A semiconductor device of the present invention includes a first main electrode and a second main electrode respectively disposed on a first main surface and a second main surface of a semiconductor substrate, a protective film disposed on an edge part of the first main electrode; and a first metal film disposed in a region enclosed by the protective film on the first main electrode. The first metal film has a film thickness at a central portion larger than that at a part in contact with the protective film, and has irregularities on a surface thereof.

Semiconductor device and manufacturing method of semiconductor device

An audiometer is provided which has: a main body section; and multiple sets of a headphone section and a response operation section, wherein the main body section performs wireless communication with the headphone section and performs wireless communication with the response operation section independently of the wireless communication with the headphone section, thereby supplying a test sound output command to the headphone section to cause the headphone section to output the test sound and receiving information on operation by a subject from the response operation section, and performs the wireless communication with the headphone section and the response operation section of each set by a time-division multiplexing system.

Audiometer

An earphone for an audiometer is provided, which includes a right earphone portion, a left earphone portion, a right light-emitter corresponding to the right earphone portion, a left light-emitter corresponding to the left earphone portion, and a controller, wherein the controller selects any one of the right earphone portion and the left earphone portion as an earphone portion for presenting a test sound, and causes the light-emitter corresponding to the selected earphone portion to emit light in a mode in accordance with the test sound.

A prediction value calculator calculates a prediction value of an electricity fee based on the amount of electric power supplied from a commercial electric power source to electric equipment within an electricity fee calculation period. A selector selects, as a first-stage control, either one control of an electric power saving control for the electric equipment and a charge-discharge control in which the electric power supplied from the commercial electric power source is stored in a storage battery in a first time slot and the electric power stored in the storage battery is supplied to the electric equipment in a second time slot in which the unit cost of the electric power supplied from the commercial electric power source is greater than that in the first time slot. A controller executes the first-stage control selected by the selector when the prediction value calculated by the prediction value calculator is greater than a targeted value of the electricity fee.

Control device, control system, control method and program

Upon receiving a command signal transmitted from a remote controller (), based on contents of the received command signal, a setter of an electrical apparatus sets a time interval for prohibition of operation from an operation terminal. During the time interval set by the setter, an operation controller of the electrical apparatus does not control based on the received command signal, even if a command signal transmitted from the operation terminal is received via a HEMS controller.

A standardized information acquirer acquires standardized information from an electric device. A standardized telegraphic message sender sends a standardized telegraphic message including the standardized information to a communication device. An unstandardized information acquirer acquires unstandardized information from the electric device. A standardized telegraphic message receiver receives the standardized telegraphic message including the standardized information. An electric device determiner determines whether the electric device meets a specific condition based on the standardized information included in the received standardized telegraphic message. When the electric device is determined to meet the specific condition, an unstandardized telegraphic message sender sends the unstandardized telegraphic message including the unstandardized information. An unstandardized telegraphic message receiver receives the unstandardized telegraphic message including the unstandardized information.

Communication system, communication device, communication adapter, communication method, and program

A control apparatus is configured to control a control target device among load devices for which power supply from an electricity storage apparatus is controlled based on total power consumption of the load devices. The control apparatus includes a power monitor and a device controller. The power monitor is configured to acquire a value of the total power consumption of the load devices. The device controller is configured to control the control target device to change the power consumption of the control target device so that the value of the total power consumption changes to a value having a level where the electricity storage apparatus supplies the power to the load devices when the value of the total power consumption acquired by the power monitor is at a level where the power is not supplied from the electricity storage apparatus to the electrical devices.

Control apparatus, control system, control method, and recording medium for controlling devices to charge or discharge electricity storage apparatus

An acquirer acquires information concerning an energy management system for controlling a plurality of apparatuses installed in a dwelling. A display displays, in a first display region, the information acquired by the acquirer, and displays, in a second display region, a layout diagram in which images indicating the apparatuses are arranged at positions corresponding to installation locations of the apparatuses in the dwelling. Upon a determination that the information displayed in the first display region includes information concerning a specific apparatus among the plurality of apparatuses, the display displays with relative emphasis an image indicating the specific apparatus in the second display region.

The present invention relates to a method and apparatus for removing and recovering copper by treating an acidic waste liquid containing copper ions such as an etching waste liquid resulting from etching a copper printed board in an etching solution of cupric chloride and a waste liquid after renewing a plating bath liquid in producing electrolytic copper foil. In particular, a copper recovering method of recovering copper from a copper-containing acidic waste liquid includes adding a liquid mixture of a copper-containing acidic waste liquid and an oxidizing agent to an alkaline agent solution while a pH of the alkaline agent solution to which the liquid mixture has been added is being controlled so as never to decrease to seven or lower, and by obtaining a solid material whose main component is copper oxide.
