Abstract: A frequency selective plate which is produced by coating an Ag layer dispersed with Ag particles on a transparent substrate. The Ag layer is formed by depositing an Ag continuous layer on the substrate and heating the Ag continuous layer to varying into Ag particles or by depositing an Ag continuous layer on the heated substrate. The frequency selective plate performs high transparency of radio waves and visible rays while sufficiently reflecting near-infrared rays of solar radiation.

Abstract: An arrangement for attaching a gearshift assembly for a motor vehicle is provided, wherein a shift lever device for performing a gearshift operation of a transmission of the vehicle is installed on an instrument panel, without causing variations in the position of installation of a shift lever. In the present arrangement, the shift lever device is positioned relative to the instrument panel by means of a guide pin, and a console panel is positioned relative to the instrument panel using positioning holes. Thus, the position of the console panel relative to the shift lever device is determined with high accuracy on the basis of the instrument panel, and the shift lever device is mounted on the instrument panel without causing a variation in the position of installation of the shift lever.

Abstract: A gearshift apparatus having a shift lever is constructed so that the transmission stage can be set or changed by manual operation when the shift lever is moved from a main gate for an automatic transmission mode to a manual gate for a manual transmission mode through a transit gate. The apparatus comprises a detent unit attached to the body of a vehicle. The unit contains a moving member for selection therein. The moving member moves integrally with the shift lever when the lever moves in the transit gate. When the lever moves in the main gate or the manual gate, the moving member never follows the motion of the lever. The detent unit is provided with a retaining mechanism for producing a retaining force for retaining the shift lever and a click feeling at either end of the transit gate as the lever moves along the transit gate. The shift lever has a simple construction, although it is provided with all necessary functions for the change between the automatic and manual transmission modes.
