Abstract: A cancer cell detection method that makes it possible to perform imaging of cells in a living state and a dual detection method for cancer cells in which the aforementioned method is combined with a pre-existing dyeing method for cytodiagnosis. The method uses living body-derived cells and includes: incubating living cells included in a sample taken from a person together with a fluorescently-labeled L-glucose derivative and detecting the fluorescently-labeled L-glucose derivative that is taken up into the cells; and detecting fluorescence emitted by the L-glucose derivative that is present within the cells while the cells are attached to a thin glass or plastic plate. Also provided is a dual detection method for cancer cells in which the cancer cell detection method that uses living body-derived cells is combined with a dyeing method using cells that are fixed using an alcohol or the like.

Abstract: The purpose of the present invention is to provide a novel cancer cell detection method that uses living body-derived cells and that can be used even in cytodiagnosis.

Abstract: A self scanning light-emitting array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element in a minimal conducting state influences the next light-emitting element so that its threshold level is changed. When each element is driven by a common clock pulse, the change in threshold level is shifted in the longitudinal direction, so that a minimal conducting state is transferred in a clock period of the clock pulse.

Abstract: A self-scanning light-emitting element array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element which is turned on influences a light-emitting element to be turned on next so that its threshold level is changed. When each element is clock-driven by a common drive pulse, the change in threshold level is shifted in the array direction, so that a turn-on operation is transferred in a clock period of the drive pulse.

Abstract: A self-scanning, light-emitting device comprises an array of cells or blocks each having a self-scanning transfer element and a light-emitting element. Turn-on state of the transfer element is transferred to the subsequent transfer element in synchronism with clock pulses. Each light-emitting element is connected to the corresponding transfer element so as to emit light upon supplying current under an ON state of the transfer element. The light-emitting array generates a light image in accordance with a light emission current.
