    摘要: An image forming apparatus includes an image forming device, a sheet feeder, and a housing. The image forming device forms an image on a recording medium. The sheet feeder stores the recording medium and conveys the recording medium toward the image forming device. The housing accommodates an electrical device in the housing. The housing includes a housing body and a drawer that is drawn out from the housing body. The drawer includes a bottom plate on which the electrical device is placeable and a partition above the bottom plate on which the electrical device is placeable.

    摘要: A lock lever structure includes a shaft; a cam attached to the shaft to fit a different-shaped portion of the shaft to prevent rotation of the cam in a circumferential direction of the shaft, the different-shaped portion having a different shape in cross section from a round portion of the shaft; a lever having an inner hollow cylindrical portion larger than an outline of the shaft and attached to the shaft to be rotatable in the circumferential direction of the shaft; a spring attached to the shaft to press the cam and the lever in an axial direction of the shaft; and a retainer attached to the shaft to retain the spring, the cam, and the lever to the shaft. The cam has at least two valley portions. The lever has a contact portion to contact the cam. The contact portion has a base shape.

    摘要: The reaction of 3',4'-anhydrovinblastine with a Catharanthus roseus-derived protein fraction to form vinblastine is improved by conducting the reaction in the presence of a reducing agent such as the enzyme cofactor NADH. A cationic species such as manganous ion may also be added to the reaction. Vinblastine yields are enhanced.
