Title: Picture processor
Inventor: KUROKAWA KUNIAKI
IPC: H04N5/202
Filed: 1990-07-06
Abstract: PURPOSE:To reduce conversion error by converting a digital signal with an enlarged converting characteristic and converting the signal to an analog signal reduced at magnification corresponding to the enlarging rate of the converting characteristic when an input luminance level is low. CONSTITUTION:According to gamma curves 60 and 62, a system control circuit 42 converts a picture signal and supplies it to an amplitude modulation circuit 50 and simultaneously, a signal is supplied to a switching circuit 48 so as to show whether the luminance level is lower than a prescribed value 11 or not. The amplitude modulation circuit 50 forms the amplitude modulated wave data of 8 bits, outputs the data to a D/A converter 32 and simultaneously supplies a switch control signal to the switching circuit 48. When the luminance level is lower than the prescribed value I1, switching circuits 44 and 46 select a 1/4 reference voltage generating circuit 46 and when the level exceeds the value I1, a reference voltage generating circuit 44 is selected. Then, the picture data is supplied to the D/A converter 32 as a reference voltage. Namely, the D/A converter 32 executes D/A conversion over the 1/4 voltage range in comparison with a normal case in respect to the amplitude modulated wave based on the gamma curve 62.

Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To receive high-quality signals at both a base station and every terminal equipment by applying orthogonal codes as the spreading codes of transmitted signals to respective incoming and outgoing lines. SOLUTION: When the initial synchronism acquisition of spreading codes is completed in a search mode, a synchronism acquisition circuit 214 outputs search phase information SP-i. On the other hand, a discrimination circuit 213 outputs phase difference information PD-i by performing the comparing operation of received phases in parallel with the inverse spreading processing of received signals Rx in a phase control mode. At the time of change from the search mode to the phase control mode at the base station, under phase jump control and transmission phase control to be performed in the phase control mode at every terminal equipment, the phases of received signals from respective pieces of terminal equipment can be equalized at the base station.  Therefore, while effectively utilizing the characteristics of orthogonal codes, transmitted signals Tx-i from respective terminals can be prevented from mutual interference.

Abstract: PURPOSE:To allow the refrigerant to surely exchange heat with the air by operating multiple fans at the time of a high-capacity operation of a compressor to set the air volume at a high level. CONSTITUTION:When there is a large difference between the set temperature and the room temperature, coils 26a, 26b are electrified, contact points of variable relays 19a, 19b are thrown into a forced terminal 27, and upper and lower fans 15a, 15b are turned at a high speed. At the same time, power at a high frequency is supplied from a frequency control device 32 to the compressor 5 to cause the compressor 5 to discharge a large amount of refrigerant. At this time, the room air drawn from an air intake grill 16 is heated and blown out of an upper outlet 17a and a lower outlet 17b to allow the room temperature to quickly approach the set temperature. When the difference between the room temperature and the set temperature became small, the operation of the upper fan 15a is stopped, and the lower fan 15b is operated at a low speed. Further, the amount of refrigerant discharged from the compressor 5 is reduced, and the room air that was heated by the room unit heat exchanger 14 is blown only out of the lower outlet 17b by the rotation of the lower fan 15b.
