Title: Al3ti dispersion strengthened aluminum alloy, its powder, and their production
Inventor: SUZUKI NOBUAKI
IPC: B22F1/00
Filed: 1993-12-27
Abstract: PURPOSE:To produce an Al3Ti dispersion stregnthened aluminum alloy powder by mixing specific percentages of Al3Ti powder with pure aluminum powder, subjecting the resulting powder mixture to mechanical alloying treatment, and uniformly dispersing Al3Ti. CONSTITUTION:Pure Al powder (about 250-20mu grain size and <= about 99% purity) is used as a matrix, and Al3Ti powder (<= about 150-250 mesh) is mixed with it so that mixing ratio becomes 5-45wt.% based on the whole. Further, instead of pure Al powder, an Al alloy powder containing <= about 7wt.%, in total, of at least two elements among Cu, Ni, Mg, Si, Zn, Fe, etc., can be used. Then, the resulting powder mixture is put into a high energy type ball mill and subjected to mechanical alloying treatment. At this time, in view of powder dispersion and lubricating effect, alcohol can be added so that the amount of carbon mixing in from the residue of alcohol becomes <=1wt.%. By this method, the highly heat resistant aluminum alloy, in which Al3Ti is uniformly dispersed, can be obtained.

Title: Vehicle height adjustment system
Inventor: SHONO SHOICHI
IPC: B60G17/015
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce frequency of switching over an actuator and the chance of noise generation and improve durability by inhibiting determination of the start of the vehicle height adjustment when the detected physical quantity such as acceleration is larger than a first predetermined value, and by interrupting changing of the vehicle height when the detected value is larger than a second predetermined value. SOLUTION: This system is provided with hydraulic cylinders 11a to 11d constituting an actuator for setting the vehicle height. A microcomputer 30 calculates an acceleration of a vehicle in its longitudinal direction based on the vehicle speed detected by a vehicle speed sensor 33. If the acceleration is larger than the first predetermined value, determination of starting the vehicle height adjustment is inhibited. Otherwise, if the second predetermined value is set to be substantially large so as to reduce frequency of interrupting and resuming the vehicle height adjustment, the frequency of the vehicle height adjustment owing to the vehicle height change caused by the change in the acceleration in the longitudinal direction.  As a result, the frequency of switching over the actuator and accordingly, the chance of the abnormal noise generation can be lowered, thus improving durability.

Title: Air damper assembly
Inventor: SUTEIIBUN ERU BIIBENSU
IPC: F16F9/02
Filed: 1995-12-27
Abstract: PURPOSE: To eliminate the influence of foreign matter by providing a piston head with a lip seal and orifice, and constituting in such a way that the lip seal is engaged with the inner peripheral side wall of a housing at the time of a piston rod moving outward and released at the time of the piston rod moving in the opposite direction. CONSTITUTION: In a closing position, a piston rod 14 is fixed into a housing 12 by a latch 22. When the rod 14 is slightly pressed to the left, the latch 22 is released, and the rod 14 is pushed out of the housing member 12 by a coil spring 18 so as to move into an opening position. At this time, a lip seal 16 is engaged with the inner peripheral side wall of the housing 12 excluding an orifice 46 so as to eliminate air flow. The rod 14 therefore slides at a braked speed ratio. When the rod 14 is pressed to the left, the latch 22 seizes the rod 14 into the housing 12. At this time, the seal 16 is not engaged with the circumferential side wall of the housing 12, so that the air in a head chamber 34 is discharged to a rod chamber 36 so as to close at a high speed ratio not braked. The blocking of air flow caused by foreign matter in external environment can thereby be prevented.
