Title: Color photosensor element and discriminating method of incident ray by using said element
Inventor: UCHIYAMA AKIRA
IPC: H01L31/10
Filed: 1983-02-16
Abstract: PURPOSE:To discriminate the colors of color beams without using a color filter by discriminating incident beam wavelengths by the ratio of photoelectric conversion outputs between a case when beams to be discirminated are projected to a photoconductive section through a transparent insulating substrate and a case when beams are projected to the photoconductor section without passing through the transparent insulating substrate. CONSTITUTION:A photoconductor section 21 such as amorphous silicon is formed on a transparent insulating substrate 22, and electrode sections 23, 24 are formed on the photoconductor section 21. The conductivity of the photoconductor section 21 changes in proportional to the intensity of beams shown in the arrow (L) or (L') by the irradiation of the beams, and the irradiation of the beams can be detected as currents between the electrode sections 23 and 24 by previously applying voltage between the electrode sections 23 and 24. However, since photoconductive characteristics in the vicinity of the atmospheric surface of amorphous silicon are inferior to those in a bulk in general, the increase of conductivity as a whole is comparatively small on the irradiation of beams in the L direction of the arrow, and the large increase of conductivity is obtained as a whole on the irradiation of beams from the L' direction, thus discriminating color beams.

Title: Short pulse laser apparatus by discharge excitation
Inventor: WAKATA HITOSHI
IPC: H01S3/038
Filed: 1986-02-06
Abstract: PURPOSE:To obtain a stable laser output, by providing a high voltage pulse circuit for pre-ionization. CONSTITUTION:A high voltage pulse circuit for pre-ionization is formed. In this circuit, a switch 7 is connected between a first main electrode 2 and an auxiliary electrode 5, and an impulsive voltage is impressed between the both electrodes. As to a switch 7, a spark-gap switch of a self-firing type is used. As a potential difference exsists between the both contacts of a spark gap, pre-ionized electrons are scattered by a creeping discharge prior to a main discharge, when the operation voltage of the spark-gap switch 7 is made a little lower than the voltage generating the main discharge. A stable laser output can be obtained by adjusting the timing of pre-ionization according to the method as mentioned above.
