Inventor: SUGIMURA TOSHIKAZU
IPC: H01J37/30
Filed: 1994-07-22
Abstract: PURPOSE:To stably radiate an electron beam for a long time by impregnating an ion impact resisting high melting point heat resisting material with an electron emitting material having a relatively small work function and a high electron emitting current density. CONSTITUTION:A hot cathode 1 contains an ion impact resisting high melting point heat resisting material 2 and an electron emitting material 3 operable at low vacuum and low temperature having a low work function selected from yttrium boride, lanthanum boride, cerium boride, cesium oxide and cesium boride. As the material having high resistance to ion impact, metals having melting points of 2400 deg.C or more (for example, tangusten, rhenium, osmium, tantalum, molybdenum, niobium and iridium) or carbides of these high melting point heat resisting metals, or borides of these high melting point heat resisting metals. Since zirconium has a low melting point as the metal, but its carbide and boride have melting points of 3000 deg.C or more, it can be used as the material 2.

Title: Manufacture of fuel cell electrode
Inventor: MITSUTA KENRO
IPC: H01M4/88
Filed: 1984-08-16
Abstract: PURPOSE:To manufacture a fuel cell electrode having an ideal diffusion path by constructing the diffusion path like a plant root by allowing a spawn of mold to be gathered on catalytic paste. CONSTITUTION:An effective diffusion path is formed on a catalytic layer by making use of a spawn of mold. Namely, nutrient such as saccharides and starch is added into catalytic paste, applied on an electroe substrate, and sterilized, and thereafter a desired cell strain is added onto a surface to be applied and PH-adjusted at need with acid or alkali for culturing the mold in a thermo- hygrostat. After the mold is sufficiently gathered on the application surface, it is dried and calcined at need. The mold dies out upon the calcination, while the spawn is carbonated and evaporated, whereby meshes formed by the spawn is left behind in the catalytic layer. Thus, a fuel cell electrode having an ideal diffusion path can be manufactured.

Title: Medium processing device
Inventor: NUMAZAWA YOSHIHIRO
IPC: G06K13/00
Filed: 1979-12-28
Abstract: PURPOSE: To detect slip and so on for medium movement to prevent erroneous printing, by detecting the actual movement quantity of the medium in the suction and ejection mechanism part of the medium and by comparing the detection result with a logical value.  
     CONSTITUTION: When medium 9 is driven by feeding roller 1 and is sucked into inserter 10, the lower end and the upper end of medium 9 are detected successively by permeating sensor 2. In this process, a print line is detected by character detecting sensor 3. Since roller 1 is driven by the pulse motor, the number of pulses of the pulse motor between two points where sensor 2 is operated is counted and is compared with a logical value to decide whether slip exists or not in the sucking-in stage of medium 9. That is, it is decided that slip exists or mediu 9 is outside the normalized size in case that the number of pulses is larger than the logical value, and the control is not transferred to the next print line set operation in this case, and thus erroneous printing is prevented.

IPC: B01D21/24
Filed: 1981-10-29
Abstract: PURPOSE:To prevent clogging with sludge by operating a sludge discharging pump intermittently even after the stoppage of treating operation. CONSTITUTION:When a selecting switch 16 for a sludge discharge pump is turned off, both contacts MX3 and AX3 are closed by which the operation of a working timer 23 is started after the stoppage of the treatment.

It is preferable to find the maximum and minimum levels of the feeler signal S1 corresponding to luminous energy of incident light while the weft is absent, compares the difference between the maximum and minimum levels with the threshold level for alarming, and issues the alarm signal S7 when the difference deviates from the threshold level. It is also preferable that the threshold level for alarming has the same width as the threshold level for the weft detector, which judges whether the weft is present or absent.
