Title: Shape memory alloy device
Inventor: HONMA MASARU
IPC: F03G7/06
Filed: 1987-12-19
Abstract: PURPOSE:To protect a shape memory alloy from an overload by making a buckling spring suddenly greatly deformed when a force above a defined magnitude is applied from the shape memory alloy to the buckling spring. CONSTITUTION:When a switch 11 is opened and as a shape memory alloy 8 is at the ambient temperature, the shape memory alloy 8 is in an elongatedly deformed condition from a stored length due to the spring force of a bias spring 9. As the switch 11 is closed, the shape memory alloy 8 is heated by a joule heat and a rotary member is rotated counterclockwise. However, when a load gets larger than a defined value and as a force above a defined value is applied from the shape memory alloy 8 to a buckling spring 2, the buckling spring 2 is buckled and suddenly greatly deformed to relax the shape memory alloy 8, thereby, relieving the shape memory alloy 8 from the load.

Title: Production of electrode material for secondary battery
Inventor: OGURO RYOICHI
IPC: C23F11/00
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve rust-preventing property and to maintain required adhesion even in the presence of an electrolytic solution by performing rust-preventing treatment of the surface of a copper foil by the use of an alkaline chromating bath. SOLUTION: It is preferable to use a chromating bath which is 8-13 in pH and the temp. of which is 15-50 deg.C. It is preferable that rust-preventing treatment is carried out by subjecting a copper foil to be treated to immersion in the chromating bath for 3-30 sec or to cathode electrolytic treatment in the bath. The immersion process enables treatment by means of simplified equipment; on the other hand, the cathode electrolytic treatment can improve the properties of the resultant copper foil to a greater extent thought it requires large-scale equipment. Accordingly, either can be selected according to the degree of desired properties. It is preferable that the thickness of the film formed by the rust- preventing treatment includes (0.005 to 0.032) mg/dm<2> of chromium.  By using the copper foil obtained by the above treatment for an electrode for secondary battery, reduction in discharge capacitance can be prevented even if electric charge and discharge are repeated.

Title: Disc type steam trap
Inventor: ASADA TETSUO
IPC: F16T1/16
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To make a bimetallic ring difficult by a valve disc to be struck.0 SOLUTION: A valve disc 11 is arranged within a pressure transformation chamber 4 formed by inner and outer annular valve seats 6, 7 and a cover member 5. An ended bimetallic ring 13 is arranged on a conical oblique surface part 12 formed on an outer periphery of the outer annular valve seat 7. An annular plate 14 is arranged between the valve disc 11 and the bimetallic ring 13. The valve disc 11 has a cylinder part 15 which is projected downward on the outer periphery and is located at the outside of the outer annular valve seat 7. The cylinder part 15 of the valve disc 11 is larger than the annular plate 14 in inside diameter and is located on an upper side of the annular plate 14.  Steam passing between the outer annular valve seat 7 and the valve disc 11 at high speed and spreading into a pressure transformation chamber 4 flows downward along an inner wall of the cylinder part 15 formed on the valve disc 11 and energizes the annular plate 14 downward. Therefore, the annular plate 14 is hardly sucked upward and so the bimetallic ring 13 is hardly struck by the valve disc 11 via the annular plate 14.
