Title: Superconducting paint
Inventor: SHIGA MASAAKI
IPC: H05K9/00
Filed: 1987-12-09
Abstract: PURPOSE:To reduce the number of components and assembly works required for countermeasure against electromagnetic interference by a method wherein superconductive substance is contained in paint applied to electronic components and electronic equipment. CONSTITUTION:The content of superconductive substance contained in paint is preferably not higher than 60vol.%. If the content exceeds 60vol.%, the coating characteristics of the paint are deteriorated and a satisfactory coating film can not be obtained. To the contrary, if the content is too low, the characteristics of the superconductive substance can not be exhibited. If the paint is applied to electronic components and electronic equipment, the electromagnetic wave suppressing performance of the superconductive substance is exhibited and electromagnetic interference inside and outside the electronic components and equipment can be avoided. For instance, the superconducting paint is applied to the inner surface of the housing 1 of a word- processor to form a coating film 6. The noise such as the electromagnetic wave emitted from a printed wiring board 2 is cut off by the coating film 6 and is not transmitted outside so that interference against the other equipment can be suppressed. Moreover, the external noise such as the electromagnetic wave can not reach inside so that the external electromagnetic interference can be efficiently avoided.

Title: Lenticular screen and stereoscopic display device using same
Inventor: YAMADA SENHIKO
IPC: G03B21/625
Filed: 1994-12-15
Abstract: PURPOSE: To converge the light beams from the left and right eyes only on a pixel to be naturally visualized by specifying the converging width of corresponding cylindrical lenses on both sides on a scattering surface. CONSTITUTION: The converging widths of corresponding cylindrical lenses 11, 12 on both sides on the scattering surface are made tot satisfy the following conditions: the converging width of the front lens 11 < the converging width of the rear lens 12 < P/2, the converging width of the front lens 11 + the converging width of the rear lens 12 ≈n P/2, where, P represents the pitch of cylindrical lens and the converging width of the front lens ≠ 0. Since the converging width of the lens 11 on the observation side is not just focused width but has some extent, the pixel to be observed (the converging width of the lens 12 on the projection side) does not contain the adjacent pixels against the movement of the view point. Since the converging width of the lens 12 is smaller than P/2, although a pixel forming part and a pixel non-forming part are included in a light converging part having some width on an observer's side at the same time, the pixel is visualized by the observer considering the ratio of both parts.

Title: Dehumidifier
Inventor: ANDO YUKIHIRO
IPC: F24F1/00
Filed: 1993-12-13
Abstract: PURPOSE:To reduce a leakage of moisture condensation water, and contribute to make a device smaller by providing a covering means which makes a water conducting means be exposed to the outside of a space to be dehumidified. CONSTITUTION:Moisture condensation water which is absorbed by a water absorbing sheet is carried to a connected area between water absorbing material (water conducting means) 6 and a heat radiating plate from the water absorbing sheet, by a capillary phenomenon, and evaporated by the heat of the heat radiating plate. By this method, the moisture condensation water is automatically discarded. At this time, if the outside of the space to be dehumidified is at a high temperature, by the reaction of the cover 7, the water absorbing material 6 is exposed to the outside, and moisture condensation water tried to leak out from the water absorbing material through the cover 7. For this reason, the moisture condensation water is evaporated from the water absorbing material 6 by utilizing the high temperature of the outside. Thus, at a high temperature wherein a humidity is apt to be high as well, the moisture condensation water is evaporated from the water absorbing material as well, and even if moisture condensation water exceeding the evaporation capability of the heat radiating plate generates, the possibility of a water leakage can be reduced. Also, when the outside is at a low temperature, the water absorbing material is not exposed by the reaction of the cover 7, and the moisture condensation water does not try to leak out.
