Abstract: An exposure method includes generating a reticle exposure pattern based on a target pattern, performing a lithography simulation based on the reticle exposure pattern to generate a simulation pattern that simulates a resist pattern formed by reticle exposure, generating differential data between the target pattern and the simulation pattern, generating a first electron-beam exposure pattern based on the differential data, generating a reticle based on the reticle exposure pattern, performing an optical exposure process with respect to a resist by use of the reticle, and performing an electron-beam exposure process with respect to the resist based on the first electron-beam exposure pattern.

Abstract: A horizontal-pulling roll screen door for which the right/left hand can be set or changed easily and safely even by a layman and in a screen door in which a net wound up by a winding shaft of a movable stile is made capable of opening/closing by horizontal pulling. First and second caps rotatably supporting the winding shaft are mounted at the both ends of the movable stile capable of replacement by each other. A lock mechanism which can hold a locked state as necessary is provided between a connecting cylindrical shaft connected to the winding shaft and an intermediate support member connected to the first or the second cap unrotatably and removably. Rotation of the winding shaft by an urging force of a winding spring is prevented by this lock mechanism even when the both caps are removed for assembling or change of the right/left hand.

Abstract: An automatic winding screen device has a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and a damper for alleviating impact and collision noise. Between the damper on a shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed such that, when the winding shaft is rotated in a screen deploying direction, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a screen winding direction the damper is connected to the winding shaft.

Abstract: Even when a damper is provided for absorbing impact and collision noise produced during winding a screen in an automatic winding screen device, the resistance during developing the screen is reduced as small as possible, and in the automatic winding screen device having a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and the damper for alleviating the impact and collision noise, between the damper on a fixed shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed in that when the winding shaft is rotated in a direction developing the screen against the rotational urging force of the coil spring, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a direction winding the screen, the damper is connected to the winding shaft.

Abstract: To assure that each spectator sitting on his seat enjoys a performance in a theater or the like at his desired height, a floor height adjusting mechanism is mounted on each of a plurality of movable platforms constituting a variable floor height telescopic multi-staged spectator seating system. Usually, the floor height adjusting mechanism is constructed in the form of a threaded shaft driving unit which is composed of a motor, a threaded shaft adapted to be rotationally driven by the motor, and a support column fixedly secured to each movable platform. The lowermost end of the support column is operatively connected to the lowermost end of the threaded shaft for rotatably holding the threaded shaft.

Abstract: An apparatus for setting an operative attitude to be assumed by each furniture such as a chair, a table or the like in a furniture accommodating chamber of a furniture raising/lowering type floor equipment is disclosed. The apparatus includes as essential components a raising/lowering unit vertically displaceably accommodated in the furniture accommodating chamber and having an array of furnitures mounted thereon so as to allow the furnitures to assume a raised-up attitude or an accommodated attitude, first and second cam guide rails arranged in the furniture accommodating chamber while standing upright therein so as to assure that the furnitures firmly maintain a raised-up attitude or an accommodated attitude, and a triangular link mechanism operatively associated with the raising/lowering unit and operatively connected to the furnitures so as to enable the furnitures to assume a raised-up attitude or an accommodated attitude.

Abstract: An apparatus for opening and closing covering means for a furniture raising/lowering type floor equipment employable for a building such as a hall, a theater, a gymnasium or the like wherein the covering means in the form of a rigid cover plate is accommodated in a cover plate accommodating gap with the aid of a link mechanism when a plurality of furniture accommodated in a furniture accommodating chamber in an inoperative state are to be raised up to stand upright above the floor surface of the building thereby to assume an operative state is disclosed. The link mechanism comprises an opposing pair of links each having cutouts formed at the opposite ends thereof and an opposing pair of slide links pivotally connected to one end of the cover plate. A flexible cover plate adapted to be laid across the furniture accommodating chamber may be substituted for the solid cover plate.

Abstract: An apparatus for locking an operative position of each furniture such as a chair or the like on a furniture raising/lowering floor equipment wherein the furniture is mounted on a raising/lowering unit vertically displaceably arranged in the furniture accommodating chamber and the operative position of the furniture is reached when the raising/lowering unit is fully raised up and the furniture is then tilted is disclosed. The apparatus includes as essential components a triangular link plate turnably supported on a rotational shaft transversely projecting from the raising/-lowering unit, a support shaft for the furniture turnably arranged on the rotational shaft, an opposing pair of substantially inverted U-shaped turnable engagement pieces, and a pair of joint links bridged between the link plate and the engagement pieces. The raising/lowering unit is provided with engagement projections on the opposite sides at the upper end thereof and a stopper pin at the intermediate position at the lower end thereof.

Abstract: This invention relates to a semi-automatic gas cutting machine which is capable of being operated with one hand freely. More particularly, it relates to a gas cutting machine which enables the steel cutting by: mounting in combination with a controlling apparatus which controls a motor and the rotation thereof, a transmission axis having a first gear at the top and being capable of transmitting the rotation of said motor, a second gear mounted so as to engage with said first gear and rotate around a device head freely, and a driving wheel which is capable of rotation by contacting the outer periphery thereof with said second gear around the device head respectively; and travelling the device head and a cutting nozzle attached to it by the rotation of a driving wheel at the gas cutting.

Abstract: Water-soluble konjac mannan capable of undergoing gelation when heated in an aqueous alkaline solution is obtained by extracting the ground tuber of the konjac plant with water, separating insoluble matter, dialyzing the solids-free liquid against water and then lyophilizing the dialyzed liquid to remove water. This konjac mannan extract has utility for alleviating constipation and reducing weight.
