Title: Manufacture of semiconductor memory device
Inventor: SUZUKI TAKAAKI
IPC: H01L27/108
Filed: 1986-09-11
Abstract: PURPOSE:To simplify the process, by forming trenches, in which capacitors are formed, in a substrate, forming capacitor electrodes, forming trenches for isolation, which crosses the electrodes at a right angle, and filling the trenches with an insulating material. CONSTITUTION:Only a plurality of parallel trenches 20-1, in which capacitors are formed and which are extended in one direction, are formed on, the surface of a semiconductor substrate comprising, e.g., Si. Capacitor electrodes 23 such as poly Si layers are formed so as to face the surface of the trenches. Thereafter, a plurality of parallel trenches 20-2 are formed in the direction, which cross the electrodes at about a right angle. The trenches are filled with an insulating material 24-2 such as SiO2. Thus a step for etching and removing the SiO2, which is filled in the trenches having a large aspect ratio, can be omitted. Therefore, the process can be simplified.

Title: Manufacture of semiconductor device
Inventor: YOSHIDA MASAMICHI
IPC: H01L21/205
Filed: 1990-08-15
Abstract: PURPOSE:To eliminate a layer including boron at the interface between a Si substrate and a growth film and form a stable vapor growth film by causing fluorine to be adsorbed to the surface of Si wafer before vapor growth of Si and enabling polycrystalline growth or epitaxial growth of Si after heating the surface under the vacuum condition. CONSTITUTION:Boron is eliminated from the surface of a substrate by causing fluorine (F) atom to be adsorbed to the surface a Si substrate to which boron B is adsorbed through contact with the atmosphere. Namely, boron B adhering and adsorbed at the surface changes to BF3 by the reaction of B2O3+FH BF3+ H2O when a substrate is immersed into an extremely thin HF in addition to the conventional rinsing and moreover BF3 stably exists in the form of BF4<-> in HF. Almost all boron B is removed by the washing with water in the nest step. Moreover, BF3 which is in such a condition as to be removed easily can be removed from the Si substrate by heating the substrate up to 100 to 150 deg.C before vapor growth. With successive vapor growth, a layer including boron B is never left at the interface between the growth film and substrate. Thereby, characteristic of LSI may be stabilized and yield and reliability can also be improved.

Title: High frequency amplifier
Inventor: ITO KENJI
IPC: H01P5/08
Filed: 1987-08-28
Abstract: PURPOSE:To prevent deterioration or baking of MES FETs even when an excess voltage is impressed to an input terminal by constituting part or all the microstrip lines connecting the input terminal and the MES FETs by a superconduction material. CONSTITUTION:Part or all the strip conductors of microstrip lines 10, 5a connecting an input terminal 3 and the MES FET 6 is made of a superconduction conductor 12. The strip conductor made of the superconduction material has very minute insertion loss in the normal operating state. When an excess voltage is impressed to the input terminal 12, if a current flowing to a gate terminal 7 of the FET 6 exceeds the critical current of the superconduction material, the electric resistance of the conductor 12 is remarkably increased and the current flowing to the gate electrode does not exceed a critical current. The type of material of the superconduction material and the thickness of the conductor 12 are selected so as to bring the FET 6 not to be a value deteriorating the FET 6.

Title: Control system for synchronous motor
Inventor: ISHIDA HIROSHI
IPC: H02P27/04
Filed: 1982-12-08
Abstract: PURPOSE:To detect the position of a rotor by detecting the variation in the current flowed to a stator winding produced due to the difference of a magnetic permeability of the rotor. CONSTITUTION:Poles 10a, 10b, 10c, 10d of ferrite and intermediate units 11a, 11b, 11c, 11d of iron are alternately provided around a shaft 1a of a rotor 1. Since the magnetic permeabilities (u) of the poles 10a, 10b, 10c, 10d and the units 11a, 11b, 11c, 11d are different, the position of the rotor is detected by utilizing this difference. When the parts having different magnetic permeability exist, the currents iu, iv, iw vary in amplitude corresponding to the parts. The position of the rotor can be detected by detecting the phase phi of the position of the peak.

Title: Magnetic flux control type inverter
Inventor: ISHII SHINICHI
IPC: H02P23/07
Filed: 1988-08-31
Abstract: PURPOSE:To suppress the peak value of the output current of an inverter to a rated value or less by switching a calculated magnetic flux amplitude to a braking amplitude shocklessly by a slow-resetting calculator. CONSTITUTION:When a brake command is applied from a sequence processor 16, a comparator 15 compares a frequency set value from a setter 1 with a DC brake starting frequency from a setter 14. If an output frequency is the DC brake starting frequency or less, an AND gate 17 is opened to switch a switch 3, thereby moving a magnetic flux amplitude to a DC brake amount. A comparator 18 detects the substantially equality of the input to the output of a slow-resetting calculator 4 at the time of switching to inform it to a magnetic flux command calculator 5 to shut OFF its input side, thereby setting the output frequency to zero. The calculator 5 outputs a DC voltage from a measuring unit 13, and supplies a DC current to the armature of an induction motor 12 thereby to DC brake it, thereby decelerating its speed to stop it.

Title: Motional feedback system
Inventor: FUJIWARA NOBUO
IPC: H04R3/04
Filed: 1985-09-28
Abstract: PURPOSE:To attain the optimum compensation at every speaker by arranging a feedback compensating circuit at a speaker part. CONSTITUTION:A sound signal is inputted to a gain compensating circuit 12 in an amplifier unit 8 through an input terminal 1, and a gain compensation against the component at vicinity the low-pass threshold frequency of a speaker 6 is performed. An acceleration sensor 7 outputs a motional signal corresponding to the acceleration of a vibration plane on the speaker 6. A feed back compensating circuit 11 arranged at a speaker 10 applies a phase compensation on the motional signal and mixes it and signal eoc from the circuit 12 with a prescribed ratio, outputting it as signal eob. The signal eob is amplified at a gain compensating circuit 13 and an amplifier circuit 4, becoming a signal eoa and driving the speaker 6. Since the feedback compensation circuit 11 is arranged at the speaker part 10, the optimum compensation at every speaker can be obtained. Also, since the transmission distance of a weak motional signal is short, the deterioration of a S/N can be prevented.
