Title: Loop connection control system
Inventor: OBARA KEIICHI
IPC: H04L12/42
Filed: 1983-04-30
Abstract: PURPOSE:To attain simply loopback by using a station not receiving a signal for a prescribed time as a control station of the loopback in a symmetrical decentralized type double loop transmission system. CONSTITUTION:Assume that stations C, D of a loop transmission system where stations A, B, C, D and E are connected in order are opened. Since a signal on an active loop is not received for a prescribed time in this case, the station D recognizes the station E as a loopback control station and transmits a loopback packet A to the station E. The station E relays the loopback packet to the station A and returns it to the station D. Then the station D recognizes that the stations D and E are connected. Similarly, the station E recognizes the connection of both the stations by the return of the loopback packet from the station A. Then, the above procedure is repeated. The station C discriminates that the own station is a loopback terminal station because no loopback packet is returned from the station D to perform the loopback. Further, the other stations release the loopback.

Title: Hermetic electrically driven compressor
Inventor: IIZUKA TATSUYUKI
IPC: F04B49/10
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal temperature rise of a hermetic electrically driven compressor and reduce possibility of leakage of combustible coolant by adopting an overload projector which succeeds an interruption state of an electric circuit in an abnormally temperature rise area, and its contact is not reset in a normal temperature state. SOLUTION: When temperature of a stator of an electrically driven element reaches an excessive temperature rise area due to dusts biten into a rotary shaft of a hermetic electrically driven compressor 1, a bimetal 5a of an overload protector 5 is reversed for opening a contact 5b. When the temperature of the stator falls to a resetting temperature of the bimetal 5a, the bimetal 5a is reversed for closing the contact 5b again. When continuous current carrying is performed in the bimetal 5a due to depositing of the contact 5b or the like and the temperature of the stator is in an abnormal temperature area, the contact 5c of the overload protector 5 is opened for stopping carrying current to the stator. Once the contact 5c is opened, it is not closed any longer. Abnormal temperature rise of the compressor is thus prevented.

Filed: 1980-06-05
Abstract: PURPOSE:To decide a logical value by means of a pitch of an output sound, by a method wherein a device is constituted such that a high and a low oscillating sound are outputted from a speaker in a manner to correspond to a logical voltage level at a point to be measured. CONSTITUTION:Two units of oscillating circuits 21 and 22 are mounted, and the oscillating circuits 21 and 22, both of which provide with 2 inverters, are of unstable multivibrators. Both of them oscillate audible frequency voltage and the oscillating frequencies are different from each other. For example, in case of the frequency of the oscillating circuit 21 is higher than that of the circuit 22, the application of a level voltage of a logic (H) to an input terminal outputting of a sound, having a high frequency, from a speaker 34. Conversely, when a level voltage of logic (L) is applied to the input terminal 1, a logic at an output terminal point of a second input potential decision circuit becomes (H), the output of the oscillating circuit 22 passes through gates 29 and 30, and as a result, a sound, having a low frequency, is outputted from the speaker 34. This constitution permits the decision of a logical value by means a pitch of an output sound.
