Title: Manufacture of semiconductor nonvolatile storage device
IPC: H01L27/115
Filed: 1992-03-17
Abstract: PURPOSE:To prevent the short-circuit between floating gate electrodes, by a method wherein a silicon oxide film is constituted in a gentle shape at the end portion of a first conducting film, by etching the first conducting film turning to a floating gate electrode in a direction, sticking a second conducting film on the sidewall, and then thermal oxidation is performed. CONSTITUTION:By anisotropic etching wherein etching rate difference between poly-silicon films 7 and 6 is used, only the poly-silicon film 7 is etched by the film thickness. As the result, a poly-silicon film 7a is left only on the sidewall part of the poly-silicon film 6. Next, e.g. by a thermal oxidation method, a poly-silicon films 8A turning to a second gate insulating film is formed on the poly-silicon film 6 and the poly-silicon film 7a, and further a poly-silicon film 9 turning to a control gate is formed on the whole surface. Since the poly- silicon film 7a is stuck on the sidewall of the poly-silicon film 6 and the sidewall is made gentle, etching residue is not generated when a floating electrode and a control electrode are patterned.

Title: Governor control for hydraulic power plant
Inventor: TSUKUDA YOSHIO
IPC: H02P9/04
Filed: 1982-04-06
Abstract: PURPOSE:To provide controllably approximately constant frequency of a water wheel generator by introducing signals responsive to water level in a surge tank into a governor. CONSTITUTION:A surge tank is provided in a water channel system, and a water wheel is controllably governed by a governor. Unless water level in the surge tank is varied, water level correction signals corresponding to said water level are not generated and the frequency fa of a water generator 5 equals a set frequency fr. When the water level is varied, rises and exceeds a reference value, a water level correction unit 103 sends the correction signal to an electric system governor amplifier 102 to reduce the set frequency value, and when the water level in the surge tank descends oppositely below the reference value, said unit 103 sends the correction signal to increase the set frequency value for correcting the set frequency value of the governor. Thus, even if substantial variation of the water level occurs, the frequency fa of the generator can be controllably equalized approximately to the reference frequency.

Title: Sound field processing circuit
Inventor: WATANABE KIMIHARU
IPC: H04S5/00
Filed: 1995-03-17
Abstract: PURPOSE: To make a spread sense of a surrounding sound and a reverberation sound compatible with a moving sense of the sounds by applying pseudo stereophonic processing to a Dolby surround signal having no surround information at frequencies below a specific frequency and applying monaural processing to the signal at frequencies over the specific frequency. CONSTITUTION: An input monaural signal is separated into a high frequency component, a medium frequency component and a low frequency component by an HPF 1, a BPF 2 and an LPF 3. A pseudo stereo processing circuit 4 receives the medium frequency component and converts the component into two signals with small correlation and provides the output of them. An adder circuit 5 adds the high frequency component, one output of the pseudo stereo processing circuit 4 and the low frequency component to obtain an output 1. An adder circuit 6 adds the high frequency component, the other output of the pseudo stereo processing circuit 4 and the low frequency component inverted by an inverting circuit 7 to obtain an output 2. A moving sound including many high frequency components remains a monaural signal, then a difference from a sound image is small even in the case of movement forward/backward. The surrounding sound and reverberation sound including many low frequency components have an extended stereophonic effect by the phase difference between the outputs 1 and 2 to intensity a spread sense.

Title: Surge absorbing element having safety mechanism
Inventor: KASAI YOSHITO
IPC: H01C7/12
Filed: 1992-02-12
Abstract: PURPOSE:To provide a flat and compact surge absorbing element by fixing a voltage non-linear resistance film, a discharge electrode film, and a heat generation resistance film to a surface of an insulation base board. CONSTITUTION:A surge absorbing element 2 having a safety mechanism is mounted on a printed circuit board of an electronic device. A surge of a rated value or more is applied from the outside through external terminal thin films 28, 30. Surge absorbtion is immediately started by a voltage non-linear resistance film 10. As a surge current quantity is increased, and when a voltage fall at the non-linear film 10 exceeds a discharge starting voltage between discharge electrode films 12, 14, a main arc discharge is generated in a discharge space 16 through a glow discharge, so a large surge is absorbed. A resistance film 18 generates heat to increase a resistance value quickly to increase a heat generation quantity synergetically. An insulation substrate 4 generates a thermal distortion to burst in a parallel direction to a leg part 24. Air flows into the discharge space, the discharge is eliminated, and supply of an overcurrent is cut off.

Title: Distribution line carrier receiver
IPC: H04B3/54
Filed: 1992-03-17
Abstract: PURPOSE:To provide the distribution line carrier receiver without a data error with respect to a load of a distribution line. CONSTITUTION:When a signal resulting from injecting transmission data '0', '1' corresponding respectively to two different orthogonal signals between lines of two of three-phase wire distribution lines is received, a 1st CT6a detects a signal from a single phase distribution line with the signal injected thereto, and a 2nd CT6b detects a signal from other single phase distribution line with the signal injected thereto The detection signals are respectively correlation- detected through a 1st BPF2a, a 1st correlation detector 3a and a 2nd BPF2b, a 2nd correlation detector 3b and the results are added by an adder circuit 4. Since the phases are deviated by 120 deg. with each other, a signal of any phase appears at a phase point avoiding the vicinity of a maximum or minimum value with respect to a power frequency, a peak level of an autocorrelation value being an output of the adder circuit 4 is not decreased thereby attaining data discrimination.
