摘要:
An exposure apparatus for exposing an exposure member or wafer to a pattern with radiation in a step-and-repeat manner thereby to transfer images of the pattern onto different regions on a surface of the exposure member. The apparatus includes an XY stage for moving the wafer in X- and Y-directions, a .theta. stage for moving the wafer in a rotational direction relative to the XY stage, laser interferometers for measuring an amount of movement of the wafer by the XY stage, in each of the X- and Y-directions, by use of a mirror member mounted on the .theta. stage, and a carriage for carrying the XY and .theta. stages and a portion of the interferometers to move the wafer relative to an exposing system for effecting the scan-exposure on the region of the wafer. The mirror member is placed on the .theta. stage, and another portion of the interferometers is mounted on a fixed system independent of the carriage. The inclination of the mirror member is detected at any desired time by moving the carriage and calculating the inclination from the amount of movement of the carriage and the amount of displacement of the mirror member measured by the interferometer mounted on the fixed system. Based on the thus detected inclination of the mirror member, the inclination is corrected and the stepwise movement of the XY stage can be performed with a higher accuracy, so that the transfer accuracy between the pattern images printed on the wafer in the case of the step-and-repeat exposure can be highly improved.

A method of and an apparatus for adsorbingly fixing a body, such as a photomask (mask) or a wafer to a chuck, effect a preliminary vacuum-adsorbing step of preventing the creation of internal stress due to the temperature change between the body and the chuck before the final vacuum adsorption is effected, or effect a preliminary vacuum releasing step for relieving the created internal stress.

A scanning exposure apparatus includes an illumination optical system for illuminating a pattern on a mask using arc-shaped illumination light, a projection optical system for projecting the pattern on the mask illuminated by the illumination optical system onto a plate, a mask stage for scanning the mask, a plate stage for scanning the plate, the scanning exposure apparatus scanning the mask stage and plate stage synchronously relative to the projection optical system, a mask support mechanism for supporting a periphery of the mask, and a mask stage tilt mechanism for arranging the pattern in an area illuminated by the arc-shaped illumination light in an object-surface-side focal plane of the projection optical system, wherein the mask deforms due to its own weight from the peripheral support.

A massage device capable of applying favorable pressure stimulation owing to expansion and shrinking of air bags irrespective of thickness of portions to be massaged such as legs or arms. The massage device has supporting bodies, strap bodies made of pliable material that are attached to the supporting bodies at their ends to form U-shaped sections, air bags provided at inner surfaces of strap bodies for receiving portions of a human body such as legs or arms to be massaged, and an air supply means for expanding and shrinking of the air bags. Upon locating portions to be massaged on the strap bodies, the strap bodies assume shapes that fit along the shapes of the portions of the body to be massaged to thus support the portions to be massaged on the strap bodies. Pressuring stimulation can then be applied to the portions to be massaged by making the air bags perform expansion and shrinking.

A chair type massage machine that enables a massager to effectively perform massages, ensures safety, reduces costs, and allows for easy attachment and removal of a cushion to and from a backrest. The massage machine includes a massage unit (5) that may be raised and lowered in a backrest (2). The massage unit (5) includes a massager (7) projecting toward the front from the backrest (2). A cushion (4) is formed to be generally U-shaped and arranged on a front surface of the backrest (2). The cushion (4) includes an opening (8) in which is arranged the massager (7), which is lowered and raised with the massage unit (5). The massager (7) is movable in the opening (8) of the cushion (4). A fastening means fastens the cushion (4) to the front surface of the backrest (2). The fastening includes hook-and-loop fasteners (10, 11) that are separated by application of downward external force of a certain amount or more to a lower rim of the opening (8) in the cushion (4).

This massage machine comprises a seat 20, a leg-rest 50, a footrest 60, an electric extendable mechanism 80, a link mechanism 70, and a controller. The footrest is movably linked to a lower end of the leg-rest to be movable relative to the leg-rest, and is provided with air bags 63 configured to restrain a foot of the user. The electric extendable mechanism and the link mechanism are configured to move the footrest relative to the leg-rest. The controller gives the user a leg stretching mode, and in the leg stretching mode, the controller controls the electric extendable mechanism and the air bags such that the electric extendable mechanism moves the footrest relative to the leg-rest while the air bags restrains the foot of the user.

An exposure apparatus which forms a pattern on an object. The apparatus includes an exposure head structure in which a plurality of elemental exposure units are arrayed, each elemental exposure unit including (i) at least one light source for emitting exposure light and (ii) an optical element which forms an image of the at least one light source on the object, for exposing the object. Positions of the images of the at least one light source in a direction perpendicular to a surface of the object include plural positions different from each other. A sensor detects a position of the surface of the object and produces a detection result. A controller receives the detection result and controls the exposure head structure such that a pattern is formed on the object by the exposure is selected to expose the object based on the detection result by the sensor.

A chair-type massage machine includes a seat on which a user sits; a leg rest whose one end portion is pivotally connected with a front portion of the seat for pivotal movement up and down, the leg rest supporting calves of the user; a driving unit for pivotally moving the leg rest with respect to the seat; a footrest pivotally connected with the other end portion of the leg rest for pivotal movement up and down, the footrest supporting feet of the user; and a massage means provided to at least one of the leg rest and the footrest. Also, a stopper unit is provided for restricting a pivotal movement range of the footrest with respect to the leg rest, and a biasing unit is disposed for applying a biasing force to the footrest in either an upward or downward a direction of the pivotal movement.
