Abstract: An internal combustion engine includes a port injection valve, a direct injection valve, and a forced-induction device. A ratio of an amount of fuel injected from the port injection valve with respect to a total amount of fuel supplied for one fuel combustion in the cylinder is defined as a port injection ratio. The internal combustion engine is controlled such that, in a case in which a condition is satisfied that the forced-induction device is in an operation of performing forced induction and the internal combustion engine is in an engine operation region in which a valve overlap period is greater than zero, the port injection ratio is set to be small and a start timing of fuel injection from the port injection valve is delayed as compared with a case in which the condition is not satisfied.

Abstract: A field effect transistor comprising: a non-doped diamond layer which has a hydrogen-terminated surface; first and second p+diamond layers which are formed on the non-doped diamond layer and sandwich a hydrogen-terminated region; a source electrode which is formed on the first p+diamond layer and is made of metal; a drain electrode which is formed on the second p+diamond layer and is made of metal; an insulating layer which is formed on the hydrogen-terminated region of the non-doped diamond layer; and a gate electrode which is formed on the insulating layer, a mutual conductance being equal to or higher than 0.5 mS/mm at room temperatures, after an X-ray is applied for an amount of 5 Mgy.

Abstract: A smoke detector includes: a casing; a first light emitting unit; a second light emitting unit; and a light receiving unit. A second scattering angle that is an angle between the reception axis of the light receiving unit and a second extension extending from an intersection of the second emission axis and the reception axis in a direction away from the second light emitting unit is larger than a first scattering angle that is an angle between the reception axis of the light receiving unit and a first extension extending from an intersection of the first emission axis and the reception axis in a direction away from the first light emitting unit.

Abstract: A system for managing a selling system for shipping out an item from a warehouse or a nearest base associated with a delivery destination, includes an instruction unit configured to, before receiving an order placement for an item from a customer, transmit, to a warehouse server associated with the warehouse or a relay base server associated with a relay base, a transportation instruction for transporting the item to the nearest base from the warehouse or the relay base, and to, after receiving the order placement for the item from the customer, transmit, to a nearest base server associated with the nearest base, a submission instruction for submitting the ordered item to the customer.
