Title: Friction material
Inventor: AIBA YASUHIRO
IPC: C04B35/52
Filed: 1989-03-13
Abstract: PURPOSE:To maintain a high coefficient of friction stable up to a high temperature region, even in the case of a fellow material made of steel, by constituting a material of respectively specific % by weight a steel fiber and/or steel whisker, bound carbon and the rest of an addition agent. CONSTITUTION:A friction material is constituted of by weight 10 to 70% steel fiber and/or steel whisker, 2 to 30% bound carbon and the rest of an addition agent. This bound carbon contains even carbon obtained by the CVD method in addition to carbon obtained by baking in the atmosphere of non-oxidation organic matter of various resins especially thermo-setting resin, coal system or petroleum system tar, pitches, etc. The bound carbon in the friction material generates its strength insufficient, when the amount of the carbon is less than 2%, and decreases a coefficient of friction when the amount exceeds 30%. An amount of steel fiber and/or steel whisker in a base material, when less than 10%, decreases the coefficient of friction and, when exceeding 70%, causes a problem of generating seizure with a fellow material. Thus by a combined effect of steel fiber and/or steel whisker and bound carbon, the high coefficient of friction is maintained even when a temperature increases of the steel-made fellow material.

Title: Speaker system
Inventor: SUDO JUSABURO
IPC: H04R1/30
Filed: 1989-03-13
Abstract: PURPOSE:To reduce the weight of a speaker unit without being accompanied with sound quality deterioration by suppressing vibration of a baffle body with the interference of sound energy outputted from a front face and a rear face of the speaker. CONSTITUTION:A sound energy from a speaker 5 is outputted in front from a front face horn section 3 at the front side of a communicating hole 2 and outputted toward the rear side from a rear face horn section 4 at the rear side. In this case, the sound energy outputted in front and the sound energy outputted to the rear side have equal to sound pressure and different phase by 180 deg., then the sound energy in the middle of the baffle body 1 made of a foamed styrol is cancelled with the interference and the middle part is not vibrated. Thus, the weight is made light without deterioration of sound quality.

Inventor: PAURU AADAMU
IPC: C06D5/06
Filed: 1995-02-14
Abstract: PURPOSE: To prevent the generation of high sound pressure when an opening is made in a sealing disc, by allowing a propellant acceptor to contain surplus substance which chemically, thermally acts on the surface of the sealing disc to generate a chemically reactive propellant gas continuously burning the sealing disc. CONSTITUTION: A propellant 8 in a combustion chamber 5 is ignited by an igniter of pyrotechnical type. A high temperature propellant gas 14 is generated by burning the propellant 8, and the pressure in the combustion chamber 5 is increased. An accepter of the propellant 8 is allowed to contain stoichiometrically excessive amount of oxidizer to generate a chemically reactive gas 14 by burning, and the gas functions as a welding flame. An interrupting film 11 holds a the combustion chamber 5 to remain closed until a stable burning process is produced in the combustion chamber 5. When the pressure becomes enough large, the interrupting film 11 springs off, and the high temperature propellant gas 14 from a blow-off hole 13 collides with the sealing disc 18. Thus, the sealing disc 18 ignites, and burns to open a discharge hole 19.
