Title: Manufacture of semiconductor device
Inventor: HINOOKA KIYONOBU
IPC: H01L29/08
Filed: 1984-10-05
Abstract: PURPOSE:To prevent a short circuit between aluminum and a substrate in an N type diffusion layer section by forming a diffusion layer by an impurity having a small diffusion coefficient, shaping an silicon dioxide film through a rotary application method and forming a diffusion layer by an impurity having a large diffusion coefficient. CONSTITUTION:An silicon dioxide film 2 and a gate electrode 3 are shaped onto the surface of an silicon substrate 1, and a shallow diffusion layer 4 by a first impurity having a small diffusion coefficient is formed while using the gate electrode as a mask material. An silicon dioxide film 5 is shaped through a rotary application method, and baked. The silicon dioxide film is shaped thickly only at the stepped section of the gate electrode 3 at that time. A second impurity layer 6 having a large diffusion coefficient is formed while employing the gate electrode and the silicon dioxide film 5 as mask materials under the state, and thermally treated at a high temperature in order to activate an impurity. Accordingly, there is not possibility that aluminum penetrates because a diffusion layer in a section to which a contact hole is shaped is deep, and a section in the vicinity of the gate electrode does not disturb short channelling because there is only a shallow diffusion layer in the vicinity of the gate electrode.

Abstract: PURPOSE:To reduce p-n-p-n gains among cells and cells, and prevent the generation of bit interference by each changing the depth of emitters in a peripheral transistor and cell transistors. CONSTITUTION:SiO2 films 12, Si3N4 films and isolation SiO2 films 14 are formed on each collector region 11 in a peripheral transistor TR110 and a TR210 for a memory cell. Base regions 16 are shaped while using photo-resists 15 as masks, the films 13 are removed, and a base section in the TR210 is coated with a photo-resist 19. The film 12 on a base in the TR110 is removed, the resist 19 is removed, and an SiO2 film 20 is grown on the surface. Consequently, the SiO2 film on the TR110 is formed in thickness thinner than said film on the TR210. The film 20 is changed into phosphorus silicate glass films 21, 21' and phosphorus is diffused, and emitter regions 22, 22' are shaped. Accordingly, since the depth of the regions 22, 22' is changed, the n-p-n gains of the TR110 are increased, p-n-p-n gains between the cell and the cell are reduced, and bit interference is difficult to be generated.

Title: Printer with detecting mechanism for joint seal
Inventor: KOBAYASHI HIDEMASA
IPC: B41J11/14
Filed: 1987-08-25
Abstract: PURPOSE:To obviate jamming of a jointed double-ply continuous form paper, by providing a mechanism for enlarging the gap between a printing head and a platen when joint seals are passed between the printing head and the platen, based on a detection signal from a reflection-type sensor for detecting the joint seals. CONSTITUTION:When colored joint seals 1a, 1b adhered to a double-ply continuous form paper 3a, 3b are passed under a reflection-type sensor 2, the reflection level of the sensor 2 is lowered, and the joint seals 1a, 1b are detected. Then, a solenoid 9 connected to a platen 5 through a link 8 is excited based on a detection signal from the sensor 2, and the platen 5 is drawn downward against a force of a spring 8 by an electromagnetic force of the solenoid, thereby enlarging the gap between a printing head 4 and the platen 5. Then, the continuous form paper 3a, 3b is fed until the joint parts are passed completely through the gap, whereby jamming of the paper is obviated. After the joint parts are fed past the gap, the solenoid 9 is deenergized so that the platen 5 is pushed upward by the spring 6, thereby returning the gap to the initial state.

Abstract: PURPOSE:To share AC electric parts even if the voltage of commercial power source is different by comparing an AC input voltage with a reference voltage, discriminating which kind of voltage in two voltage groups of commercial power source it is and correspondingly changing the voltage. CONSTITUTION:AC power source 63 supplied from an input terminal is inputted to an input voltage detection circuit 64 in a low voltage power source 57. The input voltage detection circuit 64 discriminates whether the AC input voltage is more than 150 V or not. As for the voltage of 150 V, namely, more than the reference voltage, the AC input voltage is dropped to half. The AC input voltage is used as it is except for such case. Thus, the AC electric parts can be used without being conscious of the input voltage and the cost of the AC electric parts can be reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent fogging of an image from a used state till a life end state and to prolong life of developer by changing a frequency of developing bias AC voltage in accordance with using circumstances of two-component developer. SOLUTION: In an initial state of the developer, the image is formed by applying developing bias obtained by superposing AC voltage the frequency of which is 2 kHz to a developing roller, and adhesion of carrier is prevented from getting large so as to prevent a photoreceptor and a fixing roller from being damaged, and a high-quality image without white fogging is obtained. Meanwhile, as the number of image forming sheets gets large, the characteristic of the two-component developer in a developing device is changed and the while fogging on the image rises. In the used state where the electrification ability of the carrier is lowered, the image is formed by changing the frequency of the AC voltage from 2 kHz to 6 kHz when the number of printed sheets attains 80 k, whereby the high-quality image without the white fogging is obtained to the life end of the developer.
