Title: Damper body and damper device for air conditioning
Inventor: KOBAYASHI MAMORU
IPC: F24F13/15
Filed: 1990-02-22
Abstract: PURPOSE:To automatically vary the opening of an outlet port and enable comfortable air conditioning by utilizing the transformation of shape memory alloys as the operational force of a damper for air conditioning. CONSTITUTION:In a damper body A, air passing through damper plates 1 flows so as to always contact with shape memory alloys 6 and, when a passing air temperature reaches the critical temperature of the shape memory alloys 6, the damper plates 1 pivot around pivot axes 2 and turn in the direction of closing an outlet port. In this case, the two damper plates 1, 1 are opposed to each other and pivot almost simultaneously in a direction opposite each other. Therefore, the outlet port is quickly narrowed, and air is converted into the state of a nozzle-ejected air stream having directional characteristics, and the air stream effectively flows to places where an ordinary air current does not reach. For example, a damper body, which is used for discharging cold/hot air from a floor-plane, is so designed that damper plates are pivoted in the direction of closing an outlet port when cold air flows and that the same are pivoted in the direction of opening the outlet port when hot air flows.

Filed: 1986-02-24
Abstract: PURPOSE:To improve the accuracy and efficiency of the color convergence adjustment, by correcting automatically the convergence in the negative feedback to unify the central position of phosphor dot group, and correcting and storing the result in a PROM for digital convergence. CONSTITUTION:Only R spots in a cathode-ray tube are displayed at the center of the display screen, and an image processor 2 computes the central position from the positions of phosphor dots in the spot to be observed. In the same manner, the image processor 2 computes the central position of the phosphor G dot group when the CRT displays only G. The distance of the both central positions of R and G, that is, the color misconvergence, is computed. When the color misconvergence is out of the standard value, the image processor 2 computes the condition to correct the beam convergences of R and G, and the RAM 6 is renewed through a system control 3 and a memory control 5. Furthermore, the computing and correcting of the misconvergence between G and B are also carried out in the same manner.

Abstract: PURPOSE:To remarkably enhance electric characteristic and manufacture an insulated electric wire without any fray generated in a cut portion by winding a synthetic resin insulating tape around a conductor desired times in coexistence of a soluble solvent, and tightly bonding insulating tapes to each other so as to form an insulating layer. CONSTITUTION:While a straight conductor 1 of, for example, 2.0X10.0mm is being traveled at a predetermined speed, an Aramid paper tape 2 having a given thickness is wound around the conductor, and then, the conductor is passed through a solvent coating device 3 full of dimethylformamide. The tape is coated with dimethylformamide to be fitted to dimethylformamide, before being pressed by a heating roll 4 with application of heat so that a solvent contained in the Aramide paper tape is evaporated and dried, and consequently, the tapes are bonded to each other, thus obtaining an insulated electric wire. Therefore, an electric property can be remarkably improved, and furthermore, a connecting operation can be facilitated without any fray generated in a cut portion.
