Abstract: PURPOSE:To improve the waveform o an output signal by constituting a delay circuit having a preshoot characteristic and using an absolute value of an input signal and a delay signal to switch the signal corresponding to the result of comparison between a prescribed difference and a threshold level. CONSTITUTION:A signal inputted to an input terminal 1 is retarded by a delay circuit by a time D and retarded by a time D1 at a preshoot delay circuit 31 and a signal retarded sequentially is inputted to input terminals a, b, c of a changeover switch 13. Subtractors 4, 5 calculate the amplitude difference of the signals inputted to terminals a, b and b, c and absolute value circuits 6, 7 output the result A, B of subtraction. Then a subtractor 9 obtains the difference between the values A, B and an absolute value circuit 10 outputs the absolute value C.

Title: Controlling device of refrigeration cycle
Inventor: UENO YUKIYASU
IPC: F25B1/00
Filed: 1990-10-12
Abstract: PURPOSE:To prevent an uncomfortable rise of a blowoff temperature by a method wherein a value of a second element is changed over and a drive of the closing side of a variable-opening expansion valve is suppressed, when it is determined that a cooling capacity lowers beyond a prescribed range, on the basis of the condition of operation of a refrigeration cycle. CONSTITUTION:Bubbles tend to be generated in a refrigerant in the course of a rapid drop of a boiling point due to the heat capacity of a piping or others. When the bubbles are generated, an expansion valve 7 can no longer make a refrigerant in the quantity corresponding to the opening thereof at this time flow, the degree of an overheat in an evaporator 9 increases and a blowoff temperature is made to rise. In the case when such a condition of operation as the above is brought force, a value of a second element is changed over so that a drive of the closing side of the valve is suppressed. By suppressing a quick drive control on the closing side of the expansion valve 7 at the time of lowering of a cooling capacity when the bubbles tend to be generated, in this way, a flow rate of the refrigerant onto the compressor 1 side is secured, a sharp drop of a discharge pressure of the compressor 1 can be prevented and the generation of the bubbles is suppressed. Thereby a long-time rise of the degree of an overheat is prevented and an uncomfortable rise of a blowoff temperature can be prevented.

Title: Radiation measuring instrument
Inventor: KAWAMOTO TETSUYA
IPC: G01T1/24
Filed: 1984-12-28
Abstract: PURPOSE:To find the deterioration of a radiation detector composed of a semiconductor accurately in its early stage by judging the deterioration of the radiation detector on the basis of the level of the leak current of the radiation detector. CONSTITUTION:When a semiconductor detector (SSD) 23 is irradiated with no radiation, the SSD23 is biased reversely by a resistance 25, so only a leak current i0 flows to a leak current amplifier 39. When the SSD23 is irradiated with radiation, on the other hand, an impulsive signal current ix is generated. This signal current ix flows to a charge amplifier 31 through a capacitor 27, but does not flows to the amplifier 39. Therefore, only the leak current i0 flows to the amplifier 39. Then, this leak current i0 is amplified by the amplifier 39 and inputted to the comparator in a warning indication device 33. When the SSD23 deteriorates and the leak current increases, the output of the amplifier 39 increases above a reference value and the device 33 generates a warning.

Title: Continuous pickling method
Inventor: YANAGI KENICHI
IPC: C23G1/02
Filed: 1985-12-09
Abstract: PURPOSE:To shorten the time for pickling by heating a material to be pickled to a high temp. then blowing the jet of an acid soln. to the material so that the scale on the surface of the material to be pickled is made easily peelable. CONSTITUTION:The material to be pickled is heated to the temp. above the b.p. of the acid soln. under the atm. pressure. The heated material to be pickled is pickled by blowing the jet of the acid soln. to the material to be pickled while the material is not held immersed into the acid soln. The scale on the surface is finely cracked at the moment when the jet of the acid soln. is splashed onto the material to be pickled. The scale is peeled by the quick expansion of the gas generated when the acid soln. intruding into the cracks evaporates. The time for pickling is thus shortened.
