Abstract: A power control device for a hydrogen system according to the present embodiment is a power control device configured to control a supply of generated power generated by a renewable energy generation device, and includes an acquirer and a controller. The acquirer acquires information related to an amount of power sale in a predetermined period. The controller controls the power supplier of the renewable energy generation device to sell power from the generated power, such that the integrated value of the power sale in time series in a predetermined period becomes the power sale amount. The controller makes an average value of the power sale in a first period within the predetermined period larger than the average value of a second period within the predetermined period after the first period.

Abstract: A power prediction device according to the present embodiments includes an evaluation-value generator and a prediction circuit. The evaluation-value generator is configured to generate a time-series evaluation value based on a time-series error of weather-related forecast data. The prediction circuit is configured to, as for a time and an amount of power of demand response that changes a pattern of power consumption or power production, predict at least the time in accordance with the time-series evaluation value.

Abstract: According to one embodiment, one of two connectors, and a circuit board on which the other of the connectors is mounted are prepared. The one of the connectors has an engagement portion. The other of the connectors has an elastically deformable engagement detent. The engagement detent can go over the engagement portion and be engaged with the engagement portion. One of the connectors is fitted to the other of the connectors. A portion of the electric equipment is imaged by a camera. A piece of data which changes is measured from an obtained picture image. A deformation of the engagement detent occurs with going-up of the engagement detent onto the engagement portion. Whether or not the connectors are properly fitted is determined. Fitting of the connectors is performed again when it is determined that the connectors are not properly fitted.

Abstract: An airborne microbial measurement apparatus and a measurement method thereof are provided. An airborne microbial measurement apparatus according to an embodiment includes a discharge apparatus including a discharge electrode and a voltage supply unit applying a high voltage to the discharge electrode. A substrate is provided to a side of the discharge apparatus to collect an airborne microbe from air by a high voltage applied to the discharge electrode. A reagent injection apparatus supplies a dyeing reagent to the microbe collected on the substrate or a DNA of the microbe. A light emission measurement apparatus senses a quantity of light generated from the DNA to which the dyeing reagent is supplied. The discharge apparatus includes a controller controlling the voltage supply unit so that the voltage is applied to collect the airborne microbe or destroy an external wall of the collected airborne microbe.

Abstract: An exogenous substance transfer apparatus that introduces an exogenous substance into a small amount of cells by electrical action and a method for manufacturing exogenous substance-bearing cells at low cost are provided. In the introducing an exogenous substance like a gene into a cell, a cell suspension liquid that contains the cell and the exogenous substance is supplied to a container through an opening portion in an amount that is prepared such that a liquid droplet that is formed will not come into contact with a pair of electrodes simultaneously. The liquid droplet is formed in an oil stored in the container, without the cell suspension liquid mixing with the oil. When a direct current voltage is supplied to the electrodes from a power supply, the liquid droplet moves there-between, and the exogenous substance is introduced into the cell within the liquid droplet by electrical action.

Abstract: An exogenous substance transfer apparatus that introduces an exogenous substance into a small amount of cells efficiently and at low cost by electrical action and a method for manufacturing an exogenous substance-bearing cell that is able to manufacture many kinds of exogenous substance-bearing cells at low cost are provided. In the introducing of an exogenous substance such as a gene or the like into a cell, a cell suspension liquid that contains the cell and the exogenous substance is supplied to a container (2) through an opening portion (17). The cell suspension liquid is supplied to the container (2) in an amount that is prepared such that a liquid droplet (W) that is formed will not come into contact with a pair of electrodes (5a, 5b) at the same time. The liquid droplet (W) is formed in an oil (6) that is stored in the container (2), without the cell suspension liquid mixing with the oil (6). The liquid droplet (W) is disposed between the electrodes (5a, 5b).
