    • Shifter circuits comprise a matched translation stack comprising at least first and second stacks each of which comprising multiple transistors. The matched translation stack is configured to provide a primary logic level shift between a voltage level away from which a shift is desired (VddL) and a voltage level to which the shift is desired (VddH). One or more high voltage buffer stages are provided, at least one of which being connected with and biased by the matched translation stack. At least one high voltage buffer stage comprises multiple transistors arranged in a transistor stack that is biased by the first stack of the matched translation stack, and is connected to receive an input supplied by the second stack of the matched translation stack. The high voltage buffer stage also comprises an inverter that drives an output stage which is also driven by a low voltage buffer stage.

    • A shifter circuit comprises a high and low voltage buffer stages and an output buffer stage. The high voltage buffer stage comprises multiple transistors arranged in a transistor stack having a plurality of intermediate nodes connecting individual transistors along the stack. The transistor stack is connected between a voltage level being shifted to and an input voltage. An inverter of this stage comprises multiple inputs and an output. Inverter inputs are connected to a respective intermediate node of the transistor stack. The low voltage buffer stage has an input connected to the input voltage and an output, and is operably connected to the high voltage buffer stage. The low voltage buffer stage is connected between a voltage level being shifted away from and a lower voltage. The output buffer stage is driven by the outputs of the high voltage buffer stage inverter and the low voltage buffer stage.
    • 移位电路包括高低电压缓冲级和输出缓冲级。 高电压缓冲级包括布置在晶体管堆叠中的多个晶体管,其具有沿堆叠连接各个晶体管的多个中间节点。 晶体管堆叠被连接在被移位的电压电平和输入电压之间。 该级的逆变器包括多个输入和一个输出。 逆变器输入端连接到晶体管堆叠的相应中间节点。 低电压缓冲级具有连接到输入电压和输出的输入,并且可操作地连接到高电压缓冲级。 低电压缓冲级连接在远离电压和较低电压的电压电平之间。 输出缓冲级由高压缓冲级反相器和低电压缓冲级的输出驱动。

    • A description is given of a mold for manufacturing concrete moldings, e.g. paving setts, large-volume blocks and large-format, thin panels, having a bottom mold part which comprises the mold chamber(s) and having a top mold part with a load plate and the die or the dies. The bottom die parts (47) which come into contact with the concrete in each case are guided so as to be movable in the vertical direction, with respect to the top mold part, in a displacement range defined by stops (46, 51, 53) and are exposed to the action of a pressure medium, e.g. a bellows (40) activated by compressed air. The manufacturing process claimed works with two successive fillings. After the first filling pre-compaction is carried out at a relatively high pressure, and after the second filling secondary compaction is carried out at reduced pressure, the reduced pressure resulting in desired striking of the movable die part against the other die in the same rhythm as the vibrations.
    • 给出了用于制造混凝土模制品的模具的描述,例如。 铺路板,大体积块和大型薄板,具有底模部分,该底模部分包括模腔,并具有带有负载板和模具或模具的顶模部分。 在每种情况下与混凝土接触的底部模具部件47被引导为在垂直方向上相对于顶部模具部件在由止挡件(46,51,53 )并暴露于压力介质的作用下,例如 由压缩空气激活的波纹管(40)。 所要求的制造工艺与两个连续填料一起使用。 在第一次填充之后,在相对较高的压力下进行预压实,并且在第二次填充之后,在减压下进行二次压实,减压导致可动模具部件以相同的节奏相对于另一模具的打击 作为振动。

    • Concrete-molding machine having a ram on which an upper mold part is fastened in a releasable manner. The quick-fastening device used for this purpose comprises connecting pins which have a shank and a widened cross-piece. In order to simplify the device, the connecting pins are fastened on the upper mold part by means of their shanks. Located on the ram or on a carrying plate fixedly connected thereto is a horizontal slide with keyhole-like clearances into which the connecting pins can be inserted from beneath. Pneumatic lifting elements grip below the slide and draw it up, in the connecting position, to the cross-pieces.
