    摘要: The circuit configuration for the generation of clock signals for a semiconductor memory (14) that are edge-synchronous with the output signals of a clock generator (16) comprises an input stage (20) to which the output signals of the clock generator (16) are applied. It furthermore contains a phase detector (30) which receives the signals output by the input stage (20) and whose output signals control a voltage-controlled oscillator (34) which supplies the clock signals for the semiconductor memory (14). It also contains a conversion stage (42) which applies signals related to the output signals of the oscillator (34) to the phase detector (30), which controls the oscillator in such a way that the phase difference between the signals reaching it from the input stage (20) and the signals also reaching it from the conversion stage (42) becomes zero. The input stage (20) comprises an amplifier (44) containing a circuit component (62) capable of influencing the signal transit time. This circuit component (62) is controlled in such a way as to change the signal transit time in inverse proportion to the changes of the output signals of the clock generator (16).

    摘要: In a carillon or chimes keyboard, which may be a manual or a pedal set, theeys (sticks or pedals) and the frame for taking them up pivotally are provided with cooperating surfaces, one surface on the key hitting the other surface on the frame at the end of the upward release movement of the key after it has been depressed for operating a bell.For dampening the clattering noise caused by this hitting, the invention provides for such cooperating surfaces on the keys and the frame, which are inclined, preferably at about 30.degree., to the upward direction of movement of the keys just before they hit on the frame during this release movement.

    摘要: Voltage regulator with an output transistor MP1, including a first PMOS FET, whereby the input voltage Vdd of the voltage regulator is applied to the source of the output transistor MP1 and where the drain of the output transistor MP1 constitutes the output of the voltage regulator. The voltage regulator, furthermore, includes a regulation circuit 1 that may, for example, consist of an error amplifier and that controls the output transistor in such a way that the least possible deviations between the output voltage Vout and the target output voltage are allowed to occur. The voltage regulator includes a switch-on protection circuit that includes a second PMOS FET MP2, whereby the source of the second PMOS FET MP2 is connected to the input voltage Vdd of the voltage regulator, the drain of the second PMOS FET MP2, by way of a pulldown resistor R3, to a reference potential Vss, and the gate of the second PMOS FET MP2 to the reference potential Vss, and which furthermore includes a third PMOS FET MP3, where the source of the third PMOS FET MP3 is connected to the input voltage Vdd of the voltage regulator, the drain of the third PMOS FET MP3 is connected to the gate of the output transistor MP1, and the gate of the third PMOS FET MP3 is connected to the drain of the second PMOS FET MP2.
