摘要:
An illumination optical system for, when installed in an exposure system, realizing a suitable illumination condition by varying the polarized state of the illumination light according to the pattern characteristics of the mask while suppressing the loss of the intensity of the light. The illumination optical system has a light source unit for supplying a linearly polarized light for illuminating surfaces to be illuminated therewith, and a polarized state changing device for changing the polarized state of the illuminating light from a predetermined polarized state to a nonpolarized state and vice versa. The polarized state changing device is arranged in the optical path between the light source unit and the surfaces to be illuminated. The polarized state changing device can be removed from the illumination optical path and has a depolarizer for selectively depolarizing the incident linearly polarized light.

A memory card socket structure includes an arm rotatably moved by an insertion and an extraction of a memory card into and from a card compartment and a memory card detecting function for detecting whether the memory card is inserted into the card compartment. The arm includes a main portion to be in contact with the memory card and a sub portion disposed opposite to the main portion with respect to a rotation shaft thereof, and is located at a rear side of the card compartment. The arm is engaged with a torsion spring whose first end portion is engaged with a first stationary contact but whose second end portion is engaged with the sub portion, whereby the main portion is biased by the spring toward an entrance of the card compartment.

Provided is a pressure coupling connector which can decrease the number of components for coping with various electric wire diameters, prevent problems due to difference in product kind, and reduce the stock. The pressure coupling connector includes a wire holding block for holding electric wires and a contact block for holding a connection terminal to which the electric wire is coupled with pressure by inserting the wire holding block into the contact block. The connection terminal of the contact block includes a U-shaped blade rising toward an opening surface into which the wire holding block is inserted. The wire holding block includes a wire holding portion in which a holding hole for transmitting the electric wire from the rear side thereof and holding the electric wire is formed and a reception groove for receiving the U-shaped blade of the connection terminal. The U-shaped blade of the connection terminal includes a core pressing blade having a step-shaped slit with two different widths in the vertical direction and a wire holding blade having a step-shaped slit with two different widths in the vertical direction, sequentially from the inside in an electric wire insertion direction. Adapting to the outer shape of an electric wire, the electric wire can be held with a wire holding slit (upper step portion) 53a or a wire holding slit (lower step portion) 53b.

An exhaust gas-purifying catalyst includes a carrier, and an active component formed of a noble metal, carried by the carrier. The carrier has a core portion comprising a cubic or tetragonal stabilized zirconia-based composite oxide containing at least one stabilizing element, and a surface layer portion including a heat resistant zirconia-based composite oxide formed on a surface of the core portion. The surface layer has a specific surface area which is larger than a specific surface area of the core portion. A part of the noble metal is solid-solutioned into the zirconia-based composite oxide of the surface layer portion, and the balance of the noble metal is carried on a surface of the surface layer portion.
