Title: Evaluating method for compounded refractory material
Inventor: TAMURA SHINICHI
IPC: G01N3/20
Filed: 1981-11-04
Abstract: PURPOSE:To detect the existence of an inner defect of a processed body of compounded  refractory material, by making a molded sample of the compounded refractory material and measuring hot bending strength in a drying course by heating. CONSTITUTION:A processed body having 100mm. mean thickness is formed on the inner circumference face of an industrial ladle having 3m diameter and 3m height by means of a flask by using compounded refractory material obtained by adding water to compounded refractory materials A, B, C, D and kneading them. Next, the flask is taken off after curing for two hours and said body is dried by raising a temperature up to 1,200 deg.C at 50 deg.C/hr heating speed by using a burner and is cooled spontaneously. Further,  when the processed body is examined by dismantling, stratified cracks are generated in the material A, vertical cracks are generated in the material B and both cracks are generated in the material D. Next, a molded body sample is formed by molding the compounding refractory material by casting in the flask after kneading in the same way and allowing to stand it for three hours at room temperature and then, taking off the flask. These samples are charged in a heating furnace for test and hot bending strength in a drying course is measured. The inner defect is not found in >=30kg/ cm<2> and <=60kg/cm<2> strength range of the hot binding strength by comparing both measured results.

Title: Cladding material for optical glass fiber
Inventor: YOSHIHARA MITSUO
IPC: C09D163/00
Filed: 1983-09-26
Abstract: PURPOSE:To improve workability for removing a clad layer of optical glass fiber without spoiling the adhesivity to the surface of the optical fiber by incorporating a specified amt. of satd. fatty acid into a material for forming a primer clad layer contg. epoxy resin and a curing agent. CONSTITUTION:A material for forming a primer clad layer for optical glass fiber is obtd. by incorporating 0.01-5wt% satd. fatty acid such as lauric acid basing on the total weight of the compsn. including nonvolatile component into an epoxy resin composition consisting primarily of epoxy resin and curing agent such as phenol resin. After forming a primer clad layer with this material, a single or multilayered surface clad layer is formed. When the optical fiber is to be connected, the surface clad layer is peeled and removed leaving the primer clad layer, and the fiber is bonded by fusing. By this treatment, the strength of the connected optical fiber is improved because the primer clad layer is not removed simultaneously with the removal of the surface clad layer.

Title: Water pressure testing method
Inventor: YAMAJI TADAO
IPC: G01M3/28
Filed: 1981-11-05
Abstract: PURPOSE:To judge the pass or fail accurately based on an objective reference, by comparing the pressure value after the water pressure to be tested is maintained for a specified period with an allowable pressure value, in consideration of the pressure reduction due to remaining air quantity, when the pressure is applied in order to attain the water pressure to be tested. CONSTITUTION:The water pressure test of a water pipe in which mortar lining is applied is performed as follows. First of all, air is evacuated and water is injected. Thereafter, the pressure is preliminarily applied in a process (c). This pressure is maintained for 24hr. The pressure is further applied in order to attain the pressure to be tested in a process (e). A pressure value Ph after 24hr is measured, and the value is compared with the allowable pressure value Pk. If Ph>=Pk, the pressure passes the test. If Ph<Pk, the pressure fails in the test. In order to compute the allowable pressure value Pk, at first the quantity of theoretical additional water for pressurization up to the pressure to be tested P is obtained from the pressure value Ph. Said additional water quantity is required because of the absorption of water by the lining, dissolution of remaining air into water and the like. The Pk is obtained by a specified expression from said water quantity and the remaining air quantity. Therefore the pass  or fail can be accurately judged based on the objective reference.
