Title: Nonaqueous secondary battery and manufacture therefor
Inventor: TOMIYAMA HIDEKI
IPC: H01M4/134
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To further improve a charge and discharge cycle by setting at least a two- stage charging treatment process and at least two times of a preservation treatment process after filling and sealing a nonaqueous electrolyte. SOLUTION: Charging treatment is implemented at least twice at an aging process, incluidng charging and discharging treatment to be made after sealing a battery. Also, open circuit voltage at the first charging treatment is taken at a value between 1.5 V and 3.8 V. In this case, the battery after being filled with an electrolyte and a caulked is charged, or charged and discharged as a method for keeping the open circuit voltage within a preferred range. The battery is then stored over a period of 1 to 30 days at temperature between 20 deg.C and 70 deg.C over a period from the first charging process to the second charging process. Thereafter, the second charging treatment is implemented at an open circuit voltage between 3.8 V and 4.3 V and, then, the battery is stored over a period of 1 to 30 days at a temperature between 40 deg.C and 80 deg.C.  For the proper attainment of the open circuit voltage at the charging process, the battery is preferably charged up to the prescribed level with a constant current and a constant voltage charging process implemented, thereby keeping a difference of 0.1 V or less between the charge voltage and the open circuit voltage.

Title: Method for monitoring in-service of optical amplification relay transmission line
Inventor: TSUNODA MASATOYO
IPC: H04B10/07
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To detect a loss change position by measuring a reception level of a back- scattered light, corresponding to an elapsed time after transmission of an monitoring optical pulse, so as to locate a content of an abnormal loss and its produced position on an optical amplification relay transmission line. SOLUTION: A monitoring optical pulse, sent from an optical transmission section 1, is combined with an optical communication signal by a combiner 2, and the combined signal is sent to an optical amplification relay transmission line which is a monitor object. An optical repeater 4, incorporating an optical fiber amplifier 3, is placed in the optical amplification relay transmission line to compensate a loss received by the optical signal at each relay block. A back-scattered light generated in the optical amplification relay transmission line by the monitoring optical pulse is led to an opposite line. The back-scattered light and the optical communication signal propagated through the opposite line have different wavelength bands, so that they are separated by an optical filter 7.  The separated back-scattered light is given to an optical reception section 6, where the strength of the back-scattered light is measured. Thus, the position of the transmission line at which a loss abnormality is in existence is located, based on an elapsed time after the monitoring optical pulse is transmitted.

Filed: 1988-02-10
Abstract: PURPOSE:To eliminate an output of an undesired signal charge during the vertical scanning period by transferring the undesired signal charge at electronic shutter operation to a drain provided to the opposite side to the vertical transfer section of a horizontal transfer channel, discharging the charge to the substrate and discharging the undesired signal charge left in the horizontal transfer channel to an output section. CONSTITUTION:In case of discharging an undesired signal charge, the electric charge not handled by a horizontal transfer section 13 flows to the drain 7 through an overflow gate 6 and is discharged to an n-type substrate 9 receiving a positive voltage from the drain 7. Moreover, a little signal charge left in the horizontal transfer section is discharged to the output section to discharge the undesired signal charge completely. Thus, the undesired signal charge left in the operation of electronic shutter outputted during the vertical scanning period is avoided.
