Abstract: PURPOSE:To obtain sound field characteristics in accordance with the sort of a source to be reproduced and listener's liking by converging an acoustic lens so that a direct wave from a speaker device can be listened on a listening position in a vehicle room and diverging the acoustic lens so that indirect sound can be listened on the listening position. CONSTITUTION:When the focus of a convergence type acoustic lens 1 is set up on the listening position on a front sheet, a response on the listening position is set up so that the level of indirect sound is smaller and the response is managed by direct sound. On the other hand, acoustic energy radiated from a speaker unit 3 is spread by a divergence type acoustic lens 2 and much reflected sound is generated by a reflection wall such as a front glass 5. Thereby a response on the listening position is managed by indirect sound including much reflected sound. The lenses 1, 2 can be automatically or mantually changed from the convergence type up to the devergence type by a BEF 12, a correlation circuit 13 and a control means 15. Consequently sound field characteristics can be changed in accordance with the sort of a source to be reproduced or listener's liking.

Title: Production of friction material
Inventor: SHIRAISHI HIDEO
IPC: C08J5/14
Filed: 1987-06-10
Abstract: PURPOSE:To obtain the title friction material having a stabilized quality and a reduced cost, by adhering a resin component to a woven fabric by spray coating during its weaving step, and applying heat and pressure to it after premolding. CONSTITUTION:In a process for producing a friction material by adhering a resin component to a woven fabric and applying heat and pressure to it after premolding, the purpose friction material is obtained by spraying said resin component to said woven fabric during its weaving step. The reason why the resin adhesion step is inserted in the weaving step of the woven fabric is that the need of immersing the finished woven fabric can be eliminated and therefore the instability of its textile can be eliminated. Further, the resin adhesion is performed not by immersing the woven fabric in a liquid resin diluted with a solvent but by spray coating, so that the resin concentration used need not be limited, and the measurement of the adhered resin can be easily made. Therefore, this process is markedly advantageous in quality and production cost.
