Title: Method for judging welding quality of connectively and welded part of steel strips
Inventor: SATO YUJI
IPC: G01N21/892
Filed: 1989-12-12
Abstract: PURPOSE:To accurately judge the quality of welding by introducing the reflection image of the light of a welded part subjected to judgement to compare and collate the same with the preliminarily stored reflection of image of the light of a good welded part in a control apparatus. CONSTITUTION:When an upper steel strip 1 and a lower steel strip 2 are held between upper and lower electrode wheels 5, 6 to supply a current to both electrode wheels 5, 6 under pressure, the non-bonded parts 3 of the upper end lower steel strips 1, 2 to form a bonded part 4. A stroboscope 8 and a camera 7 are arranged to the outer surface of the welded part after welding and the reflection image of the surface of the welded part is introduced into a controller 10 through an image processor 9 processing an image into a binarized signal. The reflection image of the surface of a good welded part is preliminarily stored in an image memory device 11 to perform the comparison of both images by the controller 10 and, when the image introduced into the controller 10 is equal to the preliminarily stored image, a good welding state is displayed on a good welding display 13 and, when both images are not equal, an inferior welding state is displayed on an excessive heat input display 12. When a slit appears, too little heat input is displayed on a too little heat input display 14. As a result, even when the steel strips are passed in spite of welding inferiority, the breaking of the passed steel strips is not generated and accurate quality can be judged.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of surface stain on an image by preventing the incomplete recovery of restuck toner by making a developing effective width longer than the length of a cleaning member in an axial direction so as to make the length of the cleaning member in the axial direction within the developing effective width which is the length of a range where developing is actually performed in the axial direction of a developer carrying and feeding member. SOLUTION: The developing effective width H is set to be longer than the length L of a cleaning roller 12 in the axial direction so as to make the length L of the cleaning roller 12 in the axial direction within the range of the developing effective width H. Thus, even if the cleaning roller 12 rattles in the axial direction in the midst of rotating operation and the toner is restuck to the end part area D1 of a photoreceptor 1 in the axial direction from the cleaning roller 12, the toner in its area is recovered by the roller 5 without hindrance because the developing effective width H of the roller 5 exists. Even if the cleaning roller 12 moves to rightward by rattling in the axial direction and a toner stuck area is made on the side of a right end, it is similarly recovered without the hindrance.

Title: Recorder
Inventor: HARA TOSHIMASA
IPC: B41J2/30
Filed: 1990-11-27
Abstract: PURPOSE:To keep driving current of recording element substantially constant so as to make recording density substantially constant by controlling current value to flow to the recording element according to the temperature of a current detecting resistance connected to the recording element in series. CONSTITUTION:When a current quantity flowing to a hammer 211 increases, an electric potential of a detecting resistance Rs rises. When this electric potential rises higher than an electric potential of a minus input terminal of a comparator 103, an output signal level of the comparator 103 becomes high level. Accordingly, a transistor Q5 becomes an OFF state and power to be supplied to the hammer 211 is stopped. When the electric potential of the detecting resistance Rs decreases again, the output of the comparator 103 reverses again to have a low level and transistors Q5 and Q6 become ON state. When the temperature of the detecting resistance Rs rises, this temperature is detected by a temperature detecting circuit 104, either of transistors Q1-Q4 is made to be ON by a reference electric potential selecting circuit 105, and a reference electric potential of the minus input terminal of the comparator 103 is changed. When the temperature of the detecting resistance Rs rises, the reference electric potential of the comparator 103 decreases.

IPC: B25J9/16
Filed: 1989-12-12
Abstract: PURPOSE:To realize an efficient processing by dividing instructions to be treated into an instruction group which needs time for the processing and an instruction group which can promptly be executed and multiplex-processing the instructions. CONSTITUTION:Among robot control instructions, the instruction which needs the processing by waiting for the termination of a robot operation is transmitted by a first communication line 3 and the prompt execution instruction except for said instruction is transmitted by a second communication line 3'. Then, they are stored in first and second temporary storage parts 8 and 8'. An analysis part 9 reads the subsequent instruction when the execution of the instruction by an execution part 10 terminates. Since a robot control instruction from the second temporary storage part 8' is the prompt execution instruction, the processing corresponding to the instruction is immediately processed in the analysis part 9. Thus, the instruction can efficiently be processed and the probability of the occurrence of a deadlock in the execution part 10 is reduced.

Abstract: PURPOSE:To realize high output and, at the same time, suppress the manufacturing cost at a low level by providing a main exhaust valve for a low speed range and a main exhaust valve for a high speed range that change the exhaust gas timing and a pair of auxiliary exhaust valves that face to an auxiliary exhaust port beside a main exhaust port and change the sectional area of a passage. CONSTITUTION:A main exhaust valve 15 for a low speed range and a main exhaust valve 16 for a high speed range of parallel displacement type that change the exhaust gas timing are provided, and a pillar-shaped auxiliary valve 18 is provided on the upper side of an auxiliary exhaust passage 14, and all exhaust valves are fully closed at the time when an engine 1 is at a low speed. When rotational speed of the engine exceeds a set rotational speed (during medium speed time) the main exhaust valve 15 for a low speed range and the auxiliary exhaust valve 18 are opened, and the main exhaust valve 15 for a high speed range is opened after that. Since the exhaust gas timing in a main exhaust passage 13 is quickened by a large amount of change when the main exhaust valve 15 for a low speed range is opened, it approaches the substantial time to exhaust gas of the engine 1, thereby enhancement of output in a medium speed range can be attempted.
