Title: Inspection of mold for honeycomb molding
Inventor: WATANABE MITSUAKI
IPC: G01B11/30
Filed: 1989-03-01
Abstract: PURPOSE:To enable inspection of quality of a mold for a honeycomb molding quickly and accurately by making a diffusion light beam with a uniform intensity incident at a slit side end face of the mold for a honeycomb molding to detect an intensity of the light beam reaching the side of back holes by a light sensing means. CONSTITUTION:When a diffusion light beam with a uniform intensity diffused with a light diffusion plate 7 is incident from a slit 2 side of a cap 1 on a honeycomb molding, the light beam is incident evenly on thousands of numerous back holes 3 and reaches an end face on the side of the back holes being randomly reflected on internal surfaces of the back holes 3. At this point, the larger the coarseness of the internal surface of the back holes 3, the greater the degree of the random reflection, and on the contrary, the smaller the coarseness of the internal surface of the back holes 3, the smaller the degree of the random reflection. Hence, the intensity of the diffused light beam reaching the end face on the side of the back holes becomes less at a part with a larger coarseness of the internal surface of the back holes than that at a part with a smaller coarseness of the internal surface of the back holes. Such an intensity of the diffusion light beam is picked up as light density with a light sensing means 9 provided on the end surface on the side of the back holes 3 thereby enabling the learning of the quality of the mold 1 quickly and accurately.

Title: Method of treating body by low temperature plasma
Inventor: JIYOZEFU KAJIMIERUZU TERIKO
IPC: H05H1/44
Filed: 1980-04-17
Abstract: A plasma reactor, in which particulate matter is caused to interact with low temperature plasma (i.e. below 100,000 K.) comprises spaced stationary electrode structures 2, 11 of which at least one is annular, between which an arc or arcs 7 is established by a power supply which may include a thyristor (SCR) 9. The arc is pulsated and caused to orbit or circulate round the or each annular electrode structure to form a conical plasma zone between the electrodes, while particulate solids are introduced through inlets 5 to enter the plasma zone and interact with the plasma therein. Extended dwell periods and highly effective interaction are brought about by circulation and pulsation of the arc and a high particle population density. The arc can be circulated at high speed by electrical means, for example by sequential energization of plasma torches 1 in an annular array or of the segments 8 of a segmental anode, or by electromagnetic circulation of the arc attachment round an annular cathode or round a segmental anode with the help of coils 10 fitted between the segments. Examples of reactions that can be efficiently conducted by this method include the reduction of metal ores, beneficiation of low grade chromite ores, recovery of energy values from low grade carbonaceous matter such as colliery wastes and the formation of pozzolanic material and cements from siliceous minerals.

Abstract: PURPOSE: To obtain a spot network in which a fault generation position can be cut off from a power-supply passage by a method wherein a fuse, for reverse- current prevention, whose cutoff characteristic is close to that of a protective fuse is interposed and inserted in a position near a network bus. CONSTITUTION: When a short circuit or a ground fault is generated in a point B between a protect circuit breaker 10a in a supply line 4a and a fuse 14a for reverse-current prevention, a forward current I which is supplied from the side of a power-supply cable 1a exceeds a rated current IR so as to be increased to a fault current IS, and a protective fuse 8a or the protective circuit breaker 10a is cut off. In addition, a reverse current via a network bus 5 from other normal supply lines 4b, 4c flows to a fault generation point A via the fuse 14a for reverse-current prevention. In this case, since a reverse fault current which flows to the fault generation point B becomes 21S, the fuse 14a for reverse-current prevention is cut off after the time required for its cutoff has elapsed.
