IPC: H01H50/20
Filed: 1984-09-25
Abstract: PURPOSE:To enhance the magnetic efficiency of the title solenoid, to accomplish a low power consuming operation and a high speed operation, and to contrive reduction in the cost of manufacture by a method wherein magnetic attraction force is utilized effectively. CONSTITUTION:When a coil 15 is demagnetized in the state wherein the amount of displacement of a plunger 12 reached maximum, the plunger 12 returns to is original position by the force of a return spring 18. The end face of a mag netic flux receiving part (outer circumferential drum) 22 comes in contact with the bottom part 20b of a positioning member 20 through the intermediary of a buffer material 29, and it returns to a stop position. In this hammer solenoid 11, as the attracting part 23 of the plunger 12 and the end face 13a of a fixed core 13 are facing each other on the same axis, the receiving area of the mag netic flux can be made larger and magnetic efficiency is enhanced, thereby enabling to obtain high magnetic attraction force with low electric power con sumption. Also, as the positioning member 20 has the same shape as a guide frame 19, the metal mold for exclusive use for molding is unnecessary, and the control of parts is made easier, thereby enabling to contribute toward reduc tion in cost.

Filed: 1986-09-01
Abstract: PURPOSE:To measure an interatomic distance and an atomic distribution state with high accuracy, by continuously scanning a substance by X-ray energy from the vicinity of the absorption end of the arbitrary element in the substance to a high energy side. CONSTITUTION:X-rays from an X-ray source 1 are allowed to be incident to a specimen 4 through a detector 2 and the intensity of X-rays is detected by a detector 3. Said detector 3 is arranged in large numbers at a minute interval and the incident angle theta of X-rays is continuously changed between 0-90 deg.. The absorptivity of X-rays is measured in such a state that energy lower than the proper absorption end of an aiming element is set to a start point. Further, the energy of X-rays is allowed to continuously scan from the absorption end to a high energy side. At this time, an X-rays absorption spectrum mu is calculated from the X-ray intensity ratio of the detectors 2, 3 before and after X-rays are incident and EXAFS (Extended X-ray Absorption Fine Structure) is calculated from said spectrum. Since EXAFS is calculated, the distribution state of the element, the interatomic distance thereof and number of coordinations in a substance can be measured quantitatively.

Title: Production of chromium nitride
Inventor: NAKAMURA YOSHIYUKI
IPC: C01B21/06
Filed: 1984-09-29
Abstract: PURPOSE:To produce a high-purity chromium nitride free from metallic chromium, using metallic chromium powder as the raw material, by controlling the rate of temperature increase in a specific temperature range. CONSTITUTION:Metallic chromium powder having particle diameter of <=150mum (preferably electrolytic chromium powder) is nitrided by heating in a non- oxidizing atmosphere containing nitrogen or ammonia. In the above process, the temperature is raised to 1,000 deg.C while keeping the rate of temperature increase in 800-1,000 deg.C to <=10 deg.C/hr, and then heated to a high temperature (preferably about <=1,400 deg.C). When the particle diameter of the metallic chromium powder exceeds 150mum, high-purity product cannot be produced because the metallic chromium powder is left in the CrN produced in the first stage of the reaction and is transferred to the product.

Filed: 1986-08-29
Abstract: PURPOSE:To restrict an abrupt change in steering wheel holding force at the time of a quick start accompanied by steering in the captioned device of a front-drive-vehicle, by controlling the damping force of a shock absorber for a predetermined period of time in accordance with the steering direction, when a quick starting state is detected and when the steering angle exceeds the predetermined value. CONSTITUTION:A vehicle speed signal, engine revolving speed signal, and a gear shifting state signal, which are detected by a vehicle speed detecting means M2, an engine revolving speed detecting means M3, and a gear shifting state detecting means M4, respectively, are input into a quick start detecting means M6. When both vehicle speed and engine revolving speed are higher than the predetermined speed and moreover when the gear shifting state permits a quick start, a quick start signal is output to a damping force changing means M7. If the steering angle that is input from the steering state detecting means M5 is greater than the predetermined value when the quick start detected signal is input, a damping force changing means M7 changes the damping force of the damping absorber MI for a predetermined period of time in accordance with the steering direction, thereby restricting the rolling. With this constitution, an abrupt change in steering wheel holding force at the time of a quick start can be restricted.
