Title: Storage device
Inventor: KAWAKAMI TAKAHITO
IPC: G06F13/16
Filed: 1986-11-11
Abstract: PURPOSE:To reduce steps that a CPU controls for reading data and to shorten processing time by permitting hardware such as a register, a selector and a gate to execute operations when a pointer is read out of a memory. CONSTITUTION:While a signal P is outputted, a signal 60 showing whether accessed data in the memory 1 is the pointer or not becomes 'H'. Only if the signal 60 becomes 'H' during a period from t1-t3, an address/data decision circuit 6 outputs signals 61-64. The initial pulse of the signal 64 prompts a signal on a data bus 3 to be written in the register 7. While the signal 62 is 'H', a signal 22 being an output from the register 7 is inputted as a signal 23 to the memory 1, and a signal D is outputted as a signal s3 to the data bus 3 from the memory. By the 2nd pulse of the signal 64, the signal D on the data bus is written in the register 7. The hardware can execute the operations that a program control executes conventionally, whereby the control steps for processing can be reduced and the processing time is shortened.

Title: Tool cut-depth control device for dual spindle machine
Inventor: KOARASHI MASAAKI
IPC: B23Q5/32
Filed: 1985-11-30
Abstract: PURPOSE:To aim at efficiently and accurately adjusting the tip of a tool, by operating a rotary means for rotating outer and inner spindles to change the rotational phases of outer and inner spindles under automatic control. CONSTITUTION:The centers of outer and inner spindles 2, 3 are made to be eccentric by an eccentricity (e), and a tool fitting hole 4 is also made to be eccentric with the inner main spindle 3 by an eccentricity (e). Accordingly, the cut depth (a) is changed in accordance with the following equation, a=e(1-costheta), where theta is a rotational phase angle. When a motor 10 rotates a thread shaft 6, the outer spindle 2 and the inner spindle 3 are rotated reversely to each other, due to the meshing between gears 5a, 5b having reversely twisted angles and gears 7, 9 so that the rotational phase angle theta is determined. When a desired cut-depth is inputted at a control means 14, the rotational phase angle is calculated, and a motor rotating angle (theta) giving theta is delivered to a controller 13. The controller 13 rotates the motor 10 in accordance with the rotational angle (theta). Thus, the tip of a tool may be automatically moved to a predetermined position, and therefore, it is possible to efficiently and accurately adjust the position of the tool tip.
