Patent number: 10374269Abstract: A battery pack includes a plurality of battery stacks integrated by stacking a plurality of unit batteries, a fluid passage where fluid flows for cooling the unit batteries disposed between the battery stacks, a blower for circulating the fluid in the fluid passage, and a plurality of heat conducting plates. The heat conducting plate is thermally connected to an outer casing of the unit batteries constituting the battery stacks adjacent to each other, and disposed so as to constitute a plurality of cooled portions of which parts thereof exist in the fluid passage. The battery pack includes a passage forming member that demarcates the fluid passage as an independent passage from the area near the outer casing of the unit battery, and includes a partition wall for supporting the heat conducting plate.Type: GrantFiled: July 10, 2015Date of Patent: August 6, 2019Assignee: DENSO CORPORATIONInventors: Masaki Uchiyama, Ryuichiro Shinkai, Yoshimitsu Inoue, Takahiro Souki, Kouhei Yamamoto, Kouhei Yamaguchi, Tetsuya Goto

Patent number: 9166262Abstract: A battery pack includes battery modules each having a battery cell and a battery case housing the battery cell therein. The battery modules are stacked in a stacking direction so that a cooling passage for allowing a cooling medium to flow is defined between opposed surfaces of adjacent battery cases. One of the opposed surfaces has first ribs projecting toward the other of the opposed surfaces and extending parallel to each other along the one. The other of the opposed surfaces has second ribs projecting toward the one of the opposed surfaces and extending parallel to each other along the other. In the cooling passage, the first ribs and the second ribs intersect each other and end portions of the first ribs and end portions of the second ribs are in contact with each other in the stacking direction.Type: GrantFiled: September 21, 2011Date of Patent: October 20, 2015Assignee: DENSO CORPORATIONInventors: Takahiro Souki, Teruhiko Kameoka, Manabu Yamada, Shinjirou Shimizu, Naoya Hata, Masaki Itagaki, Yoshimitsu Inoue

Publication number: 20040207501Abstract: A wound coil member alternately includes first ring layers and second ring layers in a row. The first ring layer is formed in a manner that a coil wire is concentrically and inwardly wound by the given number of turns. By contrast, the second ring layer is formed in a manner that the coil wire is concentrically and outwardly wound by the certain number of turns. Here, a portion of the coil wire that transfers between the first ring layers and second ring layers does not cross over, but only runs upon any adjacent portions of the coil wire. As a result, even after the wound coil member is compressed, the compressed coil member does not easily involve a local deformation. Breakage of the coil wire, reduction of the cross sectional area, or damage of the coating can be thereby restricted.Type: ApplicationFiled: April 16, 2004Publication date: October 21, 2004Inventors: Takahiro Souki, Shinji Makita, Akito Akimoto, Kenichi Kita, Tomokazu Nakamura

Patent number: 6768215Abstract: In an engine starter of the present invention, a driving shaft to output a rotating force and a crankshaft of an engine are linked continuously. The engine starter comprises a one-way clutch to prevent an overrun of an armature after the engine starts. In the one-way clutch, a connecting rotation number in which an inner ring and an outer ring change from a disconnected state to a connected state in a decreasing process of engine revolutions is set above a lower limit of the engine revolutions above which the engine under suspension of the fuel supply is able to get restarted by itself by resuming of fuel supply. Therefore, the engine is always able to get restarted quickly even in a low-rotation range.Type: GrantFiled: August 2, 2002Date of Patent: July 27, 2004Assignee: Denso CorporationInventors: Takahiro Souki, Akira Kato, Masaru Kamiya, Keisuke Tani, Kazuo Masaki

Patent number: 6702718Abstract: An engine control apparatus includes a brake depression degree detecting device for detecting a degree of depression of a brake pedal in a vehicle. A brake depression degree judging device operates for judging whether or not the detected degree of depression of the brake pedal is smaller than a prescribed value. A deceleration detecting device operates for detecting a deceleration of the vehicle. An automatic engine stop and restart controlling device operates for automatically stopping an engine powering the vehicle when the deceleration detecting device detects a deceleration of the vehicle and the brake depression degree judging device judges that the detected degree of depression of the brake pedal is not smaller than the prescribed value.Type: GrantFiled: January 25, 2002Date of Patent: March 9, 2004Assignee: Denso CorporationInventors: Keisuke Tani, Akira Kato, Masaru Kamiya, Takahiro Souki

Patent number: 6672267Abstract: An engine-starting apparatus includes an electric motor and an overrunning clutch that transmits a rotational torque of the electric motor to an internal combustion engine. A coupling speed for re-coupling the clutch for re-cranking the engine while it is still rotating by the inertia is set to a point where an inertial speed of the engine becomes equal to or a little higher than an inertial speed of the electric motor. The electric motor is switched on again when its speed decreases to the coupling speed or lower. In this manner, shocks and noises generated in the re-coupling of the clutch are avoided, and the engine can be smoothly re-cranked while it is still rotating by its inertia.Type: GrantFiled: May 23, 2002Date of Patent: January 6, 2004Assignee: Denso CorporationInventors: Takahiro Souki, Akira Kato, Masaru Kamiya, Keisuke Tani, Masahiko Osada

Patent number: 6135920Abstract: An engine automatic speed control apparatus which exhibits a smooth transition from brake release to an engine drive state. An ECU determines braking force such that a vehicle does not move in correspondence with the slope of a road surface according to a road surface slope sensor while monitoring an operated quantity of a brake pedal according to a brake pedal operated-quantity sensor. The ECU stops an engine when braking force is applied via the brake pedal such that the vehicle does not move. After stopping the engine, the ECU determines braking force such that the vehicle does not move in correspondence with slope of the road surface according to the road surface slope sensor, and restarts the engine when braking force becomes less than braking force required to maintain the vehicle in a stopped state. The ECU then restarts the engine in the interval from relaxing of braking force via the brake pedal until the brake pedal is released.Type: GrantFiled: June 18, 1999Date of Patent: October 24, 2000Assignee: Denso CorporationInventors: Masaru Kamiya, Akira Kato, Takahiro Souki

Patent number: 5959385Abstract: A rotary shaft of a starter motor drives a crankshaft through an overrunning clutch and a rotary shaft of a generator. When an engine is started, the crankshaft drives a driven member of the overrunning clutch through the rotary shaft of the generator. A centrifugal member of the overrunning clutch separates a torque transmitting unit from the drive member or driven member of the overrunning clutch when the engine runs at a high speed to prevent wear of the overrunning clutch.Type: GrantFiled: October 18, 1996Date of Patent: September 28, 1999Assignee: Denso CorporationInventors: Akira Kato, Takahiro Souki

Patent number: 5876298Abstract: A speed reduction device including an overrunning clutch has a drive shaft having an eccentric ring and an inner gear plate disposed to be rotatable relative to the eccentric ring. The gear plate has a plurality of teeth and engagement holes. The device further has fixing pins fixed to the housing in engagement with the engagement holes of the inner gear plate to restrict rotation of the inner gear plate to thereby allow swinging of the gear plate, an outer ring disposed around the inner gear plate and connected to a driven shaft and a torque transmitting member which engages the teeth of the inner gear plate to transmit torque from the inner gear plate to the outer ring. The torque transmitting member is arranged to disengage the teeth of the inner gear plate by centrifugal force when the outer ring rotates at a speed higher than a threshold value.Type: GrantFiled: June 27, 1997Date of Patent: March 2, 1999Assignee: Denso CorporationInventors: Akira Kato, Takahiro Souki, Masaru Kamiya
