Title: Nitride semiconductor substrate
Inventor: TAKAMIZAWA SHOICHI
IPC: C30B29/38
Filed: 2019-03-13
Abstract: To solve such problems that, when a nitride semiconductor layer is epitaxially grown on a silicon single crystal substrate, a distortion is generated due to lattice irregularity and a difference between coefficients of thermal expansion, and a large warpage and a crack are generated to cause a harm in manufacture of a device, and that a nitride semiconductor having satisfactory crystallinity is not obtained.SOLUTION: A nitride semiconductor substrate that does not cause crack and large warpage and has satisfactory crystallinity is obtained by reducing thermal distortion which is generated due to the distortion generated due to lattice unevenness which is generated when the nitride semiconductor is epitaxially grown on the silicon single crystal substrate, and the difference between the coefficients of thermal expansion which is generated in a cooling process after the nitride semiconductor has been epitaxially grown, not only by a buffer layer on a side of the nitride semiconductor, but also by forming a misfit dislocation layer parallel to the surface on a side of the silicon single crystal substrate, and relaxing the distortion by the misfit dislocation of the silicon substrate.SELECTED DRAWING: Figure 1

IPC: B60W10/08
Filed: 2019-04-11
Abstract: To provide a hybrid vehicle capable of obtaining smooth acceleration while securing power performance (accelerating force) even if a small drive battery is adopted.SOLUTION: An ECU controls a PCU so that drive power required for a drive motor is supplied by referring to a maximum use power map.

Abstract: To provide a game machine allowing game balls to suitably enter a winning device having a movable member.SOLUTION: A ball passage part 3812 provided in an upstream side of a ball passage part 3814 is configured to be a ball passage inclined so as to rise toward a side leading to the ball passage part 3814. Accordingly, since a traveling speed of game balls moving in the ball passage part 3812 to a side leading to the ball passage part 3814 can be decelerated by the upward inclination, the traveling speed of game balls flowing down an area in which a lower-plate part 3852 functioning as a movable piece of an entry regulation mechanism 3454 in the ball passage part 3814 is disposed can be reduced as compared with a case in which a ball passage part inclined upward in an upstream side of the ball passage part 3814 does not exist, thus allowing game balls to suitably enter a right big winning device 3434.SELECTED DRAWING: Figure 33
