Title: Diaphragm for speaker
Inventor: ONO TOSHIO
IPC: H04R7/02
Filed: 1988-06-02
Abstract: PURPOSE:To obtain a diaphragm for a speaker having an excellent frequency characteristic in a high frequency range by using carbon fiber plated with zinc, copper, or nickel and a mixedly woven textile composed of aromatic polyamide as the base materials of skin materials. CONSTITUTION:For a diaphragm 1 for the speaker, respective skin materials 3 and 4 are respectively adhered to the inside and the outside of a core material 2 composed of the honeycomb core of aluminum foil, and a three-layer sandwich structure is formed. For the respective skin materials 3 and 4, at least one of them uses the mixedly woven textile composed of a roving 5 as the aggregate of single yarn obtained by plating carbon fiber with zinc, copper, or nickel and a textile 6 obtained by plain-weaving aromatic polyamide as the base material, and the base material are impregnated with a resin, hardened by heating/ pressuring, and made into fiber reinforced plastics. Consequently, since the specific elastic modulus of the diaphragm 1 is high, the diaphragm 1 faithfully propagates the oscillation of a voice coil bobbin and has a moderate internal loss. Thus, a reflected oscillation from an edge can be absorbed, and the turbulence of the frequency characteristic in the high frequency range can be minimized.

Title: Ignition device
Inventor: SHIMOGATA TOMOHITO
IPC: F02P15/08
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To surely prevent the generation of knocking with a simple structure by providing an igniting means at different portions of the same combustion chamber of an internal combustion engine and changing an igniting position of the igniting means in the same combustion chamber at each cycle. SOLUTION: In a two-cylinder engine with ignition plugs, ignition plugs 3, 13 are fixed to the cylinder head 2 of one cylinder and are connected to a distributor 5 via a high tension cord 4. When the fuel-air mixture in a combustion chamber is ignited by the ignition plug 3 and a burning region A spreads from the left to the right to compress a region B unburned, a knocking N is generated in the region B unburned and increases temperatures rapidly and hence tends to produce a heat spot H there in the cylinder 1. Therefore, the ignition plug 13 is fixed to this spot H and ignites the fuel-air mixture in the next cycle to prevent an abnormal increase in temperature at the knocking spot, which prevents the knocking spot from being a heat spot.
