    摘要: An external addition toner that sufficiently exhibits the effect of an external additive and is excellent in transfer property, and an apparatus for forming an image and a process for forming an image excellent in general purpose property that provide an image of good quality without formation of image defects, such as transfer unevenness and drop off due to transfer failure of the toner. An external addition toner is employed, in which the shape coefficient of the toner particles, as well as a coating ratio x (%) of the external additive to a surface area of the toner particles, a volume average particle diameter D (&mgr;m) of the toner particles and a volume average particle diameter d (&mgr;m) of the external additive having the maximum average particle diameter satisfy the prescribed relationship. Furthermore, a developer is employed, which contains a toner charged to a charge amount q (&mgr;C/g) satisfying the following equation corresponding to the volume average particle diameter D (&mgr;m) of the toner particles: q≧929.5/D2

    摘要: A machining control device controls spindle rotational speed. A set of stability limit curve data is stored indicating a relation between a spindle rotational speed and a limit cutting-in amount whereby chatter vibrations are inhibited. Spindle rotational speed and tool cutting-in amount in starting machining are set based on the data. Vibrations of the spindle are detected during cutting. Whether chatter vibrations have occurred is determined based on vibrations detection. Spindle rotational speed is controlled with reference to the data to inhibit chatter vibrations. Cutting-in amount in starting machining is set to be less than a maximum cutting-in amount within a stable region of the data, and spindle rotational speed in starting machining is set to be less than a rotational speed when the cutting-in amount is maximum within the stable region. Spindle rotational speed is increased by an amount of a predetermined rotational speed when chatter vibrations have occurred.

    摘要: In a digital camera, when snapshot shooting is instructed during recording of a moving image, a shot still image is temporarily pushed aside in a memory area for use in pushing aside (7a) in a frame buffer (7). A currently shooting motion image and a still image are displayed in parallel on a display (9), so that a user can confirm a content of a snapshot. The moving image continues to be recorded even during a push-aside operation. After a moving image processing is completed, the still image is processed by an image correcting circuit (4). The frame buffer (7) comprises a plurality of frame recording areas, and is shared on the occasions of a moving image processing and a still image processing. In a normal moving image processing, these areas are utilized in a cyclic manner, and when the still image is shot, any of areas will be utilized. Thereafter, the rest of areas are utilized in the cyclic manner for the moving images. The recording function for the moving image and still image is improved at low cost, it becomes easy to take a snapshot, and the merchandise size is not increased.
