Title: Voice recognition device
Inventor: MATSUDA KAZUKI
IPC: G10L15/00
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To eliminate the deficiency of a voice recognition device that discrete word recognition that converts one word at a time has a poor operation efficiency and continuous word recognition that converts continuously inputted words in a batch requires a high performance MPU.

IPC: B22D11/16
Filed: 1991-11-27
Abstract: PURPOSE:To prevent the occurrence of a disturbance caused by a material adhering to a conductor so as to accurately measure the level of a molten metal in a mold by covering the external surface of a in-mold molten metal level detector with an insulating protective pipe having specific thicknesses.

Title: Agc circuit for fsk system optical direct amplifier repeater
Inventor: OGATA TAKAAKI
IPC: H04B10/07
Filed: 1990-11-30
Abstract: PURPOSE:To attain gain control with immunity from the effect of natural radiation light from an Er doped fiber by using an amplitude of a beat signal resulting from self-delay homodyne detection from an FSK modulation light as a reference signal so as to control a drive current of an excitation laser diode. CONSTITUTION:A light wave A is an FSK modulation light and its optical frequency changes as f1, f2 according to a data. A light wave B is delayed by 1 bit or over with respect to the light wave A and when the light waves A, B are synthesized and the result is subjected to photoelectric conversion, then a beat signal of f1-f2 is detected by square detection. When only the beat signal is extracted by a band pass filter 9 whose center frequency is f1-f2, a burst signal C is obtained and when the burst signal C is subjected to peak detection with a peak detection circuit 10 with a sufficiently small charge time constant and a sufficiently large discharge time constant, a peak signal D is obtained. Then a laser diode drive circuit 11 controls a drive current of an excitation laser diode 12 so that the peak signal D is always constant. Thus a problem that an output light intensity cannot simply be formed into a reference signal with a natural radiation light from an Er doped fiber is avoided.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce costs by utilizing the light projecting and receiving part of a safety switch, and setting and reading automatic door control information using a portable setter. SOLUTION: During periods other than door closure control, a circuit 10 for sending and receiving control information is connected to the light projecting and receiving part 7a of a safety switch to make possible the transmission and reception of the control information. Then when a command signal related to settings of the control information is sent from a setter 11 to a light receiver 9, an answer signal generator 10a issues an answer signal such as speech to inform a commander of the reception. Then, after the contents of the command are written in a control information storage part 3, the contents of the settings are transmitted to the setter 11 using the light projector 8 of the safety switch for a check. Then an opening/closing control part 2 controls a door engine 4 based on the information set in the storage part 3, to control the opening and closing of a door 5.  Thus the control information can be managed through remote control without addition of an input/output interference to the automatic door side, and costs can be reduced.

Title: Water head difference filtration device
Inventor: EGUCHI TAMIYUKI
IPC: B01D61/14
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent empty suction pumping or the excessive increase of filtration pressure by having an inlet for filtrate at a lower position than the liquid level of a liquid to be filtered, installing a storage vessel having a communicated passage with the atmosphere and providing a means for properly discharging the filtrate in the storage vessel. SOLUTION: Both of a membrane module 1 and the storage vessel 2 of the filtrate are dipped into a vessel 3 housing the liquid to be filtered and the membrane module 1 is installed at the lower position than the liquid level 7 of the liquid to be filtered. A filtrate line 4 is connected to the storage vessel 2 of the filtrate at a lower position than the liquid level 7. The communicated line 6 with the atmosphere, which is projected on the water level 7 from the storage vessel 2, opened to the atmosphere at the tip and makes water head difference between the liquid level 7 of the liquid to be filtered and the filtrate line 4 and the filtration is carried out by the water head difference.  When the height of liquid level 7 reached equal to or below the filtration lien 4, the filtration is spontaneously stopped and even if a suction pump 8 is worked, the empty suction or the excessive increase of the filtration pressure is not generated. As a result, the whole device is simplified to be economical.
