Title: Convergence measuring instrument
Inventor: SHIRAKI KENJI
IPC: H04N17/04
Filed: 1978-02-02
Abstract: PURPOSE: To make a convergence adjustment easily by automatically measuring raster shifts of three primary colors.  
     CONSTITUTION: Photo detector 2 is made in contact with any measured point on screen 8 of color television receiver 1, thereby making possible to detect rasters. Light detected by this photo detector 2 is supplied to measuring instrument 7 and its result is displayed numerically. At a measurement time, rasters of only primary color R, for example, among three primary colors R, G and B are projected and start-signal generating circuit 6 applies a signal to time measurement circuit 4, by detecting the fall of one vertical synchronizing signal, to make time measurement circuit 4 start its measurement, thereby measuring the time until the scan of an electron beam reaches a position provided with photo detector 2. As for G and B, the same measurements are made to compare the both in terms of time, and the variable resistor for convergence adjustments is adjusted to equalize the both.

Title: Fuel distribution pipe made of resin containing reinforced fiber and its manufacture
Inventor: KOJIMA SUSUMU
IPC: B29K105/06
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a fuel distribution pipe which may not be damaged by vibration, by orienting to a cross direction a reinforced fibers in a distributing pipe zone in which a bending moment is approximately set to be zero between fulcrums when vibration in the cross direction is generated, and orienting to a longitudinal direction the remaining reinforced fibers in the distributing pipe zone, in the fuel distribution pipe. SOLUTION: A fuel distributing pipe 10 has a main pipe, and four storage holes 14 are arranged to the circumferential surface of the main pipe at equal intervals. Also, two flanges 16 are arranged on the circumferential surface of the main pipe, and the fuel distributing pipe 10 is attached to an engine main body through the flanges 16. When such a fuel distributing pipe 10 is formed of resins containing reinforced fibers, the resins are poured from a position shown by an arrow G corresponding to the zero position of the fuel distributing pipe 10 into a resin forming mold. Here, a nonparallel range H is formed in a zero position where a bending moment is approximately zero, therefore, a problem concerning strength is eliminated.  While, the orienting direction of the reinforced fibers is made to be approximately in parallel to the longitudinal direction of the fuel distributing pipe 10 in the remaining ranges, therefore, strength in a cross direction is enhanced.

Filed: 1978-02-08
Abstract: PURPOSE: To increase reactor power with a certain power increase rate by mixing two kinds of liquid poisons having different neutron absorption corss section within heavy water moderator and varying concentration ratio between respective liquid poisons during increasing reactor power increase.  
     CONSTITUTION: For reducing operation frequencies of poison removal during power increase, 46000 barns of neutron absorption cross section of gadolinium is 34 times larger in comparing to 1350 barns of boron ( 10 B).

Consequently, in case of containing a suitable amount of gadolinium within heavy water, from burnup effects of which taking notice of the reactor power being automatically increased, boron and gadolinium are used as liquid poison. In calculating heavy water reactor with neutron flux level of 1 × 10 14  n/cm 2 .sec under the rated output, the power may increase at fixed speed of 0.3%/hr up to 50% - 100% output with the burnup of gadolinium.
