Abstract:
Measurement of a mass flow rate is accomplished by equalizing the output amplitude values of upstream and downstream sensors without causing a lowering of the mechanical Q of a vibration system. One of the upstream and downstream sensors includes a permanent magnet disposed on a side of a tube and an induction coil disposed on a side of a base, the output voltage amplitude of which is fixed. Another sensor includes a ferromagnetic member disposed on the side of the tube and an excitation coil and an induction coil disposed on the side of the base. The output voltage amplitude of the induction coil is controlled to be coincident with the output voltage amplitude of the induction coil by adjusting a DC current flowing through the excitation coil.
Abstract:
A spectrophotometer 10 includes built-in detector 24 and external detector 32. When a mountable/removable optical path switcher 23a is installed in a specimen chamber 23, measurement based on detection signals from built-in detector 24 is replaced by measurement based on detection signals from external detector 32. The spectrophotometer further includes a measurement data threshold-value storage unit 51 that stores threshold value T for measurement data from built-in detector 24 or external detector 32, and a light-receiving detector recognition unit 52 that recognizes which detector is able to receive the measuring light beam based on the results of a comparison between threshold value T and measurement data from built-in detector 24 or external detector 32 while the measuring light beam is being introduced into specimen chamber 23.
Abstract:
To enable alignment of a magnetic pattern of a pair of master disks and a magnetic recording medium, each of the master disks has at least a pair of alignment marks disposed outside the region of the magnetic pattern. The master disks can be optically transparent or semi-transparent. The master disks can be aligned while the alignment marks are externally observed.

Abstract:
Described is a heterocycle-containing carboxylic acid derivative represented by the following formula (I): wherein A represents, for example, a heteroaryl group which contains at least one nitrogen atom and may have a substituent, B represents, for example, a heteroarylene group, a —CONH— group or a group represented by the formula —CR6═CR7— in which R6 and R7 represents H, a lower alkyl group or the like, D represents an arylene group, a heteroarylene group or the like, n1 stands for 0 or 1, M represents, for example, a hydroxyl group or a lower alkoxy group; or a physiologically acceptable salt thereof. As a retinoic-related compound replacing retinoic acid, it permits the provision of a preventive and/or therapeutic for various diseases.
Abstract:
The precision of phase difference obtained by a phase difference calculating unit is improved by correction through outputs of a frequency ratio calculating unit and a temperature calculating unit considering that the phase or time difference of each output signal of a vibration sensor indicating the mass flow or density of a fluid is a function of the temperature and axial force on a measurement pipe, or that the axial force is a function of the ratio between two resonant frequencies.
