Filed: 1988-12-15
Abstract: PURPOSE:To perform non-destructive inspection with high reliability and to enhance the quality of a product by confirming whether the intermediate adhesive layer of two resin layers is present as a layer having two interfaces. CONSTITUTION:A reflected wave F caught by a probe 7 is amplified by a control circuit part 6 and the amplified reflected wave F is passed through a high-pass filter 8 to be inputted to an adhesive layer discriminating circuit part 9 to discriminate the adhesive layer 4, and a CRT display 10 and a printer 11 are also provided.

IPC: H01L21/3205
Filed: 1987-12-18
Abstract: PURPOSE:To enable a high reliability superconducting wiring maintaining a flat structure to be realized, by a method wherein an oxide superconducting thin film containing Cu therein is formed on a substrate, atoms easy to replace Cu positions are then implanted into the region other than the wiring region of the oxide superconducting thin film to leave supercon ductivity only in the wiring region. CONSTITUTION:An oxide superconducting thin film 2 containing Cu therein is formed on a substrate 1, and atoms easy to replace Cu positions are then implanted into the region 22 other than the wiring region 21 of the oxide superconducting thin film 2 to leave superconducting characteristics only in the wiring region 21. For example, an YBa2Cu3O7-delta film 2 is formed allover on the surface of a MgO substrate 1 by means of sputtering. Now, during the formation of the film 2, if elements formed in the substrate 1 are not affected, the sputtering will be performed with the temperature rising up to above 600 deg.C or so in the whole structure. On the other hand, in the case of the temperature can not be caused to rise during the sputtering, after the thin film 2 is formed at room temperature, annealing is performed in oxygen plasma at about 300 deg.C. Next, a mask 3 is formed on the wiring region 21 by patterning a photoresist, and Fe ions are then implanted into the non-wiring region 22 through the mask 3 to break the superconductivity thereof. Subsequently, the mask 3 is removed, thereby a wiring formation process is completed.

Abstract: PURPOSE:To provide a loop type communication system which can keep the high availability of the time slots despite the occurrence of a separate loop by choosing a time slot of the higher priority when the loops are integrated and the competition is caused among the time slots. CONSTITUTION:When a loop is divided into the separate loops A and B, the control stations 1-1 and 1-2 serve as the master stations of both loops A and B respectively. Then both loops A and B are integrated together and the station 1-2 finally serves as a mater station of the integrated loop. Then the station 1-2 acquires the information (priority) on a subject time slot from a received message and compares this information with the priority of its own A-SVS time slot control table. If the priority of the station 1-2 is higher than the notified priority of the station 1-1, the station 1-2 gives a release request to the station 1-1. If not, the station 1-2 notifies the use permission to the station 1-1 and assigns its own A-SVS time slot control table.

At this time, it is preferable that the integrated value of the current in the reverse direction by the reverse is set 25-175% of an integrated current value in the forward direction. It is ideally preferable that the current in the reverse direction substantially having the same quantity as that in the forward direction is imparted. In other words, the conductive member 1 is operated by a cycle that the integrated current value in the reverse direction only for suppressing the rising rate of resistance by the application of the voltage is applied, the rising of the resistance value of the conductive member 1 can be suppressed.
