IPC: H01R39/00
Filed: 1993-04-15
Abstract: PURPOSE:To reduce the quantity of parts and the manhour of an assembly work by forming an insulation layer on a rotary plate or a fixed plate as an integral part. CONSTITUTION:Regarding a fixed plate 6 and a rotary plate 7 to compose a plurality of conductive contact pairs 3 externally coupled to a spline shaft 2, an insulation layer 8 is formed in advance, for example, on one side of the plate 7 as integral part thereof. According to this construction, an electrical insulation ring conventionally handled as an independent component can be changed from an object for single item handling to an object for handling as the integrated accessory of the plate 7. Thus, the quantity of parts and the manhour of assembly can be reduced. At the same time, a slidable contact section and area can be reduced to eliminate a factor leading to dielectric breakdown as much as possible, and maintain stable performance over a long term.

Title: Radiographic image information reader
Inventor: HORIKAWA KAZUO
IPC: H04N1/04
Filed: 1986-04-17
Abstract: PURPOSE:To prevent the deterioration in the picture quality of a reproduced picture by providing a sharpness adjusting means receiving the output of a light quantity detecting means and a control means reducing the sharpness in response to the deterioration in the stimulating light quantity. CONSTITUTION:The output S1 of a light quantity detector 33 detecting the light quantity of a deflected laser beam 13 at a position at the outside of the effective scanning range is inputted to a control circuit 32. The control circuit 32 outputs an actuator drive control signal S2 in response to a light quantity signal S1 to drive and control an actuator 31 so as to extend the beam diameter as the light quantity of the laser beam 13 is lowered. When the beam diameter of the laser beam 13 is extended, since an accumulative type fluorescent material 10 is scanned by a thicker stimulating light beam, the sharpness of a reproduced radiant ray picture is lowered. Thus, the granular deterioration in the reproduced radiant ray picture is suppressed and the deterioration in the picture quality is prevented.
