Abstract: To realize a coordinate reading apparatus which is capable of easily setting a particular function to a switch provided on a coordinate indicator, and an interface unit and a coordinate reading system for the coordinate reading apparatus. A coordinate detecting section 21 detects a coordinate value for a position indicated by a coordinate indicator 3 and a switch status. A function selecting means 22 determines that a menu provided on a tablet 2 is read from the coordinate value and the status, to store functional data assigned to the menu in a memory means 23. A conversion status determining means 24 determines that the inputted status coincide with the status to be converted stored in the memory means 23, to notify coincidence to a conversion status output means 25. Receiving the notification, the conversion status output means 25 outputs data to be outputted stored in the memory means 23 instead of inputted switch status.

Abstract: By use of an excitation beam having a wavelength which is equal to, or close to, the sizes of particular particulate substances as the object of analysis, the particulate substances such as an immunoreaction product between an antigen and an antibody or between the antigen and a material supporting the antibody thereon are detected selectively. Very small particles having specific sizes such as rheumatuid factors, cancer specific antigens can be detected with high sensitivity.

Abstract: This invention relates to a method and apparatus for positron extinction analysis which irradiates a positron beam to a sample to be analyzed through a convergent lens system consisting of a magnetic lens and measures the extinction .gamma.-rays generated from the sample for the positron extinction analysis. The invention utilizes the property of the magnetic lens of an electron microscope that the magnetic lens has the same focal distance for both the positron and the electron having mutually the same energy. If the magnetic lens of the electron microscope is used as a convergent lens system for a positron beam, the positron beam can be radiated highly accurately to a very small, local position of the sample which is being observed through the electron microscope. For instance, in the case of a transmission type electron microscope, the convergent lens system of the electron beam is used as a convergent lens system of the positron beam.

Abstract: A medium including particles to be analyzed is contained in a cell through which excitation rays are passed. The excitation rays are focused and have a predetermined wave form. A period in time of the excitation rays is set substantially equal to and preferably longer than the attenuation time of an acoustic pulse which is generated when the excitation rays are absorbed in the particle and when the particle release heat. The acoustic pulse is used to analyze particle size and number of particles.
