Title: Composition for depositing low melting solder and production of circuit board precoated with low melting solder
Inventor: FUSE KENICHI
IPC: H05K3/34
Filed: 1991-03-27
Abstract: PURPOSE:To selectively deposit low melting solder on pad parts so that a precoat can be formed by applying the compsn. for depositing specific low melting solder on circuit patterns and heating the compsn. at a low temp. CONSTITUTION:The essential components of the compsn. for depositing the low melting solder are composed of metallic tin powder, metallic bismuth powder and lead salt of org. acid. The salt of org. acid comes into contact with tin having a high ionization tendency to generate an ion exchange reaction and the tin partly ionizes to form the salt of org. acid when this compsn. is heated at a low temp. The lead constituting the original org. acid salt deposits simultaneously to generate the alloy with the tin of the powder metal and to form the solder. The precoat is thus formed. Electronic parts are mounted on this precoated circuit board and the solder is subjected to reflow, by which the low melting solder is melted and the lead wires of the electronic parts are joined.

Filed: 1988-04-12
Abstract: PURPOSE:To enable the moving of a grid between a photographing position and a retracting position and the rocking of the grid in the photographing position and to improve reliability by providing a simple grid mobile mechanism. CONSTITUTION:The revolution of one driving motor 4 provided on the photographing position is transmitted through a first gear 12 and a second gear 14 to a fliction clutch 16. When a grid frame 5 is held by a stopper 17 in the photographing position, slipping is generated by the fliction clutch 16 to the revolution of the driving motor 4 and the revolution of a driving pulley 1 is stopped. In a condition that a rocking lever 9a provided on a holding member 9 is brought into contact with a bearing 13 supported in the turning edge of an arm 12 to be pressed by a spring 10 by the equal speed revolution of the arm 12, a grid 7 is rocked with executing reciprocating motion in an interval with a range 2a determined by a turning center radius (a) of the arm 12 periodically. Thus, the grid 7 can be moved between the photographing position and retracting position and rocked in the photographing position. Then, the whole grid moving mechanism can be simple, compact and light. Then, the reliability to a spot shot device can be improved.

Title: Method for extracting and recognizing character pattern
Inventor: FUJIMORI HIDEKI
IPC: G06K9/46
Filed: 1994-04-27
Abstract: PURPOSE:To provide a uniform character pattern by calculating average density for each area, which is formed by bisecting the rectangular area of a character, binarizing the character for each area with a threshold value corresponding to that average density and defining a binary pattern as a combined character pattern. CONSTITUTION:The binary character pattern is extracted from a concentration image 93 provided by picking up a source image 97. In a conventional method, when the character is binarized with the average density of an entire character area, the left side complicating strokes is a little crashed but oppositely, the right side slightly scratches lines since the number of strokes is a little. When a character is bisected at the midpoint, however, the left side character area improves the average density, as a result, the threshold value of binarizing is increased and the character is binarized thinner in comparison with the conventional method. Oppositely, since the right side lowers in the average density, the threshold value is decreased and the character is binarized thicker. Therefore, the character pattern synthesizing images binarized separately on the right and left sides is more approximated to the source image than the conventional method.

IPC: H05K3/34
Filed: 1986-04-18
Abstract: PURPOSE:To make automatic operation easy and to improve reliability by enabling soldering a pattern by such a method as previous dip soldering, by soldering an IC by the reference of the height of a dip solder and by releasing the elasticity of a lead leg after the soldering. CONSTITUTION:Soldering is carried out by the reference of a dip solder 16. The reference of the height for soldering an IC 10 is made nearly equal to the height of the dip solder 16 and lead legs 13, 14 are so adjusted as to the quantity of absorbing the dispersion of the lead legs 13, 14 and the dispersion of the dimension in the direction of the height of the dip solder 16. Consequently, the soldering is made possible by making no change of the height of the IC 10 after the soldering and by forming wedge like solder fillets 21, 22 between the lead legs 13, 14 and a conductive pattern 15. After the soldering, no stress remains and reliability is further increased since elasticity can be released by the adjustment of the lead legs 13, 14.

Title: Image forming apparatus
Inventor: INUZUKA TSUNEKI
IPC: G03G15/00
Filed: 1979-07-16
Abstract: PURPOSE:To decide reasonably the optimal pretreatment time of a rotary body, by combining the rotation mode of the rotary body and its rotation stopping means to control its rotation time length. CONSTITUTION:Turning on a main switch lights lamp 3, opens shutter 25, actuates corona charger 6, rotates drum 2, and cleans drum face 2. When the inner heater of fixing roller 20 reaches a fixing enabling temperature, roller 20 generates a copying OK signal. Not turning on a copying switch allows drum 2 to continue its rotation since that time, and when pulses from an encoder for generating few pulses per rotation of drum 1 and provided in a drum driving system are counted up to a given number, drum 2 is stopped. Turning on the copying switch during rotation of drum 2 or its pause closes shutter 25 to rotate drum 2, moves platen 1 forward to run slit exposure after almost one rotation, thus permitting a high contrast static image to be formed on drum 2 and developed with toner.

Filed: 1988-04-15
Abstract: PURPOSE:To enable the detection of particulates by providing polarizing plates on an optical path of an irradiation beam and an optical path of a scattered light sensing system respectively so that the respective directions of polarization intersect each other perpendicularly. CONSTITUTION:A laser beam 4 is applied to a detection area 3 provided below a particulate generating element 2 in a vacuum vessel 1, and a scattered light 6 generated when particulates 5 pass is sensed by a light-sensing system 7 and converted into an electric signal. The particulates are counted by a signal processing. Herein polarizing plates 9 are provided on the optical paths of an irradiating system and the light- sensing system so that the respective directions of polarization intersect each other perpendicularly. Accordingly, stray light 10 caused by the reflection and diffraction of the irradiating light at a transparent window is intercepted by the polarizing plate 9 of the light-sensing system, since the stray light has only a horizontal component. Meanwhile, the vertical component of the scattered light 6 from the particulates, which has both horizontal and vertical components, is not intercepted by the polarizing plate 9 of the light-sensing system, but is made to enter a detector 7. In the detector 7, in this way, the stray light 10 is not detected and only the scattered light 6 from the particulates is detected. Thereby the detection of the particulates is enabled.

Filed: 1987-04-14
Abstract: PURPOSE:To facilitate copying operation and to prevent a device from increasing in size and cost by reading an image area of specific color by an image sensor and erasing an image except in the image area on the surface of a photosensitive body by a blank lamp. CONSTITUTION:An optical system 56 scans a preliminarily the image of a color original before a copying process and the image area of the specific color is read by an image sensor 2 during the preliminary scan. Then the image except in the image area on the surface of the photosensitive body 22 is erased by the blank lamp 1 during the copying process of the specific color. An image is therefore formed only on the read image area during the copying process of the specific color and no image is formed on other areas. Consequently, the operation is facilitated and the device is prevented from increasing in size and reduced in cost.
