Title: Thermoluminescent dosimetric element for detecting neutron
Inventor: NISHIZAWA KATSUAKI
IPC: G01T1/11
Filed: 1989-08-22
Abstract: PURPOSE:To achieve an accurate and highly efficient measurement of neutrons by covering the surface of a luminescent particle with <10>B compound. CONSTITUTION:A thermoluminescent dos imetric element for detecting neutron is positioned on one side of an test specimen and neutron is made to irradiate from the other side thereof. As a result, as the neutron passes through high- density material such as iron and is stopped by low-density material such as carbon or water or a space such as cracking, the transmission thereof is made to match properties of the test specimen. The neutron which passed through the part of the test specimen composed of a high-density material reaches the <10>B compound and alpha rays are generated from the <10>B compound. Then, a lumi nescent substance covered with the <10>B compound is excited. Thus, when the element of this invention irradiated with neutron is heated up to about 150-250 deg., it emits luminescence, which can be picked up as light signal.

IPC: H01M2/02
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reliably seal a filler hole by short-time work by blocking up the filler hole by a sealing body, and sealing the filler hole by welding the sealing body to a battery case by irradiating a laser spot to the sealing body. SOLUTION: The tip part of a truncated cone-shaped sealing body 2 is inserted into a filler hole 1a, and when a laser spot is irradiated to a reflection restraining surface 2a of the bottom surface, this is absorbed by the reflection restraining surface 2a to be changed into heat, only the sealing body 2 melts, and is welded to the filler hole 1a to be reliably sealed. At this time, to avoid the formation of a deep hole to the reflection restraining surface 2a by a small diameter laser spot, a spot diameter is set to about 1 to 5 mm, and the laser spot is irradiated by defocusing or infocusing so as to fully spread over the bottom surface of the sealing body 2. The bottom surface is formed as the reflection restraining surface 2a forming a recess shape in spite of being flat to efficiently exchange heat without scattering the laser spot to the periphery.  Thus, the filler hole 1a can be reliably sealed by work of only irradiating the laser spot, by blocking up the filler hole 1a by the sealing body 2.

An output pulse train of the encoder 7 denoting the revolution speed of the hob 1 is levelled off at predetermined intervals of time such as one revolution of the hob by means of a levelling-off circuit 14 of pulse inputs and the pulse train corresponding to sadi average value is outputted to a pulse distributing circuit 8a in order to synchronously rotate the work 13 mounted on a rotary table. In such a manner as described above, the change of the amount of lag of synchronous rotation control of the work due to the rotational irregularity of the hob is prevented, resulting in enabling to realize a highly accurate gear hobbing.
