Title: Formation of resist pattern
Inventor: TANAKA HIROYUKI
IPC: H01L21/027
Filed: 1989-12-18
Abstract: PURPOSE:To form large and small resist patterns with the same accuracy by selectively silylating the exposed or unexposed parts of a resist and forming a silylated layer after the resist on a substrate is selectively exposed, and concurrently etching the organic resin of a lower layer. CONSTITUTION:The organic resin 3 as the lower layer is applied on a silicon substrate 1, and a selective silylating resist 4 is applied thereon. After the resist is selectively exposed, the selective silylating resist 4 is silylation-processed and the exposed parts 41 and 42 are transformed into silylated parts 43 and 44, which are vertically plasma-etched by an oxgen-reactive ion plasma etching method. Consequtively, the unexposed parts are eliminate from the resist 4, and SiO2 films are formed on the surfaces of the silylated parts 43 and 44, which remain without being etched and the resist patterns contg. the organic resin 3 are formed on its just under parts. Thus, the large and small resist patterns can be formed with the same accuracy.

Abstract: PURPOSE:To form a composite metallic plate which is superior in adhesion and has a favorable form, by a method wherein at the time of deaeration, the deaeration is performed from a minute part at the first stage and the whole of the metallic plate is deaerated in order. CONSTITUTION:Steel sheets 101, 102 uncoiled through coils 11, 12 are run in a line direction A, resin is applied to laminating surfaces in coating chambers 21, 22 and they are dried and heated in drying furnace 31, 32. Then the steel sheets 101, 102 are laminated together and deaerated with a plurality of sets of deaeration roll groups 4. In this instance, since a deaeration part with a roll 4-1 is narrow, a bubble is pressurized with the roll and fled from that place to a part where roll neither pressurizes nor touches. Then when a continuing narrow part is pressurized with a deaeration roll 4-2, the bubble of that part is fled in the direction where the roll 4-2 does not touch. Similarly the bubble is fled outside of a roll 4-3 with the roll 4-3 and finally discharged outside of a width of a steel sheet with a roll 4-4. Then the steel sheets are pressurized, pressure-contacted with a pressure-contacting roll 5 and become a sheet of a composite steel sheet 12. Then after the same is cooled by passing through a cooling device 6, the same is wound up round a wind-up coil and becomes a composite coil 7.

Title: Pll circuit
Inventor: TAKADA MASATOSHI
IPC: H03L7/093
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent a PLL circuit from getting into a deadlock state and to make it possible to return into a normal rock state by detecting the phase difference between a reference signal and a feedback signal and discharging an error signal or control signal under the control of a reset signal. SOLUTION: A phase comparator 12 detects the phase difference between the external reference signal of specific frequency and a feedback signal from a voltage-controlled oscillator 18 and outputs a control signal UP or DOWN. A charge pump 14 outputs an error signal corresponding to the phase difference according to the control signal from the phase comparators 12 when the reset signal is inactive. Here, the reset signal becomes active when a PLL circuit 10 possibly comes to a deadlock or has come to the deadlock. At this time, the charge pump 14 outputs the error signal which lowers the voltage level of the control signal irrelevantly to the control signal. Then the output signal and feedback signal are outputted from the voltage-controlled oscillator 18 through a loop filter 16.

Abstract: PURPOSE:To improve sorting precision by installing a cylindrical body rotating on its central axis, plural partition plates radially inside the cylindrical body, plural weirs circumferentially inside the cylindrical body and a feeding opening for material to be sorted in the approximately central part of an opening in the upper part of the cylindrical body. CONSTITUTION:A mixture fed from a feeding chute 15 in the central part of a rotational cylindrical body 3 freely falls while it strikes on radial partition plates 12 turning together with the rotational cylindrical body 3. Thereby the particles of the mixture are given revolutionary movement around the rotational shaft of the rotational cylindrical body 3 simultaneously with the fall of the particles of the mixture. When the falling mixture reaches terminal velocity, it continues to fall at a constant speed. During the fall, the mixture is horizontally accelerated by centrifugal force given by the revolutionary movement to move in the outer circumferential direction in a parabola generally. Since the angles of the parabola differ according to the difference in specific density and the difference in the height of circumferential weirs 13 is provided, the objects which strike on the circumferential weirs 13 and fall in each section are sorted by the difference in specific density. At the same time, a screen 14 excludes substances having excessively large particle size.

Title: Production of uo2 pellet
Inventor: YATO TADAO
IPC: G21C3/62
Filed: 1988-12-27
Abstract: PURPOSE:To enable the control of the sintering density and crystal particle diameter of a pellet at the same time to respective specific levels by adding a specific pore-forming agent to UO2 powder used as a raw material and forming the mixture. CONSTITUTION:UO2 powder having high activity is uniformly mixed with 0.3-1.4wt.% of a pore-forming agent having an average particle diameter of 5-500mum (preferably 10-100mum) and decomposing and dissipating at <=600 deg.C. The mixture is roughly molded, disintegrated, granulated to particle size of 2,000mum, preferably 1,000mum, filled in a mold and molded. The compression molding is facilitated by adding a lubricant to the raw material powder or applying a lubricant to the mold. The pore forming agent is e.g. ammonium acetate, ammonium carbonate or ammonium oxalate and the lubricant is e.g. stearic acid or zinc stearate. The sintering density of a UO2 pellet can be controlled within the range of 94-97% TD even in the production of a UO2 pellet having crystal particle diameter of >20mum from UO2 powder having high activity. The gases generated by nuclear fission during combustion can be more effectively retained in the pellet by this process to improve the combustion stability.
