Title: Manufacture of high corrosion-proof aluminum heat exchanger
Inventor: FUKUI TOSHIYASU
IPC: F28F19/06
Filed: 1980-12-09
Abstract: PURPOSE: To improve the brazing property and corrosion resistance of a heat exchanger in which aluminum structure members are brazed and connected with each  other by a method wherein the surfaces of the aluminum members are galvanized and  a preheating of the members is performed at a specified temperature and for a specified period of time before the brazing temperature is reached.   
     CONSTITUTION: A pipe 1 of 3003 member and fin 2 having their surface layers of Al- 10% Si are assembled to show a corrugated heat exchanger core, a galvanized layer  under a chemical conversion plating process is formed, preheated for more than 5min  and less than 60min at a temperature of more than 350°C and less than 420°C, then a  brazing operation in a furnace with a borite flux is performed for 10min at 605°C.  Forming of galvanized layer weakens an oxidized film for Al member to improve its  brazing property and at the same time the zinc is diffused in the Al member during  its preheating operation to improve corrosion resistance of the product. Under a preheating temperature of less than 350°C, inter-particle diffusion may easily be occurred,  the member is melted at a temperature more than 420°C, resulting in making a non- uniform distribution of zinc to decrease its anti-corrosion characteristic.

Title: Nuclear fuel rod
Inventor: KITA KAORU
IPC: G21C3/18
Filed: 1994-07-25
Abstract: PURPOSE:To provide a nuclear fuel rod which does not generate curving even if usual manufacturing error is allowed. CONSTITUTION:The nuclear fuel rod 10 is provided with a coating pipe 11 both ends of which are closed by end plugs, a large number of cylindrical nuclear fuel pellets 17 which are layered in the coating pipe 11 in the way their end faces are set side by side, and a coil spring 19 put in a gas plenum 21 in the coating pipe 11. The property of the coil spring 19 can be characterized by that the spring force alters proportionally in a small range of sagging and that the spring force alters nonlinearly due to elastic deformation in a large range of sagging. Such nonlinear property due to elastic deformation can be obtained by narrowing the diameter of wire for the coil spring or widening the pitch of the spring as to make the stress at the time of sagging exceed the limit of the elasticity.

Title: Impact resistant door lock automatic releasing mechanism
Inventor: HATAKEYAMA NORIHITO
IPC: E05B77/12
Filed: 1995-06-05
Abstract: PURPOSE: To prevent an occupant from being shut up in a car by arranging high speed unlocking devices in respective doors so as to automatically release a door lock before a door part is deformed by detecting collision by an impact detecting sensor. CONSTITUTION: A sensor to detect impact of collision and wiring to transmit an actuating signal from the sensor to lock devices of respective doors, are provided, and high speed actuation door lock devices to immediately release a door lock by the actuating signal are arranged in the respective doors. When the actuating signal of the sensor detecting impact of collision is received, the door lock devices automatically release the door lock before a door part is deformed since a car is greatly damaged, and prevent an occupant from being shut up in the car. When the actuating signal is made usable in common for an air bag system, an overlap of an impact detecting sensor is avoided. Since an unlocking mechanism is actuated only when an engine moves, unlocking by intentional impact at stopping time and a theft can be prevented.
