Title: Fin tube and method for enamelling same
Inventor: KANEDA BUNJI
IPC: F28F1/32
Filed: 1992-02-18
Abstract: PURPOSE:To improve resistance to acid and corrosion of an outer peripheral end part of the fin tube having an enamel coating layer formed on its surface. CONSTITUTION:In a tube 1 having fins 2 fixed to its outer periphery, the end part of the fin 2 has a shape free from acute angles, e.g. a rounded shape formed by rounding the outer peripheral end part of the fin 2. An enamel coating layer 3 is formed on the outer periphery of the fin 2. Since the outer peripheral end part of the fin 2 is rounded, upon application of enamel coat, the enamel coating layer 3 formed on the rounded part will not become thinner than on the other parts, consequently forming an even enamel coating layer 3. As a result, the outer peripheral end part of the fin 2 has an excellent resistance to acid and corrosion.

IPC: F25B37/00
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To improve the performance of an absorber by increasing the inflow amount of refrigerant vapor into an absorbing tube in a vertical type absorber. SOLUTION: An absorber prevents the deterioration of the inflow amount of refrigerant by mitigating the change of a flow passage sectional area upon the inflow of refrigerant vapor, introduced into the vertical type absorber, into an absorbing pipe. An embodiment is constituted of a substantially horizontally arranged partitioning plate 7E and a plurality of heat transfer tubes 7A, whose upper end part is projected to the upper part of the partitioning plate 7E and which are arranged while retaining whose axial lines upright substantially. Refrigerant vapor, which flows into the heat transfer tubes 7A from the upper end part of the same, is absorbed into absorbing solution 50, reserved on the partitioning plate 7E and flows down along the inner peripheral walls of the heat transfer tubes through solution dripping ports 7D bored on the wall surface of the heat transfer tubes 7A.  In this case, the inner diameter of the heat transfer tube 7A, within a range from the upper end of the same tube 7A to a predetermined position below the solution dripping port 7D, is expanded so as to be tapered so that the inner diameter is increased from the original inner diameter d1 of the heat transfer tube to the maximum inner diameter d2 (=1.05d1-1.2d1) and is reduced to the inner diameter d1 at a predetermined position as the position is lowered.

Title: Calculating method for vehicle speed
Inventor: MOROSAWA AKIHIRO
IPC: G01R23/10
Filed: 1985-02-19
Abstract: PURPOSE:To average synchronization and to obtain a stable vehicle speed by measuring a pulse output time corresponding to a vehicle speed and dividing the measured value by the number of times of pulse output to find out the synchronization of pulse signals. CONSTITUTION:When pulse signals P are supplied from a vehicle speed sensor 3 to a controller 5 during the advancing of a vehicle and the number of input pulses P reaches a sampling number (n), the contents of a period area A2 of a work memory 6 are transferred to an area A3, and the contents stored in an area A1 are transferred to the area A2. Then, the contents stored in a counter area storing the counted value of pulses TP from a timer 4 are divided by the sampling number (n). Consequently, the average period per pulse of the signal P can be found out. Thus, the period variation due to factors other than speed change can be suppressed.
