Title: Laser beam marking apparatus
Inventor: ISHIGURO KOJI
IPC: B23K26/00
Filed: 1990-11-30
Abstract: PURPOSE:To improve utilizing ratio of laser beam energy by equalizing a plane of polarization of the laser beam passing through clotted part on liquid crystal mask and a plane of polarization of the laser beam passing through gap part between the dotted parts and marking with a beam splitter. CONSTITUTION:As the beam splitter 7 is set so that the laser beam passing through the dotted part in the liquid crystal mask 4 for reflecting the marking contents can penetrate, the laser beam penetrating the gap part between the dotted parts on the marking surface can be worked so as to contain the marking contents. That is, the laser beam, too, penetrating the gap part between the dotted parts can be used as the marking contents with the beam splitter 7. By this method, the laser beam energy passing through the gap part between the dotted parts, can be effectively utilized and the large area marking can be executed. Further, the marking letter comes to plane letter from the dotted letter and the clear marking is executed.

Title: Current detection type apc circuit
Inventor: OOTA YUKIHITO
IPC: H04B1/40
Filed: 1991-12-24
Abstract: PURPOSE:To eliminate voltage drop at a current detector and to efficiently control output power by letting the final current of a PA flow to a coil and converting generated magnetic flux density to an electric signal by a Hall element. CONSTITUTION:When the output power at an output terminal 14 is fluctuated, the final step current is changed corresponding to the fluctuation. Corresponding to the output signal of magnetic flux density 17/Hall element 18, a voltage control circuit 19 controls the power supply voltage of a first-step amplifier circuit 12. When the output power at the output terminal 14 is amplified, the output signal of the Hall element 18 is increased corresponding to the output power. At such a time, the voltage control circuit 19 is operated so as to decrease the power supply voltage of the first-step amplifier circuit 12. Thus, the gain of the first-step amplifier circuit 12 is dropped and an operation is executed to keep the output power constant at the output terminal 14. Thus, since the output power at the output terminal 14 is equivalently detected and the gain of the first-step amplifier circuit 12 is changed based on this output power, a loop is formed as the APC circuit to keep the output power constant at the output terminal 14.

Title: Optimal and quasi-optimal vibration control method including low-pass filter
Inventor: SEDO KAZUTO
IPC: G05D19/02
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To enable vibration of a low-degree vibration mode generated at a structure to be effectively controlled by providing a low-pass filter calculation means for reducing sensitivity to a vibration mode with its degree higher than the maximum degree and controlling target vibration to be controlled from that calculation result and the displacement and speed signal of each mass point. SOLUTION: A vibration system of a 5-mass point system model 8 has the sixth to infinitive degree modes other than first to fifth degree vibration mode system targeted for control. Therefore, if a control system is designed by ignoring these modes, the ignored modes generates unstable spill-over. When the ignored vibration mode with the minimum degree is selected for an uncontrollable mode and the vibration mode with the next degree is selected for a non- observed vibration mode, the signals of these modes are shut down from a control loop and do not influence control. However, the higher-degree vibration mode influences control, therefore, unstable spill-over is prevented by shutting down this by means of a low-pass filter.

And then the vacuum pump for the nozzle 6 positioned at the pierced hole 3 is actuated. In this way, the string 4 can be easily threaded along the air stream even if the hole is curved. And hence, this can be used in an assembly- line system.

IPC: G06T1/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide an amount of skew detection device which can detect whether the motion is skew or meandering state and also can grasp an accurate moved variable by preparing the spherical bodies which revolve with feed of an original and detecting the revolution of the spherical body in the original feeding direction and the revolution of the spherical body in the direction rectangular to the original feeding direction. SOLUTION: The spherical bodies 1 and 8 are added to an original feed mechanism 2 and always touch an original 3 when it's fed. The moved variable of the original 3 is measured in its original feeding direction A by measuring the moved variable of a transmission mechanism 4 by a detection mechanism 5. Then the moved variable of the original 3 is measured in its skew shift direction B by measuring the moved variable of a transmission mechanism 6 by a detection mechanism 7. In the same way, the transmission mechanism 9 and 11 can measure the moved variable of the original 3. The moved variables measured by the detection mechanisms 7 and 12 are compared with each other. When both moved variables are equal with each other, it is a skew in which the original 3 is shifted in parallel that can be corrected by the image processing.  If both moved variables are not equal to each other, the original 3 has an irregular and meandering shift than cannot be corrected by the image processing.
