Title: Permanent magnet motor
Inventor: NARITA KENJI
IPC: H02K29/00
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To utilize effectively magnet torque and reluctance torque in an inner- rotor permanent magnet motor. SOLUTION: A permanent magnet 11 with a bathtub-shaped cross section is used for each pole of a rotor core 10, and while a bottom part of the bathtub cross section is embedded toward a center hole 4, four permanent magnets 11 with the bathtub-shaped cross section are provided at intervals in the circumferential direction of the rotor core 10 in a way that each permanent magnet 11 are arranged with their adjoining poles opposite to each other. The permanent magnet 11 has a flux-barrier hole 14 at a position nearer to a q-axis on end faces (upper edge side of bathtub shape) for preventing leakage of magnetic flux or short circuit. A clamp part 12 is formed on a q-axis in a region between the permanent magnet 11 and the central hole 4, and a rivet 13 is passed on a d-axis in a region (c) between the permanent magnet 11 and the circumferential part of a rotor core 10.

Title: Ceramic board and manufacture thereof
Inventor: ITAKURA HIDEAKI
IPC: H05K1/02
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a ceramic board having a proper insulating property between conductive patterns, even if fine conductive patterns are formed on the board surface by a plating method. SOLUTION: In case fine conductive patterns having a distance of 50 μm between the conductive patterns are formed, an insulating property between the conductive patterns 20 can be prevented from becoming improper by forming a gap 12 at a roughened region 11 between the conductive patterns 20, even if conductive particles which have penetrated the roughened region during a non-electrolytic plating step remain at the roughened region between the conductive patterns during a soft etching step. Accordingly, even if fine conductive patterns are formed on the board surface by the plating method, a ceramic board having a proper insulating property between the conductive patterns can be obtained.  Additionally the gap 12 is formed by the laser irradiation beam of a YAG laser, therefore the required roughened region between the conductive patterns can easily and accurately be eliminated by choking a spot diameter of the laser.

Title: Neural network device
Inventor: IZUI YOSHIO
IPC: G06F15/18
Filed: 1990-02-07
Abstract: PURPOSE:To increase the learning speed to raise a probability of convergence to a globally optimum solution by calculating the total sum of feedback signals and independent signals by each neural element in a neural element group, and setting an aggregate to a minimum energy state while using the total sum value to change the output of the neural element with respect to probability. CONSTITUTION:Each neural element 11 in the neural element group calculates the total sum of feedback signals passing respective coupling element groups and independent signals which are inputted independently of these feedback signal and are practically equal to one another in each group. The calculated total sum value is used to change the output of the neural element 11 with respect to probability, thereby constituting the aggregate in the minimum energy state. Thus, a globally optimum solution is easily found and the convergence speed is increased.

Title: Vacuum degassing apparatus
Inventor: SOEDA TOMOMI
IPC: C21C7/10
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To dissolve the problem associated with the work using coarsely brocken bricks, to extend the service life of an apparatus used for a secondary refining and to obtain the stable refining by setting pre-cast blocks at least on the inner wall. SOLUTION: The alumina-made pre-cast blocks 1 and the magnesia-chrome- made pre-cast blocks 2 are manufactured and set on the inner walls of an upper vessel A, intermediate vessel B and lower vessel C in the apparatus. Heat-insulating castable refractory 3 is poured as back-up lining. The problem in the constructing method, the method, in which the coarsely broken bricks of the heat-insulating brick, alumina brick or magnesia-chrome brick are set at three or more layers and jointed with mortar, is the short service life because the wear at the joint parts caused by splash and powdery dust is remarkable. Further, in the large-sized apparatus, it is danger to execute the construction using coarsely brocken bricks particularly at the high place for a long time because of the high height, such as 7 meter or higher.  Furthermore, the construction of the small split bricks needs the long time causing the delay in the works thereafter. Therefore, such problems can be dissolved by applying the constructing method for setting the pre-cast refractories.

Title: Special reproducing system for vtr
Inventor: MIYASHITA YUKIMASA
IPC: H04N5/783
Filed: 1986-02-12
Abstract: PURPOSE:To obtain an output video signal having no noise, skew distortion and jitter by storing a reproducing video signal in a picture memory and outputting the data in a field interval corresponding to a special reproducing speed. CONSTITUTION:For instance during the reproduction of a still picture, if, when the first field of the first track is traced, a still picture mode is obtained, a servo circuit 11 traces the first field of the first track at an ordinary speed by the control signal from a system controller 12 and when it is completed, the circuit 11 is rewound slightly, stops and waits for the control signal of the next frame feed or an ordinary reproduction. At such a time, the reproducing video signal of the first field of the first track is stored in the picture memory 5 as the data. Since a memory controller does not rewrite the data of the memory 5 if the control signal for the frame feed or the ordinary reproduction does not come from the controller 12, the data of the first field of the first track is constantly outputted from an output buffer 6.

Title: Production of polyarylate
Inventor: HIROSE ISAMU
IPC: C08G63/19
Filed: 1989-02-07
Abstract: PURPOSE:To obtain a highly viscous polyarylate within a relatively short time by removing at least a half of the diphenyl ether from a specified mixture under reduced pressure at a specified point of time and adding diphenyl ether to the system. CONSTITUTION:A polyarylate is produced by heating a bisphenol diacetate and terephthalic acid or isophthalic acid or a mixture thereof to about 260 deg.C at normal pressure in the presence of diphenyl ether in such a way that at least 50wt.% of diphenyl ether is removed from the reaction mixture under reduced pressure for at least 2-9hr from the point of time when the temperature in the reaction vessel reaches about 260 deg.C. After diphenyl ether is added to the reaction mixture, it is heated at normal pressure to obtain a polyarylate of an inherent viscosity >=0.6dl/g. According to this process, the diphenyl ether is exchanged in the initial stage of the reaction, so that a highly viscous polyarylate can be produced within a relatively short reaction time.

Abstract: PURPOSE: To realize a linear electron beam microwave tube which features the cross-section inner side formed tetragonal with combination of the plate-type metal components and the eccentric collector opening along with the collector featuring the facilitated manufacture and reduced generation of the retrograde secondary electron.  
     CONSTITUTION: Collector 11 features the cross-section inner side formed tetragonal by the combination of the plate-type metal components; the plate-type component of upper surface 26 is installed obliquely to the tube axis;the collector opening through which electron beam 5 entering vertically to the tetragonal cross-section is made eccentric to the center of the cross-section. The tilt angle of upper surface 26 of collector 11 is set to 45° or less, and thus the high-speed electron travelling straight along the beam axis is reflected on surface 26 and then enters side surface 23 to be reflected upward of the horizontal surface. In this case, the reflection is repeated more than three times before going toward the lower part than the horizontal surface. As a result, the quantity of the secondary electron going back toward microwave circuit part along its energy can be reduced.
