Abstract: The pot detection system operates with an inductive sensor (22) which is arranged close to the heated region of the cooking apparatus (11). The sensor signals are evaluated as a function of the signal rate of change in order to compensate for the poor coil quality of the high-temperature-resistant coils. The evaluation takes place digitally with frequency counting, and a bridging device (50) is provided in order to be able to use the apparatus even without pot detection.

Abstract: A method of fabricating integrated circuit structures on semiconductor wafers using a plasma-assisted process is disclosed wherein the plasma is generated by a VHF/UHF power source at a frequency ranging from about 50 to about 800 MHz. Low pressure plasma-assisted etching or deposition processes, i.e., processes may be carried out within a pressure range not exceeding about 500 milliTorr; with a ratio of anode to cathode area of from about 2:1 to about 20:1, and an electrode spacing of from about 5 cm. to about 30 cm. High pressure plasma-assisted etching or deposition processes, i.e., processes may be carried out with a pressure ranging from over 500 milliTorr up to 50 Torr or higher; with an anode to cathode electrode spacing of less than about 5 cm. By carrying out plasma-assisted processes using plasma operated within a range of from about 50 to about 800 MHz, the electrode sheath voltages are maintained sufficiently low, so as to avoid damage to structures on the wafer, yet sufficiently high to preferably permit initiation of the processes without the need for supplemental power sources. Operating in this frequency range may also result in reduction or elimination of microloading effects.

Filed: 1991-08-06
Abstract: RF power is sampled and measured at the input and output of a solid state power amplifier using directional couplers (54,55) and matched square law detectors (60,61). Outputs from the detectors are applied to differential inputs of a DC operational amplifier (62). Outputs from the detectors are compared and filtered in the operational amplifier and the resulting difference signal is applied to a control input on a switching type power supply (64). The power supply converts a DC input voltage to the various positive and negative voltages required to operate the RF devices (72-75) in the solid state power amplifier. When the control loop is closed, the supply voltage varies to maintain a constant operating point resulting in constant gain, efficiency, and linearity for the overall solid state power amplifier despite variations in signal levels and signal composition. In another embodiment, the solid state power amplifier has a series of single-ended low power amplifiers terminating in an output high power module. In the output module, one medium power device acts as a driver stage (45) for four high power devices (72-75) connected in parallel. The output stages are hybrid coupled, and isolators before and after these hybrid coupled output stages isolate the driver from the final amplifiers and protect the output devices from reflected signals. A dynamically controlled PIN diode variable attenuator (42) at the amplifier input allows the operating point of the amplifier to be selected and adjusted while the closed loop function is in operation. A hybrid matrix power amplifier system is also disclosed.

Abstract: In a method for determining components of a body fluid and an apparatus for carrying out the method, a body fluid-sampling cell comes in close contact with the skin of the human body and the body fluid is sampled from the skin by aspirating, under negative pressure, the skin through an aspiration port with a suction pump. A housing is positioned over a body fluid-sampling path which communicates the sampling cell to the suction pump and a quantity measuring valve arranged therein has a through hole which simultaneously serves as a reservoir for the body fluid. The through hole of the valve is rotated by a controller, then the constant amount of the sampled body fluid is forced into a flow type measuring cell through the measuring path by a liquid supply pump and the components of the body fluid are detected and determined by a sensor arranged within the measuring cell. The apparatus and method makes it possible to precisely determine the concentration of a specific component present in a very small amount of the body fluid and to continuously monitor the concentration.

Abstract: The present invention is directed to a solid state image sensing device which can reduce a consumed amount of an electric power. 
     During a horizontal blanking period, a vertical scanning pulse of 5V is supplied to a vertical selection line (2A) from a vertical scanning circuit (3). In synchronism therewith, a voltage (φI) is changed from 5V to 0V and a voltage (φVGG) is changed from 0V to 5V. Thus, a source switch transistor (6) is turned off and a load transistor (9) is turned on, whereby a source follower circuit formed by a pixel transistor (12) and the load transistor (9) of a unit pixel (1) is set in the operable state to read an electrical signal accumulated in the unit pixel (1). According to the present invention, the load transistor (9) is turned on by the application of the voltage (φVGG) only during the electrical signal read-out period and the dark signal read-out period of the unit pixel within the horizontal blanking period. Since a current is flowed to the pixel transistor (12) by a power supply (7) only during this period, a consumed electric power can be reduced considerably as compared with the prior art.

Abstract: In order to correct a track zero-crossing signal TZC generated from a signal detected by an optical head of an optical disk system, an expected edge pulse (NP) and a window signal (WD) are generated at the position at which the appearance of the edge of the track zero-crossing signal is expected. Among the edge pulses of the actual track zero-crossing signal, only those that exist inside a window are allowed to pass through. When the edge pulses do not exist within the window, the expected pulse is inserted so as to generate a corrected edge pulse, and a corrected track zero-crossing signal is generated from this corrected edge pulse.

Abstract: The apparatus for layering powder (157) onto particles (191) has a vessel (1) in which a rotor (21) is mounted rotatable around a vertical axis (3). The rotor (21) comprises a disc (23) with a supporting surface (23a) for supporting particles (191). The apparatus also has feeding means (67) with a substantially horizontal introducing member (71) protruding slightly into the vessel (1) above the disc (23). The introducing member (71) limits a liquid outlet and an annular powder outlet encompassing the liquid outlet. During a layering operation, the introducing member (71) protrudes into a bed of particles (191) lying on the rotating disc (23) and moved by the latter. There can then be sprayed liquid (129) and powder (157) simultaneously by one and the same introducing member (71) onto the particles (191) passing in proximity of said outlets. This enables layering powder (157) onto particles (191) and to produce thereby pellets having sizes lying in a narrow range, wherein the pellets can be produced by using only a small amount of liquid and in short time.

Abstract: Antibodies which are specific to a thermostable DNA polymerase can be used to reduce or eliminate the formation of non-specific products in polymerase chain reaction methods. These antibodies and other temperature sensitive inhibitors are effective to inhibit DNA polymerase enzymatic activity at a certain temperature T₁ which is generally below 85 o C. The inhibitors are irreversibly inactivated at temperature T₂ which is generally above 40 o C. T₂ is also greater than T₁. Such inhibitors can be supplied individually or in admixture with the DNA polymerase in a diagnostic test kit suitable for PCR.
