Title: Pachinko machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko machine which can detect the case when a ball entered within a big prize-winning port blocks the port and is not discharged normally from the large prize-winning port and which can easily judge its cause. SOLUTION: When the number of prize-winning ball detected by prize-winning detectors 25a, 25b and the number of discharged balls detected by residual ball detectors 33a, 33b are compared with each other. When the number of the prize-wining balls and the number of the discharged balls are not coincident with each other at the point of the time when a prescribed period passes after a variable prize-winning ball device 20 comes into a first state (open state), this unequal comparison is judged to be abnormal and then the number of errors between the number of prize-winning balls and the number of the discharged balls is displayed in a recognizable state.  Since in the case of noncoincidence of the prize-winning balls and the number of the discharged balls, the noncoincidence is detected as abnormality and the number of errors between both of the numbers is repeated, the generation of abnormality can be detected and it is easy to judge whether the cause is clogging with balls or abnormality is generated excepting for it.

Title: Quantum interference effect element
Inventor: FUCHIGAMI NOBUTAKA
IPC: H01L29/80
Filed: 1989-02-10
Abstract: PURPOSE:To provide channels of uniform quality and to simplify the process of producing quantum interference effect elements by removing a part of a channel forming layer to provide a non-channel region in one channel. CONSTITUTION:In order to decrease contact resistance of source and drain 4, ions are implanted into the source and drain 4 so that an undoped GaAs 1 directly under the source and drain 4 is converted into N<+> type GaAs 3. A channel width is sufficiently small so that electrons occupy the lowest sub-band only. A hole 9 is opened by an FIB(focused ion beam) for example at the center of the undoped GaAs channel 1 which conducts electrons ballistically, so that the electrodes are shunted before reaching the hole 9 and then joined together again to be observed. Since the channel width is sufficiently small, the electrons can be conducted along the heterojunction defined with the N-type AlGaAs 2 having a low potential with their monochromaticity being kept. In this manner, a quantum interference effect element of high quality can be produced easily.

Filed: 1989-02-09
Abstract: PURPOSE:To form a polycrystalline silicon film which does not show the deterioration of characteristics such as an electron mobility by a method wherein the polycrystalline Si film is made to contain fluorine. CONSTITUTION:A polycrystalline Si film is made to contain fluorine. A molecular coupling between Si and hydrogen in a polycrystal line Si film is easily cut off and the hydrogen breaks away from the film easily. On the other hand, a molecular coupling between Si and fluorine in a polycrystalline Si film is firm and the fluorine hardly breaks away from the film. With this constitution, if the polycrystalline Si film subjected to a fluorine treatment is applied to a thin film transistor, the switching speed of the transistor can be improved and, at the same time, the deterioration of switching speed characteristics can be avoided.
