Title: Functional air filter
Inventor: KAWAGUCHI EI
IPC: D03D15/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To allow a functional air filter to be hygienic, high in safety and deodorizing property by controlling propagation of a mold and various germs in a good productivity by a method wherein the functional air filter is composed of a knitted textile fabric using a fibrous material spun from a composition wherein a functional ceramic having an antimicrobial property and a deodorizing property is blended in a thermoplastic resin. SOLUTION: As a fibrous material, thermoplastic resins of polyolefin series, polyester series, and or the like are used. For a functional ceramic, silica, alumina, or the like are used as a base burnt product, and metals and metallic salts of silver, zinc, or the like are supported by or blended in these bases, and an antimicrobial operation and a deodorant effect are provided. Though an ordinary monofilament or the like can also be used as the fibrous material to be spun from the thermoplastic resin and the functional ceramic, a honeycomb woven structure is preferable from points of elasticity, flexibility, a ventilating property, a dust collecting property, and a dimensional stability while it is a composite monofilament of a core-sheath type wherein flexibility is maintained and spinning can be highly intensively executed even though a filler is blended. Thereby, an antimicrobial property and a deodorant effect can be expected, and it can be efficiently stably manufactured.

Title: Dust removing cover for portable rotary tool
Inventor: TAKAHASHI MASAYOSHI
IPC: E01C23/09
Filed: 1994-06-02
Abstract: PURPOSE:To suck and recover almost all dust generated by cutting by installing a dust collecting brush in an end part of a cover body communicated with a sucking cylinder body. CONSTITUTION:A peripheral necessary part of a rotary cutter 2b is covered with a cross-sectional almost U-shaped cover body 1a, and a dust collecting brush 3 installed on the cover body 1a contacts with a road surface R, and a partition is formed between the road surface R and the cover body 1a by the dust collecting brush 3. Thereby, suction force generated by actuation of a sucking device can sufficiently act on the road surface R. Thereby, dust S generated when the road surface R is cut by rotating the rotary cutter 2b is sucked in the cover body 1a by being guided by the dust collecting brush 3. Since the dust S sticks to the dust collecting brush 3 and blocks up a clearance between brush hairs of the dust collecting brush 3, an entrance of outside air into the cover body 1a at sucking time is reduced, so that the suction force is further strengthened.

Abstract: PURPOSE:To prevent occurrence of continuity failure between a conductor pattern and a heat generating resistor by forming the heat generating resistor on the conductor pattern wherein a thin film silicone is made on a glaze layer, the conductor pattern is formed thereon, and the thin film silicone is oxygenated. CONSTITUTION:A thin film silicone 6 is formed uniformly on a glaze layer 1 at a process A, a conductor pattern is formed by print patterning at a process B, the silicone 6 is oxygenated by a high temperature processing in an oxidic atmosphere at a process C, and a heat generating resistor 3 and a protective coat 4 are formed by sputtering and patterning at a process D. A silicone oxide film 7 at the process C is a growth of a bare part of the thin film silicone 6 made by the high temperature processing in the oxidic atmosphere after a conductor pattern 2 is formed. Before and after the high temperature processing at the process C, a step difference b' at the surface irregularity changes to a step difference b''. The silicone 6 undergoes a cubical expansion by oxidation so that b'<b is established. Since the step difference b' is effected also on the surface irregularity of the protective coat 4, an adhesive characteristic to a thermosensitive paper 5 will be improved, resulting in improvement of a heat transfer efficiency.

Abstract: PURPOSE: To accelerate filtration and to improve peeling of cake in solar drying of sludge, by laying unfolded porous diaphragm on the whole surface of filter layer prior to the inflow of the sludge.  
     CONSTITUTION: A belt-shaped, reticulated synthetic resin film 6 is unfolded and laid on the filter sand layer 5 at the uppermost filter layer of a solar drying sludge tank 2 from one side to the other side of the circumferential wall. Plural belt-shaped reticulated film 6 are laid in parallel on the whole surface of the filter sand layer 5. Suspending beams 8 having hanging rings 7 on both ends are set up at suitable position on the circumferential hem of the belt-shaped reticulated film 6 so that the beams cross the films in their lateral direction. Sludge is led into the tank 2 and is dehydrated by filtration, and followed by solar evaporation. When a compact sludge layer is formed, the hanging rings 7 are moved a little to form cracks, thereby regenerating the filter effect of the film 6. When the sludge reaches to have a desired moisture content, the top ends of hanging rods 11 of two forklifts 9, 10 are connected to the hanging rings 7 and the cake is peeled by lifting the forks.
