Title: Jet type soldering device
Inventor: SUZUKI MASATAKA
IPC: B23K1/08
Filed: 1994-01-25
Abstract: PURPOSE:To provide a jet type soldering device which is capable of preventing bridging, icicle or dripping and is simplified in constitution. CONSTITUTION:A secondary nozzle 125 is provided with 45 deg. inclination within a horizontal plane in a direction orthogonal with the moving direction of a substrate. The sequence of attaching and detaching of cutting of molten solder is controllable and the molten solder is surely cut by the terminals in the last part of the moving direction regardless of the arranging direction of the terminals of the substrate. Since a conveyor 30 for soldering transports the substrate in a horizontal direction, the height distance from the substrate with the molten solder plane is eliminated. The rear surface of the substrate and the molten solder are made flush with each other and there is no more dropping of the molten solder and, therefore, large vibrations are not generated around the dropped solder and the points where the molten solder and the terminals come into contact are capable of maintaining regularity, thereby preventing the bridging, icicle or dripping. Since the conveyor 30 for soldering to transport the substrate is horizontal, the need for a transfer device for height adjustment, etc., is eliminated and the constitution is simplified.

Title: Rider moving simulator
Inventor: OSHIRO MASAYUKI
IPC: G09B9/00
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To obtain large up and down strokes with the capability in which up and down.left and right.and front rear three directional movements are provided but, without changing the front and the rear and the left and the right positions by providing the up and down driving mechanism, which supports the rider's table with two arms that are crossed to each other in X-shape and linking the movement in the up and the down directions. SOLUTION: When an actuator 15 is operated in the shrinking direction, an arm 11 is rotated in the rising direction centered around the coupling section of an intermediate table 7 and the intermediate section of an arm 12 goes up because the intermediate section of the arm 12 is also coupled with the arm 11 at a pin 13 part. One end of the arm 12 coupled with a slider 9 is only movable in the front and the rear direction and is not movable in the going up direction. Thus, the end, which is coupled with a supporting member 14 of the arm 12, goes up. Therefore, a rider's table 1 also goes up. However, the positioning in the front and the rear direction with respect to the table 7 of the table 1 is determined by the coupling with the arm 12 and the table 1 does not move in the front and the rear direction even though the table 1 goes up.

Title: Low nox burner using pulverized coal
Inventor: ARASHI NORIO
IPC: F23D1/02
Filed: 1982-01-22
Abstract: PURPOSE:To supress generation of NOx in combustion to a low level by dividing the  pulverized coal according to the size of its particles and burning it separately. CONSTITUTION:Pulverized coal enters a nozzle 1 as fluid mixture 4 mixed with primary air which serves also as the transferrer of the coal. The fluid mixture 4 flowing  through the nozzle 1 toward a furnace 13 is imparted with a strong swirl while passing  through a swirler 7. By this swirling, the coal particles of relatively large diameter are  made to flow in the vicinity of the inner wall of the nozzle 1 under the centrifugal  force, whereas the coal particles of relatively small diameter are made to flow in the  central part, the latter is blown directly into the furnace 13 and burned. On the other hand, the large diameter coal particles flowing near the inner wall of the nozzle 1 is  made to dash out of an opening 8 of the nozzle 1 under the centrifugal force into a  secondary air nozzle 2, where it is mixed with secondary air and then blown into the  furnace 13. Accordingly, referring to a drawing, the large diameter coal particles are  distributed to a part I and the small diameter coal particles gather at a part II. In  the part II, a great amount of volatile component produced can be burned at a low air- fuel ratio. In the partI, though the air-fuel ratio is high, the coal can be burned with  a small amount of volatile component. Thus the generation of NOx can be supressed  to a great extent.

Filed: 1983-01-20
Abstract: PURPOSE:To switch the frequency with the center value of voltage of an AC signal and at the same time to simplify the constitution of an FSK modulation circuit, by switching the analog signal with the center value of voltage in response to the L and H values of a binary data signal. CONSTITUTION:An FF1 delivers the data signal synchronously with the clock signal. For a counter 2, one of plural preset terminals is connected to the output of the FF1 to decide a ratio with which the clock signal is divided into two types of frequencies in response to the output contents of the FF1. A counter 3 supplies a frequency f1 or f2 in response to the above-mentioned dividing ratio and then dividing and delivering the frequency. A switch circuit 6 produces a staircase wave of an optional number of steps from the output of the counter 3. A synchronism detecting circuit 4 detects the numerical value obtained when the output of the counter 3 passes the steps of half optional number of steps of the staircase wave and then applies the detection signal to the clock terminal of the FF1. Then the frequencies f1 and f2 which are decided in response to the L and H values of the input data signal are switched with the center value of voltage and delivered alternately from an A/D converting circuit 7.

Filed: 1983-01-20
Abstract: PURPOSE:To decrease tracking error by turning a head in response to the displacement of a sliding angle of a sliding member and decreasing the angular displacement of the head to a track in a sliding type optical recording and reproducing device. CONSTITUTION:Since a pulley 26 is not moved to a shaking arm 22, when the arm 22 is shaken, the relative angular position of the arm 22 to the pulley 26 is changed, the winding position of a belt 29 to the pulley 26 is changed, resulting that the winding position of the belt 29 to other pulley 27 is changed and the pulley 27 is turned by an angle in matching with the shaking angle of the arm 22. Thus, a head 28 is moved in parallel while keeping a prescribed attitude during the movement, an angular change delta of a disc 25 to an information track is much smaller than the angular change theta in a conventional example and the tracking error is very small.
