Title: Cmi decoding circuit
Inventor: FUKAGAWA TAKESHI
IPC: H04L25/49
Filed: 1984-11-19
Abstract: PURPOSE:To prevent increase in the hardware scale by using a clock obtained by a differentiation circuit and a counter to sample and hold the first half bit data of a CMI code signal in the 1st flip-flop and obtaining a signal subject to NRZ conversion from an EOR gate. CONSTITUTION:When an original data DT at the transmission side is 010, the original data DT becomes a CMI code signal SCM1 of 010001 according to the CMI coding rules. The 1st flip-flop 11 receiving the SCM1 as the D input uses the 1st clock CKi fed to the clock input CK to sample and hold the SCM1. The CMI code signal SCM1 subject to sample and hold is exclusively ORed with the SCM1 appearing at the next at an EOR gate 13, and the signal SMRZ of the NRZ code form is obtained at the output of the EOR gate 13. A decoded signal S'CM1 is obtained by applying sample and hold to the signal SMRZ at the 2nd flip-flop 12 synchronously with the 2nd clock CK2.

Abstract: PURPOSE:To eliminate the need for mutual supervision and to attain synchronization with high reliability by supplying a synchronizing clock from a master/sub master station having a master clock source of one loop local area network to other master/sub master station. CONSTITUTION:A master station C of a loop local area network LAN(A) supplies synchronizing clocks 1, 2 normally to a master station F and a sub master station G of a LAN(B).

Abstract: PURPOSE: To prevent the freezing, the bursting of a heat exchanger for warm water by providing a sensor for detecting the outdoor air temperature when the outdoor air temperature is a predetermined temperature or lower at the time of trially cooling of an installation construction and lowering the operating frequency of a compressor. CONSTITUTION: At the time of trially cooling an air conditioner in which an outdoor unit 1, indoor units 16A, 16B, 16C are coupled by tubes between the contained units, a controller 16 is operated in response to a signal from an outdoor air temperature sensor 14 to control the operating frequency of a compressor 6, thereby preventing the freezing, the bursting of a heat exchanger for warm water. When the outdoor air temperature is 21 deg.C or higher, there is no danger of freezing, bursting the exchanger for the warm water, and the compressor is operated at a rated frequency of 75Hz. When the outdoor air temperature is 21-5 deg.C, the outdoor air temperature is low and the evaporating temperature of the refrigerant becomes low, and hence it is considered to be dangerous, and the operating frequency of the compressor is linearly lowered to 69-26Hz.  When it is 5-0 deg.C, it is operated at the frequency of 25Hz. Further, when it is lower than 0 deg.C, it is dangerous, and hence it is so controlled as to refrain the trial operation.
