摘要:
A biological tissue sheet which is expected as exerting a favorable therapeutic effect and a high safety in transplantation. The biological tissue sheet formed by (a) preparing in vivo-derived cells; (b) sowing the in vivo-derived cells on amniotic membrane; and (c) culturing and proliferating the in vivo-derived cells in the absence of any xenogeneic animal cells. As the cells of a biological origin, for example, cells originating in corneal epithelium, conjunctival epithelium, skin epidermis, hair follicle epithelium, oral mucosa, respiratory tract mucosa, or intestinal tract mucosa.
摘要:
A corneal epithelial sheet having potential for the achievement of a favorable therapeutic effect and being highly safe in transplantation. The corneal epithelial sheet is constructed by: (a) preparing corneal epithelial cells; (b) separately culturing human fibroblasts in a collagen gel; (c) sowing or placing the corneal epithelial cells on the collagen gel; and (d) culturing and proliferating the corneal epithelial cells in the absence of xenogeneic animal cells.

A developing cartridge for developing a latent image formed on a photosensitive member, which is detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a developing member for developing a latent image formed on the electrophotographic photosensitive member with toner; a toner accommodating portion for accommodating the toner to be used by the developing member; first and second light transmitting portions provided in the toner accommodating portion; a first light guide for directing, to the first light transmitting portion, light emitted by a light emission member provided in the main assembly; and a second light guide for directing the light having passed through the second light transmitting portion to a light receiving element provided in the main assembly.
摘要:
The process cartridge has a rotatable member having an electrophotographic photosensitive layer, a cleaning member for removing any residual toner from the electrophotographic photosensitive layer, and a conveying member for conveying the residual toner removed by the cleaning member. The rotatable member and the conveying member each have a drive force receiving portion for directly receiving a drive force from the image forming apparatus.
摘要:
A positioning member has a position, which can be adjusted with respect to a developing container by shifting the positioning member with respect to the developing container, while holding a regulating member by the positioning member.
摘要:
The present invention relates to a developing apparatus which has a developer container, a developer bearing member and a developer sealing member. Also, it is mainly featured that at least a part of the developer sealing member is a conductive portion, and the developer bearing member and the conductive portion have a same potential when a voltage is applied to the developer bearing member.
摘要:
An apparatus for recording and/or reproducing information on or from a tape by drawing out the tape contained in a cassette and bringing the tape into contact with a head, has a chassis and a base which are integrally formed, a slider provided with a member for drawing out the tape, the chassis having a reference surface. The base is provided with a positioning portion for positioning the slider. The positioning portion has a side which is formed in substantially parallel with a virtual line perpendicular to the reference surface of the chassis, or which is inclined away from the virtual line in the direction away from the reference surface of the chassis.
