Title: Image display device
Inventor: NAKAMURA HOCHI
IPC: G02B5/30
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a luminous type image display device of low external light reflection and high contrast. SOLUTION: A reflection polarization layer 20 which separates the linearly polarized light of incident light, allows the transmission of the light (for example, P wave) of one polarization direction and reflects the light (S wave) of the polarization direction perpendicular thereto is disposed on the outside surface of a glass plate 1 on the display surface side. A polarization light 21, which separates the linearly polarized light of the incident light, allows the transmission of the light of the one polarization direction and absorbs the light of the polarization direction perpendicular thereto, is disposed on the display surface side of the reflection polarization layer 20 in such a manner that the light (here, P wave) of the polarization direction where the light transmits the reflection polarization layer 20 is transmitted.  The diffused light entering from the outside is separated to the P wave and the S wave at the time of the transmission through the polarization layer 21. The S wave is absorbed and the P wave is transmitted. Further, the P wave transmits the reflection polarization layer 20 as well and is reflected by a phosphor 8 toward the display side. As a result, the reflection of the external light is reduced to about half the reflection heretofore. The emitted light from the phosphor 8 is nearly completely converted to the P wave which is emitted to the display surface side.

Title: Surface acoustic wave filter
Inventor: KITANO TOSHIHIKO
IPC: H03H3/08
Filed: 1982-03-11
Abstract: PURPOSE:To obtain a sharp pass band and to increase the specific band, by giving a wider range to the amplitude frequency characteristics of input and output converters than those decided by a reflective grating. CONSTITUTION:Input and output converters 12 and 15 made of roller-screen type electrodes and reflective gratings 13 and 14 are provided on a piezoelectric substrate 11. The sharp band pass characteristics are realized by the gratings 13 and 14, and the frequency bands of the input and output converters are set wider than those of the gratings. The converters 12 and 15 are made of dispersing roller-screen electrodes with which the space between electrode fingers changes gradually to the propagating direction of a surface acoustic wave. In this case, those roller-screen type electrodes are positioned to move in parallel to each other. Therefore no difference is produced between distance of propagation due to the frequency even at the input and output converter parts to obtain the non- dispersing properties. A reduction can be avoided for the number of electrode fingers as long as the prescribed length is secured for the electrode and even though a wide band is needed for the dispersing roller-screen type electrode.

Title: Formation of deposited film
Inventor: ISHIHARA SHUNICHI
IPC: G03G5/08
Filed: 1985-02-27
Abstract: PURPOSE:To facilitate the increase in area of the film, improvement in productivity, and mass productivity, while contriving the improvement in film properties, film-forming speed, and reproducibility, and the uniformity in film quality, by a method wherein an active species A produced by decomposing a compound containing silicon and halogen and an active species B produced out of a nitrogen-containing compound are separately introduced, which are then made to chemically react by the action of discharge energy, thus forming a deposited film. CONSTITUTION:A discharge energy such as plasma is used as the energy to excite and make react the material for forming deposited films. Under the coexistence of an active seed A produced by decomposing the compound containing silicon and halogen and an active species B produced out of the film-forming oxygen-containing compound, the chemical interaction by these species is caused by making discharge energy act on them or promoted and amplified; therefore, film formation is enabled by lower discharge energy than conventional. The formed deposited film very hardly receives adverse effects such as etching or another action, e.g. abnormal discharge.
