IPC: H04B10/54
Filed: 1990-09-05
Abstract: PURPOSE:To expand furthermore the compensable quantity of distributed deterioration by extending one time slot of each series from plural light sources longer than that of an original transmission signal, adding the signals in an optimum optical frequency change state. CONSTITUTION:Frequency modulation signals 202, 203 and a DC bias current from DC bias sources 4, 5 are fed to semiconductor laser light sources 1, 2 via adders 6, 7. Signal sources 13, 14 generate RZ signals 204, 205 synchronously with a clock generator 8. The RZ signals 204, 205 are given to external modulators 17,18 as intensity modulation signals 206, 207 via a pulse width variable circuit 15. The modulators 17, 18 uses the intensity modulation signals 206, 207 to apply intensity modulation to output lights 101, 102 and output the result as transmission signal lights 103, 104. The transmission lights 103, 104 are subjected to time multiplex at a photocoupler 19 and its multiplexed transmission signal light 105 is detected by a photodetector 32 via an optical fiber 3.

Abstract: PURPOSE:To fix a down pipe firmly by installing a pair of engagement grooves on an outer peripheral surface on both sides of the down pipe and mounting a pair of clamping pieces with a gutter support hardware on both sides of a short article and inserting the paired clamping pieces into the engagement grooves. CONSTITUTION:A mounting unit 5, whose tip is sharply pointed, is pierced into the surface to be fixed, such as a wall or a post where a down pipe support hardware 2 is fixed with the fixed surface. Then, the down pipe 1 is inserted by expanding a pair of clamping piece 3 for the down pipe support hardware 2 and a projected strip 12 installed to the indoor-side outer peripheral surface of the down pipe 1 is placed in contact with a short article between the clamping pieces 3.

Title: Optical fiber cable element and manufacture and production unit thereof
Inventor: GANNON JOHN ROBERT
IPC: G02B6/44
Filed: 1986-10-03
Abstract: An optical fibre cable element (3A) for incorporation in an optical fibre cable (Fig. 4) for e.g. local area networks, comprises a plurality of optical fibres (3) held together solely by an adhesive which has been applied cold and air-dried. A suitable adhesive material is a solvent-based acrylic copolymer system. Preferably the shape of the cable element is a ribbon, but other constructions are also envisaged. The cable element is cheap to make and avoids the heat and pressure of extrusion in the construction of the cable element, thus minimising the risk of damaging the fibres by such heat and pressure. Very high fibre density is also achieved.

Title: Duty factor discrimination circuit
Inventor: SAKAMOTO HIDEKI
IPC: G01R29/02
Filed: 1988-09-20
Abstract: PURPOSE:To perform the discrimination of a duty factor even when the cycle of a pulse signal changes by measuring the cycle of the pulse signal, and latching the level of the pulse signal with a timing corresponding to the cycle. CONSTITUTION:A level discrimination time is set at a time when 55% from the rise of a reproducing control(PBCTL) signal 1 elapses. A CPU 3 starts an interruption processing by the generation of an edge detecting signal 13, and a value equivalent to the cycle of the 55% of the PBCTL signal 1 is written in a compare register 10. Since a count signal 40 coincides with a compare signal 42 at the time when the 55% of the cycle from the rise of the PBCTL signal 1 elapses, a comparator 20 outputs a coincidence signal 21. At this time, a D latch 23 latches the level of the PBCTL signal 1, thereby, an L level is latched when the signal is the one with a duty factor of 40%, and an H level when it is the one with the duty factor of 70%. The CPU 3 can discriminate the duty factor only by reading a duty factor discrimination signal 43 via a bus line.

Abstract: PROBLEM TO BE SOLVED: To easily produce a space truss composite board having a low height by forming triangular slits in a steel plate and protruding diagonal members to form square pyramids on a plane-lattice by press-forming and joining another steel plate on a flat part of the top. SOLUTION: Triangular slits 2 are formed on a steel plate 1 and quadrangular pyramidal ridge lines are protruded on a quadrilateral lattice by a press- forming and another steel plate is welded or adhered on a flat part composed of triangular fins formed on the top.
