摘要:
The present disclosure provides improved tape dispensers that include a tape roll housing featuring a sidewall and a surrounding, protective wall. At least a portion of the exterior surface of the surrounding wall includes at least one texture. The tape roll housing is coupled to a cutting edge support spaced from the roll housing. The dispensers can include a base defined by portions of the surrounding wall and the cutting edge support. In certain implementations, the based can include a concave portion.
摘要:
In order to use a digital oscillator to generate a target frequency ZT with a "high" or "low" level constant in time from a working clock by variable division by a first division factor, two divider circuits which can be respectively triggered by the positive or the negative edges of a working clock, and to which a control word can be directed alternately by means of a first controlled switch, and which are connected on their output sides to a second controlled switch to obtain a clock pulse. To that end each divider circuit has a logic module which detects the occurrence of the edge of the control word and stores this event, with this event triggering a division by a second division factor.
