Abstract: PURPOSE:To prevent ply separation and corrosion by a method wherein a lami nated eaves gutter is formed by applying crosslinking vinyl chloride resin lamina tion to the interior and the exterior of a gutter-shaped core material. CONSTITUTION:Powdered vinyl chloride resin is stuck to reinforced fibers, and a prepreg sheet is formed by heating and pressurizing the same. Then the said sheet is formed into a gutter shape with a shaping machine, and thereby a gutter-shaped core material 2 is made. Then melted vinyl chloride resin containing reactive monomers is laminated to the interior and the exterior of the said gutter-shaped core material 2. After cooling and solidification are applied with a sizing machine, monomers contained in the laminated resin are highly polymerized by applying ionizing radiation thereto, and an eaves gutter 1 is formed by making the core material 2 covered with lamination of crosslinking vinyl chloride resin layer 3. Thereby an eaves gutter which is less liable to expand and shrink by heat and is excellent in heat resistivity and rigidity can be formed.

Title: Sea-water conveyance system laid on seabottom
Inventor: MANABE YASUHIRO
IPC: F04D13/04
Filed: 1987-04-22
Abstract: PURPOSE:To enable the water conveying pipe to be prevented from damage and carry away, and use corrosion-resisting materials by using a double-pipe as water conveying pipe for pumping up or transporting deep sea-water and using inner pipe of high specific gravity. CONSTITUTION:When any waves henerate on the sea surface, a wavepower pump 1 operates to supply pressurized water to an inner pipe 3 of a double-pipe, a pipe 6. The pressurized water in the inner pipe rotates a turbine 20 for driving a pump 4, and then is discharged from a hose 12. At this time, the rotation of the turbine 20 is transmitted to a water conveying impeller 21. In this operation, deep sea-water is transported through an outer pipe 2 of the double-pipe to a destination. The inner pipe 3 is laid in the outer pipe 2 of the double-pipe, and iron-cores 30, etc., are arranged so as to increase the specific gravity of the inner pipe. The double-pipe does not rise from the seabottom to the sea- surface by the weight of the iron-cores 30, and can therefore be laid without being carried away by external forces such as ocean current, tidal current, etc. As a result, the outer pipe 2 can be made of materials which resist corrosion, for example, polyethylene pipe, etc., and semipermanent water conveying pipe can be laid.

Title: Electromagnetic flowmeter
Inventor: MURASE NOBUYASU
IPC: G01F1/58
Filed: 1991-04-30
Abstract: PURPOSE:To omit a bobbin and to facilitate the determination of the positions of coils by intersecting and winding two exciting coils around a meter tube, and continuously forming one coil winding and the other coil. CONSTITUTION:A winding W is obliquely wound around a meter tube T, and an exciting coil C1 is formed. An exciting coil C2 is continuously wound with the winding W. The coil C2 is oblique in the reverse direction so as to cross the coil C1. Both coils C1 and C2 are arranged on the tube T in the X pattern. A current (i) flows through both coils in series. Since the numbers of the windings of both coils C1 and C2 are equal, the synthesized magnetic field is formed in the direction perpendicular to the axial line of the tube T. Thus, a flowmeter is operated. It is convenient when guide projections for winding are formed as a unitary body around the outer surface of the tube T. Since the coils are directly wound around the tube T, a bobbin is not required, and the accuracy of the size of the coil position becomes excellent.

Title: Optical transmission system
Inventor: MURAYAMA YUKIJI
IPC: H04B10/2507
Filed: 1994-05-12
Abstract: PURPOSE:To prevent an influence upon the fluctuation in output voltage of a reception circuit at the time of switching from the light emitting operation or a light emitting element to the light receiving operation in the optical transmission system where the one-element type optical transmission/reception equipment is used to transmit and receive a burst signal. CONSTITUTION:A guard time Tg of switching from the receiving operation to the transmitting operation is set for each destination terminal in accordance with a transmission distance L between terminals. When this transmission distance is shortest, a propagation delay time Td is set to 0, and the guard time Tg is so set that a half or a time Ta other than the transmission frame and the reception frame in one period of the burst signal is longer than the output fluctuation time for transmission/reception switching. A means which sets the time Tg to 0 in the case of the longest transmission distance between terminals is provided. Thus, an interval (switching time) Tc between the transmission frame and the reception frame can be longer, and thereby, the degradation in discrimination of the reception signal due to the fluctuation in output voltage of the reception circuit at the time of transmission/reception switching is eliminated. Since the guard time Tg is set to 0 in the case of the longest transmission distance, the transmission efficiency is improved.

IPC: H03C1/54
Filed: 1985-05-10
Abstract: PURPOSE:To obtain a modulator made into monolithic integration circuit with a small modulation phase deviation by increasing a power voltage of a basic multiplier of the post-stage more than a power voltage of an unbalance-balance conversion circuit of pre-stage. CONSTITUTION:An independent power is applied to unbalance-balance conversion circuits A, B of pre-stage and a basic multiplier section C of post-stage constituting a monolithic IC modulator and a higher voltage is applied to the basic multiplier section C of the post-stage. Thus, a deep bias voltage is given between the base and collector of transistors Q5-Q8 to decrease the change in the base-collector capacitor. Thus, the modulation phase deviation is reduced. Moreover, the phase modulation deviation is decreased further by increasing the power voltage of the basic multiplier section C.
