Title: Telephone device and method for encoding and decoding voice
Inventor: KOMIYA KOZO
IPC: H04B1/3822
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To remove a delay obstructing voice signal by permitting an interframe boundary of input voice frames to he earlier than the inter-frame boundary of output voice frames for the portion of a processing time which is required for an echo cancel processing and a decoding processing. SOLUTION: A voice decoder 6 considers the processing time portion of the echo cancel processing and a voice decoding processing, decodes voice packet data S2 so as to permit the boundary of the output voice frame to be after 3ms being a longest time which is required for the echo cancel processing and the decoding processing as against the boundary of the input voice frame(voice sample data S7) which is written in an input buffer 13 and writes it in an output buffer 18 as voice data S11. Thus, a state where the output voice frame at the same time as that of the input voice frame to be written in the input buffer 13 is normally written in the output buffer 18 is kept. Therefore, the delay obstructing voice signal is removed from the input voice frame based on the output voice frame and voice with high quality is outputted.

Title: Dust collector
Inventor: UEDA YOSHIZOU
IPC: B04C5/30
Filed: 1978-09-25
Abstract: PURPOSE: To contrive the improvement of the dust collection efficiency for the raw material  powder for manufacturing the cement, by arranging the inner cylinder provided with both ends of  cone type concentrically in the wind tunnel, by radially installing the plural inclined blades in the  ring type passage between the wind tunnel and the inner cylinder, and besides, by setting two  exhaust ducts to the wind tunnel in the stepped type so as to make the diameter of the rear stage  to be smaller.  
     CONSTITUTION: The waste gas including the raw material powder for manufacturing the cement  at high concentration is introduced into the wind tunnel 1 by the fan 12 installed in the duct  system. The waste gas flows along the inner wall surface of the wind tunnel 1 outside of the inner  cylinder 2 provided with conical frint end and is guided by the inclined blades 3. Next, the waste  gas makes a whirling current which forces the dust included in the waste gas so as to move toward the inner wall of the wind tunnel 1 separately from the flow of gas depending on the centrifugal  force; hereby, the fluid current including further concentrated dust is formed along the inner wall  surface of the wind tunnel 1, and the greater part of the dust is primarily separated at the ring  type passage 6 in the former stage, and then, the residual fine dust is secondarily separated at the  ring type passage 7 in the rear stage. The cleaned waste gas is exhausted from the exhaust duct  5, and thus separated dust is introduced into the cyclone 10 through the pipes 8, 9, and is separated from accompanying waste gas.
