Abstract: PURPOSE:To measure the displacement state of a stage with high accuracy tolerant to impact vibration, etc., by engraving a line on diffraction grading in part of the slide part of the stage, making diffracted light of specific order which is generated by the diffraction grating interfere, and detecting the light and shade based upon the interfering light. CONSTITUTION:The diffraction grating 11 having a grating array in the moving direction of the slide part 1 is provided on a flank of the slide part 1 of the stage to be positioned. A detection head 12 is fixed arranged on the slide part 1 and the coherent luminous flux from a laser 13 is collimated by a collimator lens 14 into parallel luminous flux; and a beam splitter 15 splits the parallel luminous flux into two pieces of luminous flux, i.e. reflected luminous flux and transmitted luminous flux, which are made incident on the diffraction grating 11 and diffracted. The reflected and diffracted light beams are made to interfere with each other and a photodetector 19 detects the light and shade of the interfering light. The light and shade of the interfering light detected by the photodetector 19 are counted to measure the quantity of movement of the slide part 1.

Title: Liquid feeding device and automatic analyzer
Inventor: KOIDE AKIRA
IPC: G01N35/10
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To smoothen the flow of bubbles and to inhibit the fluctuation of pressure by dividing a face at a side opposite to a diaphragm, of a liquid feed chamber into almost two, forming an inlet on a peripheral portion of one side thereof, and an outlet on a peripheral portion of the other side, and mounting the inlet and outlet valves integrally with the liquid feeding chamber in such manner that they are unevenly distributed on a peripheral portion of the liquid feeding chamber. SOLUTION: To replace the gas in the liquid feeding chamber 131 of a liquid feeding device with the liquid, a liquid introducing device is connected with an inlet 144 of the liquid feeding device, and the liquid is pressurized and fed into the inlet 144, so that the pressurized liquid reaches an inlet valve 132 through the liquid passages 143, 134, 122. The liquid is flowed into the liquid feeding chamber 131 when the inlet valve 132 is opened by the pressure of the liquid, the gas existing in the inlet portion is pushed and flowed to a flat plate passage, and the inlet portion is filled with the liquid.  The gas in the liquid feeding device is sucked by a vacuum device connected with a discharge nozzle 111, on this occasion, the gas is sucked through an outlet valve 121 which is opened when the back pressure of the outlet valve 121 becomes lower than the internal pressure of the liquid feeding chamber 131.

Title: Automatic bias current adjusting circuit
Inventor: KIMURA MASASHI
IPC: G11B5/03
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of heat of erase head and the generation of distortion of an erase current waveform by sending a signal obtained by detecting the level of an erase current to an automatic bias current adjusting circuit and then compensating for a control voltage to control the level of bias current depending on the level of erase current. SOLUTION: An erase current flowing to an erase head 27 is detected by a current detecting resistor R6, it is then rectified and smoothed by a diode D1 and a capacitor C4 and is then sent to a reference voltage control circuit 3 via a level detecting circuit 2. The reference voltage control circuit 3 compares the output with the reference voltage of erase signal and then sends a difference to a level detecting circuit 5 via the reference voltage generating circuit 4. The level detecting circuit 5 sends a difference signal obtained by comparing the bias level signal from the bias detecting circuit 22 with the reference voltage of bias signal to a bias oscillation circuit 25 via a variable power supply circuit in order to control its output level. In this case, an output level is compensated by the signal from the reference voltage generating circuit 4.

Abstract: PURPOSE:To obtain a picture of even quality regardless of the level of the background temperature of a subject to be picked up, by providing a short wavelength pass filter which cuts the wavelength shorter than the cut-off length of a long wavelength of all infrared detectors on the photodetecting surface of a solid- state image pickup element. CONSTITUTION:A short pass filter 5 which absorbs the components having lengths longer than the cut-off wavelength among incident infrared rays 4 is attached close to the photodetecting surface of an IRCCD consisting of an infrared detector 2 and a charge storage/transfer part 3 which are provided on a cooled substrate 1 positioned on the focal plane of a light receiving optical system 6. The cut-off wavelength of the filter 5 is set shorter than the cut-off wavelength lambdap of all infrared detectors 2 on the IRCCD. Furthermore the temperature of the filter 5 is approximately equal to that of the cooled substrate 1 owing to the close adhesion of the filter 5. As a result, the infrared rays radiated from the filter 5 itself can be reduced satisfactorily.
