Title: Ion activity measuring apparatus
Inventor: TSUNEKAWA YUZO
IPC: G01N27/30
Filed: 1986-12-16
Abstract: PURPOSE:To prevent contamination with a liquid limited to a fixed level, by arranging a pair of sheet-shaped ion selection electrodes adapted to separate electrically and generate a potential to ions with the working surface thereof downward to keep them in contact with a liquid to be inspected and a reference liquid from below. CONSTITUTION:Three pairs of ion selection electrodes 11a-11c are arranged with the working surface thereof downward together with an upper frame 18 and combined with a nonwater permeating film 20, a porous member 16 and a lower frame 21 while two openings 12 of the upper frame 18 are made to conduct with a bridge 19 to form, a measuring device. A liquid to be inspected and a reference liquid are injected separately into the two openings 12 of the upper frame 18 to fill a groove 14 of the lower frame 21 through an opening 13 of the film 20. The liquids are allowed to permeate the porous member 16 and passes through openings 15a-15c from a protrusion of the member 16 to contact the working surfaces of the ion selection electrodes (pairs) 11a-11c. Then, ion activity is measured from a potential difference between electrodes of each pair of electrodes 11a-11c. The downward layout of the working surfaces of the ion selection electrodes (pairs) limits a contact range of the liquid in an electric connection area thereby preventing contamination.

Title: Cassette auto-changer and bar code read method
Inventor: TSURUMAKI NOBUHIRO
IPC: G11B23/30
Filed: 1993-11-05
Abstract: PURPOSE:To surely read the bar code of a cassette in a short time by correcting the read position of the bar code based on the read position of the bar code read just before or positions of bar codes read before. CONSTITUTION:In the cassette auto-changer, a bar code 11 of a first cassette is read in the scanning position -8mm off, for example, a scanning reference position P0 preliminarily stored in a memory. Next, the cassette auto-changer sets this scanning position -8mm off the scanning reference position P0 as a new scanning reference position P1 to read the bar code 11 of a second cassette. At the time of reading the bar code 11 of a third cassette, the cassette auto-changer sets a position -3mm off the scanning reference position, which is obtained by averaging the position -8mm off the scanning reference position and the position +2mm off the scanning reference position where the bar code 11 of the second cassette is read, as a new scanning reference position to read the bar code 11 of a third cassette.
