Abstract: PURPOSE: To prevent an error in detected position owing to the density of color of an aiming mark and the change of printing speed and to improve the detection precision of the aiming mark by setting reference voltage to be a value proportional to the peak value of the electric signal of reflected light so as to detect it and comparing the electric signal waveform of reflected light with a reference voltage. CONSTITUTION: A printing aiming mark printed on a printing material is read out by an optical means. The peak of a signal output detected by a mark detection circuit 1 transmitting a mark signal which is read out as mark information is taken out. The voltage of a prescribed magnifying factor, which is lower than the peak value that is taken out, is stored in a storage part 4 as reference voltage 3. A comparison part 5 compares the reference voltage 3 of the storage part 4 with the signal output detected in the mark detection circuit 1, and the intersecting point is outputted as the position signal of the mark. The peak value of the electric signal waveform generated in the received light element circuit of the reflected light by the density of the color of the mark differs but the change rate with time is the same.  The position (time) error is dissolved when the value proportional to the peak value is set to be the reference value.

Filed: 1990-10-18
Abstract: PURPOSE:To enable measurement of material changeable structurally by heat by a method wherein a release of photoelectrons generated from a sample irradiated with a fixed wavelength of light is detected to determine a matter adsorbing on the surface of the sample and the wavelength of irradiation light is changed to perform a qualitative measurement of the adsorption matter. CONSTITUTION:A measuring sample 2 is placed in a dry air to be irradiated with light 8 with a wavelength selectable and photoelectrons 4 generated come into the air to turn to oxygen ions in reaction with oxygen molecules. The oxygen ions are measured with a detector 1 and the number of the photoelectrons per unit time is outputted. When a matter 7 exists adsorbing on the sample 2, the light 8 is absorbed in a certain wavelength area by the adsorption matter 7. Moreover, electrons 4 generated inside the sample 2 are absorbed by the absorption matter 7 to allow the conversion of an absorption value of the absorption matter 7 from a decrement of a release of the electrons 4 outside the sample 2. The wavelength of the light 8 is changed to allow a quantitative measurement of the absorption matter 7. This enables quantitative and qualitative measurement of the absorption matter 7 even for material changeable structurally by heat.
