Filed: 1985-04-10
Abstract: PURPOSE:To improve considerably characteristics of a two-dimensional deflector by arranging optical image forming elements between the 1st and the 2nd AODs (acousto-optic deflector). CONSTITUTION:An optical image forming element 18 which has focal length F is arranged behind the 1st AOD 11 at distance F, an optical image forming element 19 having focal length F' is provided further behind it, and the 2nd AOD 12 is provided furthermore behind at distance F'. Incident light 20 is deflected in an (x)-axis direction by the 1st AOD 11 to generate diffracted light 21, which is passed through the optical image forming element 19 to become diffracted light 22 in the optical-axis direction; and the light is further passed through the 2nd optical image forming element 19 to become diffracted light 23, which is converged on the 2nd AOD 12 arranged at a focus position. The diffracted light 21 deflected by the 1st AOD 11 is therefore incident on the 2nd AOD 12 in any case. The diffracted light 23 incident on the 2nd AOD 12 is deflected in a (y)-axis direction to obtain diffracted light 24.

Title: Magnetic medium
Inventor: OTAKE MITSUYOSHI
IPC: G11B5/708
Filed: 1986-04-04
Abstract: PURPOSE:To obtain the title magnetic medium having excellent wear resistance and a long service life and which is never broken during traveling by incorporating polypropylenetriol into the magnetic coated film. CONSTITUTION:The magnetic medium has a magnetic coated film contg. 1-20wt% polypropylenetriol having 3,000-4,000mol.wt. at room temp. The polypropylenetriol having 3,000-4,000mol.wt. has excellent lubricity, dispersibility and antistatic effect and hence the wear resistance of the magnetic medium is improved. When <=1wt% polypropylenetriol is used, the effect is decreased and a decrease in the lubricant on the tape surface by cutting is not sufficiently replenished from the inner surface of the tape. Conversely, when >=20 wt.% is used, the surface becomes sticky, hence dust is deposited from the outer surface, the magnetic coated film layer is not satisfactorily stripped from the nonmagnetic base and the success probability in autoloading is liable to decrease.

IPC: B02C1/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To economically produce aggregate used for construction and civil engineering works from crushed rock and crushed waste concrete with simple equipment by repeatedly making grinding weights fall to a material to be ground moving along a flow passage from above it. SOLUTION: When a mill 1 is driven and a material to be ground W is fed onto a grinding trough 2 from a throw-in hole 8, the material to be ground W is moved in a flow passage 3 to the downstream side thereof. At this time, grinding weights 10 rise and fall by the rotation of a driving shaft 15, causing the material to be ground to be ground. On this occasion, in the case mortar is removed from crushed waste concrete and coarse aggregate is ground and recovered, plural aggregates stuck on each other are made in a state of one coarse aggregate in the upstream part of the grinding trough 2 by rather light grinding weights 10. And as they are moved to the downstream side, mortar is removed from the individual coarse aggregates by the rather heavy grinding weights 10 and the crushed mortar is moved to the downstream side to separate it from the coarse aggregates.

Abstract: PURPOSE:To improve the operability and the reception performance by arranging a JSB decoder to a receiver together with a satellite broadcast reception circuit and using a PCM demodulation circuit in common thereby receiving a scramble signal and a usual satellite broadcast signal not scrambled. CONSTITUTION:A digital voice signal is extracted from a broadcast signal received by a satellite broadcast reception circuit 2 and given to a processing circuit 14, in which the processing such as QPSQ, bit interleave and error correction is implemented. The voice data signal is given to a changeover circuit 12 and a JSB decoder 16.
