Title: Particle bed nuclear fuel element with external flit containing fuel
Inventor: BIRII ERAIASU BINGAMU
IPC: G21C3/60
Filed: 1989-09-21
Abstract: PURPOSE: To prevent stress from being developed at an outer frit by providing a porous outer frit containing a fissile material and a porous inner frit for constituting an annular space to the outer frit. CONSTITUTION: An outer frit 14 is a porous cylindrical body that is concentric with an inner frit 12 an has a fissile material. Fissile heat inflates the outer frit 14 along with a fuel floor 16 and hence reduces stress developed from the heat inflation of the fuel floor 16. The outer frit 14 can be manufactured by incorporating uranium and aluminum into the frit or a fissile material as uranium alloy with another base material with a low-neutron absorption characteristic. The heat inflation of the outer frit 14 essentially matches that of the fuel floor, thus preventing stress from being developed at the outer frit.

Title: Cream colder printing squeegee
Inventor: ARAKI TARO
IPC: H05K3/12
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To control deflection in a rubber part, keep a quantity of supply of cream solder in a proper constant quantity at all times, and prevent grazing in cream solder printing onto a printed wiring board by forming a squeegee main body with a rubber part and a metallic part superimposed on the rubber part. SOLUTION: A metal mask 12 is put in superimposed relation on a printing position on a printed wiring board 13, and cream solder 14 is mounted on the metal mask 12. In this state, when the squeegee main body 16 is brought in close contact with the metal mask 12 and moved horizontally in the advance direction, cream solder 14 on the metal mask 12 moves with the result that a conductive film 15 is printed on the printed wiring board 13. At this time, since a metal plate 16b backing a rubber part 16a restrain the rubber part 16a from being warped and deflected, good tightness is retained between the squeegee main body 16 and the metal mask 12.

Title: Speaker
Inventor: SUMIYAMA MASAHIDE
IPC: H04R9/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a speaker reduced in the occurrence of gap defect or high gap defect, small in size, improved in deep low frequency reproduction and high in input resistance by providing a notch part in a direction where a voice coil is displaced at the time of amplitude-driving a diaphragm provided in the center pole, thereby preventing the voice coil from coming into contact with a center pole. SOLUTION: Since the shape of a speaker is elliptic, vibration modes different in a major axis direction and in a minor axis direction are generated and, thus, the gap defect and high gap defect caused by rolling are induced. Particularly, the rolling is often generated in the major axis direction liable to lost weight balance. Therefore, the center pole 23 is provided with two notch parts 40 in the major axis direction to extend the gap of a magnetic gap 30 in the major axis direction liable to be displaced when a voice coil 28 is amplified, thus the distance between the voice coil 28 and the center pole 23 is secured to prevent the occurrence of gap defect and the high gap defect.

Title: Scanning tunneling microscope
Inventor: NUKANOBU EIJI
IPC: G01N27/00
Filed: 1990-09-13
Abstract: PURPOSE:To eliminate heat drift in a Z axis of a scanning electron microscope by canceling a displacement attributed to a difference in linear expansion coefficient between a holding structure and a piezo-electric actuator by a difference in the linear expansion coefficient between the holding structure and a heat actuator. CONSTITUTION:A coarsely moving mechanism 2, a piezo-electric actuator 3 and a probe 4 are set in a series in a holding structure 1 and moreover, a sample 5 and a heat actuator 6 are set in series. The heat actuator is built by a three layer sandwiching an expansion plate 8 with a soaking plate 7. With such an arrangement, when a material of the holding structure 1 employs an SUS 304, that of the piezo-electric actuator 3 Pb[Zr.Ti] O3, that of the heat actuator 6 a methacrylate resin, a length of the heat actuator is 4.9mm to cancel a displacement attributed to a difference in the linear expansion coefficient between the piezo-electric actuator 3 and the holding structure 1. When the material of the soaking plate 7 employs A1016 and the expansion plate 8 the methacrylate resin, the temperature of the expansion plate 8 becomes uniform thereby achieving a higher straightness of the heat actuator.
