Abstract: [Object] This invention provides a dispersion containing an insect pest repellent active substance, and an adhesive or bond, ink, resin pellets, a resin product, and a sheet or a film which can exhibit a long term repellent active effect by the particles carrying the dispersion.

Abstract: A table-type electronic percussion instrument is constructed by a table board, legs, pads as well as a musical tone generation circuit and a speaker system. Herein, the table board has a specific shape such as a pentagon-like shape which enables multiple persons to seat. The table board is supported by the legs and is constructed by a base material having a high rigidity and a dressing board like a plywood. The dressing board covers a surface of the base material through which holes are formed. The pads are arranged on a surface of the dressing board to match with locations of the holes. Sensors are provided inside of the holes and are attached to a backside of the dressing board. So, the sensors are arranged to detect striking force which is imparted to each of the pads by the persons. The musical tone generation circuit is provided beneath the table board to convert electric signals of the sensors to musical tone signals. The speaker system is located beneath the table board to generate musical tones (e.g.

Abstract: A hearth roller has an outer sleeve which constitutes a hearth roller barrel is disclosed. An inner sleeve is fitted into the outer sleeve and innermost sleeve is fitted into the inner sleeve. The ends of the inner sleeve in the axial direction are positioned inwardly and separated from each of the ends of the outer sleeve and are sealed by a metal. The inner sleeve has substantially the same linear expansion coefficient as the outer sleeve but exhibits higher thermal conductivity.

Abstract: A colored particulate material in the form of almost perfectly spherical fine particles comprising an organic and/or inorganic pigment coated with a hydrated metal compound over the surface thereof, the coated pigment being enclosed with an inorganic porous wall substance, process for producing the same, and a cosmetic composition comprising the same.

Abstract: An electric unit is powered by an external electric power source through a flexible wire plugged into a socket of the external electric power source, and the flexible wire is wound around a retractable winder after the flexible wire is pulled out, wherein the wire-winder is retracted into a space occupied by the electric unit so that the occupied space is decreased without impairment of the external appearance.

Abstract: An inorganic particulate material comprising fine balls approximately uniform in size and 0.1 to 50 .mu.m in mean particle size and prepared by admixing an aqueous solution of at least one compound (i) selected from among halides of alkaline earth metals, inorganic acids, organic acids, ammonium salts or inorganic acids, ammonium salts of organic acids and carbonates of alkali metals with an aqueous solution of at least one inorganic compound (ii) selected from among silicates, carbonates, phosphates or sulfates of alkali metals, halides of alkaline earth metals, and sulfates, hydrochlorides or nitrates of copper family elements o iron family elements before or after admixing an organic solvent (iii) with said aqueous solution of at least one inorganic compound (ii) to form a W/O emulsion, said compound (i) being capable of forming a water-insoluble precipitate when subjected to an aqueous solution reaction with said inorganic compound (ii).

Abstract: For detecting a difference in rendition, a bar incorporated in an electronic percussion system includes a supporting block having a surface portion, a top member having a first surface portion and a second surface portion located at the reverse side of the first surface portion, and a force sensitive unit intervening between the surface portion of the supporting block and the second surface portion of the top member and converting a force acting on the first surface portion into an electric signal, wherein the first surface portion is formed with a rugged surface which causes a striker to intermittently strike the first surface portion when the striker moves along the first surface portion.

Abstract: In the construction of a sound bar musical instrument such as a marimba, at least some of the sound bars have sensors attached thereto. The sensors are electrically connected to an electronic sound generator unit for generation of musical tones as a function of the vibration of battered sound bars, thereby allowing free use of a mallet and enabling visual contact of the performer with the audience.

Abstract: An electronic keyboard percussion instrument includes a hammer such as a mallet, a plurality of plates, striking detection devices, and a musical tone generating section. The plates respectively correspond to note names of musical tones to be produced and aligned parallel to each other. The striking detection devices are respectively mounted on lower surfaces of the plates to detect striking of the plate with the mallet and to generate a striking detection signal. The musical tone generating section generates a musical tone of the note name corresponding to the struck plate in response to the striking detection signal. The striking detecting section may include a pressure sensitive element in order to make the musical tone responsive to a force striking the plate.
