Abstract: The invention relates to a control device for a lockable cooking apparatus having a heating device for heating the cooking compartment, the heating device interacting with a control device, which is controlled by a temperature sensor, for a definable temperature range, in that, for on-line optimisation of a cooking compartment temperature range of up to 100 DEG C which can be defined, the control device provides fuzzy control of the transient state of the initial temperature value, so that the heating-up peak is avoided using only one fuzzy control step, the control device recognises the decayed transient state and initialises an optimised heating time related to the first fuzzy control step. In the case of a minimum heating time, with continuous monitoring of the optimum switching-on temperature for the cooking compartment heating from the respectively identified temperature gradient, the control device updates the minimum heating time and continuously optimises the switching-on temperature via a closed control loop. <IMAGE>

Abstract: A method and an apparatus for on-line monitoring the quality of a purified metal sulphate solution is disclosed. The method comprises the steps of depositing metal from the purified metal sulphate solution onto a working electrode submerged in the solution by passing constant current through the solution at a current density in the range of 25 to 150 mAlcm 2  for a predetermined time interval, dissolving the metal deposited on the working electrode by reversing the polarity of the potential applied between the working electrode and a counter electrode so as to pass a reverse current of the same current density through the solution until all zinc is removed from the working electrode as sensed by a sudden change in electrode potential, deriving the quality index of the solution by calculating the ratio of the dissolution time over the deposition time, and restoring the surface of the counter electrode by effecting the dissolution of the metal deposited on the counter electrode at the end of each measurement.

Abstract: A communication protocol or method (40) that provides for terminal access, data flow, call monitoring and terminal polling, and call termination between user terminals (11, 12) connected to a high data rate satellite communication system. An "Aloha" random access channel that forms part of a bent-pipe architecture is used in conjunction with orderwire uplink and downlink channels to permit the system to cleanly and simply establish its data links and thus provide terminal access. A network control center (14) is used to assign a source user terminal (11) to uplink and downlink channels. After the communication link is established, uplinked data is demodulated, and routed to every downlink beam where it is multiplexed with other data channels, then remodulated and downlinked to every user terminal. The ordewire uplink is only from the network control center (14) to the satellite relay system, and uses the channel without demodulation and remodulation. The orderwire downlink is only from the satellite relay system to the user terminals (11, 12), and uses the channels with demodulation and remodulation. Each user terminal monitors its orderwire downlink channel to recognize and extract messages addressed to it. Data flow, call monitoring and terminal polling is performed once the source and destination user terminals (11, 12) have been assigned their beams and frequency and time slots. Thereafter, data transfer between terminals is generally independent of the network control center (14). Input data generated at a source user terminal (11) is multiplexed and transmitted to the satellite relay system. The satellite relay system demodulates the data, routes it so that it is retransmitted on a beam that communicates with the destination user terminal (12), remultiplexes and remodulates the data, and then transmits the multiplexed data to the destination user terminal (12). The network control center (14) monitors the link so that system resources are not unnecessarily tied up if a connection is lost. This is achieved by causing both terminals to send periodic messages to the network control center (14) indicating that they are active on the network, or the network control center (14) may periodically poll each terminal and terminate a call if either terminal is unresponsive or provides a signal indicating that it has hung up. Several call termination procedures are also provided.

Abstract: An MLR (multilayer resist) 3 is formed on a BPSG layer 2 on top of a silicon wafer 1, then dry etched using an etching gas 8 to form a contact hole 2a on the BPSG layer 2. Next, the polymer residues 9a and 9b adhering to the side walls of the contact hole 2a and the surface of the BPSG layer 2 are subjected to a cleaning treatment using a cleaning treating liquid that contains 0.04-0.12 wt% hydrogen fluoride, thereby removing the polymer residues 9a 
and 9b. 
     During etching the presence of the polymer residue layer 9 prevents etching in the horizontal direction, thereby allowing the formation of a highly precise contact hole 2a. In addition, because the treating liquid has the composition described above, the aforementioned polymer residues 9a and 9b are removed, thereby avoiding any degradation of the electrical characteristics. In addition, corrosion of the side walls of the contact hole due to the cleaning treating liquid is prevented, thereby maintaining the high level of contact hole precision. As a result good electrical characteristics are ensured even if the structure has an ultrafine-pitch pattern.

Abstract: A laser beam as fundamental waves which is emitted from a distribution Bragg reflection (DBR) semiconductor laser is incident on an optical waveguide of a light wavelength conversion device in which domain-inverted regions and the optical waveguide are formed in an LiTaO₃ substrate. The wavelength of the incident laser beam is then converted so as to obtain higher harmonic waves such as blue light. In the conversion, a drive current to be applied to a DBR portion of the DBR semiconductor laser is changed so as to change an oscillating wavelength of the DBR semiconductor laser, thereby matching the oscillating wavelength with a phase-matched wavelength of the light wavelength conversion device. Thus, the generation of the harmonic waves to be output is stably controlled.
