Title: Multiwavelength spectrophotometer
Inventor: KAWAMOTO AKIRA
IPC: G01N21/27
Filed: 1985-12-23
Abstract: PURPOSE:To make it possible to remove a measuring error due to stray light trouble in an ultraviolet region by performing measurement from the ultraviolet region to a visible region at a high speed, by mounting a first beam source and a second beam source and alternately outputting beams from both beam sources to the same beam path by a photosynthesizer. CONSTITUTION:Ultraviolet rays from a D2 lamp 1 being a first beam source are made intermittent by a first beam chopper 2 and transmitted through a beam splitter 3 to be condensed by a condensing lens 4 and incident to a specimen cell 5. The beam from a Xe lamp 6 being a second beam source passes through a heat ray cutting filter 7 to be converted to beam containing only a visible part and is made intermittent by a second beam chopper 8 and, thereafter, reflected by the splitter 3 and condensed by the lens 4 to be incident to the cell 5. These beams pass through the cell 5 and are subsequently condensed by a condensing lens 9 and passed through a multiwavelength spectrometer slit 10 to be dispersed by a concave diffraction lattice 11. A photodiode array 12 is arranged to the image forming surface of said dispersed beams and beam with each wavelength is received by the beam receiving element provided so as to be opposed to said array 12. By this method, a measuring error can be removed.

Title: Magnetic recording and reproducing device
Inventor: MIYATA MASANORI
IPC: G11B5/588
Filed: 1985-12-20
Abstract: PURPOSE:To reduce the influence of hysteresis characteristic of a piezoelectric element and to evade track jump by supplying a position holding signal to the element only for one trace period from the timing of a detecting pulse signal outputted immediately before switching a variable range of a driving control signal when a reproducing signal is changed over. CONSTITUTION:An edge detecting pulse in one field immediately before a driving control signal in a reproducing mode switching period T in which a mode change detecting pulse is outputted is turned to a signal included in the succeeding reproducing mode changing range is inputted to a monomultiplexer 17 by an AND gate 16 at the time of switching the reproducing mode, and a high level switching pulse is outputted to a switch 4 only for one-field period from the edge detecting pulse. Thereby, a position holding signal for a power supply 3 is supplied to piezoelectric elements 10, 11 in reproducing tracing to correct the driving voltage. Since the voltage impressed upon the elements 10, 11 is returned to the voltage on the intermediate position of the changing range, transfer to the succeeding reproducing mode under the state impressing a high voltage can be suppressed, the influence of hysteresis characteristic of the piezoelectric elements 10, 11 can be reduced, efficient reproducing can be attained, and the track jump can be suppressed.
