Title: Retrieving device for information track
Inventor: WATANABE KATSUYA
IPC: G11B7/085
Filed: 1986-01-14
Abstract: PURPOSE:To retrieve an information track with high accuracy and high stability by detecting the number of tracks where a light beam crossed on the signal of a means which divides the signal of a track shift detecting means by the signal corresponding to the light quantity irradiated on said shift detecting means. CONSTITUTION:A differential amplifier 14 changes its amplitude in proportion to the change of the reflected light quantity of a recording carrier 7. The output (c) of a divider 19 obtained by dividing the output (a) of the amplifier 14 by the output (b) of a synthesizing circuit 26 equivalent to the reflected light quantity is kept at a fixed level. Thus the output (c) has a fixed degree of margin to the reference level for comparison of a comparator 31 in a retrieving mode. Then the outputs of the comparator 31 and a pulse generator 32 are delivered with high stability and high accuracy against an optical beam 2 crossing a track. Therefore, the signal which detects the track cross of the light beam is kept at a fixed level despite the change of the reflected light quantity of the carrier 7. Thus it is possible to count accurately the number of tracks were the light beam crossed in a retrieving mode.

Title: Optical information reproducing device
Inventor: AKAHORI HIROSHI
IPC: G11B7/09
Filed: 1986-01-14
Abstract: PURPOSE:To secure a high reproduction S/N by preventing the reflected light sent from the surface at the side of light irradiation of a substrate from making incident on the light receiving surface of a photodetector. CONSTITUTION:A slit 8 is formed at the focus position of a condenser lens 7. The light radiated from a semiconductor laser 5 is turned into parallel beams by a collimator lens 6 and focused by an objective lens 3. These focused beams are transmitted through a light transmitting substrate 1 and irradiated on the signal surface of an information recording medium 1 in spots. While the light reflected by the signal surface is turned into parallel beams by the lens 3 and condensed by a condenser lens 7. These condensed beams are transmitted through the slit 8 to be focused on the slit 8 and then making incitent on the light receiving surface of a photodetector 9. The light reflected by a surface 2a of the substrate 2 at the side of light irradiation is dispersed and made incident on the lens 7. Thus these beams are cut off by the slit 8 and never made incident on the light receiving surface of the detector 9.

Abstract: PROBLEM TO BE SOLVED: To certainly separate blood plasma by mixing an aq. soln. of inorg. salts and amino acids or salts thereof with whole blood in a specified vol ratio of whole blood or less so that the concn. of inorg. salts and amino acids or salts thereof becomes specified concn. to centrifugally separate the resulting mixture. SOLUTION: Inorg. salts, amino acids and salts thereof have action accelerating the separation of blood corpuscles and blood plasma in whole blood to lower a hematocrit (HL agent). The addition amt. of the HL agent to whole blood is set so that the concn. of the HL agent is about 20-200μmol per 1m of whole blood and the addition amt. of an aq.. HL agent soln. is set to 20vol% or less of whole blood. The HL agent and the aq. HL agent soln. are mixed and, subsequently, a blood corpuscle component is centrifugally separated. Since the vol. of red corpuscles is reduced by adding the HL agent and an amt. of free blood plasma is increased, the recovery of blood plasma is enhanced.

Filed: 1980-01-21
Abstract: PURPOSE:To enable a low bar code to be surely read as well without increasing the size of an apparatus by enabling perfect code information to be obtained by connecting scanning information on a plurality of imperfect scanning lines. CONSTITUTION:When an article 7 attached with a bar code label is placed in a scanning window 6, a light beam l is irradiated from a light source 1 to a rotary mirror 4 and the bar code label of the article 7 is scanned by way of stationary mirrors F1-Fn.

Title: Combined de-emphasis circuit and noise blanker
Inventor: GUREGORII JIYON MANRABU
IPC: H04H20/88
Filed: 1990-01-12
Abstract: PURPOSE: To reduce the noise of a de-emphasis circuit by generating a flag for the period of short-time noise after detecting the noise time and holding extracted signals through the period of the flag so that no noise pulse can pass through a dual mode circuit. CONSTITUTION: A noise detector incorporates a flag generating circuit constituted in the form of an ultrasonic noise detector 66 and a signal intensity noise detector 67. A band-pass filter 68 passes the ultrasonic noise of composite signals and the composite signals are then rectified. A low-pass filter 72 averages, the rectified signals and sends the average value to a comparator 76. Pulses or non-averaged signals are damped and compared with the average value. The comparator 76 generates an output, namely, the flag when the damped noise spike rises from the average value. A dual mode circuit is a primary low-pass filter when a clock signal advances and becomes a sample-and-hold circuit when the clock signal stops under the presence of the flag. Therefore, the dual mode circuit gives an ideal rank for noise reduction.
