A slip-out preventive unit of a supply exhaust pipe assembly with a supply exhaust pipe forming a faucet at one end and forming an insertion port at the other end. The faucet having a cut window to allow the lock portion of a lock member to pass through the faucet to engage a circumferential groove of the insertion port. A slip-out prevention unit of which the lock member is a component, to guide and constrain the lock member to engage the circumferential groove, resulting in the holding of the insertion port within the faucet preventing unwanted separation after connection of the assembly. A slide guide allows movement of the lock member in an axial direction of the faucet where the tip of the lock member may be constrained from radial movement of the engagement portion of the lock member by a locking bag wall upon an attempt to separate the insert portion from the faucet. The insert portion being insertable and removable of the faucet when the lock member is in a withdrawn position relative to the locking bag wall, thus allowing the engagement portion of the lock member to be radially displaced by the end of the insertion port or the slope of the circumferential groove of the insert port as it is inserted or removed from the faucet respectively. The locking member being moved to its withdrawn position either by direct force acting upon the lock member from the insertion port as it is inserted into the faucet for connection of the unit, or by an external operator applied force against the lock member prior to removal of the insertion port from the faucet.

An apparatus 9 for diagnosing failures in the combustion system to be installed in the regenerator of an absorption chiller is adapted to automatically prepare quantitative diagnosis data from a plurality of items of measurement data. The apparatus comprises an abnormality degree calculating circuit 2 for calculating degrees of abnormality serving as indexes for discriminating failures, from different items of data obtained by a combustion system control unit 1, a binary conversion circuit 4 for converting the abnormality degrees obtained from the circuit 2 to binary data representing 'normal' or 'abnormal,' a condition judging circuit 5 for discriminating types of states of failures from the binary data by driving a diagnosis knowledge base 7, and a diagnosis data calculating circuit 6 for calculating diagnosis data from the abnormality degrees and types of failure states by driving the base 7.

A radio communication system comprises plural hand held terminals and a base station communicating with each of the hand held terminals by a two-way radio data transmission. The hand held terminal is set with a system ID number by a proper signal representing the system ID number sent from the base station through a radio data transmission.
