Filed: 1987-02-13
Abstract: PURPOSE:To identify a reception signal without any error by extracting a rough clock signal from N sets of data, using a synchronizing clock amplified by a broad band amplifier and controlling the delay so that the N sets of rough clock signals are made in phase. CONSTITUTION:Each rough extraction clocks extracted by timing extraction circuits 110(1)-110(N) are inputted to phase comparators 111(1)-111(N). ON the other hand, a synchronizing clock from the transmission section amplified by a broad band amplifier 107(N+1) is inputted to the N sets of the phase comparators 111(1)-111(N) as a reference phase synchronizing clock. The delay quantity is changed in the optical delay circuits 108(1)-108(N) by using the delay control signal inputted from the phase comparators 111(1)-111(N) to vary the phase of the reception information in the optical signal state. Thus, a synchronized data between parallel reception information from which delay variation and skew removed thereof is sent to the reception section 113.

Title: Furnace cylinder smoke tube boiler equipment no blowdown
Inventor: SHIODA AKIO
IPC: F22G7/10
Filed: 1995-01-09
Abstract: PURPOSE: To achieve higher efficiency with the conserving of both water and a fuel by turning water, so far discharged outside as intermittent and continuous blowdown in a steam boiler, to steam by superheating to utilize the steam thus obtained. CONSTITUTION: Water heated excessively from a lower water chamber 3 of a furnace cylinder smoke tube boiler is sent to a superheater 4 arranged in a rear part smoke chamber 2. The superheater 4 is heated by a high temperature combustion gas from a combustion chamber 1 and turns the water sent from the lower water chamber 3 to steam by superheating using the heat to be sent to a steam part 5. The steam part 5 serves as a steam separator of a once-through boiler to utilize the steam alone. In other words, the water heated excessively so far discharged as intermittent and continuous blowdown in the furnace cylinder smoke tube boiler is utilized as steam. This achieves higher efficiency with the conservation of water and a fuel.

Abstract: PURPOSE: To set the original at an accurate timing by once driving only the belt drive device when the index part provided to a conveying belt is not in the specified position.  
     CONSTITUTION: An original sensor 7 and belt position sensor 11 are connected by way of gates U1WU8, 1st, 2nd latch circuits 14, 15 to a body control circit 16. As a result of this, if the slit or notch 10 being the index part provided to a conveying belt 4 deviates in position from the belt position sensor 11 owing to the position deviation of the conveying belt 4, the output of the 1st latch circuit 14 is inputted as the signal for temporarily stopping the copying operation to the body control circuit 16 when a print switch is pushed. Also, this causes a belt drive clutch CL1 to be energized and further the energizing of a solenoid CL2 to be inhibited so that the inlet gate 3 is held closed and the conveying belt 4 is turned in the current position, after which the input gate 3 is opened. Hence, the conveying belt 4 is started always from the correct position and the original is set in the specified position of the platen glass at a correct timing.

Abstract: PURPOSE:To prevent leakage of heat pipe and permit to recognize that the heat pipe is being used under dangerous temperature by burying a low melting point metal into the outer peripheral surface of a sealed vessel constituting the heat pipe. CONSTITUTION:One part of the outer peripheral surface of the vessel 6 for the heat pipe 5 is provided with a thin section 7 and the low melting point metal 8 is buried into the thin section 7. When the heat pipe 5, which uses water as dangerous temperature operating liquid, is used under about 240 deg.C, heat of heated steam in the vessel 6 is transferred to the low melting point metal through the thin section 7. In case the low melting point metal 8 is constituted of solder or the like, which is softened and molten at a temperature lower than 240 deg.C, the low melting point metal 8 deforms or drops before the steam pressure in the vessel 6 is increased excessively, therefore, leakage of the heat pipe 5 will never be caused while it may be recognized that the heat pipe 5 is being used at the dangerous temperature.
