Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).

Abstract: A work vehicle steering control apparatus comprises a vehicle body (11), front wheels and rear wheels both of which can be steered respectively; a front-wheel steering cylinder (92) and a rear-wheel steering cylinder (94); a steering dial (72); a steering actuation controller (50); and a steering angle detector. The steering actuation controller (50) is configured in a manner such that when a steering operation is performed, and when the steering angles of one set of wheels are less than a predetermined angle (?1), the controller (50) controls the steering actuator to steer only the one set of wheels in response to the directional-change steering operation. When the steering angles of the one set of wheels are equal to or more than the predetermined angle, the controller (50) controls the steering actuator to steer the other set of wheels in a direction opposite to steering direction.

Abstract: A gettering site is formed on the backside of a wafer, contaminant impurities are trapped in the gettering site by heat treatment, a contaminated layer of the gettering site including the impurities is removed. The impurities are thus prevented from being freed from the gettering site into the wafer. A new gettering site is then formed on the backside of the wafer. Such a gettering operation has therefore a refresh function.
