Abstract: This apparatus includes an external tank in which ink is stored outside a circulation path, a branch pipe connecting a branch point on the circulation path and the external tank, an external pump that delivers ink from the external tank to the circulation path, a switch valve, and a temperature sensor that detects a temperature of ink in the circulation path. The switch valve can switch between a state in which the external tank communicates with the branch point via the external pump and the branch pipe and a state in which the external tank communicates with the branch point not via the external pump, but via the bypass pipe. When a result of detection by the temperature sensor is out of a predetermined range, a control unit can deliver ink in the circulation path to the external tank via the bypass pipe.

Abstract: An inkjet printing apparatus includes an ejection head, an ink supplier, a heater unit, an ejection amount calculator, and a first heater controller. The ejection head includes a plurality of the nozzles for ejecting ink to a surface of a printing base material. The ink supplier supplies the ink to the ejection head. The heater unit heats the ink to be supplied to the ejection head. The ejection amount calculator calculates an ejection amount of the ink to be ejected from the ejection head at a moment after the present moment on the basis of printing data indicating an image to be recorded on the printing base material. The first heater controller controls the heater unit on the basis of the ejection amount calculated by the ejection amount calculator.

Abstract: An inkjet printing apparatus includes a discharge head configured to discharge ink, a supply tank in which ink supplied to the discharge head is stored, a collecting tank in which ink collected from the discharge head is stored, a connecting pipe connecting the supply tank and the collecting tank, a circulation pump that is interposed in the connecting pipe and is configured to deliver ink from the collecting tank to the supply tank, a replenishment tank in which ink with which the supply tank is replenished is stored, a replenishment pipe connecting the replenishment tank and the connecting pipe, and a replenishment pump that is interposed in the replenishment pipe and is configured to deliver ink from the replenishment tank to the connecting pipe. A connection point of the replenishment pipe and the connecting pipe is positioned between the circulation pump and the supply tank.

Abstract: A printing apparatus for printing on printing media in a continuous business form.

Abstract: An impact absorbing member is provided below a fascia upper member (upper-face forming member) which forms an upper face of a front end portion of a vehicle. The impact absorbing member comprises a front side part which includes a front wall portion, a top wall portion, and a rear wall portion so as to have a U-shaped cross section opening downward and a flat-plate shaped rear side part which extends rearward from a lower end of the rear wall portion. A rear end portion of the rear side part is held at a radiator shroud as a vehicle-body-side member, and the rear side part is configured to slant obliquely forward and downward.

Abstract: A monoclonal antibody that does not show a crossreactivity with middle-molecular weight (MMW) adiponectin and specifically reacts with high-molecular weight (HMW) adiponectin alone is disclosed. The monoclonal antibody of the present invention can be produced by using HMW adiponectin as an antigen. According to the monoclonal antibody of the present invention, a convenient, high-accurate, and versatile reagent for analyzing HMW adiponectin can be provided.
