Abstract: A biosensor chip is constituted by: a substrate; a metal film which is physically attached to the substrate; and a self assembled monolayer constituted by alkyl chains, which is physically attached to the metal film. Ligands and at least one functional group, selected from a group consisting of a hydroxyl group, a carboxyl group, an alkoxy group, a methyl group, and hydrogen atoms are physically attached to the self assembled monolayer. The ratio between the total number of alkyl chains physically attached to the metal film and the number of alkyl chains which are covalently bonded with the ligands is within a range of 0.40 to 0.99.

Abstract: A carrier comprises a base plate, a polymeric film, which has been bound on a surface of the base plate, and a ligand, which has been bound with the polymeric film. The ligand has been bound with the polymeric film at a density falling within the range of 1.0×1016 pieces/mm3 to 3.3×1018 pieces/mm3. The carrier is produced with a process, comprising the steps of: causing the polymeric film to bind on the base plate, and causing the ligand to bind with the polymeric film, the step of causing the ligand to bind with the polymeric film being performed in an organic solvent.

Abstract: A sheet feeding device includes a feeding unit that feeds a sheet; a rolling member that rolls by having contact with the sheet being fed by the feeding unit; a supporting member that moves along with a behavior of the sheet with supporting the rolling member so that the rolling member rolls in a feeding direction of the sheet at a predetermined position on the sheet; an acceleration measuring unit that measures accelerations acting on the supporting member in three directions; and a detecting unit that detects a feed error of the sheet based on the accelerations measured by the acceleration measuring unit.

Abstract: In the method of manufacturing a superconducting coil, a superconducting line coated with an insulating member is contained in a groove formed on a surface of a stainless steel plate, and a stainless steel lid is fitted in outer side of the superconducting line in an opening in the groove. The lid is formed to fit in the groove. Then, the plate and the lid are welded to seal at joint sections. The welding is conducted using a plurality of heat sources including a laser and an arc so that melting depth at the joint section is within a predetermined range. The lid may have two joint sections, and the welding of the joint sections of the lid may be conducted simultaneously. The plate may have a plurality of grooves, and the welding of the joint sections of the lid may be conducted simultaneously.

Abstract: An amusement device consisting of a manipulative egg-shaped puzzle having top and bottom housings rotatably connected by an internal mechanism. The top housing has a movable slide and a transparent window therein. The internal mechanism comprises a color marking thereon; a shaft fixedly connected to the bottom housing and extending from the bottom housing to the top housing; and a biased lever extending into the shaft for normally holding a movable weight at the top thereof, and an internal housing for supporting a plurality of rotation rings, each of which has a color marking thereon and a lever receptacle therein. When the bottom housing is rotated relative to the top housing the plurality of color markings may be aligned at the transparent window. Properly aligning the color markings necessarily aligns the rings and lever receptacles to allow the lever to move into the lever receptacles and out of the shaft.

Abstract: A toy has a base with a surface thereon. A portion of the surface is movable with respect to the remainder of the surface. A target is mounted on a pedestal above the surface. A self-propelled object is associated with the surface. The object is of the type having a body section and a pedestal section, with a motor located in the body section which is capable of moving the pedestal section with respect to the body section. The object further includes a hand-shaped member which is capable of locking with a post which projects upwardly from the surface of the base near the movable portion of the surface. A moving member is associated with the movable portion of the surface for moving that portion. The moving member is utilized to move the movable portion of the surface such that when the object is located on that portion as the portion moves then the object is also moved.

Abstract: A toy game of skill has a housing and a plurality of members rotatably mounted on the housing such that they are in operative association with one another. One of the members is rotated, and in so rotating that member, the rotation is communicated to the rest of the members to simultaneously rotate them. Located on the members are a plurality of object repositories. A plurality of objects, at least one less than the number of object repositories, are positioned within the object repositories. As the members move with respect to one another, the objects are carried on the object repositories. The objects can be transferred from one repository to an empty repository when two of the members are in a position aligning their respective object repositories with one another. However, the objects are retained in any one object repository whenever the members are in a position with respect to one another such that the object repositories are not aligned.

Abstract: A pinball game is contained within a housing which includes a liquid filled chamber. At least one ball is located within the liquid within the chamber. The ball has a specific gravity heavier than the liquid such that it tends to sink within the liquid but it is light enough to be conveyed upwardly by currents within the liquid. A flipper is located within the chamber and is capable of interacting with the ball to propel it within the confines of the chamber. The flipper is controlled by an actuator member located on the housing and operatively connected to the flipper to move the flipper. At least one goal receptacle is positioned within the chamber and the ball is capable of being located or deposited in the goal receptacle. It is the object to deposit the ball in the goal receptacle by manipulating the ball with the flippers and/or currents of liquid.

Abstract: A game of the type wherein a transparent housing is filled with a liquid and a movable member is located in the liquid can be made competitive by utilizing a first and second circulating member each capable of ejecting a stream of liquid from a nozzle to move the movable member. The game is improved by incorporating within the interior of a housing two separate pivoting members. Each of the pivoting members is located in association with one of the nozzles and moves in response to impingement of liquid ejected from the nozzles. The ejected liquid impinges upon the surface of the pivoting members to both pivot the members and deflect the stream of liquid. The degree of pivoting and the amount of deflection are dependent on the force of ejection of the stream of liquid.

Abstract: A toy game includes a housing having a plurality of target members positioned in a side by side manner near one end of the housing. An attack object can move from a central position in the housing toward the target members and if correctly positioned it can interact with the target members. The attack member is capable of two modes of movement, however, it can only move in one mode at a time. One of the modes of movement is a transverse movement essentially across the width of the target members. The other mode of movement is from a starting point near the central portion of the housing toward one of the objects. If the two movements are coordinated the attack object is capable of interacting with one of the targets. A drive motor moves the attack object in each of the modes of movement via a motion diverting mechanism which is capable of converting motion of the motor into one or the other of the modes of movement at any specific instance of time.

Abstract: Surface-modified cellulose acetate filaments having a microporous structure located in the peripheral surface layer thereof are prepared by bringing non-modified cellulose acetate filaments which have an average degree of acetylation of 50 to 62% into contact with an organic solvent which is capable of dissolving or swelling the non-modified filaments and by rapidly evaporating the solvent from the filaments. The microporous structure causes the surface-modified filaments to exhibit a desirable silklike touch and an increased intensity in dye exhaustion of from 1.1 to 2.0 times that of the non-modified filaments.
