Abstract: An alcohol metabolism enhancer is made from safe plant extracts and an alcoholic beverage and causes a reduced sick feeling and hangover from drinking alcohol without causing hemolysis using safe materials derived from plants. The alcohol metabolism enhancer and the alcoholic beverage include proanthocyanidins, such as pine bark extracts.

Abstract: A composition comprising: a flavan compound that is at least one of a proanthocyanidin and catechins; a protein degradation peptide having an average molecular weight of less than 7,000; and a peptide or protein having an average molecular weight of not less than 7,000. The composition does not impair effects of the flavan compound to the body. Furthermore, when the composition is formulated in a liquid preparation, neither coagulation-precipitation attributable to the nature of the flavan compound, nor coagulation-precipitation with the high molecular weight peptide or protein which is attributable to the protein-constricting property of the flavan compound is caused.

Abstract: In a moving object tracking system, on-board equipment and equipment disposed in a management center are connected to each other by way of a communication network. The equipment disposed in the management center receives current position information about the current position of a moving object from the on-board equipment and keeps track of the moving object. The on-board equipment has a plurality of communication units for communicating with the equipment disposed in the management center in different manners, and a communication switching unit for selecting an optimum communication unit from among the plurality of communication units based on the current position information when detecting a theft of the moving object.

Abstract: A flow control valve includes a cylinder in which an inflow port, an outflow port and a return port are formed. A spiral choke is formed between the inflow and outflow ports. A working oil introduced from the inflow port into the cylinder flows out from the outflow port through the spiral choke. An actuating valve is arranged in the cylinder so as to open and close the return port in accordance with a difference in pressure between the inflow and outflow port sides of the spiral choke. When the pressure difference exceeds a predetermined value, the actuating valve opens the return port so that a part of the working oil introduced into the cylinder is returned to the inflow side of the flow control valve.
