Inventor: HIRAI TAKASHI
IPC: B21D53/24
Filed: 1993-08-31
Abstract: Disclosed is a method of manufacturing an improved screw washer, an improved screw washer, and an improved mold for fabricating the improved screw washer. Using a selected metal plate having thickness thinner than nominal height demanded for a nut, the invention primarily aims to form an improved screw washer incorporating a nut satisfying the demanded height. The second object of the invention is to provide an improved method of manufacturing an improved screw washer, the improved screw washer, and an improved mold for fabricating the screw washer. Practically, using this improved mold, the improved screw washer can easily be manufactured, where the above-identified nut is solidly bonded with the metal plate without being disengaged therefrom, and yet, a sufficiently lengthy tapped hole is formed. 
     Structurally, a nut 3 is formed in the state being continuous to a metal plate 2 after punching out part of the metal plate 2. The nut 3 is further punched in order that a punched hole 7 having diameter narrower than inner diameter of a tapped hole 4 can be formed in the center of the nut 3, and finally, the tapped hole 4 is formed in the nut 3 in the manner being coaxial with the punched hole 7.

Abstract: A differential pressure operated valve (10) for use as a circulating and/or deflation valve in a well bore, comprises a housing (48) defining first (74) and second (78) bores therethrough and a passage (70) providing communication between the interior and exterior of the housing. A valve sleeve (86) is slidably disposed in the housing (48) and has a first outer surface (88) slidably disposed in the first bore (74) and a second outer surface (92) slidably disposed in the second bore (78). A valve port (96) is defined in the valve sleeve (86) providing communication between a central opening thereof and the passage in the housing when the valve sleeve is in an open position. When the valve sleeve is closed, the valve port (96) and passage are isolated from one another. The first (88) and second (92) outer surfaces of the valve sleeve (86) define a differential area, and the valve is closed by fluid flow creating a differential pressure acting across this area. A spring (102) biases the valve toward the open position.

Abstract: L'invention concerne une variante d'hirudine présentant la séquence correspondant au numéro d'identification de séquence 1. L'invention concerne en outre un ADN codant pour la séquence d'acides aminés de la variante, un vecteur d'expression, un colibacille de recombinaison, et un procédé permettant de produire ladite variante au moyen du colibacille. Un anticoagulant contenant ladite variante comme ingrédient actif est également décrit. Etant donné que cette variante ne présente pas la séquence Asp33-Gly34- ou bien Asp62-Ala63- contenue dans les séquences d'acides aminés de l'hirudine et de ses variantes classiques, elle peut inhiber la formation du dérivé de succinimide et du dérivé résultant du beta-transfert due à la séquence susmentionnée, et elle présente une grande stabilité ainsi qu'une importante activité antithrombinique, ce qui lui permet d'être utilisé comme anticoagulant. En outre, une variante d'hirudine possédant la séquence représentée par le numéro d'identification de séquence 1, dans laquelle la séquence VAl1-VAl2- contenue dans la séquence d'acides aminés des variantes de l'hirudine classiques a été remplacée par la séquence Ile1-Ile2-, présente une activité antithrombinique très importante qui convient particulièrement à son utilisation en tant qu'anticoagulant.

Abstract: The provision of an electric rotating machine which can reduce the mechanical and thermal loads applied thereto. Coil arms (534, 537, 20b, 21b, 20d, 21d) and coil trunks (533, 536, 20e, 21e) are provided in roughly parallel orientation to the end faces of an armature core (520, 11) only through insulating rings or spacers (560, 590, 20a, 21a, 20c, 21c). Metal brush (910, 81) is disposed on coil arms, whereby the overall length of the armature can be remarkably shortened. In addition, a commutator, conventionally necessary, can be eliminated, whereby the length of the production process for the armature can be reduced. Moreover, in an arrangement where projections (534c) of the upper coil arm are fit in holes of the insulating spacer, as the displacement of the upper coil arm towards the outer periphery is regulated, the length of axial protrusions of the upper coil arm from the end face of the armature core can be minimized. In addition, as extension portions (538, 20g, 20h) and of the coil trunks are strongly pressed against and fixed to the side of armature core by fixing members (570, 30), the resistance to the centrifugal force can be remarkably improved. Furthermore, as the extension portion of the lower coil arm is fit in a recessed part of the insulating spacer, the displacement of the lower coil arm in the axial direction towards the outer periphery can be prevented.
