Abstract: The present invention prevents a defective display attributed to a non-uniform gap between a display element and a backlight which is caused by a phenomenon that an inner wall of a mold casing is shaved off by an end periphery of the display element and a shaved-off debris remains between the casing and the display element. Guide projections are integrally formed on an inner wall of a picture-frame-like portion of the mold casing and, at the same time, a gap which accommodates the shaved-off debris is formed between the guide projection and a bottom portion of the mold casing.

Abstract: To provide a soil characteristics survey device capable of efficiently acquiring high precision data information about the distribution of soil characteristics in an agricultural field, and managing the data information collectively. The soil characteristics survey device is composed of a pedestal connected to the rear of the tractor, a control unit (a computer) mounted on the pedestal, and a soil excavating unit attached below the rear end of the pedestal. While being towed by a vehicle 2 such as a tractor, the device surveys in real time the distribution of soil characteristics in a given agricultural field. At the top of the control unit is attached a GPS antenna. The soil excavating unit 50 is composed of a shank 51 connected to the bottom of the pedestal and a sensing unit which is fixed so the bottom of the shank 51 and advance in the soil approximately parallel to the ground at a predetermined depth.

Abstract: A buried gate electrode of a buried MOS transistor formed within a trench in an active region wherein a gate oxide film and a gate electrode are buried in the trench, and a lower electrode of a PIP capacitor formed on a device isolation, are simultaneously formed by etching of polycrystalline silicon formed on an entire surface of the structure.
