Title: Annealing method for grain oriented structure material
Inventor: NAKANO KOSAKU
IPC: C21D1/26
Filed: 1985-04-12
Abstract: PURPOSE:To array recrystal grains in one direction and to prevent the deterioration in the characteristic of a grain oriented structure material by passing the grain oriented structure material through a heating zone which is provided with a temp. gradient and is heated up to the recrystallization temp. or above. CONSTITUTION:Heating devices 2 in which nichrome wires 3 are used are successively provided around a quartz pipe 1 to form a cylindrical annealing furnace in which the temp. gradient rising from the inlet side toward the outlet side is generated by changing the outputs of respective power sources. The grain oriented structure material such as copper wire formed by drawing a single crystal bar-shaped casting ingot is continuously passed in the axial central part of such pipe 1. The max. temp. of the temp. gradient is determined at the recrystallization temp. of the material or abve so that the recrystal grains are arrayed and grown in one direction. The grain oriented recrystallized structure material is thus easily obtd. by using the material worked from the unidirectionally solidified material according to the above-mentioned method.

Title: Automatic reading device for license plate number of automobile
Inventor: KATO KENJI
IPC: G06T1/00
Filed: 1990-03-26
Abstract: PURPOSE:To detect the approach detection of an automoble with sufficient accuracy without lighting a road and to read the license number of automobile number by deciding surround brightness at three stages at least, adjusting the exposure sensitivity of a camera corresponding to it and fetching an original image constantly. CONSTITUTION:All illuminance sensor 5 decides surrounding brightness at three stages. When it is bright or dark, shutter speed is made about 1/1000 second by an electronic shutter driving circuit 19. When it is medium brightness (dusk and so on), the shutter speed is made about 1/60 second. Then, an image signal is fetched and the approach of automobile is detected based on a profile. When it is bright, the license plate number of automoble reading processing is executed with appropreating the fetched image signal as it is. When it is the medium brightness or dark brightness, the shutter speed of a device 3 is made 1/1000 second, a stroboscope light emitting device 2 is driven through a stroboscope light-emitting circuit 18 and an original image is fetched again. The detecting processing of an automobile head is executed based on an original image and the license number of automobile detecting processing is advanced. The processing is same as the content of the approach processing of the automobile, however, since a stropboscope is light-emitted and the shutter speed is fast, the clear image can be obtained.

As a result, a position on a character panel face 1 indicated by the pen 2 is detected, and this position information is transferred to a converting circuit 6. Subsequently, the position information is converted to a character code string by a conversion table. When the position information indicates the second area (a11-anm) of a blank, its position information is converted to all the character code strings. When said information indicates the first area (b11-bnm), it is converted to a character code string after a special code.

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission cleaning catalyst device and exhaust emission cleaning method for an internal combustion engine which has a wide range of cleaning temperature and shows a NOx cleaning rate higher than a certain rate over the substantially whole range. SOLUTION: A high temperature type catalyst 2 which has a high cleaning temperature range for nitrogen oxide cleaning and a low temperature type catalyst 3 which has a lower cleaning temperature range compared to the high temperature type catalyst 2 are serially arranged from the upstream side of an exhaust path. The distance L from the high temperature type catalyst 2 to the low temperature type catalyst 3 is set so that the upper limit temperature of the cleaning temperature range of the low temperature type catalyst 3 to the inlet gas temperature of the high temperature type catalyst 2 is higher than the temperature where a hydrocarbon cleaning rate of the high temperature type catalyst 2 shows 10% and lower than the temperature of where the rate is 80% or less.  In the high temperature type catalyst 2, the portion of hydrocarbon of 10 or less carbon number in the exhaust gas in this temperature area increases, and since the low temperature type catalyst 3 shows satisfactory NOx cleaning performance in the presence of hydrocarbon of 10C or less, if the distance L between the catalysts is properly set, a gap between the cleaning ranges of both catalysts is eliminated and NOx cleaning rate is largely improved.

IPC: G11B5/33
Filed: 1995-04-05
Abstract: PURPOSE: To easily detect the magnetic flux of a minute area by detecting the change of a high frequency magnetic flux by a high frequency magnetic flux part. CONSTITUTION: High frequency magnetic fluxes are generated in a second magnetic path 5 and a bypath magnetic path 13 by allowing a high frequency current to flow through a coil 11 and by impressing a high frequency magnetic field to the second magnetic path 5 by a high frequency magnetic field impressing part 12. The detection magnetic flux caused by a magnetic recording medium impressed on a first magnetic path 2 from an electrode 3 changes the high frequency magnetic flux of a magnetic field modulation part 6 and changes the high frequency magnetic field in the modulation part 6.  The detection magnetic flux of the minute area is easily detected by detecting the change of the high frequency magnetic flux by a magnetic flux detecting part 9 thereby making the influece of noise caused by an external magnetic field small while making the shape of the magnetic field modulation part minute.

Title: Device for automatically positioning columnar parts
Inventor: MATSUEDA AKIRA
IPC: H05K13/04
Filed: 1979-06-22
Abstract: PURPOSE: To surely position a small columnar element in the element positioning section of a housing under air suction when the element is automatically fed by an automatic fitting machine or the like, by horizontally feeding the element from a chute to the element positioning section.  
     CONSTITUTION: When air is sucked through a connection hole 8 by a vacuum pump, a sucking force is caused through an air suction hole 6. As a result, an element 1 in the front end of a chute 4 is sucked and fed into the element positioning section 3 of a housing 2 through an element feed hole 5 by the sucking force applied from the air suction hole 6 so that the element is sucked on an end face 3b opposite the chute 4. The element 1 is thus surely located in a prescribed position. When the air suction is stopped, the sucking forces from the air suction holes 6, 7 fall instantaneously. As a result, the element 1 drops from the element positioning section 3 to a prescribed fall position.

Title: Electrophotographic copying device
Inventor: YAMADA TAKANOBU
IPC: G03G15/08
Filed: 1983-05-06
Abstract: PURPOSE:To simplify a constitution of a copying device itself by providing a destaticizing light source on the inside of a developer scattering preventive cylindrical body constitued of a transparent member, and also constituting so that a charge on the surface of an electrostatic latent image carrier body is erased when the destaticizing light source is turned on. CONSTITUTION:The surface of a photosensitive drum 2 reduces the potential of a latent image part of a toner which receives a light irradiation by a destaticizing lamp 31, namely, a negative charge, and a light for irradiating the background part reduces uniformly the background part. That is to say, the potential of both parts is lowered, maintaining a state that the potential of the latent image part is a little higher than the potential of the background part. On the other hand, even when the toner To adheres to the background part, the potential of the background part is lowered by a light irradiation of a destaticizing lamp 31, therefore, an electrostatic adsorbing force to the background part of the toner To is weakened extremely, and the toner To is separated and scattered from the surface of the photosensitive drum 2 by a rotation of the photosensitive drum 2, but on the surface of a hollow roller 31 of a developer scattering cylindrical body 10, a charge of the polarity opposite to a charge of the toner To is induced, therefore, the toner To is collected by the developer scattering cylindrical body 10.
