Patent number: 8418379Abstract: A shoe sole of the present invention includes a first member 10 including a first deformable portion 11, and a second member 20 including a second deformable portion 21. In a non-worn state, a first lower surface 10d of the first deformable portion 11 and a second upper surface 20u of the second deformable portion 21 are substantially spaced apart from each other in a vertical direction. Under a first load, the first deformable portion 11 deflects downward, whereby the first lower surface 10d can approach the second upper surface 20u until the first lower surface 10d contacts the second upper surface 20u. Under a second load, the deformable portions 11 and 21 both deflect downward with the engagement elements 12 and 22 of the deformable portions 11 and 21 engaging with each other.Type: GrantFiled: November 3, 2011Date of Patent: April 16, 2013Assignee: Asics CorporationInventors: Tsuyoshi Nishiwaki, Yosuke Ootsuka, Satoshi Kiso

Patent number: 6550318Abstract: An abnormality diagnosis apparatus for performing a leak check of an evaporative fuel processing system which includes a fuel tank, a canister for storing evaporative fuel generated in the fuel tank, a purging passage for connecting the canister to an intake system of an internal combustion engine, and a purge control valve provided in the purging passage. A process of reducing the pressure in the evaporative fuel processing system is executed with a limited flow rate of gases passing through the purge control valve when performing the leak check in an idling condition of the engine. The limited flow rate is set to a value equal to or smaller than a predetermined flow rate which is smaller than the maximum flow rate applied to the leak check performed in operating conditions other than the idling condition. The leak check is performed on the basis of a change in the pressure in the evaporative fuel processing system after the pressure reduction process.Type: GrantFiled: April 2, 2001Date of Patent: April 22, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Isobe, Manabu Niki, Kojiro Tsutsumi, Hiroyuki Ando, Takashi Iwamoto, Satoshi Kiso

Patent number: 5690076Abstract: An evaporative fuel-processing system for an internal combustion engine has an evaporative emission control system. An ECU carries out negative pressurization of the interior of the evaporative emission control system, by opening a purge control valve and closing a vent shut valve, and determines presence/absence of leakage from the evaporative emission control system, based on a rate of decrease in negative pressure within the system, by closing a purge control valve. Before the negative pressurization, the interior of the evaporative emission control system is opened to the atmosphere, and during the open-to-atmosphere, a pressure state within the fuel tank is estimated based on a rate of change in an output from a pressure sensor which senses pressure within the evaporative emission control system. The ECU determines whether the evaporative emission control system is normal, based on the estimated pressure state.Type: GrantFiled: March 1, 1996Date of Patent: November 25, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Akira Hashimoto, Hideo Moriwaki, Yoshiaki Matsuzono, Sachito Fujimoto, Satoshi Kiso

Patent number: 5678523Abstract: An evaporative fuel-processing system for an internal combustion engine has an evaporative emission control system and a pressure sensor. An ECU carries out negative pressurization of the interior of the evaporative emission control system, by opening a purge control valve and closing a vent shut valve. The purge control valve is closed over a predetermined time period after the interior of the evaporative emission control system is brought into the predetermined negatively pressurized state, and a rate of decrease in negative pressure within the evaporative emission control system is detected. Then, it is determined whether or not there is leakage from the evaporative emission control system, based on the detected rate of decrease in the negative pressure, and at least one detected pressure value at at least one predetermined time point within the predetermined time period over which the purge control valve is closed.Type: GrantFiled: March 1, 1996Date of Patent: October 21, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Akira Hashimoto, Hideo Moriwaki, Yoshiaki Matsuzono, Sachito Fujimoto, Satoshi Kiso
