IPC: E04B5/40
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To attain excellent in-plane shearing yield strength by forming a deck plate with a deck plate main body and a fastening member fixed at least between upper flanges or between lower flanges of the deck plate main body. SOLUTION: A steel pipe is flatly squashed by at least the width of an upper flange 3A at the same interval as the interval between the upper flanges 3A to form a fastening member 4, and the fastening member 4 is fixed between the upper flanges 3A of a deck plate main body 3. The fixing method of the fastening member 4 is determined according to the distribution of the shearing stress applied to the deck plate main body 3. When in-plane shearing stress is applied to the deck plate main body 3 in the direction of an arrow, the fastening member 4 is diagonally fixed so that pressure is applied to the fastening member 4, thereby a deck plate having excellent in-plane shearing yield strength and hardly deformed by the in-plane shearing stress can be obtained.

Title: Numerical controller
Inventor: KOMIYAMA KIYOSHI
IPC: G05B19/18
Filed: 1990-10-23
Abstract: PURPOSE:To detect the abnormality with high precision by applying plural steps of filtering processing to the sampling data on a state signal and comparing simultaneously >=2 pieces of processing data with an allowable range for detection of the cutting abnormality. CONSTITUTION:A comparator means 4 compares simultaneously the arithmetic average values alphai-gammai, i.e., the processing data on the 1st-3rd state filters 21-23 outputted from a filtering processing means 2 with the upper and lower limit levels of each allowable range stored in a storage means 3 respectively. Then the means 4 outputs a signal 9 when the values alphai-gammai are not kept between the allowable ranges H and L like the processing data obtained at a time point T3 shown in a diagram. Thus an operator knows this fact and stops a cutting operation. As a result, the abnormality can be detected with high efficiency even to a sudden peak, the change of a high frequency or a wavy change of a low frequency of a state signal.

Filed: 1988-11-10
Abstract: PURPOSE:To improve capability of extinguishing an arc by blocking the gap between a contact and a nozzle by means of a valve until a fixed arcing contact leaves the insertion through hole of an insulating nozzle, accordingly supplying the heat of an arc to a buffer chamber to increase its inside pressure at the initial stage of a cutoff operation, and decreasing the pressure at the later stage of the cutoff operation, for blowing the gas to the arc. CONSTITUTION:An arc 19 is produced when fixed and movable arcing contacts 4 and 7 are separated, but then the heat of the arc 19 is transferred to a buffer chamber 9 through a discharge path 12 so as to increase the temperature, at the same time, increase the pressure of an insulating gas in the chamber 9. Next, when a driving rod 8 is further shifted in the right direction, the large diameter part 25b of a valve part 25 hits a projection 27a owing to energizing force of a spring 26, and the edge part of the contact 4 and the small diameter part 25a of the valve 25 are extracted, at the same time, from a insertion through hole 11. Accordingly, the pressure near the hole 11 drops suddenly and a high pressure insulating gas in the chamber 9 is blown to the arc 19 for extinguishing the arc. In this way, capability of extinguishing the arc is improved further also the insulation recovery characteristic, after the arc extinguishing, can be improved.

Abstract: PURPOSE:To prevent the occurrence of a crack owing to dry shrinkage by a method wherein a synthetic resin film containing microfoams and inorganic porous substance powder is formed throughout the whole periphery of the side of a glass block. CONSTITUTION:A pair of glass molded products formed in the shape of a box with a bottom and a heat cover are welded at each open end edge integrally to each other to form a glass block 20. A synthetic resin film 10 containing microfoams 11 and inorganic porous substance powder 12 is formed throughout the whole periphery of the side of the block 20. The size of the microfoam 11 is set to 10-500mum, the average grain size of the powder 12 to 10-500mum, and the thickness of the resin film 10 to 100mum or less. When a compression stress generated owing to dry shrinkage of mortar is exerted on a stress absorbing film being the the side of the outer peripheral surface of the stacked block 20, the microfoams 11 and the powder 12, contained in the resin film 10, are deformed or collapsed to absorb a stress. This constitution hardly transmits a stress to the outer surface of a glass block body, relieves a tensile stress exerted on an inner surface, and prevents the occurrence of a crack.
