Title: Manufacture of gd2o3-added uo2 pellet
Inventor: KOMONO AKIRA
IPC: G21C3/62
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To improve the control of sintering density by preliminarily mixing UO2 powder and Gd2 O3 powder while utilizing the fluidity and mixing the flocculated particle with a hammer mill grinding machine. SOLUTION: UO2 powder and Gd2 O3 powder generally form flocculated particles and the particles are approximately 10-1000μm and approximately 1-30μm respectively, and are non-uniform. Gd2 O3 powder is approximately 1-10wt.% in the mixed powder. When mixing particles, for example, by the V-type mixing system and ball mill mixing, a flocculated particle cannot be properly ground and the particle diameter and the mixed state cannot be finely controlled, thus resulting in a mixed powder with poor uniformity. When using the hammer mill grinding machine in combination, the particle diameter of powder and the mixing state can be finely controlled by adjusting a hammer speed, the amount of power supply, and a screen size, thus controlling a sintering density to a desired value.

Title: Driving force transfer device
Inventor: SAITO YOSHIHIRO
IPC: F16D21/00
Filed: 1986-07-16
Abstract: PURPOSE:To convert the kinetic energy of a driven shaft into the potential energy so as to obtain a buffer action, by stopping a member, which is provided in a freely rotatable manner to a driven shaft, and giving displacement to an elastic body, which is placed between this member and the other member that is integrated into one body with the driven shaft. CONSTITUTION:When printing operation of a copying machine or the like is started, a clutch 30 is turned on, and a gear 28 is coupled with a shaft 26. Thus, the driving force from a gear 22 is transferred to a driven shaft 25 via a gear train, and a drum 21 rotates counterclockwise, thereby moving a scanning mirror in the R-direction. At this time, by turning the clutch off and turning a brake 32 on, the second member 36 of a shock absorber 31 is stopped, while the first member 35 rotates counterclockwise owing to the inertia force, thereby giving diplacement to compression springs 33 and 34. As a result, the displacement of the compression springs 33 and 34 converts the kinetic energy of the scanning mirror into the potential energy, thereby stopping the scanning mirror. As a consequence, the shock of the scanning mirror at the time of, for example, stoppage can be absorbed.

IPC: G11B20/00
Filed: 1984-08-10
Abstract: PURPOSE:To adopt a so-called soft sector system without using a sector position detector by increasing the width of an address area more than the width of a data area. CONSTITUTION:A magnetic head 20 is moved to the peripheral side ridge of a designated track by a computer 50 and whether or not a prescribed block is reached is discriminated. In this case, even if the magnetic head 20 is at the side ridge of the track, since the width of the address area 60 is expanded to a data area 62, the block number of the address area 60 is detected easily by the magnetic head 20.

In this case, the prescribed time is set to a time the data area 62 of the block just passes through the magnetic head 20. Then the magnetic head 20 is moved to the inner circumference side ridge of the designated track and the remaining data is erased.

Title: Lateral transistor
Inventor: SHIMIZU GIICHI
IPC: H01L29/73
Filed: 1982-09-28
Abstract: PURPOSE:To improve the hFE, and to enhance the frequency characteristic of a lateral transistor by a method wherein a P type collector layer on an N<-> type Si substrate is surrounded with an N<+> type layer. CONSTITUTION:The P type collector layer 3 is surrounded with the N<+> type layer 4. Accordingly when a reverse bias is applied, a depletion layer generated from collector-base junction is nearly hard to extend to the substrate 1 of N<-> type base. Therefore the withstand voltage is enhance remarkably. While because the withstand voltage to be decided by avalanche breakdown is reduced, impurity concentration of the N<+> type layer 4 is selected to make the punch through withstand voltage or more to be held. According to this construction, because the punch through withstand voltage between a P type emitter layer 2 and the P type collector layer 3 is enhanced sharply, base width can be narrowed. Accordingly the high hFE and the favorable frequency characteristic fT can be obtained, and the degree of freedom in regard to the circuit design is increased.
