Title: Automatic connecting device of wire electrode and automatic connecting method therefor
Inventor: OKAZAKI HIDEJI
IPC: B65H69/00
Filed: 2000-10-26
Abstract: PROBLEM TO BE SOLVED: To provide an automatic connecting device of a wire electrode and an automatic connecting method therefor capable of connecting the wire electrode at a high speed. SOLUTION: At least one of factors having influence on a success rate of connection such as the thickness t of a work object is set as a parameter, and when the thickness t of the work object is smaller than a prescribed value T, a first mode is selected for connecting the wire electrode in a relatively short time by simplifying operation of plural devices operating at connecting time as much as possible or inserting the wire electrode at a high speed into an inserting hole formed in the work object. In this case, operation for lowering a guide pipe up to an upper side guide, operation for ejecting liquid and operation for sending out the wire electrode at a high speed almost simultaneously make progress. As a result, connecting time can be shortened by sending out the wire electrode at a high speed without reducing the success rate of automatic connecting operation.  When the thickness t of the work object is larger than the prescribed value T, a second mode is selected for basically successively operating the plural devices operating when connecting the wire electrode or sending out the wire electrode at a lower speed than the first mode so that the wire electrode is surely connected.

Title: Polar band-pass filter
Inventor: TAKAHASHI MOMOZO
IPC: H03H7/075
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a polar band-pass filter that utilizes a phase difference between a 1st resonance circuit and a 4th resonance circuit between 4 resonance circuits or more in multi-stage connection and couples both resonance circuits so as to generate attenuation poles thereby narrowing the pass-band. SOLUTION: The four resonance circuits 2, 3, 4, 5 are placed and interconnected in a channel shape, and a loop coupling means 7 couples the 1st stage resonance circuit 2 and the 4th stage resonance circuit 5. Since signals form the 1st stage resonance circuit 2 and the 4th stage resonance circuit 5 have a phase difference, the coupling means 7 adjusts it to form the attenuation poles (a) as shown in Fig. (b). Thus, the pass-band of the filter is improved as shown in solid lines A in Fig. (b) in comparison with a characteristic B of the conventional technology without the provision of the coupling means 7.
