Denso Corporation is a global automotive components manufacturer headquartered in the city of Kariya, Aichi Prefecture, Japan.After becoming independent from Toyota Motors, Nippon Denso Co. Ltd. was founded in 1949. Despite being a part of Toyota Group of companies, as of 2014, sales to Toyota Group accounts for less than 50% of the total revenue . Since 2009, Denso is the world's biggest auto-parts manufacturer by revenue.As of 2013 Denso Corporation consisted of 184 subsidiaries with a total of 132,276 employees. The company is further escalating its global production structure by establishing manufacturing complexes in India, Mexico and Indonesia in order to accommodate further global demand for their products. In 2013 Denso was listed at #242 on the Fortune 500 list with a total revenue of $43.1 billion. Wikipedia.

Denso Corporation | Date: 2017-01-27

A catalytic conversion characteristic of a catalyst, which indicates a relationship between an air-to-fuel ratio and a catalytic conversion efficiency of the catalyst, includes a second air-to-fuel ratio point, which is a point of starting an outflow of NOx from the catalyst and is located on a rich side of a first air-to-fuel ratio point that forms an equilibrium point for a rich component and oxygen. A constant current circuit, which induces a flow of an electric current from an exhaust side electrode to an atmosphere side electrode through a solid electrolyte layer in a sensor element, is connected to the sensor element. A microcomputer controls a current value of the electric current, which is induced by the constant current circuit, based on a difference between the first air-to-fuel ratio point and the second air-to-fuel ratio point at the catalyst.

An A/F sensor element includes a substrate made of an insulating ceramic having a bottomed cylindrical shape, an electrolyte part made of a solid electrolyte, and a pair of electrode portions. The electrolyte part is embedded in at least a portion of the side wall of the substrate. The A/F sensor element is used by inserting a rod-like heater in the substrate having the bottomed cylindrical shape. The substrate is formed of the insulating ceramic at a contact position to the heater within the substrate. In a manufacturing of the substrate, a molded body having a space for a forming position of the electrolyte part is formed by using substrate-forming clay, and then the molded body is molded by filling electrolyte-forming clay into the space.

A valve device includes: a ball valve (1) having a ball face (1a) shaped in a convex spherical surface; and a valve seat (2) having a seat face (2a) shaped in a concave spherical surface. The seat face is pressed onto the ball face. The ball valve is rotated to open a valve by communicating a valve opening (1 b) defined in the ball valve and a seat opening (2b) defined in the valve seat with each other, and to close the valve by stop the communication. A diameter of the seat opening 2 is smaller than a diameter of the valve opening 1. A curvature radius of the ball face R1 is smaller than or equal to a curvature radius of the seat face is R2.

Based on a determination at step 115 as to whether an intake refrigerant temperature Ts is at least -32C, and decisions at steps 145 and 150, either a normal operation or a speed control operation is performed. From a state where the intake refrigerant temperature Ts is less than -34C, which is when a speed reduction operation is performed, if the intake refrigerant temperature Ts reaches at least -32C but has not previously reached -20C, a limited speed operation is performed at step 155. During the limited speed operation, a maximum allowed rotational speed of a compressor (11) is limited to a predetermined speed lower than that of the normal operation. Under different circumstances, if the intake refrigerant temperature reaches at least -32C, the normal operation is performed at step 160.

A drive support apparatus includes: a reliability determiner determining a reliability of a map matching, an area definer defining a determination area to include a cross point between a self-vehicle predicted path and a nearby vehicle predicted path, an intersection node finder determining an intersection node in a travel direction of the self-vehicle based on a high map matching reliability, and a node determiner determining whether the intersection node is found in the determination area. When no intersection node is found in the determination area, a drive support level is suppressed, and when the reliability is low, drive support is provided depending on whether the cross point between the self-vehicle predicted path and the other vehicle predicted path is found. Thus, lack of the drive support in a support-required situation is prevented, while preventing a provision of an unnecessary drive support.

In a driving assistance apparatus, a detector is configured to detect whether or not a leading vehicle has started moving, where the leading vehicle is a vehicle just in front of an own vehicle and the own vehicle is a vehicle carrying the apparatus. A notifier is configured to, if it is detected by the detector that the leading vehicle has started moving, provide a notification that the leading vehicle has started moving. An inhibitor is configured to, when the own vehicle has approached a stop point along a road, at which every vehicle must stop before passing therethrough, inhibit the notifier from providing the notification that the leading vehicle has started moving.

A collision avoidance apparatus includes a control unit that is configured to perform a collision avoidance process. The control unit determines whether or not an object is present ahead of the own vehicle. When the control unit determines that an object ahead is present, the control unit determines whether or not there is a likelihood of a collision between the object ahead and the own vehicle and whether or not a corner is present ahead of the own vehicle. When the control unit determines that a corner is not present and when a predetermined collision avoidance condition is established, the control unit is capable of changing a travelling direction of the own vehicle to avoid collision between the object ahead and the own vehicle. When the control unit determines that a corner is present, the control unit does not perform a travelling direction change of the own vehicle.

In assisting merging vehicles on the road, a own vehicle is accelerated to target speed on a first lane. The own vehicle accelerated to the target speed is caused to change a travel lane from the first lane into a second lane. A distance A from the own vehicle to a reference position is acquired in the first lane, and speed of the own vehicle is also acquired. A traveling distance B required for the own vehicle to stop is calculated under a condition where the own vehicle traveling at speed acquired starts to slow down at predetermined deceleration. Assisting in merging is performed, on condition that a value obtained by subtracting the calculated distance B from the acquired distance A is smaller than a predetermined threshold value during a period from a start time of the acceleration to a start time of changing the travel lane.

An engine start system has a rotating electrical machine, a starter motor, an engine ECU and an ISG controller. The rotating electrical machine is connected to an output shaft of an engine. The starter motor drives the engine to be restarted. The engine ECU controls the engine operation. The ISG controller instructs an inverter when the rotating electrical machine performs power running and regenerative power generation. The ISG controller communicates with the engine ECU, and adjusts the operation of the starter motor and the rotating electrical machine. When receiving an engine restart request, the ISG controller drives at least one of the starter motor and the rotating electrical machine so as to restart the engine.
