Videocassette recorder
The videocassette recorder, VCR, or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette, and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as timeshifting. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, until the VCR was superseded by the DVD player and PVR, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings.
Most domestic VCRs are equipped with a television broadcast receiver (tuner) for TV reception, and a programmable clock (timer) for unattended recording of a television channel from a start time to an end time specified by the user. These features began as simple mechanical counter-based single-event timers, but were later replaced by more flexible multiple-event digital clock timers. In later models the multiple timer events could be programmed through a menu interface displayed on the playback TV screen ("on-screen display" or OSD). This feature allowed several programs to be recorded at different times without further user intervention, and became a major selling point.
Vapor-compression refrigeration
Vapor-compression refrigeration or Vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air-conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for chilled or frozen storage of foods and meats, refrigerated trucks and railroad cars, and a host of other commercial and industrial services. Oil refineries, petrochemical and chemical processing plants, and natural gas processing plants are among the many types of industrial plants that often utilize large vapor-compression refrigeration systems.
Refrigeration may be defined as lowering the temperature of an enclosed space by removing heat from that space and transferring it elsewhere. A device that performs this function may also be called an air conditioner, refrigerator, air source heat pump, geothermal heat pump or chiller (heat pump).

Something's talking
New sensations, feelings
Looking for dreams
I can remind you
I can remember
I can live daydream
There's my place
From a distant space
A star is coming
New procession calling
Trying to thrill me
I can't remind you
I can't remember
I can't remain here
On your dream
Man you see I fly tonight
You can really meet sunrise
If you get the friends today
You can really flap your hands
I began to know you now
When your eyes are watching me
You don't have to lose yourself
There's a new world coming now
From a distant space
A star is coming
New procession calling
Trying to thrill me
I can't remind you
I can't remember
I can't remain here
On your dream
Man you see I fly tonight
You can really meet sunrise
If you get the friends today
You can really flap your hands
I began to know you now
When your eyes are watching me
You don't have to lose yourself

I began to know you now
When your eyes are watching me
