Title: Production of connecting rod
Inventor: YAMASHITA HAJIME
IPC: C21D8/06
Filed: 1980-02-14
Abstract: PURPOSE: To improve a fatigue strength of a connecting rod, by partially tempering a coined end part and a near end part of a communicating stem of a connecting rod after coined.  
     CONSTITUTION: A steel piece is forged to form a connecting rod material A 0 . The forged material is then quenched, tempered and further with a coil rolled. The periphery of a coined end part 3a of the material A 0  is surrounded with a coil 7, and heated by a high-frequency energ. Thus, the end part is partially tempered. The partial tempering may be done also by flame heating or the like. The partially tempered part is surface hardened by shot peening. Consequently, there is no stretched residual stress at the coined end part 39 of the communicating stem 3, and a uniform compression residual stress is generated over the whole surface.

Title: Fuel assembly
Inventor: UEDA KIYOSHI
IPC: G21C3/32
Filed: 1990-01-30
Abstract: PURPOSE:To level an output distribution in the axial direction and to prevent output peaking from becoming excessive by having a plurality of routes of flow of a moderator and by having a channel resistor to be a resistance to circulation of the moderator on the upstream side of one of the routes. CONSTITUTION:A moderator guide member 13 is provided with a channel resistor 17 in a space between an outer pipe 15 and an inner pipe 16 and in the lower end part of the outer pipe 15. At the time of EOC, the flow rate of core water becomes high and, coupled with a relative improvement in the concentration of a residual fissile nuclide in the upper half of an effective part of fuel, it turns an output to be of a top peak type. As the result, the heat rate of a heating body lowers, the channel resistance of a water orifice 18 lowers and the core water tends to flow in between the outer pipe 15 and the inner pipe 16 with ease. When the space between the outer pipe 15 and the inner pipe 16 is filled up with the core water, the moderator guide member 13 of a fuel assembly 11 makes virtually the same operation as a usual water rod of large diameter. From BOC over to MOC, the diameter of the water rod becomes larger toward the upper part (down-stream) and thereby output peaking is prevented from becoming excessive.

The inserting face theta of the phase difference of the polarized wave converter 4c is set to a proper angle depending on the angle tau. For example, in case of the tilt angle of the incident polarized wave, tau=10 deg. and tau=20 deg., the XPD of >=30dB and 25dB is ensured. Thus, in comparing it with the characteristic of a conventional system, the XPD is improved by >=5dB.
