Abstract: An electronic equipment such as a CPU body of a computer system includes a circuit board section, an abnormal temperature detecting section, a determining section, a refrigerant cooling system, and an alarm unit. The circuit board section for effecting preset signal processings includes a printed circuit board on which at least one PTC (Positive Temperature Coefficient) thermistor built-in type integrated circuit device including a package, an integrated circuit chip disposed in the package, a PTC thermistor disposed between the package and the integrated circuit chip, and an electrical deriving member disposed in the package, for transferring a signal with respect to the integrated circuit chip and PTC thermistor, and electronic elements are mounted. The abnormal temperature detecting section outputs an abnormal temperature signal when an output of the PTC thermistor has exceeded a preset value.

Abstract: A housing structure for housing a plurality of electric components includes a skeleton frame, an air intake section, an air exhaust section, an air passage section, a plurality of electric component housing bodies, and a confluence preventing member. The skeleton frame has a polyhedron space defined therein. The air intake port introduces air into the polyhedron space in the skeleton frame from the exterior thereof. The air exhaust section exhausts air from the polyhedron space in the skeleton frame to the exterior thereof. The air passage section is formed in the polyhedron space in the skeleton frame. The plurality of electric component housing bodies receive a plurality of electric components in a two- or more-storied configuration. The confluence preventing member prevents air exhausted from a lower side electric component housing body and air introduced into an upper side electric component housing body from being combined together.

Abstract: A housing unit for containing electronic equipment consists of a plurality of housings which are connectable one to another. Each independent housing has respective first intake and exhaust ports formed in opposite sidewalls as well as respective second intake and exhaust ports formed in the front and rear walls respectively. An air flow passage is formed between the first intake and first exhaust ports through the chassis of the equipment contained in the housing when one housing is used as a stand alone unit. The individual housings are so constructed to be connectable in a way that air flow passages are conveniently formed in each housing with a common partition wall between the passages.

Abstract: A quake-proof chassis for accommodating a display monitor comprises a main frame, a bottom reinforcement member, a cathode ray tube support frame and a rear panel member. A quake-proof chassis for accommodating power units and/or control units comprises left and right side panels having outwardly bent front end portions and inwardly bent upper and lower flanges, top and bottom panels having outwardly bent flanges provided along all the sides, and front and rear panels having inwardly bent upper and lower flanges.
