Patent JP-S6365409-A (JP)
Title: Processing method for optical fiber core
Inventor: HOSOYA HIDEYUKI
IPC: G02B6/24
Filed: 1986-09-06
Abstract: PURPOSE:To omit an excess length processing member in a connection box by contracting a storing container in a drawing end so that excess length forms a loop with a small bending radius and expanding the storing container in a connection box so that the excess length forms a loop with an allowable bending radius. CONSTITUTION:The bending radius r2 formed at the time of expanding the storing container 30 and storing the excess length 17 of an optical fiber core 16 in the container 30 like a loop is >=30mm of an allowable value. In case of contracting the excess length 17 and storing it in a drawing end protection tube 22, the loop of the excess length 17 is distorted and the bending radius is turned to r1 (e.g. 20mm). After completing laying and releasing the drawing end, the storing container 30 is expanded, returned to the original state and stored in the connection box, so that the radius r2 is turned to >=30mm the allowable value. Consequently, it is unnecessary to newly execute excess length processing in the connection box.

Abstract: PURPOSE:To reduce the number of detectors and circuits attached thereto without a significant drop in an X-ray utilization efficiency by covering an object to be detected or a detector with a mask coded by a function similar to an orthogonal function to obtain a data. CONSTITUTION:In a detection method by which transmission X rays are detected by the irradiating an object 4 to be detected with X rays to obtain an X-ray absorption coefficient distribution image of the object 4 to be detected, a mask 11, for example, with 8X8 pixels coded by a function similar to an orthogonal function so arranged to cover about a half of a photographic area in substance is used to obtain a data.

Then, in an X-ray photography, for example, eight detectors 12 are used to irradiate the object 4 to be detected. The masks 11 are moved by one frame per irradiation. When the masks 11 are moved, for example, to the right, the object 4 to be detected is exposed outside the masks 11 sequentially starting from a leg part thereof. Hence, in substance, two of the same masks 11 are used by being connected together. Thus, intensity of signals can be determined at parts of a photographic area divided by combining data obtained.

Title: Electrically conductive belt
Inventor: NISHIKAWA MANABU
IPC: G03G15/16
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To ensure a resistance which nearly does not tend to depend on environmental changes, such as a temperature or humidity change as well as to make the intrasurface resistance of an electrically conductive belt stabilized by using a high molecular polymer composition containing an antistatic agent having boron atoms. SOLUTION: This electrically conductive belt 6 comprises a high molecular polymer composition, containing an antistatic agent having boron atoms. When a 300 V voltage is applied repeatedly 200 times to the belt 6 for 10 sec each, while suspending application for 3 sec, the initial volume resistance R1 of the belt and the volume resistance R2 after the repeated application have a relation 0<=LogR2-LogR1<=1.5. When Log(R2/R1)<1.5, an image becomes stabilized, the dependency of resistance on an environmental change lowers and the image is hardly affected by the ambient temperature and humidity. The relation between the volume resistance Rs at 23 deg.C and 50% relative humidity and the volume resistance Rh at 30 deg.C and 90% relative humidity preferably satisfies the expression 0<=LogRs-LogRh<=2.
