An environmental apparatus control system assures a consistent temperature control for realizing a comfortable residential environment based upon demands from the residents, yet in an energy-saving manner. The system includes an apparatus for controlling a residential space, and an initializer which provides an initial target value for control of the residential space at the start of operating the system. Comfortableness demands from residents are analyzed in order modify the initial target value to a working target value. The initial target value is shifted in a direction of saving the energy such that the working target value can always approach from and settle on the energy-saving side as the demands from the residents are analyzed. The working target values within a past time period are weighted to give a corrected target value which replaces the initial target value for the start of next operation cycle of the system.

A disk cassette arrangement which includes a double sided disk is arranged to be used in both dual and single head disk drive units. The cassette case is comprised of upper and lower halves or shells which are formed so that a reinforcing rib is defined when they are coupled together. A guide slot is formed in the rib. The cassette features a shutter which has a U-shaped cross-section and which is slidably disposed on the leading edge of the cassette case. A projection which extends from the inboard edge of the shutter has a barbed like arrangement which can be inserted through a tapered section of the guide slot.

A tape cassette comprises a cassette housing including an upper section and a lower section. The upper section has a top wall including an opaque portion and a transparent window plate, and the lower section has a bottom wall formed with a pair of hub-receiving apertures therein. The top and bottom walls lie substantially in parallel spaced-apart planes. A pair of tape reels are mounted within the housing, each of the tape reels being formed with a hub and having an axis extending in a direction substantially normal to the planes of the top and bottom walls. The hubs are respectively rotatably received within the hub-receiving apertures. A rib is formed on the top wall and projects therefrom towards the tape reels. Each of the tape reels is movable axially between a lower position limited by engagement with the bottom wall and an upper position limited by engagement with the rib. The rib is spaced apart from the bottom wall a distance sufficient to enable axial movement of each of the tape reels away from the bottom wall in order to facilitate rotation of the tape reels but insufficient to enable withdrawal of the hubs from the respective hub-receiving apertures. The upper section of the cassette is formed by a method employing a mold having stationary and movable cores.
