Title: Power generating method utilizing waste gas energy produced from electric furnace and heating furnace for rolling steel
Inventor: FUJISAWA YUTAKA
IPC: F01K27/02
Filed: 1980-04-24
Abstract: PURPOSE: To attain an effective utilization of thermal energy by a method wherein hot waste gas produced at an electric furnace is passed through a waste heat boiler to produce steam, and at the same time the generated steam is reheated by utilizing the waste heat of a rolling furnace for steel to generate electric power by driving a steam turbine.  
     CONSTITUTION: Hot gas from the steel making electric furnace 10 is guided to a combustion chamber 14. Upon complete combustion, the hot gas is fed to the waste heat boiler 15. Mediate pressure steam produced at the waste heat boiler 15 is heated again through an independent over-heater 17 processing a hot waste gas form the rolling heater furnace 16, overheated, then an electric power is generated through a condenser turbine 18. When one unit of electric furnace 10 is applied, a part of the waste gas with alow temperature is corrected for its decreasing temperature with a heater source such as a burner and the like, and in turn when a plurality of units of electric furnaces 10 are applied, a gas temperature is adjustes in response to an operation of the number of units installed, then it is fed to the waste heat boiler 15.

Title: Momentary interruption detecting circuit
Inventor: YAMANE HIROMITSU
IPC: H04Q3/42
Filed: 1989-03-09
Abstract: PURPOSE:To facilitate the analysis of a cause when speech is interrupted suddenly by allowing a momentary interruption detection section to monitor the state of lines SS and SR and sending it to a momentary interruption storage section when the momentary interruption is detected to hold it. CONSTITUTION:When a momentary interruption takes place in a line SS 24 leading to a transmission line after speech is established, an output of an AND gate 33 of a momentary interruption detection section changes to a low level to reset a momentary interruption latch section FF 34 at that point of time. Thus, the monitor signal goes to a low level at that point of time and its state is held. In this case, although a FF 26 is triggered, the state is not changed from the set state. Even when a momentary interruption takes place in an SR line 25 leading from the transmission line after speech is established, an output of the AND gate 33 changes to a low level and the FF 34 is reset at that point of time. Thus, the monitor signal goes to a low level at that point of time and its state is held.

IPC: G01B11/00
Filed: 1993-02-19
Abstract: PURPOSE:To set an original point accurately with little labor by minimizing the evaluation values on the basis of the center of gravity for middle points of common perpendiculars to the directional straight line of a camera taking a certain point at the center of the field in plural positions and postures and the distances to respective middle points. CONSTITUTION:An approximate original point of a robot camera is set by use of a level or the like. Then, a certain point is taken at the center of the field of the camera in plural camera postures. The middle points of common perpendiculars to the directional straight line of the camera are obtained in respective postures. The centers of gravity and the distances to respective middle points are evaluated and then minimized. That is, the original point is corrected so that the simple sum or the sum of squares, of the distances, will be a minimum. In this case, the accuracy may be enhanced, as follows; to average the error in job preparation and mechanical error of movable shaft, the process is made in setting plural fixed points and thus the respective original points obtained are averaged. Accordingly, the work of setting the original point by used of such as a level is simplified. And the original point is set accurately without the influence by installational error and dimensional error.

Title: Prescaler ic
Inventor: ISHII HIDEKAZU
IPC: H03B19/14
Filed: 1990-03-06
Abstract: PURPOSE:To enable operations over a wide frequency range while making a signal amplitude correspond to an operational frequency band by switching an operational current corresponding to the operational frequency band, simultaneously switching load resistance as well and changing an amplification factor. CONSTITUTION:When a power supply voltage is impressed to a control terminal C1, a current flows through a bias resistor RB to a transistor Tr28. As a result, the current flows to current source transistors Tr29 and Tr31 as well. Namely, the operational current of an FF circuit is increased. Further, since transistors Tr19, Tr20, Tr21 and Tr22 are turned on as well, for the load resistor, respectively paired load resistors RL1 and RL5, RL2 and RL6, RL3 and RL7 and RL4 and RL8 are respectively made parallel. Therefore, even when the operational current of the FF circuit is increased, the signal amplitude can be reversely reduced.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To improve a recognition ratio by judging an expression corresponding to a hidden Markov model(HMM) for calculating maximum generation probability out of plural HMMs as a recognition result. SOLUTION: In the constitution of each HMM, states corresponding to the number N of states are named like S1 to SN successively from the left. The S1 is called as an initial state, the S2 to SN-1 are intermediate states and the SN is called as a final state. In the HMM, the probability of each state is updated in accordance with an output value (corresponding to a feature vector) and the probability of the final state at the end of an output string is defined as the generation probability of the output string. Fourier transform is applied to respective components of a speed vector calculated from an inputted face moving image and a feature vector string corresponding to the movement of expression is extracted from Fourier transform coefficients. The HMM is previously prepared by learning in each expression category of an object to be recognized.  An expression category corresponding to the HMM in which the calculated generation probability is maximized is judged as a recognition result.
