A method for transferring water upwardly and distilling it and/or of generating electricity by harnessing the heat of sunrays. The method includes placing a panel or a sheet which permits sunrays to pass therethrough near a water surface, evaporating the sea or lake water by heating it with sunrays passing through the panel or sheet, then, letting the steam thus produced rise up to a higher level due to its pressure. The steam is then cooled down to produce distilled water and/or, it is used to generate electricity.

This invention relates to an apparatus for analyzing cells in a biological liquid sample, such as blood, in which apparatus a flow passage in a sample pretreatment system can be shortened with a simple construction. A sample metering chamber, a mixing chamber and a measurement liquid extracting chamber are formed in a rotary sliding member of a pretreatment portion. The rotary sliding member is intermittently rotated so as to shift a sample from one chamber to another to perform a necessary treatment. Fluorescence or scattering light with respect to the sample, mixed with a reagent in the pretreatment portion, is detected by a flow cell.

A lithographic method and a lithographic apparatus ar disclosed in which the height of a silicon wafer making up an object of lithography is accurately measured. A lithographic apparatus such as an electron beam apparatus having a height-measuring instrument built therein is effectively used for forming a pattern on the order of submicrons.

A pipetter capable of mixing liquids and dispensing the mixed liquid has a pipetting tube, an actuating device connected to the tube for sucking liquid into and discharging liquid from the tube, and a flow disturbance device in the tube spaced from the discharge and suction end thereof and adapted to cause longitudinal mixing of liquid in the tube when liquid is moved along the tube in at least one direction. Mixing is effected in the tube by causing a liquid body to move repeatedly to and fro along the tube so that during each such movement at least a portion of the liquid body passes the flow disturbance device and the liquid body is not discharged from the first end of the tube. The pipetter is useful for example in mixing a suspension of blood cells with a reagent prior to analysis.

According to the present invention, the accuracy of particle size histograms produced from data relating to an impedance variation (Coutler Counter Method) caused by particles passing between electrodes disposed on either side of an orifice through which the particles pass is improved by excluding false data from the data used in producing the histograms, the false data resulting from more than one particle being resident in the orifice at a given data collection time. The preferred embodiment employs a light detecting method and apparatus to detect false readings and to provide correction information used to correct data obtained by the Coulter Counter Method and apparatus.

An optical device for illuminating an object with a rectangular pattern having a uniform light intensity distribution includes n (n.gtoreq.1) polarization separating elements which a laser beam emitted from a laser source enters and each of which separates the laser beam into two beams in two directions. The angle of separation by the polarization separating element is set to be 2.sup.(n-1) times of the smallest one of the separation angles of the polarization separating elements used. At least one quarter-wave or half-wave plate is combined with the polarization separating elements. An imaging lens is provided for forming 2.sup.n beam spots on the object such as an optical laser disk plate.

Particles contained in a liquid sample are analyzed by moving the particles along a detection passage past a detector using a liquid flow in the detection passage. To reduce the time required for analysis of each sample, the sample is delivered at an input location at the upstream end of the detection passage by movement of a movable container carrying the sample to the input location. Immediately after the commencement of the delivery of the liquid sample, liquid flow is caused to occur in the detection passage. Washing liquid is supplied to the input location by a liquid supplier different from the movable container which carries the sample.

A filter and filtering apparatus for measuring the deformability of a blood cell passing through a flow passage formed as a space between a surface of a groove formed in a first substrate and a surface of a second substrate with which the groove is sealed. The filtering apparatus includes electrodes mounted at the inlets and outlets of the flow passages, or optical elements to enable cell deformity measurements.

This invention provides an automobile tire with communicating holes bored from the tire's tread to the sides of the tire. These holes permit snow or water which has come under the tire to be discharged to the outside through these communicating holes, thereby contributing to prevention of the tire's slip. For more effective discharge of snow or water, a well sliding surface material is applied on the inner surfaces of the communicating holes.

The invention relates to a capacity control method for controlling the capacity of a multistage compressor in response to a flow rate signal by varying the openings of vanes at individual stages. The relationships of the openings of the vanes of the individual stages are made to vary in response to the flow rate signal from the multistage compressor. Thus, when the flow rate of the multistage compressor is far from the anti-surge capacity within the operable range thereof, it is possible to select vane opening relationships which provide the highest efficiency for the multistage compressor. When the flow rate of the multistage compressor drops to either a value near the anti-surge capacity or the inoperable range, on the other hand, it is possible to select vane opening relationships which provide an enlargement of the operating range of the multistage compressor, before the flow rate enters that inoperable range.
