Title: Manufacture and tool for tapered thin walled can drum
Inventor: GOKIYUU ISAO
IPC: B21D39/20
Filed: 1979-11-05
Abstract: PURPOSE: To facilitate the extraction of the tapered thin walled can drum from the tool after finishing the forming work, by inserting the tool, provided with the straight tubular segmental die and the elastic straight tubular rubber, into the thin walled can drum, and by radially expanding this tool at the specified position.  
     CONSTITUTION: The cylindrical thin walled can drum 1 is inserted into the tool A till touching the upper face of the holder 4. Next, the center shaft 5 is pushed downward, the die segments 2a turn around the fulcrum 4b in a funnel shape so as to increase diameter toward the top edge 1b of the can drum 1; hereby, the can drum 1 causes a plastic deformation and is formed into a tapered thin walled can drum 1'. Next, the segmental die 2 is stopped, and the center shaft 5 is elevated while restraining the upward movement of the die 2; hereby, the die segments 2a also turn inward around the fulcrum 4b owing to the resilience of the elastic tubular rubber 3, and return to the initial position. Hereby, the tapered thin walled can drum 1' can be easily extracted from the tool A without causing friction with the tubular surface 3a.

Abstract: PURPOSE:To make it possible to cope with a high magnetic field without increasing the capacitance of a cooler and also to increase the size of a coil by a method wherein a plurality of hollow conductors are formed in sets and wound around them in spiral form on almost the same plane surface. CONSTITUTION:Two hollow conductors 3a and 3b consisting of a normal conductive material are formed in sets, wound around on an almost plane surface in spital form, and a double pancake coil is constituted. For example, one conductor 3a is continuously formed in the order of A, B, C, D, E and F, and the other conductor 36 is continuously formed in the order of a, b, c, d, e and f.

Filed: 1993-06-15
Abstract: PURPOSE:To easily synchronize processors which operate with high-speed clocks by providing an interruption informing means which generates a memory access error as a response to memory access attained by a mishit generating means when an interruption is held. CONSTITUTION:A counter 104 is made to count up each time, a core processor 100 accesses a cache memory 101. When the counter 104 exceeds a prescribed value, an indication is sent to a cache control circuit 102, which regards the access from the core processor 100 as a mishit and requests a bus control part 103 for memory access. If the interruption is held by an interruption synchronizing circuit when there is a response to this memory access, the interruption is specified as the cause of this error and then a jump to an interruption processing program is made to perform an interrupting process.
