Processes and solutions for phosphating metal surfaces. The solutions are acidic aqueous phosphate solutions containing (a) from 0.1 to 1.5 g/l of zinc ion; (b) from 5 to 50 g/l of phosphate ion; (c) from 0.2 to 4 g/l of manganese ion; (d) at least 0.05 g/l of fluoride ion; (e) less than 0.5 g/l of chloride ion; and (f) a phosphating accelerator. The metal surface phosphated with the solution including galvanized steel, is free of white spots and is suitable for electrocoating.

摘要:
A method for enhancing the corrosion resistance of a metal surface at the edge portion which comprises applying direct current to said metal surface as previously zinc phosphated as a negative electrode in an acidic solution comprising zinc ion in a concentration of 2 to 3 g/L, phosphate ion in a concentration of 8 to 14 g/L and chloride ion in a concentration of 3 to 6 g/L under the condition of 5 to 15 A/dm.sup.2 (metal surface) at a temperature of 20.degree. to 40.degree. C. to make an electric zinc phosphate coating film having corrosion resistance.

The present invention provides a machine tool making it possible that an operator needs to remove a key member from a predetermined position after an unlock condition of a door is established when a door lock mechanism brings the door into an unlocked state, meanwhile the operator can recognize the necessity of reattaching the key member to the predetermined position when the door lock mechanism brings the door into a locked state. In the machine tool, an interlock mechanism 5a allows a door lock mechanism 8 to bring a door 3 into the unlocked state in a state that the unlock condition of the door 3 is established and when the key member 9 is removed from the predetermined position and, after the door 3 is unlocked, allows the door lock mechanism 8 to bring the door 3 into the locked state only when the key member 9 is attached to the predetermined position in a state that the door closed state detection mechanism 7 detects that the door is located at the predetermined closed position.

An endoscopic treatment system 1 of the present invention includes an overtube 2 that is inserted into the body of a patient. An endoscope 7 and a suturing device 8 are inserted into the overtube 2. The overtube 2 has a long and flexible tube main body 3, and a chamber 4 is provided at the distal end of the tube main body 3. The chamber 4 has a lateral hole 10 formed on the lateral surface thereof. The width of the lateral hole 10 is set such that a lesion can be drawn into the lateral hole 10 while preventing other organs on the periphery of the lesion from being drawn into the lateral hole 10.

A ligature device for medical treatment has an operating device that has a ligature tool for medical treatment fitted onto a distal end portion thereof. The operating device is provided with a cutting member that is able to move freely backwards and forwards and is used to cut a ligature wire of the ligature tool for medical treatment. A distal end side of the cutting member has an inclined end portion that is inclined relative to the direction of forward and backward movement, and a blade portion is provided in this inclined end portion.
