Abstract: In addition to storing cassettes (16a) to (16f) that store banknotes that are dispensed when money is normally dispensed, a bait money storing portion (14) is provided that stores bait money serving as an emergency banknote to be dispensed in case of an emergency. When the bait money is requested to be dispensed in case of an emergency, the bait money is forcibly transported from the bait money storing portion (14) to a banknote outlet, with the result that the bait money is dispensed quickly.

Abstract: A semiconductor wafer to be diced into individual SBDs, HEMTs or MESFETs has a substrate with a main semiconductor region and counter semiconductor region formed on its opposite surfaces. The main semiconductor region is configured to provide the desired semiconductor devices.

Abstract: An electric current detector is provided wherein loose arrangement of conductor 6 in opening 5 provides an air gap between the conductor 6 and plastic package 4 in opening 5 to prevent close contact of conductor 6 to plastic package 4. When heat and heat stress are produced in conductor 6 by a large electric current flowing through conductor 6 during measurement, air gap surely prevents heat and heat stress from traveling to Hall effect sensor 2 and plastic package 4 while a part of heat in conductor 6 is radiated into air in opening 5. Thus, the loose arrangement of conductor 6 can restrict or reduce deterioration of electric property in Hall sensor 2 and degradation of mechanical property in plastic package 4 by heat and heat stress in conductor 6. Also, the loose arrangement ensures and facilitates attachment of the detector 1 in position on a surface of a substrate, and enables to maintain conductor 6 at the same level as lead terminals 3 of the detector.

The Hall generator, control current supply circuit, and Hall voltage output circuit are all exposed at one of the pair of opposite major surfaces of the semiconductor substrate. A current-path conductor is attached to this one major surface of the substrate via insulating layers for carrying a current to be detected.

The Hall generator assembly includes a Hall generator in the form of a semiconductor chip mounted to a metal-made mounting plate, a set of leads electrically connected to the Hall generator, and a plastic encapsulation enveloping the Hall generator and parts of the leads. The Hall generator assembly and the current-path conductor assembly are combined by bonding together the encapsulation of the Hall generator assembly and the conductor holder of the current-path conductor assembly. The conductor holder and the encapsulation are shaped in interfitting relationship to each other, so that when they are united, the Hall generator is positioned to generate a Hall voltage in response to a magnetic field due to the current flowing through the current-path conductor.

Abstract: A current detector comprising a first and a second current-path detector each in the form of a sheet-metal punching having a pair of relatively broad terminal webs of rectangular shape joined together via a bridge of arcuate shape. The bridges are slender compared to the terminal webs for concentrated current flow therethrough. Various arrangements are possible for the two current-path conductors, but their bridges are invariably placed in superposition upon one another. A Hall generator is positioned between the bridges so as to be acted upon by magnetic fields created upon current flow therethrough. One of the terminal webs of the first current-path conductor is electrically connected to one terminal web of the second, in such a way that the magnetic lines of force due to current flow through the two bridges act in the same direction upon the Hall generator.

Abstract: A current detector comprising a current-path conductor in the form of a piece of sheet metal having a slit cut therein for providing a U-shaped path for the flow of current to be detected or measured. A Hall generator is held opposite the current-path conductor so as to be contained in the slit therein, as seen in a direction normal to the sheet-metal current-path conductor, for generating a Hall voltage indicative of the magnitude of the current flowing through the U-shaped current path. A magnetic overlay covers part of the current-path conductor for a higher sensitivity of current detection through enhancement of flux density acting on the Hall generator.
