Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a device which can simplify the structure of its optical system, can improve its image resolution and also can accurately grasp the changing state of a tunnel wall surface from its developed image. SOLUTION: A developed image creation device fetches the split line data from a line sensor camera in every prescribed timing while moving in a tunnel, shifts every pixel from a position set on a virtual image forming surface to a position set on the tunnel wall surface in regard to the fetched split line data to decide a position space after the above shift and corrects the pixel space of the split line data according to the position space. In other words, (f, Vk) set on the virtual image forming surface is converted into (Xk, Yk) set on the tunnel wall surface, a space is decided between (Xk, Yk) and (Xk+1, Yk+1) and the pixel space is corrected from the decided space.  As this creation device produces a developed image after the pixel space is corrected, the width, length, etc., of the changing state of the tunnel wall surface which are measured from the developed image are accurately reflected on the actual width, length, etc., of the changing state of the tunnel wall surface.

Title: Timer position controlling apparatus for fuel injection pump
Inventor: MATSUMOTO SHINICHI
IPC: F02D41/40
Filed: 1982-12-10
Abstract: PURPOSE:To set a timer mechanism at a target position, by executing a process for judging stable idling conditions of an engine, a process for storing actual-position data obtained by a timer position sensor as a learnt value, and a process for correcting the learnt value. CONSTITUTION:A control circuit 8 has an input buffer 9 at the input side, an output buffer 10 at the output side, and an MPU11, a ROM12 and a RAM13 at its middle section. In case that it is judged that the idling operation is stable, a timer piston 59 is moved to the right-side end by fully opening a timer control valve 6 and leaking oil in a high-pressure oil chamber 60 of a timer mechanism 58 into a low-pressure oil chamber 61. The mean value of a predetermined number of input data is calculated by taking out the output signal of a timer position sensor 7 and the learnt value obtained from the calculation is stored in the RAM13. When the idling operation becomes unstable, datum-position data is calculated from a data map of the datum timer position using engine-speed data and load data as parameters, and the timer mechanism is set at a target position by calculating the duty ratio of a pulse having a prescribed frequency from the data relating to the target timer position and the data relating to its actual position.

Title: Treating device for exhaust gas from arc furnace
Inventor: NIWA YUKIO
IPC: F27D13/00
Filed: 1988-08-31
Abstract: PURPOSE:To efficiently treat the exhaust gas from an arc furnace by a method wherein a sub-system is provided in which the upstream side of a scrap pre- heating facility is connected to an arc furnace through a combustion tower, the down stream side is connected to a cooling tower through a deodorizing tower, and the exhaust gas from the sub-system is joined to a main suction line by an auxiliary sucking fan. CONSTITUTION:In a sub-system, the upstream side of a scrap pre-heating facility 42 is connected to an arc furnace 11 through a combustion tower 41, and the down stream side is connected to a cooling tower 44 through a deodorizing tower 43. The exhaust gas from the sub-system is sucked by an auxiliary sucking fan 45 located on the downstream side of the tower 44 and joined to the exhaust gas in a main suction line 21. As the gas flow rate in the sub-system is rather small in comparison with that of the main suction line but the pipe friction is rather high, the installation of the auxiliary sucking fan 45 to suck the exhaust gas from the sub-system reduces the required pressure of a main induced draft fan 31 so that the exhaust gas generated by the arc furnace can be adequately and effectively utilized as a whole and treated efficiently.
