Title: Overdischarge detecting device for battery on unmanned carriage
Inventor: MURATA MASANAO
IPC: G01R31/36
Filed: 1990-03-29
Abstract: PURPOSE:To detect overdischarge by providing voltage detecting means to respective minimum units of plural cells constituting the battery and detecting one of the voltage detecting means dropping below a specific voltage. CONSTITUTION:The respective cells 2a1 - 2an which constitute the battery 1 are provided with (n) voltage detectors 4a1 - 4an so as to detect their terminal voltages and a detection output '1' is generated when the voltage of one cell drops below the specific voltage.

Title: Producing device of magnetic recording medium and its production
Inventor: SHIGA AKIRA
IPC: G11B5/84
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To increase the bonding degree between a carbon thin film and a lubricating film and to maintain a long-term lubricating effect by disposing an ultrasonic atomizer in a plasma reaction tube and applying a lubricant on a carbon film. SOLUTION: A source web 2 is produced by forming a Co metal magnetic film on the surface of a polyethylene terephthalate base body and forming an Al-Cu back coating film on the back surface. In a vacuum chamber, plasma reaction tubes 5, 10 are disposed facing the magnetic film on the base body, and microwaves are supplied from microwave generators 7, 12 through microwave conducting tubes 6, 11 to excite plasma. Thereby, a diamond-like carbon film is formed on the magnetic film. Further, an ultrasonic atomizer 14 is attached adjacent to the plasma tube to spray a lubricant oil through a supply nozzle 9. Thereby, a lubricant film is continuously formed on the carbon thin film.  Since the lubricant film is applied by plasma CVD just after the carbon thin film is formed, a high bonding degree between the carbon thin film and the lubricant film can be obtd. and the lubricant effect can be maintained for a long term.

Abstract: PURPOSE:To form small fluid passages at low cost by embedding an element which can be etched by a specified etching means and etching the element. CONSTITUTION:An upper cover 26 made of titanium is prepared (a). A photo- resist 30 is applied on the cover 26 and exposure and development are conducted to form a desired pattern (b).
