Title: Heavy duty pneumatic radial tire
Inventor: HOSHINO EIZO
IPC: B60C9/08
Filed: 1990-11-28
Abstract: PURPOSE:To increase durability of a carcass construction, the folded ends of which are extended to a belt layer area, by providing cushion rubbers which are reduced in thickness gradually from their thick wall parts, provided near the edges of a belt layer, toward a bead portion and the equatorial surface of a tire are arranged between the edge of the belt layer and the folded ends of the carcass. CONSTITUTION:A carcass 2 is provided with folded portions 9 which are curled from the inside of a tire in the axial direction to the outside around a bead wire 1, and the folded ends 8 of which are further extended to the underside area of a belt layer 4. In this case, cushion rubbers 10 which are reduced in thickness gradually from their thick wall parts 10a, provided near the edges of the belt layer 4, toward a bead portion 3 and the equatorial surface 0 of a tire are arranged between the folded end 8 and the belt layer 4. Then the thickness of the thick wall part 10a of the cushion rubbers 10 is set to a thickness equivalent to 15 to 40% of the tread thickness L at the equatorial surface 0 of the tire. Thus pulling-in of the folded end 8 caused in vulcanizing process is avoided to obtain high durability especially useful for tires forced to be run under heavy duty condition.

Title: Gas indicator
Inventor: HAMAGUCHI MASAAKI
IPC: G01N31/00
Filed: 1989-12-12
Abstract: PURPOSE:To stepwise detect gas with the elapse of time to display the same by supporting an indicator or a liquid mixture of the indicator and reactive chemicals on an adsorbent. CONSTITUTION:As the base material of a gas display device, paper, a nonwoven fabric, transparent plastic, a glass plate or a film are used. For example, a vinyl acetate emulsion is applied to the entire surface of the nonwoven fabric and an activated clay powder is scattered thereon and, after drying, non-bonded activated clay is removed. A 1/3 area of the coated nonwoven fabric is covered with a film and the remaining 2/3 area is again coated with the vinyl acetate emulsion and activated clay is scattered on the entire surface of the nonwoven fabric to perform treatment in the same way as the previous time. Next, the 2/3 area of the whole is covered and the remaining 1/3 area is treated in the same way to prepare an activated clay coated nonwoven fabric having a three- layer structure. The nonwoven fabric is immersed in a pH indicator methyl red solution prepared beforehand for 0.5hr and dried to obtain the gas display device. Gas can be stepwise displayed with the elapse of time using this gas display device.

IPC: B21B25/06
Filed: 1993-12-22
Abstract: PURPOSE:To obtain a mandrel bar which is excellent in resistance to thrust load and withstands use for long time by pivotaly supporting the tip of the mandrel bar and plug mounting part with a double-row test bearing. CONSTITUTION:By incorporating an annular material whose cross, section is made into an L-shape from a face with which thrust load is received into either of an outer cylinder 3 and rotary shaft 6, the thrust bearing 5 is imparted with the function equivalent to two rows of the thrust bearings 5a, 5b are loaded on the same surface. Thrust load added to the thrust bearings on two places is dispersed, falls on two pairs of bearing rollers 13a, 13b and the load loaded on either one of the bearing rollers is reduced. Consequently the life of the thrust bearing 5 is remarkably prolonged without executing size change such as the enlargement of external size and it is dissolved that breakage of the thrust bearing 5 is a bottleneck. In this way, by prolonging the life of the plug mounting part, the centrifugal whirling state of the mandrel bar is eliminated, the deterioration of peripheral equipment is reduced and productivity is improved.

Title: Regenerating device of cation exchange resin and regenerating method
Inventor: TSUKITA YUUJI
IPC: C02F1/46
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent a cation exchange resin for forming a weakly acidic soft water from being deteriorated during regeneration with gaseous chlorine and hypochlorite in an acidic water for regeneration. SOLUTION: When a city water is electrolyzed, an acidic water is formed at an anodic side chamber and an alkaline water is formed at a cathodic side chamber, especially, when an electrolytes (Na<+> and Cl<-> ) are supplied to the cathodic side chamber, the Cl<-> is permeated through a diaphragm and allowed to enter the anodic side chamber to be bonded with H<+> to form HCl, and a strongly acidic water is discharged from the anode side. This strongly acidic water is brought into contact with the cation exchange resin and the cation exchange resin in regenerated. On the other hand, the gaseous chlorine and the hypochlorite are incorporated in the strongly acidic water, but they are removed by a method such as adsorption to active carbon and hardly contacted with the cation exchange resin.

Filed: 1990-11-26
Abstract: PURPOSE:To attain high cache access speed by comparing tag addresses outputted respectively from 1st and 2nd tag memory means, outputting a hit signal when the result of comparison indicates coincidence and outputting an error signal when the result of comparison indicates dissidence. CONSTITUTION:When an address is outputted from a CPU 10, a same tag address is outputted from 1st and 2nd tag memories 11a, 11b.

IPC: H04M3/56
Filed: 1993-12-22
Abstract: PURPOSE:To eliminate the need of performing a manual operation such as the turning OFF of a microphone, etc., at random by detecting the howling and performing a retraining. CONSTITUTION:This canceler is provided with each of grouped echo cancelers 3-1 to 3-n. When the coupling state of a microphone and a speaker changes by the movement of persons in a conference room, howling is generated.
