Title: Flat lid for container for very high degree of vacuum
Inventor: ITOU KOUJI
IPC: F16J13/02
Filed: 1982-09-29
Abstract: PURPOSE:To avoid a large deformation due to pressure or load and prevent bolts from yielding, by providing a grooved portion inside the portion of a flat lid, which is brought into contact with a metal gasket and by making the section modulus of the grooved portion smaller than that of the portion clamped by the bolts. CONSTITUTION:The section modulus of bolts 5 is made larger than that of a grooved portion 10a so that even if a large thermal deformation occurs, the bolts and a clamped portion 10b located in contact with a hollow metal O-ring 1 are scarcely deformed and only the groove portion is deformed. The temperature difference between the inside and outside of the grooved portion 10b is small. Since the number of times of baking in a high-degree vacuum container or the like is small in general, the yielding of the grooved portion 10a could occur only in its surface part and cause little trouble to the whole body. Because the width of the groove 10a is small, the increase in the quantity of deformation of a flat lid 10 due to pressure or load is minute.

Title: Manufacture of pare-earth-iron-nitrogen permanent magnet
Inventor: MAKITA AKIRA
IPC: H01F1/08
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain a large-sized high-density rare-earth-iron-nitrogen permanent magnet which causes little cracking and chipping, by compressing 2-17 series R-Fe-N compound powder having a specific composition with a cylindrically converged impulsive wave after compression-molding the powder. SOLUTION: A rare-earth-iron-nitrogen permanent magnet is manufactured by using powder having a composition expressed by RXT100-X-YNY (where, R and T respectively represent one or two or more kinds of rare-earth elements containing at least >=50% Sm and Fe or Fe partially replaced with <=20% Co, Cr, or Co and Cr and X and Y respectively represent at.%) and meeting relations, 9<=X<=12 and 10<=Y<=16. Then a compressed body 1 having an apparent density which is 40-90% of the true density of the body 1 is obtained by compression-molding the powder by increasing the packing density of the powder so as to easily suppress the temperature rise of the powder. A capsule 2 is placed on a base 4 and surrounded by a cylindrical explosive container 5 made of an acrylic resin and an explosive 6 is packed between the capsule 2 and container 5.  After a detonating charge 7 is put in the container 5 and a fuse 8 is connected to the charge 7, the whole body of the container 5 is buried in the ground and the compressed body 1 is impactively compressed by initiating the explosives 7 and 6. When the explosives 7 and 6 are exploded, compression pressure which converge toward the center of concentric circles are generated.

Abstract: PURPOSE:To prevent generation of chattering in gears by providing a friction clutch on a shaft driving a power generating unit by means of a main engine shaft and automatically giving a slip to the friction clutch after detecting fluctuation of rotational speed when this fluctuation occurs in the main engine shaft. CONSTITUTION:A propeller 4 is rotated by operation of the main engine 1 through a thrust shaft 3 and a power generator 9 is given through a speed increasing gear unit 8 at the time of engagement of a friction clutch 7. In this case, fluctuating rotational speed on the side of an input shaft 6 and the mean rotational speed are obtained by a fluctuating width arithmetic unit 14 from the output of a rotational speed detector 10 on the input side of the friction clutch 7. And the rotational speed fluctuating width obtained by comparing both speeds with eath other is compared with a set signal 15 and the slip amount proportional to the fluctuating width is computed. Next, either of higher value out of the slip amount and the maximum allowable slip ratio setting signal 17 is selected by a selecting nit 16 and given to a slip amount comparing unit 23 as a set signal. Then it is compared with real slip amount from a slip arithmetic unit 21, and the friction clutch 7 is controlled in accordance with thus obtained deviation.
