Patent number: 11874075Abstract: A heat exchanger includes a main body provided with first flow paths through which a first fluid flows and second flow paths through which a second fluid flows. Each first flow path includes an integrated part, a buffer part, and a divided part arranged in this order from an inlet of the main body. The integrated part includes a first flow path space defined by a peripheral wall including a pair of mutually facing partition walls. The buffer part includes a deformed flow path space formed by deforming the first flow path space such that first displacement parts or each of multiple pairs of first displacement parts provided at intervals on the pair of partition walls approach each other. The divided part includes multiple divided flow path spaces formed by dividing the first flow path space by connecting the first displacement parts of each pair to each other.Type: GrantFiled: February 22, 2022Date of Patent: January 16, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Tsuneo Endo, Katsutoshi Tada, Hitomi Ito, Yuta Kurosawa

Patent number: 9022458Abstract: A side panel for an automotive body includes a unitary panel having a side sill, a roof rail, and a pillar integrally joined to each other. The pillar extends from the side sill to the roof rail, and each of the side sill, the roof rail, and the pillar are made of fiber-reinforced plastic. At least one of the side sill, the roof rail, and the pillar has a recess concave transversely outwardly relative to the automotive body. The recess has an opening that opens transversely inwardly relative to the automotive body. The recess is defined by two side walls bent from flanges and extending transversely outwardly relative to the automotive body, and a bottom wall joined to the side walls. The side walls have portions joined to the flanges, the portions of the side walls being thicker than the bottom wall.Type: GrantFiled: February 27, 2014Date of Patent: May 5, 2015Assignee: Honda Motor Co., Ltd.Inventors: Kazuhide Hasegawa, Wakato Yamamoto, Katsutoshi Tada

Publication number: 20130283959Abstract: A brake handle assembly for an aircraft emergency/parking brake includes a handle movable between a non-actuated position wherein the brake is disengaged and a full actuated position wherein, during movement therebetween, the brake applies a modulated braking force in an emergency brake state. A button actuator is disposed on the handle. Movement of the handle from the intermediate stop position to the full actuated position is obstructed to prevent inadvertent operation of the brake in the parking brake state unless the button actuator is depressed.Type: ApplicationFiled: October 14, 2011Publication date: October 31, 2013Applicant: HONDA PATENTS & TECHNOLOGIES NORTH AMERICA, LLCInventors: Hiroki Oyama, Katsutoshi Tada, Charles T.

Patent number: 7707924Abstract: A groove is provided to the rear of an inner wall of a cylinder. A locking ram capable of freely sliding in a radial direction and a cam rod having a profile changing with a transition from the rear to the front from a small diameter part to a large diameter part that are provided relative to a piston. The inner end of the locking ram makes contact with the profile, and the cam rod is urged to the rear by the spring, so that the cam rod can be pushed to the front by a push rod. The piston can therefore be locked with a simple structure, and it is possible to provide a linear actuator where locking can be released with a straightforward operation even when a pressurized oil source fails.Type: GrantFiled: February 23, 2005Date of Patent: May 4, 2010Assignees: Honda Giken Kogyo Kabushiki Kaisha, Sumitomo Precision Products Co., Ltd.Inventors: Hiroshi Yamanouchi, Katsutoshi Tada, Masaru Oono, Tetsuji Sato

Patent number: 6796535Abstract: In a flap operating system, left and right actuators for operating left and right flaps are synchronized with each other by left and right pulleys and first and second synchronizing cables wound in an X-shape around the left and right pulleys. If one of the hydraulic actuators fall into a free failure or fails due to sticking, a difference is generated between the rotational angles of the left and right pulleys. When the difference exceeds a threshold value, the operations of the left and right actuators are stopped, whereby an excessive load is previously prevented from being applied to a main wing structure or the flap operating system.Type: GrantFiled: June 11, 2003Date of Patent: September 28, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Minoru Uchida, Hiroshi Yamanouchi, Katsutoshi Tada

Patent number: 6530272Abstract: A first cylinder drives a flap to a predetermined down position. Strain gages detect strains at each part of the flap while a load that corresponds to the down position is applied to the flap by a second cylinder that has been moved by an XY table so as to track the down position. Accordingly, actual aerodynamic forces are precisely reproduced by applying a load having a size and a direction that correspond to the down position of the flap. Thus, a stationary load test, a dynamic load test, and a durability test of the flap can be carried out automatically with a small effort and in a short time.Type: GrantFiled: November 6, 2001Date of Patent: March 11, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Minoru Uchida, Hiroshi Yamanouchi, Wataru Yada, Katsutoshi Tada

Patent number: 6464175Abstract: A flaperon operating device having a center pulley and a slider supported on a center shaft. When the center pulley and the slider are rotated about the center shaft, left and right driving pulleys are rotated in the same direction, whereby left and right flaperons are operated in opposite directions to provide aileron functions. When the slider is slid rearwards on the center shaft by an actuator, the left and right driving pulleys are rotated in opposite directions, whereby both the left and right flaperons are lowered to provide flap functions. If the left and right flaperons are lifted or lowered by a very small angle in the same phase by the actuator, boundary layers on main wings can be controlled to reduce the drag.Type: GrantFiled: July 13, 2001Date of Patent: October 15, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Wataru Yada, Hiroshi Yamanouchi, Minoru Uchida, Katsutoshi Tada
