Title: Volute fan
Inventor: TANIGUCHI SEIICHI
IPC: F04D23/00
Filed: 1980-06-10
Abstract: PURPOSE: To enhance the efficiency of a volute fan, by shaping the lower portions of plural radial blades of an impeller so that the lower portions extend oppositely to the direction of revolution.  
     CONSTITUTION: An impeller 13 with a plurality of blades 14 is secured on a drive shaft 4 by a nut 15. The lower portion 20 of each blade 14 is bent in the direction of revolution 19 to reduce an impact loss which is caused when a swirl flows onto the blade 14. When the impeller 13 is rotating in the direction 19, air in an air passage flows into the impeller 13 at a relative speed in the direction 21 to become a swirl shown by an arrow 22 in the drawing. Since the lower portion 20 of each blade 14 is bent in the direction of revolution 19 so that the inflow angle of the air to the impeller 13 is equal to the reception angle of the blade 14, the collision loss on the lower portion 20 is reduced. Therefore, the efficiency is improved.

Title: Trimming method of frequency regulating pattern of oscillator
Inventor: NAKAJIMA KAZUHIKO
IPC: H01F21/04
Filed: 1984-04-20
Abstract: PURPOSE:To make it possible to regulate quickly, coarse and fine an oscillating frequency, by constituting a frequency regulating pattern with strip conductors having a plural of alternate routes and by cutting them at given positions of the frequency regulating pattern. CONSTITUTION:A frequency regulating pattern which consists of a coarse regulating pattern 2 and a fine regulating pattern 4 is constituted with strip conductors. The coarse trimming is done by cutting in zigzag (x1, x2...), causing the pattern to make long and fine. The fine trimming is done so as to cause the pattern to make fine (y1, y2...). The frequency regulating pattern has a different trimming value of inductance according to the difference of the cutting position. Therefore, by changing the size of the space areas 3, 5 or the width of the pattern, trimming of about 10MHz per one cutting can be attained with the coarse regulation and trimming of 2MHz with the fine regulation, and required regulation and fine regulation are attained easily.

Abstract: PURPOSE: To make confidential the video information sent, by transmitting the video signal for a part of scanning lines through inversion to the time axis and by receiving it with the receiver for exclusive use.  
     CONSTITUTION: In transmitting the video information formed with a plurality of scanning lines 7, 7'..., for example, the sequence of the video elements of the video signal is transmitted by inverting it every scanning line. In this case, if the video signal is received with normal unit, the position of the black video elements 8, 8'... is recorded with inversion every video line and the picture obtained is meaningless. But, by adding the selector switch 10 inverting the scanning direction of the multi-needle recording head 2 to a receiver every scanning line, normal picture can be obtained from the video signal fed with inversion to establish confidentiality to other receivers. By arbitrarily setting the scanning direction of scanning lines for the inversion, exclusive confidentiality can be achieved.

Filed: 1984-04-21
Abstract: PURPOSE:To produce an oxygen-enriched gas from air with small energy consumption and high efficiency, by operating a process by a specific pressure variable adsorption method using three adsorption columns filled with a selective nitrogen gas adsorbent in combination. CONSTITUTION:(i) Air is fed from an end for a raw material of an adsorption column (A) under reduced pressure condition thereto, and an oxygen-enriched gas from an adsorption column (C) is fed from a product end thereof [the oxygen-enriched gas of the adsorption column (C) is partially taken out of the apparatus] to equalize the pressure of the adsorption columns (A) with (C). On the other hand, the pressure of the adsorption column (B) is reduced to desorb nitrogen. (ii) Nitrogen in the adsorption column (B) is purged while feeding the oxygen- enriched gas from the adsorption column (C) to the product end of the adsorption column (B) to make the interior of the adsorption column (B) under reduced pressure conditions. On the other hand, the oxygen-enriched gas is taken out of the adsorption column (A) to the outside of the apparatus. The combination of the above-mentioned adsorption columns is changed over from (A-C-B) to (B-A-C) [i.e. the role of the adsorption column (A) is transferred to the adsorption column (B), and the role of the adsorption column (C) is transferred to the adsorption column (A). The role of the adsorption column (B) is transferred to the adsorption column (C)]. The operation is then performed cyclically by the combination of (C-B-A) and (A-C-B).
