Title: Small-sized combustion apparatus for low grade coal
Inventor: TANIGUCHI HIROSHI
IPC: F23B30/08
Filed: 1982-02-23
Abstract: PURPOSE:To make the residence time of low grade coal on a moving grate longer so as to make the ignition easy and allow the combustion to be completed, by slanting the grate so that the latter stage of the movement of the coal is elevated, and providing coal supply means at the intermediate section. CONSTITUTION:The inclination theta of a moving grate 20 is set at 30-60 deg. and the position (B) of a coal supply port 23 is spaced 1/2A-2/3A away from a coal stopper 22. If the conditions become in the state where ignition is possible, low grade coal is supplied onto the grate 20. The coal is first moved in the direction toward the coal stopper 22, and then is carried upward with the intially supplied coal forming a lower layer under the subsequently supplied coal layer due to the movement of the grate 20, during which the combustion continues. In this case ridges 20a facilitate to deliver the coal upward.

Title: Trunk line channel fault monitoring system
Inventor: KAWANA KAZUO
IPC: H04M3/22
Filed: 1980-03-04
Abstract: PURPOSE:To find a fault on a channel rapidly by discriminating the fault state of the channel by detecting the potential difference between two conductors constituting the channel and by displaying the fault while blocking the trunk of the trunk line when the fault is occurring. CONSTITUTION:The potential difference between two conductors A and B constituting the channel 1 is detected by differential amplifier AMP, whose output voltage is compared to prescribed potential by the 1st and 2nd comparators COMP1 and COMP2. If the short circuit or interruption of the channel of the trunk line occurs, the potential difference between the conductors decreases below normal one, which can be detected by the 1st comparator COMP1. The 2nd comparator COMP2 can detect the polarity inversion of the channel of the trunk line, but if a call signal does not arrive in a constant time, a fault signal is outputted via a time monitoring circuit and the 1st comparator COMP1 generates an output only when the fault signal output is not generated.

Title: Voice input recognizing device
Inventor: MATSUMOTO YOSHIYUKI
IPC: G06Q40/02
Filed: 1991-02-21
Abstract: PURPOSE:To execute voice recognition in a short period and with high accuracy by discriminating a keyword waveform from an inputted voice waveform, and recognizing an effective voice from the voice waveform in the vicinity of the keyword waveform. CONSTITUTION:In a RAM 28 of a voice processing part 2, voice waveforms of 'Yen' and 'shees' are stored as keyword waveforms in advance. A sub-CPU 24 discriminates whether the keyword waveform is contained in the waveform inputted from a microphone 20 and stored in a voice waveform storage part 29 or not. When it is contained, the waveform immediately before its waveform is recognized as an effective voice waveform by a voice recognizing part 25. In such a way, a noise waveform can be eliminated, and the voice recognition of high accuracy can be executed in a short period.

Abstract: PURPOSE:To exactly measure an electromagnetic field around an apparatus by connecting a connecting line formed on the surface of a printed board to the earth through characteristic impedances of the connecting line and taking out a voltage between both terminals. CONSTITUTION:The connecting line 1 is formed on the surface of circuit board 2, both surfaces of which are formed to the earth surfaces, and both sides of the line are terminated to the earth on rear side with the characteristic impedances (terminal resistors) of approximately 50OMEGA for the board 2; e.g., from the terminal resistor 4b, the voltage of both terminals is taken out by a coaxial cable 5. The voltage taken out through the cable 5 has a directivity. That is, the electric field has the directivity in which the sensitivity becomes maximum (minimum) for an electromagnetic field from the plus (minus) direction of X-axis. Thereby, the incoming direction of electromagnetic field can be found out by a sensor for adjacent electromagnetic field, and the feature of electromagnetic field distribution can be obtained in vectorwise. Also, a reproducibility of the measurement is maintained since an impedance dismatching of the electromagnetic field sensor and cable 5 can be lessened.
