摘要： PURPOSE:To improve the performance of the diaphragm for the speaker. CONSTITUTION:A coating film 5 is applied integrally to a major side of a diaphragm shell 1, an edge 2 and a gasket 3 being components of the diaphragm. Since the coating film is integrally coated at least to the major side of the components of the diaphragm in this way, water-resistance and moisture resistance are provided to each component and then the bonding strength of each component is improved and a minimum resonance frequency is enhanced.

摘要： PROBLEM TO BE SOLVED: To improve the physical property as a speaker, to increase the adhesive strength and to form diversified characters or patterns on a diaphragm by vapor-depositting a metal or a metallic compound onto part or entirety of the surface of a base of the diaphragm so as to laminate a vapor-deposition layer thereon. SOLUTION: A base 2 for the speaker diaphragm 1 is made of a plastic material consisting mainly of a pulypropylene and a metal or a metallic compound is vaport-depositted onto part or all of a surface of the base 2 of the diaphragm to form a vapor-deposition layer. Thus, diversified characters or patterns or the like are expressed onto the diaphragm 1 making up of a cone diaphragm and a center cap or the like. Furthermore, the diaphragm 1 forms a double layer consisting of the base 2 and the vapor-deposition layer 3, since the stiffness is enhanced and the internal loss is increased, the performance as a speaker is improved. Moreover, since the diaphragm 1 is made of the base with water-proof performance and the vapor-deposition layer, the water- proof performance is maintained. Moreover, ease of sure adhesion is obtained.

摘要： PURPOSE:To improve not only the performance of each component but also the performance of the combinations of the components. CONSTITUTION:A habutae textile used for a base material for the diaphragm of the speaker and various components ancillary to the diaphragm is featured that difference from the strength of threads is not caused and the textile is easily formed and hardly deformed. Furthermore, for example, rubber coating 13 is applied to the base material 12 to make the weight light (the weight is less than 25% of a rubber edge) while its external appearance is like the rubber edge and the forming time is very short. Moreover, a sheet material such as elastomer or urethane or a foamed coating material used to coat the base material has flexibility and is excellent in water-resistance, heat-resistance and weather-proof. Since the light weight, the shape maintenance performance, flexibility, water-proof, heat-resistance and weather-proof are attained by using the material as above for the diaphragm for the speaker and various components ancillary to the diaphragm, not only each performance of each component is enhanced but also the performance by combinations of them is improved.

摘要： PURPOSE:To allow a robot with a small memory capacity to attain complicated actions quickly with high accuracy by operating the robot based on point data obtained from the function and parameter of the route of a CP(Continuous Path)action which are stored while an index table is rotating. CONSTITUTION:Functions are inputted to a RAM 11c through the operation of a key on a keyboard 12. A function expressing an arc from a point P1 to a point P2, for instance, its center and radium, and parameters such as a distance between the points P1 and P2 which is equally divided into plural parts are stored through a robot controller 11. A rotor main body 15 is CP-operated according to the point data, which is operated based on the previously stored function and parameter while the index table 14 rotates by one station, and stored in the RAM 11c. Thus the robot main body 15 can mark smoothly and quickly at high accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a disk holder in which disks such as CD can be easily handled and the packaging material cost can the reduced. SOLUTION: A protection part 11 covering the information-recorded face of a disk 8 and a holder 12 fitting to the center hole of the disk to keep the disk 8 are integrally molded with nonwoven cloth in the disk holder 1 in order to hold the disk 8 such as CD, DVD, etc., in which information such as music or programs is recorded on at least either front face or rear face. The disk can be removed by only pushing the holder 12 and hence, the holder is easily handled and since it is integrally molded by a press, the cost can be reduced.
