Title: Combustion device for pulverized coal and its operation
Inventor: OKIURA KUNIO
IPC: F23K3/02
Filed: 1989-03-02
Abstract: PURPOSE:To reduce the amount of use of an auxiliary fuel and improve the stability in ignition and make it possible to operate safely under a medium load for a boiler by the operation in which an auxiliary fuel is used down to the minimum load where pulverized coal can be exclusively burnt but a main burner of pulverized coal is ignited by an ignition torch of pulverized coal under higher loads. CONSTITUTION:A mill 30C is supplied with coal and the produced pulverized coal is supplied to a main burner 32 via a main fuel line 31. The main burner 32, because it has already a stable flame by an auxiliary fuel, is ignited completely and at the same time the fuel is supplied to an ignition torch 33 used for a burner 32' that is provided at a position one step higher than said burner 32 by a pulverized coal line 34 for an ignition torch from said mill, and the torch 33 is ignited by electric ignition means. Next, when coal is supplied to a mill 30B, the main burner at the second step from the bottom step and the ignition torch at the third step from the bottom step are ignited because the line 34' ts supplied to the burner at the one step higher step. With this arrangement the main burner 32'' at the topmost step is ignited when coal is thrown into a mill 30A.

Title: Electrostatic image developing method
Inventor: HOSOYA MASAHIRO
IPC: G03G13/08
Filed: 1983-03-29
Abstract: PURPOSE:To obtain a sharp developed image with a less toner scatter at the circumference of an image part and high resolution by using a single-component developer which has specific mean grain size as a developer. CONSTITUTION:The developer is scattered by the operation of an electric field produced between a developer carrier and an electrostatic image holder by a static charge on the surface of the electrostatic image holder to make an electrostatic image visible. In this case, the single-component developer which has <=10mum mean grain size is used. The mass of each toner particle is reduced by decreasing the grain size of the toner, so conventional resin is used as it is and no influence is exerted upon fixing performance, etc. The mass of every toner particle becomes less when the mean grain size of the toner is 10mum, so internal force F2 decreases. Therefore, the direction of resultant force operating on flying toner approximates the direction of a line of electric force and the track of flying toner particles is close to the shape of the line of electric force. Consequently, the arrival point of the toner on an electrostatic image holding surface is not distant from an electrostatic image, so the toner scatter at the circumference of the image part is reduced.

Title: Data transmitter and data receiver
Inventor: FUKUI KIYOSHI
IPC: H04L7/08
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce decline in transmission efficiency by the insertion of a marker for a flag while more ensuring the discrimination of an original flag and the flag in data by inserting the marker for indicating that a bit pattern is not the flag immediately after the bit pattern in the case of detecting the bit pattern highly correlated to the flag in digital data to be transmitted. SOLUTION: A PN1 correlation detector 103 detects the bit pattern highly correlated to a PN flag 'PN1' from inputted frame data and outputs detection signals. A marker insertion circuit 104 inserts the marker 'PN2' immediately after the detected bit pattern by the detection signals from the PN1 correlation detector 103. A flag insertion circuit 105 inserts the PN flag 'PN1' at the rise position of the pulse of frame synchronization signals to the output of the marker insertion circuit 104 and outputs it to a reception side. Thus, the probability of generating flag emulation is lowered.

Title: Band sawing machine
Inventor: FUKUSHIMA KAZUTAKA
IPC: B23D53/00
Filed: 1986-03-10
Abstract: PURPOSE:To eliminate restrictions on the cutting length of a workpiece, obviate necessity for returning a band saw and make overall construction simple by disposing in a laterals direction the sides of both straight advancing parts of an endless band saw so hung on a pair of pulleys as to be capable of circulation. CONSTITUTION:The side 7a of the straight advancing part 7 of a band saw 5 hung on a pair of pulleys 3 is arrayed with a guide roller 8 in a line toward a width direction and the passage 9 of the straight advancing part 7 is formed in the same line within an identical plane. When a workpiece 'W' is cut, therefore, the straight advancing part 7 at both use and non-use sides is arrayed in a line and as a trailing line passes through the groove of the workpiece 'W' cut with a leading line, the straight advancing part 7 at the non-use side does not come in contact with a part of the workpiece 'W' when said part 7 at the use side is employed for cutting. Consequently, cutting length becomes free from restrictions. Also, the band saw 5 is curved toward the direction of the thickness thereof, thereby restricting the return of the saw 5 for the formation of said part 7. Therefore, the fatigue of the band saw 5 is alleviated and overall construction can be made simple.

Title: Automatic zooming mechanism of interferometer and interference-fringe receiving method
Inventor: TADA TAKESHI
IPC: G06T1/00
Filed: 1991-03-18
Abstract: PURPOSE:To determine the magnification in zooming only by inputting the size of a material to be measured by approximating the relationship between the moving amount of the movable part of a zoom lens and the number of pixels of interference fringes projected on an image sensing element (CCD) camera to a function. CONSTITUTION:Luminous flux passes through an interference optical system 30 and an image focusing lens 1. The image of the interference fringes formed on a projecting plate 2 is expanded with a zoom lens system 3b and a condenser lens 4 and projected on a CCD 5. The image is monitored 6 and sent into a frame memory 9. The image data are transferred into a computer 10. In the computer 10, the function which is obtained by approximating the amount of movement of a movable part 3a in zooming to the number of pixels in the image of the interference fringes is stored. At this time, when an operator inputs the size of a material to be measured in the longitudinal direction, the size is converted into the number of the pixels with the computer 10. Furthermore, the computer 10 computes the number of required pulses by using the stored functions, outputs the command to a motor controller 8 and changes the zooming magnification.
