Title: Band pass type filtering device
Inventor: TSUKADA NOBUSHIGE
IPC: H01P1/213
Filed: 1979-02-22
Abstract: PURPOSE:To obtain the impedance characteristics of the constant resistance in addition to the high band attenuation property by forming the band blocking filter so as to obtain the mutual phase difference of 1/4 wavelength when viewed from the hybrid. CONSTITUTION:The input sent from terminal 12 is divided into two parts through hybrid circuit 2 and then transmitted to band blocking filters 4 and 5 with the equal amplitude as well as the phase difference of 1/4 wavelength. If the coincidence is secured then between the resonance frequency and the power frequency, the transmitted input is reflected by filters 4 and 5 to be transmitted to branching point 13 of circuit 2 with more addition of the phase difference of 1/4 wavelength and with the equal amplitude and the opposite phase each. Thus the input signal does not return to terminal 12, and the composite power is transmitted to terminal 11 to be then transmitted to terminal 10 through band pass type filter 1.

Title: Manufacture of rolled iron core
Inventor: YAMADA KAZUO
IPC: H01F41/02
Filed: 1985-02-07
Abstract: PURPOSE:To lower temperature within a rolled iron core and obtain a rolled core having excellent magnetic characteristics by setting a radius of curvature of corners of rolled iron core wound to amorphous magnetic alloy thin plate to a particular value or larger. CONSTITUTION:Since loss generated on a rolled iron core 1 by high frequency excitation changes in accordance with a manner of applying a bending stress when an amorphous magnetic alloy thin plate 2, it is not uniform in the entire part of rolled iron core 1. Therefore, temperature distribution of rolled iron core 1 during annealing is equalized by winding amorphous magnetic alloy thin plate 2 on an elongated non-magnetic bobbin 3. Namely, a radius of curva ture of corners becomes 40mm or more during the winding of rectangular rolled core 1. Therefore, iron loss in the circumferencial direction of rolled iron core 1 is equalized and temperature distribution within the iron core during annealing with high frequency excitation can be equalized.

At this time, when a notch 17a of a crank web 17 confronts with a discharge passage 24, the compressed air in the air chamber B is pushed out to the discharge passage 24. The capacity in the other air chamber A is increased so that fresh air is introduced into the interior thereof from an air suction pipe 26. Further, the compressed air of the discharge passage 24 is mixed with a fuel by a fuel supply means 15 and forced into a combustion chamber 9 from an intake valve 12.

Title: Variable velocity power generator, variable velocity pumped storage power generator and drive control of them
Inventor: IKEDA CHIKAMASA
IPC: F03B15/04
Filed: 1993-02-10
Abstract: PURPOSE:To continue operation without causing load cutting even when channel transient phenomenon is caused by load cutting of adjacent power generator or pumped storage power generator. CONSTITUTION:When a rapid closing signal Sg of the guide vane of adjacent pumping power generating motor is input into a velocity reduction command device 21, a velocity reduction command value N1 is issued by the velocity reduction command device 21. The velocity reduction command value N1 is sent to a cycloconverter 8 through a switch 22, an adder 23, a velocity limitter 24, a velocity controller 6, and an output limitter 7, while an exciting current serving as a rotational velocity lower limit is output from the cycloconverter 8. The inertia energy is converted into electric energy by a power generator 2 and a pump hydraulic turbine 1, and the energy is discharged to a system so that the rotation velocity is reduced to a lower limit. When hydraulic pressure begins to rise due to channel transient phenomenon thereafter, the increase in the energy caused by the rise in the hydraulic pressure is absorbed as inertia energy by the pump hydraulic turbine 1, and the rotation velocity is thus raised.
