IPC: B25J19/04
Filed: 1987-11-19
Abstract: PURPOSE:To shorten image processing time without deteriorating detecting resolution by processing the total of a picture with rough resolution at first and then processing an objective partial area with fine resolution. CONSTITUTION:An industrial TV camera 14 photographs bolts 11 in a box 10 from above and sends these video signals to a processor 15. The processor 15 applies A/D conversion to these video signals and stores the image data of fine resolution in a 1st memory 16 and the picture data of rough resolution in a 2nd memory 17 respectively. Then the processor 15 detects the contours of the bolts 11 in the box 10 based on the image data stored in the memory 17 and sets a partial area including the bolt 11 set at the highest position. Then the processor 15 reads the image corresponding to said partial area out of the memory 16 to obtain the attitude and the centroid position of the bolt 11 and sends a control signal to a robot controller 20.

Title: Exhaust valve
Inventor: ASADA TETSUO
IPC: F16K24/04
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust valve having a high vacuum breaking capability so that it can quickly break a vacuum. SOLUTION: A body 1 has a plurality of inwardly projecting ribs 9 integrated with the interior wall of a valve chamber 3, and a bottomed, approximately cylindrical float receiver 10 having a through hole 11 with a small open area in its bottom is fixed thereinside. A spherical float 12 is disposed in a free condition within the float receiver. A bottomed, approximately cylindrical flow-dividing barrier member 13 is fixed to an outflow port 5, the flow-dividing barrier member 13 having a flow- dividing portion formed in its circumferential wall 14 and a barrier portion formed by closure of a bottom wall 16, the flow-dividing portion being formed by boring a number of small gaps 15 therethrough which communicate the inside of the circumferential wall 14 to the outside.  Outside air is diffused into the valve chamber 3 from the small gaps 15 at a slow speed as it is obstructed by the bottom wall 16 of the flow-dividing barrier member 13 and decelerated, so the rate of the air being forced back on striking the bottom of the float receive 10 is reduced and the possibility of pressure buildup below the float 12 within the float receiver 10 is also reduced, with the result that increased resistance to floating of the float 12 allows rapid breaking of a vacuum.

Filed: 1994-11-29
Abstract: PURPOSE: To realize highly accurate discrimination between magnetic and nonmagnetic metals by discriminating the thickness for a plurality of materials to be inspected based on the phase shift and the attenuation level of alternating flux before and after passing through the material to be inspected. CONSTITUTION: A thickness discrimination circuit 4 comprises a phase detection circuit 41 for detecting the phase of a signal Spick detected through a receiving head 33 with reference to an output signal Stref from the coil driving circuit 32 in a transmission head 31. A detected signal Sdet is passed through a rectifier circuit 35 to produce an effective value and a comparison circuit 36 makes a decision whether two plates are superposed or not. When the signal for single sheet of magnetic metal plate, e.g. an iron plate, is compared with the signal for two sheets of metal plates, the amplitude of the signals Spick, Sdet varies significantly depending on the number of sheets and the phase varies only slightly. Wish regard to a nonmagnetic metal plate, e.g. an Al plate, the amplitude varies slightly and the phase varies depending on the number of sheets.  This constitution can discriminate between magnetic and nonmagnetic metal plates highly accurately.

Title: Sentence preparing device
Inventor: SUGAO KIYOSHI
IPC: G06F17/21
Filed: 1988-11-22
Abstract: PURPOSE:To automatically correct an error only by depressing a correcting key by providing an automatic correcting means to automatically correct the error pointed out by means of an elaborating/proofreading means and the automatic correcting key to instruct the execution of correction to the automatic correcting means. CONSTITUTION:When the correcting key of an input part 1 is inserted, first an elaborating/proofreading means 7 is activated, it checks the error in a character string, when there is the error, it notifies the error part to a user. Thereafter, when the input of the correcting key is confirmed, an automatic correcting part 6 is made access, and the error is automatically corrected. When the correcting key is not inputted, the user corrects the part according to the indicated error as usual. For example, when the error is the blurring of declensional KANA (Japanese syllabary) ending, the declensional KANA ending before and after it is checked and unified, when parentheses are not consistent, a cursor is moved to a position to be corrected, and the parentheses are inserted and corrected. Thus, the title device not only points out the error but also makes it unnecessary to require the plural complicated operations to the user, and since it automatically corrects the error only by the depression of the correcting key, the user can easily correct the error.
