Title: Grating lens
Inventor: MORI KAZUNARI
IPC: G02B5/18
Filed: 1986-03-31
Abstract: PURPOSE:To extend the minimum pitch of an unequal interval diffraction grating and widen the effective angle of field by forming the concentric circle-shaped unequal interval diffraction grating on a convex of an optically transparent body whose one face at least is formed into the convex. CONSTITUTION:A concentric circle-shaped unequal interval diffraction grating 2 whose section is saw tooth-shaped is formed on the convex of a planoconvex lens 3 whose one face is plane and the other is convex, and the parallel rays of luminous flux entering from the plane side are converged on a focus F by the lens 3. When the minimum pitch of the diffraction grating 2 is extended, the angle of diffraction of light due to the diffraction grating 2 is narrowed, and as the result, the effective numerical aperture of the lens is reduced. Simultaneously, the effective angle of field is widened.

Filed: 1985-04-08
Abstract: PURPOSE:To prevent the welding of a contact for an electromagnetic contact by inserting a resistor for charging a smoothing capacitor to a main circuit and opening the contact for the electromagnetic contactor when an abnormal detecting signal is generated. CONSTITUTION:When an abnormality detecting signal (b) is changed into 'L', an output from an AND gate circuit 10 is turned into 'L', and an output from a frequency lowering command circuit 44 is converted simultaneously into 'H' for a fixed time, thus bringing a three-phase induction motor 7 to a regenerative state. An OFF command is transmitted previously over a thyristor 3 when the abnormality detecting signal is changed into 'L', and the thyristor 3 is turned OFF. Accordingly, a resistor 4 is inserted, and contacts 1a-1b for an electromagnetic contact are opened.
