Abstract: PURPOSE:To improve the workability of centering by carrying out the centering of an object, which is carried in sideways, by means of a pair of right and left centering arms in the width direction and a single centering push-board in the length direction which are both driven by a single driving source. CONSTITUTION:The stopping position of an object 2, which is carried in astridingly on two rows of parallel, article carrying-in conveyors 1, 1, is determined by making the carried-in end of the object brough in contact with a pair of stop rollers 3, while a cylinder device 4 is operated simultaneously. Thereby, a rack rod 5a, a pinion 6, and a rack rod 5b are operated in sequence, making centering arms 7a, 7b in the width direction, which are provided in an integrated form with the rack rods 5a, 5b respectively, approach the sides of the object 2 simultaneously. The rotation of the pinion 6 makes a crank arm 9 rotate, causing a push-board 15 for centering in the length direction, to move toward the object 2 side through a connecting rod 11. Thus, the centering to the object 2 in both width and length directions can be carried out by the above stated means.

IPC: B41J11/42
Filed: 1985-11-01
Abstract: PURPOSE:To prevent the influence of reduction in a light amount and to improve the accuracy of the stopping position of a sheet by compressing the maximum and minimum voltage values determined by the light amount emitted from an optical system, and controlling a sheet feed motor in a range of the compressed voltage values. CONSTITUTION:A code plate 1, a light emitting diode 2 are provided, and a comparator 9 for comparing +3.5V produced by resistors 5, 6 with the output of a phototransistor 3, and a comparator 10 for comparing +1.5V produced by resistors 7, 8 with the output of the phototransistor 3 are provided. The comparators 9, 10 close a switch 14 when the output of the phototransistor 3 is in a range of +3.5V-1.5V and closes a switch 15 wnen it becomes +3.5V or higher, and closes a switch 16 when it becomes +1.5V or lower to apply it to a terminal D. Thus, even if the potential rises even if a light amount decreases, it is not affected even if it is up to +1.5V, and the balance of the driving force can be maintained even if the rotating direction of a motor is either. When the driving force of the motor is equalized in both when it is +1.5V or 0V and when it is +3.5V or +1.5V, the accuracy of the stopping position can be improved.

Title: Filter for inverter
Inventor: SASHIDA NOBUO
IPC: H02M1/12
Filed: 1986-10-15
Abstract: PURPOSE:To reduce the generation of common mode noise, by composing respective output poles in the filter of an inverter so that the impedances of the poles may be essentially equal to each other. CONSTITUTION:Reactors 3a, 3b and a capacitor 4 connected to a space between the reactors 3a, 3b constitute a filter. The filter is connected to the output poles of an inverter 2. Floating capacitive component 7a between the reactor 3a and an earth potential section 6, and floating capacitive component 7b between the reactor 3b and the earth potential section 6 have essentially the same floating capacity values. An impedance between the reactor 3a and the floating capacitive section 7a, and an impedance between the reactor 3b and the floating capacitive section 7b are essentially equal to each other, and so high frequency component contained in line voltage can be prevented from being converted to common mode noise due to the unbalance of impedance to ground.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To suppress a rise in the temperature of the coil of a voice coil motor as a driving mechanism part when an optical axis is corrected in an optical spatial transmission device. SOLUTION: A heat sink 18Ye formed by bending a thin plate of nonmagnetic metal with high heat conductivity is fitted by being pressed against three sides except one side of a coil 18Yb sandwiched between a couple of magnets 18Yd and clamped with a screw to a base plate holding the coil 18Yb.
