Patent number: 10971920Abstract: An overcurrent protection device is to be provided between a power supply and a load circuit including an electric load and an electric wire electrically connected with each other, and includes a switching element, a current detector, a characteristic estimation portion, and a controller. The switching element switches flowing and interrupting of a load current that flows from the power supply to the electric load. The current detector detects the load current. The characteristic estimation portion estimates a thermal characteristic of the electric wire based on the load current detected by the current detector. The controller outputs an overcurrent protection signal for interrupting the load current so as to protect the load circuit from an overcurrent to the switching element based on the thermal characteristic estimated by the characteristic estimation portion and the load current detected by the current detector.Type: GrantFiled: August 21, 2018Date of Patent: April 6, 2021Assignees: DENSO ELECTRONICS CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomokatsu Fuseya, Naoyuki Yasuda, Manabu Morita, Jiro Ito, Shinji Oshita

Patent number: 10261532Abstract: A load drive circuit is configured to control driving of an electric load that is a direct current load, and includes a controller, a switching element, and a current detection portion. The controller generates and outputs a control signal for controlling a flowing state of a load current that flows to the electric load. The switching element switches flowing and interrupting of the load current based on the control signal. The current detection portion detects the load current. The controller includes a type determination portion and a control signal output portion. The type determination portion determines a type of the electric load based on the load current detected by the current detection portion. The control signal output portion generates and outputs the control signal based on the type determined by the type determination portion.Type: GrantFiled: August 21, 2018Date of Patent: April 16, 2019Assignee: ANDEN CO., LTD.Inventors: Naoyuki Yasuda, Tomokatsu Fuseya, Manabu Morita

Patent number: 9653853Abstract: An electric connection box includes a resin plate having a connector terminal soldered to a via hole of a circuit substrate. The circuit substrate and the resin plate are inserted to be housed in an opening part of a casing of the electric connection box. A housing is positioned in the opening part and functioning as a cover closing an opening side of the casing. The circuit substrate is supported by the housing and the casing through the resin plate that is held between the housing and the casing while the circuit substrate is spaced from the housing and the casing.Type: GrantFiled: March 1, 2016Date of Patent: May 16, 2017Assignee: Anden Co., Ltd.Inventors: Hideyuki Ohtani, Naoyuki Yasuda

Patent number: 9515652Abstract: In a relay module device, a signal converting section transmits driving signals of switching elements when receiving input signals from an external device and sets a relationship between the input signals and the driving signals. The relationship includes a first mode in which the signal converting section transmits the driving signals to separately control one of the switching elements with respect to one of the input signals, and a second mode in which the signal converting section transmits the driving signals to concurrently control two or more of the switching elements with respect to one of the input signals.Type: GrantFiled: January 27, 2015Date of Patent: December 6, 2016Assignee: Anden Co., Ltd.Inventors: Hideyuki Ohtani, Naoyuki Yasuda

Patent number: 6039071Abstract: When a valve body of a pressure-reducing valve is displaced in the direction indicated by the arrow B, a seal pad of a valve seal mechanism on the valve body abuts against a ridge on a seat, which enters the seal pad to provide a seal therebetween. When the ridge enters the seal pad by a distance, abutment surfaces of holders on the seat are held against the seal pad, preventing the ridge from entering the seal pad beyond the distance. The distance by which the ridge enters the seal pad is thus made constant. The ridge is spaced from the abutment surfaces by a groove, which communicates with a primary port through grooves between the holders, keeping a constant valve sealing area. The pressure-reducing valve which incorporates the valve seal mechanism has a constant quality level.Type: GrantFiled: May 27, 1998Date of Patent: March 21, 2000Assignee: SMC Kabushiki KaishaInventors: Taku Tomita, Mitsutoshi Araki, Naoyuki Yasuda

Patent number: 6024117Abstract: A recess and another recess having an enlarged diameter with respect to the recess are defined in a main body, wherein a valve guide body is inserted into the recess. Projections of the valve guide body engage inside grooves defined in a wall portion constituting the recess, and second projections of a cover member engage with first projections formed on a wall constituting the other recess, stopping the cover member from falling out. A pressure of a pressurized fluid which is imposed on the valve guide body is supported by the cover member. As a result, there is no concern of damage to the valve guide body, and moreover, there is no concern of unexpected dislocation of the valve guide body.Type: GrantFiled: July 10, 1998Date of Patent: February 15, 2000Assignee: SMC Kabushiki KaishaInventors: Taku Tomita, Mitsutoshi Araki, Naoyuki Yasuda
