Abstract: A head-mounted display configured to enhance the ease of wearing work and the stability of wearing is provided. A wearing band has an extending section and a movable section that is movable relative to the extending section in the length direction of the wearing band. A locking mechanism is capable of switching the wearing band between an unlocked state in which the movements of the movable section in the extending direction in which the length of the wearing band is increased and in the retracting direction in which the length of the wearing band is decreased are allowed and a locked state in which the movement of the movable section in the extending direction is restricted. The movable section is urged at least in the retracting direction in an unlocked state.

Abstract: An auxiliary power supply device includes a parasitic diode forming a parallel circuit together with a second switching element and connected in a forward direction to a main power supply, and a parasitic diode forming a parallel circuit together with a fourth switching element and connected in a reverse direction to an auxiliary power supply. When a state parameter indicates that a reaction force that interferes with operation of an assist motor is applied, an electronic control unit turns ON a first switching element, turns OFF the second switching element, turns ON a third switching element, and turns OFF the fourth switching element. A regenerative current from the assist motor flows to the auxiliary power supply via an inverter, the third switching element, and the parasitic diode.

Abstract: A power source device includes a switching circuit configured to switch the power supply mode between a first power supply mode, in which power is supplied to a drive circuit for an electric motor by only a main power source, and a second power supply mode, in which power is supplied to the drive circuit utilizing both the main power source and an auxiliary power source. A control device includes: a determination unit that determines whether the operation state of the electric motor is a regeneration state or a power-running state; and a unit configured to limit power to be supplied to the drive circuit when the power supply mode is the second power supply mode and it is determined by the determination unit that the operation state of the electric motor is the regeneration state.

Abstract: An auxiliary power supply apparatus includes a first switching circuit and a second switching circuit. The first switching circuit is disposed between a charging circuit and positive terminals of a plurality of auxiliary power supplies. The first switching circuit is configured to perform switching between or among the auxiliary power supplies such that at least one of the auxiliary power supplies is connected to the charging circuit, and the other auxiliary power supply or supplies is or are connected to a power supply destination. The second switching circuit is configured to perform switching between a parallel connection state and a series connection state. In the parallel connection state, the auxiliary power supplies are connected in parallel between a main power supply and the first switching circuit. In the series connection state, the auxiliary power supplies are connected in series between the main power supply and the first switching circuit.

Abstract: In a high output voltage mode, switching elements in a charging circuit are set to OFF; a first switching element is set to ON; second and third switching elements are set to OFF; one switching element in a discharging circuit is set to ON; and another switching element in the discharging circuit is set to OFF. During a main power failure, one of the switching elements in the charging circuit is set to OFF; another of the switching elements in the charging circuit is set to ON; the first switching element is set to OFF; the second and third switching elements are set to ON; the one switching element in the discharging circuit is set to ON; and the other switching element in the discharging circuit is set to OFF.

Abstract: Aspects of the present disclosure includes a semiconductor structure and a method of forming. A plurality of fins on a semiconductor substrate and a plurality of dummy gates is formed. The plurality of dummy gates are oriented perpendicular to the plurality of fins. An amorphous silicon layer is formed directly on top of said plurality of dummy gates and on top of the plurality of fins. A first portion of the amorphous silicon layer between at least one pair of adjacent dummy gates of the plurality of dummy gates is removed to form an opening. A nitride layer is deposited in the opening to cover the plurality of fins. The rest of the amorphous silicon layer between other adjacent dummy gates is removed to expose the underneath plurality of fins. Source/drain regions are formed surrounding the exposed plurality of fins.
