IPC: G03B27/02
Filed: 1986-08-06
Abstract: PURPOSE:To prevent energy from being wasted due to excessive charge to a main capacitor, by providing a control circuit for executing a control so that the charge is completed, when the charge to the main capacitor has reached a selected level, and a means for displaying a fact that the charge is completed and light can be emitted. CONSTITUTION:After a charge control circuit 24 has become an operating state by turning on a power source switch 26. When one of selecting switches 21 corresponding to a kind and an image density of an original is depressed, its condition is held in the charge control circuit 24, and also, charge to a main capacitor 27 is started. When the charge reaches a charge level which has been held, the charge is completed, a charge completion display lamp 23 is lighted, and it is displayed to an operator that light can be emitted. When level-down of energy occurs due to self-discharge of the main capacitor, re- charge is executed by that portion, and a prescribed level is maintained until a light emission switch 28 is depressed, when the display is confirmed, and the operator depresses the light emission switch 28, a high voltage trigger voltage is generated in a trigger circuit 29, and a flash lamp 7 emits light by the light quantity corresponding to a charge level of the main capacitor 27.

Title: Polishing solution and polishing method
Inventor: SHIBA KATSUIKU
IPC: B24B37/00
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To fix the contact area between polishing particles and a film to be polished and, at the same time, to fix the polishing speed by improving the dispersibility of the polishing particles at the time of performing CMP, by adding a prescribed surface active agent to a polishing solution prepared by dispersing the polishing particles in pure water. SOLUTION: A polishing solution is prepared by dispersing polishing particles in pure water and, at the same time, adding a surface active agent to the water. The surface active agent can be polyvinyl pyrrolidone, cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose, or ethylene glycol alginate. When the surface active agent is added to the polishing solution, the dispersibility of the polishing particles is improved at the time of performing CMP. In other words, when the polishing particles advance in such a way that the particles come into contact with the surface of a film to be polished and shave off the surface, almost all polishing particles are dispersed in the state of primary particles.  As the CMP progresses, therefore, the contact area between the polishing particles and the film to be polished is fixed at a a larger value and, at the same time, the polishing speed is also fixed.
