Title: Analyzer for copper etching liquid
Inventor: SASAKI NORIHARU
IPC: G01N27/416
Filed: 1985-10-28
Abstract: PURPOSE:To detect the concn. of cuprous and cupric ions in an etching liquid simply and accurately with one measuring device, by oxidizing the cuprous ions to the cupric ions in the etching liquid to measure the cupric ions increased. CONSTITUTION:First, an etching liquid is run to a feed tube 1 and branched off into feed tubes 1a and 1b. Then, while the liquid flows into a first measuring cell 4b from the tube 1b and drains from a discharge tube 2b, a cupric ion electrode 3b gives the potential corresponding to the concn. of the cupric ions. A potential difference between the potential and a reference electrode 5 is detected with an ion meter 6a to display the concn. of the cupric ions. On the other hand, the etching liquid run to the tube 1a is fed with an oxidation agent from a pump 7 to increase the concn. of the cupric ions. The liquid flows into a second measuring cell 4a where it gets in contact with the cupric ion electrode 3a so that the electrode 3a will turn to the potential corresponding to the concn. of the cupric ions. A potential difference between the electrodes 3a and 3b is detected with an ionmeter 6b to measure the concn. of the cuprous ions and the concn. is displayed on the meter 6b.

Title: Method and device for sequential demodulation
Inventor: MUTO HIROSHI
IPC: G11B20/18
Filed: 1990-09-13
Abstract: PURPOSE:To improve reliability by judging to which state out of the states taken by N samples a reproduced signal is nearest considering the regularity and condition of the reproduced signal, etc., performing data synthesis based on state information, and outputting demodulated data. CONSTITUTION:When a reproduced waveform is shown in Figure (b), a sequential demodulator samples every three reproduced waveforms at an interval equivalent to the data cycle of recorded data, and state decision is performed by overlapping the three samples inputted to a state decision/data synthesis circuit 14 sample by sample in Figure (c). When a reference value Valpha is set at 0.4, the circuit 14 outputs the demodulated data in Figure (d) out of the states A, H, E,..., and data shown in oblique line is not outputted since it is overlapped data. Thereby, demodulation can be performed even when the amplitude of a part (#) in accordance with 0 of the recording data in Figure (b) is larger than that of a part (*) in accordance with 1 of the recorded data, and the demodulated data conformed to the recorded data in Figure (e) can be outputted. In such a way, correspondence such as the demodulation, rerun, etc., can be performed even when it is a deteriorated signal and a demodulation error occurs, which improves the reliability.

Title: Photographic film and packing member
Inventor: YAMAGISHI HIROAKI
IPC: G03C3/00
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce a possibility of scattering of a photographic film, a memo and a cartridge and to appropriately leave the necessary memo by packing the photographic film in a member with a recorded individual identification code and a space for a memo so that the film can be taken out and packed again. SOLUTION: A piece of paper with an individual identification code 3 and a memo column 4 is stuck to the periphery of a protective case 2 of a cartridge. A film-contg. cartridge with the same individual identification code 3 is housed in the protective case 2. It is not necessary to display all the figures of the individual identification code 3 because the purpose is temporary film identification. In other way, the protective case 2 is formed with light-colored plastic, the surface of the case 2 is roughened to enable the entry of letters and the individual identification code 3 is directly printed on the surface of the case 2. Since the packing material coexists always with the film, a possibility of scattering of the memo and the cartridge is reduced.
