Title: Method and device for detecting oil spillage from oil tan or the like
Inventor: SHOJI AKIRA
IPC: G08B21/00
Filed: 1994-06-27
Abstract: PURPOSE:To detect oil spillage in an early state and to prevent erroneous information by using a detecting body which swells when oil penetrates into the body and detects oil spillage from the change of its electrical resistance as an oil spillage sensor and measuring the electrical resistance of the body at regular time intervals, and then, issuing an alarm when the difference between the resistance value of this time and that of the preceding time exceeds a threshold. CONSTITUTION:A webbing-like oil spillage sensor S composed a composite material of, for example, carbon black and silicon elastomer is set in a water passage (g) on the periphery of an oil tank and the detected resistance value of the sensor S is inputted to a detector (a) through a waterproof connection box (h). In the detector (a), the input signal is converted into a digital value at an A/D conversion circuit (c) after the signal is converted into a voltage by a resistance-to-voltage converting circuit (b) and the variation of the resistance value is compared with a threshold at a logic circuit (d). When the variation exceeds the threshold, an alarm is issued by actuating a buzzer (e) and LED. Since the detecting value of the sensor S changes when an abrupt temperature change occurs in a short time, in addition, a temperature sensor is additionally provided to stop the alarm when the temperature sensor detects an abrupt temperature change so as to prevent an erroneous alarm from being issued.

If SH >, the outlet of the vaporizer has superheat and indicates a dash of dryness. Therefore, it is possible to subtract a specified correction value a from the present opening of an electronic expansion valve 4 and determine a new opening. During heating the subcooling is calculated from temperature sensors 8 and 9 respectively. These calculated values are determined to see at which region they stay of these A, B, proper, C, and D. The specified correction values a and b are respectively added to the opening of the valve under the operation based on the result or correction values c and d are subtracted so that a new opening may be determined.
