    摘要: A semiconductor device comprises a semiconductor substrate formed with at least one well containing impurity ions of either a first conductivity type or a second conductivity type; a plurality of transistors each having a gate insulation film formed on the well, a gate electrode formed on the gate insulation film and a pair of diffusion layers formed in the well; and an outer diffusion layer of the same conductivity type as that of the well and self-aligned with each of the diffusion layers in an outer periphery thereof within the well; the outer diffusion layer having an impurity concentration sufficient to provide a desired junction withstand voltage and having substantially the same width as that of a depletion layer to be generated when an operational voltage is applied to the corresponding transistor; the impurity of the well being set for a concentration such that a threshold voltage of a parasitic transistor appearing below the gate electrode connecting adjacent transistors is higher than a power supply voltage, whereby the adjacent transistors are isolated from each other.

    摘要: An image forming apparatus includes an image processor, an exterior housing, a fixing unit, an outlet, and a first partition. The image processor is configured to transfer a toner image to a recording medium. The exterior housing accommodates the image processor. The fixing unit is configured to fix the toner image, transferred by the image processor to the recording medium, onto the recording medium. The outlet is on the exterior housing and communicates with a conveyance path extending from the image processor toward the fixing unit. The first partition is adjacent the outlet on the exterior housing. The first partition separates the image processor and the fixing unit from one another.

    摘要: An image formation apparatus has a waste toner accommodation unit including a toner transporting rotation member covered with a fixed pipe. As the member rotates, waste toner in the pipe is transported downstream A fin involved in detecting an amount of toner moves upward and downward with a predetermined amplitude as the member rotates. The pipe has a projection secured by an elastic member to a bottom of the waste toner accommodation unit, and when waste toner reaches the level of the pipe, the waste toner is compressed in the pipe downstream and thus increases in density, and together with the waste toner the pipe starts to rotate. As a result, the projection rotates to a position allowing it to interfere with the fin, and the fin decreases in amplitude. Such variation in amplitude is detected by a sensor and a state full of toner is thus detected.
