Title: Optical prism
Inventor: MUROTA MASAO
IPC: G02B5/04
Filed: 1982-10-22
Abstract: PURPOSE:To polarize light by 90 deg. while holding reflection factors to S polarized light and P polarized light equal to each other by cementing surfaces of a 45 deg. and a right-angled prism which contain one short side, and making light incident perpendicularly to an uncemented surface of one prism which contains the short side and projecting the light from the uncemented surface of the other prism which contains the short side at right angles. CONSTITUTION:The short-side surfaces of the 45 deg. and right-angled prisms 1 and 2 which have length (a) and thickness b=a are cemented. In this constitution, when light O is incident to the surface A of the prism 1 which contains the short side at right angles, it is reflected totally twice in the prisms 1 and 2 and projected at right angles to the surface B of the prism 2 which contains the short side. In this case, the reflection factor of the prism 1 to a P wave is equal to that of the prism 2 to an S wave and the reflection factor of the prism 2 to the P wave is equal to that of the prism 1 to the S wave as shown in a figure wherein two lateral axes show the intensity of light beams of the P wave and S wave, so the reflection factors to the P wave and S wave when the prisms 1 and 2 are combined together are equal to each other.

Title: Modulation system
Inventor: FUJINO TADASHI
IPC: H04L27/18
Filed: 1986-08-06
Abstract: PURPOSE:To reduce a code error rate by shifting even number-th transmission phase for a prescribed amount so as to make the Euclid distance longest for all erroneous paths. CONSTITUTION:In an n-phase PSK modulation system, the even number-th transmission phases among the n-pieces of ones are shifted for prescribed amount so as to make the Euclid distance longest for all the erroneous paths. For instance, of an eight-phase PSK modulation system whose transmital phases are as shown in the figure, using Ungerbeg code whose coding ratio is 2/3 and constrained length is; theta=4, such phases as (n) is an even number are left as they are, but the phases whose (n) are odd number(even number-th phase), are phase-shifted for an angle of theta=8.13 degrees or a value approximating this value. By making the intervals between the transmission phases irregular, the free Euclid distance dt becomes longer, and coding error rate can be lowered.

Filed: 1981-11-19
Abstract: PURPOSE:To prolong filtering life, in an asymmetric membrane for filtration, by enlarging the pore size of the fine pore of a nonwoven fabric used in a support from the front surface toward the back surface thereof to prevent the clogging thereof. CONSTITUTION:A nonwoven fabric of which the pore size is continuously or discontinuously enlarged from the front surface to the back surface thereof in a thickness direction such as ones integrally formed by laying staple fibers in a multilayer form such that the average length thereof becomes longer (or shorter) in a thickness direction or one integrally formed by laying staple fibers in a multilayer form such that the fiber diameters thereof becomes thicker (or finer) in the thickness direction is impregnated and coated with a solution of a thermoplastic resin and thus treated nonwoven fabric is dried to obtain an asymmetric membrane. About this membrane, because particles generating clogging during filtration are stepwise replenished in the thickness direction, the abrupt reduction in a filtering speed is not generated. Therefore, filtering life is enhanced to a large extent and three times or more of a total filtering amount can be attained as compared to a conventional membrane using a known nonwoven fabric.
