Title: Cutting tool with groove
Inventor: KINOSHITA SETSUO
IPC: B23B29/02
Filed: 1994-10-25
Abstract: PURPOSE: To prevent generation of chatter vibration by forming a groove along an axial direction of a shank in its point end part. CONSTITUTION: A groove 7 along an axial direction of a shank 1 is formed in its point end part 2. By this groove 7, a vibration transmitted from an edge point 5 of a tip 4 to a main unit part of the shank 1 is made multifarious in the point end part 2, to suppress resonance of the shank 1 by mutual interference of these vibrations. That is, the vibration of the edge point 5 is transmitted to be divided through a route propagating on a tip mounting side in the point end part of the shank 1, route propagating in an opposite side spaced with the groove 7 and a route transmitted to an opposite side passing under a bottom part of the groove 7, to generate a shift in a vibration phase by a difference between vibration characteristics based on a difference of a sectional area of each propagation route and by a difference between lengths of the propagation route, so as to damp these vibrations by mutual interference in the main unit part of the shank 1. As a result resonance of the shank 1 is suppressed to prevent a chatter vibration.

Filed: 1986-10-30
Abstract: PURPOSE:To enable inspection of power, being one of AC items, among DC items, by applying a DC positive bias voltage to a normal phase input and a DC negative bias voltage to a negative phase input sequentially to measure a pseudo-AC power. CONSTITUTION:A DC positive bias voltage with a ground potential as reference is applied to a normal phase terminal 1a to measure a DC positive voltage V1 developing at a load R. Then, a DC negative bias voltage with the ground potential as reference likewise is applied to a negative phase input terminal 1b to measure a DC negative voltage V2 developing at the load R. Then, when DC waveforms of the DC voltages V1 and V2 are combined, one cycle of an AC waveform with peak values V1 and V2 are obtained in a virtual manner. Then, V0=+ or -(P0R)<1/2> is set from a power P0 and the value V0 is compared with the values V1 and V2. This enables judgement on the propriety of a power the element needs.

If a fault takes place in a line from the station A to the station B (faulty point a), the station B detects it that it cannot depend on the station A, sends a flag F1 to the station A for the notice thereof. The station A receives the flag F1 from the station B to recognize that the synchronizing system is disconnected between the stations A and B. Thus, other line not used for the time synchronizing control is not required and the synchronizing system is surely supervised without being affected by the fault of the line.
