Title: Highly oxidation-resistant rare earth permanent magnet
Inventor: OTSUKA TSUTOMU
IPC: H01F1/053
Filed: 1988-11-01
Abstract: PURPOSE:To suppress decrease of the magnet characteristic and improve the corrosion resistance by specifying the ratio by volume of an R rich phase to a B rich phase in the metallic magnet texture of an R-T-B alloy magnet. CONSTITUTION:The percentage by volume of an Nd rich phase contained in a sintered body to a B rich phase is made 80% or lower. Formation of local cells by an Nd2Fe14B phase and the Nd rich phase is suppressed by thus making the percentage be volume of the Nd rich phase contained in the sintered body to the B rich phase 80% or lower. Moreover, the corrosion rate of the sintered body can be reduced by making a higher percentage of the B rich phase of a very little difference in electric potential from the Nd2Fe14B phase exist. Passivation of the B rich phase further reduces the corrosion rate, therefore, a highly oxidation-resistant rare earth permanent magnet of improved corrosion resistance can be obtained. If the percentage by volume of the R rich phase to the B rich phase in the sintered body texture is 80% or higher, a large quantity of the local cells are formed by the Nd rich phase and the Nd2Fe14B phase and corrosion proceeds. To further improve the corrosion resistance and obtained a high magnet characteristic, the percentage by volume of the Nd rich phase to the B rich phase must be 20-40%.

Abstract: PROBLEM TO BE SOLVED: To obtain a temperature-compensating function by which a fluctuation of the height of a vehicle caused by an open-air temperature is prevented, in case that a pressure source for adjusting the height of the vehicle of a heat/pressure convertible type is incorporated integrally with a damper. SOLUTION: A case 9, connected with a damper rod 2, is installed outside a damper body 1 with a free motion in the upward or downward direction, and a pressure chamber 10, in which a pressure medium changing reciprocally from a vapor phase to a liquid phase is sealed tightly, is formed between the damper body 1 and the case 9. The pressure medium is vaporized by the heat from a heating chamber 14 where a heated heat medium is run, and thereby the height of a vehicle is raised by the internal pressure of the pressure chamber 10. The circumferential surface of the case 9 is covered with a thermal insulating material 9c, and a cooling fin 9b is formed on a part of the case 9 where the thermal insulating material is not covered.  A cover 16, which covers a forming part of the cooling fin 9b, is installed, and the cover 16 is supported with a support member 17 comprising a coil-spring shaped bimetal, and then the cooling fin 9b is exposed to the outside by raising the cover 16 following the raise of an open-air temperature. The increase of an entering heat amount into the pressure chamber 10, resulting from the raise of an open-air temperature, is compensated by the increase of a radiating heat amount fro the cooling fin 9b, to thereby obtain a temperature compensating function.
