Title: Hoisting hook device for crane
Inventor: TOGAMI HARUYUKI
IPC: B66C1/34
Filed: 1994-01-31
Abstract: PURPOSE:To provide a hoisting hook device for crane, which can smoothly and securely perform the operation for hooking and unhooking a hoisting belt. CONSTITUTION:One end of a hoisting belt 31 is previously hooked on a hook main body 1. A material is hooked at an intermediate part of the hoisting belt 31, and the other end of the hoisting belt 31 is hooked on the hook main body 1 for hoisting. At this stage, an unhooking lever 3 is interposed between both ends of the hoisting belt 31. Since the lock lever 9 is pushed to open an open part 11 when the hoisting belt 31 is hooked, the operation for pulling an operation rope 7 is not required. The lock lever 9 is automatically reset by a spring 13 to close the open part 11 again and prevent the fall-out of the hoisting belt 31. After the material is hoisted and fixed to a predetermined position, a crane is operated to unload the hoisting belt 31, and the operation rope 7 is pulled. An unhooking lever 3 is turned to turn the lock lever 9 through a cam 8 and a cam shaft 12. At the same time when the end of the hoisting lever 31 is pushed up by the unhooking lever 31, the lock lever 9 opens the open part 11 to unhook the hoisting belt 31 from the hook main body 1.

Title: Character generator
Inventor: IWAKURA SADAO
IPC: G06K15/10
Filed: 1978-03-13
Abstract: PURPOSE: To increase the using efficiency of the memory by providing the memory to memorize the character information, the memory CPM to memorize the character pattern and the means to generate the signals respectively.  
     CONSTITUTION: The character information of 8 bits is stored in memory MEM to generate the character pattern, and the upper 2 bits of the 8 bits are stored in mem1. For example, with supply of the data of 01000001 to MEM as the character information, counter CNT is reset to obtain T 0  shown in the figure. The contents of CNT varies up to 001W100 by the control of the clock while the data is in MEM. For CNT, the output of gate OR 1  and OR 2  is determined by the contents of MEM and the output of gate OR 3  and OR 4  is determined by the output of CNT respectively up to 011. The output of OR 1  and OR 2  is determined by the output of CNT with CNT of 100, and the output of OR 3  and OR 4  is determined by the logic sum of the contents of mem1 and lower 2 bits of CNT. Thus, the CPM is generated via the information of 10 bits, so the using efficiency can be enhanced for the memory.
