Title: Electrochemical sensor
Inventor: DEPREZ JACQUES
IPC: G01N27/416
Filed: 1992-08-17
Abstract: The electrochemical two-electrode sensor essentially comprises an organic gel electrolyte measuring cell (1) and a filter (10) permeable for the components to be measured. The measuring cell is designed in such a way that, in the presence of at least 2 ppm of phosgene or at least 15 ppm of hydrogen cyanide, it generates a signal of at least 50 nA. Upstream of the measuring cell (1) there is, in addition to the filter consisting of a silver sieve (10), an aperture (7) which limits the effective electrode surface at the three-phase boundary gas space/measuring electrode/electrolyte. Furthermore there is disposed, upstream of the aperture (7), a convection barrier consisting of a porous sheet (PTFE). The components to be measured (12) thus first diffuse through the silver sieve (10), then through the convection barrier (9) and finally through the aperture (7, 8) before they reach the three-phase boundary at the surface of the measuring cell (1). Additionally, a second convection barrier (11) may be provided. <IMAGE>

Abstract: A tire uniformity inspection machine (10) is calibrated by applying to at least one force measuring channel thereof a signal which simulates the application of a force of a magnitude greater than any force actually applied to the machine during calibration. That signal, which is preferably of a magnitude appropriate to simulate the largest forces encountered during actual tire testing, can be generated by connecting the channel, preferably at its input, to an energy source (V+) through an impedance (Z1, Z2). The response of the channel to the signal is measured and a calibration factor is determined based on that response. Such calibration factor accounts for the actual behavior of the channel more truely than prior art calibration techniques which relied solely upon the relatively small signal excitation conditions achievable by applying a relatively small actual force to the machine. Thus, the invention affords tire uniformity measurements of improved accuracy.

Abstract: If the process were to be changed for optimizing the injection of hot electrons into the channel of the memory transistor in the manufacture of an integrated circuit comprising an embedded EPROM, this could lead to degradation of the transistors in the logic, in particular in the case of channel lengths below 1 µm. To prevent this, a process is presented by which the non-volatile memory is optimized without the properties of the logic being affected by this. For this purpose, according to the invention, a first series of steps is performed in which first the floating gate is defined, followed by the source/drain implantation and a side-wall oxidation for obtaining an oxide spacer on the sides of the floating gate. During these steps, the region of the logic to be formed is uniformly protected against implantation and oxidation by the same poly layer from which the floating gate is made. Then, in a second series of steps, the usual CMOS process is carried out whereby first the gates of the transistors are formed, followed by the necessary source/drain implantations.

Abstract: According to the invention, whether a print head (15) of, for example, the thermal jet system has been capped or not is informed to the user, thereby preventing that the user turns off the power source when the head is not capped. Even when the user turns off the power source in spite of the fact that the head is not capped yet, the capping status is checked before the power source is turned off. After the head (15) was capped, the power source is turned off. Due to this, it is prevented that the print head (15) is left while the head is not capped yet. The choking of the nozzles can be prevented.

Abstract: This invention provides an easy backup, restoration and migration method of a database system. The command interpreter receives a backup request and the controller identifies the backup object in the backup request by referring to the definition. The backup-migrate-restore-procedure generator generates a backup procedure of the backup object identified by the controller by referring to the definition. The controller converts the backup object to a command form of SQL in accordance with the procedure generated by the backup-migrate-restore-procedure generator and stores in the storage medium. The stored data are the replace information, definition, dependence information, data, journal and program. Restoration of the system and migration of the database to another system is enable by inputting such data. Backup, migration and restoration of a system is able to be made in an identical apparatus. Furthermore, since a command form of SQL is used, a special means is unnecessary for migration and restoration.

Abstract: A digital communication network carries high and low priority data. The network stations that produce high priority data are assigned to a first group of stations and stations that produce low priority data are assigned to a second group with the two group not being mutually exclusive. Activity on the network is divided into periodic intervals of the same duration. Network control information, that defines how access to the medium, is determined is broadcast to all stations during a first segment of a periodic interval. The network control information defines the length of the periodic interval and of the periodic interval segments, and defines how many stations are in each group. Then during a second segment of the periodic interval, every station in the first group is afforded an opportunity, in a predefined order, to transmit high priority data over the medium. Stations in the second group are afforded an opportunity to transmit low priority data, when time remains after the first segment in a periodic interval before the network control information will be transmitted again. The specific station in the second group which is afforded an opportuinity to transmit first changes from periodic interval to periodic interval.
