Title: Corrosion monitoring of blast furnace pig iron tapping trough
Inventor: IGAKI YOSHIHIRO
IPC: G01B21/00
Filed: 1986-01-14
Abstract: PURPOSE:To enable continuous monitoring of corrosion state of the entire internal wall surface of a pig iron tapping trough during the operating of the pig iron tapping trough, by burying a wire type cable sensor into the pig iron trough. CONSTITUTION:A square wave pulse generated by a pulse generator 22 enters a cable sensor 10 via sampling unit 18, a switch 16 and a cable 12 when the switch 16 is at the cable 12 position, and further a cable 14 after reaching the other end of the sensor. At the end (a fixed contact of the switch 16) of the cable 14, the pulse is reflected to reverse the course. As a result, when a potential at a feeding end is observed with oscilloscope 24, a reflected wave arrives from the end of the cable 14 and a combined wave with the transmitted wave is observed. When the transmitted wave vanishes, the reflected wave alone is observed and it also vanishes in turn. Where as corrosion progresses at parts (a), (b), (c) and (d) of the iron pig tapping trough 20 to reduce the space between the molten steel and the cable sensor and the temperature of the cable sensor rises locally, a reflected wave appears at these parts as shown by Ca, Cb, Cc and Cd of a curve.

Title: Electrophotographic sensitive body
Inventor: YANAGIUCHI KAZUKI
IPC: C07D519/00
Filed: 1991-01-22
Abstract: PURPOSE:To obtain the photosensitive body superior in sensitivity and dark decay resistance by using an electric charge generating material and a charge transfer material in a weight ratio of of 1/20-1/10 and also an antistatic agent in an amount of <50ppm for the photosensitive layer. CONSTITUTION:The photosensitive layer formed on a conductive substrate contains the charge generating material of a bisazo pigment of formula II or a polycyclic quinone compound of formula III and the charge transfer material of formula I in a generating material to transfer material weight ratio of 1/20-1/10, and a resin and further the antistatic agent in an amount of <50ppm. If an amount of charge generating material is too small in the photosensitive layer, sufficient sensitivity is not obtained. If too much, dark decay increases and also fatigue due to repeated charging is also raised. The antistatic agent brings about increase of sensitivity in combination with the charge transfer material, thus permitting the obtained single layer type electrophotographic sensitive body to be enhanced in sensitivity.
