Title: Manufacture of foaming insulated wire
Inventor: SHIBATA NOBUYUKI
IPC: H01B13/14
Filed: 1989-05-19
Abstract: PURPOSE:To stably inject a foaming gas and stabilize foaming of resin extruded from a cylinder by cooling a piping for injecting a liquefied gas for foaming into an extruder cylinder with a pump. CONSTITUTION:Since a piping C for injecting a liquefied gas for foaming into an extruder cylinder A from a pump B, is cooled, the temperature of the liquefied gas within the piping C becomes difficult to rise. Moreover since the critical temperature or the gas-liquid interface position P of the liquefied gas moves to the extruder cylinder A side, the vaporization quantity of the liquefied gas decreases, and variation of gas injection quantity following pressure variation within the extruder cylinder A diminishes. This enables the liquefied gas for foaming to be stably supplied to a foaming material within the extruder cylinder A, foaming of the foaming material is stabled, dispersion of a foaming condition or thickness, etc., of an insulated layer b is decreased, and a foaming insulated wire having high quality can be obtained.

Title: Measuring device for measuring in field of radiation like beta or gamma rays
Inventor: MANFUREETO KEERERU
IPC: G01T1/185
Filed: 1983-07-11
Abstract: An ionization chamber of reduced size, with an end window of a diameter preferably smaller than 3 cm is mounted on the end of a hand probe containing an amplifier, the output of which goes through a cable to an indicating device. One of a set of aperture diaphragms may be slipped over the end window to reduce the area of the window transparent to beta rays. In addition to the end window, slots in the cylindrical wall of the chamber increase the solid angle through which radiation may enter the chamber. The end window and the slotted walls of the chamber are covered with tissue-equivalent material for measurement of radiation exposure dose by the electrodes of the chamber and their associated amplifier and indicator. An alternative design with a conical chamber and conical inner electrode and a smaller window provides reliable measurement, even in inhomogeneous radiation fields without the necessity of using diaphragms.
