Title: Switched frequency synthesizer used for cavity resonator frequency controller
Inventor: SUGA HIROHIKO
IPC: H03L7/16
Filed: 1989-02-04
Abstract: PURPOSE:To reduce control reply time and to improve the control sensitivity by using a switched frequency synthesizer, setting an offset frequency so as to be correspondent to a Q curve half value width of an object cavity resonator, thereby setting the desired resonance frequency with the frequency synthesizer. CONSTITUTION:A frequency signal having a frequency four times the desired offset frequency DELTAf in phase locked with a reference signal outputted from a digital frequency adder circuit 3 is separated into four waves, a sine wave, a cosine wave and respective waves in opposite phase by a pi/2 phase shifter circuit. Either the sine wave or the cosine wave and the respective waves in opposite phase to them are switched and outputted synchronously with a switching signal at a changeover circuit. Then a sinusoidal wave (or cosine wave) with a desired offset frequency DELTAf, a cosine wave (or sine wave) and respective waves in opposite phase to them switched by the switching signal are outputted alternately. Thus, high speed switching is attained independently of the frequency setting time of a PLL circuit. As a result, the control sensitivity is improved and the replying time is reduced.

Title: Etching method for electrode foil for aluminum electrolytic capacitor
Inventor: NAKAHARA TAKEHIKO
IPC: C25F3/04
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain an aluminum electrolytic capacitor whose capacitance and strength are excellent by a method wherein the concentration ratio of sulfuric acid to hydrochloric acid in an etchant used in a DC electrolytic etching operation is set in a specific range. SOLUTION: In an etching method in which a DC electrolytic etching operation is performed before an AC electrolytic etching operation is performed to an aluminum foil, the concentration ratio (wt.% of sulfuric acid/wt.% of hydrochloric acid) of sulfuric acid to hydrochloric acid in an etchant used in the DC electrolytic etching operation is set in a range of 0.5 to 15. When the concentration ratio of sulfuric acid to hydrochloric acid is at 0.5 or lower, starting points of tunnel-shaped pits are concentrated, and a capacitance does not become large. When the concentration ratio is at 0.5 or higher and when the ratio of sulfuric acid is increased, the starting points of the tunnel-shaped pits are dispersed, a sufficient interval is obtained, and the capacitance becomes large.  However, when the concentration ratio is at 15 or higher and when the concentration of hydrochloric acid is low, the pits advance deep to the inside, and the strength of an electrode foil becomes weak. When the concentration of hydrochloric acid is high, the chemical dissolution of the electrode foil advances rapidly, and the pits are bored.

The amount of amine or the like used is normally and preferably at least 5wt.% or more with respect to the etherifying agent. When the degree of impregnation of the flame retardant etherifying agent is low, enough modification effect does not result. On the contrary, when said degree is too high, the deterioration of quality of material result. The favorable range of said degree is 25-30%.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a flexible joint which can prevent equipment damage and power interruption, when two equipments connected by a connection wire are swiveled in a separating direction by an earthquake. SOLUTION: A flexible joint 1 has a connector 2 secured to a conductor B1 and a connector 3 secured to a terminal W1 of a connection wire W, both the connectors are relatively displaceably connected by a shaft 4 passing through a slot 2d and a shaft through hole 3d.
