Title: Stabilization method for and low density standard gas obtained by the same
Inventor: ADACHI FUJIO
IPC: G01N1/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To provide the stabilization method of low density standard gas capa ble of accurately indicating the density of component gas especially at a low- density, while hardly causing density change at the time of preservation over the long period of time even in the case of containing specified component gas such as acrylonitrile. SOLUTION: After a container 1 is evacuated by a vacuum pump 3 beforehand, pure water is vaporized and introduced through a sealing material 5a into the container 1 by an injector or the like, and adsorbed by the inner wall of the container 1. Thereafter, the low density standard gas containing the fine amount of the component gas is filled in the container 1 from a container valve 2. Since the inner wall of the container 1 adsorbs the water molecules of the pure water in advance, the density is not changed by adsorbing the component gas in the standard gas by the inner wall of the container 1.

Abstract: PURPOSE:To enable a non-contact and high speed measurement with simple arithmetic unit by picking up the image of an object by the ITV camera couple installed on the same image pickup axis and by detecting the distance upto the body to be measured by using the order relation between the image pickup signals thereof. CONSTITUTION:The optical image of the body 20 to be measured is picked up as a video on the same image pickup axis respectively to an ITV camera 21 through a half mirror 25 and simultaneously to ITV camera 22 via a mirror 25 and mirror 26. Namely, the optical path length between the body 20 to be measured and camera 22 is longer by the interval d2 between mirrors 25, 26. Therefore, processing unit 27, 28 detects the video distance of the body 20 to be measured from the video signal of the camera 21, 22 with the technique of Lang's method, etc. And a processing unit 29 calculates the distance upto the body 20 to be measured by using the signal from units 27, 28.

Title: Electrostatic charging device for image forming device
Inventor: OYAMA SHOICHI
IPC: G03G15/02
Filed: 1989-07-21
Abstract: PURPOSE:To independently control individual electrostatic charging conditions for plural electrostatic charging devices which are driven by one power source by setting at least one of side plates on a moving means which can adjust a distance between a corona wire and the side plate and moving the side plate. CONSTITUTION:When the corona wire 104 is connected to one output terminal of a high voltage power source and a shielding case 101 and a photosensitive body 105 are connected to the other output terminal thereof, corona discharge generates between the corona wire 104 and the shielding case 101 and between the corona wire 104 and the photosensitive body 105. When a distance D between the corona wire 104 and the side plate 103 is changed in the case that the high voltage power source has constant-voltage characteristic, a corona discharge current which flows in the photosensitive body 105 is proportioned to the dis tance D. Therefore, the magnitude of the corona discharge current which flows in the photosensitive body 105 is controlled by adjusting the distance D. Thus, the magnitude of the corona discharge current which flows in the photosensitive body side is easily adjusted and set without controlling the output of high ten sion current.
