Inventor: TO IGUN
IPC: G06F17/30
Filed: 1999-12-10
Abstract: PROBLEM TO BE SOLVED: To retrieve a Chinese compound word according to a part of a character, to display the compound word, and to narrow them down more properly. SOLUTION: When an operator draws parts in a 1st KANJI (Chinese character) part input area C1 and a 3rd KANJI part input area C3 of a 1st KANJI input area W1 with a mouse and presses the right button of the mouse in a 2nd KANJI input area W2 (RbD), a 1st KANJI candidate shown in the figure is obtained, a 'Chinese compound word consisting of two characters' is retrieves, and the retrieval result is displayed in a compound word candidate display area Wx. Thus, compound word candidates are retrieved by using as keys the number of character constituting the compound word, at least one character candidate, and the order of the character candidate, so a more proper narrowing-down process is performed.  Further, since the character candidate is retrieved according to a part of the character, not the whole character but only character parts are inputted to make it possible to retrieve and input the Chinese compound word.

Title: Rotary application method/device
Inventor: KAMISHIRO KENZO
IPC: H01L21/027
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of a semiconductor wafer and resist. SOLUTION: An air nozzle 41 is shifted and air is flowed from the blow-off port in a state where the semiconductor wafer 1 is rotated before resist is dropped on the semiconductor wafer 1. Thus, air blow is made on the whole face of the semiconductor wafer 1 and resist is dropped. Not only foreign matters on the semiconductor wafer 1 but also foreign matters entered a recess on the semiconductor wafer 1 float with an air blow and they are blown to the outside of an area on the semiconductor wafer centrifugal force with rotation. Thus, the foreign matters on the semiconductor wafer 1 can securely be removed. Consequently, adhesion between resist and the semiconductor wafer 1 can be improved.

Title: Signal processing method for radar apparatus
Inventor: HONDA KANAKO
IPC: G01S7/292
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To miniaturize a radar apparatus and to enhance its accuracy. SOLUTION: In a radar apparatus of an FM-CW system, a beat signal is frequency-converted by an FFT circuit 40. A signal processing circuit 44 first finds distribution of the signal level of the beat signal with reference to a frequency and to a measuring angle, by using the frequency component of the beat signal obtained in every period of every increase period and every decrease period. The signal level Lp and the frequency fp of the maximum point of a curved surface which expresses the distribution of every period as well as the central angle θm and the angle width Δθa of an angle range are found as variables of data on the maximum point. In addition, data on maximum points in both periods are compared. The combination of the maximum points in which the difference between the variables is less than a reference value is found.  On the basis of the data on the maximum points, the relative distance between a target and the radar apparatus and their relative speed as well as the position and the size of the target are found. As a result, the position and the size of the target can be found without narrowing the beam width of transmitting waves.

Abstract: PURPOSE:To improve the denseness of sintered Si3N4 by sintering a compact containing Si3N4 powder in an inert gas atmosphere at a temperature higher than a prescribed temperature and lowering the temperature to the prescribed temperature at a specific cooling rate. CONSTITUTION:A slurry is prepared by adding and mixing 5-15wt.% of an oxide sintering assistant and/or a nitride sintering assistant such as MgO and AlN and a water-based binder to Si3N4 powder having particle diameter of <=2mum. Granules prepared from the slurry are press-compacted and the produced compact is coated with powder having similar composition, put into a graphite vessel and inserted into a sintering furnace. The compact is heated at 900 deg.C or thereabout in vacuum to eliminate the binder and sintered by maintaining in N2 gas atmosphere at >=1600 deg.C for a prescribed period. The sintered product is cooled to 1600 deg.C at a cooling rate of 45-50 deg.C/h (when the wall thickness of the molding is <=15mm), 10-45 deg.C/h (when the thickness is 15-30mm) or 5-10 deg.C/h (when the thickness is 30-50mm).

Title: R-fe-b permanent magnet being excellent in electrical insulating properties, heat resistance and corrosion resistance and manufacture thereof
Inventor: SUZUKI MASAKO
IPC: C23C14/12
Filed: 1995-12-25
Abstract: PURPOSE: To obtain a permanent magnet for an automobile being excellent in electrical insulating properties, heat resistance and corrosion resistance by providing a polyimide film of a specified film thickness on the surface of an R-Fe-B permanent magnet body of which the main phase is constituted of tetragonal crystals, with a ground metal film of a specified film thickness interlaid. CONSTITUTION: A polyimide film of a film thickness 2.0-10μm is provided on the surface of an R-Fe-B permanent magnet body of which the main phase is constituted of tetragonal crystals, with a ground metal film of a film thickness 1.0-3.0μm interlaid. The reason why the thickness of a ground metal provided on the cleaned surface of a magnet is limited to 1.0-3.0μm is that the thickness less than 1.0μm and that exceeding 3.0μm are both undesirable since the former is insufficient for the adhesion to the surface of the magnet and the latter causes a rise in the cost as the ground film.  The reason why the thickness of polyimide resin is limited to 2.0-10μm is that the thickness less than 2.0μm and that exceeding 10μm are both undesirable since the former makes it impossible to obtain a film being excellent in electrical insulating properties, heat resistance and corrosion resistance and the latters causes a rise in the cost of manufacture.

Abstract: PURPOSE: To improve magnetic field uniformity and a fill factor on nuclear magnetic resonance spectroscopy(NMR) by reducing a diameter of a sample tube outside an observation region to a diameter according to a shape sectioned as a rotating solid. CONSTITUTION: A sample tube is formed to completely include a sample in a volume which is symmetrical with respect to a z-axis line 28 and substantially symmetrical with respect to an intermediate plane 27. It is formed by a tube to minimize discontinuity of a liquid column and its end is like a cone of a rotating body which gradually varies. A diameter 24 of the tube is increased so that the maximum fill factor can be obtained. When an end of the tube is made to be spherical, the minimum amount of sample is required, but discontinuity in magnetic susceptibility occurs closer to an edge of an observation region than any other rotating body shapes. Existence of a sufficient amount of sample can be obtained by one of shapes of an end which stretches a region with susceptibility discontinuous to a sufficient distance from the observation region.
