Abstract: PROBLEM TO BE SOLVED: To stabilize oscillation wavelength of a laser diode module to be constant, by controlling the temperature of a laser diode on the basis of ratio of detected result of an optical output detecting means and detected result of a wavelength detecting means. SOLUTION: A part of the optical signal passing a line monitor 13 is electrically converted with a photodiode in a wavelength monitor 25 and inputted in a comparator 27. Output from the line monitor 13 also is inputted in the comparator 27. Intensity ratio of the two signals is detected, and the wavelength of present optical output from a laser diode module 5 is detected from the detected value. When difference exsists between the wavelength of present optical output and the wavelength of originally set optical output, a control signal is outputted to a temperature control circuit 11, and oscillation wavelength is corrected.  That is, the temperature control circuit 11 so controls a temperature control element 9 that difference between the wavelength of present optical output and the wavelength of originally set optical output is eliminated, and controls the temperature of a laser diode element in the laser diode module 5.

Title: Pressure detection method
Inventor: SHIJI RYOZO
IPC: G01L7/00
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To determine the height of fluidized bed accurately by blowing gas into a fluidized bed furnace and measuring the back pressure thereof so that the inner pressure of the fludized bed furnace can be measured accurately thereby detecting the differential pressure accurately. SOLUTION: Refuse and silica sand are fed through a refuse/fluid medium supply pipe 2 into a fluidized bed furnace while the air is blown out through an air introduction pipe 5 and combustible refuse is burnt. Furthermore, compressed air is blown out through air jet pipes 6, 16. Consequently, back pressure of same level as the jetting pressure of compressed air is generated in back pressure detection pipes 9, 19. Inner pressure at the forward end of the jet pipes 16 can be detected by means of a pressure gauge 23. Differential back pressure between the back pressure detection pipes 9, 19 represents the pressure difference between upper and lower positions which is proportional to the height of fluidized bed.  Consequently, the height of fluidized bed can be determined by measuring the differential back pressure between the back pressure detection pipes 9, 19 with differential pressure gage 10 and performing a theoretical calculation based on the differential pressure through an appropriate arithmetic unit.

Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a control method for synchronous motors wherein when a synchronous motor is controlled by a hybrid amplifier system thrust steps produced at a point of control switching are corrected. SOLUTION: The control method for synchronous motors is for driving a synchronous motor provided with a position detecting means 7 for detecting the position of the synchronous motor 5, a control means 1 that controls the synchronous motor according to a current command, a switching means that switches between a linear control amplifier and a PWM control amplifier according to a thrust command, and a power circuit 4 that accommodates both controls.  In the control method, actual current is measured in advance with the points of switch between the linear control and the PWM control and a current command at the time of maximum current taken as measurement points within the entire current control range, based on current commands as measurement points, and a correction gain is calculated for correcting the gain error between an ideal current based on a current command and an actual current by linear interpolation. The synchronous motor is driven by a corrected current command obtained by multiplying the current command by the correction gain, thereby reducing thrust ripples and steps in thrust at the time of switching the hybrid amplifiers.
