Title: Image reader
Inventor: HORI FUSAO
IPC: G06T5/00
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To provide an image reader with which a threshold value in the case of binarizing a read image is hardly adversely affected even when dust is stuck on a reference white panel. SOLUTION: An optical reading system 12 is arranged while being opposed to one side of contact glass 9, and the focal position of the optical reading system 12 is matched with the other side of the contact glass 9. An original 2 is in contact with the other side of this contact glass 9. The optical reading system 12 is moved parallel through a moving mechanism while keeping constant a gap with the contact glass 9. A reference white panel 22 is provided on one side of the contact glass 9 as mentioned above. Therefore, since the focal point of the optical reading system 12 is not matched with the reference white panel 22, even when dust (a) is stuck on the reference white panel 22, the image of the dust (a) is not formed on an optic/electric converting element 14.  Thus, the adverse influence from the dust (a) is hardly exerted and the threshold value can be determined by performing reading just once.

Title: Diluted solution composite used for reverse passive hemagglutination test
Inventor: MOTODA AKISAKU
IPC: G01N33/574
Filed: 1981-01-13
Abstract: PURPOSE:To increase the agglutination titer of a sensitized erythrocyte, by using a physiological salt solution buffered with weak acidic phosphate and added with calcium chloride as a diluent, in order to measure alpha-Fetoprotein by reverse passive hemagglutination. CONSTITUTION:Although the agglutination titer of the sensitized erithrocyte tends to increase as the concentration of calcium chloride increases, the amount of addition is usually preferable to be in the range of 0.05-1.0 mili mole, since a white precipitate of calcium phosphate is formed by excessive addition of calcium chloride. Besides, it exhibts a remarkable effect to make acidic the salt solution and to allow calcium chloride to dissolve easily in increasing the agglutination titer of the sensitized erythrocyte by calcium ion. As a pH controlling agent of the diluent, HEPES, sodium hydroxide, etc. can be used in addition to sodium mono-and diphosphate.

IPC: H04B1/16
Filed: 1991-01-18
Abstract: PURPOSE:To always obtain a proper dynamic range and to allow the user to easily listen to a weak sound from the audio equipment regardless of the acoustic state in a cabin such as a position of a sound volume knob and a degree of a noise level. CONSTITUTION:A compressor 2 compresses a dynamic range of an input signal from a signal source 1. A sound volume position detection device 7 detects the sound volume position of a sound volume control 3 and its detection signal is inputted to a control circuit 8. The control circuit 8 controls the compressor 2 to increase the compression of the dynamic range at a region where an input signal level is small as the sound volume position of the sound volume control 3 indicates a small sound volume. As a result, when a sound with a small input signal level is hardly heard, an output signal level from the compressor 3 is increased and a weak sound becomes easy to listen.
