Title: Gas laser oscillator
Inventor: MURATA TAKAAKI
IPC: H01S3/038
Filed: 1987-09-30
Abstract: PURPOSE:To make uniform the high frequency discharge of a laser medium and prevent a decrease in laser output, by a constitution wherein the electrostatic capacity of a dielectric electrode with respect to a laser medium gradually decreases toward the downstream of a laser medium flow. CONSTITUTION:When a high frequency voltage is applied to metal electrodes 14a, 14b by a high frequency power source 10, high frequency voltage is applied to the outer hull 1a of a discharge tube 1 via an air layer 15. This in turn causes high frequency voltage to be applied to the inside of the hull 1a, that is, gas 11 in a discharge portion, to excite the gas 11 by high frequency discharging, providing laser oscillation between an output mirror and a rear mirror 8 and outputting laser via the output mirror. The thickness of the air layer 15 is adjusted by a dielectric electrode 16 consisting of the metal electrode 14a, 14b, air layer 15 and the outer hull 1a so as to make high frequency current uniform. This can keep impedance between electrodes 14a, 14b almost constant and uniform high frequency discharge by gas 11 is assured.

Title: Image forming device
Inventor: TSUJIMOTO KOJI
IPC: G03D13/00
Filed: 1989-09-22
Abstract: PURPOSE:To prevent danger from happening to a human body and to prevent raise in the cost of a device and the running cost by specifying the arrangement of a light source for exposure which exposes an image receiving paper. CONSTITUTION:The light source for exposure which exposes the image receiving paper 8 is arranged between a pressure developing device 6 which pressurizes a photosensitive and pressure sensitive paper 2 and the image receiving paper 8 and an ejection part 11 which ejects the image receiving paper 8 to the outside of an image forming device main body. Therefore, before the image receiving paper 8 is ejected to the outside of the image forming device main body, it is exposed and at least monomer on the surface part is made hard. Thus, even when a user touches the image receiving paper 8 ejected to the outside of the image forming device main body, the danger which causes rash, poisoning or the like to the skin of the user is prevented from happening. Besides, safety is secured by such simple constitution that only one light source is arranged. As the result, the raise in the cost of the device and the running cost is avoided.
