Title: Titanium material for electrolytic metal foil producing drum, and its production
Inventor: ISHII MITSUO
IPC: C22F1/18
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a wiring pattern with high precision and high reproducibility as the one for a printed circuit board by allowing it to have a cold-worked structure, to have the area ratio of mechanical twin crystals in the total sheet thickness cross-section in the optional L-cross section a specific value or higher and making the surface of the sheet uniform and dense. SOLUTION: As the cold working, forging, drawing or the like can also be used in addition to rolling. The L cross-section denotes the plane vertical to the sheet face and also parallel to the drawing direction of the structure. The stock is obtd. by executing hot working such as rolling or the like and moreover executing annealing, but, since an ununiform macro-structure is present, mechanical twin crystals are generated by the cold working to obtain a uniform and dense metallic structure. At this time, in the case the area ratio of mechanical twin crystals is >=25% in the total sheet thickness cross-section in the optional L cross-section, at the time of producing electrolytic metal foil by a drum composed of this titanium material, the one free from problems caused by scratches and good as printed wiring can stably be obtd.

Title: Laminate with deoxidation function
Inventor: NOSAKA KEISUKE
IPC: B32B7/02
Filed: 1989-08-17
Abstract: PURPOSE:To enhance deoxidation capacity by dispersing and mixing one or more kind of active metal magnesium, zinc, lead, iron, nickel, tin and manganese between a metal material and an oxygen/water permeable coating layer. CONSTITUTION:Since deoxidation reaction is performed immediately inside an oxygen/water permeable film when a metal forming reaction through the reaction with oxygen is dispersed in an adhesive layer, said metal becomes a barrier against oxygen/water permeability and the effect of an adhesive layer, said metal becomes a barrier against oxygen/water permeability and the effect of an adhesive can be suppressed to the min. and deoxidation capacity can be enhanced. As the metal mixed with this inventive adhesive, magnesium, zinc, iron, nickel, tin and manganese are pref. All of these metals are selected because they are active to oxygen but an alkali metal active to oxygen such as sodium, potassium or calcium is not pref. because said metal is two violent in reaction and generates a large quantity of heat and makes the adhesive strong alkaline after deoxidation reaction to markedly reduce bonding strength.

Abstract: PURPOSE:To make a qualification time shorter and shorter as a speed reduction ratio is higher an higher and to enter next shutter opening operation in a necessary irreducible minimum time at the time of consecutive photographing by providing a control means which varies the qualification time from the stop signal of a winding motor to the qualification of a film stop according to the switching of speed reduction ratio of a winding transmission system. CONSTITUTION:When the camera is set in fast snapshooting mode, a film is wound through a fast transmission system 5 during film winding and when the completion of the winding is detected by a detecting means 8, a control means 2 outputs a motor stop signal to a driving circuit 3, which stops powering on the winding motor M2 and also brakes the motor.
