  • FOCUS CONTROL DEVICE FOR BEAM PROJECTOR
    Publication number: 20100265475
    Abstract: A focus control device for a beam projector allows the focus of a lens assembly to be finely and easily controlled. The focus control device includes: a control member rotatably mounted on the beam projector for controlling the focus of a lens assembly; a rotary eccentric member provided in the control member, the rotary eccentric member having a control axis eccentric to the rotary axis of the control member, and being rotated while depicting an elliptical trace in response to the rotation of the control member; a focus guide member provided in the rotary eccentric member, the focus guide member allowing the lens assembly to be moved rectilinearly in the direction of an optical axis in response to the rotation of the control member; and an actuating member provided in the lens assembly and coupled to the focus guide member, the actuating member moving the lens assembly in the direction of the optical axis in response to the movement of the focus guide member.

  • Method for stimulating hair follicle cell proliferation
    Patent number: 7335641
    Abstract: The present invention relates to novel hair follicle growth factor (HFGF) proteins, genes encoding HFGFs, methods for preparing HFGF proteins and therapeutic uses of HFGF proteins. The HFGF proteins of the present invention have a characteristic reduced expression in hair follicles derived from alopecia patients and have a stimulatory effect on hair follicle cell proliferation. HFGF proteins may be used to prevent or treat alopecia and to promote or accelerate hair growth and hair follicle repair.
