Title: Axial-flow fan
Inventor: TAKAHASHI KUNIHIRO
IPC: F04D19/00
Filed: 1981-05-13
Abstract: PURPOSE:To improve the efficiency of a fan and to reduce the noise by providing a plurality of static vanes at the delivery side of an impeller while bending in the rotary direction thereby reducing the slewing component of the flow delivered from the impeller. CONSTITUTION:The outer tube is eliminated from the delivery side of the impeller 1 while a plurality of static vanes 3 bent in the rotary direction B are provided radially at the delivery side. The flow from the impeller 1 will slew in the rotary direction B of the impeller 1 and the slew flow is reduced by the static vane 3 thereby the static pressure will increase to improve the efficiency of the fan. Furthermore when bending the static vane 3 in the rotary direction B of the vane 1, the skew effect is produced and the noise due to the collision between the flow from the impeller 1 and the static vane 3 can be suppressed.

Abstract: PURPOSE: To control reactive power over wide ranges, by adjusting a location of a tap of a transformer for a converter by obtaining the maximum allowable value of phase control angles in the case when operating the converter by detecting voltage and currents at the direct current side of an alternating-current and direct-current exchanging device.  
     CONSTITUTION: The output of a constant-current control circuit 8, a constant-voltage control circuit 10 and a constant-allowance angle control circuit 13 is fed to a minimum voltage select circuit 14 to select voltage that gives the minimum phase control angle, and the larger side between the voltage and the output voltage of a function generator 15 is input to an automatic pulse phase shifter 18 by means of diodes 17A, 17B. This device is operated using a phase control angle β as the maximum allowable value. Consequently, reactive power can be changed while the reactive power remains as it is apporoximately kept constant by altering a location of a tap of a transformer 2A for a converter by means of a tap drive circuit 11 when varying reactive power, thus controlling reactive power over wide ranges without enlarging the capacity of valves, etc.

IPC: H04N9/09
Filed: 1979-06-08
Abstract: PURPOSE:To improve the resolution of a solid-state pickup unit with picture elements shifted spatially, by preventing a color shift by performing separation and composition in a fixed method. CONSTITUTION:Once the outputs of two pickup elements arranged with picture elements shifted spatially are supplied to terminals 11 and 16 respectively, a red signal and blue signal appear at the output of amplifier 26 when amplifier 25 outputs a green signal. Therefore, the green signal appears at output 27a of switching unit 27, and the red and blue signals appear at output 27b alternately. The signals of this output 27b are divided into a signal into two; one passes through delay line 28 providing time delay equivalent to one sample period and the other never passes through it and the both are mixed by mixer 29. Next, the output of mixer 29 is sampled by sampling circuits 30 and 31 and separated into the red and blue signals. Thus, the green signal, and red and blue signals can be obtained which cause no vertical shift spatially. Consequently, the resolution can be improved.
