The internal container is a funnel-shaped container including a cup-shaped portion and a cylindrical portion extending downward from a central part of the bottom of this cup-shaped portion.

Abstract: A variable-length packet switching system of the present invention converts variable-length packets to fixed-length packets without regard to the size of the individual variable-length packets and causes a packet switch to switch such fixed-length packets at high speed. The system realizes high-speed switching by use of, e.g., an H/W scheme. Particularly, the system is free from conversion losses when converting the variable-length packets to fixed-length packets and thereby minimizes a frequency band required of the packet switch without regard to the packet size.

Abstract: The present invention provides an insecticidal oil-based formulation, which comprises a petroleum hydrocarbon oil, a nonionic surfactant suitable for emulsifying the petroleum hydrocarbon oil, a desiccating agent and an insecticidal filamentous fungus; and a method for controlling insect pests, which comprises applying said formulation to an insect pests, a habitat of the insect pest or a plant vulnerable to the insect pest; and the like.

Abstract: In the present invention, any change of devices in possession by a user who gets on or gets off, for example, a vehicle is detected by comparing the devices detected by wireless communication at the time of getting on or getting off, thereby enabling the easy and sure prevention of any personal belongings of the passenger from being lost or left without constantly monitoring them. The property management apparatus sums up in time series the detection results by the plurality of property detection apparatuses for notifying the user the place of where the user loses the property.

The surface of lead frame at least brought into contact with molding compound is covered with roughened plating layer 10 with excessive uneven surface so that the adhesion of molding compound to the lead frame is excellent due to the function of the roughened plating layer anchoring molding compound 7 to the lead frame. Therefore, the package crack and the cut of wires do not occur.
