Title: Production of nuclear fuel pellet
Inventor: NAKAJIMA YASUO
IPC: G21C3/62
Filed: 1993-07-23
Abstract: PURPOSE:To control the density using a heat resistant crystalline cellulose as a density lowering agent for forming multiple micropores in a pellet. CONSTITUTION:Powder of uranium dioxide is admixed with the powder of oxide mixture fuel and ground before it is added with a crystalline cellulose binder, i.e., zinc stearate, having a structure as shown by the formula as a density lowering agent. It is then passed through a granulation process comprising three steps of roughening, grinding, and classification thus forming a green pellet. In the following degreasing process, it is heated at 800 deg.C or above in a mixture gas atmosphere at argon and hydrogen thus removing the crystalline cellulose by thermal decomposition or evaporation. Subsequently, it is sintered at about 1700 deg.C for about 2 hours in similar atmosphere and subjected to degassing in high temperature vacuum of 800 deg.C. Thus formed pellet is ground on the outer periphery thereof to obtain a complete pellet. This method prevents the density lowering agent from melting or decomposing thermally due to heating of plutonium thus making uniform the density of pellet.

Title: Graphic recognizing device
Inventor: ATSUMI SHIRO
IPC: G06T7/00
Filed: 1984-09-03
Abstract: PURPOSE:To detect the breaking of outer frame through a simple configulation by incorporating a comparison and decision part for deciding the presence of breaking of outer frame when the outer contour line and inner contour line extracted by the contour tracing part are identical and deciding the absence of breaking when the extracted contour lines are different to each other. CONSTITUTION:The outer peripheral line of outer frame of binary coded pattern 1 to be recognized is trace to extract outer contour points, i.e. outer contour line through a contour tracing part 2. The inner pheripheral line of outer frame is extracted, contour points i.e., inner contour line through the contour tracing part 2. Comparison/decision part 4 compares an outer contour point train and an inner contour point train and decides as an indication of the presence of breaking at the outer frame when both of the trains are identical. Such discrimination is based on the fact for the pattern showing the absence of breaking at the outer frame, the outer contour line is different from the inner contour line, whereas for the pattern showing the presence of breaking, the outer contour line is identical with the inner contour line.

Title: Adhesive for label and glass base
Inventor: SHIRAGAMI SADAHIKO
IPC: B32B17/10
Filed: 1989-07-14
Abstract: PURPOSE:To obtain an adhesive for label with high initial adhesive force, good cold water resistance and excellent alkali cleansing characteristics by incorporating a COOH group-modified PVA and a filler as active ingredients. CONSTITUTION:An adhesive for label is obtd. by incorporating 100 pts.wt. COOH group-modified PVA (A) (e.g. maleic anhydride and/or itaconic acid-modified PVA) and 10-500 pts.wt. filler (B) (e.g. clay) as active ingredients. The obtd. adhesive exhibits high initial adhesive force and an extremely good balance between cold water resistance and alkali cleansing characteristics. Therefore, as the cold water resistance is good when a beverage-filled glass bottle on which a label has been stuck with this adhesive is cooled and the peeling of the label with an alkali is easy to perform after recovery of the bottle, it is useful especially for an adhesive for label for a glass bottle for beverage.

Abstract: PURPOSE:To prevent contamination of the circumference due to outflow and scattering of a developer in case when the developer is replenished, by providing a magnetic force device on a discharge port of the developer, and executing a control of discharge and obstruction of discharge of the developer by erasing or applying the magnetic force. CONSTITUTION:An auxiliary cap 12 is fitted into a developer vessel body 10 containing a developer T, a magnet 17 is fixed as inserted to an inserting guide 14 of the auxiliary cap 12, and thereafter, a cap 15 is detached, is turned upside down, and is placed on a hopper H for replenishing the developer. In this state, the magnetic developer T is absorbed by magnetic force of the magnet 17, and discharge from a discharge port 13 is obstructed. Subsequently, when a holder 16 is drawn in the direction as indicated with an arrow, and the magnet 17 is drawn out of the inserting guide 14 of the auxiliary cap 12, magnetic force of the discharge port 13 annihilates, therefore, the developer T is discharged automatically by its gravity, drops into the hopper H, and the developer is replenished by a developer feed-in device.

IPC: F16H19/08
Filed: 1988-07-25
Abstract: PURPOSE:To decrease the number of parts used and reduce the man-hours for assembling by fitting a gear formed in a single piece from a torque transmitting segment gear and an angle transmitting segment gear on an output shaft, and meshing the angle transmitting segment gear with a gear on a potentiometer shaft. CONSTITUTION:When a motor 12 is started, rotation of motor shaft 13 is decelerated by gears 14, 16, 17, 19 and transmitted to a gear 22 and further to an output shaft 5 by means of meshing of a small gear 21 with a torque transmitting segment gear 29, and at the same time, to a potentiometer 24 by means of meshing of an angle transmitting segment gear 30 with a gear 26. When a valve is opened to a certain degree of opening to rotate the output shaft 5 for a certain angle, the meter senses it through meshing of the gears 30, 26 and emits a signal, and the motor 12 is stopped to cause stop of the valve at a certain degree of opening. Because the gears 29, 30 are formed in a single piece, the space occupied by gears is shrunk compared with the case where a separate angle transmitting gear is provided. There is no need for screw fitting the angle transmitting gear.
