  • Patent number: 8584818
    Abstract: A piston connected to a piston rod is fitted in a cylinder having a hydraulic oil sealed therein. Flows of hydraulic oil induced by sliding movement of the piston are controlled by extension and compression damping force generating mechanisms and to generate damping force. In the extension damping force generating mechanism, the valve-opening pressure of a disk valve is controlled by the pressure in a back pressure chamber. An elastic seal member fixed to the disk valve is brought into sliding contact with an inner peripheral surface of a cylindrical portion of a valve member to seal the back pressure chamber. The disk valve is self-aligned by fitting between the elastic seal member and the inner peripheral surface of the valve member and secured by being axially clamped at an inner peripheral portion thereof in a state where a clearance is formed between the inner peripheral portion of the disk valve and a shaft portion of the piston rod, thereby reducing the requirements for coaxiality.

  • Patent number: 8557542
    Abstract: The present invention aims to synthesize a polypeptide having an unnatural structure at the N-terminus via a biosynthetic process by translation of amino acid sequence information encoded by a nucleic acid. A polypeptide having any amino acid at the N-terminus is synthesized by using an ARS ribozyme that catalyzes the acylation of tRNA with any amino acid to attach any amino acid to an initiator tRNA, thereby initiating a translation with the initiator tRNA.

  • Patent number: 8413774
    Abstract: The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve to generate damping force. The valve opening of the main valve is controlled by adjusting the pressure in a pilot chamber through the pilot valve. A volume compensating chamber is defined by a flexible disk member so as to face the pilot chamber. The volume compensating chamber is communicated with a reservoir through communicating passages. When the disk valve opens, the volumetric capacity of the pilot chamber reduces. At this time, the flexible disk member deflects toward the volume compensating chamber, thereby suppressing an excessive rise in pressure in the pilot chamber and preventing an unstable operation of the pilot valve and the main valve to obtain a stable damping force.

  • Patent number: 8348027
    Abstract: The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve, which is a pressure control valve, thereby generating damping force. By thrust from a solenoid actuator, the valve-opening pressure of the pilot valve is controlled, and the pressure in a pilot chamber is also controlled to control the valve-opening pressure of the main valve. When there is a failure, a valve body of the pilot valve is retracted to abut against a fail-safe disk by spring force of a valve spring. Thus, damping force is generated by the fail-safe disk at the downstream side of the pilot valve, and the valve-opening pressure of the main valve is also controlled by the fail-safe disk to obtain an appropriate damping force.
