Title: Tool holding device
Inventor: HIDESHIMA MASABUMI
IPC: B23C5/26
Filed: 1987-12-09
Abstract: PURPOSE:To make it possible to perform a completely-unmanned automatic tool exchange by rotating a petaline clamp at a specified angle in both normal/ reverse directions together with a draw bar when the petaline clamp is clamped or unclamped. CONSTITUTION:The advance or retreat of a draw bar 2 in the axial direction is accompanied with the rotation of a petaline clamp 3 due to the operation of a movement converting mechanism. Since the movement direction when the draw bar 2 moves forward is opposite to that when it moves backward, the rotation of the petaline clamp becomes opposite in direction. And also, since the momentum of the draw bar 2 is always constant, rotary angles of rotations in both normal/reverse directions become equal. As a result, the rotary direction of the petaline clamp 3 is set so as to rotate from a petaline hole 22 to a pulling/inserting point when unclamped, and rotate from the pulling/ inserting point to an engaging point with a cutter 20 when clamped. Consequently, the cutter 20 is shifted just below a spindle from a stock point, and combined with a conveyer provided with a function for straight shifting the cutter in a spindle axial direction to insert or pull the petaline clamp 3, so that the completely-unmanned exchange of an automatic tool can be performed.

Title: Phase synchronizing oscillation circuit
Inventor: YASHIKI MINORU
IPC: H03L7/08
Filed: 1988-12-12
Abstract: PURPOSE:To reduce the fluctuation of the output frequency sepite the input of clock signals of different phases by connecting an LPF to a phase comparator by performing the control so as to secure the synchronization between the phase of the output signal of a frequency divider and the phase of a switched clock signal. CONSTITUTION:When a switch signal CH changes, a selector 1 selects a reference clock CK2 having a 36 deg. phase difference out of a reference clock signal CK1 and sends it to a phase comparator 7. An AND gate 17 secures an AND between reference clock signal S1 and S2, and outputs a clock signal S3. A frequency divider 13 is cleared by the output signal S4 of a pulse width conversion circuit 19 and restarts a dividing action when no pulse of the S4 exists any more. Then the phase of the output signal S5 is synchronous with the phase of the signal CK2. The output of the comparator 7 gets out of a synchronizing state in a moment right after the switch of clocks. In this case, however, the fluctuation of the output frequency can be suppressed for a voltage control oscillator 11 since the output change of an LPF 9 requires a sufficiently long time compared with a phase comparison period.

Abstract: PURPOSE:To shorten file access time by calculating the number of times of access and the frequency of access of respective file, duplicating the file whose number of times of access or frequency of access exceeds a normal value on the unused area of a magnetic tape, and making access to duplicated file data hereafter. CONSTITUTION:The present date information is obtained from a clock circuit 4, and the number of days elapsed from the registration day of targeted index data is calculated, and the access frequency is calculated by dividing the number of times of access by the number of days elapsed, and it is checked whether or not the access frequency exceeds a constant value. And the file whose number of times of access or frequency of access exceeds the normal value is duplicated on the unused area of the magnetic tape, and the duplicated file data is made accessed hereafter. Therefore, a tape feed time can be shortened since the file with high access frequency is concentrated on the specific storage area of the magnetic tape. In such a manner, it is possible to shorten the file access time.
