents, the gas reducing reagent can be used to make shape well-defined metal- and metal alloy-based nanoparticles without producing contaminates in solution. Therefore, the post-synthesis process including surface treatment become simple or unnecessary. Weak capping reagents can be used for preventing nanoparticles from aggregation, which makes the further removing the capping reagents easier. The selective gas-reducing technique represents a new concept for shape control of nanoparticles, which is based on the concepts of tuning the reducing rate of the different facets. This technique can be used to produce morphology-controlled nanoparticles from nanometer- to submicron- to micron-sized scale. The Pt-based nanoparticles show improved catalytic properties (e.g., activity and durability).

[PROBLEMS] To cushion impact acting on an occupant who is not in a regular position. [MEANS FOR SOLVING PROBLEMS] When an abnormality occurs, an airbag device (1) inflates and expands in front of an occupant and absorbs an impact from the front of a vehicle. An airbag (2) to which gas from an inflator is supplied in an abnormality is provided with a vertical recess (2c) facing the head (Ph) of the occupant (P). The recess (2c) is located at the center, in the right and left direction of the vehicle, of an occupant restriction surface (2b) formed at a position facing the occupant (P) sitting on the seat during inflation and expansion. At least one fixed vent (2ea, 2eb) and at least one variable vent (2fan, 2fb) are provided at each of opposite sidewalls (2da, 2db). The fixed vent (2ea, 2eb) has an invariant opening area, and the variable vents (2fan 2fb) has an opening area variable depending on the sitting position of the occupant (P) during expansion. The recess (2c) and the opposite sidewalls (2da, 2db) are coupled in the airbag (2) by shape control members (3a,3b). [EFFECT] Even an occupant of out of position or an occupant not wearing a seat belt can be received relatively flexibly, and trouble caused on the occupant by the airbag is reduced.

A general, reproducible, and simple synthetic method that employs readily available chemicals permits control of the size, shape, and size distribution of metal oxide nanocrystals. The synthesis entails reacting a metal fatty acid salt, the corresponding fatty acid, and a hydrocarbon solvent, with the reaction product being pyrolyzed to the metal oxide. Nearly monodisperse oxide nanocrystals of Fe3O4, Cr2O3, MnO, Co3O4, NiO, ZnO, SnO2, and In2O3, in a large size range (3-50 nm), are described. Size and shape control of the nanocrystals is achieved by varying the reactivity and concentration of the precursors.

Provided is a methodology and system for applying coatings onto the interior surfaces of components. The approach comprises a vapor creation device (for example an electron beam or laser that evaporates a single or multiplicity of solid or liquid sources), a vacuum chamber having a moderate gas pressure (between about 10−4 to about 103 Torr) and a inert gas jet having controlled velocity and flow fields of gas jet. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved (i.e. the gas pressure prior to its entrance into the processing chamber through the nozzle). The carrier gas flow and chamber pumping rate control the downstream (or chamber) pressure (i.e., downstream of the nozzle). The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. The carrier gas molecular weight (compared to that of the vapor) and the carrier gas speed controls its effectiveness in redirecting the vapor atoms via binary collisions towards the substrate. The speed and flux of the atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all vary leading to a wide range of accessible processing conditions. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. Under certain process conditions these collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit.
