  • Patent number: 11918531
    Abstract: Provided is a thermotherapy device, which includes a first housing (10), a second housing (20) disposed under the first housing (10), a transfer plate (30), at both sides of which transfer rollers (31) are provided, and a pair of guide rails (40) that is provided to the second housing (20) and on which the respective transfer rollers (31) of the transfer plate (30) are placed. The pair of guide rails (40) are integrally molded when the second housing (20) is injection-molded. Thus, since the guide rails on which the transfer rollers of the transfer plate travel are integrally molded when the second housing is injection-molded, inefficiency caused by mounting separate rails as in the related art is removed, and thereby assemblability, productivity, and economic efficiency of the thermotherapy device can be improved.

  • Patent number: 9354573
    Abstract: A fusing device and an image forming apparatus having the same are provided. The fusing device includes a position regulating device to regulate a position of a side frame which rotatably supports a fusing belt, thereby fixing a position of a fusing nip defined between the fusing belt, inside of which a heat source is placed, and a pressure roller arranged to face the fusing belt. The fusing device prevents shift of a recording medium delivery path due to deformation of the pressure roller.

  • Patent number: 8831495
    Abstract: A fusing device to reduce lubricant leakage, includes a fusing belt having a heat source placed therein, a pressure roller placed to apply pressure to an outer surface of the fusing belt, and a nip plate to support an inner surface of the fusing belt so as to define a fusing nip between the fusing belt and the pressure roller. The nip plate includes a stepped portion spaced apart from the inner surface of the fusing belt so as to define a space for accommodation of a lubricant applied to the inner surface of the fusing belt. The fusing device may further include a side frame to rotatably support a longitudinal end of the fusing belt. The side frame may be provided with a lubricant guide to guide the lubricant on the longitudinal end of the fusing belt toward the center of the fusing belt.

  • Patent number: 8562675
    Abstract: In one aspect, the present invention provides an ophthalmic lens (e.g., an IOL) that includes an optic having an anterior surface and a posterior surface disposed about an optical axis. At least one of the surfaces (e.g., the anterior surface) has a profile characterized by superposition of a base profile and an auxiliary profile. The auxiliary profile can include an inner region, an outer region and a transition region between the inner and the outer regions, where an optical path difference across the transition region (i.e., the optical path difference between the inner and the outer radial boundaries of the transition region) corresponds to a non-integer fraction (e.g., ½) of a design wavelength (e.g., a wavelength of about 550 nm).

  • Patent number: 8320796
    Abstract: Disclosed herein is an image forming apparatus including a main body; a developing unit detachably mounted on the main body and having a photoconductive medium; and a cover pivotably mounted on the main body to cover and support an outer end of the developing unit. The cover may comprises a latch engaged with the main body by one end thereof so that the cover supports the developing unit. A member that supports a shaft of the photoconductive medium may also be included. Because the member operates in association with the latch, opening and closing of the cover may be facilitated, accordingly also facilitating separation of the developing unit from the main body.
