Title: Carrier holding apparatus
Inventor: IDETA NOBUHIKO
IPC: B41J19/20
Filed: 1990-10-02
Abstract: PURPOSE:To prevent the shift of printing or the out-of-phase of a motor by providing embossing on the part holding a carrier of a front stay to allow the surface thereof to protrude and increasing the flexural strength of the front stay. CONSTITUTION:A carrier 2 is loaded with a printing head 1 and a ribbon cartridge and moved left and right by a drive belt 7 while guided by the guide shaft 3 arranged in parallel to a platen 5. The front part of the carrier 2 is held by the front stay 6 made of sheet metal fixed to left and right frames 4. Embossing 8 is provided on the part holding the carrier 2 of the front stay 6 to allow the surface thereof to protrude to increase the flexural strength of the front stay 6. Since the deflection of the front stay is little even if the repulsive force of the printing wire of the printing head 1 is applied to the front stay 6 through the carrier 2 when the printing wire collides with the platen 5 for the purpose of printing, no printing shift is generated. Since the degree of parallelization with the carrier 2 is enhanced by this constitution, the irregularity of load at the time of the movement of the carrier is eliminated and trouble such as printing shift or the out-of-phase of a motor is reduced.

CONSTITUTION:After a field oxide film 7 has been formed on a p-type semiconductor substrate 5, a thin groove 6 is formed; boron ions are implanted; the assembly is heat-treated. If, during this ion implantation process, the substrate 5 is turned while it is inclined at an angle bigger than an angle theta which is formed between a diagonal line of the thin groove 6 and its side wall, a P-type diffused layer 9 can be formed. Then, an opening is made at a memory cell capacitor part 11; arsenic ions are implanted; the assembly is heat-treated. If, during this ion implantation process, the substrate 5 is turned while it is inclined at an angle bigger than an angle phi which is formed between the diagonal line of the narrow groove 6 and its side wall, an n-type diffused layer 10 can be formed. Then, an SiO2 film is formed on the surface of the substrate 5 which is not thermally oxidized. In succession, a polysilicon film which does not contain phosphorus (P) is deposited. By removing the polysilicon film and the SiO2 film other than the cell capacitor part 11, a capacitive insulating film 12 composed of the SiO2 film and a capacitor electrode 14 composed of the polysilicon film are formed.
