Title: Fire extinguishing nozzle for powdery fire extinguishing apparatus
Inventor: TAKEMURA KINJI
IPC: A62C31/24
Filed: 1990-06-21
Abstract: PURPOSE:To certainly extinguish the fire in the whole area in a determined space by boring a plurality of first orifice holes at a right angle to the cylindrical surface close to the inlet port of a nozzle body, boring a plurality of second orifice holes at a right angle to the conical surface closer to the top, and radially protruding a plurality of dispersing bars in cross to the axial center extending lines of the second orifice holes on the top end of the nozzle body. CONSTITUTION:A powdery fire extinguishing agent jetted through first orifice holes 4, 4... is dusted within a relatively narrow angle range. As the powdery fire extinguishing agent is an extremely fine solid body, it takes a pattern as loosing the force at the time of jet as it is separated from a fire extinguishing nozzle and settling little by little, and takes a complete symmetric form in plane view. The powdery fire extinguishing agent jetted through second orifice holes 6, 6... are widely dispersed because of dispersing bars 7, 7... situated close thereto. The central line 8 of the second orifice hole 6 forms an angle theta to the dispersing bar 7, so that the degree of dispersion of the powdery fire extinguishing agent near the axial center of the fire extinguishing nozzle or the space center is enhanced, and inside missing phenomenon of the powdery fire extinguishing agent is eliminated. When this fire extinguishing nozzle is used, a fire extinguishing target space can completely be covered with the powdery fire extinguishing agent.

Abstract: PURPOSE:To make it possible to apply a large bore-size carburetor to a V-type engine with advantages obtained by V-type engines being maintained, by shifting the center axis of an intake-air passage in each of a plurality of cylinders in the direction away from a cylinder adjacent to the first-mentioned cylinder with respect to the cylinder axis. CONSTITUTION:A cylinder 12 is formed in a cyliner block 10, piercing the latter, longitudinally. Further, the cylinder 12 is formed in the upper section of its side wall with an exhaust passage 13, and in the lower section thereof with an intake air passage 14. In this arrangement, the intake-air passage 14 is so formed that the position on the center line B at a connection port 14a or the center position of the connection port 14a is shifted toward either side of the plane E which passes through the axis D of the cylinder 12 and is orthogonal to the crank shaft, for example, toward the upper side, by a predetermined distance X. Two of the thus formed cylinder blocks 10 are so arranged that the shifted directions of their intake-air passages 14 are directed toward the widthwise outside of the engine. With this arrangement, the distance between the connection ports 14a of the intake-passages 14 is enlarged to attain the predetermined object.

Abstract: PURPOSE:To make the surface of a substrate from which an SiO2 film is removed hydrophilic and facilitate avoiding adhesion of dust by employing solution of hydrofluoric acid mixed with alcohol as etchant. CONSTITUTION:When an SiO2 film formed on an Si substrate is etched by solution of hydrofluoric acid containing alcohol, water-repellent radicals in alcohol are adsorbed by the water-repellent surface of the substrate from which the SiO2 film is removed and, as a result, the substrate surface is covered with hydrophilic OH radicals constituting alcohol to make the substrate surface hydrophilic so that adhesion of dust can be avoided. Therefore, rate of pattern defects can be reduced and pin-holes in the SiO2 film can be avoided.

Inventor: ISHIDA TOKUJI
IPC: G02B7/34
Filed: 1983-09-06
Abstract: PURPOSE:To detect the invariably correct amount of defocusing and facilitate the assembly of an optical system for focus detection and the installation into a camera by making corrections on the basis of an image interval correcting signal even when the interval between the 1st and 2nd images is different from a designed value at the time of focusing on an image sensor. CONSTITUTION:A setting means 42 for the amount of image interval correction is so formed as to output the analog voltage signal corresponding to the amount of image interval correction which is the difference between the designed value and measured value of the interval between the 1st and the 2nd images on the image sensor 16 at the time of focusing by adjustment or change of a resistance R1. An analog multiplexer 44 leads the analog voltage signal from an amplifier 22 and the analog voltage signal from said setting means 42 selectively to an A/D converter 24 according to the A/D conversion input control signal IS from a microcomputer 18. Consequently, even when the image interval between the 1st and the 2nd images during focusing is different from the designed value, the amount of defocusing is calculated accurately and an accurate focus adjustment is made on the basis of it.

Abstract: PURPOSE:To increase the substantial storage capacity of a computer system without increasing the capacity of a main storage device, by executing a data transfer between an extended storage device and an external storage device through a specific area of the main storage device, so that a dead capacity of the extended storage device always exceeds a prescribed quantity. CONSTITUTION:When a frame 6a of an extended storage device 6 has been allocated in order to transfer the contents of a frame 2a of a main storage device 2, in case a dead frame quantity of the extended storage device 6 is below a prescribed quantity, plural frames are selected under a prescribed algorithm from in the frame of the extended storage device 6. Subsequently, its contents are transferred to a specific area 2b of the main storage device, which has been secured in advance, and thereafter, the contents of this area are written and saved in an external storage device 5. As a result, the frame of the extended storage device 6, whose contents have been saved can be utilized again as a dead frame. In this way, the substantial storage capacity of this kind of computer system is increased without increasing the storage capacity of the main storage device 2.

Abstract: PURPOSE:To execute various types of display by executing a logical operation, etc., for the pieces of picture information outputted from plural window modules based on a control signal from an external part and outputting a video signal to a display device. CONSTITUTION:A raster operation circuit 21 apparently simultaneously takes in the data of difference windows from memories 15, 16, and 17 of respective window modules 100, 200 and 300 through data output parts 18, 19, and 20, executes the logical operation, etc., for the data, generates the video signal, and outputs the video signal to a CRT 10. Consequently, at a point where the first window shifts to the second window, the data of the window module 300 can be fetched by the logical operation. Further, for example, since the data to indicate a background picture from the window module 100 and the data of the first window from the window module 200 are simultaneously taken in the raster operation circuit 21, the background picture can be displayed as a perspective picture behind the first window by mixing the above-mentioned simultaneously data.

Title: Freeze-thaw treating device for sludge
Inventor: TOSHIFUJI NAOTAKE
IPC: C02F11/20
Filed: 1981-10-15
Abstract: PURPOSE:To discharge flocs of sludge formed into large sizes by freeze-thaw treatments to the outside of a freeze-thaw device of a sludge without breaking the flocs by providing a water discharge pipe, a sludge discharge pipe provided with a valve extending from a cover for the sludge up to near the bottom of a storage tank, and an overflow pipe extending from the inside of the sludge cover to the sludge cover provided on the sludge discharge side of a thawing chamber for sludge. CONSTITUTION:In the starting stage of the device, a valve 10 is closed to feed water 11 in a sludge cover 7, and while the air of the cover 7 is discharged from an overflow pipe 12, the inside of the cover 7 is filled with the water, then the supply 7 of water is stopped. Thereafter the valve 10 is opened. Even if the valve 10 is opened, the bottom ends of a sludge discharge pipe 9 and the pipe 12 are in the sludge in a storage tank 8 and therefore no air enters the cover 7. In this state the operation for discharging of the sludge is carried out. Since the cover 7 and the pipe 9 are respectively filled with the water, the freeze-thawn sludge is discharged slowly and stored in the tank 8 without falling down quickly. Thus desired dehydrating performance is maintained without breaking the flocs.
