    摘要: A delay circuit externally adjustable for the delay time "n" as desired, which comprises a FIFO (FIRST-IN, FIRST-OUT) type memory, a self-load counter, and a decoder circuit. In addition to a data signal, an input clock is inputted to the memory as the write clock and the read clock. The self-load counter operates in synchronization with the input clock, and loads a setting of a load value-designating signal at a prescribed number of counts. The decoder circuit receives the output of the self-load counter which has a prescribed cycle, and outputs a reset signal with the same cycle to the memory. This cycle determines the delay time. The delay circuit allows a greatly reduced number of ICs used as compared with the prior art, even for increased delay times.

    摘要: A control apparatus for an inverter including a filter consisting of a reactor and a capacitor, connected to the output terminal thereof is operative to compute such a voltage correction value to cancel a voltage difference between the reference voltage and the output voltage to add, to the voltage correction value, a value obtained by delaying the voltage correction value by one period of the inverter output voltage to prepare a reference correction value to correct the reference voltage by the reference correction value, thus to prepare a volatge command for control of the inverter. The voltage control based on the reference correction value is carried out in a feed-forward manner, thus making it possible to effectively eliminate voltage distortion appearing periodically in synchronization with the output voltage.

    摘要: A masterslice semiconductor device has two kinds of basic cells including a first one having the same size same as that of ordinary basic cells in a prior art masterslice semiconductor device and a second one having a size larger than that of the first basic cell. A number of the large-sized basic cells are arranged along columns of a semiconductor substrate and constitute a plurality of basic cell arrays which are disposed along rows of the semiconductor substrate. Each of the basic cell arrays of the second basic cells is situated between two adjacent basic cell arrays of the first basic cells. Each of the regions occupied by the basic arrays of the second basic cells can be used for distributing interconnecting lines as in the prior art masterslice semiconductor device. At least one of the second basic cells in each of the regions serves to interconnect the first basic cells in adjacent basic cell arrays, and also provides an elementary circuit block, that is a unit cell, in conjunction with the first basic cells.
