Abstract: An aerial vehicle safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a hole through which the piston member protrudes outward at time of operation, a push-up member that is pushed up in one direction by the piston member, an expandable object that is pushed up while being supported by the push-up member, a gas generator as a power source that moves the piston member in the cylinder, and a first member and a second member that serve as a cylindrical container that accommodates the piston member, the cylinder, the push-up member, the expandable object, and the gas generator. The expandable object is stored in the container so as to form a plurality of layers in a radial direction.

Abstract: In a door striker attaching structure, a door striker includes a rod and a base plate, in which the base plate includes rod support portions to which the rod is connected, and a pair of fastening portions through which the base plate is fastened to a vehicle body of a utility vehicle. The vehicle body is provided with fastening holes to which the fastening portions are fastened, and each of the fastening holes is an elongated hole having two central portions. The door striker is symmetric with respect to a first center line that connects centers of the fastening portions, and by inverting the door striker along the first center line, a second center line that connects centers of the rod support portions is biased in a direction along the first center line by a distance equal to a central distance between the central portions of the fastening holes.

Abstract: A utility vehicle includes a vehicle body frame, a hinge base attached to the vehicle body frame, a door provided to be openable and closable in a vehicle width direction with respect to the vehicle body frame, a hinge bracket attached to the door, and an intermediate bracket that is pivotably attached to the hinge base and to which the hinge bracket is attached. The hinge bracket is configured so that a position thereof with respect to the intermediate bracket can be adjusted, and thereby the door is configured to be adjustable in a vertical position.

Abstract: A virtual image presentation system includes: a projection unit that projects an image display light toward a virtual image presentation plane defined in a vehicle and presents a virtual image to a driver; an acquisition unit that acquires information for identifying a position of an object outside the vehicle; an identification unit that generates information for identifying relative positions of the object and the vehicle, based on the information acquired by the acquisition unit; and a virtual image position adjustment unit that adjusts a position to present the virtual image as viewed from the driver, based on the information generated by the identification unit.

Abstract: First position information indicating a position is acquired at a first time. Second position information indicating a position is acquired at a second time that is later than the first time. The first position information and the second position information are compared to determine whether or not a reproduction apparatus is moved. Information is stored in a recording medium in a first mode if it is determined that the reproduction apparatus is moved and the information is stored in the recording medium in a second mode different from the first mode if it is determined that the reproduction apparatus is not moved. The first mode is a reproduction mode having functions for use in reproduction more restricted than the second mode.

Abstract: Provided is a method for easily judging that a disc is an optical disc that conforms to the DVD Download standards, without generating malfunction. A Wobble signal is detected in a data zone (21) of an optical disc (YES in a step (S2)), CSS information is detected from a lead-in zone (20) of the optical disc (YES in step (S5)), and when attribute information, which is of the optical disc and recorded in the lead-in zone (20) of the optical disc, is further read and the disc is recognized as a DVD-ROM (YES in a step (S7)), the optical disc is judged as an optical disc that conforms to the DVD Download standards.

Abstract: Provided is a method for easily discriminating that a disc is a blank disc that conforms to the DVD Download standards. An optical disc device is provided with a first identifying means (4) which identifies disc information written in a lead-in zone of an optical disc (1); a second identifying means (4) which identifies that there is no data recorded in the data zone of the optical disc (1); and a discriminating means (5) which discriminates that the optical disc is a blank disc that conforms to the DVD Download standards, based on output from the first identifying means and output which is outputted from the second identifying means and indicating that there is no data recorded.

Abstract: An electric vacuum cleaner (1) of the invention is adapted for wipe off cleaning using a sheet wound about a rotary brush (25) incorporated in a suction device (10). In order to wind a sheet (50) around a periphery of the rotary brush (25), a brush motor (44) rotates the rotary brush (25) in a predetermined direction at a predetermined rotational speed. At the same time, suction force of an electric blower fan (42) is set to the lowest level. This achieves the following advantage in a case where a wet sheet is used as the sheet (50). During sheet winding, water and alcohol released from the wet sheet (50) can be prevented from being scattered on a surface (100) to be cleaned. Further, the released water and alcohol do not adversely affect the electric blower fan (42).
