Abstract: In a first heterojunction bipolar transistor (HBT) of the present invention, base layers (105,106) and collector layers (103,104) are respectively divided into a plurality of layers and one of the base layers (105,106) provided closer to the collector layer region (103,104) is set lower in impurity concentration than the other thereof provided closer to an emitter layer (107), thus solving a problem that thermal histories during epitaxial growth or during processes cause a set impurity distribution to be destroyed due to diffusion and thus a heterojunction is shifted from a p-n junction. Since minority carriers in the base can smoothly flow toward the collector, there can be realized an excellent HBT having a very high current gain and a very high cut-off frequency. 
     In a second HBT of the invention, a base region (204, 205) comprises a first base layer (205) of a low concentration having the same energy band gap as an emitter region (206) and to be changed to a complete depletion layer in a thermally balanced state and a graded second base layer (204) of a high concentration, and the first and second base layers form a heterojunction, thereby realizing an excellent HBT having a high speed performance which can exhibit a sufficient grading effect while preventing deterioration of an emitter-base voltage withstanding characteristic. 
     Further, in a third HBT of the invention, since an emitter region (306,307) comprises a first emitter layer (307) and a second emitter layer (306) of a lower concentration made of the same material as the first emitter layer while a base region (304,305) comprises a first base layer (305) having the same energy band gap as the emitter region (306,307) and a second base layer (304) narrower in an energy band gap than the first base layer (305), an excellent HBT having a high operational speed can be realized.

Abstract: 2.1 A special calling device is to be used for forming a calling criterion which informs a person to be called of an incoming call in such a discrete manner that the attention of uninvolved persons is not attracted. In this case, the portable communication terminal with this calling device or the calling device as a single set should be so small and handy that it can be carried on the body of the user. 2.2 When a call signal is received, a pulsating force field is generated in the special calling device, vibrations being produced by a vibrating armature moved by this field. This informs a user of a call without an audible or visible signal being produced, which signal could be considered a nuisance in the immediate vicinity. 2.3 An incoming call is distinctly noticeably detected only by the user without this being perceived in the immediate vicinity. Depending on the situation, the user can then decide whether he wishes to leave the room to answer the call, so that other persons are not disturbed. <IMAGE>

IPC: H02J3/38

Abstract: Switching of three phase wye power can be efficiently completed without synchronization between two or more energy sources. The absence of synchronism can be overcome by switching one source off and then in a very short time frame restoring the power from the second power source. The duration of the outage can be controlled and minimized so that the load never loses energy long enough to cause an operational problem. The interruption time period in this description is limited to about 100 microsecond span; long enough to avoid interaction between the separate power sources, yet short enough to be transparent to the load. Electrical transfer of loads between power sources may be controlled precisely if the switching is accomplished using solid state electronic devices. The power transfer unit (PTU) allows power contractors to transfer power from a number of power sources (14, 14') in a controlled manner to minimize disruption at the load (12). The PTU utilizes a logic controlled electronic switch (24) in parallel with the contacts of a power control relay (10). The combination of an electronically controlled switch and an electromechanical relay provide precise switch timing with minimum power dissipation.

Abstract: In a phase lock loop circuit comprising a charge pump circuit (13), a loop filter (14), and a voltage controlled oscillator (15), a subsidiary loop filter (20) is connected to the charge pump circuit and the loop filter in a phase lock operation through first and second switching circuits (21) and (22). The loop filter comprises a filter capacitor (C1) and delivers a filtered signal to the voltage controlled oscillator. In the phase lock operation, the subsidiary loop filter reduces a charge duration and a discharge duration of the filter capacitor. As a result, a voltage of the filtered signal varies rapidly. For this reason, the phase lock operation is carried out in high speed.

Abstract: Process for making monolayer capacitors with a ferroelectric titanate-base layer as dielectric on a substrate, the ferroelectric layer being situated between a first and a second noble-metal electrode. The ferroelectric layer is produced in the form of a barium titanate layer having a layer thickness in the range from 0.2 to 0.6  mu m by applying a stable solution of salts of carboxylic acids, alkoxides and/or acetyl acetonates and decomposing them thermally at temperatures in the range from 500 to 700 DEG C. The concentration of the solution which forms the ferroelectric layer is adjusted so as to produce a titanium oxide excess of about 1 mol% after the thermal decomposition process. The coating process is repeated until the desired layer thickness has been reached, after which the second noble-metal electrode is applied to the ferroelectric layer.

Abstract: The discriminating sensitivity of a sense amplifier and the speed of the circuit are increased by exploiting the difference of potential which develops across the output nodes of the two control circuits, employed for enabling/disabling current paths of the input network of the differential amplifier, as a virtual additional signal for the sensing differential amplifier, by employing said output potentials of the two control circuits as virtual reference potentials for the pair of input transistors of the differential amplifier during a discriminating phase of the reading cycle. Two pass-transistors driven by a control signal provide to force to ground potential the output nodes of said control circuits, thus reestablishing a correct ground reference potential of the amplifier, during the final phase of amplification and storage of the extracted datum in an output latch, as well as during the successive standby period. Alternative embodiments also include various anti-overshoot circuits.
