Abstract: A blood collection device including a sealed area with a soluvated, non-aqueous anticoagulant composition positioned therein. The preferred anticoagulant composition comprises heparin, polyethylene glycol and optionally, deionized water and one or more salts.

Abstract: A liquid crystal display device includes a pair of electrode substrates at least one of which is transparent, a display medium having a liquid crystal region surrounded by a polymer region, and a plurality of pixels. The display medium is interposed between the pair of substrates. A difference between an upper limit value and a lower limit value of a phase transition temperature between a liquid crystal phase and an isotropic liquid phase of a liquid crystal composition constituting the liquid crystal region is 7.0.degree. C. or more.

Abstract: A copying machine allowing high copying efficiency and reliability by feeding recording sheets from any of a plurality of recording sheet storage regions to an image transfer region at a constant timing. Recording sheets stored in a cassette are fed one by one to a conveyance path by a sheet feed roller. The recording sheets P retained in an intermediate tray are fed one by one to a conveyance path by a sheet feed roller. The timings at which the sheet feed rollers, which are first drive rollers, are driven are controlled in such a way that a register roller, which is a second drive roller, can be driven at a constant cycle time with respect to a plurality of recording sheets fed from the conveyance path. Even when the cassette and the tray are switched over, the register roller is driven always at a constant cycle time. Thus, the image forming operation can be executed by feeding recording sheets in synchronization with the image-reading timing.

Abstract: A sealed bag for vacuum-packing an electronic device in the state of being evacuated and partially thermally fused at an opening thereof includes a multi-layer film including; a first anti-static layer; a thin metal layer; an insulative layer; and a second anti-static layer. A container includes a case for accommodating at least two such sealed bags. The case is provided with a charge protective layer on an inner surface thereof; a housing for accommodating at least two cases; and a master carton for accommodating at least one housing.

Abstract: An oscillator generates a rectangular wave, based on which sawtooth waves are produced. When a synchronizing signal which is created when a laser beam from a laser diode is incident on a photosensor, is detected, a voltage of one of the sawtooth waves is sampled to hold it as a sample-hold signal. Comparators compare the sample-hold signal with the sawtooth waves, and a flip flop alternately outputs one of the compared results, to produce a pixel clock which regularly keeps a constant time relation to the synchronizing signal.

Abstract: A method of manufacturing a magnetic recording medium having at least a magnetic layer, optionally by means of an underlayer, on a non-magnetic substrate, and occasionally having a protective layer disposed on the magnetic layer, comprises irradiating to the surface of the non-magnetic substrate, the underlayer, the magnetic layer, the protective layer or the magnetic recording medium, a laser beam from a semiconductor laser module that moves relatively to the non-magnetic substrate, thereby applying a texturing; and a semiconductor laser texturing apparatus comprises a substrate rotating mechanism, a semiconductor laser module including a semiconductor laser beam source, a collimator for converting a semiconductor laser beam into a parallel beam and a light focusing mechanism for irradiating the laser beam to a projection-forming surface of a substrate supported rotatably by the substrate rotating mechanism, and a relative moving mechanism for the substrate supported rotatably by the substrate rotating mecha
