Title: Target tracking apparatus
Inventor: KISHIMOTO TAKUYA
IPC: G01S13/50
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a target tracking apparatus which eliminates erroneous judgment and which can track a target continuously, by a method wherein, when the irregularity in an observation Doppler frequency is large, a designated target judgment Doppler frequency existence width is made large. SOLUTION: A received video signal obtained by being transmitted to, and received from, a target by a radar device 2 is collected as target information by a signal processing part 3. A designated target judgment Doppler frequency existence width computing part 8 by a standard deviation computes a designated target judgment Doppler frequency existence width on the basis of the standard deviation between a designated target Doppler frequency existence width from a remote instruction device 7 and observation Doppler frequencies in (n) numbers of times in the past. Then, a designated target judgment part 4 by a Doppler frequency difference judges a designated target 1 contained in the designated target judgment Doppler frequency existence width.  At this time, the computing part 8 makes the designated target judgment Doppler frequency existence width large (or small) when the irregularity in the observation Doppler frequency is large (or small). As a result, a detected target does not exceed the existence range of the Doppler frequency of the designated target, and an erroneous judgment in which targets other than the designated target are judged as a target is eliminated.

Title: Manufacture of diaphragm-system pressure sensor
IPC: G01L9/00
Filed: 1992-03-30
Abstract: PURPOSE:To realize a diaphragm-system pressure sensor which can be integrated as a circuit by a method wherein a high-energy ion-implantation method is adopted, dopants are introduced into an Si substrate up to an etching stop condition and an etching operation is performed. CONSTITUTION:A single-crystal Si substrate 1 is used as a target; B ions are implanted at 1012 keV; the concentration of the implanted ions is increased as the depth from the surface becomes deep; the concentration reaches its peak at a depth of about 2mum and is dropped sharply in a deeper part. Consequently, when a high-energy ion implantation operation is executed and the single-crystal Si substrate 1 is then etched from the rear side of an ion-implanted face, it is possible to obtain a diaphragm 2 whose thickness is, e.g. about 2.1mum. In the ion implantation method, the concentration of dopants can be computed accurately. As a result, the thickness of the diaphragm 2 can be controlled accurately and easily. In addition, since the concentration of the dopants in the surface layer of the single-crystal Si substrate 1 can be made low, the diaphragm can be integrated as a circuit on the Si substrate.

Title: Speech recognition device
Inventor: TOKUDA TADAMICHI
IPC: G10L15/06
Filed: 1993-03-31
Abstract: PURPOSE:To correspond the speech recognition device which uses a neural network as a recognition part to aging variation in the pronunciation of a speaker with time by letting a neural network part learn speech feature data which causes misrecognition in case of misrecognition. CONSTITUTION:The neural network 3 incorporated in the speech recognition device learns the speech feature data which causes misrecognition automatically at each occasion under the control of a speech recognition and learning control part 7. In order to prevent defective data from being learnt, the learning is performed only when the speech feature data match data which are already learnt to some extent. Therefore, even if the pronunciation of the speaker varies with time, the speech feature data are learnt at each time to adapt the device to the variation in the pronunciation of the speaker, thereby maintaining high recognition precision.

IPC: B03C3/41
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent the rescattering of dust particles from a dust collecting electrode and to make the cleaning of the dust collecting electrode easy in an electrical precipitator for air purification. SOLUTION: DC high voltage V is applied between a dust collecting electrode 11 and counter electrodes 13, 15 to collect charged dust particles on the dust collecting electrode 11. The dust collecting electrode 11 is formed of a metal net to form an unequal field near the surfaces of the dust collecting electrode. The smaller a radius R of the net wire of the metal net is, the better. It is desirable that a distance L between the adjoining net wires is sufficiently narrow so that there may exist no clearance in which the unequal electric field is not formed. Practically, it is preferable that R<=0.1mm, and L/R=2∼4. Furthermore, the surface of the dust collecting electrode 11 is covered with a thin insulating film to make the shape of the surface smooth.  It is preferable that the insulating film has volumetric resistance of >=10<8> Ωm and its specific inductive capacity is smaller than that of the electrode material and is <=10. The thickness of the insulating film is made equal to or smaller than the radius of the net wire. Instead of the metal net, a metal plate provided with a lot of projecting parts and slits and a printed circuit board having lattice-shaped printed wiring may be used.

A judging means 2a calculates the number of different pixels at corresponding positions of both blocks and judges that the blocks are the same or similar when the number of different pixels is less than a specific value to generate a moving vector V. The judging means 2a also judges whether or not the moving vector V is used by divided block, and judges that the blocks are the same or similar when the number of differences between both the blocks is less than a specified number to perform motion compensation by using the moving vector V of the macroblocks. Reverse algorithm is used for decoding.

Filed: 1995-03-31
Abstract: PURPOSE: To lower a change in magnetic attraction force which is caused by a field magnet and works on an end face in the movement direction of a movable yoke and prevent cogging torque from appearing and thereby obtain smooth thrust of the movable member by bending an end in the movement direction of the movable yoke away from the field magnet of a stator.

In this motor, an end 711 in the movement direction of a yoke 71 of the movable member is bent- formed. With this end 711, the distance between the yoke 71 and the field magnet 61 is made longer and thereby a change in magnetic attraction force which is caused by the field magnet 61 and works on an end face in the movement direction of the yoke 61 of the movable member is decreased. By this method, cogging torque is prevented from appearing and smooth thrust of the movable member can be obtained.

Abstract: PURPOSE:To improve the capacity of compressor by forming a coated layer on the outercircumference of a roller having a vane incorporated in a oval volume cylinder thereby avoiding metallic contact between the roller and cylinder and reducing the gap at the contact point. CONSTITUTION:A roller 5 coupled to a drive shaft 3 is mounted rotatably on an oval volume cylinder 4. Many vanes 8 are contained retreatably in the roller 5 and contacting slidably with the inner face of the cylinder 4.

CONSTITUTION: When a front body part 1a is rotationally moved setting a contact point 0 as a fulcrum, a screw conveyor 2 is displaced by a bent angle θ. Next, stroke quantities in the horizontal direction of right and left respective parts of a front body 1a against a rear body 1b are measured with stroke meters 10, and input to a computer. Next, a moved quantity to be difference of right and left strokes is computed by the computer and input to a bent angle converter, and the stroke moved quantity is converted to the bent angle θ by the bent angle converter. Further the converter 2 is horizontally displaced rotationally movably by a hydraulic jack 7 so as to approach to the bent angle θas the target value. According to desire, the conveyor 2 is almost similarly controlled in the horizontal and vertical directions.  Hereby, the position can be automatically corrected, correctly and quickly.
