Title: Two-way waveform clamper
Inventor: YOKOTA MASAFUMI
IPC: G06K7/10
Filed: 1979-01-10
Abstract: PURPOSE: To make it possible to clamp definitely the maximum and minimum of an analog signal to set values respectively by inputting the output of an operational amplifier to error amplifiers differing in set reference value and then by feeding their outputs back to the input side of the operational amplifier.  
     CONSTITUTION: Since diode 14 is biased forward to +V cc  in a stationary state, the output of operational amplifier 3 is fed back to its input side by way of error amplifier 6. As a result, the waveform of output signal (b) is clamped to a value equal to reference potential (c). Although analog signal (a) from terminal 1 rises gradually, diodes 14 and 15 are both OFF until variation in amplitude becomes constant, and output (b) varies with the gain of operational amplifier 3. Once the amplitude exceeds certain width and the amplitude of output (b) surpasses reference voltage (d), diodes conduct to feed the output of error amplifier 7 back to the input side of amplifier 3 and from the point in time until the point when the waveform of signal (a) reaches its peak, output (b) is clamped to the same potential as reference potential (d). Further, when signal (a) falls from its maximum, output (b) is clamped to reference potential (c).

Filed: 1995-01-09
Abstract: PURPOSE: To accurately receive a signal from a transmission line at low cost and with simple constitution even if such a fault that the transmission line is disconnected occurs. CONSTITUTION: If a 1st transmission line 10 is disconnected, a potential Va which is converted by a 1st potential converting circuit 21 connected to this transmission line is so converted that (reference potential Vc) < (potential Va) > (potential Vb at passive time). If a disconnection fault occurs to a 2nd transmission line 11, a potential Vb which is converted by a 2nd potential converting circuit 22 connected to this transmission line is so converted that (reference potential Vd) > (potential Vb) < (potential Va at passive time). One of comparators 23-25, therefore, outputs a normal signal at all times.

An outdoor heat exchanger 6 functions as a condenser at the time of air cooling and as an evaporator as the time of air heating, when the heat pump is operated. A cooling medium heater 7 functions as an evaporator at the time of air heating  when the open air temperature is low. An open valve 8 is opened to let the cooling  medium flow in case the cooling medium heater is used to function as the evaporator at the time of air heating when the open air has a low temperature.
