  • Patent number: 11498064
    Abstract: A photometric dispensing nozzle unit, a photometric dispensing apparatus, and a photometric dispensing method are for preventing an increase in apparatus scale and have a simple structure to be easily handled. A nozzle performs suction/discharge of gas through a distal end opening and can have a dispensing tip attached thereto. A light guide end portion is provided in the nozzle and can receive or irradiate light at a distal end of the nozzle. A dispensing cylinder has a cylinder having a cavity therein, a plunger that is slidable in the cavity, and a suction/discharge port that performs suction/discharge of gas. A suction/discharge flow path passes through the nozzle and communicates with the suction/discharge port and the distal end opening of the nozzle. A light guide path is optically connected to the light guide end portion through the nozzle but not through the dispensing cylinder.

  • Publication number: 20220293901
    Abstract: A roll press apparatus includes a first press roll and a second press roll. The first press roll includes a first contact part configured to contact an active material portion of a strip-shaped electrode sheet and a second contact part configured to contact an active-material absent portion of the strip-shaped electrode sheet. The second contact part has a large frictional-force generating form that causes a larger frictional force to be generated between the second contact part and the active-material absent portion of the strip-shaped electrode sheet than an imaginary frictional force which would be generated if the active-material absent portion of the strip-shaped electrode sheet were made to contact the first contact part.

  • Publication number: 20220293911
    Abstract: A roll press apparatus forms a compressed strip-shaped electrode plate by roll-pressing a strip-shaped electrode plate including an active material portion and an active material absent portion and including a tensile-force-ratio adjustment mechanism adjusting a tensile force ratio of an upstream active material absent portion tensile force applied to an upstream side and a downstream active material absent portion tensile force applied to a downstream side of an inter-roll active material absent portion held in a non-compressed state between a pair of press rolls in an active material absent portion of the strip-shaped electrode plate.

  • Patent number: 6252376
    Abstract: A plurality of battery modules are provided for each module monitoring unit. When a battery module is normal, a photo-FET of a photocoupler contained in a module monitoring unit 5 associated with the battery module is turned on. When it is abnormal, the photo-FET is turned off. Those photo-FETs, provided in association with the battery modules, are connected in series by two signal lines. A management unit detects whether the circuit including those signal lines is opened or closed, and finds an abnormal battery module on the basis of the detection.

  • Patent number: 6169385
    Abstract: Forced discharging circuits each of which is configured by connecting in series a transistor, a reverse blocking Zener diode, and a discharging resistor are connected between positive and negative output terminals of cells, respectively. In each of the Zener diodes, the Zener voltage is set to be substantially equal to the cut-off voltage of discharge of the corresponding cell. The bases of the transistors are connected to a switching control circuit. The transistor of each of the forced discharging circuits is set so as to have a larger on-duty ratio, as the cell to which the forced discharging circuit is connected is remoter from a ground line, so that the average currents flowing through the cells are equal to one another.
