Title: Form rolling method of gear
Inventor: AIZAKI MASARU
IPC: B21H5/00
Filed: 1982-11-29
Abstract: PURPOSE:To improve remarkably the accuracy of a tooth profile and tooth trace in the stage of pressing rolling tools to a blank material and generating a gear by reversing intermittently the relative rotating direction applied on the blank material to level off the twist parts formed on both sides in a unit tooth part. CONSTITUTION:A blank material for a gear is freely rotatably supported between rolling tools positioned oppositely to each other, and the tools are driven to rotate so that the tooth profile is generated on the blank material while the material is pressed by the tools. An under fill 1ta is produced by the metallic flow heading toward the center in the tooth part on the driven side of the tooth ta of a blank material G2 and a twist part 2ta is produced by the metallic flow heading toward the tip and deddendum on the follower side in the stage (a) when the tools are rotated as required. The force acting on the tooth tb is reversed and the twist at the projecting part 2tb is suppressed on the driven side and a twist part 1tb is produced on the follower side in the stage (b) when the material G2 is rotated reverse. The rotation of the tools is thereafter changed periodically to form the tooth td having no deviation at the tip. The blank material is thus rolled to the tooth profile having a balanced shape.

Inventor: OYAMA HIDEMI
IPC: E04H9/02
Filed: 1990-08-09
Abstract: PURPOSE:To reduce maximum acceleration generated at an upper structure, for an isolator for fine vibration, provided with a modified restraint member by arranging a buffer member, the rigidity of which is larger than that of the isolator, and is smaller than that of the modified restraint member, on the modified restraint member. CONSTITUTION:In a vibrationproofing isolator comprising an isolator A for fine vibration and an isolator B for large vibration, the isolator A is provided with a large tenon pin 4 as a modified restraint member.

During a large earthquake, at the time of the large tenon pin 4 coming into contact with the flange 1 of the isolator A, the deformation of the isolator A for fine vibration is smoothly transformed to that of the isolator B for large vibration, due to the operation of the buffer member 10. The maximum acceleration generated on an upper structure is reduced thereby, and a vibrationproofing effect can thus be obtained.

Title: Master cylinder provided with reservoir
Inventor: SAITO TSUTOMU
IPC: B60T11/22
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a master cylinder, in which a reservoir is provided, no machining for preventing a slip-off of a sealing member from a cylinder main body is required, and assembly between the cylinder main body and the reservoir can be facilitated. SOLUTION: A distance L1' between a connecting member 23, which connects a cylinder main body 21 and a reservoir 22 together, and a tilt preventing unit 31, which prevents a tilt of the reservoir 22, is set to be longer than a distance L2' between the connecting member 23 and a communication unit 30, which feeds working fluid inside the reservoir 22 to a hydraulic chamber 28 arranged inside the cylinder main body 21. In this way, a reaction force in the tilt preventing unit 31 works on the communication unit 30 while using the connecting member 23 as a fulcrum when an external force works on the reservoir 22, so that a high sealing force corresponding to a distance ratio of the distance L1' between the distance L2' can be obtained.  As a result, machining for preventing a slip-off of the sealing member in the cylinder main body 21 can be dispensed with, and assembly between the cylinder main body 21 and the reservoir 22 can be also facilitated.

Filed: 1988-08-25
Abstract: PURPOSE:To give the extent of constant tension to a long material at all times as well as to perform its working in optimum conditions by constituting a degree of torque requisite for rotation of a rotary plate of a magnetic torque controller so as to be smaller in proportion as a distance between an elastic pressure roller, pressing an outer circumferential surface of the long material rolled on a drum, and a turning shaft installed solidly with this drum becomes shorter. CONSTITUTION:When a long material 4a rolled on a drum 13 is drawn out, torque conformed to a pair of permanent magnets 9 requisite for rotating a rotary plate 8 of a magnetic torque controller 6 becomes smaller in proportion as a distance L between an elastic pressure roller 14, being attached to the tip of a rocking arm 17 of a rocker shaft 16 and pressing an outer circumferential surface of the long material 4a, and a turning shaft 5 installed as one body with the drum 13 becomes shorter according to an amount of the long material 4a. Consequently, according as thickness of the long material 4a rolled on the drum 13 becomes smaller, the torque requisite for rotating the turning shaft 5 is made smaller, therefore constant tension is always given to the long material 4a drawn out of the drum 13 attached to an uncoiler as a result.
