While periphery or peripheries of workpiece(s) W lifted in floating fashion by simultaneous suction and expulsion of gas(es) between pair(s) of first and second, or upper and lower, transport stages 14, 15 is/are retained by plurality of elevator pins 16, respective transport stage(s) is/are inverted vertically and workpiece(s) is/are transferred from upper first transport stage(s) to lower second transport stage(s) such that workpiece(s) W is/are lifted in floating fashion thereabove by simultaneous suction and expulsion of gas(es) in accompaniment to lowering of respective elevator pin(s) at said first transport stage(s).

There is presented a light emitting device, having plural light emitting elements disposed on a substrate, in which a protection element, such as a zener diode, can be disposed at an appropriate position. The light emitting device includes: a substrate; a light emitting section having plural light emitting elements disposed in a mounting area on the substrate; a positive electrode and negative electrode each having a pad section and wiring section to apply voltage to the light emitting section through the wiring sections; a protection element disposed at one of the positive electrode and negative electrode and electrically connected with the other one electrode; and a light reflecting resin formed on the substrate such as to cover at least the wiring sections and the protection element, wherein the wiring sections are formed along the periphery of the mounting area such that one end portions thereof are adjacent to each other.

A method automatically detects errors in a container inventory database associated with a container inventory tracking system of a container storage facility. A processor in the inventory tracking system performs a method that: obtains a first data record, identifies an event (e.g., pickup, drop-off, or movement) associated with the first record, provides a list of error types based on the identified event, and determines whether a data error has occurred through a checking process. In each of the checking steps, the processor selects an error type from the list of error types, determines a search criterion based on the selected error type and the first data record, queries the database using the search criterion, compares query results with the first data record to detect data conflicts between them, and upon the detection of the data conflicts, reports that a data error of the selected error type has been detected.

A lock-up clutch control device controls a lock-up clutch (6) provided in a torque converter (5) which is mounted between the engine (3) and transmission (4) provided in a vehicle. The lock-up clutch control device switches the state of the torque converter (5) between a converter state and a lock-up state by controlling a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a sensor (13, 19) for detecting a rise of a vehicle speed; a differential pressure generator (7, 8) which generates the differential pressure supplied to the lock-up clutch; and a controller (1). The controller is programmed to command the differential pressure generator (7, 8) to lock the lock-up clutch (6) when the vehicle speed exceeds a predetermined low vehicle speed (V1), after the vehicle is started; subsequently monitor the rise of the vehicle speed; and command the differential pressure generator (7, 8) to unlock the lock-up clutch when the monitored rise of the vehicle speed is lower than a preset value (Vss/αs).

A steam engine increases efficiency and prevents corrosion, abrasion, and the like in a part receiving steam pressure. A heater and a cooler are provided on one side of a U-shaped fluid container, and a piston for output is provided on its other side. The heater heats working fluid to vaporize the fluid. The expansion pressure of steam of the working fluid depresses a fluid level in a first vertical pipe. The liquid component of the working fluid flows from the first vertical pipe into a second vertical pipe, thereby applying pressure to the piston in an upward direction. Then, the liquid component of the working fluid functions as a liquid piston directly receiving the expansion pressure of the steam, so that it is possible to prevent the occurrence of corrosion, abrasion and the like in the part receiving steam pressure.
