Title: Optical communication equipment
Inventor: NAKAMURA KENJI
IPC: H04J14/02
Filed: 1990-01-19
Abstract: PURPOSE:To eliminate the need for strict stabilization of a luminous wavelength by providing an interference avoiding means varying a wavelength used by its own terminal equipment so as to avoid interference with other terminal equipment when a detection means detects the operating wavelength at an wavelength region in the vicinity. CONSTITUTION:When a light of wavelength lambda2 enters a pass band of a wavelength variable filter #2 (552), an output of a photodetector #2 (562) increases. An output of a photodetector #3 (563) is unchanged. Thus, an adjacent channel access detection circuit 57 checks an output of both the photodetectors to detect it that lights with a wavelength shorter than a wavelength lambda1 are accessed. The circuit 57 sends the detection information to a control circuit 58 and uses a wavelength control signal to move consecutively the wavelength of a wavelength variable light source 51 in a longer direction thereby avoiding the interference with the wavelength lambda2. Simultaneously, a transmission wavelength control signal of wavelength variable filters #1 (551), #2 (552), #3 (553) is used to make the wavelength lambda1 after movement coincident with the transmission center wavelength of the filter #1 (551).

Abstract: PURPOSE:To eliminate the need for strict management of a reference wavelength and an absolute wavelength by providing a means to find out a wavelength not in use from an entire wavelength region and a means finding out a call signal or a confirmation signal to its own terminal equipment. CONSTITUTION:A transmission desiring terminal equipment 12 sweeps a transmission wavelengths lambdaA-lambdaB a wavelength variable filter 55 to check the operating state of a wavelength in the entire available wavelength area and to select a 1st wavelength lambda1 among wavelengths not in use. Then the terminal equipment 12 uses the wavelength lambda1 starts sending a call signal including information to identify its own terminal equipment 12 and a destination terminal equipment 23 by using the wavelength lambda1. The terminal equipment 23 recognizes a call signal to its own station to prepare the reception. At first, the wavelength area from lambdaA to lambdaB is checked to find out a 2nd wavelength lambda2 not in use. Then a confirmation signal including the information of starting reception of the call signal and of end of reception preparation is sent by using the wavelength lambda2. The terminal equipment 12 recognizes the finished preparation of the terminal equipment 23 by receiving the confirmation signal and uses the wavelength lambda1 to start the transmission of the information to the destination terminal equipment.

Abstract: PURPOSE:To detect the opposed force as shearing force by making stagger shelf type cuts which overlap and separate on a center axis as necessary and run to sides in the opposite directions centering the axis, and by concentrating stress on the overlap area of the cuts. CONSTITUTION:In an elastic plate 10 as shown by a parallelogram ABCD cuts 12' and 12'' which have an overlap (d) on a center axis and each extend to side edge of one side by length 1/3(D+d) are made in parallel to top and bottom sides AC and BD at an interval (l) and in a stagger shelf shape. Between those cuts 12' and 12'', two couples of strain gauges 14' and 14'' having axes with 45 deg. to the center axis of the plate 10 are provided on both the surfaces over the overall overlap width (d). When tensile forces F' and F'' in the opposite directions operate on both the ends of this strain detection plate at distance (e), the (e) increases by DELTAl. Then, the overlap part (d) is displaced as shown by a dotted line to increase the interval (l) by DELTAl, and a bridge is formed by using the gauges 14' on both the surfaces receiving tensile strain and the gauges 14'' on both the compressed surface as diagonal sides, thus detecting shearing strain with doubled sensitivity.

Abstract: PURPOSE:To make the oscillated frequency stable and to attain a high oscillated frequency by using a conductor pattern formed to both sides of a dielectric base so as to constitute the capacitance. CONSTITUTION:Three conductor patterns 2 respectively corresponding to paths of a base, a collector and an emitter of an oscillation transistor(TR) are formed to the surface of the dielectric base 1 and the oscillation TR is mounted. On the other hand, a conductor pattern 3 of a frame shape is formed to the rear side of the dielectric base 1 so that each is overlapped to the conductor pattern 2. Then capacitors C1-C3 are formed by using the overlapped areas between the conductor patterns 3, 2 and employing the dielectric base 1 as the dielectric substance of the capacitors. Thus, no chip capacitor 7 is used for the capacitors C1-C3 deciding the oscillated frequency. Thus, the oscillated frequency is made stable and the conductor pattern 3 as the inductance is provided to the other side of the oscillating element to miniaturize the circuit and to realize a high oscillated frequency.

Abstract: PURPOSE: To accomplish a large revetment at a great depth previously impossible with a higher revetting capacity by building a revetment in such a mannner that the back earth pressure working on a revetment is resisted by friction force due to gravity and a lateral resistance of a piling body.

Here, to mount the piling body 11 to a upper heavy thing 10, the piling body 11 is inserted into a hole 12 formed in the heavy thing through a ringlike member 13 thereby making it movable in the vertical way. In such a method, even when the subsoil 5 sinks, the upper heavy thing is always left placed on the subsoil 5 not lifting therefrom. Thus, the resistance against a pressure of back earth 4 is born by a friction force between the heavy thing 10 and the subsoil 5 and the lateral resisting force of the piling body 11 thereby increasing the reveting capacity.

Filed: 1988-01-20
Abstract: PURPOSE:To reduce the driving force of an actuator portion necessary for displacing a diaphragm by pressing the top face of a liquid in a through hole with the plunger and displacing the diaphragm. CONSTITUTION:As a plunger 6 which sealingly slides in a small-diameter through hole 32 provided on a cover 3 is driven downward by means of an actuator on top of the cover 3, the bottom face of the plunger 6 presses a liquid level in the through hole 32. Thereby, the liquid presses the whole top face of a diaphragm 2 downward, which is displaced downward closing a valve. At this time, since the area of bottom face of the plunger 6 for pressing the liquid in the through hole 32 is sufficiently small as compared to the area of the top face which receives the liquid pressure of the diaphragm 2, the diaphragm 2 can be displaced by the small pressing force of the plunger 6.

Abstract: PURPOSE:To prevent a workpiece from being subjected to any damage by mixing at least chlorinated sodium cyanurate, sodium tripolyphosphate and sodium sulfate into water, in the case of a polishing liquid used for polishing the mirror- like surface of substrates made of monocrystal of gallium arsenide. CONSTITUTION:Chlorinated sodium cyanurate, sodium tripolyphosphate and sodium sulfate are blended together by respective rates, for instance, 23g, 39g and 38g and dissolved in 2,777cc of pure water. Thus obtained polishing agent is used for polishing gallium arsenide substrates 2 stuck to a polishing jig 1. In this case, a reaction product 4 consisting of Ga2O3, and As2O3 is formed on the surface of gallium arsenide 3 by aid of hypochlorous acid generated from chlorinated sodium cyanurate dissolved in pure water and the protruding portions of this product are swept off by polishing cloth 5 and a reaction product 6 is formed again. These processes are repeated alternately to form a flat and smooth mirror surface-like polishing state. A mirror-like surface polishing process of high accuracy can be carried out in this way, without giving any damage to a workpiece.
