Title: Method and device for correcting position of object to be corrected
Inventor: AOKI TAKAYUKI
IPC: B23K26/02
Filed: 1988-08-04
Abstract: PURPOSE:To correct the position of an object to be corrected by detecting the centroid position of the region of only the marker, comparing the same with a previously taught normal centroid position and outputting the difference therebetween as a correction rate to a positioning controller. CONSTITUTION:The object W which is to be corrected and is gripped by a clamp 3 provided to a positioning device 2 is positioned by the control command from the positioning controller 7 and thereafter, a correction command signal is outputted to the I/O of an image processor 11 from the controller 7. The image processor 11 receives this correction command signal and takes in the image of the marker 5 by an image pickup device 9 installed above the marker 5 provided to the object W. This image is sent to the image processor 11 as the image data and is subjected to A/D conversion in an A/D converting part 13, following which the image is stored into a frame memory 15. The centroid position of the marker 5 is then detected by arithmetic processing by a CPU 17. The normal centroid position previously stored in a RAM 21 and the detected centroid position are compared by the CPU 17 and the deviation quantity thereof is outputted as the position correction data which is the correction rate via an I/O 23 to the positioning controller 7.

Title: Fluid distributor, method of supplying fluid and crossflow cooling tower
Inventor: BURADEIIMIRU KAPURAN
IPC: F28C1/04
Filed: 1992-07-21
Abstract: PURPOSE: To distribute water uniformly onto a heat carrying surface by receiving fluid at a distribution pan, a fluid carrying passage and an inlet chamber and supplying the fluid uniformly to the distribution pan thereby supplying a uniform static pressure head to each nozzle. CONSTITUTION: When fluid is fed to an inlet chamber 12, it is deflected to the horizontal direction. The majority of fluid flows into a fluid transfer passage 14 and a small quantity of fluid flows directly into a distribution pan 16. The fluid is reflected again to flow in the direction parallel with the longitudinal axis of the passage 14. Consequently, a part of the fluid flows down constantly from an opening 28 over the entire length of the passage 14 and, at the same time, the remaining fluid is fed through the passage 14. After passing through the opening 28, the fluid flows under the passage 14. A dam 30 limits and averages the flow of the fluid. After passing through the dam 30, the fluid flows continuously and enters into a part of a distribution pan 16 including a fluid limiting nozzle 38.

Title: Oscillation circuit
Inventor: YORITA MASAKO
IPC: H03B5/02
Filed: 1991-08-02
Abstract: PURPOSE:To attain low power consumption of the entire circuit by combining a bipolar transistor(TR) and a CMOS TR so as to decrease a bias current, a charge discharge current and a through-current. CONSTITUTION:A crystal vibrator 64 is connected to an input terminal 61 and an output terminal 62 of an amplifier stage 60 and a feedback resistor 65, and capacitors 66, 67 are connected to the crystal vibrator 64. Then differential TRs (input active elements) 68, 69 of an amplifier stage 60 amplify a small vibration amplitude of the crystal vibrator 64 to a proper level and it is extracted by emitter follower TRs (output active elements) 70, 71. That is, since bipolar TRs are used for the input output active elements, too excess vibration amplitude is blocked to suppress a charge/discharge current. Furthermore, since output CMOS TRs 98, 99 are employed for the output active elements of the output stage 90, no bias current is required and power consumption is saved.

Filed: 1986-08-20
Abstract: PURPOSE:To make sure locking or unlocking and to eliminate fear of damaging a magnetic tape by a locking piece by providing a locking piece that can make elastic displacement and a projection for releasing locking. CONSTITUTION:A projected part 21e for releasing locking is set to a locking piece 21 at a place a little closer to a coupling part 21c for locking than the middle position of the coupling part for locking 21c and a fulcrum 21f. Accordingly, at the time of releasing, from the relation of distance ratio between the coupling part 21c for locking and fulcrum 21f and between the projected part for releasing locking and fulcrum 21f, the coupling part 21c of the locking piece 21 displaces by a required amount, and accordingly, locking can be released surely. Further, required length can be obtained for the distance between the projection 21e for releasing locking and the fulcrum 21f. As the locking piece 21 has required elastic force, relatively weak pressure is sufficient for pressing force required for releasing locking, and loading of a small-sized tape cassette 1 to the device can be made smoothly.
