Title: Printer
Inventor: TSUSAKA MASAKI
IPC: H04N1/41
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a printer in which a storage capacity of a memory is ensured, even when image data are stored for a long time. SOLUTION: Upon receipt of print data in the storage print mode in a printer 10, when an idle capacity of a storage unit 16 is more than a designated value, the compressed data are accumulated after a compression process. When there are data which have been accumulated in the storage unit 16 for a specified time and whose compression rate is less than a maximum compression rate, the data are compressed again at a compression rate which is increased by one level and the resulting data are replaced with the image data in the storage unit 16. When a maximum compression rate is exceeded at a compression rate increased by one level, it is displayed as an error on a display input section 18.  When data capable of being compressed again do not exist in the storage unit 16 and data are received and being stored at present, the data being received are converted into image data, which are compressed at a compression rate higher by one level, and the compressed data are stored in the storage unit 16.

IPC: H01M8/02
Filed: 1991-12-27
Abstract: PURPOSE:To provide smallness in internal resistance and excellence in corrosion resistance and further to improve hydrogen adsorbing power by coating a surface of a collector with a metal excellent in conductivity and corrosion resistance. CONSTITUTION:A fuel cell has an electrolyte film, positive electrode and a negative electrode 20 in both sides of the film, collector 30 in the outside of the electrode 20 and a collector terminal 40 brought into contact with this collector as a single cell. Here, a surface of the collector 3 consisting of porous carbon sintered material or the like is coated with a metal of platinum, gold, iridium, etc., excellent in conductivity and corrosion resistance to about 0.05 to 2mum by a spattering method or the like. In this way, a sum of contact resistances between the collector 30 and the terminal 40 and between the collector and an electrode and resistance of the collector 30 itself is reduced to about 1/2. Since a metal is advanced into an interface of the collector and a catalytic layer, also hydrogen adsorbing power is improved.

IPC: H04B10/00
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To easily detect the signal loss even if an optical signal consists of plural signals of different wavelengths by making clear the signal loss of a transmission line, when the signal sent to the transmission line is cut and switching the transmission line to a protective transmission line. SOLUTION: A signal loss detector 205 detects whether the signals are consecutively received via a service transmission line 26 (or a protective transmission line 31). If the signals are not received consecutively, the detector 205 issues a command to have a control processor 250 to switch an optical switch 210 switch to transmit the signals which are consecutively received by a transmission line 227 via the line 31 to a transmission line 48. Then the switch 230 is actuated to have the signals interrupt, which are supplied to an output side service transmission line 25. A light protection switch device 50 placed at one of both ends of the line 25 detects the signal loss due to the interrupt of signals, and the line 25 is switched to a protective transmission line 30.
