Abstract: PURPOSE:To prevent abnormal deposition of a low resistant semiconductor layer on a gate and improve the selectivity of epitaxial growth by forming an insulating film based on the oxidizing processing of a silicon layer laminated on the gate in a self-alignment manner. CONSTITUTION:After a gate 7 is formed on a semiconductor metal 1 and an insulation layer 5b is formed on the gate 7 in a self-alignment manner, the gate 7 and the insulating layer 5b are used as a mask so as to make a selective epitaxial growth of a low resistant semiconductor layer on an active layer of the semiconductor substrate 1. In this case, an attempt is made to preform a silicon layer 5a (or an aluminum layer) on the gate 7 in a self-alignment manner. Then, the silicon layer 5a (or the aluminum layer) is subjected to oxidizing processing so that the insulating film 5b may be formed thereon. In other words, when an attempt is made to make selectively an epitaxial growth of an n-type semiconductor layer 9 (low resistant semiconductor layer) which constitutes a source and a drain on an n-type semiconductor layer 2, the insulating layer 5b is laminated on the gate 7. This construction makes it possible to prevent definitely the abnormal deposition of the low resistant semiconductor layer on the gate and hence improve the selectivity of the epitaxial growth.

Title: Digital frequency converter
Inventor: RONARUDO DABURIYUU POTSUTAA
IPC: H03K5/00
Filed: 1983-02-01
Abstract: PURPOSE:To realize a high-speed operation of a digital frequency converter with a simple circuit constitution, by performing an exchange between the real and imaginary parts of a digital signal of a complex number type and multiplying by converting the codes. CONSTITUTION:It is possible to express discretely the time by means of a sampling period DELTAt. For instance, a function of a time region is multiplied by exp (-i2pifot), and therefore the frequency spectrum of the function is shifted toward a lower level of frequency. If foDELTAt is set at 1/4 when the time (t) is defined to nDELTAt, the (exp) is equal to the n-power value of + or -i. At this time point, the frequency spectrum has a shift. Then (i)<n> and (-i)<n> are multiplied by an input signal for the up- and down-conversion respectively. The input signal is divided into real and imaginary parts by a circuit 30. The codes of these parts are converted, and at the same time an exchange is given between both parts. As a result, the input signal is substantially multiplied and the frequency is shifted.

A metal pipe body 32 contacts with waste water and is cooled, while functioning as ground electrode. A high voltage from power supply 48 is applied to O 3  generator pipes 34 to cause discharge in annular space between the generator pipes 34 and the pipe body 32. High-pressure air is introduced via pressurizer 44, dehumidifier 58, raw air flow meter 60, and counduit 46 into a hollow base chamber 38, so that ozonized air is provided in a pressure chamber 42. Pressure given to this ozonized air is effective in injecting the air directly into waste water through pores of a distribution plate 56.
