Filed: 1990-09-21
Abstract: PURPOSE:To image an extremely small component axially of a nozzle and to effectively mount it on a printed board by providing four cutouts on the side of a cylindrical part in contact with an electronic component of an electronic component suction nozzle. CONSTITUTION:Four rectangular cutouts 9A, 9B, 9C, 9D symmetrical to an axial center are formed at the edge of a nozzle 8, suction ports are formed in a shape similar to an ellipse by coupling the two opposed semicircles by two parallel straight lines. Both ends of two opposed long sides of a rectangular electronic component 2, totally four ends are all present in an entire contour image of the component 2 and the nozzle 8. The component 2 is sucked at displacement (DELTAX, DELTAY, DELTAtheta) to the axial center of the nozzle 8. The binarized entire image is approximated by a polygonal shape, and the coordinate values X, Y of the vertex 14 are calculated. Thus, only the image of the component 2 is extracted, the position (graphical center) of the center of gravity of the polygonal shape and the direction of the inertial main axis are calculated to calculate the displacement DELTAX, DELTAY, and DELTAtheta.

Filed: 1983-12-27
Abstract: PURPOSE:To simplify the mechanism by using a cam plate driven with a single solenoid so as to hold a magnetic head to the state of recording/reproduction/ fast feed reproduction with a prescribed control signal so as to allow the single solenoid to hold each state. CONSTITUTION:A solenoid 29 is connected to a head chassis 7 and the cam plate 25 is fitted freely turnably to a pin 23. When recording/reproduction is commanded from the stop position, the cam plate 25 is lifted upward by a high level output of an output part 35c, a head 9 is contacted strongly onto a tape so as to attain recording/reproduction. When the fast feed reproduction is commanded in this state, a notch 25b of the cam plate 25 and the pin 24 are engaged with the low level output of the output part 35c, the head 9 contacts with the tape weakly. After the level is brought once into a high level from the output section 35c with the next pulse application, a low level is outputted, the engagement between the pin 24 and the notch 25b is released and the tape recorder restores to the stop mode. Thus, each mode is controlled by a single solenoid so as to simplify the constitution.

Abstract: PURPOSE:To pour the exact amt. at an adequate pouring speed by comparing the pouring speed obtainable from a weighing signal for a ladle with a set value, controlling the pouring speed, changing the pouring speed with the set value of the pouring time and stopping the pouring upon completion of the supply of the prescribed pouring amt. CONSTITUTION:The weighing signal of a weighing device 7 for the weight of he molten metal including the weight of the ladle 1, etc. is first stored by a control part 10 prior to pouring. The ladle 1 is then rotated at a specified speed by a driving decelerator 3 and when the molten metal begins to flow out of a tapping port 2, the outflow is detected by a detector 8 and the detection signal is fed to the part 10. Then the part 10 outputs the rotating speed signal to a control part 11 of the device 3 at the pouring speed set and stored by an operating part 9. The control part 10 calculates at the same time the pouring amt. per unit time (pouring speed) by the signal from the meter 7, compares the same with the set pouring speed and corrects the rotating speed signal. The control of the pouring speed is repeated until the signal from the meter 7 attains the set value of the pouring rate. The device 3 is stopped and is run backward to stop the pouring when the set value of the pouring amt. is attained.

SOLUTION: When performing water passing operation to obtain filtrate, raw water is caused to flow upward in a column filter 10 by a water supply pump P1 and a filter medium 13 is pressed against the back surface of an upper strainer 11 by the water passing pressure. After the contained turbid matter is caught by the filter medium 13 when the raw water is passed through the filter medium 13 thus compacted, filtrate is caused to flow out from a water collecting pipe 15. Next, on backwashing, a circulating pump P2 is operated, water is circulated in the column filter 10 as a downflow and in the circulating pipe 18 as an upflow. At this time, the filter medium 12 contacts with an impeller or the like rotating of the circulating pump P2 to squeeze the caught turbid matter out of the filter medium. Then, the turbid matter removed from the filter medium 13 is made to sink into a water phase below the filter medium 13 and is discharged from a drain pipe 16 together with water.

IPC: F23K5/00
Filed: 1987-10-05
Abstract: PURPOSE:To introduce a purge gas to a burning flame by use of other fuel to forcibly burn the purge gas by providing the burner with a purge gas introducing passage for introducing the purge gas into a flame of the burner. CONSTITUTION:A purge gas introducing passage 3 is formed into a bottomed cylinder which intersects a combustion chamber 1 slantly from the base direction. A connecting pipe 12 to a conduit pipe 4 is connected to the bottom part of the passage 3. The combustion apparatus (A) is connected to the conduit pipe 4 through the connecting pipe 12 and also connected to a propane gas bomb 16. A combustion gas is sent into a burner 2 and simultaneously a spark rod 9 is actuated to ignite the combustion gas, and a purge gas is introduced into a purge gas burning burner 13 which monitoring the combustion state by a flame detection rod 10. As a result, the inner part of the combustion chamber 1 is filled with the flame of the burner 2, and hence a gas ejected from the burner 13 for combustion of purge gas certainly passes through the flame and ignited by the flame of the burner 2. When the concentration of the gas is high, the gas is burnt by the burner 13 for combustion of the purge gas. When the concentration of the gas is low, the gas burns by the flame of the burner 2. Accordingly, the gas is completely burnt and the diffusion of the unburnt gas can be prevented.
