Title: Voice detection system
Inventor: AKAMINE MASAMI
IPC: G10L15/04
Filed: 1990-02-14
Abstract: PURPOSE:To reduce an omission and the addition of a noise by calculating feature parameters from a voice signal and projecting in a specific main component vector space, discriminating whether a voice signal is a voiceless or voiced sound according to the position of the projective point, and increasing voice/ voiceless-sound detection accuracy. CONSTITUTION:The voice signal is inputted and encoded by a voice encoder 41 and a noise encoder 42. One of the outputs of the encoders 41 and 42 is inputted to a cell generating circuit 46 through a selector 45 and made into a cell. The selector 45 is switched according to the discrimination result of a voiceless/voiced-sound discriminating device 43 and only the voiced section of the voice signal is made into the cell. A noise detector 44 detects only the voiceless sound section, wherein a background noise is encoded by the noise encoder 42. The selector 45 is switched to the side of the noise encoder 42 when the discriminating device 43 detects the voiceless sound. The device 43 calculates the LPC cepstrum C of the input voice signal to analyze the main component, an inner product calculator 51 finds the projection point Q of C, and the discriminating device 56 decides whether a frame is voiced or voiceless according to the Q.

Title: Recovery method for heat of waste gas
Inventor: YAMAMOTO MAKOTO
IPC: F28F13/00
Filed: 1982-03-02
Abstract: PURPOSE:To convert the form of heat transmission into the heat transmission of latent heat  based on the change of phase, and to improve thermal conductanc by moving the potential  heat of exhaust gas to steam as the latent heat of vaporization of water atomized and absorbing the potential heat to water flowed in from an inflow pipe as the latent heat of condensation by the condensation of the steam. CONSTITUTION:Exhaust gas from a diesel engine 1 is introduced into a heat exchanger 4, and water is atomized through a flow-rate regulating valve 11 from a water feed pipe 12 on its  midway. Water atomized is mixed into exhaust gas in a fog shape and vaporized by waste  heat of which exhaust gas at approximately 300-600 deg.C retains, and the temperature of exhaust gas drops to approximately 100 deg.C while relative temperature rises. With the quantity of water atomized, the flow-rate regulating valve 11 is adjusted properly, and the relative humidity of exhaust gas is adjusted to approximately 100%. A mixed fluid of exhuast gas and steam gas flows into the heat transfer pipe 13 of the heat exchanger 4. On the other hand, water at  a low temperature such as 50 deg.C flows into the heat exchanger 4 from the inflow pipe 5, and  exchanges heat indirectly with the mixed fluid flowing in the heat transfer pipe 13, and steam  in the mixed fluid is condensed. Accordingly, waste heat of which exhaust gas retains is recovered to water flowing in from the inflow pipe 5 in the form of the latent heat of condensation, and heated water flows out of an outflow pipe 6.

Title: Vertical magnetic recording and reproducing head
Inventor: YAGI MOTOI
IPC: G11B5/11
Filed: 1984-02-23
Abstract: PURPOSE:To eliminate the disturbance due to an induced magnetic field through offset compensation by detecting a magnetic field induced by an auxiliary magnetic pole or a main magnetic pole and driving a compensating coil with use of a detection signal to produce a magnetic field having the polarity opposite to said induced magnetic field. CONSTITUTION:A main magnetic pole 2 and an auxiliary magnetic pole 3 are provided, and a magnetic field detecting element 7 is attached to the lower end of the pole 3. The element 7 detects the upper and lower magnetic fields induced from outside to the pole 3. A compensating coil 8 is wound at a position peripheral to the pole 3. The polarity of the magnetic field generated by the coil 8 is set opposite to that of the induced field detected by the element 7. Thus the induced magnetic field is offset and has no disturbance. Generally the frequency of an external magnetic field is lower than the signal frequency of a record/reproduction mode. Thus an external induced magnetic field can be assuredly checked by means of an LPF10. This LPF is effective to the magnetic fields of low frequencies which occupy the greater part of induced magnetic fields.
