Abstract: PROBLEM TO BE SOLVED: To remove heavy metal by a method wherein the mirror surface finishing of a glassy carbon plasma etching electrode is carried out by the use of a polishing solution which contains silicon oxide particles, and the plasma etching electrode is cleaned with hydrofluoric acid or a mixed acid that contains hydrofluoric acid. SOLUTION: The surface of a glass plasma etching electrode exposed to plasma is subjected to mirror surface finishing so as to be as high in surface smoothness as prescribed. A polishing solution used for mirror surface finishing of the plasma etching electrode contains 0 to 50 wt.% SiO2 particles which are preferably about 5 to 100 nm in grain diameter. Thereafter, the etching electrode is cleaned with a hydrofluoric acid or a mixed acid that contains a hydrofluoric acid. At this point, it is preferable that 10 to 26 wt.% hydrofluoric acid is used. It is preferable that the etching electrode is rinsed with pure water after it is cleaned with hydrofluoric acid. It is preferable that a cleaning operation is carried out through a manner where the electrode is dipped into a cleaning solution and subjected to ultrasonic cleaning.

Title: Pump loop diagnostic device
Inventor: MATSUI YUJI
IPC: G01M99/00
Filed: 1992-12-15
Abstract: PURPOSE:To detect abnormality occurring in a pump loop with high sensitivity and surely, not effected by external factors, by calculating expected temperature of the liquid circulating in the loop based upon energy difference between the energy occurring inside the loop and one released into the outside air, and comparing it with actual temperature. CONSTITUTION:The water flows from a water drum, through a valve 1, into a purification system loop 3, and then, through a valve 2, introduced into a reactor core again. In the loop 3, the water is circulated by a pump 4. Flow rate signal 22, measured by a flow rate measuring device 15, is converted into generated heat quantity 23 by an integration calculation device 18. Based upon the generated heat quantity 23 and outside air temperature signal 24 measured by an outside air temperature measuring device 16, an expected temperature calculating device 19 calculates expected temperature 25. The expected temperature 25 and actual temperature 26 measured by a water temperature measuring device 17 are recursion-analysed with a regression analyser 20. As a result of analysis with the analyzer 20, if the regression coefficient significantly gets out of the range pre-set by the regression coefficient, it is diagnosed that abnormality took place in the loop.

Title: Developing device
Inventor: NAGASHIMA TAKASHI
IPC: G03G15/08
Filed: 1990-11-28
Abstract: PURPOSE:To uniformly mix toner in developer and to accurately and stably control toner concentration by forming the outside diameter of a stirring member at a part where the developer is hard to be supplied by a guiding means larger than that at other part on a stirring roller. CONSTITUTION:A spiral plate 23a is formed on the outer peripheral part of the stirring roller 23, and the outside diameter of the spiral plate 23a at the part where the developer is easily supplied by flow straightening vanes 27 is formed to be small and the outside diameter of the spiral plate 23a at the part, where the developer is hard to be supplied, between the vanes 27 is formed to be large. Therefore, when the developer is supplied from the guiding means to the stirring roller 23, the surface of the part where the developer is accumulated on the roller 23 is made even and the toner is prevented from being accumulated even in the case that the toner is supplied from the above. Thus, the toner concentration is uniformized and the toner concentration is accurately controlled.

Title: Semiconductor device
Inventor: ITO HIROYASU
IPC: H01L21/336
Filed: 1992-11-19
Abstract: PURPOSE:To improve the service life of a semiconductor device by forming contact holes in corresponding to an increase in degree of integration. CONSTITUTION:In contact holes 110 formed through the insulating layer 106 of a CVD oxide film coating semiconductor elements, polycrystalline silicon films 107, high-melting point metallic composite films 108 of a barrier metal, and aluminum-alloy electrodes 109 are successively formed on their bottoms. Each film 108 is composed of a TiN upper layer and Ti lower layer. The silicon used in the films 107 is usually used for forming substrates and does not cause any abnormal diffusion. In addition, the silicon in the upper-layer sections of the films 107 forms a silicide and the volume change of the silicon only occurs within the upper layer sections and does not affect diffusion areas 105. Since the Ti silicide has a resistivity value of about 17muOMEGA.cm which is lower than that (about 45muOMEGA.cm) of the Ti metal, the film 107 can surely obtain conductivity and can offset a resistance rise due to the narrowed part of wiring at a step part on the insulating layer.

Title: Camera capable of trimming-photographing
Inventor: MATSUI TORU
IPC: G03B17/24
Filed: 1990-11-29
Abstract: PURPOSE:To automatically set trimming magnification and to optimize trimming- photographing by deciding the trimming magnification so that plural range- finding points may be included in the case that plural range-finding points are set and nearly equivalent range-finding values can be obtained. CONSTITUTION:In the case of a trimming photographing mode, the light quantities of three light emitting elements 1c-1e are made equivalent to the light quantity of all the light emitting elements at an ordinary time, and also the three light emitting elements are arranged so as to measure the distance to the central part of an object field, then, the light quantity for measuring the distance to the central part is increased, so that the farther distance can be measured. That means, each point (a)-(g) in a screen frame 9 for showing the range-finding position in a photographing screen corresponds to LEDs 1a-1g, and in the case that plural nearly equivalent values are outputted from each range-finding point, the magnification for the trimming photographing is automatically set so as to include all the points where the values are outputted. Then, the range-finding effects in plural points can be effectively used. Thus, the automatic setting of the trimming magnification by pseudo zooming can be obtained based on the range-finding value in multiple range-finding.

Title: Image forming device
Inventor: ASAMI JIYUNYA
IPC: B41J29/02
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent an output image from banding caused by the vibration of a motor and the like and to provide an excellent-quality recorded image by constituting a scanning optical device itself as a different beam and assembling it between two side plates. SOLUTION: A main body frame 7 is constituted so as to be largely divided into three parts of two parallel sides plates 7a, the beam 7c laid between two plates 7a and the positioning part for an optical box 7b and integrally formed of resin. By fitting an optical box 6 to the frame 7 as the second beam being in parallel with the beam 7c, the high-rigidity box 6 becomes the structure material of the frame 7 and the frame 7 is provided with high rigidity with respect to the vibration in a direction shown by an arrow A. That means, the deformation of the box 6 is suppressed also at a point Q by constituting the box 6 itself as the second beam. Thus, since load imposed on the frame 3 caused by the vibration is dispersed to a point P and the point Q, the deformation of the frame 7 is reduced.
