Title: Operation controller of air conditioning apparatus
Inventor: YAMAMOTO MASAKI
IPC: F25B13/00
Filed: 1991-11-26
Abstract: PURPOSE:To avoid stopping in the operation that is caused by a sudden change in the state of the coolant in the abnormality elimination control by means of a change in the air flow rate of an outdoor fan of an air conditioning apparatus. CONSTITUTION:When the instruction of operation by small air flow rate is outputted at night, etc., by a signal output means 12, the air flow rate of an outdoor fan 3a is reduced by an air flow rate reducing means 51A. At the same time the operational frequency of a compressor 1 is limited to below the upper limit value by a capability limiting means 52. With this arrangement a high pressure cut in the room cooling operation and the low pressure cut in the space heating operation are avoided. And, if, in the room cooling operation, the high pressure is below the lower limit value in the high air flow rate operation of the outdoor fan 3a, the air flow rate of the fan is changed over to a low air flow rate and, at the same time, the operational capacity of the compressor 1 is reduced. Further, if the high pressure goes over the upper limit value in the low air flow rate operation of the outdoor fan 3a, the air flow rate of the fan 3a is changed over to a high air flow rate and, at the same time, the operational capacity of the compressor 1 is increased. With this arrangement a change in the state of the coolant that accompanies a change in the fan air flow rate is restrained and stopping of the operation, etc., are avoided.

Title: Temp. control method for vaporizer of liquid fuel combustion apparatus
Inventor: MARUYAMA MITSUTAKA
IPC: F23N5/14
Filed: 1986-12-26
Abstract: PURPOSE:To make it possible to carry out stable blue flame combustion at all times in making the width of temp. change in a vaporizer small by a method wherein a temp. sensor detects the temp. of the vaporizer and also specified current-carrying is applied to an electric heater while the vaporizer continues vaporization. CONSTITUTION:When the temp. of a vaporizer 2 detected by a temp. sensor 6 ascendes gradually from the lower limit peak Q' and exceeds T (low), a control circuit detects that the temp. ascends with time and commands to stop the current carried to an electric heater 1. Though current-carrying is stopped, the temp. continues to ascend by the remaining heat of the vaporizer 2 and in due time, the temp. starts to descend after indicating a peak Q. However, as this peak is situated at a higher location than T (high), current-carrying to the heater 1 is not resumed until the temp. exceeds T (high) and descends. Thereby, the influences of over-shooting and undershooting are offset each other by the width between T (high) and T (low) in comparison with ON and OFF operation of the heater 1 with the borders of a fixed and constant temp. T0.

Title: Acceleration detecting device
Inventor: YAMADA TOSHITAKA
IPC: G01P15/08
Filed: 1987-12-11
Abstract: PURPOSE:To securely detect acceleration by setting the operation reference point of an amplifying means to an operation point where a DC drift is removed by a reference operation point correcting means. CONSTITUTION:Resistances 111 and 112 made of semiconductors are so connected together with resistances 121 and 122 as to constitute a bridge circuit. The output signal of the bridge circuit is supplied to a differential amplifier 13, which outputs a detection signal corresponding to the acceleration. The output signal of the amplifier 13 is amplified by an output amplifier 14 to amplify all frequency components including the drift, and led out as an output. Here, the output of the amplifier 14 cancels an output error due to the DC drift by the feedback system of an operation point correcting circuit 15 at the stop time of an automobile wherein the acceleration need not be measured. The output signal of the amplifier 14 is therefore corrected into an accurate signal accurately corresponding to the acceleration operating on the automobile body.
