    • In an image forming apparatus, a recording head discharges liquid droplets onto a sheet conveyed on a conveying belt to form an image on the sheet. A sheet discharge device is provided downstream from the conveying belt in a sheet conveyance direction and is intermittently driven independently of and in synchronization with the conveying belt to convey the sheet in a sheet discharging direction. A voltage application device applies a voltage to a charger. A distance between the charger and a nip portion formed between a pressing member and the conveying belt for duplex printing is set so that a voltage applied by the voltage application device increases a charged potential of the conveying belt in an area electrostatically attracting a trailing end of a predetermined sheet and a leading end of a subsequent sheet.
    • 在图像形成装置中,记录头将液滴排放到在传送带上传送的片材上,以在片材上形成图像。 片材排出装置在片材输送方向上设置在输送带的下游,并且与输送带独立地且与其同步地间歇地驱动,以将片材沿片材排出方向输送。 电压施加装置向充电器施加电压。 设置充电器和形成在按压构件和用于双面打印的输送带之间的夹持部之间的距离,使得由施加电压装置施加的电压在静电吸引尾部的区域中增加输送带的带电电位 预定片材和后续片材的前端。

    • This invention provides a gas bubble-generating agent that can be used as a contrast medium or a blocking agent in vivo. Such gas bubble-generating agent is produced by a method for producing a gas bubble-generating agent comprising the following steps of: (a) preparing a mixed solution of an amphiphilic substance, an amphiphilic substance comprising a water-soluble polymer chemically bound thereto, a hardly water-soluble substance having a boiling point of lower than 60° C. at atmospheric pressure, and a physiologically acceptable isotonic solution; (b) pressurizing the mixed solution; and (c) centrifuging the mixed solution after the step of pressurization, wherein a molar concentration of the amphiphilic substance in the mixed solution prepared in step (a) is 10 times or more higher than that of the amphiphilic substance comprising a water-soluble polymer chemically bound thereto.
    • 本发明提供了可用作造影剂或封闭剂的气泡产生剂。 这种气泡生成剂是通过气泡发生剂的制造方法制造的,其特征在于,包括以下步骤:(a)制备两亲物质,包含化学键合的水溶性聚合物的两亲物质, 在大气压下沸点低于60℃的几乎不溶于水的物质,以及生理上可接受的等渗溶液; (b)对混合溶液加压; 和(c)在加压步骤之后离心混合溶液,其中在步骤(a)中制备的混合溶液中的两亲物质的摩尔浓度比包含水溶性聚合物的两亲物质的摩尔浓度高10倍或更多 化学结合。
