Title: Device for generating low speed positron
Inventor: TANAKA HIROBUMI
IPC: G21K1/00
Filed: 1991-05-21
Abstract: PURPOSE:To provide a device in which cooling of a target is not required and which can be easily shielded from neutron radiation by making high energy electromagnetic wave which is photons incident on the target. CONSTITUTION:Laser light generated by a laser generator 6 is incident from a port 7 via a half mirror 8 and bombarded with electrons being accumulated in an electron accelerating and accumulating device 5. Then high energy electromagnetic wave is generated by the inverse Compton scattering of the laser light and high energy electrons. The high energy electromagnetic wave is taken out of the port 7 and incident on a target 2 through the half mirror 8. Then the high energy electromagnetic wave incident on the target 2 generates high- speed positrons through pair creation. The high-speed positrons are incident on a moderator 3 and have their speed lowered and are then taken out as an energy-adjusted low-speed positron beam by a pullout electrode 4. The electromagnetic wave is thus incident on the target 2 whereby it is made possible to restrain generation of heat and neutron radiation.

Title: Radar antenna
Inventor: SEGAMI ITSUKAKU
IPC: G01S13/88
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To obtain a radar antenna, for example, for an underground radar with the wide frequency band of a gain by changing the center frequency of the gain of a transmitting antenna and that of the gain of a receiving antenna within a limit where each frequency band is overlapped. SOLUTION: In transmitting and receiving antennas, a standing wave with a half wavelength corresponding to each antenna gain is formed. Therefore, in the transmitting antenna with a larger dimension in the longitudinal direction where the standing wave is formed, a center frequency ft of a gain Gt is lower than a center frequency fr of a gain Gr of the receiving antenna with a smaller dimension in the longitudinal direction where the standing wave is formed.  A 3 db reduction bandwidth fw of a transmitting and receiving foldback total gain is wider than the 3 db reduction bandwidth of the antenna gain Gt of the transmitting antenna or the 3 db reduction bandwidth of the antenna gain Gr of the receiving antenna, thus increasing the bandwidth of the gain and greatly improving the performance of, for example, an underground radar that requires a high spatial resolution for a proximity range.

IPC: G01S7/48
Filed: 1995-05-16
Abstract: PURPOSE: To provide a position detection device having a low cost and high position detection accuracy and an on-vehicle laser radar using such a position detection device. CONSTITUTION: The light emitting point of an LED 58 is arranged so as to coincide with the turning center of a slit plate 60. The center line 66c of a slit 66 is formed so as to pass through the turning center of the slit plate 60. A PSD 62 is arranged behind the slit plate 60. Accordingly, the passing light flux angle α of flux passing through the slit 66 becomes always constant, regardless of the turning angle of the slit plate 60. Therefore, a light belt of always approximately the same width WD is formed in the light accepting area 62a of the PSD 62. Since the passing light flux angle a is small, the light quantity centroid GL of the light belt approximately coincides with the crossing point 62b of the center line 66c of the slit 66 and the light accepting area 62a.  That is, by measuring a distance dd, the turning angle θ of the slit plate 60 is obtained with excellent accuracy without providing a complex correction circuit.
