摘要： A relay server computer adds control code to background contents to generate web data for display engagement, and sends the generated web data to every client computer. The control code becomes a controller by executed on the client. When an object such as image is pasted on the background contents displayed in an engaged fashion, the controller detects the event occurred by pasting, and sends the information indicating the event to the other clients via relay server. Consequently, the screen with the object being pasted is displayed in an engaged fashion among all clients. The object can be moved, modified, or deleted.

摘要： Three retardation compensators are provided for compensating the retardation of liquid crystal devices for red, green and blue light, respectively. Each of the retardation compensators is composed of plural high and low refractive index thin film layers alternately layered on a substrate. Because of the difference in the wavelength dependences of the liquid crystal device and the retardation compensator, the retardation R2 of the retardation compensator becomes much larger than the retardation R1 of the liquid crystal device in short wavelength region of the visible band. In order to match the retardation, the thickness of the retardation compensator for blue light is smaller than those for red and green light.

摘要： Manila grass (also South Japanese grass; Zoysia matrella L.) usually completely withers at the leaf part in winter in an area where frost occurs. The present variety of Manila grass is characterized by the ability to maintain green leaves (evergreen) in a whole year, a trait which has not been observed in other Manila grass varieties.The general characteristics of the present variety include somewhat straight grasses, slender leaf blades, and vividly green leaves, as well as dense greens which can be maintained in all seasons. The variety is somewhat resistant to turfgrass rust disease and is also resistant to usual pests, thereby reducing the cost of pesticides. In addition, the frequency of sprinkling, fertilization, and trimming can be reduced, so that labor can be saved in cultivating the variety.
