Title: Acoustic device for vehicle
Inventor: MURAKAMI YOSHIAKI
IPC: B60R11/02
Filed: 1982-06-01
Abstract: PURPOSE:To perform reproduction at a necessary sound pressure level in a desired low frequency range to about 50Hz by making a hole with necessary area in a panel member, and supporting a diaphragm member at both opposite edges of the hole and confronting it to the hole. CONSTITUTION:The rectangular hole 8a with necessary area is formed in the panel member 8 at a driver arrangement position. The diaphragm member 9 made of a different material from the panel member 8 is supported fixedly at both lengthwise opposite edges of the hole 8a to face the opening part 8, and an exciting driver D is fitted nearly in the center of this diaphragm member 9. Namely, the driver D is supported in a beam shape on the panel member 8 by the rectangular diaphragm member 9. Concentrated mass added beam oscillation of two degree-of-freedom systems occurs to the diaphragm member 9, which generates sound pressure for low-frequency reproduction. In this case, the material, shape, size, etc., of the diaphragm member 9 are so selected that the lowest resonance frequency f0 (about 50Hz) is a desired frequency, so a sufficient output sound pressure level is obtained close to a desired low-frequency part of about 50Hz to improve the efficiency.

Title: Wire-cut machining device
Inventor: HAYASHI EIKICHI
IPC: B23K26/14
Filed: 1986-04-23
Abstract: PURPOSE:To check the extent of consumption in a feed fluid as well as to aim at improvement in machining efficiency, by installing a labyrinth groove on a surface to be opposed to a workpiece at a nozzle tip part, and rotating a nozzle centering on a medium's injection shaft. CONSTITUTION:A pulselike voltage is impressed on a gap between a wire 2 and a work 1 whereby this work 1 is fused, evaporated and scattered, thus machining is progressed. A dielectric fluid is spouted to the vicinity around the wire 2 from a feeder 4 via a nozzle 3. At this time, the nozzle provided with a labyrinth groove 11 is rotated at high speed by a motor 9. The dielectric fluid radially flowing out by way of a gap 12 in a two dimnetional manner is restrained from outflow by a labyrinth seal (shaft sealing) action. Therefore, the dielectric fludi is efficiently fed to a cutting groove 13, thus machining efficiency is improved.
