Abstract: PURPOSE:To control the flow of air in an agricultural house and ideally perform the control of temperature in the house by attaching a string to a fixed rotational shaft and a transfer rotational shaft in a tangential type and further fixing one end of a soft thin filmy on the transfer rotation shaft. CONSTITUTION:The left half of a house is covered with a sheet 8 and the right half is covered with a sheet 10. At the position of a shaft Y the left end U of the sheet 10 is placed the sheet 8 to close the ridge of the house with the sheets 8 and 10. When the shaft Y is rotated counter clock wise toward the arrow, the shaft Y is left transferred and the sheet 8 and the string 4 and wound up and the string 4 is simultaneously unwound from the shaft X. The sheet on the ridge is opened only a distance of the counter clock wise rotation of the shaft Y, and when the shaft Y is transferred to a position of Z, the sheet of the ridge is opened for only a distance of U-V. In order to close the sheets of the ridge the shaft X is rotated clock wise when the string is an outer tangential type or the shaft X is rotated counter clock wise when the shaft X is an inner tangential type, thereby pulling the string of the shaft Z to rotate clock wise and pull the shaft Z in the direction. At the position of the shaft Y the sheet of the ridge is perfectly closed. The degree of closing or opening of the sheet can be controlled by suitably selecting the position of the shaft Z.

CONSTITUTION:If a dielectric material 2 is deposited by evaporation on a substrate 1 at an incident angle theta thereto, the vapor-deposition film 3 formed in such a way has the refractive index larger in an X direction than in a Y direction. The difference in the optical path between the slowest oscillation direction (X) and fastest oscillation direction (Y) when light passes the film 3 in a Z direction is referred to as ''retardation''. A vapor deposition device 11 is constituted of a vacuum bell-jar 12, a vapor source 13 and a substrate mounting part 14. The part 14 has a substrate 15 of glass plate or the like to be subjected to vapor deposition. The inside of the bell-jar 12 is kept at <=10<-5>mm.Hg degree of vacuum. The substrate 15 is so disposed that its surface faces at the angle theta to the source 13. If the vapor-depositing material is evaporated, the vapor ascends straightly and sticks on the surface of the substrate from the angle theta to the vertical direction of the surface, that is, the incident angle theta for vapor deposition.
