Title: Electrostatic charge image developing toner
Inventor: NAKAYAMA NOBUHIRO
IPC: G03G9/08
Filed: 1990-07-11
Abstract: PURPOSE:To obtain an electrostatic charge image developing toner without transfer drop-out or inferior transfer and without generation of filing on the surface of a photosensitive body by specifying a loose apparent density of a toner. CONSTITUTION:The loose apparent density of the toner is >= 0.40 g/cc. Hence the measurement of the loose apparent density is conducted with a micron powder tester to measure the tare weight of a cup for the loose apparent density measurement, to put the toner into a sieve and to vibrate the sieve and the toner is packed into the loose apparent density measuring cup. The excess of the toner is cut off by sliding a blade erected in perpendicular to the loose apparent density measuring cup and the weights of the loose apparent density measuring cup and the toner are measured and the toner weight (g) is obtained from the difference between the weight of the tare and the weight of the loose apparent density measuring cup and the toner weight is divided with an inner volume (cc) of the loose apparent density cup, then the loose apparent density (g/cc) of the toner is calculated. Thus the transfer drop-out or the inferior transfer is eliminated and the occurrence of toner filming on the photosensitive body is prevented.

Title: Measurement for strength of 2-phase structure steel plate
Inventor: NISHIMOTO AKIHIKO
IPC: G01N27/72
Filed: 1984-09-05
Abstract: PURPOSE:To achieve a highly accurate measurement non-destructively in a short time, by placing a 2-phase structure steel plate having a martensite phase into an AC magnetic field meeting a specified requirement to determine the tensile strength of a steel plate, detecting the magnetic permeability thereof. CONSTITUTION:A steel strip 1 is magnetized with a magnetization coil 2. The magnetic permeability of the steel strip 1 is measured with a coil 3. The magnetic permeability in the ferrite and martensite phase varies with the intensity of a magnetic field and the difference in the magnetic permeability between both phases become greater in a specified magnetic field range. As the specific magnetic permeability in 250-2,500A/m indicates quantitative changes in the martensite efficiently. The strength of ferrite depends on the type of steel (rough components such as C, Si, Mn and P), the strength of the steel plate varies with the amount of martensite thereby enabling the estimate of the overall strength of the steel strip from the magnetic permeability.
