Abstract: An inertial sensor includes a lower substrate and an upper substrate. The upper substrate includes a micro oscillator, electrodes and a pad, which are independent of each other. The micro oscillator includes a curved surface portion, a joint portion recessed inward from an apex of the curved surface portion and joined to a support portion of the lower substrate, a rim at an end of the curved surface portion and a conductive film covering the micro oscillator. The curved surface portion is in an aerial state. The rim is made of the same material as the electrodes, located on a virtual flat plane formed by the electrodes, and apart from and surrounded by the electrodes. A portion of the conductive film that covers the joint portion is electrically bonded to a lower metal film covering the support portion.

Abstract: A wafer processing apparatus is configured to process a wafer by supplying mist to a surface of the wafer. The wafer processing apparatus includes a furnace in which the wafer is disposed, a gas supplying device configured to supply gas into the furnace, a mist supplying device configured to supply the mist into the furnace, and a controller. The controller is configured to execute a processing step by controlling the gas supplying device and the mist supplying device to supply the gas and the mist into the furnace, respectively. The controller is further configured to control the mist supplying device to stop supplying the mist into the furnace while controlling the gas supplying device to keep supplying the gas into the furnace when the processing step ends.

Abstract: In a power conversion apparatus, first to xth converters are connected in parallel to each other. A control unit outputs, based on command information related to an output of the power conversion apparatus, control information. A pulse generator selects, based on the control information, a number n of converters from the first to xth converters, n being an integer more than or equal to 2 and smaller than x. The number n is defined as a multiply-driven number n. The pulse generator generates, based on the control information, at least one multiple drive-pulse train that comprises n drive pulses for multiply driving the n selected converters. A variable determiner changes the multiply-driven number n.
