摘要:
An inspection apparatus for inspecting an end face of a transparent substrate and an inspection method for inspecting an end face of a transparent substrate according to the present invention are capable of reliably and accurately detecting defects at the end face of the transparent substrate. When a display panel substrate 10 which is a transparent substrate to placed on a rotating table 21, a light is intermittently emitted from an end-face illuminating unit 39 arranged opposite to the end face of the display panel substrate 10. The light emitted along the surface of the substrate 10 is reflected from a lower reflecting mirror 42 toward the end face of the transparent substrate 10. The end face and an adjacent portion thereof are imaged by a CCD camera 36. Defects at the end face of the display panel substrate 10 are detected based on an image density of each pixel in the obtained image data.

A container including a container body configured to hold toner and a mouthpiece configured to deliver toner from the container body. The mouthpiece includes a circular outlet and engagement portions configured as openings located at positions opposed to each other around the circular outlet. The circular outlet is positioned at a center location between the positions of the engagement portions, and the engagement portions are configured to engage with guide members provided at a setting portion on which the container is to be mounted.

A developer replenishing device included in an image forming apparatus of the present invention replenishes a developer from a developer container to a developing device and allows the developer container to decrease in volume when air or the developer is discharged from the developer container. A holder holds the developer container mounted thereto. A regulating device regulates the shape of the developer container when the volume of the developer container decreases.
摘要:
A developer container storing a developer of the present invention includes a developer outlet formed in the side wall thereof, and a shutter member for selectively opening or closing the developer outlet. The shutter member opens the developer outlet when the developer container is mounted to the body of an image forming apparatus or closes it when the former is dismounted from the latter. The toner container with this configuration surely prevents the developer from leaking when the developer container is dismounted from an image forming apparatus.

摘要:
A developer container of the present invention includes a flexible bag whose volume decreases in accordance with the decrease in pressure inside the bag. An outlet forming member forms an outlet for discharging a developer stored in the bag. When the volume of the bag decrease due to the drop of the pressure, a deformation assisting member helps the bag deform to a preselected shape. A developer conveying device and an image forming apparatus practicable with the developer container are also disclosed.
摘要:
An image forming apparatus including a cylindrical image carrier configured to carry an electrostatic latent image while rotating, and a cylindrical developer carrier configured to bear a developer and supply the developer to the image carrier by contacting the image carrier at a nip while rotating, wherein the surface of the image carrier has a friction coefficient of from about 0.1 to about 0.4. The image carrier may be an endless belt.
摘要:
A process for producing calcium D-pantothenate, which comprises bringing a solution containing D-pantothenic acid directly produced by microbial fermentation into contact with activated carbon to adsorb the D-pantothenic acid to the activated carbon, eluting the D-pantothenic acid with a hydrophilic organic solvent, neutralizing the eluate with an alkali agent containing calcium to precipitate calcium D-pantothenate, and collecting the calcium D-pantothenate.
