Abstract: PURPOSE:To reduce the pause period of line by providing a recognition stage between the main buses and judging termination or not termination of line junction and distributing the result to each junction apparatus. CONSTITUTION:In the recognition stages A13, B14, if the lead frame in such position has completed the line junction, it is sent to the accommodating part 9 through the main buses A11, B12. If line junction is not yet completed, the junction device not operated is selected by the signal lines 16, 17 and the frame is sent to the main bus A13 in order to send the lead frame to said junction device. For example, if the device B7 is in the waiting condition, it is inrailed from the main bus 11, and if the device C8 is in the waiting condition, the lead frame is transferred to the junction device C8 through the route of A11  B14   main bus C12   inrail 8a. According to this structure, the pause period of line as a whole can be reduced remarkably and processing capability increases.

Title: Pneumatic tire and die for vulcanizing the pneumatic tire
Inventor: IMAI YOSHIMASA
IPC: B29K21/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent rubber breaks or cracks from being caused on a tread rubber around a main groove. SOLUTION: After vulcanization, a die for vulcanization is released to take a tire 21 out. At this moment, main projections 44 and 45 and the tire 21 are relatively moved in its tire axis direction, thus those projections 44 and 45 push and deform the side wall of the main groove 41 in a direction which causes it to driftaway from the read center S. However, since the side of tip of the main groove 41 which causes the main projections 44 and 45 to drift away from the tread center S, is substantially flat, the movement does not give an excessive pressured deformation to the side of the main groove 41.

Abstract: PURPOSE:To prevent hand blur or the like at a faster shutter speed suitable for still picture image pickup by controlling the shutter speed and the aperture of a image pickup element based on a start command of still picture image pickup and an output of a detection means. CONSTITUTION:When a release button 17 is half-depressed (1 stage ON), a control circuit 18 reads aperture information from an aperture read circuit 15. Whether or not the aperture is open is discriminated, and when the aperture is not open, the shutter speed and the aperture are set based on the relation between the shutter speed and the aperture. When the aperture is open, an AGC gain is read, whether or not the AGC gain is maximum is discriminated and when not maximum, the shutter speed is set based on the relation between the shutter speed and the AGC gain. That is, based on the aperture or the AGC gain, when the pickup is available even with the shutter speed set higher, the shutter speed is controlled suitable for still picture image pickup. When the release button 17 is half-depressed, the setting of the shutter speed is continued and when the release button is turned off, the mode restores to the normal image pickup.
