Title: Light emission display driving method
Inventor: ISHIZUKA SHINICHI
IPC: H01L27/32
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To evade a light emission defect caused by the occurrence of a leakage current by applying the voltage of the direction opposite to the voltage to be applied at the light emitting time to all light emitting elements during a prescribed period. SOLUTION: A cathode line 1 imparts successively ground potential to cathode lines B1 -Bn by scanning while successively switching switches 31 -3n to a ground terminal side at a fixed time interval. For instance, when the light emitting elements E2 ,1 , E3 ,1 are light emitted, since the switches 41 , 44 -4m are switched to the ground side, the light emitting elements E1 ,1 , E4 , 1-Em , 1 aren't light emitted. Further, by applying an opposite bias voltage Vcc of the same potential as a forward directional voltage applied when the light emitting element is light emitted to other cathode lines B2 -Bn excepting the cathode line B1 while scanning, the matter that a current from a current source flows through the other cathode lines B2 -Bn is prevented, and cross talk is prevented. Thus, the voltage of the direction opposite to the voltage applied at the light emitting time is applied.

Title: Ion detector
Inventor: HIROSE HIROSHI
IPC: G01N27/62
Filed: 1980-09-16
Abstract: PURPOSE:To improve the resolution by which a solvent ion is separated and the sensitivity of a detector by scanning the ion which is incident from an ion source at the first magnetic field, removing the solvent ion, and converging a sample ion at the second magnetic field. CONSTITUTION:A sample which flows from a liquid chromatograph 1 is ionized by an ion source 2 and accelerated. Then an ion is scattered at the first magnetic field 3 of a magnetic flux density B1 by the deflection which depends on the mass charge ratio of each ion and only an solvent ion is cut off by a filter 4. Besides when only the sample ion is incident on the second magnetic field 6, it is converged into a narrow range on an ion detector 5 since the magnetic flux density B2 of the magnetic field 6 is twice as high as the magnetic flux density B1 and the direction becomes reverse. Thus the scattering distance of the ion can be increased and its convergent range can be made narrow. As a result, the resolution by which the solvent ion is separaged is increased. Moreovery, detectors, such as secondary electron multiplier, etc. can be used and its sensitivity be improved.
