Filed: 1980-03-07
Abstract: PURPOSE:To uniform the wear of an electrode at its tip and assure machining accuracy even with the uniformly worn electrode, by controlling the machining feed velocity through checking the conditions of machining gap with a low voltage pulse. CONSTITUTION:As programmed and before deterioration of machining conditions is found by a detector 8, an additional axial feed for a minute distance (d) is given to a working electrode 2 while it traverses from P' to Q', so that the unworn bottom 2b of the electrode 2 is purposely worn. A control system for pulse motors 17, 21 gives profile machining according to an NC program, controls the feed velocity in accordance with the output from the detector 8 and keeps the machining gap (g) adequate as designed, while another control system for a pulse motor 19 controls the notching movement at a preset turning point and the Z-axis gap (g). This can assure machining accuracy with the uniformly worn electrode.

Title: Optical isolator
Inventor: KAMATA OSAMU
IPC: G02F1/09
Filed: 1985-02-15
Abstract: PURPOSE:To obtain a high isolation ratio by making the growing direction of a crystal of an optical isolator coincide with the optical axis direction of the optical isolator. CONSTITUTION:The growing direction of crystal used for an optical isolator is made coincide with the optical axis. A distortion by a composition variation which follows a growth fringe is generated due to a distortion in case when crystal layers having each different lattice constant have been superposed. A stress sigma is applied between the crystal layers having each different lattice constant, and a double refraction is generated through an optical elastic effect. Accordingly, when a light is made to pass through vertically in the crystal growing direction, a linearly polarized light becomes elliptical due to this double refraction, and deterioration of an extinction ratio is shown. In case when a light is made to transmit through in the crystal growing direction, a stress on the growth surface is generated uniformly, negated each other, and becomes a state that there is no stress equivalently, therefore, no double refraction is generated.
