Title: Recording/reproducing device for recognizing focusing state
Inventor: DANG LIEU-KIM
IPC: G11B7/09
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To recognize a focusing state easily and at low costs by splitting a reflected light beam into normal and abnormal fractional beams by a double refraction element and estimating the focusing state of the scanned light beam based on the sectional state of the abnormal fractional beam. SOLUTION: In this recording/reproducing device, a reflected light beam 15 converged after passing through a condenser lens 13 is projected, by a parallel flat plate 23, on a double refraction element formed thereon. In the parallel flat plate 23, the reflected light beam 15 is split into normal and abnormal refractional beams 25 and 26. The normal and abnormal refractional beams 25 and 26 are projected on a detector 18. A focusing error signal is produced by using the abnormal refractional beam 26 for evaluation.

Filed: 1991-11-29
Abstract: PURPOSE:To provide the digital filter whose coefficient storage capacity is reduced by providing an amplifier section amplifying a signal passing through the filter and whose gain is variable and an adder section adding a signal outputted from the amplifier section and an input signal to the filter. CONSTITUTION:The filter consists of four delay sections 11-14 delaying a sampling period signal, 5 coefficient multiplier sections 15-19 multiplying coefficients A-E, an adder section 20, an amplifier section 21 whose gain is G, an adder section 22 and a control section 22.

Title: Backup reactor shut-down device for high-temperature gas-cooled reactor
Inventor: IKEDA TATSUMI
IPC: G21C9/02
Filed: 1987-12-17
Abstract: PURPOSE:To effectively recover control elements by forming the shape in the bottom part of a control element insertion hole to a tapered shape, the min. hole diameter of which is the hole diameter at the bottom end thereof, so that the hole diameter at the bottom end is identical with the hole diameter of the recovering pipe of a recovering device for the control elements. CONSTITUTION:The shape in the bottom part of the control element insertion hole 19 formed in a reactor core 2 has the tapered part 10b reducing gradually toward the bottom end to minimize the hole diameter of the bottom end 19a thereof. The hole diameter of the bottom end 19a thereof is nearly similar to the hole diameter of the recovering pipe 22. The inlet part of the recovering pipe 22 is formed to a bell-mouth shape at the front end in order to decrease the pressure drop. Gas flow passages 25 are generated in the insertion hole 19 when the control element recovering device is operated. The control elements 14 are sucked into the recovering pipe 22 by being entrained in the flow and are thereby recovered. Since a nozzle, etc., are not attached to the recovering pipe 22, the effective flow passages 25 are generated without narrowing the flow passages 25 and without increasing the blower load. The elements 14, on arriving at the bottom, move along the slope of the tapered part 19b and head toward the bottom end 10a. The control elements are thus easily recovered.
