Title: Particulate trap device
Inventor: NIIMURA KEIICHI
IPC: F01N3/023
Filed: 1993-06-11
Abstract: PURPOSE:To reduce the power consumption of an electrical heater by blowing the high pressure air from an air reservoir to a filter having particulates arrested from exhaust on the preset timing, and controlling the electrical heater to be turned on over the preset period on that timing. CONSTITUTION:A flow passage in a trap body 10 has two systems, and filters 11 and 12 are laid in the systems. Also, downstream flow passages 13 and 14 are fitted with shutter valves 15 and 16. The valves 15 and 16 close the passages 13 and 14, upon receipt of the air from an air reservoir 19 due to the opening of solenoid valves 17 and 18, while opening the passages 13 and 14, upon the interruption of the air due to the closure of the valves 17 and 18. At the time of backwashing the filter 11, the shutter valve 15 is closed and the solenoid valve 24 is opened, thereby feeding the high pressure air to a backwash nozzle 22 and blowing down arrested particulates to a combustion chamber 20. In this case, the solenoid valve 24 is actuated to open and close over the preset short period. Also, an electrical heater 21 is turned on over the preset time, when engine speed becomes higher than the preset value. According to this construction, particulates can be quickly burnt and removed, and power consumption can be reduced.

Title: Coal and tar mixed fuel for blowing into blast furnace
Inventor: MIYAZAKI TOMIO
IPC: C21B5/00
Filed: 1979-10-31
Abstract: PURPOSE:To stably produce molten iron of less sulfur contents under a low fuel ratio and high working efficiency by using a slurrylike fuel made by mixing pulverized coal and desulfurizer into coal tar in place of a heavy oil to be blown together with hot blast from tuyeres during blast furnace operation. CONSTITUTION:A slurry fuel mixed with pulverized coal, desulfurizer and coal tar is blown together with hot blast through tuyeres at the blast furnace operation. The pulverized coal of <=5mm. sizes is mixed at about <=65% as the concn. in the slurry, and the desulfurizer such as CaO, Na2CO3, CaCO3 or MgO is added at <=50wt% so as to become <=65wt% in the total of the mixing ratio with the pulverized coal. Since inexpensive coal tar and pulverized coal are used as raw materials without the need for heavy oil, the stable operation may be performed at a low cost. In addition, the desulfurizer is added and therefore the S content of the molten iron produced is low and the out-of-furnace desulfurization operations are decreased.

Title: Plastic container
Inventor: KAI HISAO
IPC: B29L22/00
Filed: 1987-06-08
Abstract: PURPOSE:To improve contacting characteristics between a plastic container and its wrapping film by specifying the surface roughness of the plastic con tainer having a smooth surface surrounding the outer periphery thereof. CONSTITUTION:A plastic container has a smooth surface surrounding its outer periphery. When measured in accordance with the requirements of JIS B0601 with respect to the surface roughness of a smooth surface, the maximum height for the standard length 0.25mm is specified to be not more than 0.35mum and the relative load length not more than 10% per cut level 30%. In the case of the standard height exceeding 0.35mum the desirable improvements of adhesive ness with the plastic container and the wrapping film are not recognizable. It is important that the surface load length be small in terms of percentage based on a low t.p. value. This means that no ridges projecting from a cross-sec tional curve exist and the adhesiveness with the wrapping film and the plastic container are improved. In order to produce a smooth surface having the afore said surface roughness, the outer periphery of a container is polished to a width of about 1-3cm by, for example, using an abrasive material of the average particle size in the order of 1mu or a metal die finished to a mirror surface may be used in the injection molding or stamping.
