Title: Carbon support for semiconductor manufacturing equipment
Inventor: HAMASHIMA HISAYUKI
IPC: C01B31/02
Filed: 1993-06-22
Abstract: PURPOSE:To obtain semiconductor products high in yield always through an epitaxial growth process and a plasma etching process by a method wherein a semiconductor support is formed of glassy carbon specified in quality. CONSTITUTION:A semiconductor support is formed of glassy carbon material which has such constitutional and purity properties that a specific gravity is more than 1.47, pores smaller than 20mum in size are contained, porosity is less than 5%, total ash content is less than 5ppm, and sulfur content is less than 10ppm. A structure higher than 1.47 in specific gravity is small is pore content and high in structural density, so that these structural properties enable the structure to be relaxed in degree of wear and tear and lessened in discharge of soot when pares are exposed. On the other hand, a structure has such purity properties that total ash content is less than 5ppm and sulfur content is less than 10ppm, and these purity properties restrain a wafer from being contaminated with impurities so as not to deteriorate a semiconductor device in performance if soot is produced. These structural and purity properties are required to be satisfied.

Title: Signal detection system
Inventor: TAKEUCHI YASUSHI
IPC: H04B17/309
Filed: 1984-08-24
Abstract: PURPOSE:To obtain the signal detection system which does not malfunction even in the presence of a noise by arranging an HPF which separates an information signal and a tone signal for circuit monitoring. CONSTITUTION:A speech signal and tone signal of single frequency f0 for circuit monitoring which is outside the frequency band of the speech signal and near its upper limit are inputted to a buffer amplifier 1. The output signal of the amplifier 1 is inputted to a PLL4 through an HPF4. The cutoff frequency of the HPF4 is in the middle between a speech band and the toner signal frequency f0 and the frequency characteristic is steep. Even if only a noise is inputted, a specific frequency component only appears in the output of the HPF4 and a frequency component of a passing band is outputted while superposed, so the S/N of the component of f0 and other components is low and a PLL does not acquires the f0.
