Title: Al3ti base intermetallc compound and production thereof
Inventor: SUZUKI NOBUAKI
IPC: C22C21/00
Filed: 1993-03-24
Abstract: PURPOSE:To remarkably improve the strength of an intermetallic compound without impairing its lightness by subjecting fine Al3Ti base alloy powder in which a part of Al is substituted by Mo to hot molding. CONSTITUTION:Al3Ti series powder is mixed with, by atom, 0.13 to 3.0 Mo powder, and after that, this mixed powder is uniformly dispersed and refined into alloy powder. This alloy powder is subjected to hot molding and is thereafter subjected to diffusion heat treatment of Mo, at need. By this method, the strength of the lightweight Al3Ti base intermetallic compound can remarkably be improved. Concerning the amt. of Mo to be added, in the case above the upper limit, the embrittlement of the stock is made severe, and in the case of the lower limit or below, the effect to be required can not be expected. Furthermore, uniform alloy powder produced by a rapid solidifying method, a mechanical alloying method or the like is preferably used as a raw material, and, in the case Mo is added by a mechanical alloying method, treatment can be executed without using lube oil owing to the excellent lubricating effect of Mo.

IPC: G01D11/08
Filed: 1988-03-18
Abstract: PURPOSE: To keep a pointer in a stand-still state at the position indicated by the pointer when the pointer is stopped by constituting the pointer so that the rotational torque of a spiral spring developed when a rotating shaft rotates can be offset by the action of an offsetting means.  
     CONSTITUTION: When the first terminal of a pointer driving section 15 is conducted from a power source for vehicle, current and voltage coils 13 and 14 generate the resultant magnetic field corresponding to the remaining amount of fuel in a fuel tank. When the magnetic field is generated, a permanent magnet 11 in a chamber 12 reacts to the magnetic field and rotates together with a rotating shaft 6 and a pointer 3 in accordance with the remaining amount of fuel. The shaft 6 receives a rotational torque generated by first and second spiral springs 16 and 17 in accordance with the rotational angle of the shaft 6. The shaft 6 also receives an offsetting torque generated by a weight 24 in accordance with the rotational angle. Namely, the rotational torque which acts on the shaft 6 is offset by the offsetting torque generated from the offsetting means. Therefore, when the operation of the driving section 15 is stopped by discontinuing the power supply to the first terminal of the section 15, the pointer 3 is kept at the position indicated by the pointer when the operation of the section 15 is stopped.
