Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To improve the compression ratio of an image by measuring an exposure level in a peripheral part and that in a center part, comparing the output levels of both circuits for measurement, selecting a front light time correcting circuit when the image of the peripheral part is darker than that of the center part or selecting a rear light time correcting circuit when the former is brighter than the latter. SOLUTION: When it is judged that the exposure level measuring signal S122 of the peripheral part is higher than the exposure level measuring signal of the center part, that is, the state is of rear light, the comparison judging signal S126 of a comparing circuit 124 becomes '1' level, the comparison judging signal S124 of the rear light time correcting circuit 125 is selected by a selection switch circuit 127 and outputted to the correction video signal S12 of a preprocessing circuit.  Otherwise, when it is judged that the exposure level measuring signal S122 of the peripheral part is lower than that of the center part, that is, the state is of front light, the comparison judging signal S126 becomes '0' level, the correction video signal S125 of the front light time correcting circuit 126 is selected by the circuit 127 and outputted to the correction video signal S12 of the preprocessing circuit.

When the tray is raised, an excessive number of solder balls 3 are dropped into a hopper section by horizontally moving a squeegee 11 from one end to the other end of the tray. Then a low- pressure nitrogen gas is supplied to the tray from a gas supplying device through a vent hole 9 and filter 10. The supplied gas is blown upward from through holes 8 and slightly move the solder balls 3 upward. While the balls 3 are floated, a vacuum head 2 is brought nearer to the balls 3 from the top side to attract the balls 3 to the attracting holes 12 of the head 2. After the balls 3 are attracted to the holes 12, the head 2 is moved to a position above a substrate and the balls 3 are mounted on prescribed positions of the substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent the influence on an artificial satellite by the vibration of a mechanism in rotation of a flywheel by changing at least one of the driving torque and rotation angular velocity of the flywheel on the basis of the detected attitude angular velocity of the artificial satellite. SOLUTION: When an artificial satellite having a flywheel 11 loaded thereon is vibrated by any external force, the change of attitude angular of the artificial satellite is detected by an angular rate assembly 12. The difference signal between an external angular velocity command and the signal of the angular rate assembly 12 is amplified and imparted to the flywheel 11. The reaction torque generated by the flywheel 11 is taken as the drive torque of the artificial satellite to control the attitude fluctuation caused in the artificial satellite. According to such a structure, the damping function to the vibration of the artificial satellite can be also provided while controlling the rotation angular velocity for controlling the attitude of the artificial satellite to a desired one.

Abstract: PURPOSE: To obtain an electromagnetic motor which can be manufactured with a simplified structure, namely in a large quantity under the lower manufacturing cost by enabling independent manufacture of stator and coil, without requiring special accuracy in the mounting of the coil to the stator. CONSTITUTION: Branching sections 4, 6, 8 having branching angles of about 120 degrees are arranged on the stator piece or forehead 10 of a stator 2. First ends 4a, 6a, 8a of the three branching sections 4, 6 and 8 form magnetic pole expansions EP4, EP6 and EP8 which are placed face to face to rotate a rotor 1. A magneto-mechanical coupling is formed between the magnetic pole expansions EP4, EP6, EP8 and three coils 22, 24, 26. Since the three coils are mechanically independent, a coil extremely facilitates the assembling of a coil 28 on the core. Moreover, the stator piece 10 can be formed at a very high speed by a production method such as die molding or punching method.

Title: Method for monitoring drawing of horizontal and continuous casting ingot
Inventor: TAKEDA SHIYUUHEI
IPC: B22D11/16
Filed: 1982-05-31
Abstract: PURPOSE:To detect the breakdown of a solidified shell in a mold with good accuracy based on the measured value obtd. by measuring the strain or load in a means of fixing a refractory material interposed between a tundish and the mold at all times during casting. CONSTITUTION:A strain gage 12 is adhered to a bolt 5 in the intermediate position between a clamping plate 8 and a water-cooling jacket 9 to measure the tensile strain to be exerted on the bolt 5 at all times. If an ingot is drawn normally after casting of molten steel is started, the strain of the bolt 5 oscillates in a certain steady range in conformity with the cycle of drawing compression. However, when the 1st shell 5 in contact with a cylindrical refractory material 4 breaks, the strain of the bolt 5 changes sharply. As a result, whether the ingot is intermittently drawn stably at all times during casting or not is detected from the change in the strain of the bolt 5 with the simple equipment and with high accuracy in the stage of drawing the ingot intermittently in a horizontal state.
