Title: Center hole machining device for crankshaft
Inventor: HASEGAWA TAKESHI
IPC: B23B5/00
Filed: 1988-04-05
Abstract: PURPOSE:To form a center hole with high precision, by a method wherein when a crankshaft is rotationally driven around the axis of a journal part, a rotary tool is pressed against the end surface of the crank shaft to drill the center hole. CONSTITUTION:A crankshaft 8 is rotatably supported by a support device, and center hole correction machining is applied on two end surfaces in a way that a cutter 66 for correcting a center and a combination tool 94 are moved forward as the crankshaft 8 is rotated around the axis of a journal part by means of a rotational drive means. Thus, even if the axis of the journal part is displaced from the central lines of the cutter 66 for correcting a center and the combination tool 94 due to the size error of the journal part, machining thereof is effected around the axis of the journal part. This constitution enables the corrected two holes to coincide with the axis of the journal part with high precision, and permits improvement of stroke precision of a crank pin 12.

IPC: H01M8/24
Filed: 1994-04-22
Abstract: PURPOSE:To keep phosphoric acid from entering between a cell-stack and a tightening plate therebelow so as to prevent corrosion of the current-carrying surface of the tightening plate by projecting the surface of the lower tightening plate that makes contact with the cell-stack, making the surface smaller in area than the cell-stack, and providing a gap between the surface and the outer periphery of the bottom of the stack. CONSTITUTION:A portion of a lower tightening plate 2b which serves as a current-carrying surface on contact with a cell-stack 1 is made greater in area than the stack 1, and is projected so that a gap forms between the plate and the outer periphery of the stack 1. Therefore, even if phosphoric acid impregnating unit cells flows down along the side surface of the stack 1 and reaches the tightening plate 2b, the phosphoric acid does not make contact with the surface of contact between the stack 1 and the tightening plate 2b.

IPC: B65H29/22
Filed: 1986-04-15
Abstract: PURPOSE:To make it possible to prevent the insertion of sheet onto a press plate from being hindered, in a feeder in a cut-sheet feeder type printer, by associating a separating pawl member with the depressing motion of the press plate so that a predetermined gap is held between the separating pawl and the pressing plate. CONSTITUTION:There are provided, in a feeder, a means for pulling a press plate 47 in parallel when sheets which are aligned together are loaded on the press plate 43, and a means for rotating a separating pawl member 45 about a shaft pin 45B to pull up the separating pawl 45. Accordingly, when the press plate 43 is depressed to feed sheets, a resilient arm section 61 of the press plate 43 depresses downward an extending arm section 60 of the separating pawl member 45, overcoming the force of a press plate spring 47, and therefore, the lever action of the member 45 causes the front end of the pawl separating member to be raised in the direction Y. In this arrangement, a stopper 45C on the member 45 abuts against the flange section of a feed roller base, and therefore, sufficient gaps are maintained among a separating pawl 45A and a paper sheet roller which is not shown, and the press plate 43, thereby it is possible to set a bundle of sheets without hindrance.

Abstract: PURPOSE:To smoothly reproduce CDs by inserting a disk driving shaft into a driven cylinder and a push-up cylinder, fixing a plural-CD feed rotary disk to the driven cylinder and fixedly providing a CD center holder part underneath a circular orbit on the outer circumferential side of the disk. CONSTITUTION:The disk driving shaft 7 is inserted into the driven cylinder 13 and the push-up cylinder 12, where the cylinder 13 is inserted into the plural-CD feed rotary disk 1 to be fixed, and the shaft 7 is driven to rotate by a motor 18, etc. The disk 1 is provided with CD receiving frames 8 in plural holes in a circumference. When an opening and closing lid shaft (integrated with a push-up arm) 10 is opened, the cylinder 12 is lifted by the push-up arm 9 so that the cylinder 13 fixed with the disk 1 is positioned in the most upper part of the shaft 7 to make the disk 1 freely rotatable. When the opening and closing lid is closed, the arm 9 is lowered downward, and in interlocking with this, the cylinder 12 is lowered, and the cylinder 13 is automatically lowered by gravity as well, so that only a center part of an instructed and selected CD is automatically fitted onto the center holder part positioned just underneath the center part. By this method, when several spares of the disks are prepared and set, the practical use of a great number of CDs can easily be handled only by changing the disks.
