Title: Peak level discriminator
Inventor: KOURA MAKOTO
IPC: H03K12/00
Filed: 1990-11-26
Abstract: PURPOSE:To detect a peak level of an input signal without a time delay when it is lower than a specified value by comparing a deviation signal between a reference signal and the input signal with a low level reference signal. CONSTITUTION:A reference signal generating circuit 5 generates a reference signal 1a synchronously with an input signal 3a and of the same waveform and a prescribed constant level. The input signal 3a and the reference signal 1a are subtracted by a subtractor circuit 6 and a deviation signal 1b of a peak level is inputted to an absolute value amplifier circuit 1, from which an absolute value signal 1c is obtained. The absolute value signal 1c is compared with a low level reference signal 3c outputted from a low level reference signal generating circuit 2 at a voltage comparator 3 and when the absolute value signal 1c exceeds the low level reference signal 3c, the polarity of the low level detection section 1d being an output of the voltage comparator 3 is inverted. Thus, it is not required to provide a margin time for level discrimination and the level decrease in an input signal is detected at a high speed.

Abstract: PURPOSE:To prevent sludge from being accumulated in a cutting oil tank by dividing the cutting oil tank into three, namely, a dirty tank in a conical shape, a clean tank plenum chamber and a clean tank furnished with a stirrer. CONSTITUTION:Cutting oil recovered from the circumference of the bed of a machine tool is housed in a dirty tank 2a, the aforesaid cutting oil is then forwarded into a magnetic separater 5 by a circulation pump 4, massive cutting chips are separated out of the cutting oil, and they are filtrated by a paper filter 7 so as to allow fine metallic matters to be filtrated thereafter, so that they are then forwarded to a setting tank 12. In this case, the fine metallic matters are settled, let the rest of them falls down into a clean tank plenum chamber 2b thereafter, and it is then shifted to a clean tank so as to be stirred, so that it is then fed into a machine tool again by means of a pressure feed pump 4. In this case, when the oil level of the cutting oil within the clean tank plenum chamber 2b goes across the definite level, the oil overflows into a dirty tank side, therefore fine sludge floating over the oil surface is returned back to the dirty tank 2a, and the amount of shortage of the cutting oil is thereby supplemented to the clean tank.

Abstract: PURPOSE:To facilitate the detection of a LSI having a small operation margin by supplying or extracting a bypass current to a constant-current passage in an internal voltage generator, and controlling a generated internal voltage from an exterior. CONSTITUTION:When a voltage is applied to external terminals A, B to supply a current from a transistor TrQ11 to a node n1, the base voltage of a TrQ1 is reduced, and the generated voltage VCS of a TrQ8 is decreased. On the other hand, when external terminals C, D are controlled to turn ON a TrQ12, the base potential of the TrQ1 is raised to rise the generated voltage VCS. When external terminals E, F are controlled to turn ON a TrQ13 to supply a current to a node n2, the potential of the node n2 is raised. generated voltage VBB is raised, an external terminal G is controlled to turn ON a TrQ14 to extract a current from the node n2. Then, the potential of the node n2 is reduced to decrease the generated voltage VBB. Thus, the levels of the generated voltages VCS, VBB are freely varied to intentionally reduce its operation margin, thereby easily detecting an LSI having a small margin.
