Patent JP-H02230775-A (JP)
Title: Manufacture of semiconductor device
Inventor: ARIMA HIDEAKI
IPC: H01L21/8247
Filed: 1989-03-02
Abstract: PURPOSE:To prevent the corner part of a first conductor layer from being pointed sharply, and keep a shape where electric field concentration is not generated by a method wherein, when a third oxide film is formed by thermal oxidation method, a first conductor layer is surrounded by a nitride film positioned in the upper part and a side wall spacer positioned on the side part, thereby cutting OFF the ventilation to the external atmosphere. CONSTITUTION:A part of a first gate oxide film 51 positioned under a side wall polysilicon layer 57a is eliminated, and then thermal oxidation is performed. By this thermal oxidation, a second gate oxide film 50a is formed on the main surface of a silicon substrate 50. In this case, a first polysilicon layer 52 is surrounded by a silicon nitride film 54 positioned in the upper part and a side wall polisilicon layer 57a positioned at a side part, and the ventilation to the external atmosphere is cut off. As a result, the progress of oxidation for the first polysilicon layer 52 is restrained during the thermal oxidation. Hence, even after the thermal oxidation is finished, the side part of the first polysilicon layer 52 keeps a superior shape as it is.

Abstract: PURPOSE:To eliminate the effect of the blur of an image at an edge part and errors due to the change in the amount of light, by measuring the amounts of light at a bright part and a dark part which are separated from the edge part having a brightness by specified amounts, and measuring the position of the edge. CONSTITUTION:The amount of the light of the optical image of the edge part having the brightness is detected by an image sensor. The detected signal (a) is differentiated twice, and a signal (c) is obtained. The amounts of light at the positions x1 and x2, which are separated from the peak position of the signal (c) by the specified amounts, are measured. With the average value of the amounts of the light at the two positions as a reference value, a value, which is equal to said value, is obtained. This value is made to be the edge position.

Title: Synchronized changing device
Inventor: HOSOYA KAORI
IPC: H04L7/00
Filed: 1995-03-13
Abstract: PURPOSE: To obtain the concrete constitution of a synchronized switching device capable of switching line without hit. CONSTITUTION: An active-side data signal DATAI is directly inputted to a switching circuit-7 and a reserving-side data signal DATAIS is delayed by a FIFO memory 12 to be a data signal DATAR and inputted to the switching circuit 7. A counting circuit 5 detects the relative delay time difference between both data signals inputted to the switching circuit 7 from a frame pulse generated by frame synchronization circuits 3 and 4. A control circuit 6 controls the frequency dividing rate N of an N-frequency divider 12 so as to eliminate the relative delay time difference. When a frequency dividing rate N is made larger than the frequency dividing rate M of an M-frequency divider 11, the delay quantity of the FIFO memory 12 is increased but when being made smaller, the delay quantity is reduced.  This control eliminates the relative delay time difference between both data signals inputted to the switching circuit 7 to attain syncronized switching.

Abstract: PURPOSE: To obtain developer carrying force by a projected part where an aperture for discharging developer in a developer storing container is formed by forming a spiral projected line on the inner surface of the peripheral wall of the projected part where the aperture part is formed. CONSTITUTION: When a motor for a bottle is started to be rotated, the driving of the motor is transmitted to a toner bottle 2 through a gear and a cylindrical rotation transmitting member, and the bottle 2 is rotated. The projected line 40 is spirally formed on the inner surface of the bottle 2. Therefore, toner stored inside is gradually fed to a toner discharge port 6, drops from the discharge port 6, passes through the toner dropping aperture of a cylindrical stopper, and is received by the toner receiver part of a hopper, then it is carried to the hopper part on an inner side from the front side plate of a copying machine by a toner carrying screw. The operation is continued until toner concentration in a developing device becomes a specified value and a toner supplying roller stops again.  Since the developer is stably carried on the inner surface of the projected part, the restriction in terms of the layout of the developer storing container is removed.
