Title: Cell for infrared absorption measurement by using silicon waveguide with formed concentrated membrane
Inventor: SEYAMA TOMOKO
IPC: G01N21/27
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a cell, for infrared absorption measurement, which does not require a pretreatment such as chromatography to sample water in order to quickly detect and analyze an organic substance in a small amount contained in the water by an infrared absorption measuring method, which is provided with a new sampling method or a new device and which uses a silicon waveguide on which a concentrated membrane is formed. SOLUTION: This cell 15 is constituted in such a way that a silicon waveguide 8 on which a concentrated membrane 6 used to selectively take into an organic substance from water via a silicon oxide layer 7 is formed is situated in the lower-layer part of the cell 15 for infrared absorption measurement and that an infrared-ray introduction crystal element 9 which is used to introduce infrared rays 10 into the silicon waveguide 8 is arranged on a face on which the concentrated membrane 6 on the silicon waveguide 8 is not formed. In addition the upper-layer part holds a liquid sample when the concentrated membrane 6 and the liquid sample are brought into contact in order to measure the liquid sample. That is to say, an O-ring 4, a liquid sample reservoir 5, a sheet 3 and an aluminum lid 2 comprising liquid-sample introduction ports 1 are laminated. Thereby, even when sample water is introduced without its pretreatment, an infrared absorption measurement can be performed.

Title: Mass flowmeter
Inventor: SHINODA YUJI
IPC: G01F1/84
Filed: 1989-06-26
Abstract: PURPOSE:To automatically adjust a zero point by automatically adding a compensating input to obtain an output value which is to be obtained when the flow rate is zero. CONSTITUTION:When a switch 13 is turned ON with the flow rate set zero, an FF12 is set, and counters 10, 11 count the number of pulses from an oscillator 9 by a Q output of the FF12. The outputs from the counters 10, 11 are input to a T3 terminal of a variable resistor 7 equipped with a memory. On the other hand, the Q output from the FF12 is input to a T2 terminal of the variable resistor 7 thereby to release the lock of the variable resistor. Therefore, the variable resistor 7 is increased or decreased in accordance with an input from the T3 terminal. The increasing/decreasing direction is determined by an input to a T1 terminal. An output from the variable resistor 7 is added to a signal of a detector by an operational amplifier 4 and output therefrom. Whether the output from the variable resistor 7 is positive or negative is detected by a comparator 2. Depending on the result of the comparison, a command is generated to the T1 terminal of the variable resistor 7 to change the output so that the output from the operational amplifier 4 becomes zero. After a predetermined time later, the counter 11 overflows and the FF12 is reset thereby locking the variable resistor 7.

Title: Waveform recovery circuit for pulse amplitude modulation wave
Inventor: KINOSHITA HITOSHI
IPC: H03K9/02
Filed: 1989-06-26
Abstract: PURPOSE:To obtain a waveform recovery circuit for a pulse amplitude modulation wave with simple circuit constitution by outputting a waveform recovery signal from an output terminal of an operational amplifier. CONSTITUTION:An inverting input terminal of an operational amplifier A10 connects to its output terminal and one terminal of a 1st capacitor C10, and the other terminal of the capacitor C10 connects to an output terminal of an analog switch circuit S10 with a pulse amplitude modulation wave supplied therethrough and one terminal of a resistor R10. Then the other terminal of the resistor connotes to a reflection terminal of a 2nd capacitor C11 connecting to a noninverting input terminal of the operational amplifier A10 and a reference level, and a waveform regeneration signal is outputted from the output terminal of the operational amplifier A10. Thus, when a pulse amplitude modulation signal supplied intermittently corresponding to the on/off operation of the analog switching circuit is smoothed corresponding to the envelope, the input signal is supplied directly to a filter circuit without holding the input signal once into a holding capacitor. Thus, the waveform recovery circuit for a pulse amplitude modulation wave with simple circuit constitution is obtained.

Abstract: PURPOSE:To automatically execute an optimal left/right pincushion distortion correction by varying the amplitude of a distortion correcting signal of a parabolic waveform superposed on a horizontal deflection current in accordance with the adjustment amount of vertical raster width. CONSTITUTION:When width h1 of a vertical raster is adjusted greatly to with h2, a vertical width adjustment value signal (ei) is inputted to a distortion correcting signal amplitude adjusting circuit 11 from a vertical width adjusting circuit 1, and the distortion correcting signal amplitude adjusting circuit 11 inputs a signal (ci) obtained by enlarging a level of a raster distortion correcting signal (c) inputted from a distortion correcting signal generating circuit 6 to an inversion amplifying circuit 7. Accordingly, a correcting signal (di) of an inversion parabolic waveform is supplied to a horizontal deflecting circuit 8 from the inversion amplifying circuit 7, and a raster 10 becomes that which corrects its barrel distortion. Subsequently, when width (h1) of the vertical raster is adjusted small to width h3, its vertical width adjustment circuit 11, a level of its output signal (ci) is corrected small and a shape of the raster 10 becomes that which corrects a pincushion distortion. In such a way, a left/ right pincushion distortion can always be corrected.
