Abstract: A processing apparatus obtains sales information from a control box of the vending machine which is connected to the computer via an interface compliant with an RS-232C standard, generates data of a screen corresponding to a specific path and including the sales information of the vending machine on a basis of the obtained sales information and transmits the data to a terminal, when having received a display request including a designation of the specific path, from the terminal.

Abstract: The present invention aims to provide an information reproducing/recording device capable of enhancing the reliability of a focus jump.

Abstract: An automatic irrigation system having a simplified structure can intermittently supply water (and liquid fertilizer) required by farmer products under water saving conditions depending on the weather condition of the day independent of the size of an irrigation area. Water from a water source is pumped by a motor pump driven with electric power generated by a solar panel and stored in a storage tank. When a predetermined amount of water is stored in the tank, a water draining device continuously drains the stored water. This cycle is repeated in proportion to an amount of solar radiation incident on the solar panel. The water is then guided to the irrigation area with a tube irrigation system.

Abstract: Disclosed is an automatic irrigation system of the simplified structure which can intermittently supply water (and liquid fertilizer) required by farmer products under the water saving condition depending on the weather condition of the day (an amount of solar beam in a day) without relation to the size of irrigation area. In this automatic irrigation system, water of the water source is pumped up with a motor pump which is driven with electric power generated by a solar panel and is then stored in a reserving tank. When a predetermined amount of water is stored in the reserving tank, a water draining means continuously drains all the water in the reserving tank. This cycle is repeated in proportion to an amount of solar beam in a day. The water is then guided to the irrigation area with a tube irrigation system. An amount of water to be irrigated is proportional to that of solar beam in a day. A liquid fertilizer mixing device is also used simultaneously when it is required.
