Title: Production of silica balloon
Inventor: NAKADA TOSHIO
IPC: C01B33/12
Filed: 1989-06-27
Abstract: PURPOSE:To easily obtain high-quality silica balloons whose particle size is regulated in an ultrafine particle range within 0.05-10.0mum outer diameter by atomizing a water glass aq. soln. into the high-temp. combustion gas flow passing through the inside of a closed cylindrical furnace and performing dealkalization and stagnating the produced glass fine particular intermediate in a high temp. furnace for a specified time. CONSTITUTION:High-temp. combustion gas flow is formed by preferably injecting hydrocarbon for fuel such as propane, methane and butane together with the O2-contg. air flow to the top part of a closed cylindrical furnace and completely burning this mixture. A water glass aq. soln. having 20-80wt.% concn. is injected to the inside of the furnace held at the high-temp. level of 1300 deg.C or more. This aq. soln. is quickly and thermally decomposed to perform dealkalization reaction and converted into an intermediate consisting of highpurity siliceous glass fine particles. Successively this intermediate is foamed in a stage wherein it is stagnated in the high-temp. furnace for a specified time. The ultrafine particular silica balloons are formed. Then these silica balloons are cooled by water in the rear step of the furnace and cooled at the temp. not higher than m.p. or below and thereafter sent to a collection stage and recovered.

Title: Corrugated tube for electric wire protection
Inventor: KOBAYASHI KOJI
IPC: H01B7/24
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a corrugated tube for electric wire protection less liable to produce impulse noise and improved in impact resistance and abrasion resistance by making the corrugated tube by using a resin composition of a specific hardness made by mixing/kneading, at a specific ratio, a polypropylene resin with an ethylene-propylene rubber. SOLUTION: An ethylene-propylene rubber of 3 to 30 pts.wt. is mixed and kneaded with a polypropylene resin of 100 pts.wt. to make a resin composition having JIS-A hardness of 80 to 100 Hs. Since the two constituents of the resin composition are excellent in compatibility with each other, physical properties, such as impact resistance and abrasion resistance, of the polypropylene resin are not much lowered. When a corrugated tube for electric with protection is made by the use of this resin composition, a product is obtained excelling in flexibility while maintaining mechanical characteristics. This corrugated tube is less liable to produce big impulsive noise when it makes direct contact with an automobile body or with a wall surface of its through hole, and therefore soft tapes are not required and workability is enhanced.

Abstract: PURPOSE:To improve a discrimination efficiency of tires by setting immediately the reading position and direction of a reading means after a mark position is detected by a position detecting means and therefore decreasing the time during which a reading action is started after the detection is through with the position of a mark train. CONSTITUTION:When a tire 1 is carried by a roller conveyor 2 to a prescribed position of a position detecting station I, a position sensor 8a detects the position of a mark part 10 which is previously magnetized by a beat wire. When the action of an arrival sensor 3 is stopped, a rotary mechanism 8, an up-down shift mechanism 7 and a drive mechanism 6 are reset successively to their original positions. At the same time, the detection signals are delivered to a control means from a tire width sensor 4, an inner diameter sensor and the sensor 8a respectively. Thus the control means controls immediately the drive of a read shift means 17 of a reading station II. Thus an illuminator 15 and a reading means 16 are positioned properly and set in the optimum direction respectively.

Abstract: PURPOSE:To detect a faulty point of a submarine cable very easily, by drawing up a submarine cable in which an AC currnt flows, through the inside in the radial direction of a coil, and detecting a place where induced voltage of the coil becomes maximum. CONSTITUTION:To an end 4 of a submarine cable 3, an AC power supply 5 is connected, and an AC current flows. A towing boat 6 tows a barge 7, and draws up the cable 3 on board from the end of the opposite side of the end 4. In this case, the cable 3 is drawn up through the inside of a split type search coil 9 which has been hung to prescribed depth from the sea surface 1. The AC current flowing through the cable 3 becomes a leakage current 11 from a faulty point 10 and leaks into sea water, but by this current 11, induced voltage is generated in the coil 9. The magnitude of the current 11 is maximum in the adjacent part of the faulty point 10, therefore, when the faulty point 10 passes through in the coil 9, the induced voltage becomes maximum, and accordingly, it is detected by an ammeter connected to the coil 9.

Title: Weight measuring apparatus wherein effect of inner air flow is prevented
Inventor: KITAMOTO KIYOTERU
IPC: G01G21/28
Filed: 1985-07-29
Abstract: PURPOSE:To decrease the effect due to the air flow in an apparatus, in the gap between a pan, on which a material to be measured in mounted, and the inserting part of a connecting body for the pan, by forming and arranging a large cross sectional area part and a small cross sectional area part. CONSTITUTION:The temperature of air is increased by heating of a mechanism part in a main body 10 of an apparatus. The air flows into a casing 6 through a small cross sectional area part 16 of an inserting part of a connecting member 11. At this time, since the heating part is located in the main body 10, the air rises in the main body 10 and tends to stay at the upper part of the main body. Pressure loss is yielded at the small cross sectional area part 16. Therefore, an air bleeder part 17 is formed at the upper part of the main body. Then, a considerable amount of the air flows out of the air bleeder part 17. The air, which has passed the small cross sectional area part 16, reaches an extremely large cross sectional area part 15, where the flow speed is decreased rapidly. Thus the effect on a pan 14 becomes almost zero. When part of the air is made to flow out of the main body 10 furthermore, the absolute amount of the air, which flows into the casing 6, can be considerably reduced.
