Publication number: 20050263363Abstract: In the disclosed hydraulic shock absorber, the flow of hydraulic fluid induced in each of extension and compression hydraulic fluid passages by sliding movement of a piston is controlled by a main disk valve to generate damping force. The valve opening pressure of the main disk valve is adjusted by the pressure in a back-pressure chamber. In a low piston speed region, the main disk valve closes a back-pressure chamber inlet passage. Therefore, the pressure in the back-pressure chamber will not rise, and sufficiently small damping force is obtained. When the main disk valve opens, the back-pressure chamber inlet passage opens simultaneously. Consequently, the pressure in the back-pressure chamber rises, and the damping force increases.Type: ApplicationFiled: May 23, 2005Publication date: December 1, 2005Inventors: Hajime Katou, Hikaru Nakajima, Takao Nakadate

Patent number: 6737021Abstract: Multiple piezoelectric elements 35 are arranged in a row along the top of liquid level in a reaction vessel 11. An ultrasonic reflecting material 38 is installed on the bottom of the portion of the heat insulating bath 12 where heat insulating medium 13 is stored. A lateral ultrasonic wave 9b is generated on the lower side by actuation of the piezoelectric element 35. Wave 9b is reflected by the ultrasonic reflecting material 38. As lower ultrasonic wave 8 advances along the wall surface of the reaction vessel, it collides with the specimen liquid, thereby causing a portion of the liquid level closer to the piezoelectric element 35 to be raised. When lateral ultrasonic wave 9a is applied to this portion, it reaches the inclined portion of the raised liquid level of the specimen. Swirling flow by agitation 36 is produced by acoustic radiation pressure of the ultrasonic wave. The specimen and reagent are mixed and agitated by this swirling flow.Type: GrantFiled: February 22, 2001Date of Patent: May 18, 2004Assignee: Hitachi, Ltd.Inventors: Shigenori Watari, Hajime Katou, Katsuhiro Kambara, Hiroyasu Uchida, Takeshi Shibuya
