摘要: A highly accurate position detection is performed by the use of a magneto-resistance effect element such as a TMR element. At least two magnetic detecting elements 21-1 and 21-2 are provided to detect leakage magnetism from a scale 11 having a magnetic signal magnetically recorded thereon, and to output a recording signal of a position where the leakage magnetism is detected. The at least two magnetic detecting elements 21-1 and 21-2 are disposed side by side in a direction y perpendicular to a direction x of scanning the scale 11 and also disposed at positions approximately equidistant from a magnetic signal recording surface of the scale 11.

摘要: The invention prevents chips from being scattered. Provided is a cutting tool cover set to a cutting tool which includes a hollow shaft body and at least one insert attached to an end face of the shaft body and cuts by bringing the insert into contact with a work while rotating the shaft body. The cutting tool cover includes: a body portion fixed to a top end portion of the shaft body; and an extension portion extended outward from the circumferential edge of the body portion in the entire circumference of the top end portion of the body portion to cover the surface of the work.

摘要: To provide a displacement detection apparatus capable of detecting a displacement in the height direction of a member to be measured, with a high precision, and also capable of performing a high-speed and stable measurement. A first light flux L1 serving as object light is caused to enter a member to be measured 5, and reflected light thereof is caused to enter again the member to be measured 5 after being diffracted by a first diffraction grating 7. Then, the second-time reflected light of the first light flux L1 by the member to be measured 5 is diffracted by a second diffraction grating 9. By diffracting the first light flux L1 by the second diffraction grating 9, a change of the optical path length caused by tilting of the member to be measured 5 is cancelled.

摘要: A magnetism detecting element detects a leakage magnetism from a scale, on which a magnetic signal with a constant period is recorded, and a relative position between the scale and the magnetism detecting element is detected. The magnetism detecting elements are arranged, along a detection direction of the magnetic signal relative to the scale, in a pattern with a pitch of 1/2n (n is a prime number of 3 or more) of a wavelength λ' of a signal output by the element. Furthermore, as the pattern for cancelling m odd-order harmonics, the m-th power of 2 magnetism detecting elements are arranged within a range in which a pitch distance L of the magnetism detecting element farthest in the detection direction is expressed by L= (λ'/2) × (1/3+1/5+1/7+... 1/(2m+1)).
