Abstract: PURPOSE:To improve the dielectric strength of high delectric strength elements by forming small signal elements and high dielectric strength elements on one substrate and eliminating the self- dosing action in double epitaxial layers. CONSTITUTION:An N<+> epitaxial layer 4 is made on a p type Si substrate 1 and is deposited with an (n) epitaxial layer 4. An N<+> buried layer 6 and a p<+> deposition layer 11 are made on the layer 4, and are deposited with an n- layer 7. Next, with the surface oxide film 8 as a mask, the layer 7 is etched and the layer 4 on the layer 3 is slightly scraped to selectively create recesses 9. An oxide film 10 is newly formed over the entire surface, and p<+> isolating layers 18 are made through stretching and diffusion from the P<+> layer 11, connecting to (p) layer 1. Next, a high dielectric strength element having p<+> base 12, n<+> emitter n<+> collector lead-out part 14 is provided in the layer 4 on the buried layer 3, and a small signal element having p<+> base 15, n<+> emitter 16, n<+> collector lead-out part 17 is created in the layer 7 on the buried layer 6 in an ordinary manner, after which Al wirings are formed to complete the device. In this method, the interfaces of the layers 4, 7 have been selectively removed and therefore the impurity layers by self-dosing may be removed, then uniform epitaxial layer formed and the high dielection strength element formed.

Title: Insulated-gate type semiconductor device
Inventor: KUMAGAI NAOKI
IPC: H01L29/78
Filed: 1992-05-01
Abstract: PURPOSE:To achieve an insulated-gate type semiconductor device that requires a low gate driving energy and induces a low switching loss at a low ON-state voltage by the use of a current absorbing means disposed on an epitaxial layer by way of an insulation film. CONSTITUTION:A gate terminal 12 connected with a first gate electrode 6 is connected to an output terminal of a normal gate driving circuit 19, and a second gate terminal 14 connected with a second gate electrode 7 is connected to a positive potential side of a driving circuit power supply 18. The second gate electrode 7 is therefore connected to a source electrode 9 in the manner of an alternating current. The majority of a potential current occurring at the time of switching is bypassed to the source electrode 9 in a regulated manner, and hence it becomes possible to suppress a displacement current that flows through the gate electrode 6. Therefore, variations in a voltage between the gate and the source are not hindered, and gate displacements vary in a short period, whereby it is possible for an element to achieve a low driving energy and a low switching loss.

Title: Receiver for multi-carrier system
Inventor: SASAKI MITSURU
IPC: H04J11/00
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To conduct stable automatic frequency control with a wide lock range by detecting a phase change of one optional carrier in a multi-carrier so as to obtain frequency deviation thereby reducing the effect of multi-path and fading. SOLUTION: An automatic frequency section 30 detects a phase change in one optional carrier obtained by an FFT and eliminates a modulation component from the detected phase change and a modulation elimination section 32 detects fluctuation in a local oscillator. The modulation elimination section 32 discriminates at which quadrant a reception symbol is in existence. The rotated reception symbol represents a phase shift of a carrier on the Y axis, Thus, the frequency is controlled by feeding back the frequency to the local oscillator so that the phase shift in the carrier is eliminated. Then a statistic processing section 33 averages a phase shift of the carrier from which a modulation signal is eliminated and on the occurrence of multi-path in the object carrier, the adverse effect is reduced. Then a feedback variable control section 34 conducts the feedback control proportional to a magnitude of the phase shift of the carrier from which the modulation signal is eliminated.

Abstract: PURPOSE:To improve the control precision for air-fuel ratio by avoiding the influence of the vibration of an engine power train system by correcting the correction value for fuel quantity on the basis of the signal of the engine revolution speed, besides the conventional load signal such as the opening degree of a throttle. CONSTITUTION:A control circuit 10 calculates the fundamental injection quantity on the basis of the signals of a revolution speed sensor 8 and an intake pressure sensor 5. Then, the air-fuel ratio is judged by the signal of an air-fuel ratio sensor 7.
