Patent EP-0414226-A2 (EP)
Inventor: NARITA KAORU
IPC: H01L27/092
Filed: 1990-08-22
Abstract: In a n-channel MOS transistor of LDD structure with sidewall spacers, a p-type diffusion layer is formed to be on the surface of a n⁻ drain layer just underneath the sidewall spacer and to be separated from the channel region. 
     The low impurity concentration drain layer therefore becomes separated from the sidewall spacer, and thus degradation incident to LDD due to injection of hot carriers into the sidewall spacer can be prevented.

Abstract: In a constant voltage circuit, when a second resistor element (13) is inserted between the base and collector of a first transistor (14) and between the other terminal of a first resistor element (11) and the base of a second transistor (16), a basic equation for calculating a bandgap voltage reference can be calcu­lated free from a base-emitter voltage of the third transistor (17). Therefore, since a change in base-­emitter voltage on the basis of a change in current flowing through the third transistor (17) does not appear as an output voltage, the output voltage can be stabilized.

Abstract: The object of the invention is to introduce a greater number of cation-active groups than hitherto possible into wax oxidates and to obtain a pale product in a gentle reaction. This is achieved by first reacting the wax oxidate, optionally after prior esterification by means of polyhydric alcohols, with a polyisocyanate and then with an N,N-dialkylethanolamine. After neutralisation, quaternisation or the like, emulsions having a highly substantive character which are suitable for painting and coating purposes can be prepared.

Abstract: This invention relates to arrangements for providing a new spontaneous voice message service to any telephone customer at any telephone station when that customer encounters any destination that is busy or that does not answer. When a customer having a dual tone multifrequency (DTMF) station calls any destination that is busy or does not answer, the customer is invited, via an announcement identifying the new service, to record the caller's voice message. The announcement accompanies the returned busy tone or audible ring signal. The customer keys *867 (= *VMS) and is then connected to a Voice Message Operations Center (VMOC) which prompts the customer to record the message. Advantageously, customers need not redial a VMOC number, their own number, and a destination number to reach a VMOC for storing the voice message; the added convenience of this arrangement should stimulate substantial additional use of voice message service. The announcement, at very low cost, makes the customers aware of the service at the time they are most likely to use the service.

Abstract: The clipping circuit has a voltage reference (3) and a transconductance (5) connected to a voltage input (Vin). The input is connected through the transconductance (5) to an output resistor (Rout). The voltage output is taken between the output resistor and the transconductance (5). The voltage reference (3) has a third current source (I₃) feeding a diode connected transistor (Q₁) and a resistor (R₁). A second current source (I₂) feeds into the resistor after the transistor. The base of the diode connected transistor (Q₁) is connected to the voltage input. The transconductance (5) has a second transistor (Q₂) whose base is connected to the voltage input, collector sinks current from a fourth current source and emitter feeds current to a resistor (R₂). A first current source (I₁) feeds. current to a third transistor (Q₃) and to a current mirror. The base of the third transistor (Q₃) is connected between the fourth current source (I₄) and the collector of the second transistor (Q₂). The current mirror draws current from the output resistor (Rout) and feeds current to between the emitter of the second transistor (Q₂) and its associated resistor (R₂). The transconductance creates a feed back loop such that a change in the first and second current sources creates a steady-state current drawn through the resistor (R₂) that is one-half of the first current source current. The circuit produces symmetrical clipping of an input voltage signal at the voltage output.

Abstract: The system unit (16) of an IBM compatible personal computer generates a distinctive audible "Beep" signal from the system unit's own sound transducer (32) in response to the successful decode of a barcode label (26) in a keyboard emulation data collection device such as a barcode reader (10). To initiate the generation of such a Beep by the system unit, the keyboard emulation system simulates (114,116) a benign error condition (OOH;FFH) which does not affect the operation of any application programs resident in the system unit and which does not require any modifications to the operating system or any special device drivers for its proper operation. The successful collection of encoded character data and transmission of that data to the keyboard port (28) of a host computer by a relatively unsophisticated operator is further enhanced by built-in logic (40,42,44) for reliably and simply deducing which keyboard communication protocol from several candidates is currently in use and for deducing the status of the computer's Caps Lock flag by eliciting a Reset Status Indicators command from the system unit. If the Caps Lock flag is in its shifted state, all case sensitive data is automatically transposed (114) so that it will be correctly interpreted.

Abstract: A method and an apparatus for voltage regulation are proposed, by means of which the battery charge state and the loads from the on-board network are determined and suitable measures to improve this charge state are initiated if the battery charge state is poor. The on-board network load is determined during a first period (t1) from the switched-on duration of the switching transistor (18) of the voltage regulator (12) and the speed of the generator. In a second period (t2), the charge state of the battery is determined from the behaviour of the battery voltage at a reduced regulation voltage.

Abstract: Electrodes for electrochemical processes, especially anodes for the cathodic protection of metal substrates, e.g. reinforcing bars in concrete, comprise a conductive core (11) which acts as a current-distributing member, an outer member (13) which provides an electrochemically active outer surface, and an intermediate member (12) composed of a material which is of higher resistivity, and/or which is less electrochemically active, than the material of the outer member. The higher the resistivity of the intermediate member, the more regular the current distribution along the length of the electrode. When the intermediate member is less electrochemically active, this protects the core from corrosion if the outer member is damaged by physical means or through electrochemical erosion. Preferably at least one of the intermediate member and the outer member is composed of a conductive polymer, especially one comprising carbon black or graphite as conductive filler.

Abstract: This invention relates to an in-ash unburned component estimating device for a coal-fired furnace which monitors the density of in-ash unburned component contained in burning waste gases to operate the furnace efficiently. The object of the invention is to infer and estimate from the current situation by a simple means the density of in-ash unburned component in the burning exhaust gases that affects the combustion efficiency. A furnace temperature, a load band in the furnace, a furnace contamination coefficient, a ratio of two-stage combustion air supplied to the furnace, and a coal mixture ratio are taken in as fuzzy quantities to infer fuel ratio data and correction data used to correct predetermined reference values of reference in-furnace temperature distribution, reference in-furnace air ratio distribution and reference powdered coal grain diameter distribution. The reference values corrected by the correction data and coal reaction rate data determined from the fuel ratio data are used to calculate the density of in-ash unburned components in the burning waste gases.
