Title: Chuck device
Inventor: KOBAYASHI RICHIKO
IPC: B23B31/22
Filed: 1994-03-25
Abstract: PURPOSE:To attach and detach a drill bit in a single operation, and prevent idle run of the drill bit. CONSTITUTION:A small hole 9C in which a spherical stopper 12 can move, is formed on a hollow chuck body 9, a first groove 10A into which the spherical stopper 12 enters, is formed on the outer surface of a drill bit fixing hardware 10, and a second groove 11A into which a part of the spherical stopper 12 is formed on the inner surface of a sleeve 11 outside the chuck body 9. When the small hole 9C conforms to the second groove 11A, the drill bit fixing hardware 10 is released from the chuck body 9, since the part of the spherical stopper can enter into the second groove 11A. On the other hand, the second groove 11A does not conform to the small hole 9C, the drill bit fixing hardware 10 is not released from the chuck body 9, since the part of the spherical stopper 12 moves to the first groove 10A, and the movement of the spherical stopper 12 is prevented by the sleeve 11.

Title: Data processing device
Inventor: HANATANI SHIYUUICHI
IPC: G06F9/38
Filed: 1982-05-10
Abstract: PURPOSE:To eliminate the disturbance of a pipeline control due to branch instruction to process branch instructions in a high speed, by obtaining branch addresses of branch instructions to read branch destination instructions from an instruction private memory. CONSTITUTION:An instruction group read out from an instruction private cache memory 2 is stored in a buffer register 4. Before this storage, an instruction arranging circuit 5 arranges respective instructions to read out the instruction group from the memory 2. An instruction decoding circuit 16 decodes instructions of the output from the circuit 5. When a branch instruction is decoded, an update monitor circuit 17 detects whether a register, which generates the branch address of the branch instruction, is updated before the execution of the branch instruction by a preceding instruction or not. If it is detected that this register is not updated, a branch address calculating circuit 18 obtains the branch address of the branch instruction to make it possible to prefetch the branch destination instruction.

As the dye, any dye whose color changes (coloring, discoloring) in an oxidizing-reducing state may be used and a dye having a color in the oxidized state and being colorless or light-colored in the reducing state is pref. As the reducing agent, any agent reducing the dye to change the color can be used but a reducing agent, for example, a reducible saccharide hardly oxidized by oxygen in air at room temperature is pref. When recording is applied to the recording layer 2 by a thermal head 3, the color of a heated region changes, resulting in printing a character 4. The printed character 4 absorbs oxygen in air by being left as it is to return to the original color and becomes the same color as a ground color 5 and, as a result, recording data is naturally erased.
