Inventor: NUKUI KAZUMITSU
IPC: F16K31/06
Filed: 1995-04-26
Abstract: PURPOSE: To surely shut off a gas passage by a simple structure when fires occur. CONSTITUTION: An inner shaft 23 having a thermal expansion rate much larger than that of a valve shaft 15 is incorporated in the valve shaft 15. When the inner shaft 23 in the valve shaft 15 is expanded and extended due to heat generated when fires occur, the valve shaft 15 attracted on a yoke 21 by a permanent magnet 22 is moved away from the yoke 21. When the attraction force of the permanent magnet 22 against the valve shaft 15 declined below the restoring force of a compression coil spring 19, the valve shaft 15 is quickly pushed toward a valve seat 13 by the compression coil spring 19 and a valve body 14 is moved. Then, the valve body 14 is brought into contact with the valve seat 13, thereby closing the valve fully.  A normal valve closing operation is performed by instantaneously supplying a current to an exciting coil 18 and exciting the valve shaft 15 in a direction reverse to the permanent magnet 22.

Abstract: PURPOSE:To reduce the welding cost by using mixed gaseous Ar for the welding of a first layer, switching it automatically to gaseous CO2 for the welding of a second layer and thereafter, and executing built-up welding, while reproducing the position data of a welding torch at the time of a first layer. CONSTITUTION:By using a robot 10 having a rocking inversion type arc sensor function, first of all, the first layer of a member 30 to be welded is brought to automatic welding-all-around, while shielding it by mixed gas mainly composed of Ar. Since mixed gaseous Ar is used, the control of an arc sensor at the time of welding of the first layer can be executed stably. Subsequently, at the time of the welding a second layer, the gas is switched to gaseous CO2, and welding is executed, while reproducing the position data of a welding torch 1 is the first layer. A third layer through a final layer are brought to automatic welding-all-around similarly under the atmosphere of gaseous CO2. In such a manner, since inexpensive gaseous CO2 is used, the running cost of the welding can be reduced.

Title: Splash cover installing construction
Inventor: OOHATA YOUICHI
IPC: B62D25/16
Filed: 1982-07-22
Abstract: PURPOSE:To securely instal a splash cover and prevent it from suffering damage by molding the areas of contact of the splash cover body and its mounting pieces, and those of the legs of said mounting pieces and the mounting areas in thin- walled bendable forms. CONSTITUTION:Since a splash cover A is firmly fixed to side members 35 and to a front cross member 33, it does not hang down due to its own weight or vibration. On the other hand, the cover A is installed to a suspension member 37 through bendable mounting pieces 23. Accordingly, even if the suspension member 37 swings back and forth or up and down while the car is running, the splash cover A never breaks since the vibration is absorbed due to the relative movement between mounting areas 19 and mounting legs 27, and between the splash cover body 1 and the mounting pieces 23.

Filed: 1982-07-20
Abstract: PURPOSE:To give low friction coefft. and superior durability, by using a magnetic coating film contg. as binder components a specified polyurethane resin and a vinyl chloride copolymer in a specified proportion, and polyisocyanate in addition. CONSTITUTION:The binder components of the magnetic coating film contains a polyurethane resin having <=170kg/cm<2> 100% modulus, and a vinyl chloride copolymer in 95:5-70:30 ratio, and in addition, 20-80pts. polyisocyanate for accelerating cross-linking reaction per 100pts. binder. The use of such binder components enhances strength of the coating film greatly, and gives superior durability. When polyisocyanate is added by <=20pts., mechanical strength of the coating film is lowered, and when by >=80pts., it becomes brittle, and both cases are not preferable.
