Abstract: A head-mounted display device includes an image display unit (300a, 300b) configured to emit image light, a light guide member (100a, 100b) configured to guide the image light and emit the image light to eyes of a wearer who wears the head-mounted display device, and a relay optical system (201a, 201b) arranged between the image display unit and the light guide member, and configured to relay the image light from the image display unit to the light guide member, and form an intermediate image at least once before the image light enters the light guide member.

Abstract: An image pickup module includes: a lens unit including a first principal surface and a second principal surface; an image pickup unit including a third principal surface and a fourth principal surface on which an external electrode is disposed; a wiring board including a hole and a bonding electrode disposed on a bottom surface of the hole; a solder that bonds the bonding electrode and the external electrode; a rigid member that defines a spacing between the fourth principal surface and the bottom surface; and a second resin disposed between the fourth principal surface and the bottom surface.

Abstract: When there is a restart request to an engine, an electronic control unit controls a wastegate valve to a fully open position on condition that a speed of a vehicle is less than a threshold. When the vehicle speed is not less than the threshold, the electronic control unit restarts the engine and controls the wastegate valve in the closing direction until a desired torque is generated.

Abstract: A compressor wheel includes a shaft portion, which extends in the rotation axis direction of the compressor wheel. Blades protrude in the radial direction from the shaft portion. The blades are spaced apart from each other in the circumferential direction of the compressor wheel. The compressor housing has an accommodation space that accommodates the compressor wheel. The compressor housing also has an introduction passage defined therein. The introduction passage is connected to the accommodation space from the intake side and introduces intake air into the accommodation space. Plate-shaped guide vanes protrude from the inner wall surface of the introduction passage. The guide vanes are spaced apart from each other in the circumferential direction of the introduction passage. The number of the guide vanes is the smallest odd number that is greater than the number of the blades.
