摘要:
An electric-power-generation level predicting apparatus 1 includes a memory unit 20 that stores, as past data relating to a past electric power generation level of an electric power generator, past data containing information at multiple time points in each day, and an predicted-value calculating unit 13 that calculates, as time-series data containing an occurrence probability, an predicted value of the past data relating to an electric power generation level of the electric power generator based on a statistical correlation between different times in the past data or a statistical correlation between locations of the different electric power generators. The predicted-value calculating unit 13 includes a variance-covariance-matrix generator unit 131 that generates a variance-covariance matrix based on the past data, and a random-number generator unit 132 that generates a random number following the probability distribution based on the variance-covariance matrix.

A current detection unit detects an electric current caused by superimposing a direct current from a direct-current power source on an alternating current from an alternating-current power source and supplied through a brush to a direct-current motor. An extracting unit extracts an alternating-current component of the detected electric current. An angle detection unit detects a rotation angle of the motor according to the extracted alternating-current component. A direction detection unit detects a rotative direction of the motor according to a change pattern of the extracted alternating-current component. A core of the motor has slots each defined between adjacent two of teeth. The slots respectively accommodate phase coils respectively wound around the teeth. Turns of the phase coils are different from each other.

A through portion is formed on a semiconductor substrate. Into the semiconductor substrate, a first ion implantation is performed via the through portion. The through portion is at least partially removed in the thickness direction from a region of at least a portion of the through portion when viewed in a plan view. A second ion implantation is performed into the semiconductor substrate at the region of at least the portion thereof. An implantation energy for the first ion implantation is equal to an implantation energy for the second ion implantation.

Disclosed herewith is a terminal for receiving data distributed from a host computer. The terminal includes a database for storing data distributed from the host computer and a schedule manager for managing the schedule of the terminal. Upon receiving an update request for the data stored in the database, the terminal extracts a time band in which the usage frequency of the terminal is kept low as an updatable time through the schedule manager and sends an update request to the host computer in response to the received request. The terminal calculates a processing time required to update object data, as well as a value denoting the usefulness of the object data according to the update information received from the host computer and including the object data, then decides a processing order for the object data according to the processing time and the usefulness value calculated respectively for the object data, thereby updating the data stored in the database according to the decided processing order. Useful data is updated preferentially in the time band in which the usage frequency of the terminal is low.
