Abstract: Blood constituents are separated by centrifugation in a transparent tube which contains a float for physically elongating certain of the constituents. The centrifuged sample in the tube is positioned on a layer measuring device with which red cell and buffy coat constituent band heights can be measured in ambient light. The buffy coat constituent measurements are made under optical magnification. The measuring device has a mathmatically derived red cell layer nomogram printed thereon, and a separate scale for measuring buffy coat constituent bands. Conversion tables are provided for converting the measured buffy coat constituent band lengths into constituent cell counts. The measuring device includes tube-engaging portions for properly positioning the tube during the measurements, and the red cell scale automatically compensates for the presence of the float and densification of red cells needed for proper banding.

Abstract: A dual-lumen catheter comprises an elongated cylindrical tube made of silicone and having an internal septum extending along the length thereof to form a pair of longitudinal lumens. A hollow conical tip is formed on the distal end of the tube with the outside surface of the conical tip merging smoothly with the outside surface of the tube, and the inside surface of the conical tip merging smoothly with the inside surface of one of the lumens. 
     The distal end of the other lumen is longitudinally spaced from the distal end of the tip. A reinforcing member is located inside the tube and extends along the length of the tube. The reinforcing member is made of a material which is substantially stiffer than the material of the tube so that the catheter can be advanced against a resistance by the applications of force to the proximal end of the catheter.

Abstract: Reagents are often stored in the closed end of a container. However, these containers tend to dislodge the reagent when they are dropped. Described herein is a container (10) having sidewall (14), a bottom wall (16) and a reagent (15) deposited on an inner surface (17) of the bottom wall (16). The sidewall (14) joins the bottom wall (16) at a junction (T). The container (10) is provided with means such as a flexible flange (18) for preventing shock from being transmitted to the bottom wall (16) when it strikes a hard object. The flange (18) is attached to the middle of the bottom wall (16) of the container (10) and is of sufficient height and thickness to absorb the impact of dropping the container from a height of 68.6cm on to a hard surface. The flange (18) does not interfere with the flexibility of the sidewall (14) when it is desired to squeeze it to assist dissolving of the stored reagent (15). Other shock absorber means are also described.

Abstract: A signal converter includes a frequency-to-voltage converter (20) for converting a frequency of an input signal (S) received via an input terminal (Tin) into a control voltage. The input signal contains a noise signal (N) having a frequency less than the frequency of the input signal (S). The control voltage changes in accordance with a change of the frequency of the input signal (S). A filter (30) has a variable cutoff frequency (CF) so that the noise signal (N) is eliminated from the input signal (S) and outputs a filtered signal. The variable cutoff frequency is changed in accordance with a change of the control voltage so that a change of the variable cutoff frequency follows a change of the frequency of the input signal (S). A comparator (10) compares the filtered signal with a reference voltage and converts the filtered signal into a pulse signal having a pulse width corresponding to the frequency of the input signal (S).

Title: Optical head having a hologram associated with the objective lens
Inventor: KATO MAKOTO
IPC: G11B7/13

Abstract: Disclosed is a compact optical pick-up head apparatus suitable for mass-production, which comprises a light radiation source (1), an element composed of photodetector (366) split into a plurality of regions and integrated on the same base, an objective lens (3) for focusing a beam from the above source on an optical disk, a blazed hologram integrated (2) to the support member of the lens, a means (3234) for driving the support member to which the objective lens and blazed hologram are integrated in response to an output as servo signal output from the photodetector which receives a diffracted beam produced in such a manner that a return beam reflected or diffracted by the optical disk is incident on the objective lens integrated with the above hologram. The optical pickup apparatus according to the present invention employs a region-split-type phase hologram in which a pair of Fresnel zone plate-like patterns, by which a plurality of diffraction wavefronts having a different focus and the same diffraction order are produced outside an optical-axis, are non-superimposedly formed. The above hologram can be blazed with a pinpoint accuracy by lithography using a few mask patterns synthesized by a computer, and further a more preferably blazing can be realized by the combination of the ion beam etching and the lithography. Accordingly, not only noise caused by an unnecessary diffracted beam component but also the offset of a servo signal can be restrained and the size of the objective lens can be reduced by the integration of the entire optical system, which greatly contributes to the superminiaturization of an optical head.

Abstract: To detect escape or spillage of a cold liquid, for example liquefied natural gas, a narrow, robust, flexible, resilient, plastics tube 4, placed where the escaped or spilled cold liquid can contact it, is filled with carbon dioxide gas from a gas supply 24 via a non-return valve 34 and a pressure regulator 30 which ensures that the maximum pressure in the tube 4 is at a desired value which is preferably greater than the pressure of the ambient atmosphere surrounding the tube. A gas pressure drop detector 38 is provided to observe a pressure drop in tube 4. Should escaped liquefied natural gas contact the tube 4 the latter is so cooled that the carbon dioxide gas inside de-sublimates to a solid of greatly reduced volume causing a marked drop in pressure in the tube 4. This is observed by the detector 38 which initiates a warning or some safety action. A gas flow restrictor 36 ensures the gas supply 24 cannot rapidly re-charge the tube 4 before the detector 38 has responded to the pressure drop.

Abstract: A spectrally selective, glare-reducing mirror for vehicles which consists of a substrate having a multi-layer coating which includes a thin, transparent dielectric layer, preferably of titanium dioxide at a thickness of 600-650 Å and a very thin layer of metal, preferably of aluminium or silver, at a thickness of from 25 to 150 Å. The dielectric layer is closest to a source of incident light to be reflected by the mirror. When applied to the rear surface of a transparent substrate such as glass, the metal layer may also be coated with light absorbing material such as paint for protection and reduction in unwanted reflections. With these preferred dielectric and metal layer thicknesses, a blue reflecting mirror may result having a glare-reducing luminous reflectance from 35% to 60%, while costs can be reduced due to lesser amounts of metal being required than in prior known mirrors.
