Title: Lap seam welding equipment
Inventor: KATANOSAKA TAKASHI
IPC: B23K11/06
Filed: 1994-02-22
Abstract: PURPOSE:To enable welding of the ends of superposed steel strips without melting the aluminum of the part where comes into contact with a rotary electrode by structuring electrodes with a lower electrode and a rotary electrode and using pure copper for the material of the rotary electrode. CONSTITUTION:Lap seam welding is performed while rolling a rotary electrode 19 in a direction vertical to a paper face on steel strips 1a, 1b superposed on a lower electrode 18. Since the material of the rotary electrode 19 is formed with pure copper having little electric resistance, heat generation is less than heretofore at the contact part between the rotary electrode 19 and a 7000 series aluminum 20, lowering the surface temperature of the steel strips 1a, 1b that are in contact with the rotary electrode 19. Additionally, the cross-sectional shape of the outer periphery of the rotary electrode 19 is made semicircular, the area of the energizing part is made smaller, and thereby heat generation concentrates on a joint part between the steel strips 1a, 1b, and lap seam welding is performed stably.

Title: Head positioning servo device and method therefor
Inventor: SUZUKI DOSHU
IPC: G11B21/10
Filed: 1992-01-14
Abstract: PURPOSE:To quickly perform the positioning of a data head to a track center line by detecting off-track over the 1/2 of the data head in thermal off-track. CONSTITUTION:Servo patterns on respective data planes are read out at every data head when a power source is applied. When off-track quantity shows a value less than 1/2 off-track, the data head is positioned at the track center line on the data plane so as to set amplitude difference between a part B and a part C at zero. When the off-track quantity shows a value over 1/2 off-track, the slope of a position signal is switched to a track nearer to the track positioned at present out of the tracks adjacent to the track, and the head is positioned to the track center line 2 so as to set the amplitude difference between the parts B and C at zero. At this time, voltage offset by one circle obtained from the servo information is measured, and a mean value is found, and it is stored in a RAM, then, the off-track is corrected by adding the mean value when it is read out. In such constitution, off-track correction can be performed stably, and since the difference of amplitude levels is linearly changed, a fast response can be obtained.

Abstract: PURPOSE:To reduce the hunting of brake notch by a method wherein a holding region is set to be narrower as it approaches a stopping point by positioning a stop pattern between two patterns and a brake notch is held immediately before entering of a train into the holding region. CONSTITUTION:Hu pattern 10 is set up at the upper side of the stop pattern 2 corresponding to brake notch, and Hd pattern 11 is also set up at the lower side. Then, a holding region 12 gradually narrowing with an approaching of a train to the stop point is set up between the Hu pattern 10 and the Hd pattern 11.  The transfer of brake notch 13 is not done in such a holding region 12 and the  brake notch immediately before entering of a train into the holding region 12 is held. In this way, the hunting of brake notch can be reduced without deteriorating stopping accuracy.
