    摘要: A MEA 6 having a proton conductive membrane is sandwiched by metal plates 14, 15 and they are further sandwiched by heat pressable films 20, 21. An opening 24 and an opening 18 are formed in the heat pressable film 20 and the metal plate 14, respectively so that an electrode 10 is used as the sensing electrode and exposed to atmosphere to be measured. Openings 25, 19 are formed in the heat pressable film 21 and metal plate 15, respectively so that an electrode 11 is used as the counter electrode, and water vapor is supplied to the electrode from a water pack.

    摘要: A solid electrolyte gas sensor and a method for the measurement of a concentration of a gas to be detected in a gas mixture. The sensor has (A) a screen for controlling a permeation rate of the gas, which comprises (a1) a first solid electrolytic membrane selectively permeable to ions derived from a specific gas, and (a2) a plurality of first porous conductors being present on both front and reverse surfaces of the first solid electrolytic membrane and electrically connected with each other so as to give a potential required for oxidation and reduction of the gas, and (B) a detection portion for detecting a permeation amount of ions derived from the gas, which comprises (b1) a second solid electrolytic membrane, (b2) a plurality of second porous conductors, and (b3) means of electrically measuring an amount of ions derived from the gas which permeates the second solid electrolytic membrane. The amount of ions which permeate the first solid electrolytic membrane of the above screen (A) per unit time is smaller than an amount of ions which permeate the second solid electrolytic membrane of the above detection portion (B) per unit time under conditions that the sensor is in operation; and all of ions which permeate the second solid electrolytic membrane of the above detection portion (B) are those which have permeated the first solid electrolytic membrane of the above screen (A).

    摘要: A method for warm forging a cup-shaped piece is disclosed. In warm forging a blank is heated between 400.degree. and 800.degree. C. and is inserted within a die having a cross sectional area substantially larger than that of the blank. The ends of the blank are clamped between a recess in the die and a recess in an upsetting punch and the upsetting punch compresses the blank until its sides become sufficiently bulged to almost touch, or touch, the sides of the die. The upsetting punch is then removed and a backward extruding punch is press fitted into the bulged blank and the blank is extruded to form a cup. The extrusion punch is lubricated and cooled by lubricant and coolant applicators at a position remote from the die so that the blank is not prematurely cooled by the coolant.
