Title: Static charge recording card
Inventor: MATSUO MAKOTO
IPC: G11B9/08
Filed: 1988-05-24
Abstract: PURPOSE:To accumulate data of high quality and high resolution, and to preserve said data as electrostatic latent images for a long period, by laminating onto a card base material a static charge recording body obtained through the lamination of an insulating layer on electrodes, in a manner that said insulating layer becomes the upper surface of said recording body. CONSTITUTION:An insulating layer 11 is laminated on a static charge recording electrode 13 thereby to form a static charge recording body 3 on a card base material. When the static charge recording body 3 is used together with a photoreceptor, data is recorded on the surface of the insulating layer 11 or thereinside as a distribution of static charges. The static charge recording electrodes 13 are formed wholly in the interval between a static charge recording body support 15 and the insulating layer 11 or, on the support 15 in accordance with the forming pattern of the insulating layer. The material of the electrodes is not limited if only the specific resistance thereof is not higher than 10<6>OMEGA.cm. Since the insulating layer 11 laminated on the electrodes 13 records data on the surface thereof or thereinside in the form of a distribution of static charges, a high insulative property is required in order to restrict the move of the charges, and therefore the specific resistance of the insulating layer should be not lower than 10<14>OMEGA.cm.

Title: Air blow direction changer
Inventor: SUGAWARA NORIO
IPC: F24F13/22
Filed: 1977-10-24
Abstract: PURPOSE:To stabilize the deviation of a stream caused by Coanda effect and to prevent the dew condensation on a guide wall by forming a hygroscopic heat-insulating layer on the guide wall of the blow off part of an air conditioner. CONSTITUTION:A conditioned air stream turned downward by a horizontal blade 12 in a blow off part 7 is sent near a guide wall 13 and flows along the surface of the guide wall 13. In this case, since the guide wall 13 is curved to have the greater slanting angle toward the downstream, the air stream is stuck to this curved guide wall 13 by Coanda effect to be given a greater deviation along the guide wall 13. At this stage, as the guide wall 13 is given a smooth hygroscopic heat-insulating layer on its surface by the spray of fine fibres, the air stream can be given a stable deviation by the sticking to the guide wall, and condensation dews are absorbed without the fear of dripping.
