Title: Method and device for monitoring drawing-out of control rod
Inventor: SHIMOJU TAKANORI
IPC: G21C7/08
Filed: 1987-10-13
Abstract: PURPOSE:To enlarge the flexibility related to drawing-out of a control rod at the time of high output, and also, to execute an economical operation by using a heat flux corresponding value instead of a neutron flux as a signal utilized by a monitoring device (RBM). CONSTITUTION:First of all, when a control rod to the operated is selected, maximum four bodies of detector assemblies 1 being adjacent to the control rod are utilized. Subsequently, an average value of a signal of a detector LPRM assigned to A and B channels of the RBM is calibrated by using an average output area instrumentation (APRM) by an initialized data generating part 5. In this case, an APRM signal shows a neutron flux, therefore, it is converted to a heat flux corresponding value by multiplying a time constant of 6sec by a time constant circuit 3. When drawing-out of a control rod is started, the RBM decides by a comparing circuit 4 whether a signal of averaging circuits A, B exceeds a set value or not, and when an output of one of A and B has exceeded the set value, a drawing-out obstructing signal is outputted so that the control rod cannot be drawn out further than that. In such a way, the flexibility related to drawing-out of the control rod at the time of high output can be enlarged.

Title: Manufacture of semiconductor ic
Inventor: YOSHIDA YUTAKA
IPC: H01L21/762
Filed: 1984-12-05
Abstract: PURPOSE:To reduce the junction area between the epitaxial layer and the substrate by a method wherein an isolation region to the epitaxial layer on the substrate is formed not by the impurity diffusion from the surface of the surface of the epitaxial layer but by a diffusion from a high impurity concentration region formed in the substrate surface before epitaxial growth. CONSTITUTION:After deposition of an n type epitaxial layer 4, the impurities of an n<+> buried layer 3 and a p<+> buried layer 16 are diffused by heating. This diffusion is carried out until the iusolation buried layer 16 reaches the surface of the epitaxial layer 4 and forms an isolation region 6. In this case, antimony is introduced into the n<+> buried layer, and boron into the p<+> buried layer, so that the buried layer 3 may remain at a desired position in the epitaxial layer 4 without reaching the surface. Since boron concentration becomes lower in the neighborhood of the surface of the layer 4, diffusion is carried out through a window 17 of an oxide film 5 into the isolation region 6 at the same time with the diffusion of a base region 8, thus forming a p<+> layer 26, resulting in the increase in concentration of the isolation region. The rest of process is the same as conventional.

Title: Conductor paste and multilayer ceramic board
Inventor: SUNAHARA KAZUO
IPC: H05K3/46
Filed: 1988-10-14
Abstract: PURPOSE:To improve the adhesion strength between a conductor and a ceramic board and avoid the degradation of the adhesion strength even after being kept in a high temperature atmosphere by adding silver-copper-tungsten composite powder to silver-palladium conductor paste for a ceramic board. CONSTITUTION:Silver-copper-tungsten composite powder is added to silver- palladium conductor paste. The content of the silver-copper-tungsten composite powder is 0.05-10% to the total quantity of the conductor. paste. If the content of the composite powder is less than 0.05%, its effect is little. If the content is higher than 10%, crackings and peeling-off are developed in a conductor and the solder-wettability is degraded. The particularly recommended range is 1-6%. With this constitution, the adhesion strength of the conductor to a ceramic board can be improved and, moreover, defects such as crackings and peeling-off in the conductor can be avoided.
