Title: Speech recognition device
Inventor: NAGAISHI MICHIHIRO
IPC: G10L15/24
Filed: 1989-10-13
Abstract: PURPOSE:To obtain a high recognition rate even when recognition is hardly performed with only information in voice by judging totally both the information in voice and information on the shape of lips in sound generation at the time of speech recognition and predicting the generated voice. CONSTITUTION:The voice is gathered by a voice input means 1 and A/D- converted after noise processing, and then converted into an electric signal. The converted voice signal is supplied to a voice analyzing means 2 to take a signal analysis by items of a frequency, intensity, etc., thereby obtaining data required for the recognition. An image input means 3, on the other hand, inputs the shape of the mouth and lips as an image together with the voice and records it in the form of an electric signal and a feature extracting means 4 analyzes and extracts data to be referred to at the time of the voice recognition from the image data according to the recorded image information. A speech recognizing means 5 judges the data totally to decide whether or not what is the target voice and the result is displayed by a display means 6 to the user. Consequently, even when the recognition is hardly performed with only the data in voice, the speech recognition device which has a high recognition rate is obtained.

Title: Method for operating float melting device
Inventor: KOBAYASHI HIROAKI
IPC: F27B14/06
Filed: 1994-11-01
Abstract: PURPOSE: To enable a fast melting of small pieces to be carried out and to be integral with a melting part by a method wherein a feeding of small pieces is carried out intermittently at an initial stage of a melting step and an electrical power when the small pieces are fed is set to be lower than a normal electrical power by a predetermined rate. CONSTITUTION: High frequency voltage is applied to a dielectric coil 2 wound at an outer diameter part of a crucible 1 comprised of an upper crucible 11 and a lower crucible 12, and some small pieces 53 are continuously fed onto a melting part 51 of melted product 5 through an upper opening of the crucible 1 by a continuous feeding device 3. When the small pieces 53 are fed, an applying electrical power is set to be low against a normal electrical power and a lateral adjusting force is reduced to make a shape of the melting part 51 flat. An area for receiving small pieces 53 is increased through this flat shape and a possibility in which some small pieces 53 are displaced out of the melting part 51 is reduced.  In addition, when the electrical power is returned back to the normal electrical power, the melting part 51 is changed from the flat shape to a longitudinal shape, the small pieces 53 pierced into the melting part 51 are fallen and a contact surface with the melting part 51 is increased.

Title: Continuous high speed rolling method
Inventor: KUSAMA MAKOTO
IPC: B21B31/07
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To prolong the life of bearings by cooling the specific part of the outside wheel of bearing in the roll chock of a rolling mill. SOLUTION: With a rolling load applied to the lower roll by means of the lower roll chock 6a of a rolling mill, a part θ of the rollers 8 inside the lower roll chock 6a is brought into contact rotatably with the inside wheel 9 of the bearings, which causes heat and a high temp. through friction and the stirring resistance of a lubricant; also, with a plastic deformation occurring by the rolling load, sticking takes place in the rollers and the inside/outside wheels of the bearings. On the other hand, in the non-contacting part of the rollers 8 in the inside wheel 9, little heat is caused, showing a low temp. compared with the part θ.  Accordingly, by cooling only the outside wheel 7 inside the lower roll chock 6a in the area where the plastic deformation of the rollers 8 occurs, only the rollers 8 are cooled that are in contact rotatably with the outside wheel 7 in a high temp. so as to prevent plastic deformation; simultaneously, by minimizing the temp. difference between the non-contacting part of the inside wheel 9 and the outside wheel 7, a thermal deformation is eliminated on the entire circumference of the outside wheel 7, so that rolling is performed while a clearance 10 is maintained for a set clearance between the rollers 8 and the inside wheel 9 of the bearings.
