Title: Current limiter device
Inventor: TSURUNAGA KAZUYUKI
IPC: H02H9/02
Filed: 1989-05-22
Abstract: PURPOSE:To promptly remove a thermal fault due to an overcurrent so as to suppress vaporization of a cooling medium by connecting the first superconducting coil in series and the second superconducting coil in parallel to a switching element. CONSTITUTION:At the time of generating an overcurrent, a flow of the current in a trigger coil 2a of small critical current value is suppressed. A switching element 2h is opened, a circuit of the trigger coil 2a is cut off and an electric current is supplied to a load 3. Since opening action of the switching element 2h is performed simultaneously with the reactor action of a current limiting coil 2b, the switching element, while it is surely actuated, operates at a high speed of action with out a delay. In this way, generation of a thermal fault due to the overcurrent can be promptly removed, and vaporization of a cooling medium such as helium can be effectively suppressed.

Title: Control device for vehicle air-conditioner
Inventor: DOI KAZUYUKI
IPC: B60H1/32
Filed: 1984-06-21
Abstract: PURPOSE:To reduce variations in the temperature of blow-out air and to hold the temperature of air in the vehicle compartment in a stable condition, by adjusting the medium discharge capacity of a compressor in accordance with the difference between a signal indicating an air temperature difference between the upstream and downstream sides of a medium evaporator, and a signal indicating a thermal load in the passenger's compartment. CONSTITUTION:The thermal load of the passenger's compartment of a vehicle and a present cooling capacity which is obtained from a temperature difference between the upstream and downstream sides of an evaporator, are compared with each other by comparator circuits 41, 42, and the cooling medium discharge capacity of a compressor 50 is adjusted in accordance with the result of comparison. That is, when the temperature difference between the upstream and downstream sides of the evaporator may correspond to the thermal load of the passenger's compartment, an electromagnetic clutch 51 is deenergized to isolate the compressor 50 from its power source while when the temperature difference is between the upper and lower limits of the thermal load, the clutch 51 is energized and therefore an electromagnetic device 25 is also energized to operate the compressor 51 as its one-half capacity. Further, when the temperature difference is below the lower limit of the thermal load, the electromagnetic device 52 is deenergized so that the compressor 50 is operated at its full capacity. With this arrangement the cooling capacity may be controlled in three stages, and therefore, the heat gain of supply air may correspond to the thermal load, thereby it is possible to reduce variations in the temperature of blow-out air.

Title: Longest linear code series generating circuit
Inventor: TAKAKU YOSHINORI
IPC: G01S7/292
Filed: 1994-06-13
Abstract: PURPOSE:To enhance the secrecy by outputting an initial value, corresponding to the length of M code (longest linear code series), arbitrarily from an M code initial value generating circuit and varying the phase modulation pattern of a transmission wave thereby spreading the transmission wave over a wider band. CONSTITUTION:A transmission timing generating section 5 receives a signal from a counter 4 and generates a gate corresponding to the transmission pulse width. An code length data of M code is fed through a bus transceiver 1 to an M code coefficient latch 6 thence to an M code generating section 7. Every time when an M code modification signal is received, an M code initial value generating section 9 delivers the initial value of M code, corresponding to the code length, arbitrarily to an M code generating section 7. Since the phase modulation pattern of transmission wave is varied as compared with the case where the initial value is constant, the spectral pattern of transmission wave is varied and the secrecy is enhanced.
