Title: Phase locked loop circuit
Inventor: SATO MAKOTO
IPC: H03L7/093
Filed: 1992-10-01
Abstract: PURPOSE:To avoid the use of a phase comparator PD in a blind sector and to prevent the abnormal phenomena like the loop oscillation, etc., by applying the offset by the resistance voltage division to the single side of the output given to a loop amplifier from the PD. CONSTITUTION:A resistance R3 is put between a non-inverted input terminal of a loop amplifier 6 and an earth. Thus the input voltage VU applied to the non-inverted input terminal of the amplifier 6 can be reduced. The offset is applied to the output UOUT given to the amplifier 6 from a PD 4. When the voltage VU is reduced, the input voltage VD given to the non-inverted input terminal of the amplifier 6 works at a level approximately equal to the voltage VU. Therefore a pulse is produced to the voltage VD for reduction of the DC voltage component. Then a phase difference is caused to the input of the PD 4, and the operating area of the PD 4 having a blind sector is shifted by the phase difference. Thus it is possible to avoide the use of the PD 4 in the blind sector.

Abstract: PROBLEM TO BE SOLVED: To obtain an energy profile similar to single mode and perform imaging effectively by a method wherein multi-mode radiant ray is directed through a diffuser, whose angle is controlled, to converge the radiant ray and focus the same on a recording structural body. SOLUTION: An assembly 100 radiates laser radiant ray from the end unit of an optical fiber cable 110 through a tube 155 to converge and radiate the same to a correcting lens 145. The tube 155 is provided with a baffle 160 at the end unit of the same to prevent the penetration of the number of aperture of radiant rays, which exceed a limit. The optical diffuser 155 is provided at the vicinity of the baffle 160. On the other hand, the low-NA laser radiant ray, emitted out of the tube 155, is abutted against the lens 145 to converge the radiant ray and correct eccentric light emission. The baffle 160 restrains the dispersion of the radiant ray and avoids the reflection from the inner wall of a housing 135. A window 150 forms an aperture choking, limiting the final output, directed to the surface of a printing member 115, to the low-NA radiant ray.

Filed: 1988-11-10
Abstract: PURPOSE:To prevent the generation of crushed rice by providing a grinding whetstone piece at part or the entire length of sides facing each other in the lower half of a rice polishing cylinder with a porous wall. CONSTITUTION:Rice grains are fed to a rice grain feed device 22 through a feed hopper 21, and a main electric motor 9 and an electric motor 26 are driven respectively. The grains are fed to a spiral rotor 5 by a spiral element 23, and then are elevated to a rice polishing chamber 6 with the help of the spiral rotor 4. After this, the grains are hulled by a hulling and polishing effect generated by the rotation of a friction polishing rotor 5. In this case, the surface of the grains is ground by a grinding whetstone 35 installed in the lower half of a bran removal/polishing cylinder with a porous wall 2. Consequently, the coefficient of friction is increased, so that a friction action takes place due to a light hulling and polishing pressure. Thus the polishing degree is increased to prevent the generation of crushed rice.
