Title: Plastic vortext flow type pump
Inventor: NISHIMURA SHIYUNICHI
IPC: F04D5/00
Filed: 1983-05-18
Abstract: PURPOSE:To form a linear surface in a highly accurate manner as well as to improve pump capacity and reliability, by making an anticorrosion liner contact with the liner surface where a casing and its cover are opposed to an impeller, while embedding the liner inside the casing by means of an ultrasonis weld deposition method. CONSTITUTION:Guiding the inner circumference of an opening part 17 in front of a casing 1, when an ultrasonis vibration of 20Hz or so is added, a linear 10 of the casing 1 being pressed by a vibrating rod 18 is welded in deposition as contacting an end face 20 of a vibrator 18 so that a surface of the linear 10 and perpendicularity at the inner diameter of the front opening part 17 both are accurately finished up. Therefore, parallelism between a liner surface 2A of a casing cover 2 and a surface of the liner 10 becomes highly accurate as a necessity and there pump capacity is kept up in goodness, thus reliability is made ever so better. What is more, a fusion part of a liner surface 1A of the casing 1 also is in a small range so that thermal deformation affecting its size accuracy is as well preventable.

Title: Ghost elimination device
Inventor: KOBAYASHI MICHIO
IPC: H04N5/44
Filed: 1989-04-05
Abstract: PURPOSE:To avoid the deterioration in ghost elimination function due to noise and to reduce the required time of time averaging processing by using a low pass filter circuit to eliminate a noise component with a high frequency included in a tap coefficient group due to the deficiency of the time averaging processing. CONSTITUTION:The time averaging processing through the repetition of the addition with an old latch data in an adder section 13 is implemented for a time less than that of a conventional device. An extracted waveform Fourier transformation section 21 of a ghost detection section 20 applies Fourier transformation to a reference waveform extracted at a pre-stage to generate Fourier coefficient of a quasi-waveform subjected to distortion due to ghost. A low pass filter circuit 24 whose band width is variable in response to a noise level detected by a noise detection section 40 eliminates a high frequency component and the result is fed to an inverse Fourier transformation section 25. Thus, the high frequency component is eliminated in the forming of a tap coefficient group to reduce the time averaging processing number to eliminate the high frequency noise component.
