Title: Side guide equipment of strip coiling machine
Inventor: TAKASE HIROSHI
IPC: B21B39/14
Filed: 1993-09-24
Abstract: PURPOSE:To easily correct the meandering of strip even in the case of thin one and high speed passing by providing the strip guide device arranged with a nozzle to form high speed gas flow between a strip guide face and strip. CONSTITUTION:A high speed gas flow 37 is injected on the side of a strip guide face 31 from a nozzle 38 of a strip guide device 30 on a strip 2. Due to high speed gas flow based on Bernoulli principle, the pressure on the upper face side of the strip 2 is turned to lower than the pressure of still outside air on the rear face side on the strip 2, the strip 2 is sucked to the strip guide face 31 by differential pressure. When the strip 2 is sucked to approach the strip guide face 31, the gap between both becomes narrower, the air resistance of high speed gas flow is increased, weakening suction force, the strip 2 is floated at balanced position. The strip 2 is increased for apparent rigidity due to backing effect, not causing buckling and edge cracking by guide.

IPC: G09B9/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to automatically discriminate and display the signal of a pseudo target and the signal of a real target by comparing the relative speed calculated from the Doppler frequencies of a pulse compressed reception signal with the relative speed calculated from target motion. SOLUTION: An expanded pulse generator 3 modulates the pseudo target signal and the real target signal to expanded pulse in such a manner that pulse compression may be executed at the time of signal reception. A pulse compression signal processor 4 subjects the pseudo target and the real target signal inputted from an antenna 6 to pulse compression. A Doppler detector 11 detects Doppler frequencies from the pulse compressed signals. A speed calculator 12 calculates the relative speed of the target from the Doppler frequencies. A decision apparatus 13 decides that the target is the pseudo target from the calculated relative speed which is below the specified value.  As a result, manipulated variable is lessened as compared with the decision of the pseudo target and the manual impartation of the attribute and the reliability of the monitor of the real target during training may be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a sound field having abundant expansive feeling to a listener at an arbitrary position within a large range by executing crosstalk cancelling processing, reverse phase processing and mixing with respect to each of right/left input signals. SOLUTION: A crosstalk cancelling means removes right and left crosstalk signals from the right and left input signals R in and L in, for generating first right and left signals Rml and Lml. In addition, a reverse phase signal generating means mixes the reverse phase signals of the right and left input signals R in and L in for generating second right and left signals Rm2 and Lm2. Next, a mixing means mixes the first and second left signals Lm1 and Lm2 at a proper ratio to generate a left output signal L out and mixes the first and second right signals Rm1 and Rm2 at a proper ratio to generate a right output signal Rout. By executing crosstalk cancelling processing, reverse phase processing and mixing with respect to each of the right/left input signals such as this, the sound field with an abundant expansive feeling is formed.
