A load leveling system and a method for a power system are capable of attaining load leveling in a distribution substation unit. The load leveling system is for a power system with a controller having a major customer and lower transforming apparatus, and with a customer connected to the lower transforming apparatus via a low-voltage line. The system also has a communication unit between the customer and its own system, and control use time zones of devices within the customer, as well as an electric demand prediction unit, and a first load leveling processing unit. By employing such a system, it becomes possible to provide a load leveling system for a power system that is capable of realizing load leveling of both a distribution substation unit and a pole transformer unit.

An energy management system includes an equipment data management unit which manages charging/discharging loss of a battery and heat radiation loss of an electric water heater, and causes a control unit to perform control to give priority based on the comparison to the energy storage facility more reducing loss and store energy. The energy management system includes a system operation calculation unit which predicts voltage distribution of the next day of a distribution system or demand-and-supply balance amount of the entire system by state monitoring data of a power system, calculates a demand amount increasing target value necessary for avoiding a photovoltaic power generation amount suppression on a consumer end by the voltage distribution of the next day of the distribution system or the demand-and-supply balance amount, and controls the energy storage facilities so as to satisfy the demand amount increasing target value on the consumer end.

An optical disk apparatus driving an optical disk includes a tilt-angle adjusting unit configured to adjust a tilt angle indicating the tilt of an optical axis of laser light emitted from a pickup to detect an optimal tilt angle at which a traverse signal has the maximum amplitude and a storing unit configured to store information about the optimal tilt angle. When the optical disk has multiple recording layers on one side, the tilt-angle adjusting unit adjusts the tilt angle with respect to each of the multiple recording layers to detect the optimal tilt angle and the storing unit stores information about the optimal tilt angle with respect to each of the multiple recording layers. The tilt angle with respect to each of the multiple recording layers is controlled in accordance with the information about the optimal tilt angle with respect to each of the multiple recording layers.

摘要:
There is provided a liquid supply method in which, when preparing a solution that can be used as washing water and the like by supplying a minute amount of chemicals and the like to ultrapure water, the amount of supply solution that is supplied can be accurately determined. In this liquid supply method, a solution is prepared by supplying a supply liquid to a primary fluid that is circulating in a primary fluid circulation tube (2). This liquid supply method uses a liquid supply apparatus (1) that includes: a supply section (3) that delivers the supply liquid; and a supply liquid circulation tube (4) that causes the supply liquid to flow from the supply section (3) to the primary fluid circulation tube (2), the internal diameter of the supply liquid circulation tube (4) being between 0.01 and 1 mm. When the supply solution is supplied from the supply section (3) to the primary fluid circulation tube (2) via the supply liquid circulation tube (4), a pressure P1 of the supply liquid in the supply section (3) and a pressure P2 of the primary fluid in the primary fluid circulation tube satisfy the formula P1−P2>0.

An operation support system is arranged to effectively provide an operator of an energy supply facility for supplying a plurality of energies in different forms with a hint of an operating method in which energy safety supply and operation cost reduction are both realized. The operation support system takes the steps of deriving demand prediction upper limit value and lower value for each energy form based on recorded demand data; deriving target operation pattern upper and lower limit values of each energy supply device based on the demand prediction upper and lower values; and displaying the target operation pattern upper and lower limit values.
