Title: Wire guide member
Inventor: YAMANOGUCHI HIDENORI
IPC: B23H7/10
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce exchanging frequency by restraining abrasion of a guide member by at least covering a part to make contact with a wire with a hard carbon film Vickers hardness and thickness of which are made specific values. SOLUTION: At least a part to slide on a wire 1 is covered with a hard carbon film 25 of more than 4000 kg/mm2 Vickers hardness and of more than 1 μm thickness. Hereby, with less than 4000 kg/mm2 Vickers hardness of the hard carbon film 25, abrasion becomes extremely fast. Additionally, even with less than 1 μm hard carbon film thickness, film thickness is too thin in the same way and a base is exposed, and abrasion becomes fast. Consequently, the thicker the film thickness is, the more favourable it is, and it is favourable that it is more than 3 μm. When the hard carbon film 25 is applied, hardness is remarkably improved, abrasion can be effectively restrained, and consequently, it is possible to improve abrasion resistance and pitching resistance and to lengthen longevity of a guide roller 2 quite long.

Filed: 1985-06-05
Abstract: PURPOSE:To attain an automatic debug operation with high efficiency even for a program having the possibility for a program runaway or a bus error, by using a timer circuit which delivers a pulse after a prescribed period of time. CONSTITUTION:A control CPU 7 recognizes the generation of a break through a break control circuit 9 and controls a target muP2 via the circuit 9 to store the executing result of a program in a memory 3.

Title: Chopper controller of electric railcar
Inventor: SUZUKI TETSUJI
IPC: B60L7/00
Filed: 1984-06-14
Abstract: PURPOSE:To suppress plugging current immediately after converting by rising slower than a soft starting conduction rate in a normal mode for the prescribed period from a chopper operation starting point at direction converting time. CONSTITUTION:When a direction converting switch is switched to a reverse SR side in the state that the switch is shifted to a forward SF side, a chopper CH is opened for the prescribed time. A reverse magnet MR is excited in the meantime to close a contact mr. When the prescribed time is elapsed, a controller C starts controlling the conduction rate of the chopper CH. At this time, the conduction rate is increased at the rise slower than the normal soft starting until the operating period of the chopper reaches at the prescribed value. Thus, a plugging current immediately after converting a direction converting switch can be suppressed.
