Filed: 1985-03-06
Abstract: PURPOSE:To enable measurement of correct displacement regardless of the deformation of a scale, by arranging detectors on both sides of a scale facing each other and a signal processing means which add up signals from the detectors after pulsated. CONSTITUTION:Signals S1 and S2 outputted from magnetic detectors 2a and 2b are amplified with first stage amplifiers 3a and 3b to be deformed into pulse signal Sp1 and Sp2 with waveform shaping circuits 4a and 4b and then, pulses of the respective pulse signals Sp1 and Sp2 are counted with counters 5a and 5b.

For example, when a scale 1 bends in such a manner as to extend on the side of the magnetic detector 2a while reducing on the side of the detector 2b as illustrated, the counters 5a and 5b give 4 and 8 in the counts respectively. In other words, the detectors 2a and 2b work complementarily against any deformation of the scale 1 to ensure that the output of the having circuit 7 is invariably equivalent to the counts would be given as if no deformation took place in the scale and thus, correct displacement can be determined.

Further amounts of zinc oxide may be admixed mechanically or be present as a coating on the catalyst tablets. The catalyst is especially well suited for conversion of carbon monoxide with steam to hydrogen. The catalyst is produced by precipitation of copper- and aluminum salts at pH=6.0-6.5 during addition of an ammonium carbonate solution. After filtration and drying, the product is calcined at 750 DEG -850 DEG  C. until there is obtained a product having a 60-100 percent spinel structure. Zinc salt is introduced in the pores of the spinel, and the product thereby formed is heated up to at least the decomposition temperature for the zinc salt which is then converted to zinc oxide. Possible addition of zinc oxide in addition to that introduced into the pores of the spinel may be admixed mechanically.

Title: Calibration of percutaneous gas monitor
Inventor: KUWA KAZUHIRO
IPC: A61B5/1495
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To shorten the time for calibration and to improve the calibration accuracy by calibrating only one point usually and obtaining a calibration value of the other point from a calibration result stored in two-point calibration. SOLUTION: Connection of a sensor is confirmed at first and calibration by first gas is carried out. Next, identification information of a sensor is read out from an identification memory to confirm whether the sensor is the one to which calibration data are registered or not. When the sensor is used for the first time, two point calibration is carried out since calibration data are not registered in the memory. On the other hand, when the sensor is the one to which calibration data are already registered, registered data are read in. The date and time when the former two-point calibration was carried out among the registered data are used to judge whether a prescribed period is elapsed from the date and time or not. When the prescribed period is over, two-point calibration is carried out. However, when it is within the prescribed period, only on-point calibration is carried out to obtain only one calibration value (high range value).
