Title: Level controller for drain tank of feedwater heater
Inventor: TSUJI HIROSHI
IPC: F22D1/32
Filed: 1987-09-18
Abstract: PURPOSE: To suppress fluctuation of the water level of a high-pressure drain tank, by adding a signal, where a deviation signal between the drain flow command signal of each other water level adjusting valve and its real drain flow command signal is added to the drain flow command signal outputted to each water level adjusting valve, as a control signal to the water level adjusting valve. CONSTITUTION: In case that abnormality occurs in either of normal water level adjusting valves 12a and 12b, for example, in the normal water level adjusting valve 12a and it operates in close direction, a normal water level adjusting valve drain flow signal e1 deceases, the deviation signal f1 of the drain flow of the ordinary water level adjusting valve increases. Accordingly, the drain flow command signal of the normal water level adjusting valve 12b increases by that amount, and that water level adjusting valve 12 is actuated in open direction. That is, the normal water level adjusting valve 12b on normality side works to compensate the operation of the normal water level adjusting valve 12a on abnormality side.  Conversely, in case that the normal water level adjusting valve 12a on abnormality side operates in open side, the normal water level adjusting valve 12b on abnormality side operates for compensation in close direction.

Abstract: PURPOSE:To generate a ridge line on a ridge surface to a ridge line to be rounded with a small data amount by deciding the direction of a vector so that a tangential plane at the both ends of the ridge line to be generated can be coincident with a tangential plane before rounding, and deciding the size of the vector based on a rounding amount at the both ends of the rigid line to be rounded. CONSTITUTION:The vicinity on an adjacent face to the ridge line to be rounded is generated by adding the vector to apply offset (correction) in a direction crossing the vicinity to be rounded to a point on the vicinity to be rounded. The direction of the vector to apply the offset in the direction crossing the vicinity to be rounded is generated from the vector of the offset at the both ends of the ridge line on the adjacent face to the ridge line to be rounded, and decided so that the tangential plane at the both ends of the ridge line to be generated can be coincident with the tangential plane before rounding. Thus, regardless of the shape of the ridge line to be rounded, the ridge line on the adjacent face to the ridge line to be rounded can be generated with the small data amount.

Abstract: PURPOSE:To obtain a thermal head of which a heating line has a also flatness since distortion of a ceramic substrate is sufficiently corrected by uniform heat transmission for heat radiation by a method wherein a specific pitch irregular part is provided to both surfaces of a heat transmission sheet interposed between the ceramic substrate and a radiation plate. CONSTITUTION:An irregular part of almost one dot pitch or under of a heating element in pitch is provided to both surfaces of a heat transmission sheet 11. When the heat transmission sheet is combined with a radiation plate 1 and a ceramic substrate 2, its crest part 11b is crushed by its elasticity to press the radiation plate 1 and the ceramic substrate and besides, a bottom part 11c remains. Therefore, heat conduction is uniformly performed by uniform collapse of all the crest part 11b and besides, even though the ceramic substrate 2 is distorted 22, the distortion 22 is corrected by pressing of the crest part 11b to flatten a heating line 21. Further, bubbles remaining on both surfaces of the heat transmission sheet 11 pass through a groove 11a exposed to an edge surface of the ceramic substrate 2 and the remaining bottom part 11c, are exhausted outside by collapse of the crest part 11b, and no bubble remains over a wide range. Therefore,the uniform heat conduction is obtained.

Abstract: PURPOSE: To enable empty load units supplied to a pallet tower from the rear to be periodically pushed into a filling station while load units to be pulled out of the pallet tower on the rear by periodic vertical movements of stackable units of a filled pallet along an elevator. CONSTITUTION: An elevator 54b is movable along vertical elements 54a' of a pallet tower 54.

By a vertical movement of the elevator 54b, the stackable pallets 55 carried by the elevator can be coupled to a handling pallet 56 to form a load unit in the pallet tower. The non-productive times can be reduced because two load units comprising empty handling pallets are available in the pallet tower 54. Such non-productive times occur when all empty handling pallets of the pallet tower 54 have been consumed and a load unit comprising full handling pallets must be removed before a load unit comprising empty handling pallets can be moved into the pallet tower 54 again.
