Title: Band dividing and encoding system for packet transmission
Inventor: YOSHIKAWA HIDETAKA
IPC: H04L12/70
Filed: 1989-12-21
Abstract: PURPOSE:To prevent remarkable deterioration of a communication quality even if a packet is rejected by dividing a band signal of each frequency band into at least two groups, forming a packet in every group, and communicating them by different rejection priority. CONSTITUTION:To a band dividing filter 1, for instance, an input signal obtained by converting a sound signal to PCM is inputted successively. When the input signal is inputted successively, the band dividing filter 1 divides each frequency band into a group of a low-pass frequency side and a group of a high-pass frequency side. Subsequently, a low-pass multiplexing part 14 forms a packet of a low pass group, and transmits this packet to a receiving side with higher rejection priority. On the other hand, a high-pass multiplexing part 15 forms a packet of a high-pass group, and transmits it to the receiving side with lower rejection priority.

Abstract: PURPOSE: To remove sludge at a low cost without causing secondary contamination and pollution by branching one end of a transport pipe, opening one end onto the bottom of a lake or a marsh, opening the other end at a place lower than the bottom of the lake or the marsh and connecting the transport pipe to a solid-liquid separator. CONSTITUTION: A straight pipe and a bend consisting of a raw material resisting abrasion and water pressure are connected in an airtight manner by flanges, thus forming a piping 16. The main pipe 34 of the piping 16 is branched into a plurality of branch pipes 36 and placed along the bottom of a lake or a marsh, and opening sections 18 are formed to each end section. Suction tools 38 and cut-off valves 22 controlling a water flow or interrupting the water flow when the operation of a removing device 10 is stopped are installed to the opening sections 18. On the other hand, an opening section 24 at another end of the piping 16 is formed at a place lower than the opening sections 18 on the bottom of the lake and the marsh, and sludge is sucked by the water flow by a fall and discharged into the opening section 24.  When a part of the intermediate section of the piping 16 is upper than a water surface, a pump 28 is mounted on its midway of the piping 16 and water is pumped up, and discharged by the fall. The opening section 24 is connected to a solid-liquid separator 14, sludge and water are separated, and only clean water is discharged.
