Patent JP-H05325002-A (JP)
Title: Automatic vending machine
Inventor: GONDA YUTAKA
IPC: G07F9/02
Filed: 1992-05-25
Abstract: PURPOSE:To reduce the power consumption and never miss a chance of vending an article by turning off the whole illumination unless there is a passerby. CONSTITUTION:A passerby detecting means 1 is equipped with a pyroelectric element 11 as an infrared detecting element which utilizes pyroelectric effect, and this element 11 reacts as surface charges change in response to temperature variation due to the incidence of infrared rays. Consequently, a control part 12 supplies a base current to a transistor(TR) 13 and a relay 15 is driven. The pyroelectric element 11 is a differential type detecting element, so the element does not react to the stable incidence of infrared rays, but reacts to only varying incidence. Therefore, if a passerby appears in front of the passerby detecting means 1, infrared rays emitted by the living body are photodetected by the pyroelectric element 11, whose infrared-ray level remarkably increases from a usual level; and a current matching the increase speed flows to the coil 51 of the relay 5 and a switch 52 is turned on to apply the voltage of a power source to a fluorescent lamp 2, which illuminates.

Abstract: PURPOSE:To obtain high-precision fine formation, by forming one or two or more layers of acceleration/lens electrodes with insulating layers being interposed and then unifying them with a surface conduction-type electron-emission source. CONSTITUTION:An electrode-material layer 17 made of Au, Al, or the like, an insulating layer 18 made of Al2O3 or the like, and an electrode-material layer 19 are piled in order on an insulating substrate 1.

IPC: H04N1/19
Filed: 1990-06-15
Abstract: PURPOSE:To attain read of a white reference level of parts without defect by detecting the defect of the white reference level and reading the white reference level at the part without defects. CONSTITUTION:At first a reference level X0 is set to 0, a white reference level is read and a read level X1 is set to the level X0. Then an optical head is moved to read the white reference level again. The a read level X1 is compared with the reference level X0 and when an absolute value of the difference is a prescribed level DELTAA or over, it is discriminated that the white reference level at a read point has a defect and the same processing above is repeated. When an absolute value of the difference is a prescribed level DELTAX or below, it is discriminated that the white reference level at a read point is uniform and the position of the optical head is stored. The processing operation so far has only to be implemented once at the inspection after the manufacture and the capacity of the software program is almost the same. Thus, the yield is improved.
