Abstract: A lens drive apparatus includes a base, a lens frame, a nut movable with the lens frame while being threadably engaged with a lead screw, a main guide shaft for guiding the lens frame along an optical axis, an auxiliary guide shaft for guiding the lens frame along the optical axis while inhibiting the lens frame from rotating, and a cover, arranged so as to oppose the base for mating with and securing the main guide shaft and auxiliary guide shaft. The lens frame has a lens holding part projecting out of the base and cover. The base and cover have a first positioning pin and a first positioning hole, which are provided near the main guide shaft, and a second positioning pin and a second positioning hole, which are provided at a position distanced from the main guide shaft. The foregoing can yield a lens drive apparatus having high optical performances, which can be assembled with a high precision.

Abstract: The present invention relates to a composition comprising from about 0.1% to about 10% of a hydrophobic structuring agent; from about 0.1% to about 10% of a hydrophilic surfactant; from about 0.05% to about 8% of a non-crosslinked water-soluble polymer; and water, wherein the composition has a viscosity above about 15,000 cps, and has a highest G? below about 15,000 dyne/cm2 and a highest tan ? above about 0.4 in the angular frequency range of from about 0.1 rad/sec to about 1 rad/sec. The present invention also relates to a cosmetic product comprising a) a composition comprising from about 0.1% to about 10% of a hydrophobic structuring agent, from about 0.1% to about 10% of a hydrophilic surfactant; from about 0.

Abstract: A lens drive apparatus comprises a base 10; a lens frame 40; a nut 70 movable with the lens frame 40 while being threadably engaged with a lead screw 60; a main guide shaft 31 for guiding the lens frame 40 along an optical axis; an auxiliary guide shaft 32 for guiding the lens frame 40 along the optical axis while inhibiting the lens frame 40 from rotating; and a cover 20, arranged so as to oppose the base 10, for mating with and securing the main guide shaft and auxiliary guide shaft. The lens frame 40 has a lens holding part 42 projecting out of the base and cover. The base 10 and cover 20 have a first positioning pin 23a and a first positioning hole 12a which are provided near the main guide shaft 31, and a second positioning pin 23b and a second positioning hole 12b which are provided at a position distanced from the main guide shaft 31. The foregoing can yield a lens drive apparatus having high optical performances, which can be assembled with a high precision.

Abstract: A lens driving unit includes a lead screw, a nut having a projection, and a lens frame having a contact portion that is supported movably in the direction of an optical axis with respect to a base and that is brought into contact with the nut. The nut is held so that only an end face thereof in the direction of the optical axis comes into contact with the lens frame. The base has a guide groove that receives and guides the projection in the direction of the optical axis. The base or the lens frame has a regulatory wall that directs and guides the projection of the nut screwed to the lead screw toward the guide groove only during assembly.

Abstract: The lens driving unit of the present invention includes a lead screw, a nut having a projection, and a lens frame having a contact portion that is supported movably in the direction of an optical axis with respect to a base and that is brought into contact with the nut. The nut is held so that only an end face thereof in the direction of the optical axis comes into contact with the lens frame. The base has a guide groove that receives and guides the projection in the direction of the optical axis. The base or the lens frame has a regulatory wall that directs and guides the projection of the nut screwed to the lead screw toward the guide groove only during assembly. With this structure, vibrations are prevented from being transmitted from the nut to the lens frame, and the nut is securely attached so that the projection of the nut does not deviate from the guide groove.
