Title: Method of treating surface of stone material
Inventor: KAWADA AKIO
IPC: B26F3/00
Filed: 1990-01-26
Abstract: PURPOSE:To form recessed and protruded patterns on the surface, and make the finished surface into cracked skin color by splashing the surface of a stone material with liquid spouted from a spouting port at high pressure. CONSTITUTION:The method of treating the surface of a stone material is characterized such that liquid spouted at high pressure from a spouting port is splashed onto the surface of a stone material in order to form recessed and protruded patterns on the surface and, herein, water can be used for liquid that is spouted from the spouting port. In this instance, it is preferable that the spouting pressure of the liquid from the spouting port is to be 1000-3000kgf/cm<2>. Whereby, the color after a recessed and protruded finishment becomes the same cracked skin color as a polished finishment, and such finishment becomes possible even in thin plates.

IPC: H01S5/022
Filed: 1986-01-28
Abstract: PURPOSE:To obtain the function of detecting an output beam intensity with stabilized oscillation wavelength by arranging a beam receiver behind a reflective member arranged oppositely to a rear emission edge plane of a semiconductor laser element and receiving the laser beams emitted backward and reciprocate between the reflection mirror and the semiconductor laser edge plane by reflection at the back of the reflection mirror. CONSTITUTION:When a drive current is injected in a semiconductor laser element 1 to cause laser oscillation, laser beams are emitted forward and backward from an active layer 10 of the semiconductor laser element 1. The forward laser beams are used and the backward laser beams are reflected by a reflective plane 4 of a reflective member 3. After that, the reflected beams feed-backed to a rear edge plane 9 of the laser element are reflected again by this plane to be thrown to the reflective plane 4. The beams going a side from the reflective member 3 are projected to a beam receiver 8 as monitor beams and electric signals are detected, thereby enabling monitoring a laser output beam intensity of the semiconductor laser element 1. Also, those electric signal are feed-backed to a drive circuit of the semiconductor laser element 1 so as to control the drive current of the semiconductor laser element 1. Thus, the output beam of the semiconductor laser element 1 can be controlled at a constant intensity.

Abstract: PURPOSE:To prevent a flow of gas when an overheating is found by a method wherein there are provided a valve and a valve seat which may stop the flow of gas by being contacted to each other and a low melting metal through which gas may freely be flowed is installed between the valve and the valve seat. CONSTITUTION:Safety device for preventing an overheating is stored in the burner 5 in reference to the fact that a temperature of the burner 5 is also increased as a temperature of the curled pipe 6 of in-pipe combustion device is increased.

IPC: B21B23/00
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent shortening of life attributable to chafing of a mandrel bar, thus prolonging the life of the mandrel bar, improve the inner surface quality of a steel pipe, and rationalize the production cost by providing inner peripheral surface edges with the roundness of radius r, assuming that the inner peripheral surface radius is to be d, and satisfying a certain relationship between d and r. SOLUTION: Assuming that the radius of the inner peripheral surface 11a of a stripping die 11 is to be d, the edges 11aa of the inner peripheral surface 11a are provided with the roundness of radius r to satisfy 0.05<=r/d<=0.1. Even when the mandrel bar is brought into contact with the lower position of the inner peripheral surface edge 11aa of the stripping die 11, chafing can be efficiently prevented due to the roundness provided for the inner peripheral surface edge 11aa of the stripping die 11. If the roundness of the edge 11aa is out of the formula range, and if it is applied to a mandrel bar of proper size, chafing is not generated much but the number of strippings per mandrel bar decreases.
