Title: Oriented material
Inventor: HAZAMA KAZUHIKO
IPC: C08F220/18
Filed: 1990-03-29
Abstract: PURPOSE:To enhance transparency, moisture absorptive dimensional stability and mechanical strength by regulating orientation release stress (ORS) in the biaxial both directions to a specified range in the biaxially oriented material made of specified methacryl-based copolymer resin. CONSTITUTION:In a film or a sheetlike biaxially oriented material made of methacryl-based copolymer resin which is constituted of 95 - 40 wt.% methyl methacrylate unit and 5 - 60 wt.% cyclohexyl methacrylate and has <= 12 g/10 min melt flow index, ORS in the biaxial both directions is regulated to a range within 3 - 30 kg/cm<2>. When the amount of methyl methacrylate unit exceeds 95%, improvement of moisture absorption is made insufficient. When the same is less than 40%, transparency and weather resistance are deteriorated. When the amount of cyclohexyl methacrylate unit is less than 5%, improvement of water absorption is made insufficient. When the said amount exceeds 60%, mechanical strength and weather resistance are deteriorated. When the melt flow index is made excessively large, entanglement between molecules is weakened and the brittleness improving effect due to orientation is deteriorated. When ORS is less than 3 kg/cm<2>, the orientated material is easily broken during handling. When ORS exceeds 30 kg/cm<2>, tear strength is weakened.

Title: Voice detector
Inventor: SASAKI SEIJI
IPC: G10L25/00
Filed: 1991-03-28
Abstract: PURPOSE:To detect whether or not there is a voice in a short process time while a delay time is suppressed to <=7 msec by outputting a voiced/voiceless flag which indicates a voiced or voiceless state. CONSTITUTION:Prediction coefficients a1 and a2 are, inputted to and framed by framing units 31 and 32 at intervals of 5msec, and supplied to mean value calculators 33 and 34. The mean value calculators 33 and 34 calculate and input mean values of one frame to a voiced/voiceless state decision unit 35. The decision unit 35 sets the voice detection flag (u) to the voicelss state when the mean value of the prediction coefficients a1 and a2 is within a specific threshold range or to the voiced state when not. A hangover processor 36 performs a 100msec hangover process for the obtained result to obtain a final voice detection output (v). Consequently, the required processing time for voice detection processing is reduced to about 5msec or made short and the detector is realized with small-scale hardware.
