Patent JP-H11111498-A (JP)
Title: Positron moderating apparatus
Inventor: MORIYA TAKESHI
IPC: G21K1/00
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To convert high energy positrons to low energy positrons at high conversion efficiency by using iridium as a positron moderator. SOLUTION: High energy positrons 3 entering an iridium ribbon 5a lose energy due to collision with iridium atoms inside the iridium ribbon 5a and are finally stopped. The stopped positrons start diffusing by receiving force toward the surface due to the work function of the positrons having negative value. At that time, most positrons undergo pair annihilation with electrons in the iridium ribbon 5a and the positrons which diffuse to the surface without being subjected to pair annihilation have energy of several eV and are discharged into the vacuum. The low energy positrons 6 discharged into the vacuum are accelerated to about 100 eV by an electric field generated between the iridium ribbon 5a and a grid 7 and are emitted forward through meshes of the grid 7.

Abstract: PURPOSE:To thin the thickness of heat insulating layer provided around a fluid path becoming high temperature by a method wherein an annular path, introducing low- temperature high-pressure fluid from a low-temperature high-pressure fluid path, is provided around the path while the low-temperature high-pressure fluid is injected from a delivery port against the outer peripheral surface of a seal member. CONSTITUTION:The low-temperature fluid, having a pressure, is introduced directly from the low-temperature high-pressure path into the annular path 20 for introducing the low-temperature high-pressure fluid, which is provided around a low-temperature fluid area 21 along the wall surface of a casing 10. This low-temperature fluid is injected from the discharging port 22 against the seal member 13 of low-temperature side. The high-temperature side seal member 12 in the low-temperature side seal member 13 contacts with two kinds of fluids, different depending on the position in the circumferential direction, therefore, the temperature distribution thereof is different along the circumferential direction. Heat may be deprived from the surface of the seal member 13 uniformly by arranging the discharging port 22 in accordance with the distribution of the temperature. Accordingly, superheat of the high-temperature side seal device may be prevented and the thickness of layer of heat insulating material provided around the high-temperature side path may be reduced.

Title: Space optical modulator using electron trap material
Inventor: JIYOOJI EMU SUTOOTEI
IPC: G02F1/17
Filed: 1990-10-11
Abstract: PURPOSE: To realize a space optical modulator which has a short response time and a high resolution by accumulating a specific electron trap material on a substrate. CONSTITUTION: The electron trap material is made of an alkaline earth metal sulfide doped with two rare earth impurities and is formed as a film 30 on a substrate 20. When this trap material 30 is irradiated with blue light, the material 30 is electrically charged and is activated and is excited to fall to the trap level. Infrared light of the excited band on the electron trap material side is absorbed by blue light and is modulated. Infrared light which pass an inactivated area of the material 30 is not absorbed and is detected by a proper method, and orange/red light emitted from the material 30 and modulated blue light are filtered by a filter, thus obtaining the space optical modulator where infrared light is modulated by blue light.

Title: Oil recovery device
Inventor: GO CHIHI
IPC: B01D45/08
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To improve the oil capturing efficiency by eliminating a pressure loss and a clogging under a comparatively simpler structure and capturing and separating an oil without rescattering a liquid film flowing along the wall of piping. SOLUTION: An air current containing oil mist and an oil film flowing along the wall of piping are guided into an oil capturing chamber 1, and the mist contained in the air current is captured by allowing the mist to collide with a capturing plate 2. In addition, a funnel-like part 5 with a diameter expanded toward the oil capturing plate 2 is formed at an outlet end 3a opposed to the capturing plate 2 of an inlet pipe 3 for guiding the air current containing the mist into the air capturing chamber 1. Thus the oil film is separated and recovered with the oil mist without being rescattered. Further, the efficiency of capturing the micro oil mist is improved by setting a net at the inlet pipe 3.

Title: Driving circuit for semiconductor light emitting element
Inventor: MANO JUNJI
IPC: H01L33/00
Filed: 1989-10-23
Abstract: PURPOSE:To reduce an overshooting current flowing to a light emitting element by partly bypassing a transient current flowing between a driving transistor and a power source when the element is switched ON. CONSTITUTION:Part of a transient current flowing to the bases of transistors 2 and 4 from a high potential power source 7 through a resistor 5 and a transistor 3 is bypassed to a capacitor 12 when a light emitting element 10 is switched ON. Since variations in the base currents of the transistors 2 and 4 are multiplied by beta to drive the element 10, the maximum transient current is reduced by beta times the bypass current, thereby reducing the overshoot of the light output of the element 10.
