Filed: 1978-10-05
Abstract: PURPOSE:To restrict overflow of an electric charge while being transferred, by reducting an input charge from a source below the maximum accumulated charge under a transfer electrode lower than No.2 step. CONSTITUTION:An ion is injected into a charge accumulation region under No.1 step electrode 141, this surface potential is made to get closer to a surface potential of a barrier region 151 rather than to a surface potentials of charge accumulation regions lower than No.2 step 142, and an input charge to be set to No.1 step 141 is set to a less value than the maximum accumulation charge lower than No.2 setp 142. When a source 12 is OV and a potential of the electrode 141 is as low as 5V, a difference between a surface potential of No.1 step barrier region 151 and a potential of the source region 12 is  , and when OV of the source 12 is varied to minus side or the low level of No.1 step 141 is varied to plus side, this mechanism effectively controls such an erroneous operation that a charge is input from the source 12 jumping over No.1 step barrier 151, and since overflow of a charge being transferred is prevented, as signal charge which is less than the maximum accumulation charge under the electrode is put in so as to prevent the erroneous operation.

IPC: H01M4/88
Filed: 1986-05-28
Abstract: PURPOSE:To prevent cracks from occurring in an electrode catalyst layer, by preparing a freezed electrode catalyst layer which is formed by cooling an electrode catalyst layer to freeze a medium, and then sublimating it in a sublimation container so that the medium in the electrode catalyst layer can be removed. CONSTITUTION:A freezed electrode catalyst layer 13A, which is formed by cooling an electrode catalyst layer to freeze a medium, is prepared and then sublimated in a sublimation container 31 so that the medium in the electrode catalyst layer can be removed. That is, the freezed electrode catalyst layer 13A is heated by a heating means 32 in the sublimation container 31. While heat for sublimation is supplied, then a pressure inside the sublimation container 31 is controlled to be 0.2 mmHg or less by a vacuum source 37 so that isopropyl alcohol and water freezed in the sheet are sublimeted. Vapors 33 are condensed and removed in a condenser 34 cooled by a cooling medium 35. Hence, the mixing medium to be freezed never becomes soluble on its sublimate operation, and therefore its vaporization from a solid phase can be secured. Resultantly the electrode catalyst layer having no crack can be safely and securely manufactured.

Title: Low-frequency pulse tig welding method
Inventor: KUREISHI MASAYOSHI
IPC: B23K9/16
Filed: 1979-09-25
Abstract: PURPOSE: To decrease the drooping of beads in posture welding and prevent arc break by superposing low-frequency pulse current on direct current and further superposing middle- and high-frequency pulse currents thereon in performing welding.  
     CONSTITUTION: Pulsating current of square waves or trapezoidal waves within frequency 10Hz is superposed on direct current to make low-frequency pulse current A. Further, middle- and high-frequency pulse currents B of 50HzW50kHz are superposed on this pulse current A to make middle-, high-frequency superposition type low-frequency pulse current. By using this current, TIG welding is performed. With this method, the current A prevents overheating of molten pool and decreases the drooping of beads; in addition, the current B hardens the arc to make the directivity of the arc good, thereby preventing arc break. Thus even if the target position of the electrode deviates, the arc will not deflect and the arc is maintained in the electrode end direction.
