Abstract: A stacked wafer to be subjected to singulation by stealth dicing, including a first layer in which a modified region is formable, a concave portion forming a space facing the first layer, a second layer that faces the concave portion and in which the modified region is not formed, and a third layer that faces the second layer and in which the modified region is formable, and a part of the second layer facing the concave portion is removed.

Abstract: An acquisition unit acquires pieces of information including information related to a vehicle, information related to the environment inside and outside the vehicle, and information related to a driver on board the vehicle. A determination unit determines priorities of the pieces of information acquired by the acquisition unit on the basis of a service or the like used by the driver among services or the likes provided using information accumulated in a server device. A selection unit selects a piece of information to be transmitted to the server device from among the pieces of information acquired by the acquisition unit on the basis of the priorities determined by the determination unit. A communication unit transmits the piece of information selected by the selection unit to the server device.

Abstract: A hybrid vehicle includes an engine, a motor, and a controller. The controller is configured to control the engine and the motor. The controller is configured to, when the engine is operated under load at the time when the vehicle slows down and stops in an autonomous driving mode in which the vehicle runs without driver's operation, set a controlling lower limit rotation speed of the engine to a maximum rotation speed out of a plurality of candidate rotation speeds and control the engine such that the engine is operated under load within a range higher than or equal to the controlling lower limit rotation speed.

Abstract: A control device for a vehicular automatic transmission is provided which can preferably execute backpressure control of accumulators and torque-up control so as to minimize the occurrence of interference between learning on these controls during a gearshift operation. With the control device for the vehicular automatic transmission including the accumulators (104, 106 and 108) operative to control a hydraulic pressure supplied to second and third clutches (C2 and C3) and a third brake (B3), the backpressure control is executed for controlling a backpressure of the accumulators (104, 106 and 108) during the gearshift operation while the torque-up control is executed for raising torque output from an engine (12). Completion of learning on the backpressure control is determined when no completion of learning on the backpressure control is determined, learning on the backpressure control is executed with no execution of the torque-up control.

Abstract: A filter material comprises a cellulose acetate fiber tow containing 5-50% by weight of a water soluble material and/or a water dispersible material which are soluble in a solvent which dissolves cellulose acetate and which are not compatible with cellulose acetate. Due to the inclusion of the above-mentioned water soluble material and/or water dispersible material in the cellulose acetate fiber, in the presence of moisture, the fiber surface becomes porous by the elution of this water soluble material and/or water dispersible material from the fiber, and the surface area of the fiber is increased. Consequently, the shape of the cellulose acetate fiber tow is easily broken down, and the decomposability of the fiber by microorganisms and the like is increased. When a cigarette filter is made using this type of filter material, a cigarette filter is obtained which has easy decomposability in the natural environment and particularly in water, in atmospheres which contain large amounts of moisture, and the like.
