Title: Electron emitting element and its manufacture
Inventor: KUMOMI HIDEYA
IPC: H01J9/02
Filed: 1987-12-06
Abstract: PURPOSE:To improve the conductivity of an electrode by forming electrode for electron emission by using a mono-crystal having a specific plane azimuth and having a point surrounded by a facet consisting of specific crystal surfaces. CONSTITUTION:A formed Si mono-crystal 504 has a facet consisting of a crystal surface 507 of higher order between {111} surfaces 506, {311} surfaces, and {411} surfaces each in four planes and is formed from a point 505 from four triangular surfaces. As the facet surface 507 is a crystal surface, the crest of this point 505 has a sharpness at atomic level theoretically. The mono-crystal 504 installed on this base 501 is used as an electrode for electron emission, and a pullout electrode is provided near this electrode for electron emission. This prevents dispersion of the shapes of electrode having point 505 as the electron emitting part and improves its performance.

Title: Method for regenerating column for liquid chromatography
Inventor: EIKI YOSHIHIRO
IPC: B01D15/08
Filed: 1989-11-28
Abstract: PURPOSE:To improve the performance of a deteriorated column by washing a column packing material, substituting the inside of the column with an org. solvent which dissolves a salt and washing the column with an org. solvent in which amine having pKa higher than the pKa of an amino group is dissolved to remove the amine. CONSTITUTION:The column packing material to be regenerated is washed with the aq. soln. prepd. by dissolving the salt which dissolves in the org. solvent and contains negative ions of a large ion radius, for example, sodium perchlorate. The column is then substd. with the org. solvent which dissolves the salt, for example, acetonitrile. This column is washed with the org. solvent prepd. by dissolving the amine which has the pKa higher than the pKa of the amino group and can be washed by the org. solvent, for example, triethyl amine; thereafter, the amine is removed by the org. solvent. Perchlorine ions and hydrophobic adsorbed materials are removed in this way and the materials adsorbed on the HPLC column are removed, by which the performance of the deteriorated column is efficiently improved.

Title: Power transmission device for inboard/outboard motor
Inventor: ITO HIROSHI
IPC: B63H23/06
Filed: 1986-12-26
Abstract: PURPOSE:To avoid the occurrence of excessive running resistance and obtain a large tilt-up angle for a propulsive casing by providing an acceleration/ deceleration changeover device at the connection of an input shaft and an intermediate shaft, and positioning said device aft of the intersection of said shafts in a propulsive direction. CONSTITUTION:A normal/reverse changeover device 25 is built into the lower part of a propulsive casing 16 and an acceleration/deceleration changeover device 20 built into the upper part thereof. It follows, therefore, that the connection part of an intermediate shaft 23 and a propeller shaft 26 in the immersed part of the casing 16 contains only the normal/reverse changeover device 25, thereby avoiding an increase in projected area in a propulsive direction and an excessive increase in running resistance. Also, the upper part of the propulsive casing 16 comes to house the acceleration/deceleration changeover device 20 only aft of the intersection of an input shaft 19 and the intermediate shaft 23. Consequently, the top of the casing 16 bulges upward only in a range aft of the intersection of the input shaft 19 and the intermediate shaft 23. Therefore, the range of a tilt-up angle can be enlarged, thereby preventing the top of the casing 16 from interfering with a hull.

Title: Pretreatment method for electroless plating
Inventor: OGASAWARA SHUICHI
IPC: C23C18/18
Filed: 1993-12-09
Abstract: PURPOSE:To provide a method for formation of a metal layer by electroless plating on the surface only of the circuit formed on a board using a board obtained by heat treatment after a metal layer formed on a polyimide resin surface by non-electroless plating or by, first, electroplating and, next, electroplating. CONSTITUTION:After a circuit has been formed by patterning the metal layer of a board, the board surface is treated by a treatment solution containing hypochlorous acid, and a catalyzer is given to the circuit and polyimide resin surface. Then, the catalyzer-absorbed polyimide resin is eluted, and then a metal layer is formed on the circuit surface by electroless plating. Consequently, as a metal layer can be formed only on the surface of the circuit after it is formed by an electroless plating method even when a board is used, the electronic part such as TAB, FPC and the like, having multifunction and a high reliability, can be obtained.

Title: Device for generating musical sound
Inventor: JINBO TERUO
IPC: G10H1/057
Filed: 1993-12-10
Abstract: PURPOSE:To reduce the number of pitch envelope channels less than the number of DCO channels and to efficiently use the DCO channel related to a technique allocating a pitch envelope in a musical sound generation device. CONSTITUTION:The maximum number of pitch envelope channels is set less than the maximum number of DCO channels. When a new note on is generated, in a step 802, the number of using pitch envelopes and the number of using DCOs of a tone color related to the new note on are obtained from the tone color data stored in a ROM, etc. Then, in the case of the tone color requiring no pitch envelope, no control processes for assigning the pitch envelope channels shown in steps 803-806 are executed, and only the control processes for assigning the DCO channels after a step 807 are executed. Thus, the number of DCO channels assignable simultaneously is made more than the maximum number of pitch envelope channels.

Filed: 1989-11-29
Abstract: PURPOSE:To strengthen the state of engaging to the stopper body of a rubber stopper, and to prevent the slip-off of an injection needle completely even by the deflection of the rubber stopper at the time of the sticking of the injection needle by providing a section corresponding to the annular recessed groove of the rubber stopper with a means making air in the annular recessed groove escape to a top face or a side surface at the time of the injection molding of a lower stopper and injection-molding the lower stopper. CONSTITUTION:When a stopper body 4 is manufactured, an upper stopper 1 is injection- molded previously, a rubber stopper 2 is mounted on the upper stopper 1, and a lower stopper 3 is injection-molded, but an annular recessed groove 5 is shaped and pinhole sections 9 are formed to sections corresponding to the score 7 of the upper stopper 1 in the rubber stopper 2. The pinhole sections 9 are formed by shaping a large number of pinholes by a laser from the top face side or foaming at least the sections of the rubber stopper 2. When the lower stopper 3 is injection-molded from the lower side, air in the annular recessed groove 5 escapes to the top face, particularly the inside of the score 7 of the rubber stopper 2 from the pinhole sections 9 at pressure injected into the annular recessed groove 5 of the rubber stopper 2 of a molten resin, thus completely filling the inside of the annular recessed groove 5 with the molten resin.
