Title: Combustion of low nox in combustion chamber
Inventor: OOHARA SEIJI
IPC: F23C99/00
Filed: 1980-10-27
Abstract: PURPOSE: To lower NO x  in a combustion chamber by a method wherein as fuel and burning air are blown from the same hole, the flame of a burner is elongated and the NO x  produced by a burner on the upper stream is reduced through this elonagted flame.  
     CONSTITUTION: Oil is sprayed from an injector 2 at the point of an oil gun 1 and part of the burning air is supplied by a rotary blade 4 at the point of the injector from the ambient blowing passage 3 to the sprayed oil. The sprayed oil is burnt and forms a primary flame F as a piloting flame. Burning gas is supplied from a blowing passage 5 and most of the burning air cannot be mixed with the sprayed oil or the primary flame F near the burner but mixed at a place far fromthe burner and therefore the secondary flame F' produced there is elongated. As NO x  produced by the burner on the upper stream side passes through this long flame, the NO x  is reduced to N 2  by reducing agent like HC, HCN, NH 3 , etc. and low NO x  combustion is conducted in the combustion chamber.

Filed: 1983-08-17
Abstract: PURPOSE:To omit each process for aftertreatment of an electroformed copper plate and manufacturing of an electroformed iron plate and a matrix roll as well as to aim at shortening these stages of work and automating them, by manufacturing these elements through numerically controlled electro-discharge machining and embossed scroll manufacturing processes after molding and these electroformed copper plate manufacturing processes. CONSTITUTION:An electroformed copper plate 9 is manufactured through both molding and electroformed copper plate manufacturing processes and dipped in a machining tank 18 filled up with a derivative solution 17, then the electroformed copper plate 9 and a work body 19 are set to a N/C electro-discharge machining device. Next, on the basis of a machining position being stored in a memory, the work body 19 is shifted along the electroformed copper plate 9 as being rotated in an arrow direction, and discharge takes place with a discharge waveform by quantum-mechanical control commensurate to an uneven pattern on the electroformed copper plate whereby the uneven pattern on the electroformed copper plate 9 is stamped, thus a matrix roll is produced. Using this roll, the work 19 is processed through an embossed scroll manufacturing process whereby the required embossed scroll is securable. Thus, the data required for embossed scroll manufacturing can be shortened and it is automatically operated so that no skillfulness is required and, what is more, low-unit cost of production comes to fruition.

Title: High-frequency heating device
Inventor: YAMAZAKI TAKAHIKO
IPC: F24C15/16
Filed: 1985-07-09
Abstract: PURPOSE:To enable an unstable container to be mounted on a net in a stable condition and restrict a bad influence during heating operation as less as possible by a method wherein a more close pitch of the grid near a central part of the cooking grid is made. CONSTITUTION:A group of grids 2 positioned in a plane of an outer frame 1 of a cooking net is directed in a lateral or vertical direction and a relative pitch (b) of grids near the central part of the grids is made closer than a grid pitch (a) at both ends thereof. With this arrangement, even in case that containers having small bottom surface, a high center of gravity and unstable condition such as a rice bowl, glass cup, etc. are placed on the grid, they can be mounted on the close pitch part near central part and further can be set without being loosed or under a stable condition. Small containers are placed on a center line of the grid, so that the central part may define the position of the container and this close pitch of the grid is profitable in case of determing the distribution of the high frequency. Since the close pitch part (c) of the grid is positioned just above the lower heater 3, it is possible to prevent the central part of a bread toast etc. from being strongly baked under an influence of the lower heater 3.

Title: Image forming method
Inventor: HANADA SHINJI
IPC: G03G13/22
Filed: 1988-06-21
Abstract: PURPOSE:To reduce the cost of a device by using a photosensitive drum having sensitivity only to a single polarity and one kind of toner and optionally performing an image forming process including reverse development once or twice. CONSTITUTION:At the time of forming a negative image, the photosensitive body 1 is electrostatically charged in a specified polarity by a primary electrostatic charger 2, then image exposure is performed to form the latent images of a dark part and a light part on the photosensitive body 1 and the reverse development is performed to the light part with the developer of the same polarity as the electrostatic charging polarity of the photosensitive body 1. Meanwhile, at the time of forming a positive image, the negative image is temporarily formed on the photosensitive body 1, which is electrostatically charged in the polarity opposite to that in primary electrostatic charging, and a toner image on the photosensitive body 1 is eliminated by a cleaning means 5. After electrostatically recharging the cleaned photosensitive body 1 in the same polarity as that in primary electrostatic charging, the reverse development is performed with the developer of the same polarity as that in primary electrostatic charging to form the desired positive image. Since the reverse development is thus repeated twice in order to obtain the positive image, the cost of the device can be reduced.

Title: Method to read pick cell array
Inventor: KONDO RYUJI
IPC: H04N5/341
Filed: 1985-07-11
Abstract: PURPOSE:To eliminate a delay of exposure after the shutter is pushed down and to make a mechanical shutter unnecessary by impressing two continuous starting pulses tightly close hourly, to respective vertical lines of the array and including a step to store information read in response to the second starting pulse only. CONSTITUTION:A digital value 2J is outputted from a START signal by an A/D converter 44. In this condition, when 23 is changed over to on and the value of an output of a counter 43 reached J, a clock pulse phi1 is impressed to a vertical shift register (SR)21. When the output value reaches the value of 2j, FET23is changed over to off and FET24 is changed over to on, and the clock pulse is impressed to SR22. When the pulsereaches the 2J-th step of SR22, the counter 43 is reset and the pulse from the J+1 step of SR21 is shifted to the J+2J step. A Q output of FF39 is ''1,'' at the first half part of respective shift sequence of both SR, a pulse phi<2> is impressed to an address counter 34, and when the pulse reaches J at the last half part, the pulse phi<2> is not impressed to the counter 34. Consequently, only when the second reading of respective vertical lines of an array 12 is executed, the counter 23 supplies a forward address to a frame memory 36.

Filed: 1988-06-21
Abstract: PURPOSE:To control oscillation frequency difference between the two polarized light of laser beams accurately and stably by composing a semiconductor laser of an external resonator and inserting a quarter wave plate and a magneto-optic effect element arranged into a coil into the resonator. CONSTITUTION:Beams emitted from one of a semiconductor laser, on both end faces of which non-reflective coating is executed, are changed into parallel beams by a collimator lens, the plane of polarization is turned at 90 deg. by a quarter wave plate 14 and a reflecting mirror 12, and the beams are projected to the semiconductor laser again. The plane of polarization of beams emitted from the other of the semiconductor laser 11 is rotated only by a fixed angle by a magneto-optic effect element 16 and a reflecting mirror 13, and the beams are projected to the semiconductor laser 11 again, and oscillated. Since there are two natural polarized light of a resonator and there is difference between both proper values at that time, the natural polarized light has planes of polarization orthogonal by adjustment, and two beams having slightly different frequency can be oscillated simultaneously. The difference of the frequency can be regulated by controlling magnetic field intensity applied to the magneto-optic effect element 16.
