摘要： A liquid crystal panel brightness controller notifies a backlight controller that an illuminance of ambient light is equal to or less than a threshold value. Upon notification, the backlight controller causes invisible light emitted, for example. The invisible light passes through a liquid crystal panel and is reflected by an imaging target and is received by photosensors. Accordingly, the decrease in the amount of the visible light received by photosensors is compensated. As a result, an image with a high S/N ratio is obtained.

摘要： An optical encoder comprising a light-receiving part having photodiodes equal in number to the common multiplier of a number of slits facing the light-receiving part and a number of movement information signals. Output terminals of the photodiodes are connected so that the movement information signals are respectively obtained by adding output signals of the plurality of photodiodes out of the photodiodes equal in number to the common multiplier. The twelve photodiodes are balancedly arranged corresponding to three slits and a light-receiving area of each photodiode is made smaller by subdiving each photodiode. The optical encoder suppress difference, distortion and variance of the movement information signals or the like obtained from the light-receiving part with the result that accurate movement information is obtained.

摘要： An air conditioning system has a compressor that compresses a refrigerant and is capable of changing a flow rate of the refrigerant to be discharged, and an evaporator for evaporating the refrigerant to cool air. The evaporator is arranged in a casing that forms a passage to direct air into a vehicle cabin. When the refrigerant flow rate remains smaller than or equal to a predetermined flow rate substantially over a first predetermined time from when the refrigerant discharge flow rate falls to or below the predetermined flow rate, the compressor is operated so that the refrigerant discharge flow rate becomes greater than the predetermined flow rate at least over a second predetermined time that is shorter than the first predetermined time. In intermittent operation mode, the discharge flow rate is made greater than the predetermined flow rate for only a second elapsed predetermined time at every elapsed time.
