Title: Measuring degree of burning of nuclear fuel
Inventor: KOBAYASHI IWAO
IPC: G21C17/06
Filed: 1978-05-22
Abstract: PURPOSE: To easily and non-destructively measure the quantity of fissionable unclides, by treating neutrons resulting from the unclear fission caused by neutron irradiation as non-thermal neutrons, treating neutrons from an irradiating source as thermal neutrons and detecting only the non-thermal neutrons.  
     CONSTITUTION: The neutrons from the irradiating neutron source 2 are projected against a unclear fuel 1 to cause the unclear fission of the nuclear fuel 1. The neutrons resulting from the unclear fission are treated as the non-thermal neutrons. The neutrons from the neutron source 2 are treated as the thermal neutrons. Only the non-thermal neutrons are detected to meausre the quantity of the fissionable nuclides of the nuclear fuel 1. The neutron source (Cf-252) 2 is movably placed on one side of the nuclear fuel assembly 1 under water. A neutron detector 3 is placed together with a gamma-ray shield 4 of lead on the opposite side of the fuel assembly 1. The neutron detector 3 is coated with a substance 5 such as Cd, B, etc. for absorbing the thermal neutrons. Only the  non-thermal neutrons can penetrate the substance 5. To raise the dedtection efficiency, a high-sensitivity detector is used for the thermal neutrons. The non-thermal neutrons are conducted into a hydrogen-containing substance such as paraffin so that they are detected as thermal neutrons.

Title: Photographing lens which makes use of floating
Inventor: MATSUSHITA TAKASHI
IPC: G02B9/64
Filed: 1987-03-16
Abstract: PURPOSE:To permit automatic focusing which can satisfactorily correct aberrations for a wide range of objects by forming a photographing lens of >=2 groups and subjecting the two lens groups to floating movement in such a manner that the air spacing changes at a prescribed rate. CONSTITUTION:The photographing lens is constituted, successively from an object side, of the 1st-3rd lens groups I-III having positive, negative, and positive refracting powers. The group I is moved linearly and the group II nonlinearily so as to change the air spacing monotonously by making use of the floating to move the groups I, II respectively independently at the time of focusing the lens from an infinite object to a short distance object. The moving ratio of the group II to the group I corresponding to the rate of the change in the air spacing between the groups I and II decreases monotonously if the respective moving quantities m1, m2 of the groups I, II are so selected as to satisfy the conditions expressed by equation I at this time. Then, the sensitivity changes at the smaller width at the time of infinity and at the time of unmagnification photographing. The fluctuations in aberrations at the time of focusing to a wide range of the objects from the infinite object to the short distance object for which the photographing magnifications are up to unmagnification are satisfactorily corrected and the automatic focusing with good applicability is executed according to this constitution.

Title: Charge control method for storage battery
Inventor: TANAKA AKIFUMI
IPC: H01M10/44
Filed: 1989-03-14
Abstract: PURPOSE:To prevent overcharge by finishing charge when the charge integral value, which multiplied the difference between charge voltage and open-circuit voltage in completely charged conditions by charge time, has become larger than the discharge integral value, which multiplied the difference between said open-circuit voltage and discharge voltage by discharge time. CONSTITUTION:The quantity of charge/discharge currents is stored in a memoryode MD wherein voltage varies about + or -50mV by the quantity of charge/ discharge currents. A resistance R3, and a Zener diodes Z1 and Z2 are connected to power source lines L1 and L2, and open-circuit voltage Vb is set to a point B. Moreover, the difference between the voltage Va at a point A, that the battery voltage during charge is divided with resistances R4-R6, and the voltage Vb is amplified with an operating amplifier OP. R6 is adjusted in advance to realize Va-Vb=0 in the circuit-open conditions at the time of charge completion. When discharge advances the voltage of MD falls through a resistance R1, and when charge advances the voltage of MD rises through a resistance R2. When the voltage of MD turns from negative to positive during charge, a comparator C outputs signals so as to turn off a photocoupler PC and turn off a relay Mg. Hereby overcharge can be prevented.
