Abstract: PURPOSE:To set a distance between a floodlight and a photodetector over a wide range so as to detect a reference signal for synchronization. CONSTITUTION:A light projecting control circuit light projecting means 3 of a floodlamp 1 applies the reference signal for synchronization to LED (light projecting element) 7a and 7b and successively applies light projecting signals to LED 7a-7e at prescribed light projecting timing. The reference signal for synchronization sets the first cycle at a high level and sets the second cycle at a low level. A photodetector 2 detects the reference signal for synchronization with a photodetection control circuit 13 based on the photodetection signal of output time corresponding to a photodetection level from photodetection units (photodetectors) 8a and 8b, generates a photodetection timing signal for two cycles and inputs a photodetection signal corresponding to a floodlight signal for detection. Since the amount of photodetection is made excess or lacked at the photodetection unit 8a or 8b with the reference signal for synchronization at one level, it is enough to detect any one of reference signals for synchronization at two levels even when no photodetection signal can be provided and therefore, the arranging distance between the floodlamp 1 and the photodetector 2 can be enlarged.

Abstract: PURPOSE:To decrease the number of replacement cycles of a cutter push blade for a nuclear reactor measuring pipe to aim at shortening the time of cutting work by supplying pressure water or the like into cylinder mechanisms for a grindstone so as to press the grindstone against to a worn push blade at a regulated pressure, and by reciprocating the push blade to grind the latter. CONSTITUTION:A push blade 2 having been worn after cutting nuclear reactor measuring pipes is attached to a flanged rod 72 in a push blade polishing device laid on a fuel replacement plate form after the cover of the latter is opened. Then, after closing the cover, pressure water is fed and discharged alternately to and from cylinder chambers 18, 19 in a reciprocating cylinder mechanism 3 from an underwater pump on the fuel replacement platform. Thereby the push blade attached to the flanged rod 27 is reciprocated in the axial directions of pistons of both cylinder mechanisms 11, 12. When pressure water is fed into a cylinder chamber 33a in a grind stone cylinder mechanism 5, a cylinder block 31 is pushed forward so that a grindstone 4 is pressed against the push bar 2 which is therefore reciprocated on the grindstone 4 so as to be polished. After roughly grinding the blade, the grindstone 4 together with a grindstone receiver 36 is replaced with a finishing grindstone for final polishing.

Title: Tri-state ecl circuit
Inventor: NAKAHARA SOUTAROU
IPC: H03K19/0175
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide an output of a Z state independently of an input level by integrating constant current sources into one source so as to nearly halve the power consumption. SOLUTION: When a state control terminal CT is set to an L level, a p- channel MOS transistor(TR) P1 is made conductive and a 3rd bipolar TR Q3 is nonconductive. In this case, the circuit acts like an ECL inverter circuit that employs a parallel combined resistance of resistors R2, R3 as resistance to obtain a logic level. On the other hand, when a status control signal terminal CT is set to an H level, the p-channel mOS TR P1 is made nonconductive and the 3rd bipolar TR Q3 is made conductive. In this case, since the 3rd bipolar Tr Q3 is made conductive, no current is supplied to a resistot R3 and a current is supplied to a resistor R2 only and a voltage drop is produced across the resistor R2, then a Z state is outputted.
