Title: Heat exchanger for air conditioner
Inventor: AKAMATSU YUKIHIKO
IPC: F24F13/30
Filed: 1994-09-26
Abstract: PURPOSE: To prevent scattering of waterdrops from a discharge port of conditioned air by spacing the lowermost-end pipe nearest to the discharge port side from a frame body sufficieintly and also by forming louver-cut pieces in a fin. CONSTITUTION: A space H between the lowermost-end pipe 2 nearest to the side of a discharge port of conditioned air and a lower frame 31 of a frame body 3 is made 2cm or larger, while louver-cut pieces 11 to be dams of waterdrops are formed in longitudinal directions at a plurality of places in a fin 1 on the leeward side of the pipe 2 in the second line from the pipe 2 in the nearest line to the discharge port side. Even when dew water dropping on the lower frame 31 is driven toward the outlet side under an air pressure, therefore, the sufficient space H between the lowermost-end pipe 2 nearest to the discharge port side and the lower frame 31 prevents the water from being gathered and waterdrops getting over the pipe 2 in the second line from the pipe 2 in the nearest line to the outlet side are caught by the louver-cut pieces 11 of the fin 1.  Thereby scattering of the waterdrops from the discharge port can be prevented even when the velocity of air being processed is increased.

IPC: G01P21/00
Filed: 1992-09-28
Abstract: PURPOSE:To enable an error to be detected, regarding acceleration detection signals outputted within a normal signal output range, by differentiating an acceleration detection signal, and making a comparison between the differentiated signal and the predetermined threshold value. CONSTITUTION:A pair of diagonal nodes of piezoresistance elements 8a to 8d having a bridge connection are connected to a power supply and driven on direct current. The elements 8a to 8d, when exposed to acceleration, generate strain, and thus a potential difference appears between other diagonal nodes. A microcomputer 40 performs the execution of various types of control, using the potential difference, and makes judgement about the occurrence of an error in an acceleration sensor 10. That is, a detected signal is differentiated and a low-frequency component is eliminated from the signal. Also, the sensor 10 is judged in terms of whether a signal showing such a sharp change as exceeding a threshold value is thereby detected, via comparison between the differentiated signal and the predetermined threshold value. When a sharp change in acceleration is repeatedly detected, the sensor 10 is judged to be generating a certain error.
