Title: Manufacture of mos type semiconductor element
Inventor: MATSUDA HAJIME
IPC: H01L29/78
Filed: 1985-04-19
Abstract: PURPOSE:To minimize capacitance between a gate and a drain, and to increase the speed of operation by forming a gate electrode, shaping a low-concentration drain region through several-time ion implantation and also forming a high- concentration drain layer through ion implantation. CONSTITUTION:A channel stopper 2 and a field oxide film 3 are shaped to a substrate 1, a gate insulating film 4 is formed, and a gate polycrystalline silicon electrode 5 is shaped. A low-concentration drain region 6 is formed by using an ion implantation method. Since the region 6 requires depth deeper than a high-concentration drain region, ion implantation is divided into several times and conducted. The oxide film in a region as the high-concentration drain region 7 is removed, and the high-concentration drain region 7 is shaped to the oxide film section through the ion implantation method. Accordingly, only the annealing of anion implantation region is limited as heat treatment after forming a gate insulating film, and the overlapping of the low- concentration drain region can be minimized in a gate region, thus reducing capacitance between a gate and a drain, then increasing the speed of operation.

Title: Film winding mechanism
Inventor: SHIMADA TAKAHISA
IPC: G03B17/00
Filed: 1988-04-04
Abstract: PURPOSE:To effectively prevent the perforation of film from being damaged by adopting such a constitution that a sprocket rotates by play together with the film with respect to a sprocket shaft whose rotation is stopped when film winding is stopped. CONSTITUTION:Together with the film, the sprocket 17 rotates by the play between the projecting part 16b of the sprocket shaft 16 and the recessed part 17a of the sprocket 17 with respect to the sprocket shaft 16 whose rotation is stopped because film winding is stopped. When a winding stop lever 23 engages with a winding stop member 22, a lever 114 locks a locking plate 113 to stop the rotation of a spool 9. When a winding stop lever 23 engages with the winding stop member 22, the lever 114 locks the locking plate 113 to stop the rotation of the spool 9. Thus, the damage of the perforation of the film, its stretching and the reverse rotation of the spool 9 can be prevented.

Abstract: PURPOSE: To carry out the polymerization in such a manner as to prevent formation of gel-like polymer as much as possible, by providing a polymerization tank with an agitator shaft having blades for mixing the vapor phase and blades for mixing the liquid phase and with baffle rods secured in positions not obstructing the rotation of the blades and feeding a material through the vapor phase.  
     CONSTITUTION: An agitator shaft 4 is extended through a liquid phase 2 and a vapor phase 3 in a reaction tank 1. This shaft is provided with blades 5 for mixing the liquid phase and blades 6 for mixing the vapor phase. After starting rotation of the agitator shaft 4, a material such as ethylene is fed to the reaction tank through a material feed pipe 7.
