Title: Method for analyzing stability of power system
Inventor: FUNAHASHI TOSHIHISA
IPC: H02J3/24
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To quickly obtain a solution by fixing entire input for obtaining a stability limit phase angle by an equal area method, by obtaining a phase angle when final disturbance occurs, and by comparing the stability limit phase angle with the phase angle when disturbance occurs for judging stability. SOLUTION: By using an equal area method, a stability limit phase angle δc2 after path-reclosing time t2 is obtained according to an expression cos-1 2δ0+π)sinδ0-cosδ0} (in the expression, δ0 indicates the phase angle of time t0 before a fault) (S1). Then, Po, Vi, Vb, Xd', Xe, t0, ωn, ω1, M, and δ1 are set to generator electric output, the generator internal voltage, the infinite bus voltage, the generator excessive reactance, the transmission line reactance, the time before the fault, the generator rated angular velocity, the angular velocity of a generator at t1, a generator unit inertial constant, and the phase angle of t1, respectively. Then, the final disturbance occurrence time t1 is given, and the phase angle δ2 after the final disturbance occurrence is obtained (S2).  More specifically, δ0=sin-1 P0(Xd'+Xt+Xe)/ViVb}, ω1=ωnP0(t1-t0)/M, and δ1= ωnP0(t1-t0)/2M}+δ0 are substituted for δ2= ωnP0(t2-t1)2/2 M}+ω1(t2-t1)+δ1 for obtaining δ2. It is judged to be stable, unstable, and critical in the case δ2<δc2, δ2>δc2, and δ2=δc2, respectively.

Title: Secondary electron detector for electron ray device
Inventor: OOTAKA TADASHI
IPC: G01N23/225
Filed: 1984-04-06
Abstract: PURPOSE:To achieve high secondary electron detection efficiency even for an electron beam with low acceleration voltage by combining an electric field and a magnetic field and installing a deflector which introduces only secondary electrons into the detector without deflecting the electron beam. CONSTITUTION:In a scanning microscope or similar device, when an electron beam 5 is irradiated upon a sample 2 and secondary electrons discharged from the sample 2 are detected by a secondary electron detector 4, a deflector is installed on the beam axis. In the deflector 8, deflecting plates 8-1 and 8-2 and earth electrodes 8-3 and 3-4 are installed facing each other to produce an electric field. And, deflecting coils 8-5 and 8-6 are installed to produce a magnetic field. Therefore, forces 9 and 11 produced in the electric field and the magnetic field are equal and in counter directions thereby preventing any positional shift of the electron beam 5. Additionally, only secondary electrons are introduced into a detector 4 thereby enabling secondary electrons to be detected with high accuracy.

Title: Multilayer printed wiring board
Inventor: NAKAMURA HISAKAZU
IPC: H05K3/46
Filed: 1990-03-20
Abstract: PURPOSE:To improve adhesion properties and heat resistant properties by forming an insulation layer which is connected with a signal circuit as an interlaminar insulation film with a paste compound comprising a specified amount of fluorinated carbon resin powder having a specified maximum grain size in terms of a resin portion mainly compound of resin portion contained in terms of a thermosetting resin varnish mainly compound of cyanic acid ester where plasma surface processing is carried out. CONSTITUTION:A chemical compound represented by the equation is favorable as cyanic acid ester where (m) in the equation is one or more, preferably two or more. Generally, (m) is an integer below 5. R represents an organic group where cyanic acid ester group is bonded with an aromatic ring of the organic group R. The maximum size of fluorinated carbon resin powder should be preferably 50mum and below in order to minimize the roughness of an internal wall when a multilayer printed wiring board is to be drilled. When the grain size is increased, the roughness of the internal wall is increased. The fluorinated carbon resin powder where plasma processing is carried out for a resin reactant 100 pts.wt. contained in the varnish as paste compound, ranges from 10 to 200 pts.wt. When it is 10 pts.wt. and below, the lower epsilon effect is small while the performance of thermosetting resin as a binder is lowered, thereby degrading the strength and the outside view, if it is 200 pts. wt. and over.

Title: Method for controlling dried exhaust gas temperature of organic waste
Inventor: FUJII TATSUHIRO
IPC: F26B21/10
Filed: 1982-04-22
Abstract: PURPOSE:To make constant the quantity of treated organic waste and to improve treating efficiency, by a method wherein temperature at the inside of a powder feed pipe is detected by a temperature controller, and based on the detected value, opening degrees of dampers located in a waste gas feed pipe are regulated. CONSTITUTION:In case temperature of dried waste gas flowing through a powder feed pipe 13 is, for example, below a given value, the temperature is detected by a temperature controller 27 to increase an opening degree of a damper 26, and this increases a quantity of waste gas fed in the powder feed pipe 13 through a waste gas feed pipe 25. This increases temperature of dried waste gas fed in a collector 12. Conversely, in case temperature of dried waste gas flowing through the powder feed pipe 13 is too high, temperature controllers 27 and 30 work to decrease the opening degree of the damper 26, to increase that of a damper 28, and to appropriately adjust that of a damper 29 so that temperature falls. As noted above, in case temperature of dried gas flowing out of a dryer is low, the dried waste gas may be elevated in temperature through the supply of waste gas into the powder feed pipe from an incinerator, and this permits a quantity of the treated organic waste to be made constant, and enables the improvement of treating efficiency.
