Title: Line branching device
Inventor: KAWADA YUTAKA
IPC: H04L12/40
Filed: 1990-10-20
Abstract: PURPOSE:To select a line which is free from interference at the time of signal reception by delaying a received signal from one line through a delay circuit by a much longer time than a propagation time difference. CONSTITUTION:Signals when sent to lines A and B are received by line receivers 31A-R and 31B-R and the received signals are outputted, the received signals are outputted to AND gates 34 and 36 while the signal of the line A is sent directly and the signal of the line is passed through an 8-bit delay circuit; and they are inputted to carrier detecting circuits 38A and 38B. The delay time of the delay circuit 35 is so set that the delay of the line-A received signal behind the line-B signal due to the route difference between the two communication lines can be absorbed in case, so the detection signal from the line A is inputted earlier to a decision control part 7. If the line A is in this trouble, only the output of the line receiver 31B-R of the line B appears, so the received signal of the line B is sent out to a slave station line C.

Filed: 1990-10-20
Abstract: PURPOSE:To enable reading for scanning from any direction and to improve reading rate by combining plural readable wires with different colors and different diameters and forming them in the shape of a ring into a cord. CONSTITUTION:A cord 1(a) is formed by combining white wires 2A, 2B,... and black wires 3A, 3B,... while setting them at different width and arranging them to form concentric circles with different diameters, respectively. An explanation character K is marked below them. By ensuring that the approximately center position of the circles can be scanned with a laser beam as shown with a solid line when the laser beam of a scanner scans the cord, it can be ensured that the laser beam can passes through the cord 1(a) when the scanning is performed from any direction (360 degrees) and therefore, the reading can be enabled. Thus, the reading can be enabled for the scanning from any direction and the cord with which the reading rate can be improved can be obtained.

Filed: 1987-11-11
Abstract: PURPOSE:To perform rapid measurement with good accuracy, by setting a function and automatically setting the waiting time corresponding to a certain time constant at the time of the setting of said constant. CONSTITUTION:A response speed setting part 14 and a delay time setting part 18 are mutually connected as a circuit.

Title: Maintenance state management method for subscriber stored in other station
Inventor: TAGUCHI SHINICHI
IPC: H04Q11/04
Filed: 1992-10-22
Abstract: PURPOSE:To manage a fault and a blocked state on the other station-side of a subscriber stored in the other station in a master station exchange. CONSTITUTION:The subscriber 5 stored in the exchange 3 of the other station 1 is connected to the exchange 4 of a master station 2 through a digital multiplex transmission line 6. The exchange of the master station executes a connection processing in the same way as the subscriber of a self station. Information on the fault or blocking relating on the subscriber 5 stored in the other station, which occurs on the other station-side, is collected by a maintenance information collection means 11 on the other station-side as maintenance information. A monitor/maintenance information synthesis means 12 combines maintenance information with monitor information of the subscriber stored in the other station and transmits them to the digital multiplex transmission line 6. The monitor/maintenance information extraction means 21 of the master station extracts monitor/maintenance information transmitted to the digital multiplex transmission line and transmits them to the connection processing part 22 of the exchange 4.

Title: Optical recording medium
Inventor: FUJII HITOSHI
IPC: G11B7/2433
Filed: 1986-11-28
Abstract: PURPOSE:To impart recording characteristics stable with time to enable high- sensitivity recording/regeneration, by a method wherein an optical recording material having no void and consisting of a light reflecting layer and a sensitizing layer is cut off from outside air by a transparent sheet. CONSTITUTION:On a substrate 1, an adhesive layer 2, a sensitizing layer 3, a light reflecting layer 4, a transparent sheet 7, and a surface protective layer 8 are laminated in this order. The sensitizing layer 3 is so provided as to be in close contact with the light reflecting layer 4, and an irradiating light beam fuses the light reflecting layer 4 made of a high-light reflectance metal film to form a recording portion. The use of a thermoplastic resin as a material of the sensitizing layer causes remarkable effects on the enhancement of recording sensitivity and the stability with time. On the other hand, the addition of a light absorber to the sensitizing layer accelerates the effects. The transparent sheet 7 molded integrally with a tracking guide groove 9 protects an optical recording material consisting of the light reflecting layer and the sensitizing layer by cutting it off from outside air. The surface protective layer 8 enhances the sensitivity in recording/regeneration on the action of preventing a laser beam from reflecting in recording/regeneration.

Abstract: PROBLEM TO BE SOLVED: To reduce a cost without a possible force for damaging an extrusion molding to the molding by extruding the molding, disposing it on an upper surface of a loop-like conveying web, solidifying it, and then separating it from the web. SOLUTION: A flange 16 is extrusion molded from flange die 12, and a molding 18 is extrusion molded from a molding die 14. The flange 16 which is extrusion molded is disposed on an area supported by a cast roller 24 of a continuous conveying web 20 and co-extruded on one or both side surfaces. A surface shape provided on an upper surface of the web 20 is transferred to the surface of the flange 16. Then, adhesive properties to a base such as a package made of a plastic are enhanced to prevent leakage of a fluid from the adhesive surface. And, the flange 16 can be separated from the web 20 at a separating point 36. The flange 16 and a molding 18 are cooled by an air nozzle 22, solidified, and the flange 16 and the molding 18 are separated from the web 20 at the point 36. Thus, a cost can be reduced without giving a force for damaging the molding 18.

Title: Method for stabilizing thermal-cracking oil of waste polymer
Inventor: TAKATSUKA TORU
IPC: C10G27/00
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To enable the wide improvement of the stability of a thermalcracking oil and the grade-up to a high quality oil by subjecting the thermal-cracking oil to an oxidation treatment. SOLUTION: A thermal-cracking oil obtained by high-temperature thermal cracking of polymer waste in the presence or absence of a catalyst is graded up to a high quality oil by subjecting it to an oxidation treatment bringing the oil into contact with an oxidizing agent.
