Filed: 1990-08-07
Abstract: PURPOSE:To allow a variable delay circuit to change delay time while the circuit secures a sufficient logical amplitude as a variable delay circuit by providing a buffer circuit which functions as a logical gate and exclusive OR circuit which controls the delay time. CONSTITUTION:When a delay time control signal inputted to an exclusive OR circuit 2 is low in level, the output of the circuit 2 becomes the same as that of a buffer circuit l and the voltage across both ends of capacitor 3 always fluctuates in the same phase, with input signals to the circuit l being outputted as they are. On the other hand, when the delay time control signal inputted to the circuit 2 is high in level, the output of the circuit 2 becomes opposite in phase to input signals. Therefore, the voltage across both ends of the capacitor 3 always fluctuates in the opposite phase and acts on the output of the buffer circuit 1 as a capacitance. In other words, the output signal of the circuit l is outputted after it is delayed in accordance with the charging time of the capacitor 3.

Title: Piping structure and piping panel for heating building
Inventor: SHIDA HIROSHI
IPC: F24D3/16
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent the corrosion of a metal plate, and to facilitate the changing work of the metal plate or a heating medium pipe by having a specific contact structure, in which the contact position of the metal plate for heat dispersion to the outer periphery of the heating medium pipe is transferred from the bottom part to the upper part of the heating medium pipe. SOLUTION: A metal plate for heat dispersion 6 forms an arc-shaped metal contact piece 4 integrally by folding back a pair of leg pieces 5, which are formed by being folded obliquely downward toward the outer periphery surface of a heating medium pipe 1, from its lower end. Moreover, the leg pieces 5 forms the arc-shaped metal contact piece 4 out of the metal plate 6 for heat dispersion by covering the internal wall of a recessed groove 3 of a heat insulating plate material 2 to be folded and suspended, and by being folded at the position where the clearance between the internal wall surface and the outer periphery of the heating medium pipe decreases. Therefore, the condensed water which gathers in the recessed groove of the heat insulating plate material does not contact the metal plate for heat dispersion, so that corrosion does not occur.  Thereby, the heat transfer from the heating medium pipe is maintained, and also the decline in the heat efficiency is prevented.
