Abstract: PURPOSE:To produce rare earth element-based permanent magnet powder having improved corrosion resistance by mixing rare earth element-based magnet powder, that is, RE-Fe-B alloy powder with metallic zinc particles and subjecting the mixture to electroless zinc plating with a plating soln. contg. zinc sulfate and sodium hypophosphite. CONSTITUTION:Rare earth element-based magnet powder, that is, RE-Fe-B alloy powder (RE is at least one kind of rare earth element including Y and <=20% of Fe may be substd. by Co) is mechanically mixed with particles, sandy grains or powder of metallic zinc preferably in 10:1-1:10 volume ratio. This powdery mixture is immersed in an electroless zinc plating soln. contg. zinc sulfate and sodium hypophosphite to form a zinc film on the magnet powder. The pref. concn. of zinc sulfate in the plating soln. is 0.02-5mol/l and that of sodium hypophosphite is 0.02-5mol/l. The corrosion resistance of the rare earth element-based permanent magnet powder is easily improved at a low cost without deteriorating the magnetic characteristics.

Title: Multiple access system
Inventor: SAKATA HIRONOBU
Filed: 1988-03-23
Abstract: PURPOSE:To eliminate a free token wait time in inter-node communication by storing a communication busy token tentatively when the communication busy token between other nodes is inputted from an upper stream transmission line while a busy token from its own node is being sent to a lower stream transmission line. CONSTITUTION:A node in nodes 11-1n sends a busy token sent from its own node immediately to the down stream of a transmission line 21-2n when a busy token for other inter-node communication is not passed therethrough. When a busy token for the communication between other nodes is inputted from the upper stream of the transmission line 21-2n while the nodes 11-1n send a busy token, the busy token is stored and the busy token stored at the end of transmission of the busy token from its own node is sent to the down stream of the transmission line 21-2n. Thus, even if the nude number is increased, the transmission line is prolonged and there is a delay in the node of free token, the retarded wait time is prevented.

IPC: E01C7/35
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To perform construction work in a short time, and restrain scattering of an aggregate by laying/leveling a mixture of a normal temperature execution work type using a quickly hardening modified asphalt emulsion and the aggregate as an essential component on a road surface, and scattering/compacting a chip material before hardening the mixture. SOLUTION: A mixture of a normal temperature construction work type using a quickly hardening modified asphalt emulsion and an aggregate as an essential component is laid/leveled on a road surface. Afterwards, a chip material is scattered/compacted before hardening the mixture. The layer is quickly stabilized according to removal of moisture in the emulsion, and time up to finishing decomposition of the emulsion is shortened by about 1 to 2 hours. Since the aggregate (a chip material) is stably fixed, there is practically no danger of damging a windshield of a traveling vehicle since the aggregate (the chip material) scatters at vehicle traveling time.

Filed: 1989-03-20
Abstract: PURPOSE:To shorten the time for measurement by writing a test signal which is linearly increased in frequency in one round of the tracks of a magnetic disk and correcting the crest values of the envelope signal of the reading-out signal thereof by a modulation correcting factor. CONSTITUTION:The writing current which is linearly increased in the frequency is outputted from a frequency sweep generator 5 by the command of microprocessor 2 and the test signal is written in one round of the tracks. The crest values to the respective rotating angles of the envelope signal detected by an envelope detector 7 are similarly transferred to the processor 2 and are multiplied by a modulation factor, by which the data of the normal envelope signal to the respective rotating angles is obtd. Since the relations between the rotating angles and the frequencies are previously known in the processor 2, the frequency D50 which has the amplitude of half the low frequency is determined from this detector and is outputted to an output section 2b.

Filed: 1993-02-17
Abstract: PURPOSE:To eliminate the influence by fluctuation in atmospheric state by inserting a fixed medium in the light path of heterodyne interference optical system and detecting the fluctuation in refractive index on the basis of a difference in length measurement result. CONSTITUTION:Light of a two-frequency laser 10 is separated into a first two-frequency laser light 1 and a second two-frequency light 2 by a beam divider 15 and a reflection mirror 16. The first and the second laser light, passing through separate light paths enters a deflection beam divider 11. Then, the light having mutually different deflection orientations and frequencies are divided and directed respectively to a fixed corner mirror 13 and a movable corner mirror 12. The reflected lights are joined together at the divider 11, then by passing through deflectors 17, 18 of orientation 45 deg., are mutually superimposed, and thus enter detectors 11, 22, so that light beat is detected. A transparent body 14 (a fixed medium) of thickness 'a' and refractive index No are inserted in a second light path. And thus, the difference in light path between an interferometer made in the first light path and an interferometer made in the second light path and the variations are obtained, so that the refractive index of the environment and its variation are obtained.
