Patent JP-S61231614-A (JP)
Title: Dc power supply unit
Inventor: YAMAMOTO YOSHIO
IPC: G05F1/00
Filed: 1985-04-05
Abstract: PURPOSE:To prevent an output voltage from lowering to be produced at changeover between constant voltage DC power supplied by providing a means selecting a reference voltage for voltage control in response to the anode and cathode potential of an output diode to each constant voltage DC power supply. CONSTITUTION:The anode potential VOA of the output diode D1 and the cathode potential V0 are compared by a voltage comparison circuit 8 in a constant voltage DC power supply section 21. When the result of comparison shows an H level, the potential V0 is selected as the reference potential for the voltage control via a transistor (TR) Q1. On the other hand, when the result is at an L level, the potential VOA is selected as the reference potential for voltage control via a TR Q2. Similarly, the reference potential is selected for the constant voltage DC power supply section 22. Thus, the reduction in the output voltage produced at the changeover between the constant voltage DC power supplies is prevented.

IPC: B23K26/38
Filed: 1991-04-05
Abstract: PURPOSE:To settle such problems that dross adheres to the reverse side of an object to be worked since a molten metal does not flow smoothly in the vicinity of a working start point in the case of laser beam machining of the object to be worked of a thick plate, and a working failure is generated due to a fact that this dross raises a temperature of the object to be worked, by the laser beam machining method of this invention. CONSTITUTION:A laser beam is subjected to reciprocating scanning in a section on a working path after working is started, the laser beam is returned to the working start point again, and thereafter, regular working is executed. Since the laser beam is subjected to reciprocating scanning in a section on the working path after working is started, width of a cut groove in the vicinity of the working start point in which the generation frequency of a working failure is high is widened, and since a molten object melted by the laser beam can be eliminated smoothly, it can be prevented that dross adheres to the reverse side of an object to be worked and stable working can be executed.

Filed: 1988-03-29
Abstract: PURPOSE:To enable a safe and stable operation, by diminishing a pellet diameter of a mixed fuel assembly to around 0.1mm less than that of an uranium fuel assembly. CONSTITUTION:Fuel rods and water rods are orderly arranged in a matrix of 8 rows and 8 columns. A fuel rod of a mixed fuel assembly has the same structure as that of an uranium fuel assembly as shown in the figure, and a diameter of the fuel pellet is 10.3mm. In this case, by making the diameter of the mixed fuel assembly to be around 0.1mm less than that of the uranium fuel assembly, a water to fuel ratio of the mixed fuel assembly is larger than that of the uranium fuel assembly. Consequently, a neutron flux spectrum is softened to almost the same level as that of the uranium fuel assembly, a control rod value is improved and a reactor shut-down margin can be kept successfully.

IPC: G03G15/00
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To inexpensively perform the positional deviation detection of an image, by detecting the marks of all colors with a single light emitting source by separating a light receiving element and an entering surface by a specified distance. SOLUTION: The light receiving element 18 constituted so as to be separated from the entering surface water emitted light from alight emitting element 16 enters a slit 17 (the surface of a slit member 17a on the side of the light emitting element 16) by equal to or more than a distance equivalent to the long side of the light receiving surface in the case that the light receiving surface of the light receiving element 18 is a rectangle (one side in the case of a square) or the distance equivalent to the diameter of a circle in the case that the light receiving surface of the light receiving element 18 is circular.  Thus, when the light receiving surface of the light receiving element 18 is at a position separated from the slit 17, scattered light 4 is diffused, so that the scattered light does not reach the light receiving surface of the light receiving element 18 and passes around the light receiving surface. Thus, sufficient contrast is obtained even for the mark of yellow toner or the mark of magenta toner.
