Title: Speaker diaphragm
Inventor: YAMAMOTO TOORU
IPC: H04R7/02
Filed: 1982-10-19
Abstract: PURPOSE:To attain a high specific modulus and high rigidity for a speaker diaphragm without lowering internal loss by using the base material of thermoplastic resin such as polypropylene, etc. together with the reinforcement material of mica and flaky graphite. CONSTITUTION:The base material of 75wt% polypropylene is used, and the reinforcement material of 22wt% flaky graphite and 3wt% mica is added to the base material. These base material and the reinforcement material are well kneaded by a diaxial screw extruder to obtain a master pellet. The preliminary drying is applied to the master pellet for 10hr and at 110 deg.C, and then a composite sheet of 160mum thickness is sheeted from a T die by means of a uniaxial screw extruder. This composite sheet is heated about 7-8sec by far infrared rays, and a vacuum molded at the softening time point. It is observed that the diaphragm using such composite sheet reduces a frequency characteristic and distortion and increase the band of reproduction. A1-A3 exemplify a sound pressure characteristics in case of single mica and graphite, and B1-B3 exemplify the distortion characteristic in case of the same state respectively.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To improve the coking resistance and carburization resistance of a reaction pipe in a pyrolysis oven for preparation of ethylene. SOLUTION: This reaction pipe comprises a high Ni-Cr-base heat-resistant alloy comprising 1.5 to 4 wt.% Si and/or 1 to 4 wt.% Al, wherein the inner surface of the pipe is coated with an SiO2 film, an Al2 O3 film, or a composite film of SiO2 and Al2 O3 . The film is formed by heating and holding the inner space of the pipe at a temperature of about 700 deg.C or above in a vacuum atmosphere of not more than 10<-4> Torr or in an atmosphere regulated to a partial pressure oxygen equivalent to the vacuum atmosphere of 10<-4> Torr. Preferential oxidation of Si and/or Al in the pipe material results in the deposition of an SiO2 film or an Al2 O3 film. The Sin, film inhibits coking of the inner surface of the pipe, and Al2 O3 functions as a barrier for inhibiting carburization in the inside of the pipe wall. The film has high adhesion and can stably maintain its effect.
