Patent JP-S5621361-A (JP)
Title: Manufacture of dynamic memory cell
Inventor: NAKANO MOTOO
IPC: H01L21/265
Filed: 1979-07-31
Abstract: PURPOSE:To prevent the deterioration of transistor characteristics such as a threshold by preventing the formation of a barrier by a capacity P-N junction at the transistor gate region section of the memory cell of 1 transistor 1 capacity. CONSTITUTION:A field oxide film and an oxide thin film 7 for capacity are provided on a P-type Si substrate 5. A B additive poly Si 8 is stacked on the films and high temperature treatment is done in O2 to cover them with an SiO2 film 9. An N<+> layer 11 is made by applying resist masks 10 and by ion implantation. Next, the temperature of the substrate 5 is held at about 200 deg.C and the substrate 5 is exposed to an HF of several Torr. And selective etching removal is applied to the SiO2 9 only under the resist masks. The masks 10 are removed and photo etching is applied to the poly Si by consisting the SiO2 film 9 as a mask. The etching removal is applied to the side face B of the poly Si layer 8 for capacity electrode up to the position slightly behind the edge of the N<+> layer 11. Next, high temperature treatment is applied in H2 and the B is diffused from the poly Si 8 to make a P<+> layer 12 on the substrate 5. In this composition, the area of capacity electrode is smaller than the N<+> layer 11. Therefore, for the gate 13 of a MOSFET, the P<+> layer 12 will be formed without passing over the N<+> layer 11. So a barrier will not be formed and the characteristics of a memory cell will be improved.

IPC: H04N1/32
Filed: 1986-04-30
Abstract: PURPOSE:To increase the signal transmission speed of a picture signal of facsimile transmission and make this speed high-precision by monitoring both of the number of correctly received patterns and an equalizing error to discriminate whether training is successful or not. CONSTITUTION:Functions of MODEMs in the transmission side and the reception side are set up to the highest, and training of MODEMs is immediately started when a station to be called is discriminated.

Filed: 1984-05-15
Abstract: PURPOSE:To accurately perform detection operation, by appropriately adjusting the detection pressure of a sensor corresponding to the thickness of printing paper by making it possible to arbitrarily setting a reference value for comparing whether the electric resistance value of the sensor reaches a predetermined value. CONSTITUTION:When copy paper is used as printing paper 4, a variable resistor 34 is operated and the reference voltage value applied to the non-reversal input terminal 29b of a comparator 29 so as to be made low. A paper thickness detection signal is outputted from a comparator 29 in such a state that pressure-sensitive conductive rubber 25 has a high electric resistance value to stop a stepping motor 14. Because of this, a paper thickness detection sensor 24 is contacted with the paper 24 under weak pressure and the mark of a contact element 28 is not left. When the thick paper 4 is used, the variable resistor 34 is operated and the reference voltage value applied to the non-reversal input terminal 29b is set so as to be made high. The stepping motor 14 is stopped in such a state that the pressure-sensitive conductive rubber 25 has a low electric resistance value and the sensor 24 is contacted with the paper 4 under strong pressure. Therefore, the warpage or levitation of the paper 4 is removed and a detection error can be prevented.
