Ball screw with sectional circulating assemblies

A ball screw with sectional circulating assemblies comprises an inner circulating block and an outer circulating block. In assembly, the inner circulating block is initially placed between the screw shaft and the nut before the rolling balls and the screw shaft are positioned, thus preventing the rolling balls from dropping out and the interference with the threads of the screw shaft. After the rolling balls and the screw shaft are positioned, the outer circulating block is placed into the nut and engaged with the inner circulating block, and the outer circulating block is fixed to the nut. This method can maintain the tightness of the nut, thus preventing the leakage of noise.

Spark plug

ActiveUS20110254428A1High strengthDeterioration of strength is avoidedSparking plugsEngineeringSpark plug
[Objective] To provide a spark plug which is configured such that an insulation member, from which a center electrode projects, is pressed frontward and held in a metallic shell, and is fixed by means of crimping the rear end of the metallic shell, and which can prevent a drop in gas tightness between the metallic shell and the insulation member due to a difference in thermal expansion therebetween.[Means for Solution] In a spark plug in which a mating shaft portion (10) of an insulation member (1) is loose-fitted into a mating hole portion (30) of a metallic shell (21), a filler (41) for maintaining gas tightness is charged between the outer circumferential surface of the mating shaft portion (10) and the inner circumferential surface of the mating hole portion (30). Despite the thermal expansion difference, the gas tightness is maintained, because the filler (41) for maintaining gas tightness is charged between the inner and outer circumferential surfaces.

Easy-pasting exercise patch

An easy-pasting exercise patch includes a patch body having an under surface to which a release paper is attached. The patch body is in the form of a thin sheet having a bottom having a center serving as a reference to define a plurality of turns of non-adhesive-coated circumferential slots in the form of concentric circles. The patch allows ready application by a user to his or her waist or abdomen. After the patch has been pasted, due to the arrangement of the circumferential slots, a radiating stretching force is induced toward the center to force the muscles of the pasted site to do autonomous wriggles for realizing the effect of exercise and removing excessive fat from the pasted site of the human body.
