Inventor: ANZAI KAZUHIRO
IPC: F25D21/08
Filed: 1987-11-25
Abstract: PURPOSE: To reduce power consumption by setting a longer precool time for a higher operating rate of a compressor operated by an operating means prior to forced operation thereof thereby suppressing abnormal inner temperature rise at the time of defrost operation. CONSTITUTION: A counter 10 integrates the operating time of a compressor 1 and when it reaches a specified value, an auxiliary counter 11 starts counting synchronously. Subsequently, an operation control circuit 6 operates an operating rate Q and a longer precool time TP is set for a higher operating rate Q before being stored in a memory circuit 12. When the integrated operating time of the compressor reaches a set time, the circuit 6 reads out the precool time TP from the memory circuit 12 and starts operation of the compressor 1 forcibly. Operation is stopped upon elapsing the time TP and defrost operation of the cooler is started. According to the arrangement, inner temperature rise is suppressed at the time of defrost operation and precool operation is minimized.

Abstract: PURPOSE:To reduce DC application due to capcitance coupling without complicat ing a process and impairing an opening ratio, etc., and also to improve the DC application due to shortage in the write characteristic of a TFT by setting the signal amplitude of a data signal supplied to a data line to different value from each other in the term writing positive voltage to a pixel and in the term writing negative voltage. CONSTITUTION:A counter signal alpha imparted to counter electrodes is made a signal deviated by 7, 8 to the central value of the data signals with positive and negative both polarities, and respective different amplitudes from each other are imparted as DELTAD1 in a negative polarity frame, DELTAD2 in a positive polarity frame. A condition for suppressing the DC application due to pixel capacitance is that the counter signal potential alpha is set to a coincidence value when an ideal value alpha1 in the ON state of the counter signal potential alpha and the ideal value alpha2 in the OFF state coincide. In such a case, the DC application is suppressed when the condition of DELTAD1-DELTAD2=DELTAV1-DELTAV2 is satisfied. Where, DELTAV1, DELTAV2 are voltage drops shown in 9, 12.
