Title: Fuel vaporizing device
Inventor: NAGATA KATSUYA
IPC: F23D11/44
Filed: 1990-09-13
Abstract: PURPOSE:To perform uniform and complete vaporization of fuel and to provide a high volume ratio and vaporizing efficiency by a method wherein a vaporizing pipe is filled with porous sheets having at least one ventilating hole. CONSTITUTION:A vaporizing pipe 3 is filled with a plurality of sheets 10 having a ventilating hole 9 extending through the vaporizing pipe 3 to upper and down stream parts such that the porous sheets are laminated in a manner to partition the upper and down stream parts in the vaporizing pipe 3. Preheated air flows through a feed port 1 to the vaporizing pipe 3. Meanwhile, fuel is fed through a tip feed port 17a of a fuel feed pipe 17 toward the outer peripheral surface of the porous sheet 10. The fuel orderly permeates the porous sheet 10 and oozes through the inner peripheral surface of the ventilating hole 9, and is vaporized during the passage of preheated air through the ventilating hole 9. This constitution enables uniform and complete vaporization of fuel gas and provides a high volume ratio and vaporization efficiency. Further, fuel gas can be uniformly mixed.

Title: Thickness measuring device
Inventor: HIRAGA TATSU
IPC: G01B15/02
Filed: 1988-09-29
Abstract: PURPOSE:To accurately measure board thickness by setting a time for measuring a leading edge part(leading edge part non-including time (x)), outputting the raw data of measured value every reference counting time from starting measurement till attaining the leading edge part non-including time+average operation time and performing average operation with moving average when the leading edge part non- including time passes and the average operation time is attained. CONSTITUTION:In a measurement mode, the change of the radiation dose which occurs by shielding a radiation ray 3 radiated from a beam source container 2 with the aid of a sheet steel is fetched as an output signal from a radiation ray detector 5. The signal is amplified by an amplifier 6 and the amplified signal is, moreover, converted into a digital signal by an A/D converter 7. An arithmetic processing device 8 calculates the board thickness from the digital signal. In such a case, from starting the measurement till attaining the leading edge part non-including time+average operation time, the raw data of the measured value of the board thickness of every reference counting time is outputted. When the leading edge part non-including time passes and the average operation time is attained, the average operation is performed with the moving average to obtain the board thickness and calculate the deviation from the board thickness which is to be obtained. Thus, the sheet steel having accurate board thickness can be obtained.

Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To maintain the controllability of a vehicle satisfactorily by enabling the amount of operation of the steering wheel of a vehicle to be switched over between a state where it is decreased and a state where it is increased and, after the state is switched over from the state where it is increased to the state where it is decreased, maintaining the state for a specified time. SOLUTION: While a tractor is being operated, a controller 19 judges whether or not a front wheel steering speed is over a set value, a lift arm angle is over a set value, a transmission position is at a low speed position, and a PTO selector switch 51 is turned on. When all the judgments are yes, the solenoid 45 of a selective control valve is energized to switch over the valve to a state where the amount of operation of front wheels is large. In addition, it is judged whether or not a front wheel position is returned to a straight forward are and, when the front wheels are returned to the straight forward area, the solenoid 45 is deenergized to switch over it to a state where the amount of operation of the front wheels is decreased.  In this case, when the solenoid 45 is deenergized, a flow is interrupted by a timer for a specified time so that a course adjustment can be made easily during the interruption.
