IPC: H02M3/00
Filed: 1979-11-30
Abstract: PURPOSE: To prolong the life of the cell used in an electronic timepiece by supplying the reduced cell voltage to a portion or the whole of the electronic horological circuit.  
     CONSTITUTION: When a signal ψ applied to a voltage-reducing circuit comprising capacity elements 65 and 66 and MOS transistor switches 67 and 68 is low, the switches 67 and 68 are alternately turned on and off. When the switch 67 is on and the switch 68 is off, the capacity 65 is charged by a lithium cell 69. When the switch 67 is off and the switch 68 is on, the electric charge stored in the capacity 65 is partially stored in the capacity 66, and the voltage, 2.8W3.0V, across the capacity 65 is divided into the voltage determined by the capacities 65 and 66. The reduced voltage is supplied to a portion or the whole of an electronic horological circuit comprising an oscillation circuit, a frequency divider circuit and the like. Besides this, various voltage-reducing circuits can be used.

IPC: C23C22/84
Filed: 1987-06-23
Abstract: PURPOSE:To form a stable and uniform colored surface which withstands molding after coloration with a relatively simple operation by immersing Ti (alloy) into an oxidative melt bath. CONSTITUTION:The Ti (alloy) material 1 delivered from a pay-off reel 2 is immersed in the melt bath of a fused salt bath 4 and the colored surface of various color tones is formed on the surface by controlling the immersion temp., more particularly the treatment time.

Title: Fuel assembly
Inventor: TAMIYA TADASHI
IPC: G21C3/328
Filed: 1992-06-16
Abstract: PURPOSE:To heighten a degree of enrichment of an averge fissile material of fuel rods in the outermost circumferential row and contrive high burnup of fuel by reducing surplus reactivity at the beginning of burn up. CONSTITUTION:An flammable absorber is added to a third to three quarters 2 of total fuel rods 1, 2 arranged in the outmost circumferential row of a fuel assembly and radially arranged periodically. Surplus reactivity is sharply reduced by absorbing surplus neutrons in the flammable absorber at beginning of burn up. Since the flammable absorber burns as burn up proceeds and contribution to neutron absorption reaction is lessened, average burn up reactivity of a reactor core of the fuel assembly lessens throughout operation. If an indefinite doubling rate of the fuel assembly is small at the beginning of burn up, a local output peaking coefficient can be enlarged because at the time the average output of the fuel assembly is small. This can heighten a degree of enrichment of a fissile material of the fuel rods arranged in the outermost circumferential row.

Abstract: PURPOSE: To prevent over-exposure or under-exposure from occuring by so constituting the light receiving part as to have the aperture characteristic of measuring light by taking the quantity of photographing light exposing the film plane in advance at the closing operation of shutter blades.  
     CONSTITUTION: A shutter blade 2 is formed with a light receiving stop part 2c which determines the aperture characteristic of a light receiving part 1b. When the shutter is released, the shutter blades 2, 3 start turning clockwise by way of pins 6, 7 and the end part (minimum area part) of the stop part 2c opens the part 1b, then the photometric integration of photographing light by the part 1b is started, after which an aperture 1a opens to start exposure.
