Abstract: A drug tray is for containing all drugs prescribed for each patient, and includes a display unit for providing an indication of the drugs which have been placed in the tray. The display unit has a signal transmitter/receiver, drug type indicating switches, time key, reset key, etc. The drug tray eliminates the conventional need for a large shelf for collecting drugs needed for a number of patients.

Abstract: In a fuel injection pump equipped with a plunger producing preflow effect, pressurized fuel is delivered at least in the low engine speed region by driving the plunger using a region of a cam on the decreasing velocity side of its maximum velocity point. As a result, the fuel delivery rate is reduced during low-speed engine operation and increased during high-speed engine operation, providing an ideal fuel delivery rate for an indirect-injection type engine equipped with swirl chambers or auxiliary chambers.

Abstract: A zirconium alloy which has good creep strength and bending properties as well as improved corrosion resistance in nitric acid solutions of low, medium, and high concentrations and which can withstand stress corrosion cracking in highly concentrated nitric acid solutions even under a high anodic potential is disclosed. The zirconium alloy consists essentially of, by weight percent:one or both of Ti: 5.0-30% and Ta: 1.0-20%,Fe: not greater than 0.3%, Cr: not greater than 0.1%,Oxygen: 0.05-0.2%, N: not greater than 0.45%,H : not greater than 0.01%,one or more of W, V, and Mo: 0-3.0% in total, and the balance Zr and inevitable impurities.

Abstract: A method for automatically controlling the position of small objects, comprises the steps of moving the object to cause at least a portion of an optical image of the object to be imaged on a photoelectric array which is placed on an image formation plane; sequentially detecting outputs by scanning photoelectric converting elements constituting the photoelectric array; counting, in a digital fashion, the position data of the object based on the above-mentioned outputs to deliver a correction signal for moving the object to a predetermined position; moving the object to a predetermined position according to the correction signal; and checking the position of the object by detecting outputs of respective photoelectric converting elements after completion of the above-mentioned movement step and calculating the positional data of the object.
