摘要： NC programs (11a-11d) are provided for corresponding ones of movable elements for prescribed axes, and the movable elements are moved by performing numerical control processing in numerical controllers (12a-12d) based on the NC programs. A plurality of axes to be synchronously controlled are designated by a synchronous axis command (SANC) inserted in the main NC program (11a), queuing commands (WNC) are inserted in the NC programs conforming to the movable elements which include the designated axes, and the corresponding movable elements are moved and controlled by performing numerical control processing while synchronization is achieved by the queuing commands.

摘要： A numerical control apparatus for adaptively controlling a servo apparatus, wherein a load current (Ln) and a velocity (Vn) of a spindle motor (74) are used as a fuzzy input. In response to the fuzzy input, a fuzzy control means (80) effects a fuzzy inference to output a velocity control signal (Cng) for controlling the velocity of the spindle motor (74). This control of the velocity of the spindle motor (74) with the velocity control signal (Cng) makes it possible to effect a smooth velocity control.

摘要： It is possible to achieve the protection of software with reduced overhead. For example, a memory for storing an encrypted code prepared in advance and a decryptor module for decrypting the code are provided. The decryptor module includes, for example, a three-stage pipeline and a selector for selecting one output from the outputs of each stage of the pipeline. When a branch instruction is issued and subsequent inputs of the pipeline are in the order of CD′1, CD′2, . . . , the decryptor module outputs a first decrypted code by performing a one-stage pipeline process to CD′1. Next, the decryptor module outputs a second decrypted code by performing a two-stage pipeline process to CD′2, and the decryptor module outputs a third decrypted code by performing a three-stage pipeline process to CD′3 (and subsequent codes). Therefore, in particular, the overhead to CD′1 can be reduced.

The polarizing element includes a first prism having a light flux incident-side end surface on which the light flux having emitted from the optical element is incident and an emitting-side inclined surface inclined to the light flux incident-side end surface, and a polarizing element body provided on the emitting-side inclined surface, the polarizing element body transmitting first linearly polarized light out of the light flux having passed through the first prism and reflecting second linearly polarized light polarized perpendicular to the first linearly polarized light toward the first prism. The optical element is integrated with the polarizing element with an interposed adhesive layer formed on the light flux incident-side end surface. The refractive index n0 of the adhesive layer is set to satisfy the following equation: 1≦n1/n0×sin [2φ−arcsin {n0/n1×sin(θ−φ)}−2φ] where n1 represents the refractive index of the first prism, θ represents the angle between the optical axis of the light flux emitted from the light source and the light flux incident on the light flux incident-side end surface, φ represents the angle between a plane orthogonal to the optical axis and the light flux incident-side end surface, and φ represents the angle between the orthogonal plane and the emitting-side inclined surface.
