Title: Wavelength division multiplex optical communication network provided with passive path through in each node
Inventor: MILTON DAVID
IPC: H04B10/548
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To establish direct communication between a pair of nodes without the positive intervention of an interposed node by providing an interface or the like for branching a band related to the node in each node, synthesizing bands for conveying traffic to the other node and passively sending the other bands. SOLUTION: Respective nodes 4-8 branch/synthesize the prescribed band of a specified wavelength in respective nodes. For example, the node 6 branches a band containing the wavelengths of 1.52411, 1.52256, 1.52102 and 1.51948 μm. In order to form a route between the nodes 4 and 6, the node 4 performs the transmission of this band through both inverse rings 2 and 3 to the node 6. This band is passively reflected by the nodes 5, 7 and 8 and this band is branched and sent to the node 6 for extracting the traffic. Therefore, even between any nodes on the ring, without interposing any intermediate node, the connection is directly enabled without regard to a protocol.

Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of an optical surge pulse by inserting laser light to a break of signal light in switching from a current light source to a standby light source. SOLUTION: A signal light source 111 is arranged in an optical transmission equipment 11. An optical branching device which branches a part of signal light is provided in an optical waveguide connected to this optical transmission equipment, and a photo detector 22 which detects the output of signal light is connected to the optical branching device 21. A control circuit 23 controls the output of a laser light source 24 in accordance with the detection output of the photo detector 22, and laser light from the laser light source 24 is inserted to the optical transmission line from an optical synthesizer 25.  For example, the control circuit 23 stops the laser light source 24 in the case of the output of the photodetector 22 larger than -15dBm; and when the output of the photodetector 22 is reduced to -15dBm or lower, the circuit 23 makes the laser light source 24 emit light to control the output from the optical synthesizer 25 to +5dBm.

Title: Magnetic recording medium
Inventor: TAKEUCHI YOJI
IPC: G11B5/64
Filed: 1987-11-06
Abstract: PURPOSE:To improve the traveling property and durability of the tile medium by using a pentaerythritol deriv. having fluorinated alkyl groups as a lubricating agent. CONSTITUTION:This magnetic recording medium contains the pentaerythritol deriv. having >=1 fluorinated alkyl groups (e.g.: the compd. expressed by formula). In formula, X1-X4 are H or carboxylic acid residue; >=1 of X1-X4 are fluorinated carboxylic acid residue. The compd. expressed by formula II is usable as the above-mentioned compd. and may also be used in conjunction with other lubricating agents. Since the compd. expressed by formula has a large mol.wt., the rate of evaporation at the time of a coating stage is small and the quantity of dissipation during preservation is small and, therefore, said compd. is capable of maintaining the good lubricating effect over a long period of time.

IPC: G06F17/50
Filed: 1986-11-26
Abstract: PURPOSE:To simplify the control of an output drawing as well as a function tracing job by outputting plural logic circuit diagrams after synthesizing them. CONSTITUTION:The drawing names to be synthesized to the same drawing an the layout order are designated from a terminal equipment 3 by a command. This command is stored temporarily in a synthetic drawing name designating command storing area 14 and a retrieving/extracting means 15 is started. Then the information on the designated drawing is retrieved out of an external memory file 4 based on the command stored in the area 14 and stored successively in a synthetic drawing information storing area 16. Then a drawing synthesizing means 17 is started and the drawing information is read successively out of the area 16. Thus a drawing image is produced before the synthesization processing and stored in a pre-synthesization area of a logic circuit diagram image storing area 18 to undergo synthesizing processing. This synthesized drawing image is stored in an after-synthesization area of the area 18.

Filed: 1986-11-28
Abstract: PURPOSE:To input serial data during the output period of serial data by reading the data serially based on a clock signal specifying one picture element and inputting the data to a latch circuit serially. CONSTITUTION:A clock signal phiy fed through an external terminal CLK is used as a clock signal to specify one picture element and a data line selection signal inputted to a shift register YSR is shifted by the said signal phiy.

Abstract: PURPOSE:To detect a pressure loss value of a filter accurately by discontinuing particulate collection at an appropriate time, and detecting the pressure loss value of the filter by means of a constant volume of gas supply without recourse to the operating condition at that time. CONSTITUTION:In the case of operating an engine, in a control circuit 5, the judgment is made by observing on whether or not it is a predetermined particulate collection volume measuring time, for example, on whether or not a timer counter is more than a prescribed value, and in the case of YES, signals to open the first-the third switching valves 11, 15 and 17 are outputted to respective actuators 11, 18 and 19. Furthermore, approximately in synchronism with these, an air pump 13 is driven, and a constant flow rate of air is flown toward a filter 1 from the air pump 13. Under this constant flow rate of air supply condition, in order to detect pressures Pf and Pr in front and in rear of the filter 1, output signals of pressure sensors 8 and 9 are taken in so that a pressure loss value (Pf-Pr) can be found from the obtained pressure values Pf and Pr. Next, the present particulate volume (w) can be obtained by carrying out an operation based on this pressure loss value.

Abstract: PURPOSE:To reduce the dispersion of resonant frequencies by providing second grooves having the same depth as a first groove at mutually different positions of the both surfaces of a supporting plate. CONSTITUTION:Electrodes 11 are formed on the both disk surfaces of a piezoelectric member 14, and bonded to a supporting plate 15. A first groove 16 having the even depth to partially bond the piezoelectric member 14 to the surface to be bonded is formed. Between the external peripheral part of the piezoelectric member 14 and the support fixing body 17 to support the external periphery of the supporting plate 15, second grooves 18, which are at mutually different positions and have the same depth as that of the groove 16, are prepared. A thermoplastic substrate 24 is used for the supporting plate 15, the substrate 24 is pinched by upper and lower molds 21 and 22 projecting at a part corresponding to the groove, heated and left for a prescribed time, then pressure is applied, and the groove is shaped on the substrate 24. That is, since the depth of the first and second grooves 16 and 18 can be controlled to a constant value by the height of a projecting pattern formed on the upper and lower molds 21 and 22 and the width of the frame 25 placed between the molds, the dispersion of the resonant frequencies can be reduced.

Filed: 1989-10-30
Abstract: PURPOSE:To improve the throughput of a memory controller by providing a data counting area at the head of a memory to store the data count value. CONSTITUTION:The data areas 32-1 - 32-n of a control memory 26 store the control instruction data respectively. The data count value stored in a data count area 31 is increased by a central controller 21 and decreased by a device 28 to be controlled. The data count value shows the number of pieces of control instruction data written in a data area 32. Under such conditions, the data count value is increased by an amount equal to the number of data written into a memory and decreased by an amount equal to the number of data read out of the memory. Thus plural pieces of data can be processed at one time. Then the writing/reading process efficiency is improved to the memory.
