Apparatus for use in the adhesion measurement of an adhesive sheet comprising a standard surface to be sticked with a main portion of the adhesive sheet, a take-up roller for pulling and taking up the free end portion of the sheet while peeling the sticked sheet portion from the standard surface by the rotation thereof, a source of driving force for rotating the take-up roller, and a torque meter interposed between the source of driving force and the take-up roller for generating torque signals corresponding to the adhesion of the adhesive sheet. The apparatus further includes: a base table extending in parallel with the standard surface; and track rolling members operatively connected to the take-up roller and mounted to a machine frame supporting the take-up roller, the torque meter and the source of driving force, and the rolling members being adapted to roll on the standard surface at the same speed with the peripheral speeed of the take-up roller.

A universally articulable supporting sheath comprises an interconnected series of links, each having a convex spherical surface at one end, and a concave spherical surface at its opposite end. The concave and convex surfaces mate with one another to form the sheath. Special links having branch openings may be provided. Various forms of waterproofing seals are provided, including O-rings, axially compressed rings, flexible belts, and ridges on the spherical surfaces. The links can be fitted together by thermal expansion. However, an axilly split link is also described, which comprises two parts which snap together. The split parts may be molded as a unit with an integral thin wall hinge. The bending characteristics and bending radius of a sheath can be modified by insertion of spacers between the links at selected locations, or by the insertion of pins into radial holes provided in the links. Spacers with tongues may be used to prevent rotation of the links about the sheath axis, while allowing unidirectional articulation. Projections on one of a pair of mating spherical surfaces can be engaged with holes, slots or recesses of rectangular or other shapes to produce various limits on articulation and rotation. A single link may be provided iwth several alternatively usable holes, recesses and the like. The outer surface of a link can be provided iwth an axial extension engageable with a surface of an adjoining link to prevent back bending, or to prevent bending altogether.

A plate spring is operatively connected to an automotive internal combustion engine so that when the engine vibrates with a relatively high frequency and small amplitude, the plate spring is merely moved backwards and forwards across an essentially flat home position wherein it exhibits a zero or even negative spring constant, and so that when the engine vibrates with a relatively low frequency and large amplitude, the spring is flexed to the degree of exhibiting a high spring constant and thus transmits the vibrational energy therethrough to a resilient body or unit interconnecting same with the vehicle chassis.

A multi-piece solid golf ball has a solid core, an envelope layer that encloses the solid core, an intermediate layer that encloses the envelope layer, and a cover that encloses the intermediate layer and has a plurality of dimples on a surface thereof. The diameter of the solid core, the center hardness, surface hardness and hardness difference between the center and surface of the solid core, the thickness and surface hardness of the envelope layer, and the thickness and surface hardness of the intermediate layer are each optimized within specific ranges. Moreover, the intermediate layer is formed so as to be harder than the envelope layer and the cover. In addition, the thickness and surface hardness of the cover, and the combined thickness of the envelope layer, intermediate layer and cover are each optimized within specific ranges.

A component mounting apparatus mounting a component on a substrate includes a driving unit, a frame structure, a first outputting section, and a compensating section. The driving unit includes a head to hold the component and a driving mechanism to move the head. The frame structure is equipped with the driving unit. The first outputting section detects a vibration of the frame structure and outputs first displacement information as displacement information of the frame structure caused by the detected vibration. The compensating section compensates a position of the head that moves by the driving mechanism based on the first displacement information.

A machine abnormality monitoring device has basic information and a priority level preset for each type of abnormality. When an abnormality occurs, snapshot data regarding the abnormality occurrence is stored while being associated with the basic information. In cases where a new abnormality occurs when the snapshot data storage unit has no free storage area, if snapshot data at a priority level lower than that of the new abnormality exists in prior snapshot data stored in the snapshot data storage unit, the storage control unit stores the snapshot data regarding the new abnormality in the snapshot data storage unit in place of the prior snapshot data at the lower priority level while associating the new snapshot data with the basic information. Thus, the administrator is able to acquire the snapshot data regarding an abnormality in question with high reliability.

The invention provides a multi-piece solid golf ball having a solid core, at least one intermediate layer and a cover. The core has a hardness which gradually increases from a core center to a core surface, with the hardness difference in JIS-C hardness units between the core center and the core surface being at least 15 and, letting (I) be the average value for the cross-sectional hardness at a position 15 mm from the core center and the cross-sectional hardness at the core center and letting (II) be the cross-sectional hardness at a position 7.5 mm from the core center, the hardness difference (I)-(II) in JIS-C hardness units being not more than ±2. The intermediate layer has a material hardness and the core has a surface hardness which together satisfy the condition (JIS-C hardness of intermediate layer material)−(JIS-C hardness of core surface)>0. A sphere composed of the core encased by the intermediate layer has an initial velocity and the core has an initial velocity which together satisfy the condition (initial velocity of sphere composed of core encased by intermediate layer)−(initial velocity of core)≧0. The sphere composed of the core encased by the intermediate layer has a deflection and the core has a deflection which together satisfy the condition 0.80≦(deflection of sphere composed of core encased by intermediate layer)/(deflection of core). The cover is formed primarily of polyurethane, and the cover material has a Shore D hardness and the intermediate layer material has a Shore D hardness which together satisfy the condition (Shore D hardness of cover material)−(Shore D hardness of intermediate layer material)≦0. The golf ball of the invention has an excellent flight performance and feel, a good durability to repeated impact, and an excellent scuff resistance.

The first connector includes a first contact having a first contact portion and a first housing configured to hold the first contact. The second connector includes a second contact having a second contact portion that is brought into contact with the first contact portion and a second housing configured to hold the second contact. The connector assembly further includes a positioner operable to position the second contact portion in a first direction so that the second contact portion corresponds to the first contact portion when the second connector is moved relative to the first connector along the first direction. The connector assembly further includes a movement guide operable to guide a relative movement of the second connector relative to the first connector along a second direction perpendicular to the first direction in a state in which the second contact portion has been positioned in the first direction until the second contact portion is brought into contact with the first contact portion.
