摘要： PURPOSE:To provide a mechanism capable of releasing a set trigger, employed for a rifle and the like, safely and surely. CONSTITUTION:In order to release the setting of a set trigger, a bolt handle 3 is turned counterclockwise at first from a condition shown by a figure 1. When the bolt handle 3 is turned to a position whereat firing is impossible, an engaging port, formed on the bolt handle 3, is engaged with a release link 21. When the bolt handle 3 is pivoted further, the engaging port 26 retreats the release link 21 downward and a member 22, following the release link 21, pushes a trigger 9 to release the setting of the trigger. The trigger 9 is pivoted into firing direction, however, the holt handle 3 is moved to a position whereat firing is impossible and, therefore, firing will never be effected and the set trigger can be released safely and surely.

摘要： PURPOSE:To obtain a blackening agent for forming a black oxide film having superior corrosion resistance, heat resistance and uniform color density on the surface of a steel material by adding specified substances to NaOH, NaNO3 and NaNO2 as principal components. CONSTITUTION:A blackening agent for forming a black oxide film on the surface of a steel material is obtd. by adding 0.2-0.8% each of 2-mercaptobenzothiazole, 1,2,3-benzothiazole and n-octadecyl chloride to a base having a composition consisting of 67.5% NaOH, 15.5% NaNO3 and 15.5% NaNO2. The blackening agent is dissolved in water to prepare an aqueous soln. having 800-950g/l concn., and the soln. is heated to 115-150 deg.C. A cleaned steel material is immersed in the heated soln. for 20-40min. A homogeneous black oxide film with no irregularity in color can be formed.

摘要： PURPOSE:To prevent deterioration of an immersing soln. and to maintain the effect thereof for a long period of time in the stage of subjecting an article to an immersion treatment with the soln. by forming a fluid film layer which has the specific gravity smaller than the specific gravity of the soln. and is inert to the soln. and the outdoor air on the surface of the soln. CONSTITUTION:A dyeing soln. 5 which is a concd. aq. soln. consisting essentially of NaOH is put into a dyeing tank 1 and a burner 2 is ignited to increase gradually the temp. of the soln. 5. A material for forming a fluid film is put into the soln. 5 to form a film layer 6 when the soln. attains a prescribed temp. A liquid which has the specific gravity smaller than the specific gravity of the soln. 5, floats on the surface of the soln. 5 and is inert to the soln. 5 and the outdoor air, for example, solid paraffin having about 60-70 deg.C m.p. is used for said material for forming the film layer. The thickness of said layer is made about >=15mm.. A material to be dyed put into a cage is immersed into the soln. in this state by which the material is dyed. The deterioration of the soln. 5 is thus prevented and the quality of the material to be dyed is stabilized.

摘要： PROBLEM TO BE SOLVED: To provide a golf club which enables not only expectation for further improvements of performance along with the stability of quality, but also lowering of the production costs with a higher production efficiency. SOLUTION: This golf club is provided with a hitting face formed by joining it with a brazing filler metal on the body 1 of a head. The hitting face mat be formed of a material different in quality from the brazing filler metal as desired or may be formed of the same material as the brazing filler metal, that is, the brazing filler metal itself. Such a golf club has a large coupling strength between the heat body and the hitting face, and further achieves even more excellent ball-hitting performance.
