Publication number: 20040170346Abstract: In a throttle valve device for an internal combustion engine, a stepped portion is formed on an outer peripheral surface of an inner ring on a bore side (on an air intake passage side) in order to limit movement of a lip portion of a first lip seal on the bore side toward an inside of a rolling bearing. Thus, even if a high supercharging pressure above an atmospheric pressure acts on the first lip seal, deformation and curling of the lip portion due to the supercharging pressure can be prevented. As a result, separation of a second lip seal on a gear cover side (on an outside) from the rolling bearing can be prevented.Type: ApplicationFiled: February 27, 2004Publication date: September 2, 2004Applicant: DENSO CORPORATIONInventors: Tetsuya Komeda, Hidetoshi Uchiyama, Masato Arai

Publication number: 20040031488Abstract: A secondary reservoir (16) is filled with a liquid medicine by a fixed amount via a liquid transfer path (18) from a primary reservoir (10) for storing the liquid medicine to be nebulized. When a liquid supply button (40) is slid to left, an operating rod (42) pushes a piston (20) and power supply switch turns on. As piston (20) moves to left, the liquid medicine in secondary reservoir (16) is pushed, thereby moving a valve (22) to left and opening a liquid transfer path (24). Then, a nebulizing part is supplied with the fixed amount of liquid medicine from secondary reservoir (16), and thus performs nebulization. Thus, a liquid nebulizing apparatus is attained, in which a constant amount of liquid is transferred to the nebulizing part to stabilize the nebulization, and in which such a function is realized at low costs.Type: ApplicationFiled: April 4, 2003Publication date: February 19, 2004Inventors: Takao Terada, Kei Asai, Masato Arai, Jutaro Nishimura, Makoto Tabata, Shinya Tanaka, Shinichi Itoh
