Title: Synchronizing circuit
Inventor: UNO TAKASHI
IPC: H04L7/02
Filed: 1985-01-30
Abstract: PURPOSE:To prevent an intermediate level from penetrating an internal circuit by constituting the first bistable circuit so that the output at the balance point of this circuit has two kinds of potential different from each other and setting an input logical threshold of the second bistable circuit so that this threshold is in the middle between these two kinds of potential. CONSTITUTION:The first bistable circuit 11 is so constituted that potentials V1 and V2 at points P1 and P2 are potentials Vm1 and Vm2 different from each other at a balance point 13. The input logical threshold of the second bistable circuit 12 is so set that it is in the middle between said potentials Vm1 and Vm2. By this constitution, the malfunction that the intermediate level penetrates the internal circuit is prevented because the state of the second bistable circuit 12 is not changed when the first bistable circuit 11 which receives an asynchronous input does not reach the stable state and is stopped at the balance point. Thus, the asynchronous input is synchronized stably.

Title: Heat exchanger for thermal decomposition furnace
Inventor: MARUTA TAMIO
IPC: C07C11/02
Filed: 1991-02-07
Abstract: PURPOSE:To enable sensitive heat held by generated gas to be recovered under a high efficiency by a method wherein a plurality of cooling pipes are branched and connected in parallel with a single cooling pipe and two cooling portions having generated gas outlets of the plurality of cooling pipes are disposed within the same shell having heat exchanging medium flowed therein. CONSTITUTION:Generated gas of high temperature produced from a thermal cracking furnace for hydro-carbon keeps its high speed flow at a part of a primary cooling pipe 31 and is cooled to a temperature less than a freezing temperature of secondary reaction. The gas is changed into a low speed flow at a part of a branched secondary cooling pipe 32 and at the same time a cooling area is increased. Due to this fact, an entire length of the cooling device is shortened more than that of the double-piped structure in which the prior art primary cooling device and the secondary cooling device are integrally formed together and so an intermediate communication pipe between the high temperature cooling pipe connected to a reaction pipe of the thermal cracking furnace and the prior art primary and secondary cooling devices can be eliminated. Accordingly, a pressure loss caused by a pipe resistance of the produced gas can be substantially reduced.

Title: Pressure sensor mounting structure for air bubble generating bath tub
Inventor: HARAGA HISATO
IPC: A47K3/10
Filed: 1990-01-28
Abstract: PURPOSE:To high-precisely detect a level in a bath tub body communicated to a bath tub body by mounting a pressure sensor, used for general detection of a level, detection of a level for prevention of racing of a circulating pump, and detection of abnormal operation, on the bath hot water suction side of the circulating pump. CONSTITUTION:A pressure inspecting hole Sph is formed in the wall body of a bath hot water suction passage 32a of a circulating pump P, and a closed container Sp11 is located between the pressure inspecting hole Sph and a pressure sensor Sp. A pressure transmission passage Sp0 is communicated to the upper end part of the closed container Sp11, and the pressure receiving part of the pressure sensor Sp to the lower end part thereof. The closed container Sp11 is filled with pressure oil transmission oil Sp12, e.g. phlorocarbon, having specific gravity higher than that of water and insoluble in water. The pressure transmission oil Sp12 is positioned at the lower inner part of the closed container Sp11 and bath hot water in a bath hot water suction passage 32a at the upper inner part. A bath hot water pressure in the bath hot water suction passage 32a is transmitted indirectly to the pressure sensor Sp through the pressure transmission oil Sp12. This constitution prevents lowering of sensitivity due to corrosion of the pressure sensor Sp and adhesion of bath tub scale, and holds high precision for a long period.
