Filed: 1995-03-24
Abstract: PURPOSE: To raise a temp. till a catalytic activation temp. in a short time with low power consumption by making a thickness of a corrugated foil less than that of a flat foil so that a heat generation per volume of a heat releasing part may becomes large. CONSTITUTION: In an electrically heated carrier 2 obtained by arranging many brazing foils 8a and 8b between the corrugated foil 3 and the flat foil 4 and winding them cylindrically at a central electrode 5, the thickness of the corrugated foil 3 is made less than that of the flat foil 4 so that the heat generation per volume of the heat releasing part (hp) may becomes large among each element constituting an electricity conductive passage and a joining of the corrugated foil 3 and the flat foil 4 is executed partially. In this way, the heat generation per volume of the heat releasing part (hp) is enlarged without increasing the power consumption as a whole. Therefore, temp. rising rate of the heat releasing part (hp) is increased and the carrier is raised to the catalytic activation temp. in a short time.

Filed: 1994-04-05
Abstract: PURPOSE:To judge the progress and the life of sputtering by detecting the film of thickness of sputtered particles deposited on a measuring part of a device in a unit time and calculating scattered quantity of the sputtered particles. CONSTITUTION:A shutter 35 that covers a film thickness monitor 32 and 42 opens only for a unit time. In the unit time during which shutter opens, the sputtered particles are deposited on a crystal and resonant frequency of the crystal changes. A computer calculates with an integrated controller 34 the film thickness growth rate in the unit time. As the sputtering is continued, a range on which sputtered particles are scattered becomes narrower and the film thickness growth rate at the film thickness monitor 32 and 42 is decreased. The life of a target 14 is judged to be ended l when the film thickness growth rate reaches a certain value.

Title: Color cathode-ray tube
Inventor: KOBAYASHI HIROO
IPC: H01J29/89
Filed: 1981-04-30
Abstract: PURPOSE:To obtain a color cathode-ray tube, which provides a screen having appropriate color and can be easily seen, without deteriorating the contrast increasing effect by making a material for a filter plate to be added with Nd2O3 and a small amount of at least one of Cr2O3 and Pr2O3. CONSTITUTION:A curve (B) in the figure indicates the spectral transmittance of glass which has a thickness of 3X and contains 3.0wt% of Nd2O3. Here, when 0.003wt% to the above Nd2O3 of Cr2O3 is added to the above glass, the transmittance of the glass changes mainly in the red and the blue regions, and shows a curve (C) indicated by a broken line. As the result, in the wavelength range of 575-585nm, the difference between the light transmittances of a part of the above glass which highly absorbs light and the other part of the above glass is decreased. Therefore, the color of the above glass is not changed into raddish purple, and the color change to external light of the above glass is reduced. In addition, since the blending of Pr2O3 increases the absorbency of only the blue light component, the color of the filter plate can be adjusted close to neutral. It is preferred that the blending ratio of Pr2O3 to the above Nd2O3 is in the range of 0.1-0.5wt%.

Filed: 1990-03-19
Abstract: PURPOSE:To prevent the clogging of meshes in an opening section by installing an energizing means which presses a brush installed to a cooling fan or separate when a cooling fan starts or halts its operation. CONSTITUTION:During down time of a cooling fan 2, a brush 5 is pressed by a mesh 3 while when the cooling fan 2 is driven and rotated by a drive source 4 during the operation, the cooling fan 2 goes back against the energizing force of an energizing means 6 by the reaction of exhaust gas induced by this rotation so that the brush 5 may be separated from the mesh 3. When the cooling fan 2 comes to a halt during down time, the brush 5 is forcibly pushed to the mesh 3 by the energizing force of the energizing means 6. As a result, the mesh 3 is wiped by the brush 5, thereby cleaning the mesh 3 in automatic mode. It is, therefore, possible to prevent mesh clogging.
