Title: Cutting method for wafer of surface wave filter
Inventor: YAMADA TAKUJI
IPC: H03H3/08
Filed: 1978-08-28
Abstract: PURPOSE:To realize a good cutting method for the wafer of the surface wave filter by giving the first-half cutting with shaving the wafer formed to the electrode pattern from its main surface to the lower side and then giving the second cutting from the lower part up to the main surface, thus causing no cracking. CONSTITUTION:Main surface 22 where no electrode pattern is formed to wafer 21 made of the single crystal of LiNbO3 is stuck onto wafer feed table 24, thus fixing wafer 21. Then the wafer is carried in a fixed speed to be cut downward by cutter 25 rotating in a high speed from the main surface where the electrode pattern is formed and in the depth up to 30% of the total wafer thickness. After this, table 24 is carried backward to give an upward cut to the other main surface 22 of the rest of the wafer via cutter 25 and along the cutting groove put onto the wafer. Thus pellet 26 is obtained.

IPC: H04B10/079
Filed: 1989-04-24
Abstract: PURPOSE:To exactly detect and monitor a fault part in a transmission system by allowing a part of a received optical signal to branch, amplifying this branch optical signal, and thereafter, transmitting it to an optical transmission device. CONSTITUTION:An optical signal transmitted as a transmission medium through an optical fiber 2 is allowed to branch into two by an optical branching circuit 7. In these branch optical signals, one is received by an optical receiving circuit 3 as usual, and the other branch optical signal is made incident on a rare earth element addition optical fiber amplifying circuit 8 which can amplify and attenuate the optical signal in accordance with an incident state of an excitation light, and this amplified optical signal is looped back to an optical transmission device A. Accordingly, the optical signal can be looped back in a state that it remains light without converting it to an electric signal, and it does not depend on an operating state of the optical receiving circuit 3. In such a way, a fault part in a transmission system can be detected and monitored exactly.

Filed: 1985-05-16
Abstract: PURPOSE:To prevent the deterioration in properties of an electrode, by sealing the end of the electrode with a fluorine resin film under an atmosphere of inert gas while cooling the effective portion of the electrode with the gas. CONSTITUTION:Inert gas such as nitrogen gas is caused to flow in spaces among the frames 11, 12 of a jig and a hotpress 13 through the inert gas inlet holes 14, 16 and water outlet holes 15, 17 of the frames so that a fluorine resin film 10 is fuse-bonded on the end of an electrode plate while an effective electrode portion including a catalyst layer 4 is cooled under the atmosphere of the inert gas flowing in the spaces. Thus, the rise in the temperature of the effective electrode portion is suppressed and sealing work is performed under the inert gas. This results in preventing the sintering of a catalyst, the oxidation of a catalyst carrier or the enlargement of each fluorine particle of the effective electrode portion.

Title: Light transmission plate, polarizing light source and liquid crystal display device
Inventor: UMEMOTO SEIJI
IPC: G02F1/1335
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To efficiently emit light incident on the side surface of a light transmission plate from the upper surface thereof and to efficiently emit the light incident again through a circularly polarized light separating layer so as to improve light utilization efficiency by setting a phase difference by double refraction in a thickness direction to a specified value in the light transmission plate reflecting the light incident on the side surface by the lower surface and emitting it from the upper surface. SOLUTION: In this light transmission plate 1, the light incident on the side surface 14 is reflected by the lower surface 12 and emitted from the upper surface 11, and the phase difference by the double refraction in the thickness direction is set to 0-30nm, desirably, <=20nm. The smaller the phase difference by the double refraction in the thickness direction of the plate 1 is, such as 0-20mm, the more desirable result is obtained. In the case it is <=30nm, the circularly polarized light incident again through the circularly polarized light separating layer is guided to the lower surface 12 while keeping nearly equal circularly polarized light state without influence by the phase difference in substance. The return path light reflected by the lower surface 12 is also emitted while maintaining the circularly polarized state.  Therefore, the brightness of the display of a liquid crystal display device is improved.
