Title: Thermal recording material
Inventor: IKEDA HARUHIKO
IPC: B41M5/337
Filed: 1986-05-20
Abstract: PURPOSE:To obtain high-sensitivity thermal recording material having a high thermal responsiveness, by incorporating a specific chemical compound in the thermal recording material containing normally a colorless or pale dye precursor and a color developer which develops the color of the dye precursor through reaction upon heating. CONSTITUTION:In a thermal recording material containing normally a colorless or pale dye precursor and a color developer which develops the color of said dye precursor through reaction upon heating, a chemical compound represented by the formula is contained as a sensitizer. The addition of a sensitizer is normally 5wt% or more for a color developer, and it is preferably 10-400wt%. If the addition is less than 5wt%, an improvement of the sensitivity is insufficient, and the addition of more than 400wt% is uneconomical. The dye precursors used for the thermal recording material are chemical compounds of triphenylmethane, fluoran, diphenylmethane, thiazine and spiropyran groups, etc. As color developers, acid substances used generally for thermosensitive paper, i.e. electron-accepting chemical compounds are employed; especially the phenol and aromatic carboxylic acid derivatives are preferred.

Filed: 1992-04-10
Abstract: PURPOSE:To follow even the sudden change of a groove part with good responsiveness by detecting the change of a groove wall by the change of a current and the voltage of welding. CONSTITUTION:The relation of the welding speed=(60 X welding current Xwelding voltage)/welding heat input is formulated. Pieces of information of a starting end, a terminal, a groove shape, etc., of the groove part are inputted from an operation part 80 as teaching data. A main control part 70 decides the number of welding layers, the thickness of welding layers and the number of passes at each welding layer based on these pieces of information and further, calculates the number of passes of each welding layer and the speed (moving speed in the X-axis direction) at the time of moving a welding torch 50 in the orthogonal direction to the welding direction based on an upper limit of the welding heat input. Welding of each pass of each welding layer is then performed based on these values. Since the moving speed control of the welding torch 50 is satisfactory for only either one direction of the welding direction and the orthogonal direction to that, it is simple.
