Title: Semiconductor device
Inventor: OKAMOTO YUTAKA
IPC: H01L21/8247
Filed: 1985-10-29
Abstract: PURPOSE:To provide preferable memory retaining characteristic and erasing characteristic by improving an insulating film applied on a floating gate to high quality to reduce a leakage current and to improve insulating dielectric voltage. CONSTITUTION:A floating gate 2 is formed of a single crystal semiconductor, the surface of the semiconductor is oxidized to form a second gate insulating film 3. Since a floating gate is recrystallized with a seed region having a smooth oblique taper by bird beaks of LOCOS when manufacturing the floating gate and particularly when recrystallizing it, its growth becomes uniform as compared with the case of vertical shape. As a result, since an insulating film of high quality obtained from the single crystal semiconductor is dense on the surface and has a film of high quality, a leakage current is small and excellent insulating dielectric voltage can be obtained.

Here, the mixer 6 alternately outputs a frequency f1 of a difference during the period in which the frequencies of the transmitting signal and the receiving signal both changes linearly and a frequency f2 of a difference during the period wherein the frequencies of the transmitting signal and the receiving signal are both constant. Then, a processing section 7 receives the signal with the frequency of f1 and the signal with the frequency of f2 to calculate the relative distance and velocity directly.

Abstract: PURPOSE:To prevent an air-fuel ratio from greatly fluctuating from a set value, by interrupting a feedback correction of the air-fuel ratio based on a integration processing when an output from an O2 sensor exceeds continuously a set value for discriminating an abnormal condition. CONSTITUTION:A comparator 32 compares an output from an O2 sensor applied thereto with a prescribed value. The output from the comparator 32 is subjected to the integration process by an integrator 30 as well as to the proportional process by a proportional amplifier 31 and the outputs from them are combined by an adder 33 to be an air-fuel ratio feedback control signal. On the other hand, the output from the O2 sensor is compared with the set values corresponding the maximum value and the minimum value and when it keeps the maximum value or the minimum value for a period linger than a prescribed period, an interruption signal is issued for closing a contact 34a and opening a contact 34b. As a result, the integrator 30 has a gain of zero and an output from the proportional amplifier 31 is not applied to the adder 33 for interrupting a feedback control of an air-fuel ratio.

Abstract: PURPOSE:To readily insert windings by providing a pair of insulating pieces disposed between the ends of two types of windings at both ends of a stator core and insulating foils made of nonparallel coupling legs connected between the pieces. CONSTITUTION:An insulating foil 10 formed of a resin film integrally has the first and second insulating pieces 11, 12 and at least two nonparallel coupling legs 13 for coupling the pieces 11, 12. After a main winding 21 is mounted as the first winding in a slot 20, the legs 13 of the foil 10 are inserted into the slot 20.

Abstract: PROBLEM TO BE SOLVED: To enhance fatigue characteristics, holding characteristics, rubbing characteristics and anti-stripping properties of a ferroelectric capacitor being formed by forming the upper electrode in oxidizing atmosphere. SOLUTION: A lower electrode layer 33 is formed on an SiO2 film 32 formed on an Si substrate 31.

Consequently, abstraction of O from the PLZT film 34 to the upper electrode layer 35 is suppressed on the interface between the PLZT film 34 and the upper electrode layer 35 and the upper electrode layer 35 is made compact 35.  As a result, residual dielectric polarization of the PLZT film 34 is maximized.
