Title: Manufacture of polytetrafluoroethylene porous material
Inventor: SHIMIZU NAOKI
IPC: B29C67/04
Filed: 1984-12-18
Abstract: PURPOSE:To obtain a porous material whose length of fibril and porosity are large, in other words, a grain diameter is controllable, by providing a preheating process prior to orientation. CONSTITUTION:Preheating for about 1-30min is performed at the temperature of 250-350 deg.C prior to orientation, in a manufacturing method of a porous material wherein a liquid lubricant is removed after polytetrafluoroethylene containing the liquid lubricant has been molded by a molding method under shearing terms and then the same is heated and calcined at the temperature of about 300-400 deg.C while an orientation state is being kept on. When a preheating process is inserted, parts wherein binding among PTFE particles becomes strong and weak are generated, deformation is generated from a weakened bond part at the time of orientation on the contrary the part where binding among particles has become strong does not deform and the part where deformation begins becomes few as a whole as compared with a case wherein the preheating is not applied. In consequence of the above, a quantity of deformation of the part where the deformation has been generated becomes abundant and a length of formed fibril becomese long.

Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent a transformer from being large in size, and to reduce the temperature rising of a semiconductor package in an ark welding machine to switch two input voltages being multiple relation as necessary. SOLUTION: When the lower voltage is inputted, the switching is made to a full bridge comprising four semiconductor devices in two semiconductor packages 4a and 4b. When the higher voltage is inputted, the heat generation of the semiconductor devices is diffused into two semiconductor packages 4a and 4b by making the switching from two semiconductor packages 4a and 4b to a half bridge comprising one semiconductor device and a smoothing part 3, and the left heat generating in one semiconductor package is reduced to about one half, and the temperature rising in the semiconductor package can be reduced. Two windings on the primary side of a main transformer 5 are unnecessary, and the increase in size can be prevented.
