Title: Communication controller
Inventor: KINOSHITA JUNHEI
IPC: G06F13/00
Filed: 1990-11-29
Abstract: PURPOSE:To eliminate the need to input commands by operator's intervention by recognizing a dial signal received from a modem and a DTR signal sent to the modem and automatically inputting a line startup command when the command needs to be inputted. CONSTITUTION:The DTR signal is at 'L' when a line is disconnected.

Title: Filtration device for gas purification
Inventor: NISHIWAKI AKIJI
IPC: B01D47/00
Filed: 1990-11-30
Abstract: PURPOSE:To eliminate the necessity to remove a filter and clean or replace it frequently by recover a filter cleaning liquid supplied to a filter gradually, then circulating the liquid using a pump to be supplied to the top of the filter continuously and allowing the liquid to run along the surface of an air-diffusible part of the filter constantly so as to drop the liquid. CONSTITUTION:A cleaning liquid in a tank 7 is allowed to leak out of small holes 9 on the top side part 2a of a filter 1 continuously by uniformly appropriate amount, using a pump 5, and runs down to the lower side part of the filter. In this case, the cleaning liquid flows down along the surface of an air-diffusible part of a mesh material 3 for the filter 1. Subsequently, dust in the gas captured by the filter 1 is washed downward to the lower part of the filter 1 together with the cleaning liquid immediately. Thus, the filter is no longer contaminated by accumulating pollutants. Further, the cleaning liquid running down on the surface of the air-diffusible part of the filter 1 is capable of capturing the pollutants of a contaminated gas. Subsequently, the large-scale detachment of the filter need not be performed, although the cleaning liquid itself becomes fouled due to its use and has to be replaced.

Title: Burying machine for linear body
Inventor: YAMADA NORIO
IPC: E02F5/10
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce resistance force unrelated to burying of a cable, reduce required burying machine tractive force, and easily secure a desired burying depth. SOLUTION: A burying machine 10 has both side sleds 1 and the intermediate excavator 2. First water injection nozzles 11 are arranged on the bottom surface of the sleds 1, and second water injection nozzles 12 are arranged on a front face of the sleds 1. When burying a submarine cable by towing the burying machine 10 by a towing wire 4, since the second water injection nozzles 12 of the front face of the sleds 1 remove earth and sand 6 of the front face, earth removing resistance force F2 reduces. The first water injection nozzles 11 of the bottom surface of the sleds 1 reduces frictional resistance force F4 between the sleds and the bottom of the sea. Then, since the resitance forces F2, E4 unrelated to burying of the cable reduces, burying machine tractive force F1 reduces. Thus, the desired cable burying depth can be easily secured.
