Abstract: PURPOSE:To reduce a flame temperature and to burn with high load by supplying lower mixture gas of unburned state than oxygen concentration in the atmosphere from a second flame port to flame to be formed on a first flame port. CONSTITUTION:A part of mixture gas in which primary air ratio in a first mixture gas chamber 14 is set from 30 to 60% is injected from a first flame port 7, residual mixture gas is introduced to a second mixture gas chamber 9 through a mixture gas passage 8, then mixed with the air from an air intake port 13, and injected as mixture gas having 170 - 250% of primary air ratio and having a combustible limit or lower from a second flame port 12. The secondary air is fed between a burner body 6 and other burner body from a lower part to an upper part, part of it is fed into the chamber 9, and the residue is supplied as secondary air of the port 12 along the outer periphery of a second mixture gas chamber wall plate 10, and operated as the secondary air of the port 7. Thus, a flame reaction zone temperature is lowered, it is not necessary to provide a second combustion chamber like two-stage combustions but performs combustion with high load.

Title: Medium carrying device
Inventor: HAMADA YASUYOSHI
IPC: B65H5/38
Filed: 1985-07-19
Abstract: PURPOSE:To prevent the trouble of medium carrying in an aperture part by providing a guide means which restrains the rise of a medium in the aperture part of a guide. CONSTITUTION:When a sheet 11 is set to a guide 3 and is inserted to a carrying path, it is taken into the carrying path by carrying rolls 1 and 1' and advances in the carrying path formed with guides 3 and 4. The front end of the sheet 1 is detected by a sensor 12. The time from passage of the front end of the sheet, which is fed at a certain speed, under the sensor 11 to arrival at a guide part 4a can be settled, and a driving motor 6 is driven after a certain time to open a moving guide 5, and the driving motor 6 is stopped by the output of a sensor 13, and image reading by an image sensor 10 is started. When the rear end of the sheet 11 is detected by the image sensor 10 according as the sheet 11 is fed, a processing circuit is made conductive to reverse the driving motor 6. The guide 5 is closed then, and the driving motor 6 is stopped when a sensor 14 detects that the guide 15 is closed. Since the guide 5 is opened only when the image of the sheet 11 is read, paper piecese and dust are prevented from entering the carrying path.

Title: Chroma noise reduction device
Inventor: FUJIWARA KOJI
IPC: H04N9/87
Filed: 1992-06-17
Abstract: PURPOSE:To reduce the number of pins and the number of externally mounted components by using plural adders, plural limiter amplifiers and one delay circuit so as to devise specific circuit configuration. CONSTITUTION:An adder 2 calculates a difference between a reproduced color signal vi being an input signal of the device and an output signal v0 of the device. A limiter amplifier 4 receives the calculated difference and outputs the signal v1 whose amplitude is limited. A difference v2 between the signal v1 and the input signal vi is calculated by an adder 6. The difference v2 is fed to a delay circuit comprising, e.g. a CCD and a signal v3 delayed by 1H is outputted. Furthermore, the input signal vi is inputted to a limiter amplifier 8, and a difference v4 between the output of the limiter amplifier 8 and the input signal vi is calculated by an adder 10. Then a difference between the signal v4 and the signal v3 is calculated by an adder 12 and the result of calculation is an output signal v0. Thus, one delay circuit 18 being an externally mounted circuit is enough and two connection terminals (pins) 17a, 17b are enough for the purpose.
