Abstract: A power converter includes first and second switching elements connected in series between first and second DC lines, third and fourth switching elements connected in series between the second DC line and a third DC line, an AC terminal, and a multilevel circuit. The multilevel circuit is connected between a first point of connection between the first and second switching elements and a second point of connection between the third and fourth switching elements, and the AC terminal. A filter includes a reactor having a first terminal connected to the AC terminal, and a capacitor connected between a second terminal of the reactor and the second DC line. The multilevel circuit mutually converts a first DC voltage received by the first point of connection and a third DC voltage received by the second point of connection, and a first AC voltage having at least five voltage values.

Abstract: This uninterruptible power supply device includes: a semiconductor switch that is connected between a bypass AC power supply and a load, is turned on when the bypass AC power supply is normal, and is turned off when the bypass AC power supply has a power failure; and an inverter that converts DC power supplied from an AC power supply or a battery into AC power and supplies the AC power to the load when the bypass AC power supply has a power failure, and supplies an assist current to the load if a load current is larger than a threshold current when the bypass AC power supply is normal, the assist current being a difference between the load current and the threshold current. Therefore, even if the load current is increased by load variation, the current flowing through the semiconductor switch can be maintained at the threshold current or lower.

Abstract: A platform of a gas turbine rotor blade according to one embodiment includes a groove portion recessed from an end surface on a trailing edge side toward a leading edge side. A bottom portion of the groove portion overlaps at least a blade-shaped portion when viewed from a radial direction.

Abstract: A liquid crystal layer is disposed on a second glass substrate side between a first glass substrate and a second glass substrate, a first insulating film and a second insulating film are formed in this order on a surface of the first glass substrate that is disposed on the liquid crystal layer side, the outer edge portion of the liquid crystal layer is surrounded by a sealing material, and a slit is formed in a part or the whole of the peripheral edge portion of the second insulating film disposed on a further inner side than a position at which the second insulating film overlaps the sealing material. In addition, a slit formed in a peripheral edge portion of the first insulating film that corresponds to the sealing material is filled with a gate insulating film having a higher barrier property for gas and/or liquid than the first insulating film.

Abstract: An image apparatus records images of a subject corresponding to a photo opportunity without intensifying complex operations after the imaging. When a SLOW button is depressed, a process is started in which frame image data that is obtained at an imaging frame rate is stored sequentially in a buffer memory. The frame image data is read out from the buffer memory at a display frame rate that is set in advance, and images are displayed on a display device based on this frame image data. When a shutter key is depressed, the frame image data read out from the buffer memory is recorded to storage memory.
