A keyswitch device includes a supporting seat, a key cap, a circuit board disposed on the supporting seat, and an elastic member located between the key cap and the circuit board. The supporting seat includes a base board and two first confining members that are formed on the base board and that are spaced apart from each other. The key cap includes a cap body and two first hooks that engage respectively the first confining members, thereby inhibiting the key cap to move in horizontal directions with respect to the supporting seat, and allowing the key cap to move vertically in a range equal to the height of the first blocking parts of the first confining members. When the key cap is moved downward, the elastic member deforms to press the circuit board so as to generate a corresponding signal.

A set of profiles for forming complex profiles comprises two profiles, namely a first profile (10) and a second profile (20), adjoining each other and having walls surrounding a main chamber. Each profile (10, 20) of the set has an outer shape which may be inscribed into a triangle, and has an inner wall (12, 22) with a faying face (13, 23) without protruding fragments. The faying faces (13, 23) adjoining each other, after being coated with adhesive enable a joint to be created when the complex profile is discussed, however, in the case of the set of the profiles they are considered to be contact surfaces. After adjoining the first profile (10) and the second profile (20) by attaching the first faying face (13) to the second faying face (23) in order to create a complex profile (30), a first outer surface (15) of first side walls (14) and a second outer surface (25) of second side walls (24) are situated outside of the complex profile and an angle between the first outer surface (15) and the second outer surface (25) equals to a sum of a first angle (α) between the first faying face (13) and the first outer surface (15) of the first side wall (14) of the first profile (10) and a second angle (β) between the second faying face (23) and the second outer surface (25) of the second side wall (24) of the second profile (20).

The invention provides a building block for a mechanical construction. The invention further provides a bearing, an actuator system, a housing, a hub, a mechanical connector and a gear box. The building block includes a first printed material being printed via an additive manufacturing process. The first printed material provides a framework of a second material different from the first printed material and at least partially embedded in the first printed material. The framework of the second material may be included in a hollow structure. Alternatively, at least a part of the framework of the second material may constitute at least a part of the inner wall of the hollow structure. The framework of the second material may be pre-fabricated or may also be generated via the additive manufacturing process. A benefit of this building block is that it allows an increase of strength while limiting the overall weight.

A modified natural rubber particle having carbon-carbon double bonds assigned to multifunctional vinyl monomers graft-copolymerized onto the surface of the modified natural rubber particle, which is prepared by graft-copolymerization of multifunctional vinyl monomers having two or more carbon-carbon double bonds onto natural rubber particles or deproteinized natural rubber particles. One of the methods for producing a modified natural rubber particle includes the steps of: forming inclusion complex of the multifunctional vinyl monomers having two or more carbon-carbon double bonds with a guest-protecting agent to protect at least one of the double bonds of the multifunctional vinyl monomers; graft-copolymerizing the resulting inclusion complex onto natural rubber particles or deproteinized natural rubber particles; and deprotecting the protected double bonds by removing the guest-protecting agent from the obtained graft-copolymer.

The present invention is a fusion-bonded product having a high-strength part, comprising: a first preform (2a) constituted by integrally, frictionally pressure-welding a first low-carbon steel part (L1) made of low-carbon steel containing less than 0.45% of C and a high-carbon steel part (H) made of high-carbon steel containing not less than 0.45% of C; and a second preform (2b) having a second low-carbon steel part (L2) made of second low-carbon steel containing less than 0.45% of C; wherein the high-carbon steel part (H) of the first preform (2a) is provided with a high-strength part (9) that has been previously formed into a desired shape and quenched, the second low-carbon steel part (L2) of the second preform (2b) has been previously formed into a predetermined shape, and the first low-carbon steel part (L1) of the first preform (2a) and the second low-carbon steel part (L2) of the second preform (2b) are bonded to each other by fusion welding.
