Title: Method and device for recording photon mode optical recording medium
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/0045
Filed: 1993-10-18
Abstract: PURPOSE:To provide the good reproducing signal by reducing the distortion of reproduced waveform generated by photon mode recording. CONSTITUTION:In the case of photon mode optical recording medium with the low optical density whose reflection rate is more than 0.3, the light is irradiated to a recording pulse-off section by the expansion of a spot when a recording pulse with duty 50% is used. A recording mark edge is expanded on a time axis and the distortion of reproduced waveform is generated. Because of the photon mode, the intensity of mark edge fluctuation is kept constant less than half of a spot diameter phi at the front and back end sections regardless of the recording pulse width. When the compensation shortening the pulse width with the time width tau is performed uniformly, the secondary distortion of the reproduced waveform can be reduced. The time width tau is higher than 0 and is phi/v (v is the relative speed laser spot of medium). By adjusting the value of capacitor C1 and resistor R1 of monomulti vibrator HC123, the time width taucan be uniformly set regardless of the recording signal pulse width and pulse intervals.

Abstract: PROBLEM TO BE SOLVED: To obtain the valve travel of an electronic expansion valve at the time of completion of a defrosting operation which corresponds to the actual situation of installation, by a method wherein the valve travel after completion of defrosting is corrected on the basis of learning from the electronic expansion valve at the time of completion of defrosting in the past. SOLUTION: In an air conditioner which has a refrigerant circuit equipped with a compressor 1, an outdoor heat exchanger 3, an electronic expansion valve 5 and an indoor heat exchanger 6 and wherein a defrosting operation for removing frost occurring on the outdoor heat exchanger 3 at the time of a heating operation is conducted by switching the direction of flow of a refrigerant in the circuit over to a reverse cycle, a corrective value Cd for correcting the valve travel of the electronic expansion valve 5 at the time of completion of a next defrosting operation is determined so that it may correspond to a change in the temperature of a discharged gas refrigerant at the time of completion of the defrosting operation and the valve travel of the electronic expansion valve 5 in the next time is set on the basis of the corrective value Cd.  Thereby the corrective vale Cd corresponding to the change in the temperature of the discharged gas refrigerant at the time of completion of the defrosting operation in the past is reflected on the valve travel of the electronic expansion valve at the time of completion of the defrosting operation in the next time.
