Title: Core of nuclear reactor
Inventor: HAYASE TAMOTSU
IPC: G21F9/00
Filed: 1989-01-11
Abstract: PURPOSE:To flatten output distribution, etc., and to efficiently decrease transuranium elements TRU by constituting the core in such a manner that the compsn. ratios of americium Am and curium Cm of the TRU are higher in the peripheral part of the core than in the central part of the core. CONSTITUTION:Fuel which is lowered in the compsn. ratio of the Am or Cm is loaded in a circular cylindrical core region 1 and the fuel which is increased in the compsn. ratio of the Am or Cm is loaded in the region 2 around the region 1. The neutron fission sectional area of the respective isotope elements of the Am or Cm contained in the TRU has the larger sectional area with respect to fast neutrons as compared to the same sectional area of neptnium 237. The fission reactivity of the neutrons increases and the output density and neutron flux level increase as well in the region where the compsn. ratio of the Am or Cm is increased. The output density and neutron flux distribution are flattened in this way and the high neutron level, etc., are attained within the same heat limit.

Title: Magnetic tape cartridge
Inventor: MINAMI SHIGEO
IPC: G11B23/027
Filed: 1988-01-09
Abstract: PURPOSE:To prevent the generation of the winding looseness of a tape by pressing the tape with an elastic body held in a magnetic tape cartridge at the time of off-loading a magnetic tape device and canceling the pressing of the tape with the elastic body at loading. CONSTITUTION:When a cartridge 1 is not loaded and closed, an elastic body 5 is pressed to a magnetic tape 4 by a spring 3 and an elastic supporting part 7, and the looseness of the tape 4 is prevented. Next, when it is loaded, the cartridge 1 is opened, and the elastic body 5 is separated from the tape 4 by force by the difference of an air jet pressure receiving area at the both edges of the supporting part 7 by an air jet 11. A flip flop member 10 is displaced from a neutral position by the jet 11, as a result, the elastic body 5 is maintained at a condition separated from the tape 4. When the cartridge 1 is closed, the member 10 is displaced from the neutral position in an inverse order to the above-mentioned, the elastic body 5 pushes the tape 4. Thus, the winding looseness of the tape is prevented.

Title: Removing method of oxidized film from rolled plate of metallic titanium
Inventor: KITAZAWA NOBORU
IPC: B21B3/00
Filed: 1982-01-13
Abstract: PURPOSE:To make grinding without spraking possible with small pressurizing force and high rates of grinding in the stage of grinding a rolled plate of metallic Ti with nonwoven fabric elastic grindstone by performing rough and finish grinding with two kinds of grindstone having specific moduli of elasticity. CONSTITUTION:A rolled plate of metallic Ti is first ground to a hairline-like rough surface with nonwoven fabric elastic grindstone having 0.35-0.45kg/mm.<2> modulus of elasticity, then the plate is ground to a smooth surface with nonwoven fabric elastic grindstone having 0.20-0.33kg/mm.<2> modulus of elasticity. Here, if the modulus of elasticity of the grindstone is too low, the grindstone does not cut into the hard scale layer 2 on the surface of the plate 1 and grinding does not progress. If the modulus of elasticity is too high, the grindstone is too hard and flake-like projecting surfaces 5 which are not easily annihilated even when ground next with the elastic grindstone of low modulus of elasticity and fine abrasive grains are formed. In addition, sparks are generated and cause reoxidation. If the elasticity of modulus of the grindstone for finish grinding is too low, the efficiency of grinding is smoothing the rough surface is low and if the modulus is too high, the rough surface is smoothed.

Title: Controlling device of industrial sewing machine
Inventor: TAKADA KAZUAKI
IPC: G05B19/416
Filed: 1983-01-14
Abstract: PURPOSE:To improve the stopping accuracy at the stop of a fixed position by delaying the braking period of a braking mechanism properly on the basis of the rotational frequency of a machine when a machine needle reaches a stop position. CONSTITUTION:A rotational frequency detecting signal TGS is delayed little by little by buffer circuits 1-3, resistors R1-R3 and capacitors C1-C3. The delayed variable is changed in accordance with the rotational frequency of the machine. When the machine needle reaches a prescribed position, a transistor (TR) 3 is driven by a signal delayed for a period corresponding to the rotational frequency of the machine at a moment just before reaching to the prescribed position and current is made flow into a brake coil BR to work the braking mechanism. Thus, the working period of the braking mechanism is properly delayed in accordance with the rotational frequency at the reach of the machine needle to the prescribed position, so that the stopping accuracy at the stop of the fixed position can be improved.

Abstract: PURPOSE:To efficiently obtain a regenrative signal and a track deviation signal by using a second harmonic wave beam as the regenrative signal and a basic wave beam for a tracking servo in an SHG element. CONSTITUTION:The basic wave beam 2 and the second harmonic wave beam 3 of the SHG element are converged together on a recording disk 4 and a passing pit 5.

Abstract: PURPOSE: To plan more effective defrosting of an air side heat exchanger by controlling a solenoid valve provided on upper one of upper and lower air side heat exchangers defined by dividing an air side heat exchanger according to information from a pressure sensor while an air source heat pump water chiller boiler is being operated in a defrosting mode. CONSTITUTION: An air side heat exchanger 2 is divided into upper and lower portions and the upper portion is provided with a solenoid valve 9 and a check valve 10, and refrigerant flows through the solenoid valve 9 during defrosting cycle and flows through the check valve 10 during heating cycle. When a high-pressure pressure sensor 7 detects a first defrosting-completion judging value after defrosting operation is started, a controller 6 judges that frost on the air side heat exchanger 2 has been removed to a certain extent, frost still remains partially, portion where defrosting has been completed is of low thermal efficiency so that high-pressure pressure abruptly rises and the high pressure sensor 7 judges that defrosting-completion judging value has been detected.  The controller 6 closes the solenoid valve 9 in order to stop allowing refrigerant gas to flow into upper side of the heat exchanger and make the refrigerant forcedly flow into lower side of the heat exchanger.
